\ PVC pipe through the wall / cement support pipe, broken material available in PVC plastic, white pipe broken material, ash pipe broken material, milling material Qingdao PVC pipe production line, or PVC powder plus calcium extrusion casing PVC pipe production line Suppliers, for the production of PVC pipe through the wall PVC pipe production line, carpentry casing, cement support pipe, casing pipe steel carpentry, general models: 16 #, 18 #, 20 #, and other types of steel casing . Host structures by the screw, barrel, transmission, barrel heating and cooling system, exhaust composition, dosing device, rack, head joins the body, electrical control boxes and other main parts. 1, it is the completion of a plastic screw conveyor and plasticized key parts, when the barrel is rotated back into the powdered plasticizing nose, so as to achieve the purpose of compaction, melting, homogenization of mixing. Screw thread on the segments are composed of different pitch in order to achieve better conveying, compacting, kneading and plasticizing, and achieve the exhaust gas, the purpose of dewatering. 2, barrel barrel is plastic and screw parts to accommodate its hole shaped like a "∞" PVC pipe production line price, which direct friction with the plastic and screw. Material is nitrided steel barrel, after nitriding, the bore surface with high hardness and good wear resistance and corrosion resistance. Surface of the barrel is provided with four sets of electric heater, the heat transmitted through the plastic barrel, the plastic melt plastics. Each group has a heater temperature measurement points, control the heating temperature of the barrel.
