Abstract
The invention discloses a surface treatment method for a solar vacuum stainless steel tube. The surface treatment method comprises the following steps: derusting treatment on the stainless steel tube; deoiling treatment; electrolytic polishing treatment; cleaning treatment; drying treatment; and vacuum coating of a metal film. Test results can show that a complete film layer is formed after the stainless steel tube subjected to surface treatment is coated with the film, and the adhesive force is very strong. After the stainless steel tube is coated with the metal film, the hydrogen permeation preventing capability of the coated stainless steel tube is enhanced, and thus the vacuum degree is easier to keep. A copper layer can serve as a metal bottom layer of the solar vacuum tube, and since the surface is compact, the hydrogen permeation preventing capability of the stainless steel tube is enhanced.
