Preparation process of high-strength porcelain insulator for power transmission

Abstract

The invention relates to the field of insulating materials, in particular to a preparation process of a high-strength porcelain insulator for power transmission, which comprises the following steps: uniformly mixing raw materials of a blank layer; deionized water accounting for 50% of the mass of the raw materials of the blank layer is added, ultrasonic treatment is conducted for 5-8 min, and blank layer slurry is obtained; after iron is screened out from the blank layer slurry, mud is squeezed, obtained mud cakes are extruded in a vacuum pug mill, obtained mud sections are subjected to electric drying in the shade, and green bodies are obtained after drying; uniformly mixing the raw materials of the porcelain glaze layer, adding deionized water which accounts for 30% of the mass of the raw materials of the porcelain glaze layer, and uniformly stirring to obtain the porcelain glaze layer slurry. And glazing, firing and cementing the porcelain glaze layer slurry on the green body to obtain the high-strength porcelain insulator for power transmission. The mixing process of the raw materials of the blank layer and / or the raw materials of the porcelain glaze layer is carried out in a multi-dimensional mixer. The convenience of preparing the high-strength porcelain insulator for power transmission is improved, the process difficulty is low, the production efficiency is high, the texture uniformity of the porcelain insulator can be improved, and the product quality is improved.

Description

technical field [0001] The invention relates to the field of insulating materials, in particular to a preparation process of a porcelain insulator for high-strength power transmission and the porcelain insulator. Background technique [0002] Porcelain insulators are insulators made of electrical ceramics. [0003] An insulator is a device that can withstand voltage and mechanical stress installed between conductors of different potentials or between conductors and grounding members. There are many types of insulators in different shapes. Although the structure and shape of different types of insulators are quite different, they are all composed of two parts: insulating parts and connecting fittings. [0004] Insulators are special insulation controls that can play an important role in overhead transmission lines. Insulators were mostly used for utility poles in the early years, and gradually developed into high-voltage wire connection towers with many disc-shaped insulat...
