In order to overcome the above shortcomings, the commonly used method is to modify its chemical structure. Modification methods include acylation modification, epoxy compound modification, formation of quaternary ammonium salt, etc. Organic silicon quaternary ammonium salt makes the nitrogen atom positively charged When used in fabric treatment to reduce oxidized energy and prevent yellowing, organosilicon quaternary ammonium salts are combined with fibers in two ways: one is that the positive c ...

According to the composition of the defoamer, it can be divided into many types, such as silicone defoamer, polyether defoamer, silicone polyether defoamer, mineral oil defoamer, tributyl phosphate defoamer, silicon Oxyane defoamer, n-butanol defoamer, etc. These are relatively common defoamers, and there are some uncommon ones, so I won't introduce them.If it is divided by industry, there are even more. Each industry has corresponding defoamers, such as water treatment defoamers, paper defoamer ...

my country's herbicide industry has grown from scratch, from small to large, and has gradually developed, and has now formed a complete industrial system. In more than 60 years, my country's herbicide industry has gone through a long process from quotation to introduction, from imitation to creation. According to statistics, since the implementation of pesticide registration in my country in 1982, nearly 200 herbicide varieties (active ingredients) have been registered by the Ministry of Agricul ...

Properties and types of silicone adhesivesBasic properties of silicone adhesives Silicone adhesives have unique heat and low temperature resistance, good electrical properties and weather resistance, chemical stability, hydrophobic moisture resistance, oxidation resistance, workability, sealability, breathability The electrical properties change very little in a wide temperature range, and the dielectric loss is low. It can be made into high-grade sealing material, mainly used for sealing bondin ...

Dear customers:The Spring Festival holiday in 2022 is approaching. According to the relevant regulations of the state and the company's actual situation and work arrangements, the Spring Festival holiday time is hereby notified as follows:From January 28th to February 7th, the construction will officially start on February 8th.I wish you all have a happy new year!Reminder: During the holiday, our company is not on duty, please deal with the problem in time.

Because there is relatively stable molecular structure Si-O-Si similar to inorganic acid salt in silicone polycondensate, no matter it is liquid, solid or elastomer polymer, it has high heat resistance and chemical stability. , Excellent electrical insulation and very good hydrophobicity.1) High temperature resistanceGenerally, the heat-resistant temperature of synthetic resin paint is below 150°C, while silicone paint can be used for a long time at 200°C. If high-temperature pigments are adde ...

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 ...

Silicone oil, as a common ingredient in cosmetics and skin care products, has a "false slippery" effect compared to hair care products. There are more types of silicone oil in cosmetics and skin care products, and its effects on the skin are also more amazing.About Silicone OilSilicone oil is also translated as silicium, because its structure is stable, non-toxic, not prone to degradation and not prone to chemical reaction with other products, so it is now more and more used in various ...

Curing is usually accomplished by condensation of silanols to form siloxanes. When the condensation reaction is in progress, due to the gradual decrease of the silanol concentration, the steric hindrance is increased, and the fluidity is poor, resulting in a decrease in the reaction rate. Therefore, in order to fully cure the resin, the reaction must be accelerated by heating and adding a catalyst. Many substances can catalyze the silanol condensation reaction, including acids and bases, soluble ...
