Wx - 988-5 phosphating process note:
1. According to the new match phosphating "matching, a liter of working fluid and sodium carbonate (namely soda) add 10 grams, the black and 12 grams
2. Phosphating solution, direct heating can, phosphating liquid temperature must control at degrees or boil.
3. The workpiece in need of phosphide jitter, basic every minutes every time you move
4. Table adjustment kind of fluid temperature control in table adjustment after needs to be washed directly phosphating can, kind of liquid dont need dilution direct heating.
5. Twice phosphating first 5 minutes, 15 minutes for the second time
6. Phosphating cant use iron groove, stainless steel tank best
7. Before phosphide oil removing rust removal must be clean.
Surface black, surface phosphating, surface ni-p plating have why to distinguish?
Steel work surface black finish, there are also called blue.
Black finish now commonly used methods of the traditional basic heating black and appear later cold black two.
But cold black process for low carbon steel effect is not so good.
A3 steel with alkaline black is better.
Alkaline black segmentation out, and have a dark and two black difference.
Hair black liquor consists mainly of sodium hydroxide and sodium nitrite.
When the temperature of black for large tolerance, probably in 135 degrees to 155 degrees Celsius can get good surface, just the time
Just some length.
In practical operation, the need to pay attention to is black workpiece before rust removal and the oil quality, and after black passivation oiled. Black the stand or fall of quality often
For these process and change.
Metal "blue" liquid medicine
Using alkaline oxidation method or acid oxidation method; The metal surface to form a layer of oxide film, in order to prevent the metal surface is corrosion, this process is called"
Black coating ".上海磷化液
Black metal surface is "blue" after processing by the formation of the oxide film, its outer mainly ferroferric oxide, inner lining for ferrous oxide. 上海防锈油
A, alkaline oxidation method "blue" liquid medicine苏州磷化液
(1) the metal surface must be clean and dry after, to carry out "hair basket" treatment. 常州磷化液
(2) metal device for "blue" processing conditions and metal of carbon content related, "blue" solution temperature and metal components in one of the place无锡磷化液
Richard time under reference table. 镇江磷化液
(3) every week or so on schedule analysis solution of sodium nitrate, sodium nitrite and sodium hydroxide content, in order to timely supplement relevant component. a上海磷化加工
After half a year, use should be replace all solution. 上海达克罗加工
(4) metal "blue" treatment, had better use hot suds rinse several minutes, then rinse with cold water. And then, and hot water washing, blow in.宁波磷化液
