Abstract

PURPOSE:To provide a solar heat collecting panel manufactured at low cost and having a sufficient corrosion resistance and a sufficient solar heat absorbing performance by providing on a base plate a film made of a non-crystal structure of metal-semimetal and a solar heat absorbing film layer using a black plating method. CONSTITUTION:A base plate 1 is a plate such as an iron plate, a carbon steel plate or the like which is low in cost and capable of being plated. On said base plate 1, a plated layer excellent in corrosion resistance of a first layer 2 is provided. This plate layer is made of a metal-semimetal non-crystal structure having an eutectic composition consisting of one or more of members selected from the group consisting of Ni-P Ni-W, Ni-Se, Ni-B, Ni-Mo, Cr-P, Cr-W, Cr-Se, Cr-B and Cr-Mo. Further, the film thickness of the first layer is preferably in the range of approximately 0.5-100mum. On the first layer, a black plated film layer excellent in the solar heat absorbing function is provided as a second layer 3. The black plate layer is made of one or more of members selected from the group consisting of Cr, CrO3, Ni-Zn-O, Ni-Zn-S, Zn-O, Zn-S, Ni-O, Ni-S and the like. The film thickness of the black plate layer is preferably in the range of approximately 0.5-20mum. As a black Cr plating method, for example, electron diffracted materials of a chromonix bath, a tetrachromate bath or an ordinary decorative sergeant bath, are subjected to anodic oxidation.

It refers to an amorphous structure of a metal-metalloid having a eutectic composition of 11 or 211 or more. Further, the thickness of the second shield is preferably α5 to 100 μmri degrees. If α is less than 5 μm, the corrosion resistance is inferior to that of conventional stainless steel substrates, which is not preferable. Moreover, if it is 100 μm or more, bending workability deteriorates, which is not preferable. The plating method is preferably one using m5f9c pulse electrolysis, but is not necessarily limited to this method.
