Rubber products are products made of rubber as raw material, and after simple or complex processing, they are circulated in large quantities in the market. Rubber products are used in all walks of life, in different substances and rubber mingling and cooperation, rubber products greatly improve our quality of life. The following small make-up will give you an introduction to the testing of rubber products is what kind, what are the projects, and is the classification of rubber products is what kind of situation.
Rubber product testing
One, the concept of rubber performance testing
Generally do the rubber performance test, in accordance with ISO, ASTM, DIN, GB, HB and other standards, to rubber, vulcanized rubber, rubber products and rubber auxiliary compatibility with the physical and chemical properties of the agent, mechanical properties and other tests.
Two, rubber performance index items:
Physical and mechanical properties: density, hardness, surface resistivity, dielectric properties,? Tensile properties,? Impact performance,? Tearing properties,? Compression properties,? Adhesive strength Abrasion resistance,? Low-temperature performance, low-temperature performance, low-temperature performance, low-temperature performance, low-temperature performance Resilience
Aging performance: heat aging, ozone aging, ultraviolet aging, salt spray aging, xenon aging, carbon arc lamp aging, halogen lamp aging
Liquid resistance: lubricating oil, gasoline, oil, acid, alkali, organic solvents, water resistance
Combustion performance: vertical combustion, alcohol blowtorch combustion, propane combustion in the alley, smoke density, combustion rate, effective combustion heat value, total smoke release
Applicability performance: hydraulic resistance, impulse test Calorific value, total smoke release
Applicable performance: hydraulic pressure resistance, pulse test, electrical conductivity, watertight, airtight
Related applications:
Tires, fenders, shoe soles, water stops, seals, conveyor belts, rubber hoses, cables and wires, automotive interiors, construction materials, fast consumer rubber rolls, rubber sheets, medical and health care rubber products, rubber decompression products, rubber shock absorbing products, etc.
Three common rubber testing projects:
1, rubber evaluation: volatile matter, ash, tensile strength, fixed extension strength
2, production parameters: Menni viscosity, thermal stability, shear stability, vulcanization curves, Menni burning time
What are the rubber products
General Rubber
Rubber refers to partially or completely replace the use of natural rubber, such as styrene-butadiene rubber, butadiene rubber, isoprene rubber, etc., mainly used in the manufacture of tires and general industrial rubber products. General-purpose rubber is in high demand and is the main variety of synthetic rubber.
Styrene Butadiene Rubber
Styrene Butadiene Rubber is made from butadiene and styrene **** polymerization, is the largest production of general-purpose synthetic rubber, emulsion polymerization of styrene butadiene rubber? , solubilized styrene butadiene rubber (SBR)? and thermoplastic rubber (SBS).
Sunbutadiene rubber
Butadiene by solution polymerization of the system, sunbutadiene rubber has a particularly excellent cold resistance, abrasion resistance and elasticity, but also has good aging resistance. The vast majority of cis-butadiene rubber is used in the production of tires, and a small portion is used in the manufacture of cold-resistant products, cushioning materials, as well as adhesive tape, rubber shoes and so on. The drawback of cis rubber is that the tear resistance is poor, and the resistance to wet slippery performance is not good.
Isoprene rubber
Isoprene rubber is short for polyisoprene rubber, produced by solution polymerization. Isoprene rubber, like natural rubber, has good elasticity and abrasion resistance, excellent heat resistance and good chemical stability. Isoprene rubber raw rubber (before processing) strength significantly lower than natural rubber, but the quality of uniformity, processing performance is better than natural rubber. Isoprene rubber can replace natural rubber to manufacture heavy-duty tires and off-road tires can also be used to produce a variety of rubber products.
Ethylene propylene rubber
Ethylene propylene rubber is synthesized with ethylene and propylene as the main raw materials, aging resistance, electrical insulation properties and ozone resistance is outstanding. Ethylene propylene rubber can be a large number of oil-filled and filled with carbon black, products with lower prices, ethylene propylene rubber chemical stability, abrasion resistance, elasticity, oil resistance and styrene butadiene rubber close. Ethylene propylene rubber has a wide range of uses, can be used as tire sidewalls, rubber strips and inner tubes as well as automotive parts, can also be used as wires, cable skins and high-voltage, ultra-high-voltage insulating materials. It can also be used to make light-colored products such as rubber shoes and sanitary products.
Chloroprene rubber
It is chloroprene as the main raw material, through homopolymerization or a small amount of other monomers **** polymerization. Such as high tensile strength, heat resistance, light resistance, excellent aging resistance, oil resistance are better than natural rubber, styrene-butadiene rubber, male rubber. With strong flame resistance and excellent resistance to delayed combustion, its chemical stability is high, good water resistance. The disadvantages of chloroprene rubber are electrical insulation properties, poor cold resistance, raw rubber in storage is not stable. Chloroprene rubber has a wide range of uses, such as used to make transportation belts and transmission belts, ? Wire, cable wrapping materials, the manufacture of oil-resistant hoses, gaskets and chemical-resistant equipment lining.
What are the rubber products, rubber products, how is the test, these little in the above have been in the above to give you a detailed introduction. The use of rubber products is inseparable from the modern chemical and chemical industry, these modern science and technology development, making rubber products become more and more varieties, but also makes our daily life become more colorful, there is more convenient. If you are interested in rubber products, you can understand the rubber products.
