Surface treatment process of pot

Abstract

The surface treatment process of the pot comprises the following steps: S1, oil removal: carrying out oil removal treatment on the inner surface of a pot body needing to be treated by using a degreasing agent in a spraying state; s2, chemical solution spraying, wherein the chemical solution is atomized and coated on the inner surface of the pot body needing to be treated through a spray gun; s3, inner spraying, wherein PTFE or water-based ceramic is sprayed to the inner surface of the pot body needing to be treated through an air spray gun; and S4, high-temperature curing: after the pot body sprayed with the PTFE or the water-based ceramic is heated, the PTFE or the water-based ceramic is cured to form a non-stick coating film. The surface of a base material can be uniformly covered with the coating through chemical solution spraying, the coating and the base material form certain roughness through chemical bonds, and then the requirement of water-based ceramic spraying construction or PTFE spraying construction for the surface roughness of the base material is met. The process has the following two advantages: firstly, the sand blowing procedure is reduced, and the process cost is saved; and secondly, the phenomenon that the staff work in a dust environment to cause the lung silicon disease is avoided.

Description

technical field [0001] The invention relates to a pot surface treatment process. Background technique [0002] In the prior art, all substrate surfaces to be coated with internal coatings (water-based PTFE coatings and ceramic coatings) require white corundum, brown corundum, etc. to form on the surface of the coated substrate under the action of compressed air. A certain roughness, that is to use the sand blowing process. Without the roughening of this step, the undercoat will not be able to bond firmly to the substrate to be coated, resulting in peeling between the coating and the substrate. The result of the above process: when white corundum, brown corundum, etc. roughen the coated substrate under the action of compressed air, the dust environment in this process can easily cause the operator to suffer from pulmonary silicosis. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the surface treatment process of the pot in the p...
