Correct copper plate cleaning method
Red copper is more widely used than pure iron. Every year, 50% of copper is electrolyzed and purified into pure copper, which is used in the electrical industry. The red copper mentioned here is really very pure, with copper content of 99. More than 95%. A very small amount of impurities, especially phosphorus, arsenic and aluminum, will greatly reduce the conductivity of copper. Oxygen in copper (it is easy to mix a small amount of oxygen in copper smelting) has a great impact on conductivity. Copper used in electrical industry must generally be oxygen free copper. In addition, impurities such as lead, antimony and bismuth will not combine the crystallization of copper, resulting in thermal embrittlement and affect the processing of pure copper. This pure copper with high purity is generally refined by electrolytic method: Impure Copper (i.e. crude copper) is used as anode, pure copper is used as cathode, and copper sulfate solution is used as electrolyte. When the current passes through, the Impure Copper on the anode gradually melts, and the pure copper gradually precipitates on the cathode. Copper thus refined; The purity can reach 99. 99%。
The copper plate is not limited by the processing temperature and remains brittle at low temperature. Hot melt welding such as oxygen blowing can be used at high melting point. The copper plate has good corrosion resistance and can ensure the waterproof effect of the tunnel in a long time. Chemical cleaning uses acid or acid salt with different strength to dissolve the scale. Whether it is simple acid dissolution or complex dissolution, it is an abnormal state in which the acid liquid is in direct contact with the equipment, which is the most undesirable situation causing equipment corrosion. In addition to the direct erosion of the cleaning liquid, For the need of descaling, increasing the temperature and speed of cleaning fluid will aggravate the corrosion. The corrosion damage of equipment in cleaning is shown as uniform corrosion in the cleaning process; Local corrosion in corrosion; Corrosion of blocked area caused by cleaning fluid entering deep hole or gap; The cleaning solution causes the de composition corrosion of the alloy; Intergranular corrosion caused by cleaning solution; Corrosion caused by metal hydrogen absorption during cleaning. Copper plate has excellent processing adaptability and strength. It is suitable for various processes and systems such as flat latch system, vertical edge bite system, BEM system, unit wall plate, rain drainage system, etc. It is applicable to various processing requirements such as arc bending, trapezoid and corner required by these systems. The stable protective layer makes the service life of copper plate more than 100 years.
The economic performance price ratio of copper bar is one of the best metal roofing materials. There are a variety of surface treatments to meet different building needs.

It is applicable to various processing requirements such as arc bending, trapezoid and corner required by these systems. There are a variety of surface treatments to meet different building needs. Copper oxide plate, which can form a uniform brown appearance. Copperplate is used for renovation of old buildings or new buildings with special requirements. The original copper plate has the characteristics of gradual change in metallic luster, making the building like having life. Tin copper plate can reach the effect of titanium zinc plate. The stable protective layer makes the service life of copper plate more than 100 years. The economic performance price ratio of copper plate is one of the best metal roofing materials.

It is the most reluctant situation to cause equipment corrosion.
