Q: When rubber products are hardened, what methods soften?
Either hardening or vulcanization. Vulcanized rubber becomes elastic rubber. This is an irreversible process. The elastomer can be changed into a plastic regenerated rubber by the desulfurization process.
Q: What about the Poisson's ratio and modulus of elasticity of three yuan ethylene propylene rubber (EPDM)?
The Poisson's ratio and modulus of elasticity of three yuan ethylene propylene rubber (EPDM) are approximately:Rubber elastic modulus 0.0078GPa, Poisson's ratio 0.47.
Q: High strength rubber repairing agent
Rubber repairing agent is a new kind of cold vulcanizing belt repairing material. It is usually made of two components. After mixing and mixing, it forms a gum paste, which can be painted at any angle. It is easy to be shaped and is very convenient to use.
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 to remove the peculiar smell of rubber products?
The general method is to add some flavor spices used to degrade or reduce all kinds of rubber produced in the processing or use process in acids, alkoxy compound such as smell, method is effective, but not fundamentally solve the problem.
Q: How to identify the tire rubber is raw or cooked
All use glue tire manufacturing, rubber is the parent material of rubber products, rarely used directly.
Q: Natural rubber, general rubber, synthetic rubber. Are these all rubber products?
Not rubber products, rubber classification, rubber is divided into natural and synthetic rubber, synthetic rubber and general rubber and special rubber! The so-called rubber products refers to the use of rubber as raw materials to produce products, such as tires, belts, conveyor belts and so on.
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: What kind of rubber is suitable for waterproof aprons?
One to do waterproof rubber ring, choose ethylene propylene rubber! The main sealing ring of fire ditch pipe is mainly made of ethylene propylene rubber!! Physical and chemical properties have corresponding national standards!
Q: How is the temperature range of rubber determined?
Rubber is based on rubber molecular structure and molecular weight as well as microscopic view to determine temperature range!
