NN or EP core Conveyor Belt 3 plies, 4 plies with rubber cover

According to their characteristics, conveyor belts can be divided as below:

1. Heat-resistant conveyor belt: it is made of multi-layer rubber cotton canvas (polyester cotton cloth) or polyester canvas covered with high-temperature or heat-resistant rubber, which is bonded together by high-temperature vulcanization. It is suitable for convey hot coke and cement below 175 °C. , Slag and hot castings;

2. The flame-retardant conveyor belt, also known as the whole core flame-retardant conveyor belt, is made of the entire belt core after being plasticized or vulcanized by impregnation with a polyvinyl chloride impregnating paste. At the same time, the product has good flame retardant, antistatic, impact resistance, wear resistance, corrosion resistance and other properties;

3, Cold resistant conveyor belt, choosed by cotton canvas, nylon canvas or polyester canvas as the core, cover rubber using natural rubber and butadiene rubber, a combination of high elasticity, impact resistance, cold resistance, etc. It is normally used in the environment.

4, Acid and alkali resistant conveyor belt, a kind of working environment suitable for bulk material with acid and alkali, such as phosphate fertilizer manufacturing, seawater sun salt, covering rubber using rubber and plastic blending and filled with inert materials excellent in acid and alkali resistance.

a, The longitudinal tensile strength of the belt is not lower than the following nominal values: 160, 200, 250, 315, 400, 500, 600, 630, 800 N / mm

b. The longitudinal break elongation of the full thickness of the belt shall not be less than 10%. The longitudinal reference force elongation of the full thickness of the belt shall not be greater than 4%.

c, Straightness: not more than 25mm

d. Adhesive strength between layers:
