POM Z3510旭化成--POM has good conditi*** in terms of self-development technology level, stable operation time of 1000 ton units, and raw material sources. Some experts in the industry believe that domestic technology has the ability to build large-scale units in some key process links, but it needs a certain amount of capital investment to run the existing production units well, Improve various auxiliary processes to prepare conditi*** for the expansion of the plant scale.
The time of POM development in China is almost the same as that of DuPont company, which is earlier than Asahi Asahi and other companies in Japan. However, after ten years of development, there is a big gap between China and foreign companies in terms of technology level, such as ***all scale, high material c***umption and energy c***umption, low grade and brand, and unstable product quality. In the past, due to insufficient development of downstream products, ***all demand and planned economic system, POM in China missed the opportunity of industrialization of scientific research and development achievements. Up to now, POM is only operating in pilot scale plants, which is bound to be difficult to compete with foreign products. However, it should also be noted that among domestic engineering plastics
我国开始研制POM的时间与杜邦公司相差无几, 早于日本旭化成等公司, 但是经过儿十年的发展, 在技术水平上已与国外公司有了较大的差距, 表现为装置规模小、物耗能耗高、品级牌号少、产品质量不稳定。过去下游产品开发不够、需求量小、计划经济体制等多方面的原因使我国POM错过了科研开发成果产业化的时机, 到目前还只是在中试规模的装置中运行, 必然难以同国外产品竞争。不过还应该看到, 国内工程塑料中, POM在自行开发技术水平、千吨级装置稳定运行时间、原料来源等方面都是条件较好的, 业内一些***认为, 国内技术在一些关键工艺环节上已具备了建设大型装置的能力, 但需要一定的资金投人, 将现有生产装置运转好, 完善各种辅助工艺, 为装置规模的扩大化准备条件。
