摘要
利用油脂在碱性条件下发生皂化反应的原理,考察了溶剂用量、碱用量及油脂种类对水泥浆体触变性的影响,并且开发了适用于水泥浆体系的新型脂肪酸盐类触变剂,同时测试了触变水泥浆体的流变特性及不同时间段的扭矩.结果表明:掺入新型触变剂的水泥浆体具有良好的触变性,当浆体静置时,状态稳定;当以特殊剪切力搅拌浆体时,状态为流体状,流动度十分稳定.
Using the principle of saponification reaction, a new fatty acid salt thixotropic agent was devel- oped by investigating the effects of solvent content, alkali content and kinds of oils and fats on the thixo- tropic of cement paste. The rheological properties and constant torque in different periods were tested. The result shows that, the cement paste has outstanding thixotropy when incorporating new thixotropie agent. The cement paste is in relatively steady state when it is allowed to stand, but when a special shear stirs the cement paste, it is in a fluid-like state. The fluidity of cement paste is very stable.
