The Key raw materials
Binder resin is the key to this product, is the smooth realization of the pipe pressure process stress transfer, pipe composite key materials, the performance of the binder resin largely determines the level of quality of the product, our company has a targeted raw material design and development platform to improve the binder resin and process, equipment matching targeted.
Plating can play a role in corrosion protection, and at the same time play a role in enhancing the shear strength of steel wire and bonding resin, through data testing and comparison found that the average value of shear strength of tin bronze is 20.69MPa, brass is 11.42MPa, there are large differences in the shear strength of steel wire with different plating and bonding resin, so we chose to use tin bronze plated steel wire as a pressure-bearing substrate.
