Abstract

The invention discloses a piano wire-drawing and matte coating process. The process comprises the following steps of: (1) spraying poly ethylene (PE) paint onto each piano workpiece and polishing the piano workpiece with sand paper from the crude sand paper to the fine sand paper until 600# sand paper is used; (2) spraying nitrolacquer onto each piano workpiece, polishing the piano workpiece withthe sand paper and cleaning the workpiece; (3) polishing each piano workpiece with a non-woven fabric and cleaning the workpiece; (4) polishing each piano workpiece with a steel wool and cleaning theworkpiece; (5) coating wax on the piano workpieces with colors except black; and (6) wiping each piano workpiece with 'Chachakelin' (a foam with extremely high detergency), and wiping the piano workpiece until the piano workpiece is dry, thus finishing the process. The surface of the processed piano is uniform, straight, fine and soft in sanded textures.

Description

technical field [0001] The invention relates to a piano surface processing technology, in particular to a piano wire drawing matte finishing process. Background technique [0002] The piano is an elegant and noble instrument, and the requirements for the appearance, surface quality and gloss of the piano are very high. For the brushed matte finishing process, the uniformity, straightness, fineness, softness, and gloss of the sand path directly determine the appearance and texture of the piano. A little defect in the sand path will lead to a decrease in the sale price of the piano. Make a very big difference. Therefore, at present, piano manufacturers are testing and improving the brushed matte finishing process. Contents of the invention [0003] In order to overcome the deficiencies in the prior art above, the present invention provides a piano wire drawing and matte finishing process. After processing, the sand path on the surface of the piano is uniform, straight, fin...
