METHOD FOR MANUFACTURING LOESS TILE

摘要

A method for manufacturing a loess tile is provided to obtain a loess tile having advantages in strength, water-resistance and storage. A method for manufacturing a loess tile comprises the steps of: (a) preparing an aqueous polymer solution containing complete-saponifiable(having a saponification of 98% or more) polyvinyl alcohol having a polymerization of 1,700 or medium-saponifiable polyvinyl alcohol having a polymerization of 2,400 in an amount of 5 wt%; kneading purified loess powders by adding the aqueous polymer solution of the step (a); (c) molding the paste obtained in the step (b) into a shape of tile by introducing into a mold and applying a pressure thereonto; and (d) drying a molded article obtained in the step (c) in the well-ventilated shade.
