What is a belt vulcanizer?
Hot vulcanize gadget is specifically product of aluminum and used for the splicing of rubber conveyor belts together with EP, NN and Steel wire belt etc. It may be extensively utilized in metallurgical flora, mines, electric powered energy flora and docks etc.
Hot vulcanizing is a technique of restore that makes use of each heater and pressure bag jointing restore substances with compromised sections of the belt. The belt need to be wiped clean and freed from all oily, greasy materials earlier than starting.
How do you Vulcanise a conveyor belt?
- Select the right machine and tools.
- Master the correct joint method
Vulcanisation is an involved procedure that can offer a smooth splice with minimal risk of snagging, tearing and other harmful wear to the belt.
There are two types of vulcanising processes, hot and cold. Each process requires unique tools and an intimate knowledge of the rubber bonding process.Hot vulcanisation splices are heated and cured under pressure with a vulcanising press.
The process of hot vulcanising involves using a heated press to splice in a new section of rubber. A hot vulcanised joint will be stronger and longer lasting than those formed by other methods. Belts that have had vulcanised repairs are easier to keep clean as there are no gaps or holes for bacteria to establish in.
Cold vulcanisation does not use a press, but uses a bonding agent that causes a chemical reaction to splice the two belt ends together. This chemical reaction ensures that cross-connections between different monomer chains are created. This splices the two ends of the belt together.
Hot and cold splicing of belts require meticulous preparation to prevent contamination of the splicing area. Cold splicing requires relatively warm conditions and low moisture to ensure the cold vulcanizing cements work optimally.
We do not recommend cold bonding in most instances as we see a large amount of cold bond joints that have prematurely failed.
