Description

EPDM disjunctor gasket that sealing performance is good

[ technical field ] A method for producing a semiconductor device

The utility model relates to a technical field of screw gasket, especially technical field of EPDM disjunctor gasket.

[ background of the invention ]

Gaskets are mechanical seals between two objects, typically to prevent pressure, corrosion, and natural thermal expansion and contraction leakage of the tubing between the two objects. Since the machined surface may not be perfect, the irregularities can be filled using shims. The gasket is typically made of a sheet material such as paper, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, fiberglass, or plastic polymer. The conjoined gasket is one of gaskets and is mainly used for sealing bolts, the conjoined gasket is generally formed by compounding a metal gasket and a rubber gasket, the rubber gasket is mainly made of EPDM ethylene propylene diene monomer which is a copolymer of ethylene, propylene and a small amount of non-conjugated diene, and is one of ethylene propylene rubber and EPDM rubber, because a main chain of the conjoined gasket is composed of chemically stable saturated hydrocarbon and only contains unsaturated double bonds in a side chain, the conjoined gasket has excellent aging resistance such as ozone resistance, heat resistance, weather resistance and the like, and can be widely used in the fields of automobile parts, waterproof materials for buildings, wire and cable sheaths, heat-resistant rubber tubes, adhesive tapes, automobile sealing parts and the like. The sealing performance of the existing EPDM gasket is poor, and the EPDM gasket is extruded due to the fact that a screw is screwed to be over-tightened in the using process, so that the EPDM gasket is damaged.
