Tire rubber powder has a wide range of influence in the production of rubber products. The rational use of tire rubber powder can not only reduce the cost of raw materials, but also improve the processing performance of the polymer and improve the physical properties of the product. In the actual processing and production process, the process performance and application characteristics of tire rubber powder from different raw material sources are different. Rubber product manufacturers can choose the appropriate tire rubber powder according to actual needs, taking into account quality and cost.
1. Source of tire rubber powder
Tire rubber powder mainly includes waste tire rubber powder with natural rubber as the main component, waste tire rubber powder mainly composed of synthetic rubber, waste tire retreaded tire rubber powder and tire rubber powder under Akron abrasion. Different rubber powders are used in rubber The application effects in products are different, and there is a gap in usage and dosage. At present, the tire rubber powders on the market are mainly products directly processed from waste tires; usually, the raw rubber used in automobile truck tires is mainly natural rubber, and the rubber raw materials for car tires are mainly synthetic rubber.
2. The effect of tire rubber powder in rubber products
Compared with the rubber without tire rubber powder, the rubber with tire rubber powder has improved flex crack resistance, and the tensile strength and tearing strength are slightly reduced (negligible). The physical properties of the rubber Basically no impact on performance.
In actual production, waste tire rubber powder with natural rubber as the main component and synthetic rubber as the main component have similar effects in rubber products; use retreaded tires to polish the mechanical strength of tire rubber powder 2LLYY1111 Tire rubber powder is lower than other sources; the rubber powder polished by the Akron abrasion test has the best effect in the rubber compound, and the mechanical performance of the rubber product is better.
3. Tips for choosing tire rubber powder for rubber products
Tire rubber powder is widely used in various rubber products, and the amount of tire rubber powder in different types of rubber products is different. For example, the amount of tire rubber powder in the tread rubber of automobile tires is generally between 5-15 parts, and the amount of rubber powder in ordinary rubber shock absorption materials can be increased to one or two hundred parts, which can be determined according to actual needs. Generally speaking, the tire rubber powder polished by the Akron abrasion test has better performance and can be used to produce high-quality rubber products; however, due to limited output, tire rubber powder directly processed from waste tires is usually selected.
Tire rubber powder is used as the main material or as filler in the production of different types of rubber products. The reasonable use of tire rubber powder in rubber products can achieve a win-win situation of quality and cost; later editor will continue to share waste tire rubber powder with you Specific application in rubber products.
