Q:Are natural latex rubber products?
In the fresh latex without any substance, the rubber hydrocarbon accounts for only 20%-40% of the total amount, and the remainder is a small amount of non rubber components and water.
Q:What are the applications of rubber airbags in the automotive field
China's expanding automotive market offers great opportunities and development opportunities for specialty rubber and further extends its application. At the same time, the performance and environmental protection requirements of automobile rubber products have been improved. Automobile industry drives rubber products market.
Q:Why is rubber forest a green desert?
Long ago, the people have the knowledge of the use of wild rubber. Before Columbo came to the new world, no one outside the Americas knew that there was a species called rubber, and never thought that there would be a magical liquid out of the tree trunk that could change the progress of human civilization one day.
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: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.
Q:How do ordinary NBR and EPDM materials differ?
Three EPDM (EPDM) is a non conjugated diene copolymer of ethylene and propylene and a small amount of an ethylene propylene rubber, represented by EPDM, because of its main chain is composed of saturated hydrocarbon chemical stability, only in the side chain containing unsaturated double bond, so the ozone resistance, heat resistance, weather resistance etc. aging resistance, can be widely used in automobile parts, building waterproof materials, wire and cable sheath, heat-resistant hose, rubber belt, automotive seals etc..
Q:The action of various ingredients in rubber formula
Curing system: vulcanizing agent, accelerator, active agent, anti coke agent,
Q:What is the definition of mixed rubber?
Mixed rubber, also called synthetic rubber, is a synthetic, highly resilient polymer. Also known as synthetic elastomer, is one of the three major synthetic materials, its yield is only lower than synthetic resins (or plastics), synthetic fiber.
Q:What kind of rubber coated aluminum alloy (metal) better
White Silicone, or at cyanide rubber, you have to brush the surface of metal binder, general is muruk we do, rubber products, these things often encounter
Q:What are the differences in the properties of neoprene models?
Good physical and mechanical properties, oil resistance, heat resistance, fire resistance, sunlight resistance, ozone resistance, acid and alkali resistance, chemical reagents. The disadvantage is cold resistance and poor storage stability. With high tensile strength, elongation and reversible crystallinity, good adhesion. Aging resistance, heat resistance. Excellent oil resistance and chemical resistance. Weatherability and ozone resistance are second only to that of ethylene propylene rubber and butyl rubber. The heat resistance and the nitrile rubber, the decomposition temperature of 230~260 DEG C, short-term resistance at 80~100 DEG 120~150 DEG C, can be used for a long time, with a certain flame retardancy. Oil resistance second only to nbr. Good resistance to inorganic acids and alkalis. Cold resistance is slightly worse, electrical insulation is poor. Rubber poor storage stability, will have a "sulfur" phenomenon, Mooney viscosity increased, hard rubber. Foreign brands are: AD 1, 30 (USA), A-90 (Japan), 320 (Germany), and MA40S (France).
