There are many different kinds of seal products and different working conditions, such as heat resistant, oil resistant, resistant to chemical corrosion and work (
Static, dynamic, rotate and swing, etc. )
Work, speed, pressure, etc.
So for mechanical seal rubber seals
Function is commonly used in mechanical seal rubber, to have good flexibility and low compression permanent deformation, satisfy the special performance requirements of different products using conditions.
As a dynamic seal, rubber are also required to have certain tensile strength, good abrasion resistance, tear resistance performance.
Type O sealing ring is a kind of appearance is of simple structure, various specifications, quantity needed a seal products.
Type O sealing ring sealing quality of life depends on the size precision and rubber.
General requirements rubber has certain mechanical strength, tear resistance and good heat resistance, oil resistance, resistance to chemical media and under the conditions of use to so low compression permanent deformation, is the main index.
According to the requirement, generally there are heat resistant, oil resistant, most use using acrylonitrile-butadiene rubber adhesive.
Type O sealing ring of heat resistant, oil resistant rubber seals material in the formula of the filling reinforcing system, adopt more active low cracking of carbon black, carbon black spray or half reinforcing carbon black, the characteristics of the carbon black is coarser particles, rubber has good elasticity, low heat, low compression permanent deformation, and a large number of filling, reduce the cost of rubber.
Such as type O sealing ring used under the condition of dynamic seal, need to increase the tensile properties, can be more active and part of high wear-resistant carbon black.
