磷化处理是目前作为底材涂装工艺使用最广泛的一种前处理工艺。国外先进国家,无论从工艺设计或溶液配制上都领先于我国,我国过去在这方面没有引起重视,近年来虽有些重视,但仍不普及,且工艺和设备仍很落后,故仍有必要在这方而做些研制工作,以便满足国内日益发展的需要。 Phosphating is currently the most widely used as a substrate coating process pre-treatment process. Foreign advanced countries, both in terms of process design and solution preparation, have not drawn much attention in this respect in our country. Although some attention has been paid in recent years, they are still not widely used and the technology and equipment are still lagging behind. Therefore, it is still necessary This side and do some research and development work in order to meet the growing domestic needs.
