摘要
在国内首次采用刮膜蒸发器对热固性酚醛树脂进行脱水。试验考察了分离过程真空度、进料速度、进料温度、刮膜蒸发器加热温度对分离效果的影响,探索了刮膜蒸发器应用于酚醛树脂脱水工艺条件,并成功应用于酚醛树脂工业生产。
Wiped film evaporator was used for the dehydration process of thermosetting PF resin production. Effect of vacuum degree,feed temperature,feed speed and heating temperature on the separation efficiency was investigated. This technique has been developed successly in the industrial process of phenolic resin production.
