Rubber gasket is also a kind of accessories used in railway track,and its basic application field is gasket,its raw material is made of polymer through vulvulation,and then add some filler and pigment and other additives made of rubber,has excellent compressibility and resilience performance.
Rubber gasket only needs a very low preload can play an effective sealing role in low temperature and low pressure mining,easy to disassemble and assemble and uneven sealing surface can also achieve good sealing effect,because rubber oh has the expansibility and permeability resistance,the formation of a very effective seal for resisting gas and fluid through.Commonly used rubber gasket materials are natural rubber,butadiene rubber,ethylene propylene rubber,chlorine rubber,silicone rubber,nitrogen rubber and so on.
Natural rubber vulcanized after natural rubber elasticity,mechanical strength,bending resistance,tear resistance,impact resistance to alkali and dilute acid has good corrosion resistance,non-polar solvent resistance,oil resistance is poor in oxygen and ozone under the action of easy aging.
