摘要
研究了外涂憎水剂、内掺憎水剂以及外涂-内掺复合处理3种处理方法对玻化微珠保温砂浆性能的影响。研究表明:外涂憎水剂处理后,在保温砂浆表面形成一层憎水膜,表面不会被水润湿;内掺憎水剂,保温砂浆的吸水率随着憎水剂掺量的增加而降低;外涂-内掺复合处理对保温砂浆的憎水性能改善效果更显著。
Three kinds of measures to improve hydrophobicity of thermal insulation mortar containing vitrified microsphere were presented as follows, brushing liquid hydrophobic agent on the surface of thermal insulation mortar, adding powdery hydrophobic agent to thermal insulation mortar and the composite methods.The results show that brushing liquid hydrophobie agent leads to formation of protective adsorbed hydrophobic film on the surface of thermal insulation mortar.The volume water absorption rate decreased due to the adding of powdery hydrophobic agent.The composite methods have better effect.
