It is the primary indicator of the main indicators of the mechanical force, tear properties, and good heat resistance, oil resistance, chemical dielectric, and well-known heat resistance, oil resistance, chemical dielectric.A hydraulic rubber seal showing an O-shaped structure, its structure is simple, and the specifications are different, and it is a need for a large number of sealing products.

The seal size and trench have achieved standardization, cheap, easy to use, easy to use and purchase. Acrylate rubber can be used for the desired temperature (180 ° C) oil-resistant seal. The sealing performance is good, the static seal does not leak. The sealing quality life of the hydraulic O-seal depends on the dimensional accuracy and rubber.

With self-sealing, no periodic adjustment. It can be seen that it is very wide. Requires higher temperature oil-resistant rubber products with fluoro rubber, heat-resistant silicone rubber. When the working pressure is high, the method of increasing the hardness of the O-sealing ring is to increase the amount of carbon black, China Mechanical oil seal Manufacturers but the amount of filling is too high, the mix is ​​difficult, and the sulfide base is damaged, and the rubbing is easy to bu .

Effectively increase the heat resistance and oil resistance of sulfide gum, and reduce the sealing ring structure compression permanent deformation. The advantages of the O-shaped rubber seal: The sealing ring is simple, small size, and the installation site is compact.

In the case of using the same rubber, such as butyl nitrile adhesive, in order to improve heat and oil resistance, reduce compression permanent deformation, peroxide (such as using DCP) vulcanization systems or effective sulfurization systems (low sulfur is high) . 6, strong adaptability, use is very wide. .

So, what is the chemical characteristics and logistics properties of PTFE oil seals?Electrical energy polytetrafluoroethylene oil sealing material is very low in a wide frequency range, and the breakdown voltage, volume resistivity, and arc resistance are high.

Polytetrafluoroethylene does not absorb, zero flame retardant, antioxidant, and ultraviolet rays are extremely stable, so it has good weather resistance.High oil seals for car Manufacturers molecular compounds polymerized by tetrafluoroethylene, have excellent chemical dielectric stability, ozone, weather resistance, flame retardancy, low temperature performance, electrical insulation, good anti-aging endurance and mechanical strength It is used in the metallurgical industry oil seal, both Foshan IdiTlifluoroethylene oil seal (tetrafluorobass).

The polymerization reaction in the polymerizable industry is to stir in a large amount of water, which is used to disperse the reaction heat, and facilitate control temperature.Inorganic hybrid sulfates, there are automotive peroxides to initiating agents, and the system can also be used to initiate the system.

Chemical properties weathering aging: Long-term exposure to the atmosphere, the medium performance remained unchanged by irradiation performance and low permeability; flame retardancy: restricted oxygen index of 90 or less, using temperature -55 ~ + 260 ° C; acid and alkali resistance: it is insoluble in strong acid, strong base and there is a machine solvent; anti-oxidation resistance: corrosion resistant to strong oxidants.

It has always been to people who like to buy imported hydraulic seals is the advanced production process, precision processing technology, isolation of raw materials, resulting in a relatively good performance of the seal performance stability to domestic oil seals.

Foreign hydraulic oil sealing materials relatively reliable in China, the research China Industrial crankshaft oil seal Manufacturers is relatively profound, and various experiments are also relatively perfect;domestic oil seals compared to it, the price is cheaper, the delivery period is short, and when choosing the hydraulic oil seal of the shield, it should be considered according to various factors. 

 The gap is not much different, which can import hydraulic oil seal, which make people more inclined to refer imported hydraulic oil seals? First, the advantages of imported hydraulic oil sealing package are as follows:Imported parts is long, higher price, increase cost, make customer products Attenuation in the market, the market share becomes small. 

There will be many disadvantages if considered from a single aspect.The production process of the domestic machinery oil seal repair package has become more mature,seal manufacturers believe that the construction of the construction machinery can be relieved to reference the domestic oil seal repair kit, today's domestic repair package materials performance is actually with foreign product performance. It is also very strict in product size tolerance;the shield machine oil seal can meet the more harsh conditions
