摘要
介绍了一种快速测定铸造用自硬呋喃树脂含氮量的方法,其特征是采用多段升温的方式消化试样和用定氮仪对样品进行蒸馏,该方法操作简便,测试效率高。
A quick determination method of nitrogen in no-bake furan resin for foundry was introduced. As characteristic of the method, digestion device digest sample by multi-stage heating, then the sample was steamed by kjeldahl apparatus. This method is handy to operate and efficient of process.
