Thermal vulcanization of steel wire rope core conveyor belt
Steel cord conveyor belt heat vulcanization must use belt vulcanizing machine, belt repairer heat vulcanization and joint form and joint length. Steel cord conveyor belt must be hot vulcanized. The joint length and joint geometry of the joint should be based on the diameter and spacing of the rope. The breaking force of the wire rope and the extraction force of the rubber bond shall be such that the wire rope in the joint shall have a certain overlapping length, so that the adhesion of the steel wire core and the glue at the joint is greater than the breaking force of the steel wire rope.
If the spacing of the wire rope can be placed in a steel wire rope and the necessary intermediate glue (1.5 ~ 5mm), then the connection of the steel wire core conveyor belt has a good state, can be level-lapped, if the wire rope spacing is not enough to place the wire rope and conductive tensile The middle glue of the force requires multi-level bonding.
The conveyor belt is made of high-molecular materials such as natural rubber and neoprene, as well as composite rubber products made of core materials such as steel wire rope, cotton, polyester, nylon, etc. It is a material conveying device widely used in metallurgy, electric power, coal, In industries such as cement.
The conveyor belt is generally composed of a core (also known as a reinforcing layer or a tensile layer), a cover rubber and a side rubber.
The core is the skeleton of the conveyor belt, which bears all the tension (load) when the conveyor belt is working. The core should have a high strength. The core material of the conveyor belt includes steel wire rope, cotton, vinylon, nylon, polyester and the like.
The cover rubber is the protective layer of the conveyor belt, and the protection belt core is not affected by the impact, abrasion and corrosion of the material during operation. The side in contact with the material is called the upper cover rubber, which is the working surface of the conveyor belt; the other side is called the lower cover rubber, which is the non-working surface. Usually, the cover rubber is thicker than the cover rubber. In addition to abrasion resistance, impact resistance and tear resistance, the cover rubber also requires acid resistance, alkali resistance, heat resistance, cold resistance, flame resistance, antistatic, etc. according to the nature of the material. The cover rubber is generally smooth and sometimes adapted to high inclination. For the needs of the conveyor, various patterns are produced on the surface of the cover rubber.
The edge glue refers to the rubber edge strips on both sides of the conveyor belt to enhance the wear resistance of the edge and prevent the early damage of the belt body caused by the broken edge.
