Q:What is the relationship between synthetic rubber and crude oil?
Synthetic rubber also has disadvantages, the drawing effect of main disadvantage lies in its relatively poor, tearing strength and mechanical properties are relatively poor, but because of synthetic rubber materials than natural rubber has the advantages of low cost, but also a lot of Companies in the production of low-end products preferred.
Q:What is the specific gravity of natural rubber?
Natural rubber is composed of rubber, hydrocarbon, water, resin, protein, sugar and inorganic salts, and its specific gravity is 0.90~0.93. The natural rubber without impurities is transparent and yellowish, with good viscosity and dielectric properties, and its tensile properties are generally higher than those of synthetic rubber. Soluble in benzene, solvent naphtha, carbon disulfide, carbon tetrachloride, chloroform, turpentine, etc., but not soluble in ethanol and acetone. With halogen, oxygen, ozone, peroxide, sulfur and so on. Widely used in the manufacture of rubber products, such as tires, rubber shoes, hose, tape, wire and cable insulation materials.
Q:Several aspects of rubber aging performance and how to identify them
Heat: increasing temperature can cause thermal cracking or thermal crosslinking of rubber. But the basic function of heat is activation. Increase oxygen diffusion rate and activate oxidation reaction, so as to accelerate the speed of rubber oxidation reaction, which is a common aging phenomenon - thermal oxidative aging
Q:How can I make rubber products brighter?
Special release agent for rubber products, release agent.Mold release agent is an interface coating used on two surfaces that are easy to adhere to each other. It can make the surface of the material easy to break off, smooth and clean. Mold release agent is used in various molding processes, such as glass fiber reinforced plastics, metal die casting, polyurethane foam and elastomer, injection molding thermoplastic, vacuum foaming sheet and extrusion section. In molding, sometimes other plastics, such as plasticizers, leak to the interface, and then a surface remover is needed to remove it.
Q:How is rubber made? What kind of equipment do you need? How much is it?
Machining process:This process involves basic processes such as plasticization, mixing, calendering or extrusion, forming and vulcanizing. Each process has different requirements for the product and cooperates with a number of auxiliary operations. In order to make all the necessary coordination agent in rubber, rubber Plasticating must first go through improving the plastic; then by mixing carbon black and all kinds of rubber and rubber additives are evenly mixed into rubber; rubber shaped blank after extruding; and then the textile materials and rolled hanging glue or glue (or metal material) together formed into semi-finished products; finally after vulcanization will have final semi-finished products made of high elastic plastic. The products with higher precision requirements, such as oil seals, O rings and seals, also need trimming and deburring, and manual trimming, mechanical trimming and cold trimming can be used.
Q:Can rubber products be injection molded and plastic injection functions?
Rubber is an elastic polymer. Rubber can be obtained from the plant sap, can also be man-made, both have many applications and products, such as tires, washers, etc., has become an important economic crop. The cultivation of rubber is mainly concentrated in Southeast Asia, such as Thailand, Malaysia and Indonesia.
Q:Advantages and disadvantages of rubber products
Styrene butadiene rubber SBR(Styrene Butadiene Copolymer) and butadiene styrene copolymers, compared with natural rubber of uniform quality, less foreign body, has better wear resistance and aging resistance, but the mechanical strength is weak, can be combined with natural rubber mixing. Non - oily material advantages: low cost, good water resistance, hardness below 70 with good elasticity, high hardness with poor shortcomings: compression, does not recommend the use of ozone, acid, oil, oil and fat ester and most hydrocarbons. Widely used in tire industry, shoes, cloth and conveyor belt industry etc..
Q:How do ordinary NBR and EPDM materials differ?
Nitrile rubber (NBR) is composed of butadiene and acrylonitrile was prepared by emulsion polymerization, nitrile rubber by emulsion polymerization at low temperature, excellent oil resistance, high wear resistance, good heat resistance, strong adhesion. Its disadvantages are low temperature resistance, poor ozone resistance, poor insulation properties, and slightly lower elasticity. Nitrile rubber is mainly used in the manufacture of oil resistant rubber products.
Q:Explain why butyl rubber is more resistant to oxidation and aging than other elastomers, such as natural rubber
The macromolecular structure unit of natural rubber is isoprene, and the macromolecular chain is mainly composed of CIS -1, 4 polyisoprene. NR is the mechanical and processability comprehensive properties of all rubbers
Q:Aging of rubber parts for automobiles?
Automobile rubber parts aging factors are: oxygen, ozone, heat, light, mechanical stress, moisture, oil, other chemicals or radiation, etc.. Attention should be paid to water and oil here:The alternate action of high temperature and oxygen 1. long-term water and in the external environment under the accelerated aging of rubber;2., the oil will penetrate the rubber, so that swelling occurs, rubber performance will be reduced. Therefore, trucks should avoid shock absorption of rubber bushings, oil and diesel in various occasions, including maintenance.
