Common Problems and Solutions for High-elastic Silicone Oil Products -- 2021-05-11

1. Coke core (the temperature of the reaction center exceeds the antioxidant temperature of the raw material)(1) The quality of polyether polyols is problematic: the moisture in the product exceeds the standard during the production, storage and transportation, the content of peroxides and low-boiling impurities is too high, the concentration of metal ions is too high, and the type and concentration of antioxidants are inappropriate;(2) Formula: In the low-density formula, the TDI index is too h ...

Foaming Agent-surfactant Principle of Action -- 2021-05-10

The surface activity of the foaming agent The foaming agent is a surfactant, and its surface and interface properties are important indicators. The surface tension and interfacial tension of the foaming agent should be measured first. Since the injected formation is a gas-liquid two-phase, it is necessary to measure the surface tension and interfacial tension of the mixed solution injected into the formation and the vapor-condensed aqueous solution. The measurement method may be carried out by t ...

Common Types and Advantages of Silicone Oil in Cosmetics -- 2021-05-06

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 ...

Types and Applications of Silicone Strippers -- 2021-04-30

Organosilicon compounds contain the Si-0 skeleton of silicon-oxygen bonds. All or-part of the silicon atoms are combined with organic groups, such as methyl and phenyl. The surface tension of organosilicon is very small. Adhesives are difficult to adhere to. Therefore, the paper industry takes advantage of this feature and uses organosilicon compounds as release agents to produce release paper. The organosilicon compound used in the peeling paper must meet the conditions of good peeling performa ...

Composition of High Temperature Resistant Silicone Oil -- 2021-04-29

Silicone oil is generally colorless (or light yellow), odorless, non-toxic, and non-volatile liquid. Silicone oil is insoluble in water, methanol, glycol and -ethoxyethanol. It is miscible with benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride or kerosene. It is slightly soluble in acetone, dioxane, ethanol and butanol . It has a small vapor pressure, a higher flash point and ignition point, and a lower freezing point. As the number of segments n is different, the molecular weig ...

Types and Chemical Structure and Properties of Siloxane -- 2021-04-28

There are many types of polysiloxanes, which are mainly divided into three categories according to the chemical structure and properties of the products:SiloxaneSiloxane (2 photos)①Silicone oil (modified silicone oil) is a low molecular weight (generally less than 10,000) linear structure polymer. In order to achieve certain properties, the molecular structure will also be grafted and modified. Colorless or light yellow transparent liquid, water-repellent and oil-repellent, with high boiling po ...

The Use Method and Principle of Polyurethane Foaming Agent -- 2021-04-27

Polyurethane foaming agent is the product of cross combination of aerosol technology and polyurethane foam technology. There are two kinds of spongy states in the pipe type and gun type. Styrofoam is used as a foaming agent for the production of microcellular foams. It can generally be divided into physical and chemical types. This is based on whether the production of gas is a physical process (that is, volatilization or sublimation) or a chemical process (that is, chemical structure). Damage o ...

How to Use Food Grade Defoamer -- 2021-04-26

Food products defoamers are mostly used in the food processing industry. They are only produced under the strict control of domestic food product silicon residues and strict control of various standards. In short, it can produce effective food processing It has defoaming and anti-foaming effects, but does not affect the taste and quality of food. It is a product that helps food improve the utility value.It has the unique advantages of not affecting the taste of the product, rapid defoaming, long ...
