Repair materials for steel cord conveyor belt's damages or tears

Comparing to other belt,steel cord conveyor belt conveyor belt requires larger tensile strength,so the repair requirements naturally higher if it damaged or tear. The traditional way is mostly hot vulcanizing, but due to the cumbersome operation of the hot cure method, repair efficiency is low, and now the large mining more use of quick and easy way to repair cold vulcanization on-site operation and treatment.

Cold vulcanization repair-the choice of repair material is crucial when it comes to repairing a conveyor belt, whereas a steel cord conveyor belt requires a higher degree of repair material when it is cold vulcanized.

Glue needs to have higher adhesion.
Ordinary glue adhesion is generally not enough to meet the bonding requirements, usually after bonding degumming,the cracking happens. Is currently using more than a US-based cold curing conveyor belt repair glue CV-2000. 
CV-2000 cold vulcanized glue, curing speed of more than 3 times the ordinary glue, adhesive strength after curing at 10000cps, and the same level of heat-curing glue adhesion. Fully meet the tension after the boot with steel wire requirements. 

Repair patch to achieve the maximum with the glue. 

As a bond in the tearing of the conveyor belt repair patch, to achieve the best match with cold vulcanized glue. Repair patch, then the market is more commonly used in two ways, that is, ordinary repair strip and CN semi-sulfide patch. Among them, the advantages of CN patches are obvious. 

With the CN layer repair strip can be coated with cold vulcanized glue, and vulcanized rubber between the self-curing cross-linking reaction, the shear strength of up to 16N / mm2, can effectively guarantee Bonding effect after steel band repair.

Steel cord conveyor belt torn repair site operations processes

The use of angle grinder with the appropriate degree of wear tungsten steel grinding disc on the damaged parts polished;
Brushing cleaning agent on damaged parts, wash away the surface impurities, oil.
Damaged parts painted cold vulcanized glue, to be dried and then brush it again, while the adhesive surface of the repair brushing again glue.
The repair patch posted in the damaged parts, the use of compaction roller back and forth rolling, discharge excess air.
