Product Details

BY-82 Acid Copper Cleaner

1 Introduction:

Our company's "tri-acid" pickling acid fog for raw copper is environmentally friendly and safe. It has developed BY-82 solid acid cleaning agent based on years of work experience. Suitable for cleaning copper and its alloys.

2. Main features:

2.1 Low acidity, no acid mist, solid packaging, convenient and safe transportation.

2.2 The use of the cleaning agent has low cost, good effect, fast degreasing speed and long service life.

2.3 Preparation does not choose water quality, low foam, non-combustible, non-explosive, safe to use.

2.4 The over-corrosion is small, the workpiece loses little weight, and there is no hydrogen embrittlement.

2.5 No nitrate, no phosphorus, nitrogen, in line with EU ROHS directive, environmental protection treatment pressure is small.

2.6 Different processing methods, the surface gloss after cleaning is different.

3. Scope of application:

Suitable for impregnation of copper and its alloys

5. Note:

5.1 Initial preparation of 1m3:

Add BY-82 type degreasing 50-100kg to the tank, add water to 1m3, stir evenly, and heat to the working temperature. .

5.2 Adjust 1m3:

With the continuous operation of the bath, its cleaning and decontaminating ability is gradually reduced, and BY-82 should be properly supplemented regularly. After the working fluid has been adjusted several times, the degreasing effect of adding BY-82 working fluid is still not obvious, then the new fluid should be replaced.

5.3 Preparation of ultrasonic cleaning, the effect will be better for complex long and short workpieces.

5.4 Before the degreased workpiece is transferred to the next process, it should be cleaned in flowing clean water.

5.5 Pay attention to salvage the oil and dirt on the liquid surface to prevent the workpiece from being contaminated again.

5.6 Heavy oil stains use compressed air to stir or make the workpiece move relative to each other in the bath, which is beneficial to accelerate the removal of oil stains.

5.7 Take 10 ml of working solution, titrate with 0.1N sodium hydroxide, bromophenol blue as indicator, the number of milliliters of sodium hydroxide solution consumed and the number of free acidity.

6. Packaging and storage:

25kg lining plastic bag, stored in a cool dry place to prevent moisture.

7. Environmental treatment:

The product is mainly composed of non-ionic surfactant and builder. The PH value is acidic. When it is discharged, it needs to be neutralized by alkali and then separated by oil and water.
