How to identify the heat-resistant conveyor belt?
1. Choosing a suitable heat-resistant conveyor belt depends not only on its thermal strain but also on the chemical mechanical strain capacity; conveyor belt
The temperature of the material to be conveyed and the temperature of the surface of the conveyor belt should be based on the nature, composition, shape of the surface structure and particle size of the material itself.
The size of the material changes, such as a large area of material temperature of 150 degrees (coke or sintered ore) and the contact surface with the conveyor belt
When the product is small, the temperature of the conveyor belt surface can be controlled between 60 and 80 degrees. But when the conveyor belt transports cement powder
During the process, the temperature of the material will be very different from the temperature of the surface of the conveyor belt.
2. The temperature of the surface of the conveyor belt seriously affects the service life of the heat-resistant conveyor belt, and also affects the peeling of the rubber cover and the delamination of the core.
In selecting a heat-resistant conveyor belt, it is important to consider the temperature of the conveyor belt surface, as well as the ambient temperature and whether the conveyor belt can return.
Sufficient cooling; in addition, the conveyor speed and centerline distance need to pay special attention; to ensure the heat-resistant conveyor belt
With a long service life, thicker cover rubber is a key factor.
3, Teflon high temperature conveyor belt
Teflon conveyor belt, also known as Teflon conveyor belt, Tiefulong conveyor belt, PTFE conveyor belt and high temperature resistant conveyor belt, Teflon conveyor belt
Teflon mesh conveyor belt and Teflon high temperature cloth, both of which are coated with Teflon resin on glass fiber cloth.
Fluorocarbon (PTFE) conveyor belt base fabric.
1, for low temperature -70 ° C, high temperature 260 ° C, with weather resistance, anti-aging. After practical application, such as at 250 ° C high temperature
Continued to be placed for 200 days, not only the strength will not become lower, but also the weight is not reduced; placed at 350 ° C high temperature for 120 hours, the weight is only reduced
Less than 0.6%; at -180 ° C ultra-low temperature and can maintain the original softness.
2, Teflon conveyor belt non-adhesive: not easy to adhere to any substance. Easy to clean all kinds of grease, stains or other adhesions attached to its surface
Almost all adhering substances such as paste, resin, paint, etc. can be easily removed;
3, resistant to chemical corrosion, can withstand the corrosion of strong acid, alkali, aqua regia and various organic solvents.
4. The Teflon conveyor belt has good dimensional stability (extension coefficient less than 5‰) and high strength. Has good mechanical properties.
5, anti-bending fatigue, can be used for smaller wheel diameters.
6, drug resistance, non-toxic. Almost all drug items are available.
7, fire retardant.
8. Breathability---The air permeability of the conveyor belt, reducing the heat source cost and improving the drying efficiency.
