た。However, in such a conventional method for producing various inorganic moldings, the moldings obtained do not necessarily satisfy the high requirements of strength and water resistance. However, there is a problem that it is difficult to obtain a molded product having a complicated shape.

不充分であるという難点が生じる。That is, in the above-mentioned method for producing a wet inorganic molded body, the molar ratio (SiO 2 ) / (Na 2 O) of sodium silicate used as a binder is 2.0 to 3.7,
Since such a mixed material obtained by adding and kneading sodium silicate has extremely poor fluidity, when a molded product having a shape other than a simple flat panel is to be obtained, the mixed material is added in order to increase the packing density after usual molding. It takes time and effort to compact the material and disperse the material, and thus it takes extra time for the molding operation, and the resulting molded body has insufficient mechanical strength.

欠点を有している。In the dry method for producing an inorganic molded body, water glass and caustic soda are added to the inorganic material to adjust the molar ratio (SiO 2 ) / (Na 2 O) to less than 1.0. Has the advantage that it is dry and not plastic and does not require tamping work to increase the packing density after molding, but excess sodium in sodium silicate, which is the main component of water glass, significantly reduces water resistance. It has a drawback that it will end up.
