| 摘 要： | 通过一种新的已固化脲醛树脂水解稳定性评估方法的建立,研究了在较高温度下,湿度、pH值与已固化脲醛树脂水解稳定性之间的关系。揭示了湿度、pH值对固化的脲醛树脂水解稳定性有较大的影响。同时通过不同评估方法的对比,也验证了新的评估方法的可靠性。

| Abstract: | A new test method for evaluating the hydrolytic stability of UF resin is developed and is used to study the relation between humidity/pH and the hydrolytic stability of UF resin.Results reveal that the hydrolytic stability is greatly influenced by humidity and pH of UF resins.Meanwhile,the new method is proved to be reliable by comparing it with other evaluating methods. |
