At present, major industrial and mining enterprises adopt cold vulcanization repair method, which does not require large equipment and a lot of manpower and material resources, and can be started in a short time after repair, which is also an important reason for choosing this method for construction.
Of course, according to the specific situation of damage, the specific operation mode is different.
If there are surface defects, cold vulcanized rubber mending agent can be used to fill them on site. When operating, just fill the damaged parts with the rubber mending agent after mixing and stirring, and then scrape it off with a scraper, which is quite simple and quick.
If the belt is cracked, it is usually operated with cold curing glue and RIT belt repair strip, in which the cold curing glue is used for bonding between the belt and the repair strip, and the repair strip is used for bonding the cracked part to ensure the smoothness and integrity of the repair part.
In the cold vulcanization mode, the requirement for more glue is naturally much higher because it does not depend on mechanical equipment. When choosing, the construction personnel should carefully select and compare. At present, the imported two-component cold viscose water, such as sk3 13, is mainly selected as the supporting curing agent. Bonding effect and curing speed have considerable advantages, which can be used for comparison and selection.
For field operation, it is necessary to polish the torn part and apply cold vulcanizate twice. When the glue sticks to the back of the finger slightly, it is not difficult to stick the glued patch on the damaged surface, and then roll it firmly with a compaction roller to discharge excess air.
