聚酰亚胺薄膜流涎成型技术研究
|
摘要
通过分析聚酰亚胺薄膜现有制造技术及存在的问题,对薄膜流涎成型工艺进行改进,在现有成型工艺流程基础上增加正负风压处理、静电处理、模头角度调节处理等措施,并通过引入相应的装置制得高性能聚酰亚胺薄膜。结果表明:采用改进流涎成型工艺制得的薄膜透光率提高、摩擦系数降低、拉伸强度提高、伸长率增加,同时厚度均匀性、膜卷平整性、外观质量均得到了改善。
The extrusion casting molding technology of films was improved by analyzing the manufacturing technology and existing problems of polyimide film. The positive and negative air pressure treatment,electrostatic treatment, die angle adjustment treatment were added to the existing molding process, and then corresponding devices were introduced to prepare high performance polyimide films. The results show that the films prepared by the modified extrusion casting molding process have higher transmittance, lower friction coefficient, higher tensile strength, and larger elongation, and the thickness uniformity, roller smoothness, and appearance are improved.
