A kind of aluminum high voltage electric porcelain and its production process

Abstract

The invention relates to aluminum high-pressure electrical porcelain. The aluminum high-pressure electrical porcelain comprises a raw material and a glaze material, wherein the raw material comprises the following components by weight percent: 57 percent of bauxite with aluminum content being more than 86 percent, 11 percent of green grass clay with aluminum content being 20 percent and magnesium content being 10 percent, 10 percent of black clay with aluminum content being 25 percent, 6 percent of feldspar powder and 16 percent of sulfonated soil with aluminum content being 22 percent; and the glaze material comprises 5 percent of manganese dioxide, 8 percent of zirconium oxide, 3 percent of chromium oxide, 5 percent of sulfonated soil, 9 percent of Triratna, 15 percent of moisture gauge, 5 percent of sodium humate, 15 percent of quartz, 5 percent of calcite, 25 percent of black clay and 5 percent of kaolin. The production process comprises the steps of batching, ball milling, screening, mixing, press filtering, smelting, aging, staling, clay refining, drying in shade, fettling, drying, glazing, sintering, cutting, grinding and cementing. By adopting the aluminum high-pressure electrical porcelain and the production process thereof, the problems of the existing high-pressure electrical porcelain product that the mechanical strength is low and the breaking strength is low can be solved. The advantages of low cost, high mechanical strength and high breaking strength can be achieved. The process is simple and easy to operate and control.

Description

technical field [0001] The invention relates to an aluminum high-voltage electric porcelain and a production process thereof. Background technique [0002] High-voltage electric ceramic materials are an important part of high-voltage power transmission and transformation lines. In order to meet the needs of ultra-high voltage, ultra-high voltage, high-current, and long-span power lines, domestic and foreign competitions have been launched to improve the power, heat and electrical properties of electric ceramics. Scientific research, the results of which continue to emerge. [0003] 1) Ordinary electric porcelain materials Early electric porcelain was mainly feldspar porcelain, which used quartz, feldspar, and clay as raw materials, and the porcelain composition was 10%-20% quartz, 10%-20% mullite, 60%-80 % porosity and glassy phase. Ordinary feldspar porcelain has coarse particles and good formability, but low mechanical strength, and the flexural strength is only 30MPa-50...
