Method for recycling enamel waste

Abstract

The invention relates to a method for recycling enamel waste. The method comprises the following steps of (1) collecting enamel waste slurry splashed in the production and spraying process and enamelwaste slurry washed from unqualified enamel products, and putting the enamel waste slurry into a waste slurry pool for later use; (2) collecting unqualified enamel solid wastes, removing foreign matters, slurrying, and adding into a waste slurry pool according to a ratio of 30%; (3) bagging and draining the solid matters in the waste slurry pool by using a packaging bag in a production intermittent period, cutting the solid matters after the solid matters are clustered, and sorting out foreign matters; (4) analyzing the chemical components of the solid matter prepared in the step (3), and classifying according to the chemical components of normal glaze to be sprayed; and (5) removing impurities from the solids, purifying, adding the purified solids into normal glaze with similar chemical components according to a ratio of 30%, and adjusting the chemical components of the glaze to be qualified so that the glaze is be used for glaze spraying of the secondary part of the enamel product. According to the method, the purpose of recycling the enamel solid waste is achieved, and meanwhile the enamel solid waste treatment problem is solved.

Description

technical field [0001] The invention belongs to the technical field of enamel spraying technology, in particular to a method for recycling enamel waste. Background technique [0002] Enamel is an inorganic glass enamel coated and fired on the surface of a metal base. Enamel coating on the metal surface can prevent the metal from rusting, so that the metal will not form an oxide layer on the surface when it is heated and can resist the erosion of various liquids. Therefore, it has been sought after by consumers since the enamel process came out. [0003] Enamel raw materials for enamel mainly include mineral raw materials, chemical raw materials and pigment raw materials. After the above three raw materials are prepared in a certain proportion, they are sprayed on the surface of the metal to be glazed, and then fired at a high temperature to obtain the enamel surface glaze. . However, in the actual production process, there will always be various enamel wastes, such as spl...
