High-strength reclaimed rubber generally refers to tire reclaimed rubber with tensile strength between 10-18 MPa. As the demand for high-strength reclaimed rubber continues to increase, high-strength reclaimed rubber on the market continues to increase. However, the quality of high-strength reclaimed rubber products has been uneven due to the limitations of manufacturers' production processes and production equipment. How to choose genuine high-quality, high-strength reclaimed rubber is a concern for rubber product companies, and how to ensure high-strength reclaimed rubber products Quality is something that reclaimed rubber factories should do well.

1, choose strictly

(1) High-strength reclaimed rubber must be strict when selecting used tire raw material types, such as the use of small tires, heavy-load tires, bias tires, radial tires (steel wires), and used tires such as engineering tires, tractor tires, etc. Less than the demand for high strength reclaimed rubber needs.

(2) The high-strength reclaimed rubber should be selected from waste tire rubber powders with higher rubber ratios, taking in account the ratio of synthetic rubber and natural rubber, and the rubber components contained in the crown, shoulders, and sidewalls of the tire structure. The rubber content of different types of used tires is not the same as the rubber type. For example, the content of steel radial tires is generally about 45%, including 100% butylbenzene and butadiene rubber, and 70% or more of the rubber content is 55%. Left and right; biased tires in the natural rubber content of about 70%, synthetic rubber content of 30%; radial steel radial 100% natural rubber, but also 100% synthetic rubber.

(3) High-strength reclaimed rubber featured 1200 used tire rubber powder as the main raw material, which can fundamentally guarantee the “high strength” of high-strength reclaimed rubber.

2, high-strength reclaimed rubber to have a complete purification process: waste materials in the workshop to clean, regenerative sulfur to establish standards, activator to establish detection; waste tires crushed, the need to establish fiber and magnetic separation device to ensure purification; Strong reclaimed rubber desulfurization If there is waste gas, waste water, need to set up the absorption treatment device, guarantee the environmental protection to reach the standard; In the rubber mixing process, there must be filtration and purification to ensure that the high-strength recycled rubber product has no impurities.

3. A strict production management system shall be established in the production of high-strength reclaimed rubber to ensure advanced equipment, strict inspection, and full supervision. For example, high-strength tire reclaimed rubber raw material sizing section fineness and fiber content, can only be used after magnetic separation qualified; check the accuracy of desulfurization measurement, heating and heat preservation standardization; plasticity of semi-finished plastic products up to standard, refining the thickness of the film meet the standard, finished cold Can be packaged.

4. It is understood that at present, more than 80% of reclaimed rubber enterprises in China do not have full-scale testing, and 40% do not have testing. The situation is quite serious.

5. Innovation is the driving force for the survival and development of each company. No matter if it is a high-strength reclaimed rubber production process or production equipment, it must keep pace with the times; talents are the root of business survival, and every reclaimed rubber factory must have professional technology. Personnel can provide technical guidance during the production process of recycled rubber products and supervise the whole process; professional technicians can guide the important role of innovation. Both are indispensable.
