b: > : : >4. Principle of buffer bed
: : ><:>
r : > : : >Domestic manufacturers choose materials that are not in direct contact with the conveyor belt, mainly using three methods: ultra-high molecular weight polyethylene board, polyurethane, and ceramics. Ceramics have good wear resistance, but the friction coefficient is extremely high, which can easily cause scratches, heat, and smoke on the conveyor belt. It is extremely harmful. The ceramic sheet itself is suitable for lagging of conveyor belt drive rollers in muddy environments. The manufacturers who choose this surface material basically do not understand the use environment and conditions of the buffer strips and make them blindly. Polyurethane has good bonding performance and requires low bonding technology. However, the material is easy to hydrolyze and has poor impact resistance. It is still prone to delamination and delamination after long-term use. Ultra-high molecular weight polyethylene has the lowest friction coefficient and excellent self-lubricating properties, which facilitates the passage of conveyor belts. It is very suitable for the surface material of buffer strips under harsh working conditions. However, it has higher requirements for the manufacturer's process and is difficult to bond with rubber without special treatment. .

b: > : : >5. Description of metal skeleton
: : ><:>
b: > : : > Whether internationally or domestically, there are roughly two ways to fix the bed frame without buffer strips, one is steel hooks, and the other is aluminum alloy connecting frame hooks. The steel structure is strong and durable, and does not deform. It is good Fixed poles will gradually replace aluminum alloy poles. In terms of scope of use, steel poles can be used both underground and above. However, aluminum alloy structures are prohibited from using this type of connection mechanism underground both internationally and in my country. Therefore, any company claims that aluminum alloy structures can be used underground. Using it underground and issuing relevant flame retardant certificates are deceptive to consumers. In the domestic market, it is not that manufacturers are unwilling to adopt this kind of steel pole structure, but that there is no such technology. From the perspective of the connection structure, this connection method requires higher bonding performance of rubber stainless steel poles, and special hot vulcanization must be used. Bonding technology (different from general bonding methods)
