In January last year, our company shipped a 35-meter flame-retardant conveyor belt with a bandwidth of 1000mm to a coal mine in Papua New Guinea for the transmission and transportation of mining materials.

  Flame-retardant conveyor belts, also known as whole-core flame-retardant conveyor belts, are made of an integral belt core that is impregnated with polyvinyl chloride impregnated paste and then plasticized or vulcanized. It has the characteristics of high strength, large transportation capacity, and balanced transportation. At the same time, this product It has good flame retardant, antistatic, impact resistance, wear resistance, corrosion resistance and other properties.

 Flame-retardant conveyor belt could prevent the accumulations of static electricity, mainly through the following ways.

1. Choosing the appropriate flame-retardant material: Flame-retardant conveyor belt usually use fabric or rubber materials, these material themselves have good conductive properties against the static electricity and can prevent the generation of static electric and accumulation in some degrees.

2. Adding a conductive layer: we can add the conductive layer on the surface of the flame retardant conveyor belt such as conductive tape or conductive rubber layer. These conductive could introduce the static electricity to the ground, thereby reducing the risk of static electricity accumulation.

3. Reasonable grounding design: for transportation systems are required to prevent the static electricity of accumulation, so reasonable ground design is very important. The metal parts and the conductive layer should be connected with the ground to conduct the static electricity into the ground.

4. Reducing the static electricity that generated by friction: The important reason to generate friction is friction, hence reduce the ways of friction could prevent the accumulation of static electricity. Which can adjust the tension of the conveyor belt, choose the appropriate conveyor speed, the correct conveyor belt and the right contact way of conveyor belts to reduce the friction.

5. Control the temperature of humidity: Static electricity will be generated easily under a high temperature and a low humidity environment. So control the temperature and humidity of the environment is the key to preventing the static electricity accumulation. Maintaining the appropriate the temperature and humidity is good for reducing the rate of generation speed of static electricity. Except all these methods have been mentioned, we can adopt other measurements such as.

6. The using of eliminating device of static electricity: static electricity elimination is a device that could quickly eliminate static electricity. It can be placed around the conveyor belt through neutralizing and eliminate static electricity by releasing the gas irons into the air. This device can reduce the generation risk of static electricity.

7. Adding the dissipation and grounding devices: add dissipation and grounding devices at the connection between the conveyor belt and the mechanical equipment to directly introduce static electricity into the ground.

8. Regular maintenance and inspection: Regularly maintain and inspect the flame retardant conveyor belt to ensure it can operate normally and to promptly detect and solve potential static electricity accumulation problems.
