What are the advantages of using silicone defoamers? After the defoamer was adopted by people, people soon found that the operation efficiency and operation quality of manufacturing enterprises were greatly improved due to the addition of defoamers. Of course, we can also call defoamers silicone defoamers. It is a kind of silicon-containing active medium. When…
The role of defoamers in sewage treatment The sewage defoamer is dispersed more evenly during use. It relies on non-ionic media to dilute the bubbles, thereby eliminating bubbles on a large scale. In this way, without bubbles, major manufacturers can operate normally and orderly. It can be seen that defoamers are very practical industrial liquids.…
Application of Defoaming Agent in Dyeing and Finishing Production During the production and processing of knitted fabric printing and dyeing, foaming causes the fabric to float on the water surface, and in severe cases, cloth blocking occurs (overflow jet dyeing machine). At this time, people often hope to use low-foaming surfactants to meet the needs…
Use of water treatment defoamer Water treatment polysiloxane defoamer – polysiloxane defoamer is usually composed of two main components, polydimethylsiloxane and silicon dioxide, which are properly matched. The defoamer based on polydimethylsiloxane is an ideal defoamer in the defoaming system because it is insoluble in water and difficult to emulsify. Polydimethylsiloxane has lower surface properties…
Common classification of defoamers I believe that everyone is familiar with defoamers, so do you know some of the applications and classifications of defoamers in life? The following editor will introduce the common classification of defoamers. Organic silicon defoamer Organic silicon defoamer is a chemical medium, and the topic of chemical medium has always been…
Powder coatings and defoamers A too wide molecular weight distribution means that there are resins with too small or too large molecular weights, which cannot be well integrated with other components of the coating. Under such conditions, when baked at high temperature, the miscibility between the coatings is poor, and the surface tension of the…
Defoaming mechanism and its influence on construction As the oil industry enters the middle and late stages of exploitation, oil and gas fields with high hydrogen sulfide and carbon dioxide content gradually emerge, and many oil fields have high water content, which puts forward higher performance requirements for the anti-corrosion of oil pipes. At present,…
Test methods for defoamer performance Common testing methods for defoamer performance and antifoam performance include: Ross-Myers method, West German Industrial Standard method, aeration method, stirring method, titration method, high-speed dispersion method and circulating bubbling method. The differences between these methods lie in the causes of foam generation, the timing of adding defoamers, and the static…
