The rubber powder processed from waste rubber products can be recycled into the rubber industry and non-rubber fields, which can not only reduce costs, but also solve the problem of part of the waste rubber occupying land and polluting the environment. In actual production, waste rubber powder is relatively more used in tire processing, industrial conveyor belts, rubber floor mats, rubber soles, and road paving. Enterprises choose appropriate application methods to reduce costs while ensuring quality.
1. Tire industry
Tire rubber powder is commonly used in tire production. Experiments show that by adding 5-10 parts of tire rubber powder to the car tread rubber, the flexural resistance, abrasion resistance and bonding strength of the tread are improved, and the mileage of the finished tire is increased; in the sidewall rubber of radial tires 2YLYY526 Incorporating an appropriate amount of tire rubber powder can further improve the flexural resistance of the rubber, without affecting the processing performance of the rubber and the mechanical strength of the vulcanized rubber; the amount of tire rubber powder in the tire can be appropriately increased.
In tire production, the higher the fineness of the rubber powder, the better the application effect, and the surface-modified activated tire rubber powder has the better application effect. Reasonable use of tire rubber powder can not only reduce the cost of rubber tire raw materials, but also improve the rubber processing technology and the comprehensive indicators of the finished product, and ultimately achieve the purpose of improving production efficiency and extending service life.
2. Industrial conveyor belt
At present, industrial conveyor belts have higher requirements for product performance and life; mixing an appropriate amount of tire rubber powder into the rubber conveyor belt can reduce the cost of raw materials. For example, adding about 30-50 parts of rubber powder to the cover rubber of industrial conveyor belts made of natural rubber/styrene-butadiene rubber/butadiene rubber can significantly reduce the cost of raw materials, improve product vulcanization efficiency, and better process performance. The cost is greatly reduced. Activated rubber powder has a better mixing effect in industrial conveyor belts, and the dosage can be increased appropriately.
Products such as EPDM rubber powder and nitrile rubber powder can also be used in corresponding types of rubber conveyor belts to reduce the cost of raw materials. In actual production, selecting a small roller pitch to refine the rubber powder on the open mill can further destroy the original cross-linked structure in the rubber powder, increase the surface area of the rubber powder particles, improve the combination of vulcanized rubber powder and rubber, improve the blending effect, and improve Comprehensive performance of conveyor belt.
Rubber powder can be used not only in automobile tires, industrial conveyor belts and other fields, but also in the fields of rubber floor mat production, rubber sole preparation and road paving. Reasonable use of rubber powder during use can also achieve the purpose of improving the process and reducing costs.
