Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an indoor environment control material using charcoal.

[0002]

2. Description of the Related Art In modern architecture, the hermeticity of a room is improved and synthetic materials are often used for wall coverings, so that dew condensation, odor and generation of chemical substances in the room become a problem. ing.

Therefore, it has been studied to put Bincho charcoal on the wall or under the floor to control the humidity, but there is no means for solving all the problems such as the humidity control, the deodorization and the removal of the endocrine disrupters. Has been said.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an environmental control material capable of efficiently controlling such an indoor environment throughout humidity control, deodorization and removal of environmental hormones. And

[0005]

The present inventor has examined the characteristics of various charcoals, and as a result, found that a desired effect can be obtained by a combination of special carbon materials. completed.

[0006] That is, the environmental control material of the present invention is installed to control the indoor environment, using two or more different types of charcoal in combination, and one type of low-density bamboo charcoal. It is characterized by being

[0007] It is preferable that these charcoals are used by filling them in a breathable bag so that they can be easily installed in or around the room. This bag can be filled with charcoal in a stable manner and is easy to handle. Thus, it is preferable to provide small chambers in the bag so that different small coals can be stored separately in each small chamber.

According to recent research, bamboo charcoal has a very excellent humidity control effect and excellent deodorizing property. Especially, low-density bamboo charcoal has a hygroscopic property more than double that of Bincho charcoal and has a deodorizing property (such as ammonium and It is also known that the adsorptivity of hydrogen sulfide, etc.) is about three times or more that of charcoal. In addition, high-density bamboo charcoal has high deodorizing performance that is incomparable to ordinary charcoal and wood-based activated carbon (adsorption of ammonium, hydrogen sulfide, etc. is in the case of charcoal and wood-based activated carbon). It has been shown that its hygroscopicity is superior to that of charcoal such as Bincho charcoal, though it is inferior to low-density bamboo charcoal, although it has an excellent effect of two digits or more. Further, it has been found that activated carbon wood is inferior to bamboo charcoal in terms of humidity control and deodorant properties, but is relatively superior in adsorbability of organic compounds.

Therefore, for example, by using wood activated carbon, bamboo activated carbon and bamboo charcoal in combination as the charcoal, the charcoal can be effective for deodorization, humidity control and removal of environmental hormones. In this case, wood-based activated carbon is useful for removing environmental hormones, bamboo-based activated carbon (consisting of high-density bamboo charcoal) shows a very deodorizing property, and bamboo charcoal (relatively inexpensive low-density bamboo charcoal) is remarkable. It will exert a humidity control effect. The weight ratio of wood activated carbon, bamboo activated carbon and bamboo charcoal is 2 to 15: 2 to 15:96 to 7
It is good to set it to about 0.

Further, by using a combination of low-density bamboo charcoal and high-density bamboo charcoal, it is possible to obtain stable humidity control and deodorizing property for a long period of time. In this case, the low-density bamboo charcoal and the high-density bamboo charcoal have a weight ratio of 80 to 98: 2.
It is preferable to use it so as to be 0 to 2, particularly 85 to 95:15 to 5.

In the present invention, as described above, the bag is divided into the small chambers, and the small chambers are filled with the respective charcoal, so that the charcoal can be arranged with a stable density as a whole, The size of the bag is usually 30 to 60 cm, especially 35 to 35 cm, though it is desirable because it is easy and different charcoal can effectively exert their respective effects.
It is preferably about 50 cm and about 20 to 45 cm in length. The size of the small chamber in which the bag is installed depends on the material and amount of charcoal used, but the small chamber filled with low-density bamboo charcoal has a plurality of chambers with a width of about 5 to 20 cm. The room filled with bamboo charcoal, wood activated carbon, bamboo activated carbon, etc. should be smaller depending on the amount used,
It is preferable to form one piece or a plurality of pieces so as to be sandwiched between the small chambers containing the low-density bamboo charcoal.

In the present invention, the low-density bamboo charcoal is one that precipitates within 15 minutes when placed in water, and the high-density bamboo charcoal does not precipitate even after 15 minutes of placement in water. It is a thing. For low-density bamboo charcoal, Meng Song bamboo etc.
It is economically very useful because it is obtained by firing at a relatively low temperature of about 800 ° C.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION Next, examples of the present invention will be described. Example 1 A low density bamboo charcoal obtained by firing Meng Sung Bamboo at 600 ° C. and a bamboo bamboo at 850 ° C. in a bag made of a non-woven fabric with seams and a plurality of small chambers. The high-density bamboo charcoal was filled at a weight ratio of 90:10. In addition, each charcoal is
In order to prevent them from mixing with each other, they were divided into small chambers in the bag-the small chamber in the center of the bag was filled with high-density bamboo charcoal, and the upper and lower chambers were filled with low-density bamboo charcoal-.

When this bag is placed in the interior of a newly built house, the room where it is placed has no dew condensation compared to other rooms, has an unusual odor, and is very easy to live in. It was kept.

Example 2 A non-woven bag provided with seams and provided with a plurality of small chambers, coconut shell activated carbon, bamboo activated carbon, and bamboo charcoal (Mengsong bamboo fired at 450 ° C.) were weighed. And 5: 5: 9
Filled at a rate of 0. Each charcoal was mixed and filled into small chambers in the bag so that it would come into contact with the outside air without being mixed with each other.-The small chambers filled with coconut shell activated carbon and bamboo activated carbon are the same as those filled with bamboo charcoal. Provided so as to be located between

When this bag was placed in the interior of a house which had been plagued by offensive odors and dew condensation, it was confirmed from the next day that the generation of offensive odors and dew condensation was drastically reduced and the health of residents was gradually restored.

[0017]

EFFECT OF THE INVENTION The product of the present invention is capable of controlling the indoor environment in all of humidity control and deodorization and removal of environmental hormones.
It can be adjusted very efficiently. Therefore, it is possible to always keep the charcoal in an active state.
