CT5-3是先由多元醇与脂肪酸在催化剂作用下经加热、酯化、脱水制成消泡主剂,然后再加入辅助消泡剂复配而成的。使用泥浆密度的恢复作为泥浆消泡剂消泡性能的评价方法。CT5-3在泥浆中的加量为0.1-0.3%,以0.2%为宜。该剂具有显著的消泡作用,有一定的抗盐、抗钙能力,润滑作用,并且还有性能稳定、不污染环境、加注方便等优点。 CT5-3 is the first by the polyol and fatty acids in the catalyst under the action of heating, esterification, dehydration defoaming made of the main agent, and then added auxiliary defoamer compound made. The use of mud density recovery as a defoamer antifoam defoaming performance evaluation method. The dosage of CT5-3 in mud is 0.1-0.3%, preferably 0.2%. The agent has significant defoaming effect, has certain salt resistance, calcium resistance, lubrication, and also has the advantages of stable performance, no environmental pollution, convenient filling and so on.
