Abstract
Description
The present invention occurs in furniture made of adhesives and wood, etc., and can prevent the occurrence of atopic dermatitis and bronchitis by oxidizing formaldehyde, which is a cause of sick house syndrome, with formic acid, and contaminated air in water, carbon dioxide, etc. Absorb and generate oxygen to improve air quality, increase oxygen generation by manganese dioxide, activated carbon, etc., and maintain oxygen generation rate stably to extend the life of harmful gas remover and replace imported potassium peroxide The present invention relates to a composition for removing harmful gases and generating oxygen, a cartridge and a pouch, which can significantly lower the production price.
Recently, various studies have been conducted on how to remove formaldehyde, which is a factor of sick house syndrome. This is because formaldehyde is interpreted as a direct cause of sick house syndrome along with HOC's and volatile organic substances (VOC's). One of the causes of children's asthma and atopic dermatitis, which is emerging as a social problem, It is believed to be formaldehyde.
The easiest way to remove formaldehyde indoors is to ventilate it. However, natural ventilation has a weak effect of removing formaldehyde, and in many closed buildings, air conditioners are used in summer and heaters are closed in winter, so ventilation is not easy.
Moreover, overheating in the winter months can accelerate the release of lower aldehydes. Although it is possible to consider a method of forcibly ventilating the indoor air by using a ventilation facility, in this case, there is a disadvantage in that the installation of the device is expensive.
Thus, simple and inexpensive formaldehyde removal methods have been tried in various ways.
The most widely used technique for removing formaldehyde is to use an adsorbent such as activated carbon. Activated carbon is a porous material with a very large surface area, which removes formaldehyde by physical adsorption. For example, Korean Patent Publication No. 2004-0035638 discloses a curtain using charcoal.
In addition to activated carbon, adsorption by loess has also been attempted. However, these adsorbents are difficult to fundamentally remove harmful substances and have disadvantages of low adsorption efficiency. In addition, formaldehyde adsorbed on an adsorbent such as activated carbon is not permanently removed, but once the adsorbed state is lowered, the concentration of formaldehyde is characterized by being desorbed and released to the surroundings.
In addition to activated carbon, it is known to use porous adsorbents such as activated clay, silica gel, and activated alumina, but these are also known to have low adsorption performance and problems in their persistence.
Therefore, the impregnated activated carbon in which the chemical reacts with formaldehyde on the activated carbon is sometimes used as a method to compensate for the disadvantage of the adsorbent.
Impregnated activated carbon is activated carbon that reacts with the substance to be removed or reacted with activated carbon.Although the target material shows very strong removal performance, it is expensive and it is actually removed because of the limited amount of chemicals or catalysts attached to the activated carbon. The disadvantage is that the amount of material that can be made is relatively small.
As one of the methods for removing formaldehyde, there is a removal method using an oxidation catalyst. In this case, a metal oxide is used as a catalyst, and titanium dioxide uses a principle of oxidatively decomposing lower aldehydes when subjected to ultraviolet rays, and is relatively useful in that lower aldehydes can be fundamentally removed by a chemical reaction. Although it can be done, where the amount of light is small, its performance is difficult to express, and in particular, there is a disadvantage in that titanium dioxide particles must be processed on a nano scale.
Referring to recently registered Korean Patent No. 10-0480808, a method of removing formaldehyde using an oxidizing agent such as sodium percarbonate is disclosed. The patent discloses hydrogen peroxide contained in sodium percarbonate as a method of removing lower aldehydes including formaldehyde. The oxidation power of is used.
The above-mentioned domestic No. 10-0480808 removes formaldehyde by using relatively inexpensive sodium percarbonate as an oxidizing agent, and thus shows excellent performance in removing formaldehyde in a limited or confined space.
However, the oxidation power of sodium percarbonate is limited to the surface of the grains of sodium percarbonate particles, so when all of the hydrogen peroxide on the surface portion is consumed, the removal efficiency drops sharply, and the oxidation power is much lower than that of the hydrogen peroxide itself.
However, the conventional oxygen generation and formaldehyde removal compositions, cartridges and pouches configured as described above have various problems as described above.
An object of the present invention is to solve the problems of the prior art as described above, by removing the harmful gas that can prevent the occurrence of atopic dermatitis and bronchitis by oxidizing the formaldehyde generated in the furniture with formic acid and adsorbed with activated carbon. For compositions, cartridges, and pouches.
Another object of the present invention is to provide a composition, a cartridge and a pouch for removing harmful gases and generating oxygen that can improve the quality of air by absorbing moisture, carbon dioxide, and the like in contaminated air in an enclosed space.
Another object of the present invention is to increase the generation of oxygen by manganese dioxide, activated carbon, etc. and to maintain the rate of oxygen generation stable to extend the life of the toxic gas remover and at the same time to replace the imported potassium peroxide, which can significantly reduce the production price To provide a composition, cartridge and pouch for removing harmful gases and oxygen generation.

(3)
HCHO + ½O 2 → HCOOH

According to Formula 3, the oxygen generated in Formulas 1 and 2 oxidizes formaldehyde to formic acid, thereby reducing the amount of formaldehyde. In addition, activated carbon adsorbs formaldehyde, thereby reducing the amount of formaldehyde. In the case of using activated carbon, the removal of harmful gas and generation of oxygen are increased by increasing the rate of oxygen generation due to adsorption of activated gas by activated carbon and securing of space by activated carbon between calcium oxide than when activated carbon is not used.
The peroxide of the metal is preferably selected from the group consisting of calcium peroxide or magnesium peroxide, but calcium peroxide is most preferred. This is because they are both oxidative and stable in the atmosphere.
