PLA/PBAT Degradable Plastic Double Column Hydraulic Screen Changer
PLA double-column hydraulic screen changer is used for chemical fiber, blown film, flat film, cast film production, pipe, sheet, wire, fiber manufacturing, pelletizing line, recycling, etc. It can meet the production of high temperature, high pressure and high extrusion of any polymer material. It can be used in conjunction with extruders of different standards. It does not stop to change the screen, the product is not interrupted, and the material is not leaked.
The double-column body and plunger of the screen changer for PBAT degradable materials are made of high-quality alloy steel, which has undergone heat treatment and nitriding treatment. After nitriding treatment of the flow channel, it is mirror-polished, indicating that the roughness Ra is less than or equal to 0.4μm, and the polishing requires the use of 800 mesh. The above abrasives are polished to mirror grade or above, with high finish and wear resistance.
The screen changer for PLA degradable materials needs to strictly control the gap between the main body and the plunger, and can achieve excellent sealing and durability through rigid material surface-to-surface sealing; It can achieve a large filtering area and have higher pressure resistance; in normal production, dual-channel filtering at the same time. When replacing the filter screen, a plunger is pushed out of the main body, and then the filter screen is replaced. Alternate replacement is carried out to solve the production interruption or hollow particles caused by the introduction of air during the screen change.
The PLA hydraulic screen changer is equipped with an operating handle to complete the screen change. The operator operates the control handle of the hydraulic station to perform basic operations on the upper and lower plungers of the screen changer alternately: push out the plunger - clean the silo - replace the filter screen - pull the plunger To the position of feeding and exhausting -- after the exhaust is completed, the main body of the screen changer is completely pulled into the working position; the electric control cabinet instrument transmits the temperature and pressure signals of the screen changer to the central control center to ensure the stable production.
