Solar energy black chrome plate core is the core flat plate solar collector components, materials used high-quality T2 copper belt and copper, copper thickness of 0.1 ~ 0.2mm. Copper plating selective black chrome surface coating, the coating layer having a high absorption rate, low emissivity advantage (Beijing Solar Testing Center report absorption rate: ~ 97% emission rate to 9%) has become the first choice of the country and the major European and American manufacturers of flat Specification: 125 * 1840 * 0.15mm brass and fin ultrasonic welding, welding firm, will not leak welding Weld phenomenon common specifications: 10 * 0.5 * 1886mm head tube and the sub-tube with burn method of brazing welding, high temperature after melting copper electrode head tube and the sub-pipe gap good seal, so that the entire board core through 16BAR water pressure test leakage does not occur can help customers build a variety of products according to different needs of guests. either the fins and welded sub-pipe can also be the core of the whole board to do. packaging using wooden packaging to ensure safe and secure during transport.
