Degreasing line
1.description for the degreasing and rinsing line:
When the strip runs through alkali liquid tank, and the strip is set as anode or cathode through DC with reversal polarity, then gas created on surface of the strip, which emulsifies the oil film and separate the oil from the strip surface. It is proved by productive practice that the processing of electrolytic degrease is better than alkali degrease in many sides, such as degreasing efficiency and quality.
2.The technical Parameter of degreasing and rinsing line
