Defoamer reaction after stirring At present, in addition to the use of cathodic protection and corrosion inhibitors to provide anti-corrosion protection for oil pipes, coatings are gradually accepted by people due to their economy and effectiveness, and have become one of the effective ways to prevent pipe corrosion. Since bubbles are easily generated during the…
Research on Defoaming Additives For architectural coatings, defoamers must combine with a stable surfactant layer and penetrate into the bubble membrane bimolecular membrane. After contacting the bubble, it spreads rapidly to form a very thin bimolecular layer. As the defoamer further spreads and invades, it replaces the membrane wall of the original foam. Because liquids…
How to choose a defoamer suitable for sewage treatment Whether it is a factory or a sewage treatment plant, the sewage treatment process will inevitably produce a lot of foam, and foam pollution is also a kind of pollution that cannot be ignored. Therefore, most sewage treatment companies also know how to add sewage treatment…
Five advantages of desulfurization and defoaming agents for power plants 1. Excellent stability When the salt concentration and amine treatment in the glycol dehydration unit reach the highest level, the desulfurization defoamer will be very stable. 2. High efficiency performance The addition of desulfurization defoamers not only eliminates foam, but also increases the liquid transfer…
Uncover the application of cement defoamer in construction In modern urban life, high-rise buildings are built from the ground. They need to lay a good foundation and build up layer by layer. Cement plays an important role in this building. Among the cement additives, there is something that can keep the cement flat after hardening,…
Six inspection methods for defoamers for coatings After the foaming agent manufacturer produces the defoamer for coatings, in order to ensure the product quality, it is necessary to test the performance. The following six inspection methods can be used: 1. Cylinder method: Add an appropriate amount of low-viscosity coating into the cylinder, then add the…
The role of defoaming agent in drying equipment For architectural coatings, the defoamer must combine with the stable surfactant layer and penetrate into the bubble film bimolecular film. After contacting the bubble, it spreads rapidly to form a very thin double film layer. As the defoamer further spreads and penetrates, it replaces the original foam…
Defoaming agent for bubble control In the consumption of architectural coatings, due to the presence of additives such as emulsifiers, dispersants and thickeners in the formula, not only a large number of bubbles will be generated, but also the bubbles can be stabilized, resulting in a large number of bubbles in architectural coatings. In the…
