Embodiment 1

[0036] The metal container of this embodiment is a stainless steel container with a height of 10 cm and a cylindrical side wall. The stainless steel container was placed in a heating furnace and heated for 30 minutes at a heating temperature of 400°C. After the stainless steel is cooled, the inner wall of the stainless steel container is sandblasted with No. 46 emery. The air pressure for sandblasting is 0.6MPa and the sandblasting time is 35s. The roughness of the inner wall of the stainless steel container was detected to be Ra2. The electrostatic spray glaze powder process includes the following steps:

[0037] S311: Provide an electrostatic spray powder system for enamel containers, which includes an electrostatic spray gun and a rotating carrier;

[0038] S312: Fix the metal container on the carrier, the metal container is electrically connected to the carrier, and the carrier is grounded;

[0039] S313: Adjust the inclination angle of the electrostatic spray gun so that the ...

Abstract

The invention discloses a manufacturing process of an enamel container and an enamel container. The manufacturing process comprises the following steps of removing oil stains on the inner wall of a metal container; carrying out sandblasting on the inner wall of the metal container; electrostatically spraying glaze powder to the inner wall of the metal container; and putting the metal container ina sintering furnace for sintering. The enamel container obtained through the manufacturing process of the enamel container is uniform in the enamel layer thickness and smooth in the surface, and doesnot have the defects of scorching, porcelain explosion, powder accumulation and the like.

Description

Technical field [0001] The invention relates to the field of enamel production, in particular to an enamel container production process and an enamel container. Background technique [0002] An enamel container is a device formed by melting and condensing an inorganic material on the surface of a base metal and firmly bonding with the metal. The container includes a bottom and a side wall surrounding the bottom, such as a cup. The traditional enamel preparation process includes glaze preparation, body preparation, enamelling, drying, firing and inspection. The preparation of the glaze is to pre-mix dry glaze powders such as silicate, boron oxide, alumina, alkali metal oxides and water to form a glaze slurry. Enameling is to coat the glaze slurry on the surface of the body. The disadvantages of the prior art are: (1) the glaze slurry is often not evenly coated on the body, resulting in uneven thickness of the enamel; (2) the drying process takes up working time and prolongs the p...
