Introduction and use of cathode copper
The blister copper (containing 99% copper) is pre-made into a thick plate as the anode, the pure copper is made into a thin sheet as the cathode, and the mixed solution of sulfuric acid (H2SO4) and copper sulfate (CuSO4) is used as the electrolyte. After electrification, copper dissolves from the anode The copper ions (Cu) move to the cathode, and after reaching the cathode, electrons are obtained and pure copper is precipitated at the cathode, which isCathode copper, also known as electrolytic copper.
Cathode copperthe use of:
Copper is one of the oldest metals used by human beings. Archaeology proves that as early as 10,000 years ago, the West Asians had used copper to make ornaments and other objects. Archaeology also found that as early as about 3000 BC, copper and tin The bronze alloy made of copper has brought mankind into the Bronze Age. Copper is malleable, corrosion-resistant, tough, and is an excellent conductor of electricity and heat; alloys formed of copper and other metals such as zinc, aluminum, tin, nickel, etc., have New features with many special uses.
Today copper has been widely used in household, industrial, high-tech and other occasions. Copper is also one of the most easily recycled metals among all metals. At present, recycled copper accounts for about 40% of the world's total copper supply. It is used in various household equipment and In appliances, copper is used to conduct electricity and heat. Copper is also used in communication, water and gas transportation, and roof construction. Copper can also be used as a fungicide to protect plants and crops. Copper alloys, such as bronze, can be used in art Such as the casting of statues. Copper is widely used in electrical systems. Its strength, ductility and corrosion resistance make it an excellent conductor for building circuits. It is also used as high, medium and low voltage power cables, or in the manufacture of electric motors. and transformer materials. The International Copper Study Group pointed out that although optical fibers have replaced copper in some communication systems, copper is still the preferred material in the "last mile" or segment. In personal computers and hardware, Copper wiring cables are widely used. In roof construction, it is worthwhile to use copper in order to resist extreme climates. Copper exposed to such climates forms patina (basic copper carbonate) on the surface, which is the application of copper Features. Copper and brass are widely used in tap water piping systems, making the system more resistant to bacteria.
