Waterproof Plate is manufactured by domestic advanced technology of two co-extruded single-screw extrusion, joining reinforcer, antioxidant in the materials of resin EVA, to form plate through melting, plastication, extrusion, pulling etc processes. Waterproof plate also could be heat sealedtogether with geotextile (signal layer) to form composite waterproof plate.
The process of extrusion and rolling can be used as well, which means: first colophony is plasified through extruder; second peptized which is extruded from combines with hanging stripinto one and is rolled and coolednto gloss lamination, or combines with geotextile and is rolled and cooled into compound waterproof roll material.
