客户说明：
1.我司磷化加工出来的产品可以大大提高盐雾时间，还可以为客户提供SGS检测报告
2.我们做磷化加工有将近20年的经验。
3.可以这么说吧，在长三角地区做的比我们好的没有，至少我们目前为止还没发现。
4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.无膜的原因：游离酸过低，促进剂含量太少，杂质累计过多，需要更换槽液了。
6.膜的形成速度过低：游离酸底，温度低，
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.有些人说我们高温锰系黑色磷化加工价格不便宜，但我想说一分钱一分货。
11.零件有些部分泛黄或生锈：温度需要加高，时间太短。
12.挂白灰是因为：磷化前零件就已经生锈，铁离子过多，沉渣太多，附在表面。
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
15.上海路丰助剂有限公司生产的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。
16.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。
1. We phosphating processing out products can greatly improve the salt fog time, can also provide for the customer SGS test report
2. We do phosphating process has nearly 20 years of experience.
3. So to speak, in the Yangtze river delta region to do more than our good no, at least we now haven't found.
4 high temperature manganese series black phosphating solution pretreatment including except oil, acid pickling process such as, say, if oil removing not thoroughly, can lead to a black phosphating film and surface has spots.
5. No film reason: free acid is too low, promoting agent content is too little, impurities accumulated overmuch, need to change the bath.
6. Film formation speed is too low: free acid base, low temperature,
7. Some say our high temperature nigrescence simple operation, it looks beautiful. But its energy consumption is large, inefficient, especially corrosion resistance is very poor, salt fog time can only for hours, at most, 10 hours.
8. Black and our black manganese series phosphate salt fog time is can't ratio, we can reach 72 hours,
9. Now some parts of the car it is strictly prohibited to use black technology, using manganese series phosphating, especially foreigners they generally require phosphating.
10. Some people said we high temperature manganese series black phosphating processing price is not cheap, but I want to say a penny a points cargo.
11. Parts some part of the yellowing or rust: temperature need heightening, time is too short.
12. Hang lime because: before the phosphide parts have rust, iron ion is overmuch, sediment too much, attached to the surface. 苏州黑色锰系磷化加工
13. Our customers all over the country's major cities, especially in jiangsu, and other industrial more developed place. 上海黑色锰系磷化加工
14. We can provide for the customer small kind try first 无锡黑色锰系磷化加工
15. Shanghai: Shanghai road feng auxiliaries co., LTD., production of high temperature manganese series black phosphating liquid stable quality, consumption is small, to make the product effect is good, has long been have won high appreciation among our customers.
16. Pretreatment is very key part, if pretreatment is bad to can has a great influence on phosphate. |
