Abstract
A process for producing polymer pre-stretching gridiron used for earth andwithout punching, which is characterized in that the process comprises: (1) automatically fully stretching the polymer thin plates by a pre-stretching machine so as to re-align the polymer molecules to form reinforced plate with high tensile strength, in which the production of reinforced polyethylene plate comprises introducing the polyethylene into a molding machine and melting the polymer at 180 deg.C and extruding the polymer at 1.5 m/minute to form continuous plate with a dimension of 80 mm by 5 mm and cooling the extruded plate in a cool water tank and transporting the plate at a speed of 1.5 m/minute by a rolling wheel into a hot water tank which is at 95 deg.C to heat the plate and the heated plate is automatically stretched by a stretching wheel at 10 m/minute to re-align the molecule's long bonds to form reinforced plate and stabilizing the stretched in a stabilization water tank at 80 deg.C to retract the plate for 10% to form a reinforced plate with a dimension of 25 mm by 1.5 mm; (2) interleaving the reinforced plate according to the specified width and gluing or hot-melting the junctures of the interleaved net to form the polymer pre-stretching gridiron.
