6层帆布、上胶厚度4.5mm下胶厚度1.5mm共定做100米。表示如下 NN200-B800×6 4.5+1.5 100米
Depending on the working environment, the working face thickness of heat-resistant, cold-resistant, oil-resistant and acid-alkali-resistant conveyor belts should not be less than 4.5mm, and the thickness of upper and lower cover glue should be multiple of 1.5. The order of conveyor belt indicates width (mm), number of layers, top cover thickness (mm) +bottom cover thickness (mm), length, strong conveyor belt indicating canvas type; heat, cold, oil and acid and alkali resistant conveyor belt should be noted in text. Ring conveyor belt and pattern conveyor belt should be explained in detail. For example, the NN200 conveyor belt has 800 bandwidth, 6 layers of canvas, 4.5mm glue thickness and 1.5mm glue thickness. It is customized to 100 meters. Represents the following NN200-B800*64.5+1.5 100m
