The high-temperature resistant conveyor belt molding process is to make each part of the product into a certain prototype through the method of pasting and pressing, and then vulcanize to obtain a rubber product with a certain shape, thus forming a conveyor belt.
High-temperature resistant conveyor belts are mostly complicated in shape and structure. Some conveyor belt components include various textiles, tapes, and metal materials in addition to rubber. There are also many parts that make up a product. The molding process is like the assembly process of machine manufacturing. Through molding, the various components are combined into a whole with a certain shape, and the skeleton, the upper and lower covering glue are tightly adhered, so that the conveyor belt skeleton and cover The glue layer plays its best role.
Rubber products will gradually become soft due to the effects of oxygen, ozone, price-changing metal ions, heat, light, high-energy radiation, mechanical stress, etc. and other chemical substances during processing and long-term storage and use. Tackiness, or hardening, embrittlement, cracking and other phenomena, so that its physical and mechanical properties are deteriorated so that it loses its elasticity and loses its use value. The aging phenomenon of rubber is an irreversible change process. Its essence is the molecular structure of rubber. 、 Physical and biological factors such as oxidative degradation reaction or structuring reaction, reducing the reaction will reduce the average molecular weight of rubber and strength, so it will become soft and sticky, and the structuring reaction is to further branch the vulcanized rubber The joint will gradually lose the three-dimensional network structure, so the strength will decrease, and the surface will be hardened, brittle and cracked and lose its elasticity.
