At present, the vulcanized rubber powders on the market are mostly processed by mechanical or freezing and crushing methods. It is an important form of recycling of waste rubber products. It can be used as a filler or a main material in the rubber and non-rubber industries. Can reduce costs and alleviate the shortage of resources. In the actual production and processing, the quality of vulcanized rubber powder directly affects the quality of products and engineering, so how should the rubber powder purchaser judge the quality of vulcanized rubber powder?
1. What are the common vulcanized rubber powder
Common vulcanized rubber powders are tire rubber powder, nitrile rubber powder, ethylene propylene rubber powder, butyl rubber powder, special rubber powder for highway modified asphalt, etc., where tire rubber powder is usually made of radial tires or bias tires that have lost their use value. Processed; nitrile rubber products, ethylene propylene rubber products and butyl rubber products that have lost use value will be processed into nitrile rubber powder, ethylene propylene rubber powder and butyl rubber powder by mechanical force or freezing method 2LLYY0414, highway modification Asphalt rubber powder is generally processed from all-steel radial tires or other tires that have lost their usefulness.
Vulcanized rubber powder buyers first need to determine the type of vulcanized rubber powder according to the occasion of use of the vulcanized rubber powder.
2. Judge the vulcanized rubber powder products by appearance
When purchasing vulcanized rubber powder, the quality of vulcanized rubber powder can be preliminarily judged by visual observation and hand touch. Under normal circumstances, high-quality vulcanized rubber powder has a uniform texture and contains no impurities such as wood chips, metals, gravel, glass and other non-rubber components that are visible to the naked eye.
3. Index for measuring the quality of vulcanized rubber powder
In the actual application process, the purchase of vulcanized rubber powder can reduce the heating of the rubber powder, ash, acetone extract, rubber hydrocarbon content, carbon black content, iron content, fiber content, tensile strength, elongation at break, etc. The indicators determine the quality of vulcanized rubber powder. Different types of vulcanized rubber powder have different judgment bases. The buyer can request the manufacturer to provide relevant test reports, which can be compared with national standards. It should be noted that the tensile strength and elongation at break of vulcanized rubber powder are only applicable to the quality inspection of tire vulcanized rubber powder of 60 mesh or more.
Vulcanized rubber powder is widely used in the rubber industry and non-rubber industry. The reasonable use of vulcanized rubber powder can further improve the quality of rubber products or non-rubber products while reducing costs. For example, the use of vulcanized rubber powder in tire tires can improve the mileage of tires and Road adaptability, etc., later editors will continue to share with you the application skills and precautions of vulcanized rubber powder in different industries.
