soft film calender machine supply is a common industrial material, widely used in vibrating screens, conveyors, seals and other fields. soft film calender machine supply What skills do you have when purchasing?

When purchasing soft film calender machine supply, we must look at these six elements: surface, paint, material, structure, bonding degree and density hardness.

1. Surface of soft film calender machine supply

soft film calender machine supply During production, there may be some impurities or untreated surfaces. These impurities or the surface is not smooth will make the soft film calender machine supply easy to damage, easy to pollute, and affect the service life. Therefore, when purchasing soft film calender machine supply, we must pay attention to the surface treatment.

Second, the paint quality of soft film calender machine supply

The floor is placed in the light to see whether the surface has bubbles, pitted spots, orange peel phenomenon, and then see whether the paint is rich, full, and smooth.

Third, soft film calender machine supply material

soft film calender machine supply common materials are natural rubber, butyl rubber, nitrile rubber and so on. Among them, natural rubber has better toughness and elasticity, while butyl rubber and nitrile rubber have better wear resistance and oil resistance. According to the specific use environment and requirements, choose the appropriate material of soft film calender machine supply.

Fourth, the structure of soft film calender machine supply

Check whether the structure of the soft film calender machine supply is symmetrical and balanced from the two ends of the soft film calender machine supply, whether it meets the principle of symmetrical balance, if it meets the structure, it is stable.

Fifth, the glue degree of soft film calender machine supply

See whether the floor layer of soft film calender machine supply is closely glued between layers with two hands, whether there will be stratification.

Six, soft film calender machine supply density hardness

The important parameters of soft film calender machine supply are density and hardness. In general, the denser the soft film calender machine supply, the better the strength and durability. The higher the hardness index of soft film calender machine supply, the greater the density is generally, and the toughness and elasticity are better. In the purchase process, it is also necessary to choose the appropriate density and hardness of soft film calender machine supply according to the specific use scenario and requirements.
