Introduction
PVG Core Flame Resistant Conveyor Belt is composed of multi-layer cotton canvas or polyester canvas and high-temperature resistant rubber, which is mostly used in mines, power plants, construction, and other fields, and has a good performance in conveying slag, cement, and high-temperature castings. At the same time, because of its long service life, good heat resistance, and low belt weight, it is favored by many users. This product is made of nylon filament and cotton fiber, which constitute the whole core of the conveyor belt. It is made of rubber compression molding on the basis of a normal PVC conveyor belt. Because of the addition of rubber, this structure greatly improves the grooving performance of the conveyor belt, and makes it significantly improved in terms of skid resistance, cold resistance, wear resistance, etc.
Features
1. The production process of PVG Core Flame Resistant Conveyor Belt: PVC slurry, core impregnation, rubber compound plasticization, cover plate, curing, finished product.
2. This product has good flame retardant and antistatic properties, and fully meets the requirements of MT914-2008.
3. Because it is vulcanized by adding a rubber surface to the whole plastic belt body, it can be used for conveying materials at an angle below 20 ° and can be used at the same angle in a humid environment.
4. The PVG Core Flame Resistant Conveyor Belt adopts high-quality polyester filament with high strength and low elongation in the warp direction and high strength and medium modulus nylon filament in the weft direction, so it has the advantages of high strength, low elongation, and light weight.
