Product Introduction:
The special passivation agent for copper materials in the Pearl River Delta is a special protective agent for copper and copper alloys, which is a water-soluble process. It is a nanotechnology product. This protective agent forms a colorless and transparent film on the surface of copper and copper alloys, with a film thickness of several nanometers. It can prevent water, seawater, atmosphere, oxygen, hydrogen sulfide, sulfur dioxide, and some organic vapors from corroding the workpiece. Mainly used for the protection of copper and copper alloys in indoor environments.
Process features
:
. Water-soluble process, safe and environmentally friendly
. Simple process operation. Just immerse the thoroughly cleaned workpiece in the working fluid to form an effective protective film on the surface of the workpiece
3. This film hardly affects the welding performance and contact resistance of the copper layer, and is suitable for electronic components and Protection of the copper layer of the circuit board
. This protective layer has no protective effect against the corrosion of ammonia or cyanide
. The protective film can withstand baking at temperatures ℃-℃ for several hours without reducing the protective performance
.The treatment area is large, and it can treat at least - square meters per liter, and the actual maximum has reached 3 square meters/liter
.The acetic acid system has better stability and less corrosiveness than other systems containing formic acid.
.Environmental protection index of this product: complies with EU R environmental protection standards
Process flow:
The special passivation agent for Pearl River Delta copper materials is extremely easy to operate, just dilute the concentrated solution in pure water. use. The process is: copper plating, washing, washing and dipping in protective agent (pay attention to temperature and time, too short time will affect the protection effect, too long is okay), water washing (very important), water washing, spin drying (temperature should not be too high), inspection and storage
