Influence of temperature of hydrochloric acid solution on pickling
The Effect of Sodium Hydroxide Temperature on Acid Pickling
Acid pickling is a widely used method in industrial manufacturing processes. It involves the contact of a metal surface with a solution of acid, usually sulfuric acid, hydrogen chloride, or hydrochloric acid, for a period of time. This p......
Common problems and preventive measures in stainless steel surface treatment
Common Problems and Measures for the Acid Pickling and Passivation Treatment of Stainless Steel
Stainless steel is widely used in our daily life due to its excellent corrosion resistance and environmental adaptability. However, due to long-term use or use in some corrosive medium environments, it......
Ring-shaped watermarks occur on the edge of the electroplated plate hole
Galvanization is a process in which a layer of zinc is applied to the surface of zinc-bearing metals and alloys to improve their corrosion resistance. Its application is applied extensively to the marine, automotive, and architectural industries. One of its common applications is for zinc-plated p......
Reason Analysis of No Tin on Electroplated Nickel-Gold Plate
Nickel Plating GOLD Plate Does not Solder-Reason Analysis
Nickel plating gold plates are a demanding finishing procedure that requires precise material selection, correct surface preparation, and proper plating protocols. Gold plating has 3 main attributes: improves appearance, improves soldering......
