Characteristics of silica gel for gypsum products①Gypsum products silica gel should have good operation performance.②Silicone has better fluidity, low viscosity and easy operation.③The smaller the shrinkage rate of silicone rubber, the better.④The tensile force of silicone rubber is better.⑤The made silicone mold cannot be deformed.⑥The hardness of silicone rubber should be suitable for product use.⑦High temperature resistance, many times of mold turning, the longer the service life, the ...

 Self-drying silicone resin for coating1. Specifications and modelsThis product is high temperature resistant self-drying silicone resin CG862, a benzyl silicone resin solution.2. Product performanceThis product is self-drying under normal temperature conditions and has good self-drying properties. This is particularly advantageous for the preparation of self-drying coatings for large equipment and workpieces that cannot be baked, and can be continuously produced on a large scale. Even if b ...

(1) According to paint componentsSilicone resin coatings can be divided into pure organic resin coatings and modified silicone resin coatings.Pure silicone paint is formed by dissolving pure silicone resin in xylene. It has good heat resistance, weather resistance, corrosion resistance, and insulation, but it has poor mechanical strength, adhesion and long drying time. But it can be modified with other resins to improve it. Representative varieties are W30-11 and W30-12.Modified silicone resin c ...

Silicone surfactants are a new type of adjuvant, which occupies an important position in the national economy and modern industrial and agricultural production. Through a review of the application of silicone surfactants in the field of pesticides, daily chemicals and the textile industry, The development prospects are prospected, and the main development directions of specialization, specialization, green and high-efficiency silicone surfactants are proposed.Silicone surfactants are a large cla ...

Background technique:Cosmetics and skin care products are commonly used products for modern women. Appropriate makeup can help women have a better appearance and vitality, and enhance their self-confidence. There are many types of cosmetics, which can be classified according to the object of use or the part of use, or according to the production process. At present, the current cosmetics production license in my country is classified according to the latter, which is divided into general liquid ...

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 the 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). Dama ...

Defoaming mechanism1. The decrease of the local surface tension of the foam leads to the collapse of the foamThe origin of this mechanism is to sprinkle higher alcohol or vegetable oil on the foam. When it dissolves into the foam liquid, it will significantly reduce the surface tension there. Because these substances are generally less soluble in water, the reduction of surface tension is limited to the part of the foam, and the surface tension around the foam hardly changes. The part with reduc ...

The role of active ingredients: foam breaking, defoaming, reducing surface tension: Representatives: silicone oil, polyethers, higher alcohols, mineral oils, vegetable oils, etc. [1] (2) Emulsifier function: Disperse the active ingredients into small particles, which are easy to disperse in water, and have better defoaming and anti-foaming effects. Representative: non(octyl)phenol polyoxyethylene ether, soap salt, op series, Tween series, Span series, etc. (3) Carrier function: Conducive to the ...

When it interacts with the substrate, it releases ethanol and combines with the substrate to convert it into a silicone resin polymer, and finally forms a hydrophobic silicone resin film on the surface of the pores of the substrate to prevent water and harmful ions from penetrating The inside of the base material achieves the purpose of waterproof protection, improves the strength of building materials, prolongs the service life of the building, reduces the maintenance cost of the building, and ...

The function of the raising agent is to make the fabric soft and fluffy, and it is easy to raise the fabric when it is processed by the raising machine. Some modified silicone oils and water-dispersible polyester derivatives can all be used as raising agents.The fabric passes through a series of raising rollers covered with steel wire card clothing. The needle points of the metal card clothing pick up the fibers in the weft yarn of the fabric and generate fluff after being hooked. These raising ...
