In Baidu Encyclopedia, the powdered rubber refers to the powdered rubber material obtained after the crushed rubber products are crushed and processed, which is the resource for the recycling of the waste rubber and is deeply loved by the rubber products manufacturers. Reclaimed rubber powder has a long history of development. Since the 1940s, it has been used to add rubber powder to rubber products to improve the performance of rubber products and reduce the cost of raw materials for rubber products.
Initially, the recycled rubber powder is only used in the production of rubber products such as rubber outsole, shock absorption pad and asphalt runway which are less demanding on performance. In this case, the particle size of the rubber powder is larger, between 0.5 and 1.0mm. With the progress of rubber powder production technology and equipment, by 1970, it has been possible to produce fine rubber powder (60-150 mesh) with a fineness of 100-250μm, which can be used in the production of automobile tires to improve the tire's Wear resistance; 70 years, China's renewable rubber production technology has begun to mature, the production and application of rubber powder is also more and more, recycled rubber powder rubber products in the field of status is also getting higher and higher; 80s to In the 1990s, the research, production and application of reclaimed rubber powder in China have entered the commercialization stage and entered the active phase. In 1999, the production of reclaimed rubber powder in China achieved a qualitative leap forward. The Zhuhai SEZ Fine Performance Technology Institute Qingdao Green Rubber Co., Ltd. succeeded in freezing the liquid nitrogen JY-type powder production line for fine powder for our country to provide a complete set of production equipment.
Data show that as of 2001, there are more than 40 domestic renewable rubber powder manufacturers, annual output of about 50,000 tons.
The appearance of reclaimed rubber powder not only solves the pollution problem of some waste rubber products, but also plays a great role in the rubber products. For example, the cracking of the road with rubber powder modified asphalt is small and hard to icing and slipping, the development prospect can be described as bright ; In rubber soles, rubber tiles, cushions and other rubber products to improve the wear resistance of rubber products.
With the continuous development of recycled rubber powder production technology, the demand for powder rubber is no longer just stuck in the tire powder body, the market appears more and more EPDM powder, nitrile rubber powder and other products , Of which color EPDM powder used in the school plastic track, nitrile rubber powder can be used as a modifier of rubber products.
Hebei Hongyun renewable rubber factory in accordance with customer demand for the production of different specifications of EPDM powder, NBR renewable rubber powder, tire powder, asphalt modified powder and other products, product quality and low prices, is the rubber products business Ideal partner.
