Cleaning machine is the production, sales, maintenance of high pressure cleaning machine for the whole company, the development of the company technical force is constantly in recent years, technology innovation and production, products are sold throughout the country, by the customer the consistent high praise, today let everyone know about the formula design of sealing ring plunger pump of high-pressure cleaner O.
Rubber, butadiene rubber and styrene butadiene rubber in the molecular chains of conjugated double bonds exist, can absorb and uniform distribution of energy outside, the molecular chain is not easy to damage, at the same time as the conjugated effect and shielding effect, the neighbouring groups it becomes stable, the wear resistance of rubber can improve. In addition, the natural rubber has the advantages of high strength, good technological properties of mixing operation, the choice of adhesive and NR/SBR/BR three.
Reinforcing system selection of wear resistance and reinforcing properties excellent high abrasion / super abrasion furnace black and, dispersed and guarantee the uniformity of carbon black with oil plasticizer, tackifier used solid Malone / pine tar and.
Vulcanization system using semi efficient curing system, to ensure that the rubber material with good comprehensive properties. With antioxidant RD/AM and use, to improve the heat resistance and fatigue properties of rubber compound.
Finally, the O shape sealing ring can be identified as NR/SBR/BR 30/30/40 formula: 7, zinc oxide, stearic acid 2.5, antioxidant 3, black 90, filler 29, oil / solid Malone / pine tar sulfur accelerant 3/5/5, 1.6, 1.7. A total of 247.8. For more information please visit the high pressure cleaning machine cleaning machine: www.qingxijiw.com.
