钢铁磷化是防止钢铁生锈的化学方法之一 ,国内许多厂家生产的磷化液 (粉 ) ,都属于加温型 ,不仅耗能 ,而且工艺繁琐 ,处理时间长 ,成膜速度慢 ,磷化膜难以达到均匀、细致的效果。并且溶液沉渣较多 ,使用寿命短。我厂通过长时间的试验 ,采用常温低锌快速磷化粉 ,该工艺浸渍、喷 Iron and steel phosphating is one of the chemical methods to prevent steel from rusting. Many phosphating liquids (powders) produced by many domestic manufacturers belong to the heating type, which not only consumes energy, but also has complicated process, long processing time, slow film forming rate, Difficult to achieve a uniform film, meticulous results. And more sediment solution, short service life. I plant through a long period of experimentation, the use of low temperature zinc rapid phosphating powder, the process of impregnation, spray
