Cold Vulcanizing Solution – Definitive Guide
During the bulk material conveying of the belt, various damages may occur due to material dumping, falls, such as longitudinal tearing, edge damage, gouged, deep punctured, and so on. All the damages can be repaired by the cold vulcanization solution, it is the most efficient repair method so far.
What is Cold Vulcanization?
Cold vulcanizing is to use vulcanized material such as patches and strips to repair a conveyor belt. Cold vulcanization does not use a press but uses a bonding agent like TRS cold adhesive, which causes a chemical reaction to splice the two belt ends together. Cold vulcanization means that you can finish your vulcanization at ambient temperature. You can often see it on conveyor belt jointing, pulley lagging, conveyor belt repair. Different from hot vulcanization, cold vulcanization allows your conveyor only 2-3 hours of downtime, which greatly reduces the maintenance cost and improves the production efficiency. In conveyor maintenance, cold vulcanization is a perfect solution for emergency conveyor belt repair, it suitable for conveyor belt repair includes longitudinal breaches, damaged topcoats, damaged edges of the belt, or bonding rubber to steel surface too.
Benefits of Cold Vulcanization
Cold vulcanization allows you to finish your conveyor belt repair in 2-3 hours, and the repair process is easy. Simple and fast repair greatly reduces the loss caused by conveyor downtime.
As there is no requirement of the vulcanizing press, and the cold bonding material is cheap, your cold vulcanization solution needs less cost than hot vulcanization. Beltcare cold vulcanization for conveyor belt repair just need 1-2 engineer, you can save much labor cost.
Besides, low inventory is another advantage of cold vulcanization. One cold vulcanizing cement can be used for conveyor belt repair, cold splicing of conveyor ends, pulley lagging at the same time. And one roll of conveyor belt repair tape can be used for several times of conveyor belt repair.
With these advantages, cold vulcanizing has been the main stream conveyor belt repair methods.
Conveyor Belt Cold Vulcanizing Procedure
Your operating steps will directly affect the repair effect, please do it strictly according to the following steps:
You should calculate the grinding area first, the grinding width and thickness should be consistent with the repair strip. Then use the Angle grinder and tungsten steel polishing plate to polish the damaged surface. Finally, sweep away the residue, clean it with a cleaning agent, and dry it.
After mixing the cold curing adhesive and curing agent in proportion, evenly brush the mixture on the adhesive surface, wait some minutes, and test it with the back of your hand. If you feel slightly sticky when touching the surface, brush it again. The blue CN layer of the repair strip also needs to brush a layer of mixture.
If you feel slightly sticky when touching the surface again, it’s time to bond it. Please paste the patch strips from one side and use a compacting roller to compacting them from the middle to the sides, it can drain the air. Finally, brush the joint evenly on the surface with the mixture.
Everything is ok, then wait 2 hours for its natural vulcanization. At this step, you can use the conveyor belt for your projects. If you can wait for 4-8 hours, it can achieve the best repair effect.
Cold Vulcanizing Kit
A cold vulcanizing kit for conveyor belt repair includes conveyor belt repair tape, cold vulcanizing cement, and clean solvent. In your conveyor belt repair, you still need other tools including an Angle grinder, tungsten steel polishing plate.
Conveyor Belt Repair Tape
Conveyor belt repair tape is often called conveyor belt strip or rubber repair strip, it can be divided into standard repair strip, diamond belt repair patch, and fabric-reinforced repair strip.
They are made of synthetic rubber, which compounds with superior quality neoprene-based bonding layer on one side. Conveyor belt repair tape is highly tensile strength, high wear-resistant, and 60 Duro natural rubber strips designed to repair the damage of conveyor belt covers. It is one of the main products in a cold vulcanizing kit.
Cold adhesive is also called cold vulcanizing cement, it is suitable for the cohesion of rubber-rubber, rubber-metal, rubber-fabric & fabric-fabric. Cold vulcanizing has a superb performance to be used for repair of the conveyor belt, cold splicing of conveyor ends, pulley lagging, etc.
Cold vulcanizing is another necessary product in a cold vulcanizing kit. Beltcare distributes TRS cold adhesive with hardener, high quality at a reasonable price. Fire Resistance, Wear Resistance (Conform to the 1000M standard)
Cleaning Solvent With Hardener
Cleaning solvent is used to remove the oil and dirt from rubber and metal surface so as to provide a clean and dirt-free environment for intensive bonding. We distribute cold adhesive of high quality at a reasonable price, including Germany TRS cold vulcanizing cement, PU adhesive, cleaning solvent, metal premier, etc.
Cold vulcanization repair is the mainstream conveyor belt repair method at present, it can fix most conveyor belt damages. Besides, it is cheap, fast, efficient, and easy to install, your conveyor belt will be fixed in one hour. In the past 20 years, Beltcare has established a whole supply chain for cold bold repair material, we can provide you a great quality cold bold repair material at a competitive price
