??Mat rubber seals advantage?

??Mat rubber seals are widely used in static sealing joint surface of pipes, pressure vessels and a variety of housing.

??Leak mat rubber seals three forms: interface leakage, penetration leakage and destructive leakage. Where previously both as the main form.

??Cause mat rubber seals leak generated interface are: combining surface roughness and deformation; sealing surface is not pressed; coupling bolt clamping surface deformation, elongation; seal plastic deformation; gasket material aging, cracking and deterioration . Interface leakage constant leakage of 80% to 90% of the total.

??Mat rubber seals penetration leakage can occur, in which butyl rubber penetration leakage at least, to do with butyl rubber gasket is available in 1.33 × 10-6Pa under vacuum. Neoprene seals, nitrile rubber seals used in the 1.33 × 10-6Pa vacuum.

??Mat rubber seals in the harsh environment, to ensure a long effective seal, must have the following eight important characteristics:

??Tightness gasket

??Sealing system for media, the gasket leak does not occur within the recommended temperature and pressure of work some time.

??The compressibility of the gasket

??Contact surface gaskets and flanges after connecting bolts should be in good agreement, in order to ensure the seal.

??Gasket creep resistance

??Shims under the influence of pressure and temperature load, and creep resistance should be good, or else return to cause the bolt torque loss, resulting in surface stress gasket reduced so hard gas system leak.

??Gasket chemical resistance

??The choice of the gasket should not be corrosive chemical media, and the media can not be contaminated.

??Pad rubber seal material filling function is complex topography and the gap disadvantageous construction, to act as a seal.
