場所での使用ができ危いという問題点を有している。However, in the case of coatings formed from potassium silicate or sodium silicate, there are problems such as poor moisture resistance, reaction with carbon dioxide gas and '5Itite acid gas in the air, and efflorescence of the surface. However, since it has poor water resistance, it is dangerous to use it in places exposed to water.

る郷の問題点を有している。As a method to improve the moisture resistance and water resistance of a film that has deteriorated from alkali metal silicate, Alkali 4-Magkei FJJ! A method has been proposed in which the film of i is left in a humid atmosphere containing at least seven gases selected from the group consisting of sulfurous gas, carbon dioxide, and nitrogen dioxide, and then washed with water. According to the 6# method (Japanese Unexamined Patent Publication No. 13-413144!), an improvement in IL+aqueous property can be expected;
If the film is corroded by acid gas and water, or if the alkali content is insufficiently neutralized by the 11-group gas, the film will devitrify when washed with water, and the acid gas will remove the necessary amount of alkali from the vitreous film. Neutralizing the enemy is difficult and difficult, and has problems that require a long time.

It is expressed by the formula %"081%, and the larger n is, the better the water resistance is, but if n is 9 or more, it will remain in an aqueous solution state and become useless as a test forming agent. Although it is not a turtle, it takes advantage of the fact that by including the Li2Q component, the state of an aqueous solution can be maintained even if n is arbitrarily changed. n1tjt in the general formula is also an important component. The requirements are sharp, and q≦n(/θfL<
