METHOD AND DEVICE FOR MANUFACTURE OF CEMENT PLATE MATERIAL

摘要

PROBLEM TO BE SOLVED: To carry out the defoaming from a fast-setting cement plate material. SOLUTION: A fast-setting cement composition containing at least cement, water and a filler is continuously kneaded, and then the fast-setting cement composition is spread on a molding carrier belt 23 and continuously molded into a plate-shaped molded body in a cement plate manufacturing method, and the tapping operation for providing the amplitude in the up and down direction to the carrier belt 23 from below by a rod 20b of a cylinder device 20 is applied, an the fast-setting cement composition is defoamed before being cured.
