Abstract

The surface enamel spraying technology for the metal pot comprises the following steps that S1, outer sanding is conducted, specifically, bumping damage on the surface of a metal base material is repaired to be smooth through a scouring wheel under high-speed rotation of a sanding machine; s2, oil removal: performing oil removal treatment on the surface of the to-be-treated pan body by using a degreasing agent in a spraying state; s3, spraying enamel slurry: atomizing and coating the enamel slurry on the surface of the pot body to be treated through a spray gun; the enamel slurry comprises the following components: enamel glaze, inorganic pigment, spherical aluminum oxide, spherical silicon carbide, a suspending agent and purified water; and S4, heating and curing: heating the pot body coated with the enamel slurry to form a texture coating film on the surface of the aluminum base material.

Description

technical field [0001] The invention relates to a surface enamel spraying process of a metal pot. Background technique [0002] In the prior art, the surface enamel spraying process of the metal pot has high requirements on the surface treatment process of the base material during the construction. In order to remove the bumps on the surface of the metal substrate, a cleaning wheel is generally used for external sanding treatment. In order to reduce the resistance between the metal substrate and the cleaning wheel during the sanding process, the cleaning wheel manufacturers will add polishing wax when producing the cleaning wheel. It is precisely because the polishing wax is added to the cleaning wheel that part of the polishing wax will be cut into the metal substrate during the sanding process. After normal degreasing or cleaning, it cannot be removed at all, especially when the texture is relatively soft. aluminum pan. Finally, dense pinholes or shrinkage cavities will...
