近年来,随着建筑工程的发展,高层及大跨度建筑迅速兴起,尤其在软上或沙层地基上建造房屋,迫切需要大量优质价廉的轻质隔墙材料,以降低建筑物重量及造价,缩短工期,并提高建筑物使用功能。石膏建筑制品具有轻质、高强、防火等优点,但天然一级熟石膏价格昂贵,而大量廉价低等级熟石膏、化学废石膏、废泡沫塑料等却堆积如山,
In recent years, with the development of construction projects, high-rise buildings and large-span buildings have risen rapidly. Especially building houses on soft or sandy foundations requires a lot of inexpensive lightweight partition materials to reduce the weight and cost of buildings. , shorten the construction period and improve the use of the building. Gypsum building products have the advantages of light weight, high strength and fire resistance, but natural first-class plasters are expensive, and a large number of cheap low-grade plasters, chemical waste plasters, and waste foams are piled up.
