FAQs
1. What is the safety factor for your PVC solid woven belts?
Our PVC belts are designed with a safety factor of 10, meaning the working tension is one-tenth of the tensile strength.
2. What is the maximum transporting angle for PVC belts?
Standard PVC solid woven belts are typically recommended for transporting angles less than 16 degrees.
3. How do you ensure the belt will not ignite under friction?
We perform drum friction tests ensuring surface temperatures remain below 325C with no sparks or ignition occurring.
4. Can you customize the belt width for specific mine galleries?
Absolutely. As a custom solution provider, we can manufacture widths according to your specific underground conveyor system requirements.
5. What makes the solid woven carcass superior to layered belts?
The integral woven structure eliminates the risk of ply separation (delamination), providing much higher resistance to tearing and impact.
6. Are these belts resistant to chemicals and oils?
The PVC impregnation provides a high level of resistance to various chemicals, moisture, and oils commonly found in mining environments.
7. Do you provide samples for safety certification testing?
Yes, we can provide samples of our PVC flame retardant belts for your local mine safety authority or internal technical evaluations.
