The most important sealing material of mechanical seal:

In recent years, following the rapid development of modern engineering, mechanical seals for various purposes, such as high temperature sealing, low temperature sealing, ultra low temperature sealing, high pressure sealing, high vacuum sealing, high speed sealing, and various flammable and explosive , Poisonous, highly corrosive media, containing suspended particles such as mud and sand, have successively produced sealing problems, and correspondingly put forward higher requirements for sealing. In order to ensure that the seal has a good sealing performance and a long service life, in addition to a reasonable sealing structure and manufacturing process, the more important thing should be a material with good sealing performance. Therefore, for the sealing device, if the structure is the guide and the process is the guarantee, the material is the foundation, that is to say, the sealing material is the key to ensuring the sealing performance and service life. The improvement of sealing level and the development of sealing materials are closely linked. The requirements of modern engineering for sealing are, to a large extent, the requirements for sealing materials.　　255.html,
