Abstract:
     The nature of the claimed technique is that, by use of sulfuric acid and Na2SiO3 (water glass) and other additive components as treatment solution for anodic oxidation of aluminising films on non-metallic base materials (esp. glass and ceramic) at ordinary temp. and certain electric current and voltage. The oxidized film then undergoes a closing treatment by one of the three methods provided in this invention. That way, a wear and corrosion-resistant, weather-proof and insulated mirror oxidation film is resulted, which has a high visible light reflectivity (about 85%). The claimed technique has a simple process, low cost and high production efficiency.
