Electrical control part, the general unit is equipped with unit operating cabinet, the general power supply is pushed by the main button, the main switch of the motor is turned on, the fuselage and tee can be controlled separately by the button switch, and the electric heating of each button of the die can be controlled. The key part of the two groups of coils is thermocouple automatic temperature measurement and automatic temperature control. In normal production process, the temperature can be automatically controlled to ensure that. The production process is stable and reliable. Take Guoyan Brand PP film blower as an example: the barrel and screw of extruder are made of high quality alloy steel, which has good hardness and corrosion resistance after nitriding and precision processing. Blown film method: using the down water cooling method to make the film achieve high transparency.
The coiling device of PE film blower adopts pressure friction coiling or central coiling, and adopts torque motor adjustment. The coiling is flat and easy to change. The melt index (MI) of resin particles can not be too large, and the melt index (MI) is too large, so the viscosity of the melt resin is too small, the processing range is too narrow, the processing conditions are difficult to control, the film forming ability of the resin is poor, and it is not easy to process the film. In addition, the melt index (MI) is too large, the relative molecular weight distribution of the polymer is too narrow, and the strength of the film is poor.
