Troughed solar condenser making method

Abstract

The invention provides a troughed solar condenser making method which is high in processing speed and silver layer thickness. The method includes the steps: (1) washing and polishing; (2) sensitizing; (3) silvering; (4) coppering; (5) painting; (6) drying; (7), cleaning silver containing residues, namely using a sponge roll with FeCl3 solution to clean the silver containing residues; and (8) discharging sheets after cleaning and drying to obtain finished products. All steps are completed during conveying. The troughed solar condenser making method has the advantages that surface adhesive force can be increased by means of sensitization before silvering; the silver layer is high in thickness and effective in condensation after silvering; by means of the silver containing residue cleaning step, the paint surface is smooth; and since all steps are completed during conveying, rapidness and high efficiency are achieved.

Description

technical field [0001] The invention relates to a mirror manufacturing method of a solar trough condenser mirror. Background technique [0002] Traditional silver mirror manufacturing methods generally include: sensitization, silver plating, copper plating, painting, drying and other steps, such as the manufacturing method disclosed in the invention patent application with patent application number 201010286964.9. Widely used, because of its arched shape, it is significantly different from flat glass in terms of transmission and requirements for each step of operation. In addition, the thickness of the silver layer needs to reach 1300 Above, the method in the aforementioned patent application cannot be applied to the manufacture of solar trough concentrators; there may be silver-containing residues in the finished products made by the prior art, which not only affects the flatness, aesthetics and reflection effect of the silver mirror, but also causes waste of resources If...

[0002] Traditional silver mirror manufacturing methods generally include: sensitization, silver plating, copper plating, painting, drying and other steps, such as the invention patent with the patent application number 201010286964.9 According to the manufacturing method disclosed in the application, the solar trough concentrator is widely used in the field of solar power generation. Because of its arched shape, it is significantly different from flat glass in terms of transmission and requirements for each step of operation. In addition, the thickness of the silver layer needs to reach 1300 Above, the method in the aforementioned patent application cannot be applied to the manufacture of solar trough concentrators; The existence of silver-containing residues not only affects the flatness, aesthetics and reflection effect of the silver mirror, but also causes waste of resources. If a step for cleaning silver-containing residues can be set after painting and drying, the quality of the silver mirror will be greatly improved, and the silver-containing residues will Can be recycled
