Seal USES a very wide range in the life. Basically, the seals and mechanical contact are used together. Big to motor cars and aeroplanes, small to light the mouse, and so on. You must use a seal. Many different kinds of seal, according to the raw materials can be divided into: contrast ordinary silicon rubber sealing ring, fluorine rubber seal, ethylene propylene rubber, ptfe, chloroprene rubber, polyurethane, etc. According to the user's use can be divided into: acid sealing strip, alkali resistance, sealing strip, heat sealing, cold sealing strip, oil seal, etc. Many machines can't use seal, oil seal, for example. If there is no seal, may be the spill and resulting in failure of the machine. The news of the oil spill often see on television. In fact, that is, the seals do not good, the quality of the seal may not. Seal is an important part of the machine, and plays an important role in the operation of the equipment. In order to prevent foreign bodies to enter, it is necessary to use the machine in the seals.
Seal of the different USES can work in different environments. The high and low temperature environment, for example, acid and alkali solution, oil resistance, etc. Unlike sealing material used in the environment, to choose different raw materials, such as high temperature properties of fluorine rubber. Sometimes the seal hardness is also the important factors that affect live-birth application. Not all seals are very soft. PTFE seals, for example, are very hard. Should always check the mechanical seal, and shall timely change anomalies. For example, seal deformation, fracture, etc. The main factors that affect the service life of the seals is operating environment. The temperature is the main factors influencing the sealing hardness. In order to increase the seals in the low temperature flexibility and reduce the persistence of data compression, improve data formula need to add a certain amount of plasticizer in rubber. When long time into the medium, plasticizer will gradually absorbed by the working medium, aging and shorten the seal. So the seal should be regularly check. To avoid the happening of aging.
