Burn-resistant conveyor belt NN200 Special Conveyor Belts
When the cover rubber encounters high temperature, a microporous carbonized layer is produced, which is resistant to burning and can prevent further heat transfer into the belt body, reducing the internal strength of the tape. The carbonized layer generates irregular small cracks during the operation of the belt body, which is cooled by the belt body.
Inorganic materials with a diameter structure are used as the skeleton material of the burn-resistant conveyor belt. The use of this skeleton material solves the difficulty of high-temperature carbonization of cotton canvas and high-temperature shrinkage and deformation of nylon and polyester canvas used in the past, and has low strength loss at high temperatures. The characteristic of not shrinking and deforming.
The unique adhesive formula design ensures that the adhesive strength between the rubber and the frame material is much higher than that of ordinary heat-resistant belts, and the interlayer adhesive strength at high temperature is ≥3N/mm.
Withstand material temperature 200-600℃, instantaneous 800℃.
The latest type of burn-resistant conveyor belt: metal mesh core conveyor belt
The belt core is a metal spiral mesh integral belt core, which is resistant to burning, high temperature, flame retardant, puncture resistance, tear resistance, low elongation, high interlayer adhesion strength, good groove formation, and 100% vulcanized joint efficiency. The joint operation time is short and easy to implement. Among them, the use temperature of the metal mesh core high temperature resistant conveyor belt is 150 ℃-200 ℃; the use temperature of the metal mesh core burn resistant conveyor belt is 200 ℃-800 ℃; the metal mesh core conveyor belt has good performance at different temperatures. performance.
