1. According to the size of the transportation volume, it is divided into: B200 B300 B400 B500 B600 B650 B800 B1000 B1200 B1400 B1600B1800 B2000 and other common models (B stands for width
Degree, in millimeters).
2. According to the different environments, it is divided into ordinary conveyor belts (common type, heat-resistant type, flame-retardant type, anti-burning type, acid-base type, oil-resistant type), heat-resistant conveyor belt, cold-resistant conveyor belt, acid-proof
Alkali conveyor belt, oil-resistant conveyor belt, food conveyor belt and other models. The minimum thickness of the cover tape on the ordinary conveyor belt and the food conveyor belt is 3.0mm, and the lower cover rubber is at least 1.5mm;
The minimum thickness of the cover tape, the cold-resistant conveyor belt, the acid-resistant conveyor belt and the oil-resistant conveyor belt is 4.5mm, and the lower cover rubber is 2.0mm. The specific conditions of the use environment can be pressed.
1.5mm to increase the thickness of the upper and lower cover rubber.
3. According to the tensile strength of the conveyor belt, it is divided into ordinary conveyor belt and strong conveyor belt. The powerful canvas conveyor belt is divided into nylon conveyor belt (NN conveyor belt) and polyester conveyor belt (EP conveyor belt).
Supplementary note: The strong layer of strong conveyor belt is polyester canvas (EP), which is divided into EP100 type, EP150 type, EP200 type, EP250, EP300 type, EP350 type, EP400 type, etc. It can also be nylon canvas (NN). Can be divided into NN100, NN150, NN200, NN250, NN300, NN350, NN400, NN450, NN500, etc.
(1), ordinary conveyor belt (including high-strength nylon conveyor belt) products implement GB7984-2001 standard.
Ordinary conveyor belt:
Cover layer: Tensile strength is not less than 15Mpa, elongation at break is not less than 350%, wear loss is ≤200mm3, interlayer adhesion strength is between not less than 3.2N/mm between longitudinal layers of the longitudinal sample, between the cover rubber and the cloth layer Not less than 2.1 N/mm
Full thickness longitudinal elongation at break is not less than 10%, full thickness longitudinal reference force elongation is not more than 1.5%
Nylon (NN), polyester (EP) conveyor belt:
Cover layer: tensile strength is not less than 15Mpa, elongation at break is not less than 350%, wear loss is ≤200mm3
Interlayer adhesion strength The average value of the longitudinal sample is not less than 4.5N/mm between the layers, and the gap between the cover rubber and the cloth layer is not less than 3.2 N/mm.
