Polyurethane ground rollers for coal minesIntroduction:

　　Polyurethane ground rollers used in coal mines rely on supporting and protecting steel wire ropes to lift and lower on slopes. They have the characteristics of being sturdy, wear-resistant, with a long service life, moderate weight, and easy installation. They are safe and reliable for long-term use and are currently the mainstream product of ground rollers.

Polyurethane ground rollers for coal minesFeatures:

　　1. Hardness range. It still has the elongation and resilience of rubber under high hardness. The hardness range of 300 * 150 polyurethane roller elastomer is Shore A10-D80.

　　2. High intensity. Under rubber hardness, their tensile strength, tear strength, and load-bearing capacity are much higher than those of general rubber. At high hardness, its impact strength and bending strength are much higher than those of plastic.

　　3. The wear resistance of polyurethane floor rollers is very outstanding, generally within the range of 0.01-0.10 (cm3)/1.61km, which is about 3-5 times that of rubber.

　　4. Oil resistant. Polyurethane elastomer is a highly polar polymer compound with low affinity for non-polar mineral oil, and is almost not corroded in fuel oil and mechanical oil.

　　5. Good oxygen and ozone resistance.

　　6. Excellent vibration absorption performance, capable of providing vibration reduction and buffering effects. In the mold manufacturing industry, replacing rubber and springs.

　　7. Has good low-temperature performance.

　　8. Radiation resistance performance. The polyurethane roller used in coal mines has excellent resistance to high-energy radiation and still has satisfactory performance under a radiation dose of 10-10 Gy.

　　9. Has good machinability (can be machined, milled, ground, or drilled).
