Solar vacuum tube what color is good
Zijin pipe is currently the highest level of vacuum tubes on the market, with rapid heating, high temperature resistance, anti-aging and other characteristicsIt features: Purple tube absorption ratio increased by 15%, decreased 30%-40% emission, high thermal efficiency, fast heating, in the same light condition, the temperature rises faster than the ordinary pipe, high heat efficiency, anti freezing explosion-proof performance significantly.
1, ordinary tube: aluminum ion coating technology2, three high tube: copper ion coating technology3, purple tube: copper ion coating technology, the surface of the purple gold, because we all know that like the purple color can absorb the short wave in the air, short wave of high heat, so the absorption effect is better!
This type of consumer discrimination method of vacuum tube:1, the naked eye, the general tube and the appearance of the three high tube is dark blue, purple tube appearance is dark red2, in the sun from the tube to see, ordinary tube partial blue, three high tube partial red, purple tube is very red (pictured above)
