The corrosion degree of copper is calculated: the melting point of copper is 1083 degrees, and the coefficient of linear expansion is 17 * 10-6 degrees Celsius. According to the theoretical calculation method of corrosion degree, the annual corrosion amount is 0.9 microns in the sea salt fog atmosphere. It is envisaged that after 2 millimeter thick copper plates are eroded by 1 millimeters, they will still be able to preserve the original function. The corrosion period of 1 millimeters is 1000 microns, 0.9 for 1265.
The life of the copper staircase?
According to the above calculation method, the service life of copper staircase is at least in 1000 under the condition of proper daily use and maintenance. Compared with wooden doors, iron doors and stainless steel doors, the service life of copper doors is much higher than that of them.
Copper - based buildings, both ancient and modern, are warm, corrosion-resistant, anti - bacterial, anti - oxidant, not easily damaged, longer than wood, more resistant to years than bricks, and copper. Through exquisite examination, exquisite craftsmanship, various shapes and external texture, it can not only bear the elegance of the traditional architecture, but also do not lose the solid material, and waterproof and anticorrosion. The exquisite copper technology is perfectly combined with modern science and technology, allowing the limited space to emit infinite air. Therefore, excellent copper staircase, as a symbol of noble status, will become the ultimate representative of high-end villa products.
