In the early 1990s, the disposal of used tires (waste rubber) was mainly buried and stacked. I believe everyone knows that used tires will not degrade naturally even if they are buried for 100 years. If all the used tires in the world adopt the method of burying used tires, the environmental pollution caused by the polymer materials and chemical compounding agents will be difficult to return. According to statistics, China's tire production in 2014 exceeded 562 million, while the amount of waste tires generated was about 10 million tons, and it increased at a rate of 5% to 6% per year. A large amount of waste tires can not only be degraded automatically, occupying land resources, but also risking fires and breeding mosquitoes. How to properly dispose of these solid wastes has become a major problem facing all countries in the world.
In fact, waste tires are not nothing, but instead they are treasures: 22 to 24% of synthetic fibers such as nylon can be processed into plastic products: 16 to 18% of steel wire is the raw material for high-quality spring steel: up to 58-60% rubber The mixture can be made into recycled rubber and vulcanized rubber powder. It is widely used not only in the rubber industry, but also in the building materials industry, the plastics industry, the coatings industry, and roads and sports fields. Let's take a look at several ways to use used tires at home and abroad:
1, thermal energy utilization
Many power plants, paper mills, and steel mills in the United States, Europe, and Japan use used tires as fuel.
2, recycling
(1) Production of recycled rubber.
(2) Making rubber powder. Compared with the production of reclaimed rubber, the processing process is simple, there is no problem of waste water and exhaust gas pollution, and the performance is superior. It can be widely used in various rubber products, sports fields, decorative materials and plastic modification, etc. It is environmental protection and resource recycling. A promising recycling approach.
