无机铝盐防水剂 水泥砂浆防潮粉膨胀剂 混凝土强吸附性防水粉批发

利用固体材料的吸附特性，采用表面处理技术，即将无机固体粉料为基材，加水配成料浆，当基材的*电位与离子型表面活性剂的电性不匹配时，调节粉料的*电位、使之与离子型表面活性剂电性相匹配，料浆与表面活性剂混合后，在0℃～100℃范围内以不超过30转/分的速度充分搅拌，使离子型表面活性剂被稳定地定向吸附在无机粉粒表面上，料浆经脱水干燥，干燥温度最高不超过160℃、且在干燥过程中先用低温0℃以上，以后可逐步提高，即得具有憎水性的建筑防水粉，其配比按基材：离子型表面活性剂：*电位调节剂：助剂=100∶0．2～10∶0～35∶0．01～1的重量比配料，因反应在溶液中进行，加水量以便于搅拌。
