Rubber gaskets are small rubber parts that play a sealing role in various industries. Depending on the application, different types of rubber can be produced. For example, oil gaskets are usually made of nitrile rubber with waste nitrile rubber as raw material, Both rubber pads can be guaranteed long-term in the oil environment to maintain the same physical properties, but also significantly reduce the cost of raw materials. Xiao Bian to share with you a nitrile rubber reclaimed rubber production of low-cost gaskets formula.
Butyronitrile reclaimed rubber, 20kg; light calcium, 10kg; oil, 1kg; zinc oxide, 0.64kg; stearic acid, 0.32kg; S, 0.36kg; accelerator M, 0.05kg; , 0.02 kg; carbon black N550, 0.5 kg; total: 32.97 kg.
The reclaimed rubber as the main raw material of the formula, and filled with a large number of light calcium, can greatly reduce production costs. In order to ensure the good performance of nitrile rubber gasket performance, the choice of production of nitrile rubber gasket reclaimed rubber, the cost of allowable conditions, should pay attention to the following questions:
1, nitrile rubber reclaimed the higher the fineness the better, especially in the production of ultra-thin oil-resistant gasket, the nitrile rubber reclaimed fineness requirements higher, the higher the reclaimed rubber fineness, the smoother surface of the rubber gasket ;
2, the use of nitrile rubber reclaimed rubber production, raw materials and accessories stored in the process should pay attention to moisture, especially nitrile rubber and light calcium regeneration, the use of moisture-absorbing materials and accessories will produce gaskets gaskets;
3, the best choice of environmentally friendly butyronitrile reclaimed rubber, especially used in the food industry oil rubber gasket.
