A METHOD OF PRODUCING AN INORGANIC MOLDED PRODUCT

摘要

The present invention provides. a method of compression- molding a slurry consisting of a hydraulic inorganic material such as cement or slag, a lightweight aggregate, a reinforced fiber material and other filler material kneaded with water so as to manufacture an inorganic molded product. The slurry is put into a molding frame having a filtering cloth placed over the bottom surface thereof and is then compression- molded in the molding frame by using a molding die while it is suction- dehydrated from on both sides of the molding die surface and the filtering cloth surface. The molding die has a number of vent holes for suckingdehydration each of which vent holes comprises a small- diameter hole and a largediameter hole continuous therewith.
