The cleaning method of red copper bar is introduced

Copper row is pure copper of high purity and is usually refined by electrolysis: impure copper (i.e. coarse copper) is used as the anode, pure copper as the cathode, and copper sulfate solution as the electrolyte. When the current passes through, the impurity copper on the anode gradually melts, and the pure copper gradually precipitates on the cathode. The resulting copper is purified to 99.99% purity. Copper bar is not affected by the processing temperature of copper bar, and it is not brittle at low temperature, and the high melting point can be hot melt welding such as oxygen blowing. Copper bar has good corrosion resistance, which can ensure the waterproof effect of the tunnel for a long time. Chemical cleaning is done using acids or salts of varying strength. No matter it is simple acid dissolution or complex dissolution, it is an abnormal state of direct contact between acidic liquid and equipment. In addition to directly etching the cleaning fluid, it is necessary to remove dirt, increase the temperature of the cleaning fluid, and increase the speed of the cleaning fluid, which increases corrosion. The corrosion damage of copper bar in cleaning process is uniform corrosion. Corrosion in local corrosion; Clean liquid into the deep hole or gap caused by the blocked area; The cleaning liquid makes the alloy separate and corrode; Cleaning fluids can cause crystal corrosion. Corrosion caused by absorption of metal  during cleaning.

Machining adaptability and strength, suitable for a variety of processes and systems, such as flat locking systems, vertical block systems, bem systems, unit wall panels, storm water drainage systems. Suitable for the various machining requirements required by these systems, such as arc, trapezoid and turn. The stable protective layer can make the life of copper bar more than 100 years. The economic performance and price ratio of copper bar is one of the best copper bar in metal roofing materials. A variety of finishes are available to meet different architectural needs. Copper bar has excellent production and processing adaptability and compressive strength, and is suitable for a variety of processing technology and system software, such as flat lock system software, vertical blocking system software, Bem system software, modular wall, precipitation discharge system, etc. The application of this system software to the various manufacturing requirements, such as arc, ladder and bend. There are a variety of metal finishes to consider for different engineering and construction requirements. Oxidized copper bars produce a well-proportioned dark brown appearance. Patina is used for the renovation of the old building or the new building. The metal texture of the initial copper row is slowly changed to make the building more beautiful. Tin - copper row can exceed the actual effect of titanium - zinc plate.
