1. Joint method: Rubber conveyor belt joint method: mechanical joint, cold bonded joint, hot vulcanized joint and other commonly used methods. Mechanical joint generally refers to the use of belt buckle joint, which is convenient and economical, but the efficiency of the joint is low and easy to damage, which has a certain impact on the service life of rubber conveyor belt products. In the joints of PVC and PVG integral core flame retardant and antistatic rubber conveyor belts, the joint method is generally used for products below grade 8 belt.
2. Cold bonded joints: that is to say, cold bonded adhesives are used for joints. This kind of joint method is more efficient and economical than mechanical joint. It should have better joint effect. However, in practice, it is not very stable because the process conditions are difficult to master and the quality of adhesives has a great influence on the joint. Thermal vulcanized joints have been proved to be the most ideal joint method, which can ensure high joint efficiency, stability, long service life and easy to grasp. However, there are some shortcomings, such as troublesome process, high cost and long joint time.
3. Joints of layered rubber conveyor belts: mechanical joints, cold-bonded joints and hot-vulcanized joints can be used as required. Generally, the cold bonded and hot vulcanized joints adopt the stepped structure joints.
4. Joints of PVC and PVG Whole-core flame-retardant rubber conveyor belts: Because the structure of the Whole-core belt is special and the joints are not easy, most of them adopt mechanical joints, i.e. belt buckle joints. However, for rubber conveyor belts above grade 8, in order to ensure the effect of joints, hot vulcanized joints are generally used. The joints are all finger joints. The process of hot vulcanization joint of PVC and PVG whole core flame retardant rubber conveyor belt is complex, and the requirement for equipment is relatively high.
