Features and Preponderances of the Belt
Bone materials with high tensile strength
The solid woven belt use various high tensile strength chemical fibers and a yard wide cotton yarn as bone materials, and apply the advanced textile structures of France Depreux. The special multiple tiers integrate with each other so as to reach tensile strength and weft&warp tear resistance,light carcass weight,and save the power energy for transportation.
Advanced soakage technology
The unique solid woven belt soakage technology can make PVC paste soak well. Thus,the paste and solid woven fabric become the all and the one,which ensures the belts impact resistance property.
Cover rubber with excellent properties
The special cover rubber of PVG solid woven belt has excellent properties,which represent at excellent physical properties on the basis of ensuring the safety propeties. Thus,the cover rubber can give the carcass first-rank protection.
Excellent flame resistant property
The excellent flame resistance property of PVG solid woven belt can ensure that it can use safely underground coal mines.
PVC BELT: Used for conveying material up to 16ºC inclination under dry conditions.
PVG BELT:With rubber cover,suitable for conveying water material up to 20ºC inclination.
Market:
Coal mines,power stations,chemical and metallurgy industries.
