我国目前规模最大、技术最先进的聚甲醛工程日前在位于云南省水富县的云天化集团公司开工建设。新建的云天化聚甲醛工程年产聚甲醛能力达1万吨,工程投资4亿元,预计工期为1年。其工程的建成,将极大地改善云南省化工产品结构,缓解我国目前聚甲醛生产供不应求的现状,对推动地方经济的发展有着重要意义。据悉,聚甲醛属高附加值的精细化工产品,广泛适用于金属替代品,在汽车、电子、卫星等多种领域有着广阔的市场前景。由于其科技难度大、工艺复杂,60年代到70年代我国试图引进均未成功。而80年代至今引进的三套装置又存在规模小、技 China’s largest and most technologically advanced polyformaldehyde project has recently started construction at Yuntianhua Group, located in Shuifu County, Yunnan Province. The newly-built Yuntianhua polyformaldehyde project has an annual capacity of 10,000 tons of polyformaldehyde and a project investment of 400 million yuan. The project is expected to have a construction period of one year. The completion of the project will greatly improve the structure of chemical products in Yunnan Province, ease the current situation in which polyoxymethylene production in China is in short supply, and is of great significance to the promotion of local economic development. It is reported that polyoxymethylene is a high value-added fine chemical product that is widely applicable to metal substitutes and has a broad market prospect in various fields such as automobiles, electronics, and satellites. Due to its great difficulty in science and technology and complicated technology, China’s attempts to introduce them from the 1960s to the 1970s were unsuccessful. The three sets of devices introduced since the 1980s are small and technical.
