摘要
提出了一种光伏用POE胶膜交联度的测试方法,即低温溶剂萃取法,萃取时间为7~10 h,萃取温度为40~80℃,烘干温度设置为140℃,真空度≥0.08 MPa,烘干时间为2~5 h。研究表明,采用该方法能快速且准确的测量出POE胶膜共聚物的含量,可为光伏行业中光伏组件封装用POE胶膜的交联度或交联水平的测试提供一种科学实用的测试方法。
A test of cross-linking degree of POE film is proposed by means of low temperature solvent extraction.The extraction time is 7~10 h and the extraction temperature is 40~80℃.The drying temperature is set at 140℃and the drying time is 2~5 h with the vacuum degree is more than 0.08 MPa.This method can quickly and accurately measure the content of the copolymer of POE film and the cross-linking degree,which provides a scientific and practical way to test cross-linking degree in PV industry.
