PEI high temperature film casting film extruder
Overview
Product Features
(1) Screw and barrel adopt advanced design;
(2) The drive motor realizes stepless speed regulation by frequency converter. The drive motor realizes direct-connected transmission, which can ensure the smooth and safe operation of the equipment.
(3) The temperature control system of the instrument is heated by ceramic heater, which has fast temperature rise and long service life. The cooling system is cooled by fan, without temperature impact.
(4) The instrument control system adopts the programmable computer controller system originally produced in Europe, and the control temperature adopts PID plus fuzzy control algorithm, so the temperature control is accurate. Each drive motor of the whole machine can be controlled locally or online, which is easy to operate, easy to understand and beautiful interface. The setting, modification or display of all operating parameters can be operated through the 10-inch true-color touch screen, with multiple interlocking protection and alarm functions.
PEI refers to polyetherimide, a thermoplastic engineering resin with an amber transparent solid appearance, which has excellent mechanical properties, electrical insulation, radiation resistance, high and low temperature resistance and wear resistance. PEI also has good flame retardancy, chemical resistance and electrical insulation properties. The glass transition temperature is very high, up to 215 ℃. PEI also has very low shrinkage and good mechanical properties in the same direction.
Application
1. Communication field
PEI material is used as optical fiber connector for optical communication, optical components of optical transceiver module, radio frequency connector insulator, base station cavity filter plastic cavity, filter tuning screw, antenna internal fixing screw, ring phase shifter bracket, etc. In addition, foamed PEI material also has advantages in millimeter wave antenna cover.
2. Aerospace
PEI can be used in aerospace, such as air valve and fuel valve, food tray container, steering wheel, internal cladding and various structural components; PEI one-way belt can be used for seat frame and trunk, etc.
3. Automobile
PEI can be used for control valve, oil pump, lamp, laser radar, fender and other parts of automobile, and PEI film can be used as high-temperature dielectric film of capacitor
