I bought a solar energy, the boss told me that Zijin pipe is better than ordinary pipe... But I do not know, I bought the purple tube is, deep golden yellow (sunshine), there is a blue, relatively poor... I would like to ask you what kind of good?
The naked eye, plain tube and three tube appearance is dark blue, purple tube appearance is dark (see Guangyang) from the tube in the sun, the common tube blue, three tube is red, purple red purple tube tube very in the sun is the golden, look inside is red.
In the new coating materials and production process, in the heating, heat collection, three technical parameters of life are beyond the maximum, 0.97 is the purple tube solar absorption ratio, 11 percentage points higher than the national industry standard, set the theoretical limit of thermal technology has been close to the vacuum tube collector performance, represent the highest level of local the solar power industry.
Zijin tube is a kind of vacuum tube used in solar energy. Using PEPAC multi target interference film technology, add the purple coating, under the same conditions, than the ordinary three high temperature heating faster than 12%, faster heat.
