Abstract

La présente invention concerne un procédé de pulvérisation de peinture antiadhésive pour une poêle antiadhésive présentant un motif irrégulier, et la présente invention consiste d'abord à effectuer un sablage sur la surface interne d'un produit de poêle semi-fini, permettant ainsi une augmentation de la force d'adhérence entre le produit semi-fini et une couche de revêtement ainsi qu'une amélioration de la durabilité d'un film de revêtement, puis à pulvériser une peinture antiadhésive à base d'huile et à polir un motif en saillie au moyen d'un papier abrasif de manière à éliminer la couche de revêtement à base d'huile du motif en saillie, permettant ainsi d'améliorer l'effet décoratif d'un motif en saillie, et enfin à pulvériser une peinture antiadhésive de surface à base d'huile sur la casserole semi-finie, permettant ainsi d'améliorer l'effet antiadhésif du motif en saillie du produit. Une poêle antiadhésive fabriquée par la présente invention est robuste et présente une excellente durabilité, et peut produire un effet antiadhésif complet et à long terme puisque sa couche de revêtement à base d'huile est protégée par une couche de revêtement de surface à base d'huile, résout le problème du procédé classique dans lequel un motif en saillie est fixé ou la couche de revêtement d'un motif en creux est facilement détachée, réduit l'écaillage de la peinture causé par une spatule et améliore complètement l'effet antiadhésif, la durée de vie et la propriété esthétique d'une poêle.
