低聚合度多聚甲醛制造工艺

Manufacturing Technology of Lower Polyformaldehyde

用生产方法与聚合度指标相结合的方法，将低聚合度多聚甲醛和固体甲醛作出明确区分。较为详细地论述了低聚合度多聚甲醛制造过程的反应原理和工艺原理；介绍了低聚合度多聚甲醛的一般生产方法；对不同的生产方法进行了分析比较，并对该产品国内外技术现状及国内未来技术的发展趋势作出判断。

In this paper,lower polyformaldehyde and solid formaldehyde is distinguished by combining the productive method with the quality indexes of polymeric degree clearly.It discussed reactive and technological principle in the productive process of the lower polyformaldehyde,introduced its productive general method,compared the various productive methods,sized up the situation of the technological development of this product at home and abroad,and judged progressive tendency of this technology at home.
