The processing of waste tires in tire reclaimed rubber is the most important treatment method for waste tires, and the raw materials of the tire reclaimed rubber are widely available and the product price is low, which can be used to significantly reduce the cost of raw materials in the production of various rubber products. However, the concept of cost reduction for some rubber product companies that have just come in contact with reclaimed rubber is rather vague: How much cost can be reduced by using tire reclaimed rubber? How can we reduce more raw material costs?
Reclaimed rubber production equipment and production processes continue to advance, so the types of tire reclaimed rubber produced are also more and more, different types of tire reclaimed rubber performance is different, the use is not the same. Some low-priced ordinary tire reclaimed rubber fineness of about 30-40 mesh, can produce some low-grade molded rubber products, physical and mechanical properties are not high but the production cost is particularly low, such as ordinary rubber gasket; superfine tire reclaimed rubber fineness Around 80 mesh, it can not only produce molded rubber products, but also can produce extruded rubber products to ensure smooth and bright products; environment-friendly tire reclaimed rubber can produce pollution-free, non-radioactive, non-permeable export rubber products, and develop products abroad. Market; high-strength tire reclaimed rubber tires are generally used as a raw material for the top, effective rubber hydrocarbon content, good elasticity, excellent wear resistance, can replace some of the natural rubber production such as bridge bearings, railway rail mats and other high-strength black high wear-resistant rubber products.
Therefore, the first step in using tire reclaimed rubber to reduce the cost of raw materials is to select the appropriate index of tire reclaimed rubber, we do not need to use high-index tire reclaimed rubber to produce low-grade rubber products (such as the use of ultra-fine tire reclaimed rubber to produce low-grade molded rubber sheet), This will only increase the cost of raw materials, and this is not necessary at all; but we can not use low-priced tire reclaimed rubber to produce high-grade rubber products. The quality of rubber products is unqualified and the market is lost. Therefore, there is no use in saving raw material costs.
The proportion of different types of rubber products theoretically used in tire reclaimed rubber is not certain. Usually, the proportion of tire reclaimed rubber used in the production of conveyor belt products is about 5%, and that of triangular belt rubber products is 20%. The amount of tire reclaimed rubber is 40%, and the proportion of rubber reclaimed rubber hoses can be increased to about 50%. Some low-grade molded rubber products can fully use tire reclaimed rubber. Different types of rubber products need different kinds of tire reclaimed rubber products. The rubber products and reclaimed rubber have different indexes, the price is different, and the proportion of tire reclaimed rubber is different. Therefore, how much raw material cost can be reduced for tire reclaimed rubber can not be generalized. We can only reduce raw material costs as much as possible while meeting the demand for rubber products. This requires proper tire reclaimed rubber products and reasonable rubber product formulation.
The proportion of rubber products used in tire reclaimed rubber to reduce costs is directly related to the tire reclaimed rubber index, the amount of reclaimed rubber blended, and the performance requirements of reclaimed rubber products. Rubber product companies must be cautious when selecting tire reclaimed rubber for production. , Eco-friendly products choose green tire reclaimed rubber, extruded products choose ultra-fine tire reclaimed rubber, high-strength rubber products choose tire top reclaimed rubber, high-strength reclaimed rubber, etc.; only choose the rubber product index closest to the reclaimed rubber products Can reduce more raw material costs.
