The scientific name of organosilicon is polysiloxane resin. In the polysiloxane molecule, the ratio of the organic substituent (R) to the silicon atom (Si) is an important parameter that determines the product form. When R/Si<2, the product is silicone resin; when R/Si≈2, it is a high viscous plastic state, namely silicone rubber; when R/Si>2, it is a low molecular weight oil, Called silicone oil.Performance parameter The explanations are as follows:Appearance: The external appearance of ...

Bubble powder brings various problems to industrial manufacturing: in order to prevent the bubble powder from overflowing, the feed index is reduced by 35%~55%; the bubble powder overflows and causes the waste of raw materials; the bubble powder takes up space and affects the reaction. Speed, the production period can’t help but extend the time; foam will affect the quality of products, such as textile coatings, plastic products; the formation of foam will affect the stability and reliability o ...

A substance that can make solid materials more easily wetted by water. By reducing its surface tension or interfacial tension, the water can spread on the surface of the solid material or penetrate the surface, thereby wetting the solid material.Wetting agent is a surface active agent that can make solid materials more easily wetted by water by reducing its surface energy.Such as sulfonated oils, soaps, pull open powder BX, etc., soy lecithin, mercaptans, hydrazides and mercaptan acetals, etc. c ...

Silicones The most commonly used is polydimethylsiloxane, also known as dimethyl silicone oil. It has low surface energy, low surface tension, low solubility in water and general oil, and high activity. Its main chain is a silicon-oxygen bond, which is a non-polar molecule. It has no affinity with polar solvent water, and has little affinity with general oils. It has low volatility and chemical inertness, relatively stable and low toxicity. Pure dimethiconeAlkane, it is difficult to be used as a ...

Paint wetting agents are divided into two types: substrate wetting agent and wetting dispersing agent. The substrate wetting agent is used to improve the surface tension and permeability of the coating, so that it can better wet the substrate, thereby improving Coating adhesion, especially for improving the adhesion of primers to substrates, is widely used, generally some fluorocarbon or fluorocarbon modified ionic or non-ionic substances or other substances that can improve the wetting of the s ...

Background technique:Agricultural aviation plant protection is the use of planes to spray pesticides or fertilizers to prevent and control diseases, pests, and weeds in farmland, forests, and grasslands or to manage field growth. During the aerial plant protection spraying process, since the spray volume per mu is 0.5-1.5L, the dilution concentration of pesticides is about 15 times higher than that of artificial or mechanical spraying on the ground. The demand for pesticide formulations and the ...

In the formulation, the main functions of surfactants are: one is to improve the emulsifying ability between the components, so that they can be more effectively mixed with each other; the other is to control the system to have proper surface tension during the foaming process to produce a good Bubble network structure, therefore, can also be called foam stabilizer. Polyester and polyether flexible foam have different raw material bases and different properties. Therefore, the selection and dosa ...

Whenever we agitate the liquid or be introduced into the gas, many bubbles will be generated inside the surface of the liquid, and some bubbles generated by the liquid will quickly break and disappear. Some liquids not only do not disappear, but also gather more and form bubbles. Foam is a dispersion system formed by a large number of bubbles dispersed in a liquid. The dispersed phase is gas and the continuous phase is liquid. Among them, the volume fraction of the foaming liquid is very small, ...

Defoamers can be divided into many types, including water-based defoamers and oil-based defoamers, so the question is, what is the difference between water-based defoamers and oil-based defoamers ? How to choose them? Let’s talk to the editor of Haian Petroleum!The price of water-based defoamers is relatively low, and they are widely used in textile printing and dyeing, pulping and papermaking, chemical reactions, petrochemicals, metalworking fluids, biological fermentation, water treatment and ...

Performance characteristicsThis product is a long-lasting anti-foaming polyether-modified silicone defoamer specially developed for use in harsh environments such as high temperature, high pressure, acid and alkali using imported raw materials. This product is made of polyether copolymer with strong hydrophilicity and long-lasting foam suppression and polysiloxane with strong hydrophobicity and rapid foam breaking as the main components. This product is different from general emulsion defoamers. ...
