1. The main raw material for rubber products is raw rubber as the basic material, while raw rubber is grown in tropical, subtropical rubber trees collected by artificially cutting the bark.
2. A variety of complexes, in order to improve certain properties of rubber products and added supporting information. To enhance mechanical strength, limit product variants. Ingredients must be accurately weighed according to the formula during raw material preparation. In order to make the raw rubber and mating agent can be evenly mixed with each other, it is necessary to process the data raw rubber in the 60--70℃ drying room after the glue, broken glue into small pieces, the mating agent has lumps such as paraffin, stearic acid, rosin and so on to crush. If the powdery contains mechanical impurities or coarse grains need to be screened to remove liquid such as pine tar, gumalon need to heat, melt, evaporate moisture, filter impurities.
3. Fiber data are (cotton, hemp, wool and a variety of artificial fibers, synthetic fibers and metal materials, steel wire) as the skeleton data of rubber products. The mating agent should be dried otherwise easy to agglomerate, mixing if can not disperse uniform vulcanization when bubbles will affect product quality.
