Q:The action of various ingredients in rubber formula

Cost system: filler, compatibilizer

Q:What does the rubber tire do to people?

Rubber is divided into natural rubber and synthetic rubber according to its raw material. According to the form is divided into block rubber, latex, liquid rubber and rubber powder. Latex as a rubber colloidal water dispersion; liquid rubber as an oligomer of rubber, not before the vulcanization is generally viscous liquid; powder rubber is the latex processing into powder, in order to benefit ingredients and processing. Thermoplastic rubber, developed in 1960s, does not require chemical vulcanization and is shaped by thermoplastic processing. Rubber according to the use of divided into general and special type of two categories. It is not easy to insulator, conductive, but if water or different temperature, are likely to become a conductor. Conduction is the conduction of electrons in a substance, molecule, or ion.

Q:How long is the warranty period for EPDM?

Rubber product (rubber products) refers to the natural and synthetic rubber as raw material to produce all kinds of rubber products activities, including the use of waste rubber reproduction of rubber products.

Q:What are the causes of chapped rubber products?

Rubber aging is a common problem of rubber products, and aging is mainly due to internal structure or component is easy to aging due to weakness, such as unsaturated double bond, branched, carbonyl, hydroxyl and so on; at the end, the main external or environmental factors are sunlight, oxygen, ozone, heat, water and mechanical stress force, high energy radiation, electricity, industrial gas, water, salt fog, fungi, bacteria, insects etc.

Q:What are the hazards of rubber accelerators?

Many have carcinogenic substances, long-term contacts are not too good, attention to protection is also necessary.

Q:What is the role of softening plasticizers in rubber? How are they classified?

The plasticization of rubber can be done in a physical and chemical manner. The chemical plasticizer including the plasticizing plasticizing plasticizing process, which belongs to the rubber processing, internal plasticization in synthetic rubber, through the chemical reaction on the rubber chains into molecular structure flexibility, plasticity to achieve. Chemical plasticization will not be lost because of the volatilization or precipitation of plasticizing substances, and the plasticizing effect is long. Therefore, more and more attention has been paid to it. Physical plasticization refers to the purpose of increasing plasticity by means of additional substances. The term "plasticization" is usually referred to as physical plasticization, and the added substance in physical plasticization is called softening plasticizer.

Q:Half finished rubber film surface white is going on

Rubber is a latex made from rubber, tree, rubber, and grass. It is made of flexible, insulating, impermeable and air. High elastic polymer compound. It is divided into two kinds: natural rubber and synthetic rubber. Natural rubber is made from rubber, tree, rubber, grass and other plants. The synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry or in all fields of life.

Q:What do you pay attention to when using rubber?

Oil: in the process of use, if it has long-term contact with the oil medium, the oil can penetrate into the interior of the rubber to produce swelling, resulting in lower strength and other mechanical properties of the rubber. Oil can cause swelling of rubber, because oil penetrated rubber, resulting in the proliferation of molecules, so that the network structure of vulcanized rubber changes.

Q:Comparison of physical properties of HNBR rubber material with other rubber materials

HNBR has a high temperature resistance of 130~180 degrees, cold resistance of -55 ~ -38 degrees, and good mechanical properties, compared with other polymers, can meet the requirements of the automotive industry. HNBR with ZnO/ methacrylate (MAA) can be used to make V-belt, triangular V-belt, multi base rubber, vibration isolator and so on. It can also prepare sealing ring, sealing element, heat resisting tube and so on. In oil drilling, rubber products are required to withstand high temperature, high pressure, acid, amines, H2S, CO2, CH4 and other tests of steam. The products prepared by HNBR can be acid resistant, oil resistant and solvent resistant. With the ZnO/MAA HNBR reinforcement can be used for the production of drilling mud pump piston and protection box. In addition, the beating method HNBR can be used as a sealing washer washer made of paper oil industry and automobile industry. HNBR heat and radiation resistance properties than silicon rubber, fluorine rubber, poly four vinyl chloride is better, suitable for all kinds of rubber seals for power station, is also used as a hydraulic pipe, hydraulic seals, power station for cable sheath, can also be used for printing and fabric roller, weapons components and aerospace seals, cover, fuel capsule; HNBR latex can be used as a surface coating (painting), textile, paper, leather, metal, ceramic fiber, non-woven adhesive, and foam rubber, latex impregnated products etc.. In addition, with ZnO/MAA, peroxide and high wear furnace HNBR, its comprehensive performance is better than ordinary HNBR.

Q:Does anyone know how to deal with the frosting of rubber and how to prevent it?

The reason: if the formula is in before the precipitation of sulfide precipitation may be white, Zinc Oxide or stearic acid, yellow sulfur may be, after curing products, may be white wax, light green or other color may be. The weather is hot, after curing the product easy to spray cream, can properly reduce the antioxidant.
