四、工艺说明
使用时将本品与水按1:10(容积比)加水稀释为工作液,搅拌均匀后升温至92-99°C即可使用,磷化时间15分钟。新配工作液要经过试磷化合格后方可批量生产。
1.测试:取工作液5毫升于250毫升三角瓶中,加蒸馏水50毫升,滴2滴甲基橙指示剂,用0.1N氢氧化钠标准溶液滴定至橙黄色即为终点,此时所消耗的0.1N氢氧化钠毫升数乘2为Fa;然后再滴4~5滴酚酞指示剂,继续用0.1N氢氧化钠标准溶液滴定至出现红色即为终点,此时所消耗的0.1N氢氧化钠总毫升数乘2为Ta。
2.最佳工作状态:Fa:6~9,Ta:55~80,酸比(Ta/Fa):6~9。
使用温度:92°C以上,处理时间:15~20分钟。
3.调整:当Fa<6或Ta<55时,应补加浓缩液;当Ta>80时补加水;当Fa>9时,补加碳酸钠,每升工作液加0.5克碳酸钠,Fa降低1个点。
4.注意补充槽内挥发掉的水份;定期清理槽内底部的沉积物。

六、包装、储存
30kg/桶塑料桶包装。本品应储存于阴暗处,防止日晒、高温,长期保存不变质。
客户说明:
1.我司生产的防锈油可以大大提高盐雾时间,还可以为客户提供SGS检测报告
2.上海路丰助剂有限公司生产的嘉兴高温锰系黑色磷化液质量稳定,消耗量小,做出来的产品效果好,长期以来一直得到客户的好评。
3.前处理是非常关键的一部,如果前处理不好会对磷化有很大影响。
4.宁波高温锰系黑色磷化液前处理主要包括除油,酸洗等工序,比方说如果除油不彻底,可能导致的是黑色磷化膜便面有花斑。
5.着色前必须水洗,而且需要注意的是着色剂千万不能加热,很有可能导致着色剂不稳定,甚至出现报废的可能。
6.着色剂时间也不要太长,看见有一层黑膜就可以了,否者可能会导致黑磷化掉膜。
7.有人说我们的高温发黑操作简单,看起来美观。但是它能耗大,效率低下,特别是耐腐蚀性很差,盐雾时间只能达几个小时,最多就十几个小时。
8.发黑和我们的黑色锰系磷化盐雾时间是没法比的,我们可以达到72小时,
9.现在一些汽车零部件严禁使用发黑工艺,采用锰系磷化,特别是老外他们一般都要求磷化处理。
10.有些人说我们嘉兴高温锰系黑色磷化液价格不便宜,但我想说一分钱一分货。
11.我们的磷化液配水后要加碳酸钠中和一部分磷酸盐。这是因为我们的黑色磷化液浓度高,以后消耗量也低。
12.一般老客户只要用了我们的产品就不会换了。宁波高温锰系黑色磷化液他们知道我们,信任我们。
13.我们的客户遍及全国各大城市,特别是江浙沪等工业较为发达的地方。
14.我们可以为客户提供小样先试
