The use of blown film machines and lab extruders:
1. Check that the temperature automatic control is intact, the heating apparatus is intact, pay attention to adjusting the heating temperature in time within the target range;
2. Check the traction speed, control the thickness of the film, observe and adjust the thickness of the film uniformly, and the diameter of the film meets the standard.
3. check air storage cylinder pressure should not be too high, but there should be standby pressure.
4. Check and control the proportion of raw materials and mix evenly; Check the impurities in raw materials, especially the timely use of magnets to check the iron mixing.
5. check the reduction gearbox location and the lubrication condition of the air compressor cylinder lubricants.
6. check the temperature rise and mechanical transmission of each motor regularly.
