How to repair Teflon conveyor belt Repair wear? Many people must not know. Under high-speed operation, Teflon high-temperature cloth Conveyor belt It often produces severe friction, so it is common to have certain wear under long-term use. So how can we repair the wear? Let's have a look.
How to repair the wear of Teflon high temperature cloth conveyor belt
The wear repair method of Teflon high-temperature cloth conveyor belt is as follows:
1. Rubber repair glue covering repair method
The rubber repair glue produced at home and abroad is two-component polyurethane glue. When using, pour them together and stir them evenly, then fill them on the surface to be repaired. After curing within a certain period of time, they become elastomers similar to rubber. The curing time is generally 05-6h, which is related to the ambient temperature during curing. The cured gel has good bonding performance with the surface of the conveyor belt, and the experimental data in the laboratory shows that it can reach 6kn/m180 degree peel strength), so the bonding and sealing of the repair surface is good, and there will be no water vapor entering the bonding surface and rusting the wire rope.
More favorable, its abrasion resistance is quite excellent, and the Akron abrasion value is 4-6 times lower than that of rubber. The superior wear resistance is the key requirement for the local wear repair of conveyor belt. To sum up, this method is a very effective way to repair the local wear of steel rope conveyor belt.
2. Rubber patch
The rubber patch method with German technology has the advantage of fast repair speed. After polishing and cleaning the place to be patched, apply adhesive and glue, and then start the machine. The disadvantage is that the rubber will fall off after 60-90d operation. The bigger problem is that if the conveyor belt operates in a wet environment, water vapor will accumulate in the gap of the bonding surface and rust the steel wire rope. The steel wire rope will rust and break after a long time. And even cause the sudden fracture of the whole conveyor belt. In addition, the cost of this repair method is also high.
3. Local rubber vulcanization
Use a small vulcanizer to vulcanize the local damage. Due to the limitation of the size of vulcanizer, the repair speed is only about 05m/h. This method is not suitable for long-distance repair.
