ZB 17022-1989 "Sewing Machine Painting Technical Conditions" is a mechanical industry standard, specifying the technical requirements for the baking process of sewing machine parts. The content covers the pretreatment of baking paint (surface derusting, degreasing and cleaning), Coating performance indicators (adhesion, hardness, gloss, etc.), baking process parameters (drying temperature, time, coating thickness control), Appearance mass requirements (coating flatness, uniform color, no sagging bubbles) and inspection rules. This standard applies to the baking process of metal parts of sewing machines. By standardizing the baking process and quality control, the coating is ensured to be firm, corrosion-resistant and beautiful, and meets the wear-resistant and stain-resistant needs of sewing machines in daily use. Provide technical basis for the production and inspection of sewing machine baking paint, and help improve the Appearance mass and service life of the whole machine.
