Background

In the domestic waterproof industry, a copper foil is mostly adopted to be made into a copper foil base by bonding polyester base fabric through glue or thermosol and the like, and basic copper carbonate generated by slowly oxidizing the copper foil of the copper foil base is utilized to block roots. From the production perspective, the current copper foil polyester tire has reduced production efficiency due to the barrier permeability of the copper foil surface.

Even if the polyester tire base fabric is broken outside the elongation range, as long as the asphalt layer wrapped outside the tire base fabric is not broken, copper particles still exist near the asphalt, and basic copper carbonate can be generated in the environment reached by the root system by the existence of copper particles and the existence of copper atoms, so that the polyester tire base fabric has more complete root-resisting and root-resisting effects.
