Wide-format transparent film can be used for greenhouses, plastic greenhouses and mulch; biaxially stretched film, due to its heat-shrinkable characteristics, can be used for shrink packaging. (3) PVC foam products When soft PVC is mixed, an appropriate amount of foaming agent is added to make a sheet, and then foamed into foam plastic, which can be used as sandals, insoles, foam slippers, shockproof buffer packaging and other materials. (4) It can also be used to make leather bags, suitcases, book covers, sofas and car cushions, etc., and can also be made into floor leather as a paving material for buildings. (5) PVC transparent sheet can be made into thin-walled transparent containers by thermoforming and can also be used for vacuum blister packaging such as moon cake packaging boxes. It is an excellent packaging material and decorative material. (6) Other PVC applications use an extruder to process PVC into hard special-shaped materials and use them for door and window assembly. In some countries, doors and windows assembled with PVC hard profiles have jointly occupied the door and window market with wooden doors and windows, aluminum windows, etc. Prodection details 1. Raw material mixing is to add PVC stabilizers, plasticizers, antioxidants and other accessories to the high-speed mixer in proportion and process. The material is heated to the set process temperature by self-friction between the material and the machinery, and then the material is reduced to 40-50 degrees by the cold mixer so that it can be added to the hopper of the extruder. 2. Part of the second-hand pvc extruder is equipped with a quantitative feeding device, so that the extrusion volume and the feeding volume can be matched to ensure the stable extrusion of the product. Due to the characteristics of the tapered screw, the feeding section has a larger diameter, which is more conducive to the heat transfer area and shear speed of the material. The small diameter of the screw in the metering section reduces the heat transfer area and the shear speed of the melt, so that the melt is extruded at a lower temperature. When the screw rotates in the barrel, the PVC mixture is plasticized and pushed to the nose to achieve compaction, melting, mixing and homogenization, and to achieve the purpose of exhaust and dehydration. The feeding device and the screw drive device adopt frequency conversion speed regulation to achieve synchronous speed regulation. 3. The extrusion die is part of the PVC that has been compacted, melted, and mixed and homogenized. Subsequent materials are pushed to the die by the screw. The extrusion die is a key component of pipe forming. 4. The vacuum-shaped water tank is used for the setting and cooling of pipes. The vacuum-shaped water tank is equipped with a vacuum system for setting and cooling and a water circulation system. The stainless steel box body circulates water spray for cooling, and the vacuum-shaped water tank is equipped with a front and rear moving device and a manual device for adjusting left, right and right. 5. The tractor is used to continuously and automatically draw the cooled and hardened pipe out of the nose for frequency conversion and speed regulation. 6. The cutting machine is automatically cut by the stroke switch according to the required length control, and the frame is turned over in time to implement assembly production. The cutting machine uses the fixed-length switch signal as the instruction to complete the whole cutting process. The cutting process is synchronized with the operation of the pipe during the cutting process. The cutting process is completed by electric and pneumatic drive. The cutting machine is equipped with a vacuum device to suck out and recycle the debris generated by the cutting in time. 7. The turning action of the turning frame is realized by the cylinder through the air path control. The turning frame has a limiting device. When the cutting saw cuts off the pipe, the pipe continues to be transported. After the delay, the cylinder enters the work to realize the turning action and achieve the purpose of unloading. After unloading, it is automatically reset after a delay of a few seconds and waits for the next cycle.
