How to distinguish the quality of heat-resistant conveyor belt, the application of heat-resistant conveyor belt is mainly reflected in metallurgy, construction and other industries, conveying sintering coal mine, coke, cement clinker and other high-temperature materials, structural materials use domestic high-temperature canvas, special formula design is a good solution to the problem of poor adhesion, poor adhesion between layers. It has the characteristics of light weight, long service life and high temperature resistance.

How to distinguish heat resistant conveyor belt?

1. The choice of suitable heat-resistant conveyor belt not only depends on its thermal strain, but also depends on the strain capacity of chemical machinery; The temperature of the material conveyed by the conveyor belt and the surface temperature of the conveyor belt should change according to the properties, composition, surface structure shape and particle size of the material. For example, when the temperature of a large area of material is 150 degrees (coke or sinter ore) and the contact area with the conveyor belt is small, The surface temperature of the conveyor belt can be controlled between 60 ℃ and 80 ℃. But when the conveyor belt conveying cement powder in the process, the material temperature and conveyor belt surface temperature will be little difference.

2. The temperature on the surface of the conveyor belt seriously affects the service life of the heat-resistant conveyor belt, and also affects the peeling off of the cover rubber and the delamination of the belt core. Therefore, when selecting the heat-resistant conveyor belt, it is very important to consider the temperature on the surface of the conveyor belt, as well as the ambient temperature and whether the conveyor belt can be fully cooled when it returns; In addition, the conveying speed and the distance between the center line of the conveyor belt need special attention; In order to ensure the long service life of heat-resistant conveyor belt, the thicker cover glue is the key factor.

3. Teflon high temperature resistant conveyor belt Teflon conveyor belt is also known as Teflon conveyor belt, Teflon conveyor belt, PTFE conveyor belt and high temperature resistant conveyor belt. Teflon conveyor belt is divided into Teflon mesh conveyor belt and Teflon high temperature cloth. Both of them are made of teflon resin coated with glass fiber cloth as the base material to make Teflon (PTFE) conveyor belt base cloth.

characteristic:

1, for low temperature -70 degrees, high temperature between 260 degrees, has weatherability, anti-aging. After practical application, not only the strength will not be reduced, but also the weight will not be reduced if it is placed at 250 ℃ for 200 days; After 120 hours at 350 ℃, the weight is only reduced by about 0.6%; The original softness can be maintained at - 180 ℃.

2. Teflon conveyor belt non adhesion: not easy to adhere to any substance. It is easy to clean all kinds of oil stains, stains or other attachments on its surface; Almost all adhesive substances such as paste, resin and coating can be simply removed;

3. Resistant to chemical corrosion, strong acid, alkali, aqua regia and various organic solvents.

4. Teflon conveyor belt has good dimensional stability (elongation coefficient less than 5 ‰) and high strength. It has good mechanical properties.

5. Anti bending fatigue, can be used for smaller wheel diameter.

6. Drug resistance, non-toxic. It can endure almost all medicaments.

7. Fire retardant.

8. Air permeability --- the air permeability of conveyor belt, reducing heat consumption and improving drying efficiency.
