urea resin adhesive

Factors affecting product quality of urea formaldehyde resin adhesive were analysed in details.

详细地分析了影响改性脲醛树脂胶粘剂产品质量的各种因素.

And it was discovered that the concentration of exonerative formaldehyde of the urea-formaldehyde resin synthesized reaches the F1 target of environmental protection, the initial adhesive force and gluing intensity is up to the national standard, but the cost of the resin is reduced obviously.

实验结果表明，合成脲醛树脂的甲醛释放量达到F1环保指标，初始黏结力、胶合强度等综合指标均符合国家标准，成本则有较大降低。

The experiments showed that the urea-resin adhesive produced a better effect;

试验表明：落叶松材的齿榫接合采用脲醛胶的效果较好；

The paper studied the preparation of modified urea-formaldehyde resin adhesive with polyvinyl alcohol ( PVA ) and melamine.
