The effect of plasticizers based on sulfonated melamine formaldehyde (Melment F 15 G) and polycarboxylate (Melflux 5581 F, Sika ViscoCrete-G2) on the properties of molding plaster consisting of α-calcium sulfate hemihydrate was studied. The concentrations of additives that increase the strength in compression of molding plaster samples by factor of 1.5 – 2 were determined on the basis of the results of this work.

添加的增塑剂对成型石膏强度指标的影响

研究了基于磺化三聚氰胺甲醛（M 15熔体）和聚羧酸盐（Melflux 5581 F，Sika ViscoCrete-G2）的增塑剂对由α-半水合硫酸钙组成的石膏灰浆性能的影响。根据这项工作的结果，确定了使模压石膏样品的压缩强度提高1.5-2的添加剂浓度。
