PP pipe extrusion production line is a one-time extrusion molding of special PP raw materials through a plastic extruder, which is applied to industrial ventilation ducts and special ventilation ducts for environmental protection equipment, especially for acid and alkali resistant, corrosion resistant and anti-aging plastic pipeline projects. Due to the use of hot melt and electric melting connections in PP pipes, the integration of the interface and the pipe material is achieved, and it can effectively resist the circumferential stress and axial impact stress generated by pressure. Moreover, PP pipes do not add heavy metal salt stabilizers.
1. The PP pipe production line uses a dedicated high-efficiency extruder for PP pipes. The screw adopts a barrier and mixing head structure, and the barrel adopts a new type of slotted barrel. The plasticizing and mixing effects are good, and the extrusion volume is large and very stable. The spiral die head designed for PP large-diameter pipes has the characteristics of low melt temperature, good mixing performance, low mold cavity pressure, and stable production
2. The entire production line adopts proprietary technology for sizing and cooling systems, using water film lubrication and water ring cooling to meet the requirements of PP materials and ensure stable diameter and roundness of high-speed production pipes
3. Adopting a specially designed multi-stage vacuum sizing box to control the vacuum degree, ensuring the dimensional stability and roundness of PP pipes The extruder and tractor are controlled by imported speed controllers, which have good stability, high precision, and high reliability
4. PLC is used for programmed control, with a well-designed human-machine interface. All process parameters can be set and displayed through the touch screen.
