When the air enters the liquid containing surfactant, under the action of external force, the surfactant will be aligned at the gas-liquid interface. The hydrophobic group is toward the air of bubble,......
2020-01-06There are many factors that affect the foaming and foam stabilization in the formulation of antifoam. 1: The surface tension of the ......
2020-01-061: Before use, it must be fully stirred and evenly mixed. 2: Add defoamer when the paint is stirred. &nb......
2020-01-06Quincke, a German experimental physicist, first proposed chemical methods for defoaming. In the 19th century, the colloidal chemist J.P. A Japanese colloidal chemist, hengtaka sasaki, began studying b......
2020-01-03General organic compounds such as ether, hydrocarbons, alcohols and phosphate esters, the spread coefficient is large, so the role of breaking bubbles is strong, but the role of bubble suppression is ......
2020-01-03Pure organosilicon, such as dimethyl silicone oil, has no defoaming effect. However, after emulsifying, the surface tension decreases rapidly, and the use of a very small amount can achieve strong ant......
2020-01-03Polyether modified organosilicon is a polyether - siloxane copolymer (abbreviated as silica ether copolymer) produced by introducing polyether chain segments into siloxane molecules. It is a kind of d......
2020-01-031. Add before foamingThis method can inhibit the production of foam by adding antifoaming agent to the system that may produce foam in advance. For closed container and device, defoaming agent can eff......
2020-01-03First stage defoamer: it is mainly composed of various organic substances, such as fatty acid, mineral oil, fatty amide, low alcohol, etc. Most of the defoamers are natural substances, which cause lit......
2020-01-02The antifoaming or antifoaming ability of organosilicon is due to its low surface tension. Silicone compound (silicone oil) interferes with the surface tension of gas-liquid interface, resulting in de......

2020-01-02Wide application: due to the special chemical structure of silicone oil, it is neither soluble with water or substances containing polar groups, nor with hydrocarbons or organic substances containing ......
2020-01-02First, the emulsion should be fully mixed before use. Because the uneven emulsion will easily produce stratification, affecting the use of defoamer. &nbs......
2020-01-02Organosilicon defoamer is widely used in many fields, such as glutamic acid, lysine and so on. It is also used in textile, printing and dyeing, coating, dyestuff, papermaking, ink, oil field, sewage t......
2020-01-02In the use of defoaming agent in the process, how many will encounter defoaming agent need to open dilute, open dilute will use thickening agent, so how to choose the right thickening agent?First, goo......
