First look at the rubber surface of the china TC70 CONVEYOR BELT. The glue surface of a good china TC70 CONVEYOR BELT should be flat, no bubbles, no grooves and no dry marks.

Finger pressure: Use your fingernail to pinch the rubber surface. High glue china TC70 CONVEYOR BELT will not pinch or break. The pinch marks will recover immediately. The lower the colloid content, the slower or no recovery.

Odor: The conveyor belt with high glue content has no peculiar smell and slight odor, and the conveyor belt with high recovery rubber has an extremely unpleasant odor.

Look at the belt core: the high-quality china TC70 CONVEYOR BELT core layer is the same layer, the glue thickness is uniform; the lower conveyor belt will have different thickness.

china TC70 CONVEYOR BELT is a kind of conveyor belt product with high frequency, so it is necessary to strengthen the management and control of the conveyor belt processing process to ensure the qualified rate of the product.

The belt should look smooth and be dense on the inside. First, look at the appearance of the conveyor belt, the appearance is smooth and flat, no grooves, no bubbles, no drying. The second is sniffing. If the nose does not choke and the smell is small, the glue content is high. On the contrary, the glue content is low; secondly, pinch the rubber surface with your fingernails for 3-5 seconds, the conveyor belt with high glue content will not be clamped or clamped. If it breaks, those with low gum content will recover slowly or not. This is also an easy way to determine the amount of rubber on the belt; it is finally identified by the core of the belt. If the thickness of the belt core is uniform and the number of layers is the same, it is a high-quality conveyor belt, otherwise it is an inferior conveyor belt.
