GB7984 Acid Resistant Rubber Conveyor Belts Multi Layer

GB7984 Acid Resistant Rubber Conveyor Belts Multi Layer

1. Product structure
This product uses multi-layer rubberized cotton canvas as the skeleton, and is made of rubber material with good surface covering performance after vulcanization.

Conveyor belt series products include ordinary cotton canvas conveyor belt, nylon (NN) conveyor belt (divided into NN-100 type, NN-150 type, NN-200 type, NN-250 type, NN-300 type, NN-350 type, NN-400 type), polyester (EP) belt (divided into EP-100 type, EP-150 type, EP-200 type, EP-250 type, EP-300 type, EP-350 type, EP-400 type) , Large inclination (wave-shaped ribs) conveyor belt, skirt partition conveyor belt, endless conveyor belt, pattern conveyor belt {Because of the different materials to be transported and the size of the inclination of the conveyor, the shape and height of the pattern are also different. Commonly used pattern conveyor belt varieties such as: herringbone pattern conveyor belt (herringbone conveyor belt includes convex and concave herringbone conveyor belt), eight-shaped pattern conveyor belt, herringbone pattern conveyor belt, U-shaped pattern conveyor belt, cylindrical Pattern conveyor belt, pit pattern conveyor belt, etc., grass pattern conveyor belt, or designed according to user requirements}, water stop belt, PVC or PVG whole core flame retardant belt, etc.; and can provide various special performance conveyor belts (general Flame-retardant conveyor belts, heat-resistant conveyor belts, burn-resistant conveyor belts, high wear-resistant conveyor belts, acid-resistant conveyor belts, alkali-resistant conveyor belts, cold-resistant conveyor belts, oil-resistant conveyor belts, high-temperature resistant conveyor belts, high-strength conveyor belts and food Conveyor belt, Teflon conveyor belt, stainless steel conveyor belt, chain conveyor belt, conveyor belt).

2. Specifications and models
1) According to the customer, it can be cut at will according to the width;
2) According to the different use environments, it is divided into ordinary conveyor belts and includes (ordinary type, heat-resistant type, flame-retardant type, burn-resistant type, acid-base resistant type, oil-resistant type), heat-resistant conveyor belt, cold-resistant conveyor belt, and Acid-base conveyor belt, oil-resistant conveyor belt, food conveyor belt and other models. Among them, the minimum thickness of cover rubber on ordinary conveyor belts and food conveyor belts is 3.0mm, and the minimum thickness of lower cover rubber is 1.5mm; the minimum thickness of cover rubber on heat-resistant conveyor belts, cold-resistant conveyor belts, acid and alkali resistant conveyor belts, and oil-resistant conveyor belts is 4.5 mm, the lower cover rubber should be at least 2.0mm. According to the specific conditions of the use environment, the thickness of the upper and lower cover rubber can be increased by 1.5mm;
3) According to the tensile strength of the conveyor belt cloth layer, it is divided into ordinary conveyor belts, green rubber conveyor belts and powerful conveyor belts. Powerful canvas conveyor belts are divided into nylon conveyor belts (NN conveyor belts) and polyester conveyor belts (EP conveyor belts).

Supplementary note: The strong layer of the strong conveyor belt is polyester canvas (EP), which is divided into EP100, EP150, EP200, EP250, EP300, EP350, EP400, etc.; it can also be nylon canvas (NN) , Can be divided into NN100, NN150, NN200, NN250, NN300, NN350, NN400, NN450, NN500, etc.

3. Product introduction
