RUBBER MANUFACTURE

Sand blasting is a metal surface mechanical treatment technology widely used in rubber production. The basic principle of sand blasting is to use sand, steel balls, glass beads, etc., with compressed air of 0.5 0.6MPa, and spray it onto the surface of the workpiece to be treated, and use high-speed jets of sand, steel balls or glass beads to remove the surface of the workpiece. Rust, oxide and other contaminants make the bond between the rubber grommets and the metal stronger... The metal skeleton after sandblasting should be bonded to the rubber product as soon as possible to avoid secondary oxidation and contamination of the surface... Metal oxide vulcanization is of great importance to chloroprene rubber, chlorobutyl rubber, chlorosulfonated polyethylene, chlorohydrin and polysulfide rubber, especially chloroprene rubber, which is commonly vulcanized with metal oxides. When chloroprene rubber is vulcanized, the allyl chloride structure produced by 1,2-polymerization is used, and..
