In the transportation system of belt conveyor, it is very important to carry out roller lagging and conveyor belt repair regularly, due to the defects of hot vulcanization lagging and repair, such as high operation difficulty, long construction time, need for large-scale vulcanization equipment, and inconvenient transportation, although the bonding strength of the hot vulcanization process is very high, the more convenient and efficient cold vulcanization bonding technology has become the first choice for the repair of roller lagging conveyor belt.
Cold vulcanization repair requires the skills of the construction personnel and the materials used, and the selection of the right adhesive is a top priority.
So what kind of adhesive should we choose?
The first thing to understand is that different substrates require different adhesives, and pulley lagging and conveyor belt repair are mainly the bonding between metal and rubber, rubber and rubber. After determining the base material, it is also necessary to take into account the working environment, the roller and conveyor belt are constantly moving and vibrating during operation, so the adhesive should also have good toughness and tear resistance after curing, so as to avoid tearing and opening the adhesive surface due to complex stress and vibration during the operation of the conveyor.
After these two difficulties are solved, the adhesive may need to have corresponding water, oil, acid and alkali corrosion, heat and oxygen resistance, flame retardant, cold resistance, high temperature resistance and other properties according to the working conditions.
