China is a large tire production country. At present, China's tire production has reached more than 133.56 million, ranking third in the world. China can produce more than 50,000 waste tires every year. With the increase of car ownership, the production of waste tires will also increase significantly. How to recycle in a reasonable, environmentally friendly, and healthy manner to prevent pollution to the environment is not only a worldwide problem but also a new issue facing the recycling of resources in China. Waste tires are called "black pollution". How to recycle and use these waste tires well, turn waste into treasure, and turn harm into profit, this is a very serious problem we face. With the development of industry, the proportion of China ’s rubber dependence on imports has greatly increased, and this situation cannot be resolved reasonably at present; the state advocates environmental protection industry, recycling industry, green industry, encourages and supports the reuse of waste rubber, and According to investigations, the current recycling rate of waste rubber in China is less than 3%; in order to meet the needs of China ’s industrial development and reduce import stress, the processing of waste rubber into rubber powder and rubber particles is environmental protection for the reuse of waste rubber Recycle green sunrise industry. And the use of tire shredders can eliminate this awkward situation!
Tire shredders have various shapes because each manufacturer has its own unique design, but according to actual production needs and specific shredding requirements, the internal knife rollers of tire shredders are basically divided into four types, Respectively: single-axis knife roller, double-axis knife roller, four-axis knife roller, coarse crushing knife roller. Therefore, we can divide tire shredders into four categories: single-shaft tire shredders, dual-axis tire shredders, four-axis tire shredders, and rough tire shredders.
Due to the shortage of retread able tires and the lack of relevant standards, the domestic waste tire processing industry is in a sluggish situation. At present, most of the waste tire recycling industry is individual farmers, lack of recycling knowledge and tools, low efficiency, high cost, and coverage radius Small, resulting in a recycling rate of less than 50% in China. How to change the status quo of the domestic waste tire industry?
1. Collection of waste tire disposal fees
The collection of waste tire disposal fees in the tire production or sales process can imitate the practice of the extended producer responsibility system adopted by western developed countries.
2. Implement a strict system for the use of waste tires
Implement a strict licensing system for the transportation, storage, treatment, and reuse of waste tires, and introduce policies to encourage standardized and powerful tire recycling enterprises to enter the field of waste tire recycling, and provide certain subsidies to increase the regular enterprises to engage in recycling through economic leverage Industry enthusiasm.
3. Li tire retreading enterprises
The introduction of policies encourages tire retreading companies to provide tire management and services to car owners, extend tire life, reduce the production of waste tires, and ensure that the quality of retreaded carcass is controllable from the source.
4. Strengthen the crackdown on illegal small factories
We will resolutely ban small indigenous oil refineries and raise the cost of environmental violations.
With the rapid development of the automotive industry, the number of used tires is increasing because of their intractability, degradation, and environmental pollution. These characteristics were once called black pollution.
Faced with such a large resource, why do many people dare not to recycle used tires? Many people began to "the idea of scrapping used tires."
Because of the characteristics of tire rubber such as wear resistance, aging resistance, waterproofing, shock absorption, etc., the treatment of waste tires is mainly concentrated on the rubber particles and rubber powder. These rubber powders and rubber particles are widely used in modified asphalt to make waterproof Materials, rubber floor tiles or rubber runways, etc.
In addition, the separated rim thick steel wire and the thin steel wire inside the tire can also be used for reprocessing and use.
On the other hand, if the recycling of used tires can be achieved, it is also in line with China's current sustainable development ideas, that is, it can obtain economic benefits from it, realize waste reuse, save resources, and reduce harm to the environment.
