Title: Forming method of solar heat selective absorption film
Inventor: AIKAWA KAZUO
IPC: F24J2/48
Filed: 1982-06-14
Abstract: PURPOSE:To manufacture a solar-heat selective absorption film which is superior to a selective absorbing power, by electrolyzing Al or Al alloy by alternating current in a solution having a specific pH, containing two kinds or more of metallic salts and thioammonium sulfate, after processing them in an acidic anolyte. CONSTITUTION:Al or Al alloy, treated with a mirror surface finish, is oxidized in an anolyte to form a porous oxidized film of below 2mu on its surface. Next, it is electrolyzed by alternating current in a water solution of which pH is below 4-8, containing more than two kinds of metallic salts such as nitrate or sulfate of Ni or Cu or the like, and thioammonium sulfate. The concentration of electrolyte of thioammonium sulfate is to be 0.2-100g/l, and as for the electrolyzing conditions, the voltage is to be about 30-40V, and the temperature in a bath is to be about 15-40 deg.C. By the multiplied effect of more than two kinds of metallic salts and thioammonium sulfate, not only the precipitation speed of metallic salts is increased, but also a eutectic mixture of metal and sulfur of which apparent density to a color is high can be formed. In such a manner, a colored film which is superior to a solar-heat selective absorption power can be manufactured in a short time with high workability.
