Knowledge of sealing materials for mechanical seals

　2017-02-07　　

The development of modern science and technology and the integration of the sealing discipline of mechanical seals require engineers and technicians to have a more comprehensive knowledge of sealing materials. The reasonable selection and correct use of various sealing materials will bring significant technical and economic benefits. The knowledge of sealing materials mainly consists of the following parts:

(1) Modern engineering requirements for sealing materials, classification and development trend of sealing materials for mechanical seals;

(2) Selection of sealing materials (friction pair pair materials, mechanical seals, gaskets, fillers, adhesives, O-rings, asbestos rubber sheets);

(3) Classification, performance, specification and brand of ceramic sealing materials;

(4) Classification, performance, specification and brand of graphite sealing materials;

(5) Classification and performance, specifications and brands of rubber sealing materials;

(6) Classification of resin-based polymer sealing materials, classification and performance of engineering coarse materials for sealing, specifications and brands of resin-based molecular sealing materials, classification and performance of sealants, specifications and brands of sealants;

(7) Other non-Jincheng sealing materials (leather, felt, cardboard, asbestos);

(8) Classification and performance, specifications and brands of ferrous and non-ferrous metal sealing materials;

(9) New sealing materials (flexible graphite, composite materials).　　253.html,
