Purple golden vacuum tube

  The coating of purple golden vacuum pipe is also using the three target of sputtering principle, namely the target aluminum, copper and stainless steel target target, but when the reduction of layer coating deposition rate is much lower, coating time is relatively much longer, minus the layer than three tenors tube aluminum nitride to pure, absorb the sun than relative or some. Hot water circulation characteristics is fast, hot start soon.
