Calcium carbonate is an inorganic compound, commonly known as graystone, limestone, stone powder, marble, etc., raw materials, low processing costs,
Non-toxic, high whiteness, can be used in natural rubber, butyl rubber, nitrile rubber to improve the performance of tires, hoses, tapes and rubber seals, auto parts and other rubber products. Reclaimed rubber as the exception of natural rubber, synthetic rubber outside the third largest category of rubber, production and processing are also inseparable from the calcium carbonate.
Recycled plastic production and processing of calcium carbonate used in the process are mostly light calcium carbonate, also known as precipitated calcium carbonate, white powder or colorless crystal, non-toxic, odorless, non-irritating, and all including renewable rubber Rubber has good compatibility, there are reinforcing, filling, color, improve processing technology and the performance of products, the most important role is to fill, reduce the cost of recycled rubber products.
1, low price of calcium carbonate, reclaimed rubber products formula to add calcium carbonate, can increase the volume of recycled rubber products, plastic raw materials to save the cost of reclaimed rubber (usually higher price of reclaimed rubber calcium carbonate filled large);
2, reclaimed rubber products formula, calcium carbonate can replace white carbon black, titanium dioxide and other expensive white filler, thereby reducing production costs;
3, Recycled rubber material by adding the right amount of calcium carbonate can improve product performance, rubber products to obtain higher tensile strength, abrasion resistance, tear strength;
4, the hardness of reclaimed rubber products can also be adjusted by adjusting the amount of calcium carbonate filling;
5, reclaimed rubber added calcium carbonate can significantly improve the rubber reinforcing properties, adjust the viscosity and improve the rubber operability.
The use of recycled rubber production of rubber products, reduce production costs, improve processing technology, improve product performance, calcium carbonate is essential. Different types of reclaimed rubber and its products, the added amount of calcium carbonate is different, must be based on the actual situation.
