Classification and Market Development of Water-based Coatings -- 2021-04-09

Any paint that uses water as a solvent or as a dispersion medium can be called a water-based paint. According to the type of binder in the paint, water-based paints are divided into two categories: natural water-based paints made of natural substances or minerals (such as potassium silicate) and petrochemical water-based paints made of synthetic resins (such as acrylic resins). Only the water-based paint of artificial synthetic resin is described here.Water-based paint includes three types: wate ...

The Role of Defoamers in Industrial Applications -- 2021-04-08

In many inks and coatings processing production process, the need to use surface-active substances to achieve special effects. For example, in the production of water-based paint, water-insoluble base material production, water-insoluble base material is required to deal with the use of emulsifiers. At the same time, we have to improve substrate wetting and coating pigment dispersion by using additives.Surfactant most important characteristic is that they have a tendency to build in the interfac ...

Instructions for Use of Silicone Waterproofing Agent and Principle of Waterproofing -- 2021-04-02

One. Product name Potassium methyl silicateTwo. Product introduction:This product needs to be diluted with water when used. It is used for the treatment of materials such as stone and bricks, ceramics, cement mortar, perlite, gypsum and fiber gypsum board, especially porous materials, which can produce surface waterproof and reduce water absorption. It is permeable and absorbable, and can maintain the natural appearance of the substrate without changing the original color and appearance of the s ...

One: What can be used as a cleaning agent for silicone oil?Of course it is a silicone oil cleaning agent, as I have already said. Mainly used in clean clothes, nitrile gloves, rubber gloves, FPC circuit boards, precision electronic components, etc., with good cleaning and anti-rust effects.Two: the principle of silicone oil cleaning agentSilicone oil cleaning agent is a water-polyol-based mixture accurately synthesized by high-quality anionic and non-ionic surfactants to produce a near neutral c ...

Hydrophobicity and Mold Release of Silicone Oil -- 2021-03-31

Silicone oil has very good hydrophobicity. The so-called hydrophobicity means that the water in the liquid phase only wets the silicone oil/air interface to a lesser extent. The size of the contact angle formed by the water droplets placed on the surface with the surface is a measure of the hydrophobicity of the surface. If the contact angle θ is greater than 90°, the hydrophobicity is better, and the contact angle θ is less than 90°, which indicates that the water is poor.The surface hydrop ...

Description of Raw Materials Used in Coupling Agent -- 2021-03-30

1 Trichlorosilane:Trichlorosilane is an important intermediate for the synthesis of organic silicon, and it is also the main raw material for the preparation of semiconductor-grade polysilicon and solar cell-grade polysilicon. For a long time, due to the small production capacity of polysilicon in my country, trichlorosilane is mainly used for silicone rubber coupling agents and other organic silicon materials, and the amount of polysilicon is very small.Trichlorosilane process technology plan:① ...

Features of glue defoamer -- 2021-03-26

The oil-based glue defoamer is made of ether, fatty alcohol and multiple active additives through a special process. It is easy to disperse in water-based system, has strong self-emulsification, good defoaming, long-lasting foam suppression, and has special effects on water-soluble polymers and medium- and low-viscosity systems. It is especially suitable for latex-type water such as styrene-acrylic, ethylene-propylene, pure acrylic, vinyl acetate emulsion, and carboxyl butyl styrene. It has the ...

Synthesis of Silicone Resin and Its Application in Hair Cosmetics -- 2021-03-23

Hair structureHair grows in simple hair follicles, and the part above the skin surface is called the hair shaft, and the part inside the hair follicle is the hair root. There are hair bulbs connected to the lower part of the hair follicle at the lower end of the hair root. The concave part of the lower end of the hair bulb is called the hair papilla. There are connective tissues, nerve endings and capillaries in the dermal papilla, which play a vital role in the growth of hair. The upper part of ...
