Acid and alkali resistant rubber sheet belongs to a sealed product
Acid and alkali resistant rubber sheet is our company's main product. In terms of production and research and development, we have adopted domestic advanced technology, which has the advantages of corrosion resistance, aging resistance and long service life. In order to let everyone have a further understanding of acid and alkali resistant rubber sheet, I will introduce the working principle of this product and its advantages, and hope to help you, so let's take a look together!
One of the main uses of acid and alkali resistant rubber sheet is as a movable seal. Due to the high rotation speed of the rotating shaft, the sealed products have to bear a large frictional torque, especially in the case of poor lubrication, the heat generation in the sealed area is large, which will cause the rubber to stick or improve the adhesion with metal. Destruction of seals, which in turn leads to seal failure. One of the more effective ways to reduce the temperature in the friction zone is to add a lubricating filler to the rubber to reduce the friction coefficient of the rubber. Such as disulfide and graphite are added to the rubber sheet production formula. In addition, using polytetrafluoroethylene (PTFE), polytetrafluoroethylene has excellent resistance to media and atmospheric aging, has a wide range of use, has good self-lubricating properties, and has a small friction factor. Greatly reduce the surface friction factor of rubber products, improve wear resistance and resistance to media. However, the surface energy of polytetrafluoroethylene is low and it is difficult to compound it with other chemicals. The currently studied polytetrafluoroethylene coating methods are as follows: irradiation grafting method, plasma activation method, chemical corrosion method, static electricity Spray method, media method.
