摘要
以磷石膏基α型高强石膏为原料,采用自制磷石膏专用发泡剂物理发泡,分别使用不同类型、规格、用量的纤维以改善磷石膏基α型高强石膏发泡材料的力学性能.研究表明,12mm的聚酯纤维用量0.4％,先在水中充分分散,再加入预混0.01％蛋白类混凝剂的α高强石膏,控制泡沫加入量,制成干密度为(340±10)kg/m3的α型高强石膏发泡材料,可使发泡材料的抗折强度显著提升.
Abstract
Using phosphogypsum-based α-type high-strength gypsum as raw material,the physical foaming agent for phosphogypsum is used to improve the mechanical properties of phosphogypsum based α-type high-strength gypsum foam material with different types,specifications and amounts of fibers.The research shows that the bending strength of foam can be significantly improved when the dosage of 12 mm polyester fiber is 0.4％,the polyester fiber is fully dispersed in water,and then the a high-strength gypsum premixed with 0.01％protein coagulant is added to control the amount of foam added,and the α-type high-strength gypsum with a dry density of(340±10)kg/m3 is obtained.
