FINE FINISHING METHOD FOR CEMENTITIOUS MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a fine finishing method for continuously manufacturing cement moldings having inorganic coloring finished surfaces without delamination in a manufacturing line. SOLUTION: The fine finishing method for the cementitious molded goods has a first process step for applying and penetrating an aqueous solution of a colorable metal salt compound on the surfaces of the cementitious molded goods regulated to a surface temperature 40 to 90 deg.C and a surface moisture content <=10 wt.%, a second process step of applying and penetrating a weakly alkaline liquid of 7<; pH <=10 to the surfaces of the cementitious molded goods by regulating the surface temperature of the cementitious molded goods to 40 to 90 deg.C and the surface moisture content to <=10 wt.% and a third process step of accelerating reaction by regulating the surface temperature of the cementitious molded goods to 40 to 90 deg.C and the surface moisture content to <=10 wt.%.
