四、用法
1．使用时将A剂：B剂：水按1：2：6（容积比）稀释成工作液，搅拌均匀，即可。常温使用，处理时间：1～5分钟。
2．将经过前处理的工件浸入本溶液中1~5分钟，即可在工件表面生成一层黝黑一致的膜层，经过水漂洗后进入下道工序。着色时间的长短客户可根据自己的实际要求延长或缩短，时间短颜色浅，时间长颜色深，适当掌握可降低成本。

WX - 1068 type steel black phosphating stain
Application: used in iron and steel parts before phosphide black coloring process, to make the work get excellent decorative.
Second, the characteristics
This product (solution) is weak acid. Normal use, coloring not choose the rigid, do not produce from heat, no volatile produce; Additional adjustment, no emissions, cycle use; Coloring colour and lustre after dark consistent, and has good corrosion resistance, the anticorrosion ability after phosphide will be further improved.

Colorless transparent liquid Four, usage 黑色着色剂
1. When using will be A agent: B agent: water according to the (volume ratio) dilution into working liquid, stir well, then. Normal use, the processing time: minutes. 上海磷化液
2. Will pass the pretreatment of workpiece dip this solution minutes, can in the workpiece无锡磷化液surface generating a layer of dark consistent membrane layer, after water rinse to enter the next process. Coloring time length customers can acc苏州磷化液ording to their actual requirements extend or shorten, short time color shallow, long time color deep, appropriate control can reduce cost. 常州磷化液
Five, the technological process 镇江磷化液

Six, adjust 上海达克罗加工
1. Test: take 1 ml of working liquid in ml of triangle flask, and distilled water ml, drop drops of methyl orange indicator, with N sodium hydroxide standard solution titration to orange as an end, at this time the consumed N sodium hydroxide ml number for Z1; And then drop four ? 5 drops phenolphthalein indicator, continue to use 0.1 N sodium hydroxide standard solution titration to appear red as an end, at this time the consumed 0.1 N sodium hydroxide total ml number for Z2.
2. Of the best work state:
3. When the pH value is minutes with black or not is A red and black, please timely added A agent (reduce Z1), additional quantity V3 = measured ). (V working liquid for the total volume number, similarly hereinafter)
4. When pH value rise to, coloring speed slow down, in minutes of a blue black, serious when red, please timely additional B agent (rise Z2), additional quantity V1 V2 measured).
Seven, other instructions
1. No special circumstances please don't emissions, circulating operation, otherwise, it will increase the cost.
2. The workpiec in the loading basket must avoid overlapping, in overlapping surface additive gauze off or design special hanging fixture. Coloring process best interval 5 minutes poppet once, but don't jitter impact to avoid coloring film scratches.
Eight, packing, storage
Packed, A agent: kg/barrel Agent kg/barrel.
This product should be stored in shady and cool place, prevent high temperature, sunlight, long-term preservation won't metamorphism.
