Problems solved by technology

[0002] At present, in the production process of electric porcelain insulators at home and abroad, the glaze on the surface of the insulator is mostly made of silicate high-temperature raw material glaze, and its composition is between feldspar glaze and lime glaze. The glaze slurry is usually prepared by wet ball milling. The density of different components in the glaze slurry is different, and the particles with higher density are prone to stratification and precipitation, which will lead to quality problems in the glaze layer due to changes in the concentration of the glaze slurry during the glaze application process.

Abstract

The invention discloses a suspending agent specially used in the preparation and use process of electric porcelain surface glaze in the electric porcelain insulator production process. The suspending agent comprises 0.5-1.5wt% of industrial grade polyacrylamide, 1-2wt% of sodium acrylate, 1-3wt% of sodium hexametaphosphate and 93.5-97.5wt% of purified water. A preparation method of the suspending agent mainly comprises the following steps: dispersing and mixing sodium hexametaphosphate, polyacrylamide and purified water in an electrothermal reactor, adding sodium acrylate, continuously mixing, discharging, and packaging. The suspending agent can substantially reduce the layering precipitation speed of a glaze slip, improves the stability of the glaze slip by about 5 times, only accounts for about 1 / 10 of a present common amount, has protruding performances and substantial benefits, and also has the characteristics of simple synthesis process and convenience in storage and use.

Description

Technical field [0001] The patent of the invention relates to a special suspending agent for the preparation and use of the surface glaze of the electric porcelain body during the production process of the electric porcelain insulator. Background technique [0002] At present, in the production process of electric porcelain insulators at home and abroad, the surface glaze of the insulator is mostly silicate high-temperature raw material glaze. Its composition is between feldspar glaze and lime glaze. The glaze slurry is usually prepared by wet ball milling. The density of different components in the glaze slurry is different, and the particles with higher density are prone to delamination and precipitation, which in turn leads to quality problems in the glaze layer due to changes in the glaze slurry concentration during the glazing process. [0003] At present, in order to prevent the sedimentation of the glaze slurry, the suspending agent or anti-precipitation agent used by the ma...
