摘要
采用卡尔费休水分测定仪和卡氏炉联用,测定PVC糊树脂中的水分含量。研究了检测时间、检测温度等测试条件。试验结果表明:该方法具有较高的准确度和精密度,相对标准偏差为4.45%,回收率为98%～105%。
By using combination technology of Karl Fischer titrimeter and boiler, the moisture content in paste PVC resins was measured. Some measurement conditions, such as time and temperature, were studied. The test results showed that this method had high accuracy and precision, and the recovery was 98%-105%.
