Any product can only be used and maintained to ensure its basic service life. Unreasonable damage to the machine is very large.
So what are the factors that affect the service life of PVC conveyor belts?
A is made of warp, latitudinal filaments and covered cotton woven into a dense core;
B is specially coated with PVC material to achieve extremely high bond strength between the core and the cover rubber;
C specially formulated cover rubber; thus making the belt impact resistant, tear resistant and abrasion resistant.
The flame retardant performance of PVC conveyor belts is mainly reflected in the following aspects:
Roller friction: the surface temperature of the drum is not more than 325 °C
Blowing lamp burning: The flame time of the full-thickness test piece burner is not more than 3.0S, and the average coverage of the cover layer is not more than 5.0S.
Propane combustion: lossless length greater than 250mm
Surface resistance value: the upper and lower average values are not more than 3.0×10
