11. The membrane vesicle is unstable

Reason 1: the extrusion temperature is too high, the fluidity of the molten resin is too large, the viscosity is too small, and it is easy to fluctuate;

Reason 2: The extrusion temperature is too low, the discharge amount is less;

Reason 3: The air volume of the cooling air ring is unstable, and the cooling of the membrane bubble is not uniform;

Cause 4: The interference and influence of strong external air flow.

solution

① Adjust the extrusion temperature;

② Adjust the extrusion temperature;

③ Check the cooling air ring to ensure that the air supply volume around is uniform;

④ Prevent and reduce the interference of external air flow.
