   Seals are widely used in life, basically with the mechanical edge of something will use seals. As large as cars, planes, small lighters, mice and so on. Seals must be used. There are many varieties of seals, according to the raw materials can be divided into: the comparison of common silicone rubber sealing ring, fluorine rubber sealing ring, ethylene propylene rubber, PTFE, neoprene, polyurethane and so on. According to the use can be divided into: acid seal, alkali sealing, high temperature seals, low temperature seals, oil seals and so on. Many machines can not work without seals, for example, oil seals, if there is no oil seal, it may leak, and even cause the machine can not work. The oil leaked the news often seen on television, in fact, that is the seal is not good, perhaps can not seal quality. The seal is an important part of the machine, and plays an important role in the operation of the equipment. In order to avoid foreign material entering, it is necessary to use seals in machinery.
   A different seal can operate in a different environment. For example, high and low temperature environment, acid base solution, oil resistance and so on. In different circumstances, the sealing of the job should be selected from different materials, such as the high temperature resistance of fluorine rubber. Important factors sometimes seal hardness is affected by living in the hair, not all seals are soft, such as PTFE sealing stiff. Mechanical seals should be checked frequently and found abnormal should be replaced in a timely manner, for example, seals, deformation, cracking, etc., the main factor affecting the service life of the seal is the operating environment. Temperature is the main factor affecting the hardness of the seal. In order to increase the elasticity of the seal at low temperature and decrease the permanence of the data compression, the formula for improving the data is to add a certain amount of plasticizer to the rubber. Long term immersion in the medium of operation, plasticizers will gradually be absorbed by the operating medium, forming a seal aging shortened. So always check the seal. Avoid aging; form episodes of disturbances.http://www.taien.cn/
