Problems solved by technology

[0002]At present, the enamel products on the market generally include blank making, glaze making, enamelling, firing, decoration and other processes. The bottom glaze is applied first, and then the top glaze is applied after firing, which is the traditional two-enameling and two-firing process. The traditional two-enamelling and two-firing process requires two sinterings, which does not meet the requirements of energy saving and emission reduction. National policies have caused economic losses to enterprises, with high costs and low benefits. This problem has always plagued the development of enterprises.

Abstract

The invention belongs to the technical field of the production of an enamel product, and particularly relates to a double-spray one-sintering low-temperature sintering spraying technology. The spraying technology is characterized in that a ground coat is firstly coated on a metal blank in the production process of the enamel product, then a cover glaze is coated, and finally the enamel product is sintered in one step, therefore, the one-time sintering procedure can be simplified, the production cost of the enterprise can be effectively reduced, the production efficiency of the enamel product can be increased, the production flow can be saved, and the national requirement of energy conservation and emission reduction also can be met. Clay and different electrolytes are unnecessary to add in the ground coat and the cover glaze, the sintered enamel surface is smooth and compact, the porous rate is low, miscellaneous points and different colors can be obviously reduced, the situation that the exhaust direction is gradually escaped and dispersed from the non-enamel surface in the traditional technology and an air passage directly leading to the enamel surface is difficult to form can be well solved, and the appearance defects such as pin holes, bubbles and the like can be avoided.

Description

Technical field: [0001] The invention belongs to the technical field of production and manufacture of enamel products, and in particular relates to a low-temperature firing spraying process with two sprays and one fire. Background technique: [0002] At present, enamel products on the market generally include processes such as billet making, glaze making, enamelling, firing, and flower decoration. The base glaze is first applied to the pre-stamped or cast metal blank, and the top glaze is applied after firing. And then firing, that is, the traditional two-bore and two-fire process, the traditional two-bore and two-fire process needs to be sintered twice, which is not in line with the national policy of energy saving and emission reduction, and causes economic losses to the enterprise. Low efficiency, this problem has been plagued by the development of enterprises. Invention content: [0003] In summary, in order to overcome the deficiencies of the existing technical p...
