介绍应用最广泛的可再分散乳胶粉－醋酸乙烯－乙烯共聚物粉料.水泥与可再分散乳胶粉组成理想的粘结体系,它的掺入可提高水泥砂浆的抗压强度、与其它基材的粘结强度、增加塑性和提高抗弯强度.由于它是单一体系,使用方便,并可大大减少运输、贮存、包装费用.列出了实验资料,以说明可再分散乳胶粉与水泥砂浆之间的相互关系,还介绍了一些典型应用.“,”The whole introduces the redispersable powder - vinyl acetate - vinyl copolymer powder which has been widely used.The ideal gluing system consisting of cement and redispersable powder may increase the compression strength, the adhesive stengthmith other he material, the plasticity and the bending strength of the cement. It is a single system with easily application and greatly reduceing the costs for transportation , stoop and package. The experimental data have been listed so as to explain the mutual relationship between the redispersable powder and cement mortar. Some typical applications have the ho presented.
