The recycling and utilization of waste tire rubber is an important field of environmental protection and resource recycling. The following is a detailed explanation of the methods for recycling and reusing waste tire rubber:
1、 Tire refurbishment
Tire retreading is a direct and effective method for recycling and reusing waste tire rubber. Through a series of treatments such as cleaning, testing, repairing, and vulcanization of tires, waste tires can be restored to their original performance and their service life can be extended. The service life of refurbished tires can usually reach 60% to 90% of that of new tires, while the price is only 25% to 50% of that of new tires. This method not only saves raw materials, but also reduces the production cost of tires, while reducing the pollution of waste tires to the environment.
2、 Production of recycled rubber
Crush the waste tire rubber and convert it into recycled rubber through mechanical or chemical methods. Recycled rubber has good elasticity and adhesion, and can be used to produce various rubber products such as tires, hoses, tapes, etc. This method can not only reduce the production cost of rubber, but also improve the performance of the rubber material. However, it should be noted that there are certain technical difficulties and environmental pollution issues in the production process of recycled rubber, so effective measures need to be taken for prevention and control.
3、 Preparation of rubber powder
Waste tire rubber can also be prepared into rubber powder through methods such as room temperature crushing and room temperature chemical methods. Rubber powder has a wide range of applications, such as sports plastic sports fields, amusement parks, rubber floor tiles, waterproofing membranes, waterproof coatings, and modified asphalt for highways. Adding waste tire rubber powder to asphalt can improve its flexibility and durability, thereby extending the service life of the road surface. In addition, rubber powder can also be used as a filler or toughening material for the production of various rubber and plastic products.
4、 Cracking and recycling
Cracking is a relatively thorough method for processing waste tire rubber. Through cracking treatment, waste tire rubber can be converted into valuable resources such as fuel oil and carbon black. This method can not only reduce the pollution of waste tires to the environment, but also achieve the recycling of resources. The fuel oil generated during the cracking process can be used for power generation or as a chemical raw material; Carbon black can be used in the production of rubber products, inks, coatings, etc.
5、 Prototype direct utilization
In addition to the above methods, waste tire rubber can also be directly utilized as a prototype. For example, using waste tires to make furniture, art, fenders for ports and docks, etc. These utilization methods not only have creativity and practicality, but also can reduce the pollution of waste tires to the environment.
In summary, there are various methods and approaches for the recycling and utilization of waste tire rubber. In practical applications, the most suitable recycling method should be selected based on factors such as the material and quantity of waste tire rubber, as well as the purpose and conditions of recycling. At the same time, we should strengthen technological research and innovation, improve the efficiency and quality of waste tire rubber recycling, and make greater contributions to environmental protection and resource recycling.
