Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is, of horticultural planting栽材
Regarding the manufacturing method , used newspapers, magazines, and advertising paper
These a manufacturing method of horticultural planting material obtained by using a) of waste paper in the main raw material. 2. Description of the Related Art In recent years, global environmental degradation and improvement have been called for. In particular, waste paper such as old newspapers, magazines, and advertisements from ordinary households, which continue to grow in large quantities on a daily basis, and waste paper such as cardboard, OA paper, old newspapers, and magazines generated by companies, are subject to air pollution and warmth caused by incineration. Or the reduction of forest resources associated with the use of large amounts of paper. In Japan, where resources are scarce, recycling of used paper is widely regarded as reuse of resources, and it is extremely active. Initially, it was mainly used for paper products such as newsprint, wrapping paper, toilet paper, and coated paper.In recent years, however, it has not only been recycled to such paper products, but also used for exterior wall materials in the civil engineering and construction fields. Attempts are actively being made to obtain heat insulating materials, synthetic wood, heat insulating materials and heat resistant materials in the fields of ceramics and mining, fertilizers and soil improvement materials in the fields of agriculture, forestry and fisheries, and coating materials by recycling used paper. [0003] In view of the above, the present invention has been intensively studied to achieve the reuse of waste paper, and as a result, if the waste paper can be recycled as a planting material for horticulture,
The inventors of the present invention have focused on the fact that paper obtained from a tree can be returned to a plant after use to increase greenery, thereby contributing to the improvement of the global environment. [0004] [0005] According to an aspect of the invention according to claim 1, dissolving the waste paper, ink component remaining in the crush fiber content of waste paper obtained by crushing, removing the alkaline component Step, a step of forming the hydrated fiber component from which the ink component and the alkali component have been removed into a lump, a step of crushing the lump, a step of crushing the crushed fiber of the waste paper obtained above as a main material, and adding a glue material to the crushed fiber. Mixing and kneading filler, ceramic powder, bamboo charcoal and driftwood charcoal powder, kneading, ripening the above kneaded material to adjust the water content, and then putting it into a rotating cylinder having one or more rotating cross blades inside Then, the step of powdering with a rotating cross blade, the step of shaping the powder material into a granular material while rotating in a rotary cylinder having an induction spiral groove, the same guiding spiral groove structure as above in a hot air chamber in a hot air chamber Rotated inside the rotating cylinder While drying, is characterized in the preparation of horticultural planting 栽材 using waste paper consisting of capital. According to the first aspect of the present invention , a fiber component obtained by treating used paper is used as a main material, and a glue material, a filler, a ceramic powder, and a bamboo charcoal powder are blended, kneaded, aged, and mixed.
By shaping and drying, it is possible to separate planting materials with different particle diameters such as large, medium, small, and very small, and to obtain them separately. Since it has characteristics such as good properties and good water retention, it can be used as a planting material in indoor cultivation in a flowerpot or planter rather than in outdoor plant cultivation. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an example of a method for producing a planting material according to the present invention will be described step by step. First, the production of a water-containing fiber by a waste paper recycling process will be described. Used paper used in the present invention includes newsprint, magazines, and advertising papers. It is preferable that ordinary newspapers and dark color prints such as magazines and advertising papers are separately processed and used. That is, since there is difficulty in the decoloring operation between newsprint and dark color prints, it is necessary to separate them in advance and to carefully perform the immersion and washing steps for dark color prints. [0008] After the used paper made of the newspaper collected and sorted as described above is cut by a shredder, this cut paper waste is put into a pulper, water is added to the input cut paper waste 30 at a ratio of 70, and about 24 at room temperature. Stir for a long time to allow the cut paper scraps to be sufficiently moistened to swell. [0009] The above-mentioned cut paper waste swollen with water is sufficiently washed by adding hot water of about 55 ° C while flowing and stirring. Thereafter, the washed cut paper waste is transferred to a container having a wire mesh attached to the bottom of the opening, and is left still in a state where excess moisture naturally flows out of the container from the wire mesh at the bottom. Next, excess water is removed without the forced squeezing, and the cut paper waste swollen with water is put into a steaming pot, and water in which an alkali chemical and a detergent are dissolved is added.
Under high-speed stirring, the mixture is sufficiently boiled at a temperature exceeding 100 ° C. for about 2 hours, and then sent to a separator to separate the fibers into garbage. Next, the fibers separated from the refuse are transferred to a container having a small mesh wire mesh at the bottom of the opening, and a large amount of room temperature water is poured into a shower state for about 2 hours while preventing outflow of the fibers. The fibers are washed and most of the dye and alkali adhering to the fibers are removed by the washing. Next, in the dehydration step by a centrifugal dehydrator, the removal of water adhering excessively to the fiber component, and the complete removal of the dye and alkali still remaining in the fiber component in a trace amount,
A lump of fibers having a water content of about 30% is obtained. The obtained lump is left as it is to equalize the moisture with the fiber (so that the moisture is evenly contained in the fiber) so that the subsequent shaping operation to the grain shape is facilitated. This is very important. Thus, the lump of the fiber having the uniformed water content is then loosened into a floc using a punch or crusher. In addition, the fibers that have been loosely separated contain water uniformly. This loosening is carried out by a lump of fibrous material with uniform moisture sliding through the gap between the rotating body where the flat spatula plate rotating at 1000 rpm and the brush-like agitator intersect. Next, a method of producing a planting material using the hydrated fiber component of the sufficiently loosened waste paper obtained above will be described. The planting material of the present invention is mainly composed of the hydrated fiber component of the above-mentioned waste paper, and is filled therein. The material, ceramic powder, bamboo charcoal, driftwood charcoal powder, and paste material are added and kneading is sufficiently repeated, followed by aging, pulverization, granulation, drying, and granular separation. The filler is added to give weight to the fibrous body of the used paper, and gives weight to the granular planting material obtained from the fibrous body. As the filler, kaolin, clay, bentonite, talc, calcium carbonate,
Among them, magnesium carbonate and the like are used, and when clay is used, the plant is easy to adapt to and is effective when using this planting material because even a small amount of soil is contained. An appropriate amount of such a filler is 4 to 8% by weight based on the hydrous fiber content of the waste paper as the main material. The ceramic powder emits far-infrared rays due to sunlight, which raises the temperature slightly. Therefore, if a planting material to which the powder is added is used, the growth of the plant is good and the progress to fruiting is good. An appropriate amount of addition is 2 to 5% by weight based on the hydrous fiber content of the waste paper as the main material. In addition, the bamboo charcoal and driftwood charcoal powder has an effect of suppressing microorganisms and an effect of preventing nesting of insect damage.
Further, since the main component of the planting material of the present invention is a fiber of waste paper, there is an effect of preventing and suppressing decay and generation of an unpleasant odor of the compost in a state of being wet for a long time. The amount of addition is suitably from 1 to 4% by weight based on the hydrous fiber content of the waste paper as the main material. The sizing material is used for the purpose of solidifying the waste paper, and the added amount is 2 to 7%.
Preferably, polyvinyl alcohol or vinyl acetate resin is used. The above-mentioned materials may be kneaded using a conventional kneader or kneading machine, and the materials are kneaded sufficiently at room temperature until they become a rice cake state. It may be performed under ventilation depending on the situation. The fully kneaded rice cake-like kneaded material is then left for a whole day and night to be aged sufficiently to equalize the water content of the whole kneaded material. This is because the kneaded material immediately after kneading has a rice cake-like appearance, but there is a concern that the above-mentioned input material remains as it is without being sufficiently kneaded inside, This is because the rice cake in such a state cannot be cut into pieces at the time of crushing by the cutter or crusher in the next step. Therefore, the part left as it is in the rice cake-like product by the ripening of the above-mentioned day and night is sufficiently adapted to moisture to make the whole rice cake-like material uniform. The rice cake-like material having been subjected to the above-mentioned water equalization is then cut into pieces by a cutting machine or a crusher, and then put into a rotating cylinder having at least one rotating cross blade inside. I do. Then, one or more rotating cross blades can be rotationally converted to 100, 300, 500, and 600 rpm, respectively, and are subdivided by hitting the one or more rotating cross blades. Then, the finely divided powder material is 3 m
When rotating and shaping at a speed that passes through a rotating cylinder with a guide spiral groove of about 3 minutes in about 3 minutes, it becomes a soft rice cake-like large grain, medium grain, small grain, or powder, and exits from the rotating cylinder. Come. Then, while rotating these in a rotary cylinder having the same induction spiral groove structure provided in a room at about 120 ° C., the rice cake is dried as large, medium, small or powdery rice cakes and solidified. And finally, these are sorted into large, medium, small or fine powder by a sorter, so that planting material for each particle size can be obtained. here,
A large grain is a grain size of 14 mm or more, a medium grain is 7 to 14 mm, a small grain is 2 to 7 mm, and a grain size of 2 mm or less is a very small grain and further fine powder. The planting material according to the present invention thus obtained is as follows: (1) Large and medium grains. , Small particles, ultra-small particles, and fine powder, and can be produced in various shapes, and these can be used alone, that is, without mixing with other soils, and used as potted plants or planter soils only with planting materials. (2) It has good air permeability and drainage, and also has excellent water retention. (3) Since it is manufactured by drying at high temperature, sterilized, and clean, it is most suitable as indoor pot planting soil. It has such features. Next, a method for producing a planting material of the present invention will be described in detail with reference to examples. (1) 1 kg of 30% water-containing fiber content of used paper, (2) 60 g of clay powder, (3) 35 g of ceramic powder (trade name: Ceragit k-5, manufactured by Shiraishi Industry Co., Ltd.), (4) 23 g of bamboo charcoal powder,
(5) 35 g of a 10% aqueous solution of polyvinyl alcohol;
(6) A material of 23 g of a 50% aqueous solution of a vinyl acetate resin was prepared, and charged into a usual kneader or kneader sequentially from (1), and kneaded sufficiently until it became a rice cake state. The rice cake-like kneaded material sufficiently kneaded as described above was then left at room temperature for 24 hours to allow it to mature sufficiently. Then, after trying to equalize the water content of the whole kneaded material, it is cut into pieces by using a cutting machine, and then the cut rice cake is turned into a rotating cylinder with one or more rotating cross blades inside. Put into the body. After the rice cake-like material thus introduced is fragmented, the fragmented powder is supplied to a rotary cylinder having a guide spiral groove therein. As a result, the supplied powder is guided to the outlet of the rotating cylinder while being divided into various sizes by the impact of the rolling hit in the guide spiral groove while rotating, and is discharged from the outlet. The discharged rice cakes of various sizes are then put into a rotating cylinder having the same induction spiral groove structure placed in a room at about 120 ° C., and dried while rotating to solidify. Let it. Thereafter, the solidified granules are separated by a sorter into large grains as described above:
mm or more, medium grain: about 7-14 mm, small grain: about 2
77 mm, ultra-small grains: about 2 mm or less, and fine powder, which are obtained as planting materials. Actually, when planting materials such as cattleya or phalaenopsis, or mizuho peach or flowering trees were tried using only the planting material of the present invention having the above-mentioned particle size and fertilizer components, the flowering and fruiting were excellent. Was observed. Although the planting material as a granular material has been described above, the planting material of the present invention is not limited to such a granular material. It is also possible to obtain a rod-shaped planting material by cutting it into a flat plate shape and then cutting it to a length of about 1 to 3 cm. As described above, the crushed fiber content of the used paper obtained by dissolving and crushing the used paper is used as the main material, and the glue material, the filler, the ceramic powder, and the bamboo charcoal powder are added thereto. The planting material of the present invention obtained by kneading, maturing, granulating, and drying was found to be excellent in aeration, drainage and water retention, and was useful as a horticultural soil.
