Message: | PE, PP, PS, PVC board production line
PE, PP, PS, PVC board production line can be used to continuous produce PP, PE, ABS, PMMA, PC, PS, PVC single layer and multilayer sheets. Sheet width at 2000mm and below, the thickness of 0.15-3mm. Extruder according to different materials, select (non-degassing, venting type) single screw extruder, screw adopting special mixing function and precise temperature control system ensures the high plasticizing, high capacity and stable plastic extrusion. Temperature control is within 1, which can control plasticization process and sheet thickness flatness in accuracy. Screen changer and die fast screen changing device ensures no leakage, fast and effective screen changing. mould choosing different structure form according to different material, coat hanger die adopt page double throttle design, easy to adjust the flow distribution, the adjustment of sheet thickness is more accurate. Three roller calender according to the sheet thickness, 45 tilt type three roller or vertical three roller or horizontal three roll calendar can be adopted, special design of independent control for three roller temperature, free adjustment for roller gap, angle adjustment for middle roller, ensure the calendering effect and thickness uniformity.
Sheet thickness control uses screw adjustment and pressing wheel two-way adjustment, which can accurately control sheet thickness. Independent control of roller temperature control system can precisely control the temperature of the roller to ensure sheet thickness uniformity. |
