In industrial production, we will encounter some industrial products that need to be operated under high temperature conditions. Then this will lead to how to deal with these high temperature products, and we can't take them by hand. So what should we do? At this time, we need a heat-resistant conveyor belt. Then the question is, how can I know that this conveyor belt can be heat-resistant? The following small series will tell you how to distinguish the heat-resistant conveyor belt.
First of all, how to distinguish the quality of heat-resistant conveyor belt
The application of heat-resistant conveyor belt is mainly reflected in the metallurgy, construction and other industries, conveying high temperature materials such as sintered coal mine, coke and cement clinker. The structural materials are used in domestic high temperature resistant canvas, and the special formula design is well solved. The problem of poor adhesion and poor adhesion between layers. It has the characteristics of light weight, long service life and good high temperature resistance.
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; the temperature of the material conveyed by the conveyor belt and the temperature of the conveyor belt surface should be based on the nature and composition of the material itself. The shape of the surface structure and the size of the particle size vary. For example, when the material temperature of a large area is 150 degrees (coke or sintered ore) and the contact area with the conveyor belt is small, the temperature of the surface of the conveyor belt can be controlled at 60 degrees. Between 80 degrees. However, when the conveyor belt transports the cement powder, the temperature of the material and the temperature of the surface of the conveyor belt are very small.
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. Therefore, when selecting the heat-resistant conveyor belt, it is important to consider the temperature of the surface of the conveyor belt. Also, whether the ambient temperature and the conveyor belt can be fully cooled; in addition, the conveyor speed and the centerline distance need to pay special attention; to ensure a long service life of the heat-resistant conveyor, thicker Cover rubber is a key factor.
3, Teflon high temperature conveyor belt
Teflon conveyor belt is also known as Teflon conveyor belt, Tiefulong 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 coated with Teflon resin on a glass fiber cloth to form a Teflon (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.
