大容量差别化聚酯工程技术探讨(一)

A Study on Large-capacity Differential PET Engineering Technology (Ⅰ)

本文介绍了国内外主要聚酯工程技术的发展,详细探讨了大容量差别化聚酯工程国产化的工艺理论、自控技术和机械技术研究,在此基础上简要分析了国内大容量差别化聚酯工程技术的开发难点和发展方向。认为大容量差别化聚酯工程技术已实现国产化,其关键点为共缩聚组分的加入研究。

Development of some main PET engineering technologies at home and abroad were introduced in this article. Based on studying the process theory, auto-control technology and machinery, the author analyzed the difficulty and trend of developing large-capacity differential PET engineering technology in China and pointed out that adding copolymer to the process is the key point.
