Two methods for the development of mechanical seal materials

　2017-02-15　　

In the development of mechanical seal materials, spraying new thermosetting plastics and spraying non-ferrous Jinpu powder can also be used, which is in line with the ideal mechanical seal material structure criteria. This kind of cladding layer can be used to seal oil and gas drilling casings. The drilling depth must reach thousands of meters or even tens of thousands of meters. The task placed in front of the drilling machinery is to improve the sealing of the connection. The composite polyethylene-zinc sowing surface layer can meet this tightness requirement. From a sealing point of view, a nearly ideal cladding structure can be formed. The tantalum surface layer forming the blended structure can be controlled by the phase state and the particle size of the components. It can be a cladding layer of a multiphase system or a metal organic compound cladding layer.　　269.html,
