The working principle of silicone additives -- 2018-01-29

In the material to add, play a supporting role of organic silicon compounds, known as the silicone additives. Its working principle depends on the type of additives, the role of. Such as silane coupling agent, added to the adhesive to increase the bonding strength of the role. The principle is that the silicon alkoxide in the coupling agent molecule can undergo a dealcoholization reaction with hydroxyl groups on the surface of the substrate to be bonded to form a chemical bond and the other end ...

The principle of foaming and defoaming agents -- 2018-01-26

Whenever we agitate the liquid or pass the gas, a lot of bubbles are generated inside the surface area of ​​the liquid, and some bubbles generated by the liquid quickly crumble and disappear. Some liquid not only does not disappear, but the more the more gathered to form a bubble. Foam is a dispersed system with a large number of bubbles dispersed in a liquid. The dispersed phase is a gas and the continuous phase is a liquid. The volume fraction of bubbling liquid is very small, foam occupies ...

The advantages of silicone defoamers -- 2018-01-17

The advantages of silicone defoamers(1) Wide range of applications: Due to the special chemical structure of silicone oil, it is neither compatible with water or polar group-containing substances nor with hydrocarbon or hydrocarbon-containing organic matter. Due to the insoluble nature of silicone oil, which is widely used, both water system defoaming, but also in the oil system.(2) small surface tension: the surface power of silicone oil is generally 20-21 dyne / cm, than the water (72 dyne / c ...

The role of silicone oil shampoo -- 2018-01-16

What is silicone-free shampoo? Broadly speaking, the shampoo composition table does not contain silicone oil: polydimethylsiloxane, polydimethylsiloxane alcohol, amino-terminated polydimethylsiloxane and other ingredients of the product can be called silicone-free shampoo . Conversely, shampoos containing the above ingredients are silicone shampoos. Non-toxic silicone oil is recognized, it can be used for care products, and for many years has become a mainstream additive, the role must not be ig ...

Characteristics of Silicone Oil and Its Application in Cosmetics -- 2018-01-15

Silicone oils commonly used in various cosmetic formulations include: polydimethylsiloxane, polymethylphenylsiloxane, polydimethylcyclosiloxane, silicone glycol copolymers, amine groups Modified silicone oil, polysiloxane protein copolymer and emulsified silicone oil. Silicone oil is widely used in creams, lotions, face creams, mousses, styling hairsprays, lipsticks, vermicelli, wet and dry powder, fatliquor and shampoos, based on the lubricity, breathability and silky feel of silicone oil , Con ...

Coating and has moisture resistanceWet, acid and alkali resistance, radiation resistance, ozone resistance, corona resistance, flame resista ...

Defoamer principle and use -- 2018-01-11

In the process of industrial production, if a large number of bubbles exist, it will bring a lot of troubles to the production process, for example, the production capacity will be greatly restricted; the waste of raw materials and products will be caused; the quality of products will be affected; the environment will be polluted, So if it can not be properly resolved, it is no exaggeration to say that the "bubble" will become our stumbling block and become a "bottleneck" in ...

Polyether modified silicone -- 2018-01-10

Polyether modified silicone, polyether segment is introduced into the siloxane molecules obtained polyether - siloxane copolymer (referred to as silicone ether copolymer). Polyether modified silicone defoamer is the combination of the advantages of both a new type of highly efficient defoamer. It is the choice of polyether with strong anti-foam ability and strong hydrophobic, rapid breaking silicone oil as the main component, matching silicone oil and polyether can be combined with emulsifiers, ...
