摘要
评述了超临界流体技术的原理、特点以及在表面精饰领域的应用和进展,重点介绍了超临界CO_2清洗硅晶圆,超临界萃取提纯电镀和化工中间体,超临界流体制备纳米微粒,超临界流体电沉积和化学沉积,超临界水氧化技术在处理各种难降解有机废水、工业污泥、废旧印刷电路板等方面的应用,以及超临界流体处理设备上的进展。事实说明,超临界流体技术在表面精饰行业有广阔的应用前景,是古老的表面精饰行业向技术更先进,工艺更环保,镀层质量更优异方向迈进的新途径。
The principles and characteristics of supercritical fluid technology and its application and progress in various aspects of surface finishing were reviewed. The emphasis is put on supercritical CO2 cleaning of silicon wafers, supercritical extraction and purification of intermediates for plating and chemical engineering, supercritical fluid preparation of nanoparticles, supercritical fluid electrodeposition and chemical deposition, and supercritical water oxidation in the treatment of various refractory organic wastewater, industrial sludge and waste printed circuit boards. The progress of supercritical fluid processing device was described. The facts show that supercritical fluid technology has broad application prospects in surface finishing. It is a new way to make the old-fashioned surface finishing industry more advanced in technology, more environmentally friendly in process and superior in the quality of coatings.
