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 ...

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 ...

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 ...

my country's glass fiber industry is a sunrise industry, and with the development of application fields such as construction, machinery, electronics and other glass fiber reinforced composite materials, my country's glass fiber industry is entering a new round of rapid development. It is estimated that during the "Eleventh Five-Year Plan" period, the growth rate of glass fiber production will be close to 10%. In 2010, my country's glass fiber production is expected to reach 1.3 million ...

Silicone pressure-sensitive adhesive is a special adhesive composed of silicone resin (commonly used MQ silicone resin), silicone rubber, catalyst, crosslinking agent and other additives. Silicone pressure-sensitive adhesives mainly include solvent type, high solid content type, solvent-free type, emulsion type, radiation curing type, resin modification type, biodegradable type, functional type and other systems.Since the solvent type contains a large amount of volatile organic compounds, during ...

Silicone glue is a kind of ointment, once exposed to moisture in the air, it will solidify into a tough rubber-like solid material. It is mainly divided into de-acetic acid type, de-alcohol type, de-ammonia type, and de-C type. Silicone glue is commonly called glass glue because it is often used for bonding and sealing of glass. One-component silicone glass glue is a kind of ointment, once it comes into contact with moisture in the air, it will solidify into a tough rubber-like solid material.Si ...

Commonly used foam agents and foam stabilizers are theseThey make the pores fine and uniform. When the system is in the low viscosity stage, it stabilizes the pore wall/the pores can grow to a thickness suitable for the opening, creating conditions for the final opening. The type of foam is different, and the type of stabilizer used is also; at the same time, its main function is to nucleate and emulsify each component in the formula. The compatibility of the various components in the foam formu ...

The leveling principle of silicone leveling agent: surface tension is the main driving force for the leveling of the coating film, but the poor surface tension is the main source of the surface defects of the coating film. Improve the surface tension of the coating film to achieve a balance of surface tension, which is very beneficial to the flow and leveling of the coating film, but it cannot be done. Therefore, people have to reduce the surface tension of the coating film to eliminate the diff ...

Application and selection of defoamers for water-based coatings. The water-based paint defoamer is a composite product of organic polyether ester, mineral oil, and alcohol. It will not produce surface defects or affect the film-forming properties, and has a special effect on the water-based paint system.product manualUsing water instead of organic thorns to prepare paint is safe, inexpensive and hygienic. After the emergence of synthetic resins, water-based coatings developed rapidly. Water-base ...
