If the amount of clay powder in rubber is too much, will there be frosting?

Ding!! Shenzhen surrounding rubber seal manufacturers boss add a powder.

Rubber can hit people. Just look at One Piece.

What are you living for, and why do you exist?

Rubber is divided into natural rubber and synthetic DU rubber according to raw materials. Press the shape.

The zhi state is divided into lumpy raw rubber dao and latex.

Liquid rubber and powder rubber. Latex is a colloidal aqueous dispersion of rubber; Liquid rubber is an oligomer of rubber, which is generally a viscous liquid before vulcanization; Powder rubber is processed into powder form of latex to facilitate batching and processing. Thermoplastic rubber, developed in the 60s of the 20th century, is formed by the processing method of thermoplastics without chemical vulcanization.

Rubber is divided into two categories: general type and special type according to use. It is an insulator that does not easily conduct electricity, but it may become a conductor if it gets wet or has a different temperature. Conductivity is a condition that concerns the conduction of electrons of molecules or ions inside a substance.

Rubber is made from the latex of rubber trees, rubber grass and other plants, and is made into a material with elasticity, insulation, impermeability to water and air after processing. Highly elastic polymer compounds. It is divided into two types: natural rubber and synthetic rubber.

Natural rubber is made from rubber trees, rubber grass and other plants after extracting gum; Synthetic rubber is obtained by polymerization of various monomers.

Rubber is widely used in industry and life, and the rubber products industry is also diverse and has a wide range of uses.

Rubber: A highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under the action of small external force, and can return to its original state after removing external force.

Rubber is a completely amorphous polymer, and its glass transition temperature (tg) is low, and the molecular weight is often large, more than hundreds of thousands.

Ingredients: Natural rubber is made from latex, and some of the non-rubber components contained in the latex remain in the solid natural rubber. Generally, natural rubber contains 92%-95% of rubber hydrocarbons, while non-rubber hydrocarbons account for 5%-8%.

Due to different manufacturing methods, different origins and even different rubber picking seasons, the proportion of these ingredients may be different, but basically within the range.

Protein can promote the vulcanization of rubber and delay aging. On the other hand, protein has strong water absorption, which can cause moisture absorption and mildew of rubber, decreased insulation, and protein also has the disadvantage of increasing thermogenesis.

Acetone extract is a number of high-grade fatty acids and sterols, some of which act as natural antioxidants and accelerators, and some can help the powdered compounding agent disperse and soften the raw rubber during the mixing process.

The ash mainly contains salts such as magnesium phosphate and calcium phosphate, and there are very small amounts of metal compounds such as copper, manganese, iron, etc., because these valence metal ions can promote the aging of rubber, so their content should be controlled.

The moisture in the dry rubber does not exceed 1%, and it can be volatilized during processing, but when the moisture content is too much, it will not only make the raw rubber easy to mold during storage, but also affect the processing of rubber, such as the compounding agent is easy to agglomerate during mixing; It is easy to produce bubbles in the process of calendering and extrusion, and bubbles or sponges are produced in the process of vulcanization.

Rubber: a highly elastic polymer compound. It is divided into two categories: natural rubber and synthetic rubber. Natural rubber is processed from latex obtained from rubber trees; Synthetic rubber is made from monomers that are polymerized or polycondensed.

Unvulcanized rubber is commonly known as "raw rubber" or "raw rubber"; Vulcanized rubber is called "vulcanized rubber", also known as "cooked rubber" or "rubber". It is widely used in the manufacture of tires, hoses, tapes, rubber shoes, insulating materials, etc.

Rubber is divided into synthetic rubber and natural hot rubber according to the manufacturing method. Name implies.

Synthetic rubber is rubber that is polymerized into polymers with chemical monomers in --- factory. Natural rubber is mostly produced in tropical countries such as Hainan, Yunnan and Malaysia, Brazil, Thailand, Vietnam and other countries abroad;

Rubber is further divided into according to performance; Oil-resistant rubber, such as nitrile rubber, hydrogenated nitrile, neoprene, etc. Non-oil-resistant rubber such as natural rubber, butadiene rubber, butyl rubber, ethylene propylene rubber, etc.
