Short fiber has high elongation, tear resistance, puncture resistance, low heat generation, small compression deformation, and easy processing. It can be used as a reinforcing material to improve the physical properties of rubber products. When using recycled rubber to reduce the production cost of rubber products, rubber product manufacturers can use short fibers to reinforce the recycled rubber and reduce the cost of raw materials. So which recycled rubber products can use short fibers? What is the specific role of short fibers in different recycled rubber products?
1. The role of short fibers in rubber tubes
Short fibers play different roles in different types of rubber hoses. In general, medium and low pressure hoses such as irrigation hoses can use the short-term orientation of short fibers to improve the pressure resistance of the hose and the radial orientation to improve the stiffness of recycled rubber compounds. The use of short fibers in the high-pressure braided hose can also effectively prevent the metal wire from cutting through the rubber material, and ultimately achieve the purpose of improving the service life of the high-pressure braided hose.
2. The role of short fibers in rubber bands
Among various types of rubber belt products, short fibers are more widely used in V-belts. When using high-strength latex recycled rubber or tread recycled rubber to produce rubber V-belts, the use of a suitable amount of short fibers in the compression layer can significantly improve the lateral stiffness and longitudinal flexibility of the V-belts. Not easy to slip, increase friction to a certain extent, and reduce noise generated during operation. The filling amount of the short fiber 2LLYY0403 in the rubber belt is generally controlled at about 5-20 parts.
3. The role of short fibers in rubber tires
Recycled rubber is generally not used alone in rubber tires, and is often used in combination with natural rubber or styrene-butadiene rubber. Recycled rubber and raw rubber are used together to produce rubber tires. A small amount of short fibers can improve the tire's abrasion resistance, puncture resistance and tear resistance. Generally, 2-3 parts of short fibers are added to tire tread rubber. The physical and mechanical properties of the surface glue have been significantly improved. In actual production, a suitable amount of short fibers can also be added to the rubber tire crown, triangle strip, bead and other parts.
4. The role of short fibers in seals
The sealing effect of the cloth seal is remarkable. When using recycled rubber to produce high-pressure-resistant cloth-sealed seals, short fibers can be used instead of cloth-jacketed to achieve the purpose of improving the production process and reducing costs.
5. The role of short fibers in other products
When using recycled rubber to produce rubber products such as waterproof sheets, rubber shock absorbers, rubber product manufacturers can also use an appropriate amount of short fibers to improve the overall performance of the product. The test shows that the puncture resistance and cut resistance of the waterproof material containing short fibers will be significantly improved; adding a small amount of short fibers to the rubber shock absorber can take advantage of the characteristics of short fiber energy absorption to further improve the comprehensive performance of recycled rubber products and reduce More raw material costs.
Short fibers are widely used in recycled rubber products. Short fibers have been used in many rubber tubes, tapes, tires and seals to achieve the dual purpose of improving quality and reducing costs.
