The whole core fire retardant conveyer belt because suitable for downhole operation and much loved mine production enterprises, nowadays, people in order to better play its flame retardant, explosion-proof, anti-static advantages, continue to conduct research and development of its material, make heart plant conveying fabric material with continuously new industrialization, industrialization.

The strength of the whole fabric core conveyor belt mainly depends on the whole belt core material. At present the domestic whole belt core of the latitude and longitude are based on polyester / cotton yarn or for cotton fiber / cotton yarn, so the belt body thickness and weight, low intensity, while the foreign general use polyester or aramid fiber as warp, weft as the cotton fibers and cotton yarn, and the belt core thin, light weight, high strength. With the development of high performance, thin and light weight of the whole belt core strength more than 3000N/mm should be the preferred option of aramid fiber as warp threads, so that the belt body of thin, light weight. In the vertical dipping and plasticizing, the conveying strength greatly improved belt, prolonging the service life. Effect of PVG glue is covered the whole fabric core flame retardant conveyor belt service life of important factors. At present the domestic ordinary selection of chloroprene rubber, nitrile rubber and polyvinyl chloride as main material covering the adhesive has been widely used abroad, and chlorinated polyethylene and polyethylene chloride and vulcanized thermoplastic rubber material of elastic body model, especially the use of thermoplastic elastomers do cover the glue can adopt extruder dynamic vulcanization molding adhesive process. PVG realize the whole fabric core conveyor belt continuous production, the production efficiency is greatly improved, and the energy can be saved and reused, so it is a development trend in the future.
