Problems solved by technology

Some raw materials need to be washed to meet the process requirements, which increases the manufacturing cost and has the potential risk of polluting the environment
[0006] Most of the existing processes adopt the method of spraying glaze, which is difficult to clean the atomized glaze slurry, and there is a problem of serious environmental pollution; the quality of the glaze surface is difficult to control, and defects such as flower glaze, crystallization, and uneven glaze surface are prone to occur, thereby Affect the electrical performance of the product
At the same time, in the glaze spraying stage, it is necessary to repeatedly heat and dry the blank and spray glaze. Each heating and drying takes about 24 hours, the production cycle is long, and the energy consumption is high.

Abstract

The invention provides a medium-high-strength insulator material formula, including: 12-18 parts of Banshan mud, 12-16 parts of Jiangchong mud, 13-18 parts of Changfeng mud, 12-17 parts of Morantang mud, and 16-23 parts of Guangdong mud , 3 to 9 parts of Fujian mud, 4 to 8 parts of bauxite, 5 to 11 parts of left cloud soil, and 3 to 10 parts of Hubei mud. There is no need for a large amount of clay or feldspar with high plasticity and high binding force in the traditional formula, and the firing temperature of the blank is reduced to 1280 ° C to 1320 ° C, saving energy; the method of glazing is adopted, and the glaze is fast and pollution-free. The present invention can still ensure high mechanical strength and breakdown resistance in the case of a relatively high sodium ion content (1-5%); compared with the traditional process, the total cost of the method of the present invention is about 45%, and the production cycle The shortening is about 20%, and the obtained insulator has uniform porcelain structure, little dispersion, and high mechanical strength and electric strength.

Description

technical field [0001] The invention relates to the technical field of porcelain insulator preparation, in particular to a medium-high strength insulator material formula and a preparation method thereof. [0002] The percentages involved in the present invention are all mass fractions. Background technique [0003] An insulator is a device installed between conductors of different potentials or between a conductor and a component at ground potential, capable of withstanding voltage and mechanical stress. An insulator is a special insulation control that plays two basic roles in overhead transmission lines: it is used to support and fix the busbar and live conductors, and to provide sufficient distance and insulation between live conductors or between conductors and the earth. Insulators are used to increase the creepage distance, commonly used are porcelain insulators and fiberglass insulators. [0004] Electric porcelain billet refers to a mixture of clay raw materials, ...
