What kind of rubber is suitable for waterproof aprons?
Rubber is a kind of macromolecule elastomer that can deform greatly under external force and can quickly recover its original shape when the external force is lifted.Rubber is divided into: natural rubber, synthetic rubberAmong them, synthetic rubber is divided into: general rubber, special rubber.General rubber:Styrene butadiene rubber, butadiene rubber, butyl rubber, EPDM rubber, chloroprene rubberSpecial rubber:Nitrile rubber, chloroprene rubber, chloroprene rubber, fluorine rubber, epichlorohydrin rubber, silicone rubber, polyurethane rubber, polysulfide rubber, acrylic rubber
Typical properties of rubber material are low glass transition temperature and high elasticity. The main properties of common rubber materials are shown in the schedule after the teaching materials.
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!
The vulcanized rubber is a linear or branched structure, because of its low strength, little elasticity, hardening of the cold, softening of the heat, dissolution of the solvent, etc., which makes the products useless. Therefore, the rubber products must be vulcanized, deformed, meshed or of a shape structure to be of practical value.Proper vulcanization of the rubber can maintain the high elasticity of the rubber and the strength of the rubber. At the same time, in order to increase product hardness, strength, wear resistance and tear resistance, while adding inert filler in the process (such as Zinc Oxide, clay, chalk and barite etc.) and reinforcing filler (such as carbon black).
