METHOD OF MANUFACTURING INORGANIC PLATE

摘要

PROBLEM TO BE SOLVED: To improve durability such as water resistance, frost resistance and dimensional shrinkage resistance, without lowering physical properties such as strengthes, that an inorganic plate has. SOLUTION: An alkoxysilane having a 6-10C normal alkyl group or a water repelling agent containing the same as a main component is applied over the entire surface of a cement base inorganic plate and the surface of the plate is impregnated therewith.
