Product Description

Alloy electrolysis degreasing powder

BC-18 alloy electrolytic oil powder

Product Code No. 11018

Description :

BC-18 is a white solid fine-grained powder, phosphate-free, alkaline and water-soluble anode electrolytic degreasing agent, suitable for die-casting zinc alloy, copper, brass, bronze, (forging or casting) and other copper alloys.

The advantages:

1 . The phosphate-free degreasing agent, not cause effluents quality oxide.  

2 . The surfactant contained is easily decomposed by organisms.  

3 . Excellent effect at low temperature operation, 43-54 ℃  

4 . Very high tolerance to hard water.  

5 . It is easy to wash, and the amount of foaming is small, so that the substrate will not appear cloudy.  

6 . The current density tolerance is large, and the operation and management are easy.  

7 . Generally used for secondary degreasing electrolysis  

8 . Generally applicable to various metal substrates that do not contain ferrous metals.  

BC-18 is mainly used for electrolytic degreasing without ferrous metals. It will not cause low pH , corrosion of die-cast zinc alloys, or scorching of brass and copper alloys in high current density areas.

If it is necessary to extend the electrolysis time during operation, please note that the operating temperature must be kept in a lower temperature range.

Operating conditions : 


45-75 g/L


43-54 ℃


15-120 seconds




Stainless steel tank, titanium tube exchanger (or heater)             

 Current density

Die-cast zinc alloy 1-3 amps /dm 2  


Yellow cast copper 2-4 AMPS / DM 2                

If the electrolytic degreasing substrate is a die-cast zinc alloy, the operating temperature must be maintained at 43-48 ℃


Bath method :

1 . Drain the waste liquid and clean the sink  

2 . Add soft water to 3/4 water level  

3 . Heat to 65 ℃, easy to dissolve  

4 . Slowly add BC-18 and stir to dissolve  

5 . After the medicine is dissolved, fill the water level  

6 . Can be used after cooling down to 45 ℃  


Typical operation process of electrolytic degreasing (zinc alloy, brass, copper)

1 . One heating degreasing, BC-16 dewaxing powder

2 . Washing or immersion in low concentration BC-16 60-65 ℃

3 . Spray degreasing

4 . Water wash

5 . Reheat degreasing, BC-17 alloy degreasing powder .

6 . Washing with water or low concentration of the BC-18 alloy powder electrolytic degreasing puddle

7 . Anodic electrolytic degreasing, the BC-18 is an alloy powder electrolytic degreasing 45-60 G / L, 43-54 deg.] C ,. 6 volts Laid

8 . Water wash

9 . Acid activation

10 . Water wash  

11 . Water wash  

12 . Base copper  


Analysis method :

1. Take 10 ml sample from the tank in a 250 ml Erlenmeyer flask, and then dilute it with 50 ml pure water.

2. Add 3-5 drops of phenolphthalein indicator

3. Titrate with 0.5N HCl solution until the light red disappears as the end point.

4. Record the titration ml Number

5. Calculation:

   mL 0.5N HCl × 3.97 = g/L BC-18 alloy electrolytic oil powder


Problem countermeasures :

1 . It is very important to determine the working electrode (positive and negative electrode). The wrong electrode selection will cause technical problems.  

2 . There are several factors that cause scorching:  

  a. The temperature or concentration is too low             

b. The voltage is too high             

c. Current density is too high             

d. Metal substrate is not suitable for electrolytic degreasing             

3 . When adjusting the current density, if the current density is found to be too low, the electrode may be polarized, so the cathode plate and electrode lead must be cleaned regularly.  

Matters needing attention :

BC-18 alloy electrolytic oil powder is a kind of dry alkaline substance, which must be separated from acidic substances during storage. Please wear goggles or protective clothing when adding medicine. If it comes in contact with the skin, rinse immediately with plenty of water and send it to a doctor for treatment immediately.


Wastewater treatment :

BC-18 alloy electrolytic oil powder is alkaline, does not contain phosphate, and is easily biodegraded. The waste liquid can be discharged when the pH value is 6-8 after neutralization with acid .
