Xinhua Xu seal each performance of each material

Xinhua Xu seals butadiene rubber, isoprene rubber and neoprene preferably 150-160 ?, the maximum does not exceed 170 ? styrene-butadiene rubber, nitrile rubber can be used more than 150 ?, but the maximum does not exceed 190 ?; butyl rubber, EPDM rubber is generally used in 160-180 ?, the maximum does not exceed 200 ?; silicone rubber, fluorine rubber is generally used in Sec sulfur, some optional temperature 170-180 ?, Sec sulfide is selected 200- 230 ?, according to the technical requirements can be selected within the range of 4-24h.

According to Xinhua Xu seals used different materials, nature produces different classification.

1. Xu Xinhua seals high temperature seals

2. Xinhua Xu high pressure seal ring

3. Xu Xinhua corrosion-resistant seal ring

4. Xu Xinhua seal wear ring

Xinhua Xu seal oil, acid, wear, chemical corrosion and other environment continues to play outstanding sealing, damping effect. Thus, Xinhua Xu seal hydraulic and pneumatic transmission system, the most widely used a seal.

Xinhua Xu seals for a variety of sealing methods: static seals, dynamic seals, suitable for all kinds of useful information, and groove dimensions are standardized and interchangeable.

Xinhua Xu seals for a variety of strange sealing medium: oil, water, gas, chemical, or other media mixed media. After selection of a suitable rubber materials and appropriate formulations depict complete the oil, water, air, gas and various chemical mediators useful sealing effect.

Xinhua Xu seal if installed properly, and the use of appropriate conditions, the general is not simple reciprocating reciprocation condition at the onset of roll, or distort, due to a touch area, Xinhua Xu seal with the groove is greater than the conflict on the sliding surface touch the area, and the hydraulic resistance of the O-ring itself would have been able to hinder distorted. Conflict forces also tend to adhere to distribute Xinhua Xu seal in its groove stops moving, because the conflict is greater than static slide conflict, and the roughness of the surface of the trench is not as ordinary sliding surface roughness.

Xinhua Xu seal airtight, sealed system for medium, gaskets in the recommended temperature and pressure of a certain time leak does not occur.

Xinhua Xu compressible seals, gaskets and flange contact surface after connecting bolt should be in good agreement, in order to ensure the seal.

Xinhua Xu creep resistance seals, gaskets under the influence of pressure and temperature load, and creep resistance should be good, or else return to cause the bolt torque loss, resulting in surface stress gasket reduced so hard gas system Give way.

Xinhua Xu chemically resistant seals, gaskets should be chosen from corrosion chemical medium, and not contaminate the media.

Xinhua Xu seal resilience, even under the condition of stability of the system, since the two flanges are connected and influence of temperature and pressure will certainly exist elasticity small displacement, the gasket should be able to compensate for this displacement, to ensure system tightness.
