BACKAluminium tube
Copper pipe for air conditioning
Description:Copper tube, a non-ferrous metal tube. It's pressed and pulled seamless.
parameters
Copper tubes are much more widely used than pure iron. Every year, 50% of copper is purified into pure copper by electrolysis, which is used in the electrical industry. The copper here is indeed very pure, containing more than 99.95% copper, a very small amount of impurities, especially phosphorus, arsenic, aluminum, will greatly reduce the conductivity of copper. The oxygen content of copper (copper smelting is easy to mix a small amount of oxygen) has a great effect on the conductivity, and the copper used in the electrical industry must generally be oxygen-free copper. In addition, impurities such as lead, antimony and bismuth will prevent copper crystals from bonding together, resulting in thermal embrittlement, which will also affect the processing of pure copper. This high purity pure copper, general electrolysis refining: the impure copper (that is, crude copper) as the anode, pure copper as the cathode, with 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. Copper thus refined; The purity can reach 99.99%. Copper is a relatively pure kind of copper, generally can be approximately considered to be pure copper, electrical conductivity, plasticity are better, but the strength, hardness is poor.
introduction
Compared with the general plastic pipe, it can be found that the main material of the plastic pipe contains plasticizer and other chemical additives, which is easy to cause the escape or the hardening and embrittlement of the plastic with the change of time and temperature. The copper tube has no plastic tube of various modifiers, additives, additives and other chemical composition, the nature is very stable. And the E. coli in the water supply can not continue to multiply in the copper pipe, more than 99% of the bacteria in the water into the copper pipe five hours after the thorough killing
