The film bubbles of PE film blower have air holes, which may cause too much water content in the raw material particles. The reasons may also exist: too high extrusion temperature, too high fluidity of melt resin, too low viscosity, easy to fluctuate; adjusting extrusion temperature; too low extrusion temperature, too little amount of material; adjusting extrusion temperature. The air volume of the cooling air ring is unstable and the film bubbles are not uniformly cooled. Check the cooling air ring to ensure the uniform air supply around it.
It is disturbed and influenced by strong external air flow. Prevent and reduce the interference of external airflow. Power part energy-saving: Most of the energy-saving way is to save the residual energy of the motor, such as the actual power of the motor is 50Hz, and you actually only need 30Hz to produce, those excess energy consumption will be wasted, the frequency converter is to change the power output of the motor to achieve energy-saving effect.
The raw material particles (LDPE, HDPE, LLDPE, filler, etc.) are added into the feeding hopper and enter the screw from the hopper. When the raw material contacts with the screw oblique edge, the rotating oblique edge pushes the raw material particles forward. During the pushing process, the raw material is gradually melted through extrusion friction heating and external heating, and the melted material is extruded from the die mouth. The film barrel material is formed by blowing, cooling of air ring, pulling up of traction frame, traction roll and reeling frame.
