Concrete pump rubber hose
Applications
1. Useful in various kinds of sand blast machines.
2. In shipbuilding industry, it can be used for removing rust and enhancing adhesion before hull painting.
3. Other industries: Oil tank rust-removing and reinforcing; corrosion protection in gates of bridges and irrigation works; rustproof, de-oxidation, and paint removal for metallic parts.
Main structure
Inner layer: Using natural rubber, polyurethane rubber and other composite rubbers as major materials, with the addition of special reinforcing agent.
Framework: The fabric reinforced sand blast rubber hose employs fine fabric (canvas) or chemical fabric cloth as reinforce layer; thus having good flexibility and loading-bearing capacity.
Outer layer: Using natural rubber and other composite rubbers, exhibiting good wear- and oxidation- resistance, long useful life and good view.
Main types
Normal sand blast rubber hose; rubber hose for waterway desilting, cementing pump truck, concrete, grout, sediment, coal injection truck, bulk cement truck, sandblast, big inch grout hose, white powder and dredging.
Blasting materials
Quartz sand, steel shot, sediment, ball bearing, cement powder, cement concrete, dry powder mortar, coal fines, carbon powder, and mineral powder.
