PVC single wall corrugated pipe production process edit this section by a certain percentage will be added to the appropriate PVC compounding additives, generally use the "Z" type kneader or high-speed kneading machine to mix evenly, the extruder using a twin-screw granulation or powder a molding material. Rpm using a single screw extruder machine is generally 30 ~ 60r / min, head pressure control about 36 ~ 54MPa. To fully plasticized material, the use of compressed air to blow into a bubble freedom. After extrusion stability, the ripple molding and extrusion die device inserted, both to ensure that the centerline distance should be more than a pair of positive molding module inside the extrusion die insert mold, in order to ensure full closure after forming the upper and lower module products. Sequence upper and lower mold ring groove must be aligned, not misplaced. Speed ??traction control in general 6 ~ 10m / min or so. Inflation pressure with full-blown products annular groove principle, which normally takes 0.15MPa. Mold temperature control in about 45 ~ 60 ℃ pe single wall corrugated pipe supply, before opening moldings facilitate basic shape pe standard single wall corrugated pipe, corrugated pitch avoid winding stretch. Extrusion feed zone temperature control 145 ~ 160 ℃, the compression section 165 ~ 175 ℃, metering section 175 ~ 185 ℃, the head 175 ℃ ~ 180 ℃, the die 170 ~ 180 ℃. PVC single wall corrugated pipe and characteristics of major equipment edit this section extruder generally ranging from deep pe equidistant single wall corrugated pipe equipment, gradient-type screw (see soft poly ethylene pipe extruder catch). Corrugated molding device consists of mold, transmission and control system. Which is composed of dozens of mold on the top and bottom off successive blow mold composed of upper and lower mold to crawler were fixed at two drive belt. When the transmission to drive the mold is rotated, the upper and lower mold repeated closing - opening action. Constitute a closed mold cavity forming a circular pipe, blow molded bellows after the mold is opened pe single wall corrugated pipe, make products stripping. Corrugated molding equipment products also play a role in shaping and traction.
