Description of the Related Art It has been reported in several patent publications that charcoal boards made from bamboo charcoal while keeping the inherent pores in an active state are excellent in dehumidification, deodorization, sound absorption and electromagnetic wave shielding properties. It is disclosed and described in publications and is well known. However, these known charcoal boards are:
With only one exception, the use of petrochemicals in the binder has a high risk of producing formaldehyde odors or releasing substances that cause atopic dermatitis.

Alternatively, a charcoal board that is pressure-formed in a block shape is disclosed. Although this charcoal board is effective for underfloor humidifiers used on the ground under the floor of a house and for deodorizing plates installed in a treatment tank for livestock manure, it is difficult to reduce the weight and thickness. There's a problem.
Although this patent publication discloses a mixture of a synthetic resin binder, the use of cement is an essential requirement, and this charcoal board does not solve the problem of weight reduction and thinning.

That is, first, powdery or granular bamboo charcoal 11 and glucomannan of about 1.5 to 6.0% by weight with respect to bamboo charcoal 11 were added with water 13 and sufficiently kneaded with a stirrer. Water 1 added for kneading
In No. 3, about 45 to 90% by weight of bamboo charcoal 11 was sufficient. As shown in the flow chart of FIG. 2, this glucomannan powder 12 has undergone a water absorption / swelling step S4, that is, a swelled glucomannan 17 that has been well dispersed in a suitable amount of water in advance and has absorbed and swelled to some extent.

It has been found that a small amount of glucomannan powder mixed as a binder with powdery or granular bamboo charcoal is sufficient, specifically, about 1.5 to 6.0% by weight of bamboo charcoal is sufficient. .

料を提供できる程度のものであればよい。Further, in order to mix a small amount of glucomannan with the powdery or granular bamboo charcoal as a binder, water was added to these materials and kneaded sufficiently with a stirrer. Through this kneading step, a charcoal molding material was obtained in which bamboo charcoal and glucomannan were uniformly mixed and could be efficiently poured into a mold in a required amount. The amount of water to be added to the powdery or granular bamboo charcoal and a small amount of glucomannan is a charcoal molding material in a kneaded state with a hardness that allows them to be evenly mixed and efficiently poured into the mold in the required amount. Anything that can be provided can be used.

選ばれることになる。Furthermore, a predetermined temperature and a predetermined time are required for pressure molding with a hot press machine. These predetermined temperature and predetermined time are necessary for at least calcium and other alkali elements in the charcoal of the charcoal molding material to react with glucomannan and solidify. The predetermined temperature is 1
It turned out that about 00 ° C. is sufficient. However, it has been found that the predetermined time is not constant and varies depending on the size of the charcoal molded product to be produced and other production conditions. The pressure applied by the hot press machine is not constant because it is almost released at an extremely early stage due to the presence of air, the collapse of charcoal, and the like. In short, the optimal initial pressure will be selected according to the size of the charcoal molded product to be produced and other production conditions.

3cm square size, its volume specific gravity is 0.27 ~ 0.5
The strength of the charcoal board of the below-described product of 4 g / cm 3 was confirmed to have a bending strength comparable to that of a styrene foam board of the same size. That is, after sufficiently drying each board and leaving it in a room for a certain period, three test pieces having a width of about 40 mm and a length of about 200 mm are cut out from each board, and three points (central concentration) are obtained.
As a result of the bending strength test performed by the weighting method, the average of the bending stress degrees of the three test pieces was 0.91 MPa for the third embodiment,
1.36MPa for the fourth embodiment, 0.78M for the fifth embodiment
Pa, the seventh product was 0.21 MPa, and the eighth product was 0.36 MPa. Although it depends on the expansion ratio, the bending strength of the styrofoam board is 0.2 to 1.0 MPa (2
-10 kgf / cm 2 ), it can be seen that each of the examples has a bending strength that can be compared with that of the Styrofoam board. Therefore, the charcoal board according to the present invention has sufficient strength that it is not broken even when used under a tatami or carpet. It was also recognized that the charcoal board according to the present invention hardly differs from the bamboo charcoal itself in gas adsorption capacity. This is because the amount of glucomannan powder added as a binder to bamboo charcoal is as small as several percent or less by weight.
