Description

Production process and production device of acid-base-resistant low-VOCs-emission water-based glass glaze

Technical Field

The invention relates to the technical field of glass glaze production, in particular to a production process and a production device of acid and alkali resistant low-VOCs (volatile organic compounds) emission water-based glass glaze.

Background

The glass glaze is still glass in terms of its microstructure, and thus has many of the properties of glass. The glass glaze medium has the advantages of higher dielectric constant, lower dielectric loss, wider working temperature range, stable temperature characteristic and frequency characteristic, higher electric strength resistance, higher chemical stability and thermal stability, certain mechanical strength, lower melting temperature, low price and the like.

Glass glazes generally consist of two parts, a base glaze and a pigment. The base glaze is colorless low-melting-point glass, and the molten colorless low-melting-point glass is directly poured into water for cooling during production, so that the molten colorless low-melting-point glass is water-quenched into small fragments, which are called as frits by the custom of domestic production industry; the pigment is a coloring substance, also called colorant, and is commonly called pigment in domestic factories, and plays a role in preparing the colorless basic glaze into the glazes with different colors. The two materials can be weighed after being manufactured respectively, and are mixed and ground in a ball mill to prepare colored glaze, and the method is called grinding addition; or can be melted together, namely, the coloring oxide is directly added into the raw materials of the base glaze to be melted into a frit, which is called a melting method. When the glaze is used, the glaze is mixed with a blender and other additives to be mixed to a certain viscosity, and then the condition of hand painting or printing is met.
