当前,我国机械制造工业,步入一个新的历史时期。市场竞争加剧,优胜与劣汰机制作用越来越明显;高质优品充实发展,劣质粗造淘汰历史。 一叶知秋的金属表面涂装,在激烈的市场竞争中,机械产品行业一跃成为第一要素,市场的纽带,信誉的窗口。已是众目昭彰。然而涂装质量的保证体系在于涂装前磷化处理。工艺技术先进与落后,关系到涂装质量优劣。 1 工艺技术状况 At present, China’s machinery manufacturing industry has entered a new historical period. Market competition intensified, the winning and the mechanism of the phenomenon of becoming more and more obvious; full development of high quality and excellent products, inferior quality out of history. Autumn leaves of the metal surface coating, in the fierce market competition, the machinery industry has become the first element of the product, the market’s bond, the credibility of the window. It is obvious. However, the coating quality assurance system is phosphating before painting. Advanced technology and backward technology, coating quality advantages and disadvantages. 1 technology status
