Classification of sealing materials for mechanical seals

As the working conditions of mechanical seals are becoming more and more complex, it is obvious that it is difficult to meet the increasingly demanding requirements of mechanical seal systems by using a single mechanical seal material. With the advancement of sealing technology, there are more and more types of sealing materials. Because of this, at present, there is no unified classification method for sealing materials. The most common is to divide the sealing materials into two categories: solid sealing materials and liquid sealing materials. Solid sealing materials include non-metal sealing materials and metal sealing materials.

Non-metallic sealing materials mainly include: ①ceramic sealing materials; ②graphite sealing materials; ③rubber sealing materials; ④resin-type off-molecule sealing materials; ⑤polymer-based composite materials; ⑥inorganic non-metallic pen composite materials; ⑦others Non-metallic sealing materials (leather, asbestos, paper, felt, etc.).

Metal sealing materials mainly include: ferrous metal sealing materials (cast iron, cast steel, carbon steel and alloy steel) and non-ferrous metal sealing materials (copper and copper alloys, aluminum and aluminum alloys, other non-ferrous metals and alloys).

Liquid sealing materials mainly include adhesives and magnetic fluid sealing materials developed in modern times. Adhesives are often divided into resin-based adhesives, rubber-based adhesives and inorganic adhesives. Magnetic fluid sealing materials are divided into oil-based magnetic fluid sealing materials, water-based magnetic fluid sealing materials, diester-based magnetic fluid sealing materials, and fluorocarbon-based magnetic fluid sealing materials.　　264.html,
