There are three main waste tire disposal methods: tire retreading, reclaimed rubber, and reclaimed rubber powder. Among them, tire rubber powder processed from used tires is constantly refined along with the production process, and the status in the rubber product industry is also increasingly important. Rubber products are much more filled. Waste tire rubber powder can not only be used as a filler in rubber products, but also can be used as a large number of main body materials.
1, reduce costs
The tire rubber powder is made of scrap tires that have been crushed and ground under the action of mechanical shear force. The source of raw materials is large and the product price is low. It is used as a powdery rubber material in the production of rubber products, which can reduce rubber raw materials. Dosage, increase the volume of rubber products, reduce the cost of raw materials for rubber products, which is the original purpose of rubber products manufacturers in rubber products mixed with tire rubber powder.
2, improve performance
Tire rubber powder can not only reduce the raw material cost of rubber products, but also improve the performance of rubber products by virtue of its unique molecular structure and performance characteristics: Tire rubber powder has good compatibility with various raw rubber and reclaimed rubber, and can be used in different rubber products. Plays a different role. The use of tire rubber powder in rubber soles can improve the wear resistance of rubber soles; the use of tire rubber powder in tire treads can reduce the dynamic heat generation of tires, improve the abrasion resistance of rubber tires, and prolong the service life; tires are added in rubber floor tiles. The rubber powder can achieve the effects of sound absorption, noise reduction, and shock absorption; the use of tire rubber powder in laying of asphalt roads can improve road surface flexibility, grip, reduce driving noise, reduce cracks, and improve waterproof anti-skid performance.
Tire rubber powder is a kind of powdery rubber material, its particle size, surface morphology, etc. will affect its performance, usually the higher the fineness of tire rubber powder, the better the performance. When the tire rubber powder fineness is high enough, the use of tire rubber powder in the rubber product will hardly affect the tensile strength, elongation at break and abrasion resistance of the rubber product itself, and even increase the wear resistance of the rubber product. , fatigue resistance and tear strength, some rubber products due to the performance required to be mixed with tire rubber powder. At the same time, the higher the fineness of the tire rubber powder, the lesser the effect on the surface smoothness of the rubber product, or the improvement of the lightness of the rubber product.
Different types of rubber products in the tire rubber powder blending amounts are very different, low-grade rubber products can be used in large quantities, and even completely use the tire rubber powder as the main rubber material: For example, rubber tires tire rubber powder blending amount can be To achieve more than 100 copies, tire tread rubber can be mixed with about 10 parts of tire rubber powder, low-grade plastic sheet can be completely used tire rubber powder production. With the continuous improvement of tire rubber powder properties, tire rubber powder will have more and more friendly impact on the performance of rubber products.
