摘要
分析了人造板释放甲醛的来源，述评了当前降低脲醛树脂甲醛释放量的措施，提出了多元改性工艺，采用该工艺生产脲醛树脂，甲醛释放量小，不需脱水操作．成本略有降低．
This paper analyses the sources of formaldehyde emission from wood-basedpanels,states the technological measures that are used at present to reduce the formaldehyde emission in the course of UF resin production,and puts forward a poly-modified technological process- With the process, the formaldehyde emission is small, the manipulationof dehydration is unnecessary and the production cost is reduced.
