摘要
本文真对脲醛树脂合成与生产中存在的几个问题,从理论和实践上进行了讨论。这些问题包树脂合成中的化学反应,树脂溶液的稳定性,树脂龟裂性的抑制和游离甲醛含量的控制。
Some problems cxisted in the synthesis and producttion of urea-formaldehyde resin was discussed on theory and practice.The factors to effect the chemical reactions,stability of resin solution,cracking resistance and the free-formal content were in-cluded.
