Topcoat: Amino baking enamel, thickness 17～25μm, drying temperature (100±5)℃, drying time 30～40 minutes,
Topcoat requirements: no obvious unevenness on the surface, slight gradual curvature is allowed, smooth, no variegation, no serious orange peel, no more than 5 impurities per 100 square centimeters, no dirt, scratches, bubbles, Pinholes, flow marks, etc.; adhesion ≤1 level
The spraying robot paint supply system is arranged in the paint delivery room. Paint types: one epoxy primer (solvent-based paint), two topcoats (acrylic polyurethane topcoat, amino baking enamel) (solvent-based paint), two cleaning agents. The paint supply system transports materials, pressure regulators, etc. to the spraying station by storage tanks, diaphragm pumps, agitators, and delivery pipelines, and the supply is mainly transported in a circulating manner. The solvent supply system transports materials and pressure regulators to the spraying station by the storage tank, diaphragm pump, and delivery pipeline. The feed tank is used to store paint and solvent, and the feed tank is equipped with a pneumatic agitator. The paint supply tank is made of stainless steel, and the lid is equipped with a stainless steel quick non-sparking lock to ensure that the lid is in the closed position. The paint tube adopts Teflon tube to ensure that it is not corroded by paint and thinners and is durable. The pressure regulator, back pressure valve, and color change valve are selected from well-known brands, and the parameters should meet the requirements of the system.
