石膏纸浆纤维板是国外研制出的一种新型建筑材料,近年来在欧洲各国得到推广应用。这种石膏板是利用柔软的纸浆纤维作增强材料,与熟石膏配料而制成。1 生产工艺 目前石膏纸浆纤维板主要采用2种工艺即干法与半干法生产,但干法在国外应用较普遍。 干法工艺:干混合—成型—喷水—压实—养护—干燥—成品。 半干法工艺:干混合—加水半干法混合—成型—喷水—压实—养护—干燥。
Gypsum pulp fiberboard is a new type of building material developed abroad and has been popularized and applied in various countries in Europe in recent years. The gypsum board is made of soft pulp fibers as a reinforcing material, and a plaster composition. 1 Production Process At present, gypsum pulp fiberboard mainly uses two kinds of processes, dry and semi-dry, but the dry method is widely used in foreign countries. Dry process: dry mixing - molding - water - compaction - curing - drying - finished products. Semi-dry process: dry mixing - add water, semi-dry mixing - molding - water spray - compaction - curing - drying.
