Flame resistant conveyor belt

With the rapid development of industrial automation, industries such as steel, cement, and chemical often use heat-resistant conveyors to transport materials such as sintered ore, coke, and cement clinker. However, due to the high temperature of these materials, coupled with the high-temperature working environment, general heat-resistant conveyor belts are overwhelmed, and the covering rubber and skeleton materials cannot withstand long-term high temperatures. A series of problems such as surface scalding, combustion, large amount of peeling, foaming, skeleton material burning, scalding, etc. commonly occur, which not only affect the service life of the conveyor belt, but also cause huge economic losses to the enterprise. And the heat-resistant conveyor belt can just solve the above problems.

The heat-resistant conveyor belt is composed of a high-temperature resistant layer (covering adhesive), a transition layer, an organic insulation layer, a strong layer, and a heat-resistant layer in sequence. When the covering adhesive encounters high temperature, it produces a microporous carbonization layer, which has burn resistance and can prevent further heat transfer to the belt body, playing a role in high temperature resistance and can withstand material temperatures of 100-800 ℃.

The core of the burn resistant conveyor belt is a metal spiral mesh integral core, which has the characteristics of burn resistance, high temperature resistance, puncture resistance, tear resistance, flame retardancy, low elongation, high interlayer bonding strength, good grooving, 100% vulcanization joint efficiency (joint strength is the same as the conveyor belt), short and easy joint operation time, and is widely used in the transportation of materials in metallurgy, cement, power, coal, mining, casting, chemical and other fields.

The difference between burn resistant conveyor belts and high-temperature resistant conveyor belts

The high-temperature resistant conveyor belt tests the thermal oxidative aging ability of the cover rubber. The damage of the cover rubber is a slow thermal oxidative aging. This type of conveyor belt can demonstrate its advantages in cement plants. The material does not have an open flame and the temperature is between 200-300 ℃. The conveyor belt is often damaged due to the aging of the cover rubber. By improving the quality of the cover rubber, its service life can be extended.

Burning resistant conveyor belt is a destructive use that is suitable for high-temperature applications such as sintering ore in steel plants, and many places even use open flames. In order to extend the service life of rubber conveyor belts, carbon forming agents are often added to the rubber to rapidly carbonize it at high temperatures and prevent further heat transfer to the belt body.

Product advantages

The main advantages of heat-resistant conveyor belts are high temperature resistance, deformation resistance, flame retardancy, and long service life

High temperature resistance

The heat-resistant conveyor belt can operate normally in a high temperature environment of 800 ℃ and is suitable for conveying open flame materials such as sintered ore. The carbonized layer forms irregular cracks at high temperatures, and self cooling is achieved through belt operation to avoid deformation caused by high temperature shrinkage.

2. Anti deformation ability

Using inorganic skeleton materials, the strength loss is small at high temperatures, which can effectively maintain the stability of the belt and prevent structural deformation caused by high temperatures

3. Flame retardant properties

Equipped with flame retardant function, it can reduce the risk of combustion and is suitable for the transportation of flammable materials such as chemicals and coal

4. High joint strength

Adopting a metal spiral mesh integral core structure, the joint strength is consistent with the body, the vulcanization joint efficiency reaches 100%, and the operation time is short and easy to operate

Product Application
