通过分析气泡、杂质、色差等因素对聚酰亚胺薄膜表观质量的影响，从树脂合成和流涎液膜两过程对气泡去除工艺进行研究，对现有消泡釜及消泡工艺、流涎液膜处理装置及流涎工艺进行改进。结果表明：通过新型消泡釜和新型PAA液膜消泡装置均能有效的消除聚酰亚胺薄膜表面的微小气泡，使聚酰亚胺薄膜产品的色差减小，厚度公差降低，外观质量大幅提高。

Through analyzing the effect of bubble, impurity, and colour difference on the surface quality of polyimide film, we studied the bubble removal technology from resin synthesis and film casting process, and the existing defoaming kettle and defoaming process, casting equipment and casting process were improved. The results show that the micro-bubbles on the polyimide film surface could be removed by the new defoaming kettle and new PAA liquid film, the product’s colour difference and thickness tolerance decrease, and the appearance quality is improved significantly.
