הסיבה ושיטת הטיפול של הסרט המיוצר על ידי מכונת ניפוח הסרט דביקים מדי והפתיחה גרועה

Jan 15, 2022השאר הודעה

סיבת הבעיה:

① The type of resin raw material required for the production of the film blowing machine is wrong, and it is not a film-blown low-density polyethylene resin particle, which does not contain an opening agent or the content of the opening agent is low;

②The temperature of the molten resin is too high and the fluidity is too large;

③ The inflation ratio is too large, resulting in poor opening of the film;

④ The cooling speed is too slow, the film cooling is insufficient, and mutual bonding occurs under the action of the traction roller pressure;

⑤ The traction speed is too fast.
