2. Description of the Related Art In recent years, various odor-generating conditions have become complicated, but the technology to deal with them has been extremely inadequate, and the present situation is that the odor pollution does not seem to improve. As a conventional deodorizing treatment method for bad odors, an active adsorption method, a catalytic combustion method, an oxidation method using ozone or a chemical agent, a neutralization method, a bacterial decomposition method, an enzyme method and the like are known. However, all of these have high running costs and management difficulties. In addition, since it has poor sustainability, it has many drawbacks such as relatively low deodorizing efficiency. Of the above-mentioned known deodorization treatment methods, the method of decomposing malodorous gas using a chemical agent having an oxidizing action is the most effective, but since potassium dichromate, sulfuric acid, etc. are generally used as a chemical agent, be careful in handling. This treatment method is unfavorable for general use because of the necessity of high temperature, the risk of secondary contamination by chemicals, and the high reaction temperature. Therefore, in order to solve the above-mentioned drawbacks, the applicant of the present invention (Ask Screen Co., Ltd.) devised a patented invention of Japanese Patent Publication No. 63-5763 (Japanese Patent No. 1508998) and a Japanese Utility Model Publication No. 1-73334. Thus, a deodorant which can decompose a deodorizing substance by a catalytic action in a short time, has a long life, is free from the risk of secondary contamination, and is improved in practicality is provided. Then, the optimum amount of water in the deodorizing effect of the deodorant according to the above-mentioned patented invention, etc. was obtained by the following measurement method by the predetermined measurement method. [Measurement method] 30 ml of deodorant drug substance in 125 ml vials
After adding 0 mg and adding water (water content 0, 3.3
%, 10%, 15.6%, "Note 1" 17.7%, "Note 2" 20
%, “Note 3” 3.50%, 66.7%, and 33%). An initial concentration of 7,000 ppm of ethyl mercaptan was added, and the amount of gas remaining after 5 minutes and 30 minutes was measured by the GLC method to obtain the residual rate. Note that the above “Note 1”
Is 8 times the mol of the deodorant drug substance, "Note 2" is 9 times the mol of the deodorant drug substance, and "Note 3" is 10 mol of the deodorant drug substance.
It is twice the mole. [Results] As shown in Table 1 below, the optimum amount of water is 20 to 100% based on the deodorant raw material.

[0004]

However, it has been found that the deodorant according to the above-mentioned inventions, etc., has a higher deodorizing effect when moisture is added to the deodorant, as compared with a state where no moisture is added, that is, a dry state. is doing. In other words, when the deodorant is not added with water, that is, in the dry state, the deodorizing effect is not sufficient. When using the product, the deodorant sheet itself is in a dry state, so until the moisture absorption at the installation site is sufficient,
The efficiency of deodorization is not the best. in this case,
If you try to quickly give moisture or humidity to the deodorant sheet, you may think that it will be soaked in water, but if you do so, it will be sick because it will drip water or will come into contact with other objects to get wet.
There was a problem.
