Matte colorful enamelled ware enameling and firing technology

Abstract

The invention discloses a matte colorful enamelled ware enameling and firing technology. The matte colorful enamelled ware enameling and firing technology comprises the following steps that firstly, degreasing treatment is conducted; secondly, ground glaze coating and enameling are conducted, a leaching assisting coating agent is sprayed to a clean enamelled ware blank, secondary drying treatmentis conducted, and ground glaze coating and enameling are conducted on the clean enamelled ware blank through a dip-coating manner; thirdly, ground glaze firing is conducted; fourthly, cover glaze coating and enameling are conducted; fifthly, cover glaze firing is conducted; sixthly, color glaze coating and enameling are conducted; seventhly, color glaze firing is conducted; and eighthly, finishedmatte colorful enamelled ware is obtained. Self-made metal degreasing cleaning liquid is adopted in the matte colorful enamelled ware enameling and firing technology, the cleaning speed is high, adsorption can be conducted on the metal surface so that a layer of surface protection film can be formed, and metal is not prone to rusting; and after the blank is subjected to dust removal through the metal degreasing cleaning liquid, thorough flushing is easy. The technology method is easy to grasp, through the reasonable arrangement of various steps and technology parameters of the whole enamelingand firing technology, generation of serious rust spots, bubbles and other defects on the surface of a glaze layer can be effectively avoided, and the quality of the glaze layer of the prepared mattecolorful enamelled ware can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of enamel vessels, in particular to an enamelling process for matte colored enamel vessels. Background technique [0002] Enamel, also known as enamel, is a composite material in which inorganic vitreous materials are condensed on the base metal by melting and firmly combined with the metal. 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. Enamel products are not only safe and non-toxic, but also easy to wash and clean. They can be widely used as eating utensils and washing utensils in daily life, and under certain conditions, enamel coating on the metal body exhibits high hardness and high temperature resistance. Excellent properties such as wear resistance and insulation ma...

AI Technical Summary

Problems solved by technology

Because there is a lot of oil on the surface of the body, it must be removed before enamelling. However, in the existing enamelling process, there are often cracks and rust spots on the surface of the vessel during the subsequent firing process due to improper degreasing and incomplete cleaning. , bubbles (dark bubbles or reboiling bubbles) and other defects
