Description
The present invention relates to a deodorizing agent for pet using purified water sludge and ash, and more particularly to a deodorizing agent for pet deodorizing agent which is formed by coating a positive charge material on a carbide obtained by calcining and carbonizing activated sludge mixed with purified water sludge, ash and limestone will be.
In general, clothing and shelter for human life is a basic essential element. Modern society is urbanized due to the development of industry and civilization, and lives in an artificial environment.
Even in the urbanized artificial environment, human instincts are eco-friendly, and there is a desperation to return to nature due to nature. There is a social contradiction due to economic development such as sickness due to nuclear family and aging, depression caused by loneliness and loneliness It is getting worse.
In the old farming society, small and medium animals such as hamsters, hedgehogs, and rabbits, as well as dogs and cats, were raised for shortage of food or breed for the purpose of sale, but now they are recognized as members of a family .
In urban areas, pet animals have been widely used as means for acquiring familiarity with nature and animals, knowing nature through sympathy and raising the quality of life, and increasing demand for various animals by animal lovers and enthusiasts have.
At present, many kinds of pets are raised in general households, sales offices, zoos and farms. In particular, small and medium animals such as cats, hamsters, hedgehogs and rabbits are family members, Trend.
In order to raise small and medium animals such as cats, hamsters, hedgehogs, and rabbits, home, food and other tools are required as well as people. Foods and animals In our case, Has been used.
As described above, since the pet is regarded as a member of the family and treated as a companion living together, various kinds of pet articles have been developed and used, and in particular, the concept of an animal is not simply a means of securing and sleeping, Like human beings, various facilities such as toilet space, feed space, and dragonfly space are constructed so that they can live in various play facilities and hygienic and clean environment.
However, although the pet is a member of the family and acts as a companion, it has a low intelligence and lives faithfully with the instincts of the animal, so that it emits bacteria and odors peculiar to animals, and odor caused by the large, And the secretion can not be treated by itself. Therefore, when it is cultivated indoors, various odors are generated, and clean sanitary management can not be achieved.
In the process of keeping pets such as cats, dogs, hamsters, hedgehogs, and rabbits in our homes, we use bedding made of rice straw, reed, wood sawdust or sand, pulp sand and so on.
In particular, in the case of cats, cat and sand are used as means for treating urine. The conventional cat sands as described above are used for simply dividing the floor and concealing the excrement. If there is no function and it is used for a long time, fine particles are generated due to drying, and it is a main cause .
In addition, since existing cat sands are greatly damaged by dust and have almost no function of feces, i.e., deodorizing function against odor, they are in need of deodorization against odor generated in feces.
Korean Registered Patent No. 10-1356232 (registered on January 21, 2014; hereinafter referred to as 'prior art document') has proposed a pet sand and a manufacturing method thereof. Prior art documents disclose pet sands consisting of a granular raw material composed of zeolite in powder form, an auxiliary raw material composed of bentonite and clay, and an additive consisting of baking soda and celluloses mixed and kneaded, rolled and dried to form granules, The mixture was mixed with 30 wt% of zeolite powder in an amount of 5 wt% to prepare 40 wt% of a secondary raw material composed of granular primary raw material having a size of 1 to 2 mm and granular zeolite having a particle size of 1 to 2 mm, The auxiliary raw material is mixed with 5 wt% of bentonite in powder form and 15 wt% of white clay, and the additive is composed of 3 wt% of baking soda, 2 wt% of celluloses, or 5 wt% of polyacrylamide 5 By weight to prepare pet sand.
Since the prior art document provides a deodorizing performance by mixing a substance having an adsorbing component in pet sand, the adsorbing ability to a substance smaller than the pore of the adsorbing component can not be provided. Therefore, a new pet There is a growing need for sand deodorants.

1 is a flow chart showing a process of manufacturing a sand deodorant according to an embodiment of the present invention;
Hereinafter, the present invention will be described in more detail with reference to examples. However, the embodiments are only illustrative of the contents and scope of the technical idea of the present invention, and the technical scope of the present invention is not limited or changed. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the technical idea of the present invention based on these examples.
1 is a flowchart illustrating a process for manufacturing a pet deodorant using purified water sludge and ash according to the present invention.
As described above, the pet deodorant for pets according to the present invention,
First, activated sludge is prepared by mixing water sludge, ash (ASH) and limestone.
The purified water sludge is supplied from a nearby water treatment plant. The general sludge is composed of an inorganic matter including 35 to 50% of SiO 2 and 20 to 30% of Al 2 O 3 .
In addition, the ash has to have received the supply of the product of Taean-fired power station, is received in the form of fly ash and bottom ash, the SiO 2 is 40 ~ 60%, Al 2 O 3 is 15 ~ 20%, Fe 2 O 3 10 ~ 20%, other TiO 2 , MgO and Cl.
The purified sludge and the ash are mixed with porous limestone to increase the surface area to produce an activated sludge having enhanced activity.
At this time, 100 to 200 parts by weight of ash and 5 to 20 parts by weight of limestone are mixed with 100 parts by weight of purified water sludge to produce activated sludge. Since the content of SiO 2 is higher than that of purified water sludge, the ash is mixed with limestone and there is a difference in strength of the granulated sintered product due to the difference in production rate of calcium silicate during sintering. That is, in order to obtain the effect of increasing the strength of the granules than the purified sludge, the mixing amount of the ash should be higher than that of the purified sludge.
Therefore, when the ash is mixed at 100 parts by weight or less based on 100 parts by weight of purified water sludge, the strength of the fired granules is lowered and the efficiency of recycling the purified water sludge is lowered. But it has a disadvantage that the specific surface area is lowered and the deodorizing effect is lowered. Therefore, it is preferable to mix and use in the above range.
In addition, when the limestone is mixed with less than 5 parts by weight, the increase in surface area is insufficient. When the limestone is mixed with more than 20 parts by weight, reduction of adsorption performance by limestone occurs.
In addition, 10 to 20 parts by weight of water may be further added to 100 parts by weight of the total weight in order to uniformly mix the purified sludge, ash and limestone. If the stirring time is short, mixing of the purified water sludge with the ash and limestone is not uniform, and if the stirring time is longer, the uniform mixing is not promoted, so that the preferred stirring time is 30 minutes to 3 hours.
In addition, activated sludge can be prepared by further mixing metal or metal oxide to increase the antimicrobial activity against microorganisms, bacteria or viruses.
Examples of the metal or metal oxide include yttrium (Y), molybdenum (Mo), bismuth (Bi), tellurium (Te), manganese (Mn), cobalt (Co), rhodium (Rh), iridium (Ni), palladium (Pd), platinum (Pt), copper (Cu), silver (Ag), gold (Au) and aluminum (Al).
The metal or metal oxide is preferably used in an amount of 0.001 to 0.2 part by weight based on 100 parts by weight of purified water sludge. When the amount is less than 0.001 part by weight, the antibacterial properties are insufficient. When the amount is less than 0.2 parts by weight, the effect of increasing the antibacterial activity is increased. However, since the metal or metal oxide forms a high price, Is preferably used.
The activated sludge is fired and carbonized to produce a fired product in the next step.
The sintering temperature is 400 to 600 ° C. and the sintering time is 1 to 3 hours to heat the organic material contained in the activated sludge to carbonize the sintered material. A part of the purified sludge constituting the activated sludge is fused by the firing to be combined with the adjacent components, so that a fired carbonized material having a particle size of 0.01 to 3 mm is produced.
If the calcination temperature is below 400 ° C., the drying and carbonization time of the activated sludge is long. If the calcination temperature is 600 ° C. or more, the drying and carbonization time can be shortened. However, And the particle size of the granules is excessively increased, so that it is preferable to add the above range.
In addition, in the calcination process, limestone (CaCO 3 ) receives heat and changes into porous lime (CaO) while discharging carbon dioxide gas. In this process, the surface area is further increased. In addition, some of the quicklime is combined with the silicic acid component of the purified sludge to change into calcium silicate (3CaO ㅇ SiO 2 , 2CaO ₄ SiO 2 ), and after the water is mixed, the crystallization is performed and the strength is increased to granulate the carbide .
The fired product in this step means a powder or a granule having a particle diameter of 0.01 to 5 mm, but the present invention is not limited thereto, and it may include a powder or a granule having a particle diameter of 0.01 mm or less. However, It is preferable to use those having a grain size of 0.01 to 5 mm and having a grain size distribution of 90% or more with respect to the total amount.
The fired product is further coated with a positive charge material by mixing.
The positively chargeable substance is selected from the group consisting of chitosan or quaternary ammonium group and is dissolved in a solvent to prepare a positive charge substance dissolution liquid. The positive charge material may be mixed with 0.01 to 5 parts by weight based on 100 parts by weight of the sintered material, and water or acid may be used as the solvent. When 100 parts by weight of the sintered material is mixed with 0.01 parts by weight or less of the positive charge material, the effect of providing a deodorizing force due to the potential difference of the positive charge material is insufficient. When the mixture is mixed with 5 parts by weight or more of the sintered material, But rather has a disadvantage in that the deodorizing performance is somewhat deteriorated.
The chitosan can be obtained by deacetylating chitin contained in the shrimp shell and shrimp shell in an amount of 60% or more, preferably 65 to 98%. The molecular weight of the chitosan is preferably in the range of 10,000 to 100,000. If the molecular weight is less than 10,000, the adhesive force is insufficient when coating the fired product, and the potential of the positive charge is lowered, so that the adhesion filtration rate of the fine dust or dust having a negative charge may be lowered. When the molecular weight exceeds 100,000, It is preferable to use the mixture in the above-mentioned range because the viscosity increases and the efficiency of the workability deteriorates.
As the solvent for dissolving the chitosan, citric acid, acetic acid which is an acid solution. Sulfuric acid, hydrochloric acid, and nitric acid. The acid solution may be diluted with water, and acetic acid is preferably used to prevent odor and environmental pollution.
In addition, the quaternary ammonium system may be selected from the group consisting of choline, carnitine, benzalkonium chloride; Denatonium; Cetrimonium bromide; Diallyldimethyl ammonium chloride; 3-chloro-2-hydroxypropyltrimethylammonium chloride (CHPTAC); 3-chloro-2-hydroxypropyltrimethylammonium chloride; Copolymers of acrylamide and quaternized dimethylammonium ethyl methacrylate (Copolymer of acrylamide and quaternized dimethylammonium methyl methacrylate); Poly (diallyldimethylammonium chloride); a diallyldimethylammonium chloride polymer; Copolymers of acrylamide and diallyldimethylammonium chloride (Copolymer of acrylamide and diallyldimethylammonium chloride); Quaternized hydroxyethylcellulose; Copolymers of vinylpyrrolidone and quaternized dimethylaminoethyl methacrylate (Copolymer of vinylpyrrolidone and quaternized dimethylaminoethyl methacrylate); Copolymers of vinylpyrrolidone and quaternized vinylimidazole (Copolymer of vinylpyrrolidone and quaternized vinylimidazole); Copolymers of acrylic acid and diallyldimethylammonium chloride (Copolymer of Acrylic Acid and Diallyldimethylammonium Chloride); Copolymers of vinylpyrrolidone and methacrylamidopropyltrimethylammonium (Copolymer of vinylpyrrolidone and methacrylamidopropyl trimethylammonium); Poly (acrylamide 2-methacryloxyethyltrimethyl ammonium chloride) (Poly (acrylamide 2-methacryloxyethylammonium chloride)); Acrylic acid, acrylamide and diallyldimethylammonium chloride (Terpolymer of Acrylic Acid, Acrylamide and Diallyldimethylammonium Chloride); Terpolymers of vinylcaprolactam, vinylpyrrolidone, and quaternized vinylimidazole; vinylcaprolactam, vinylpyrrolidone and quaternized vinylimidazole; And trimers of acrylic acid, methacrylamidopropyltrimethylammonium and methyl acrylate (terpolymer of acrylic acid, methacrylamidopropyl trimethylammonium chloride, and methyl acrylate). Water (distilled water) may be used as a solvent for dissolving the quaternary ammonium system.
The fired product and the positive charge material dissolution solution in which the positive charge material is dissolved are mixed and then stirred.
The stirring is performed such that the sintered material and the positive charge material solution are uniformly mixed so that the surface of the sintered product is uniformly coated with the positive charge material solution.
The stirring is preferably carried out at a speed of 1000 to 3000 rpm for 30 minutes to 2 hours to uniformly mix. If the stirring is performed for less than 30 minutes, the mixture of the sintered material and the positive charge material solution is not uniformly mixed to lower the coating rate of the sintered material. If stirring is performed for 2 hours or more, the uniform coating is insufficient, desirable.
When the stirring of the sintered material and the positive charge material solution is completed, the agitated material is put into an oven and dried to prepare an adsorbent or deodorant having a positive charge material coated on the sintered material.
The drying is carried out in a drying oven (dry oven). The drying oven is heated to a temperature in the range of 80 to 180 ° C and dried for 1 to 4 hours. Preferably, the drying time is shortened It is dried within a heating range of 100 to 180 ° C within 1 to 2 hours.
On the other hand, the deodorant having been dried by the coating can be further mixed with a water-soluble binder to form a predetermined size.
The above-mentioned molding is carried out by mixing a water-soluble binder with a deodorant and then pressing or extruding the water-soluble binder with a deodorant to form a predetermined size, or by spraying a water-soluble binder onto the diaphragm, And may be formed by forming a deodorizing ball into a predetermined size and then drying the moisture. The deodorizing ball can be formed in a range of 0.1 to 10 mm in particle diameter. The limestone is solidified by contact with water after sintering together with purified water sludge and ash, and the water-soluble binder is mixed, Deodorizing performance can be provided.
Examples of the water-soluble binder include starch, cellulose or a derivative thereof, alginic acid, gelatin, polyvinyl alcohol (PVA), a water-dispersible acrylic resin or a derivative thereof and a water-dispersible vinyl acetate resin as water- A hydrogenated rosin ester resin, a rosin-modified phenol resin, a terpene-based hydrogenated resin, a terpene-based hydrogenated resin, a rosin-based resin, a hydrogenated rosin ester resin, a rosin- Based resin, an alkylphenol-formaldehyde-based resin, a styrene-based resin, an aliphatic petroleum resin, an alicyclic petroleum resin, a copolymer petroleum resin , An aromatic petroleum resin, a xylene-based resin, a xylene formaldehyde-based resin, and the like, An oligomer-based tackifier such as polybutene or liquid-based rubber may be used.
The pet deodorant for pet of the present invention produced by this manufacturing method
100 parts by weight of purified water sludge is mixed with 100 to 200 parts by weight of ash and 5 to 20 parts by weight of limestone and sintered. 0.01 to 5 parts by weight of positively charged substance is coated on 100 parts by weight of the calcined sintered body to have a size of 0.01 to 5 mm do.
Here, 0.001 to 0.2 parts by weight of a metal or a metal oxide may be mixed with the fired product to provide sterilizing power.
The sand deodorant may be used in an amount of 10 to 100 parts by weight based on 100 parts by weight of general sand. If the amount is less than 10 parts by weight, the deodorizing performance is lowered. If the amount is more than 100 parts by weight, the degree of improvement of the deodorizing ability is insufficient, while the cost is increased.
The fabricated sand deodorant can adsorb and remove foreign matter or noxious gas by pores, as well as adsorb and separate fine dust or dust that is not filtered by pores by a positively charged substance coated on the adsorbent, thereby improving the deodorizing performance .
Since TiO 2 is partially contained in the components of the ash, when the deodorant is irradiated with light, TiO 2 exposed on the surface of the sand deodorant provides the effect of air purification, deodorization, antibacterial and organic decomposition by the photocatalytic reaction, Time can be increased.
In addition, the sand deodorant may be mixed with ordinary pet sand. That is, the mixing ratio of the sand deodorant to the total mixing amount of 100% by weight may be 20 to 100% by weight and the pet sand may be mixed with the remaining amount.
When the content is less than 10 wt%, the deodorizing effect is somewhat low. When the content is 100 wt%, the deodorizing effect can be maximized, but the cost is excessively consumed. Therefore, it is preferable to mix the sand deodorant with the total amount of the sand so as to be 20 to 50% by weight.
≪ Example 1 - Production of sand deodorant with controlled limestone mixing amount >
The purified sludge was supplied by the water treatment plant nearby Daejeon and dried. The ash furnace was supplied from Taean Thermal Power Plant and used as bottom ash crushed to a particle size of 10 ㎛.
100 g of purified water sludge was mixed with 100 g of ash, mixed with varying amounts of limestone, and stirred at 1500 rpm for 1 hour to prepare activated sludge.
The prepared activated mixture was charged into a calcining furnace and calcined at a temperature of 500 ° C for 1 hour to produce a calcined product.
10 g of deacetylated chitosan (molecular weight: 50,000) was mixed and stirred into a mixed solvent of 10 ml of acetic acid and 90 ml of distilled water to prepare a positively charged substance solution.
100 g of the prepared fired product was weighed, and 20 ml of the positive charge material solution having 10 g of the positive charge material dissolved therein was added thereto. Finally, 2 g of the positive charge material was mixed with 100 g of the fired product and stirred at 1500 rpm for 1 hour.
The stirred mixture was put into an oven and dried at a temperature of 120 ° C for 1 hour to be completely dried to prepare a sand deodorant.
TS-11 to TS-19 are adsorbents produced by the production method of the present invention using purified water sludge, ash, limestone, and positively charged substances, and SS-1 shows pure activated carbon to be compared.
Experimental Example 1 - Deodorization Experiment [
The sample of Table 1 was deodorized for ammonia.
1) 20 g of the sample shown in Table 1 was placed in a 5 L Tedlar bag, and 50 ppm ammonia was injected as a test gas. After injection, the sample was sealed.
The test gas was measured by the provisions of KS I 2218, and the temperature was maintained at 23 ° C and 4 ° C during the test and the humidity was maintained at 50 ° C and 10%.
Deodorization rate (%) = [(blank concentration - measured gas concentration) / blank concentration] ㅧ 100
The concentration of the test gas was measured at the initial (0 minute), 30, 60, 90 and 120 minutes, and is shown in Table 2 below.
As shown in Table 2, it was found that a high deodorization rate of 88.1% to 90.5% with respect to ammonia was observed in samples of TS-16 to TS-18 adsorbents coated with positively charged substances by mixing limestone with ash, similar to pure activated carbon . However, when the mixture of limestone is mixed with less than 5 parts by weight (TS - 11 to 15) of 100 parts by weight of purified water sludge, the degree of deactivation is lowered and the deodorization rate is somewhat lowered. - 18,19), but the deodorization rate was rather low. Therefore, the mixing of the limestone is performed by mixing at least 5 parts by weight of limestone with respect to 100 parts by weight of the ash, preferably mixing the limestone in the range of 5 to 20 parts by weight, more preferably mixing the limestone with 10 parts by weight .
≪ Example 2 - Production of sand deodorant with controlled amount of positively charged substance &
A sand deodorant was prepared under the same experimental conditions as in Example 1,
The mixture ratio of water sludge, ash and limestone was fixed and the amount of positive charge material was controlled. That is, a mixture of 10 ml of acetic acid and 90 ml of distilled water was mixed with a mixed amount of chitosan as a positively charged substance.
20 ml of the finally prepared positive charge substance solution was taken and mixed, and the content of the positive charge substance contained in 20 ml is shown in Table 3 below.
Experimental Example 2 - Measurement of Filtration Rate [
10 g of the sample of Table 3 was placed between the nonwoven fabric layers to prepare a 10-cm diameter filtration filter.
4 g of carbon black (trade name: Printex V-2) is accurately weighed and placed in an acrylic chamber of 1 ㅧ 1 ㅧ 1 m, blowing a small fan so that the powder of carbon black is scattered, And the residual amount of carbon black powder remaining in the filter was measured. The results are shown in Table 4 below. ≪ tb > < TABLE >
As shown in Table 4, when the positive charge material is coated in a small amount, the filtration rate of fine carbon black is high, and when the positively charged substance is coated over the adsorbent of TS-26, the degree of increase of the filtration rate is insufficient .
Accordingly, the mixing amount of the positive charge materials is mixed in a range of 0.5 or more, preferably 0.01 to 5 parts by weight, more preferably 0.5 to 3 parts by weight, relative to 100 parts by weight of the purified water sludge and 100 parts by weight of the ash It is desirable to provide a filtration ratio by mixing in the range.
≪ Example 3 - Production of a sand deodorant with different kinds of positive charge substances >
A sand deodorant was prepared under the same experimental conditions as in Example 1.
However, the mixture ratio of the purified water sludge, ash, limestone and positive charge material was fixed to the mixing ratio of TS-26, which showed excellent results in Example 2, and was changed to a typical positive charge material in the quaternary ammonium system as shown in Table 5 below, . In this case, the positive charge material of Table 5 was dissolved in water without dissolving in the acid material solvent of Example 2 and used.
<Experimental Example 3 - Measurement of Filtration Rate>
The filtration rate was measured in the same manner as in Experimental Example 2.
The sample had a filtration rate of 92.5 to 96.3% at 3.70 to 3.85 (g) in terms of residual carbon black. As a result similar to chitosan, the quaternary ammonium series can be used to produce an adsorbent according to the present invention.
≪ Example 4 - Production of sand deodorant mixed with metal or metal oxide >
A sand deodorant was prepared under the same experimental conditions as in Example 1.
However, the mixing ratio of water sludge, ash, limestone, and positively charged substances was fixed to the mixing ratio of TS-26, which showed excellent results in Example 2.
Chitosan was used as a positively charged substance, and silver (Ag) was used as a metal or metal oxide, and they were mixed as shown in Table 6 below.
<Experimental Example 4-Antimicrobial Test>
1 g each of the samples of Table 6 were taken in a flask and cultured for 24 hours for antibacterial evaluation test.
The strains of the antimicrobial activity test were carried out according to the method of bacterial count (KS K 0693) using E. coli ATCC 25922 and Staphylococcus aureus ATCC 6538, and the results are shown in Table 7 below.
As shown in Table 7, it can be seen that the basic antibacterial property is provided by the titanium dioxide (TiO 2 ), which contains the adsorbent property and the trace amount of ash without the addition of the metal component.
- repeated execution of antibacterial test
The antimicrobial activity test was repeated ten times using the sample once subjected to the antimicrobial activity test without changing the sample, and it was confirmed whether or not the number of bacteria was measured according to the number of experiments.
In TS-41 samples containing no metal components, bacterial counts were started to be measured 5 times. In TS-41 samples containing a small amount of metal components, bacterial counts were started to be measured in 7 times, 43 to < RTI ID = 0.0 > TS-49, < / RTI >
<Experimental Example 5 - Hardness Test>
The mixing ratio of the water slurry and the limestone and the positively charged substance was fixed to the mixing ratio of TS-26, which was excellent in Example 2, and chitosan was used as the positively charged substance. At this time, the mixing amount of ash was increased from 0 g to 50 g by weight with respect to 100 parts by weight of the purified water sludge, and the mixture was prepared as shown in Table 8.
For each sample, 100 g of particles having a diameter of 0.01 to 3 mm were received, and 15 steel balls each having a diameter of 12.7 mm and a diameter of 9.5 mm were prepared. The samples were put into a hardness test vessel together with the sample and stirred for 30 minutes.
The agitated material from which the steel balls were removed was sieved for 5 minutes using a sieve which passed particles having a diameter of 0.01 mm or less, and the residue was measured.
In the samples of TS-51 to TS-55 mixed with 100 parts by weight of purified water sludge and 200 parts by weight or less of ash, all of the samples were found to have a hardness of more than 95% In the samples of TS-56 and TS-57 mixed in excess by weight, the residual value was lowered to 90% or less.
In addition, the strength of the specimen with a diameter of 1 mm was measured.
The strength of TS-53 and TS-52, in which 100 parts by weight or more of ash was mixed with 100 parts by weight of purified water sludge, were higher than those of TS-51 and TS-52.
In addition, the TS-56 and TS-57 mixed with 200 parts by weight or more of ash with respect to 100 parts by weight of the purified water sludge were lower in strength. Therefore, mixing the ash with the purified sludge more than the purified sludge may increase the strength, and when mixed with the purified sludge more than twice the strength, it is preferable to mix the ash less.
In the light - irradiated environment, deodorization and antimicrobial functions were higher in the samples mixed with fine ash. It is considered that the adsorption performance is restored due to decomposition of harmful components by the photocatalytic reaction of titanium dioxide (TiO 2 ) contained in a small amount of ash, and thus it is understood that the performance is slightly improved by the photocatalytic reaction.
In addition, antibacterial test and deodorization test were performed on the samples mixed with ordinary sand and deodorant in the same manner. Generally, the higher the amount of sand deodorant mixture, the better the antibacterial and deodorizing performance. It is possible to provide effective antimicrobial and deodorizing properties in a test in which the deodorizing function is mixed with 20 to 50% by weight of the sand deodorant as compared to 100% by weight. In view of economical cost, .
