此类消泡剂的研究主要是在高温下将矿物油和疏水粒子混合，使疏水粒子分散其

Study of such defoamer mainly mineral oil and hydrophobic particles are mixed at elevated temperature, wherein the hydrophobic particles are dispersed, after the "secondary aggregate" and "primary aggregates", followed by addition of an emulsifier obtained at lower temperatures. Qin et hop pool was prepared using a mineral oil defoamer mineral oils, fatty acid amides, fatty acid metal soaps, antifoaming aids, and other raw materials of silica and an emulsifier. Wherein the fatty acid amide, fatty acid metal soap and silica as the defoaming material, a method by mixing various mineral oil defoaming substance changes the defoamer defoaming performance and stability can be improved. This type of mineral oil defoamers in coatings, paper and other industries have very good prospects.

The study of such defoamers is mainly to mix mineral oil sprigs with hydrophobic particles at high temperatures, so that hydrophobic particles are dispersed, through "secondary aggregation" and "one-time aggregation", and then added to emulsifiers at lower temperatures. Pool Yueceler and other raw materials such as mineral oil, fatty acid amide, fatty acid metal soap, defoaming aids, white carbon black and emulsifier stoking agent to prepare a mineral oil defoaming agent. Among them, fatty acid amide, fatty acid metal soap and white carbon black are defoaming substances, which improve the defoaming performance and stability of defoaming agents by changing the mixing method serotonin in mineral oil. This mineral oil-type defoaming agent in the coating, paper and other industries have a good application prospects.

This kind of defoamer is mainly made by mixing mineral oil and hydrophobic particles at high temperature, dispersing hydrophobic particles, and then adding emulsifier at low temperature. Chiyueqin and other raw materials such as mineral oil, fatty acid amide, fatty acid metal soap, defoamer, silica and emulsifier were used to prepare a defoamer for mineral oil. Among them, fatty acid amide, fatty acid metal soap and white carbon black are defoamers. By changing the mixing method of various Defoamers in mineral oil, the defoamer performance and stability can be improved. This kind of mineral oil defoamer has a good application prospect in coating, papermaking and other industries.<br>
