Common problems and functions of defoaming agent during use At present, industrial production is developing very rapidly in society. In the production process, defoamers are often used to eliminate harmful foams. However, many manufacturers will encounter many problems when using defoamers. Let’s follow the editor to learn about it. 1. Turbidity of defoamer: Defoamers are…
Benefits of Silicone Defoamers In many industrial production fields, the use of some auxiliary agents also plays a very important role. Among them, silicone defoamer is a very common auxiliary agent. The following editor will introduce the benefits of silicone defoamer to you. 1. No side effects It can be said that no side effects…
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,…
What are the factors affecting the effectiveness of defoaming agents? Defoamers are very important for many industries, but many companies will encounter the reasons why the defoamer effect becomes worse when using defoamers. The following editor will introduce the factors that affect the use of defoamers. 1. Dispersibility of defoamers in solution The dispersion state…
The development of piston for defoamer After extensive market research and according to the actual needs of different manufacturers, Shantui Komatsu Lubricating Oil Company has developed a new type of cleaning agent based on the original metal cleaning agent. This product is mainly composed of high-quality surfactants, combined with a variety of inorganic additives, and…
Effect of Defoaming Masterbatch In order to eliminate the moisture in plastic raw materials, a newly developed functional plastic masterbatch – defoaming masterbatch has brought a new way to solve the moisture problem in plastic raw materials. The plastic masterbatch defoaming masterbatch can adjust the addition ratio according to the moisture content of the raw…
Test methods for defoamer performance Common test 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, etc. Some other methods such as ASTM D892-06e1 standard, ASTM-E2407-04, oscillation method (or shake bottle method), Goschmidt evaluation method, Q/XGY014-91…
