| 摘 要： | 通过一种脲醛树脂水解稳定性检测方法的建立,模拟在热压条件下,脲醛树脂在不同反应条件下水解稳定性的变化。实验表明,相同的pH值下,树脂水解稳定性随树脂含水率的提高而下降;相同含水率下,树脂水解稳定性随PH值下降而下降。

| Abstract: | A method for testing the hydrolysis of urea-formaldehyde resin is established to simulate hydrolysis of cured Urea-formaldehyde resin under heating press conditions of making PB or MDF.The change of hydrolytic stability of cured Urea-formaldehyde resin is studied.The results show lower PH or higher moisture of resin results in lower hydrolytic stability. |
