GB/T7984 300mm-3000mm Conveyor Rubber Belt Anti Sticking
Ordinary conveyor belts, also known as ordinary cotton canvas conveyor belts, are suitable for conveying materials under short-distance and medium-load conditions. The pulling force is relatively low and the load-bearing capacity is limited.
1. Ordinary conveyor belts are divided into many specifications and models according to the use environment and requirements.
(1) According to the size of the transportation volume, it is divided into: B300, B400, B500, B600, B650, B800, B1000, B1200, B1400, B1600, B1800, B2000 and other commonly used models (B stands for width, in millimeters).
(2) According to the different use environment, it is divided into: heat-resistant conveyor belt, cold-resistant conveyor belt, acid and alkali resistant 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.

2. Supplementary information
Ordinary conveyor belts of new materials should also adapt to high temperature and low temperature performance: it can operate continuously in the temperature range of -73℃～+260℃; excellent resistance to other chemical substances; good electrical performance: good insulation performance, insulation The layer has high breakdown resistance strength; good layer separation: anti-sticking, low friction coefficient, smooth surface; good dimensional stability: a new type of ordinary conveyor belt, which is stable in size under high temperature and high pressure, and is not easy to deform.
Executive standard: GB/T7984-2001
Covering layer: Tensile strength is not less than 15Mpa, elongation at break is not less than 350%, abrasion is less than or equal to 200mm3, the average value of interlayer adhesion strength of longitudinal samples is not less than 3.2N/mm between cloth layers, and between cover rubber and cloth layers Not less than 2.1 N/mm.
