Whole core flame retardant conveyor belt
The whole core flame retardant conveyor belt is made of a whole core impregnated with polyvinyl chloride impregnated paste or plasticized. The utility model has the advantages of high strength, large volume, balanced transportation, etc. the utility model has the advantages of good flame retardant, antistatic, impact resistance, abrasion resistance, corrosion resistance, etc.. The utility model is mainly suitable for underground transportation of coal mines, and can also be used for material transportation in metallurgy and chemical industry.
The whole core flame retardant conveyor belt can be divided into PVC type and PVG type. PVC on the covering layer are PVC plastic cover, single-sided adhesive is larger than 0.8mm, PVG on the covering layer are nitrile rubber and PVC with single thickness 1.5mm-4.5mm. PVC conveyor belt transport angle <16o, PVG type conveyor belt transport angle <20o, can be used for coal mine, underground transportation.
The characteristics of the belt: the belt body does not take off, small elongation, impact resistance, tear resistance. According to the knot can be divided into different types of PVC (plastic surface), PVG (based on the PVC attached to the rubber surface) flame retardant core belt, the implementation of MT/914-2002 standards. Type PVC is suitable for material transportation under the condition of 16 degrees below the dry condition.
Type PVG suitable for the conveyance of wet and wet materials with a dip of 20 degrees below
