Abstract

The invention relates to a novel high-strength high alumina porcelain insulator. The novel high-strength high alumina porcelain insulator is prepared from the following raw material formula in parts by weight: 8 to 12 parts of smolmitza, 15 to 20 parts of high bauxite, 10 to 15 parts of Zhang village soil, 20 to 30 parts of aluminum oxide, 8 to 10 parts of Jingyang soil, 5 to 8 parts of white clay, 6 to 10 parts of Zuoyun soil, 5 to 10 parts of potassium feldspar, 7 to 15 parts of Qingcaoling soil, 15 to 20 parts of Boai clay, 5 to 10 parts of feldspar, 1 to 5 parts of Ninghai soil and 1 to 5parts of Xinhui soil. By adopting Jingyang soil, high bauxite and smolmitza, the ball milling time is shortened, and not only can the cost be reduced, but also the process performance can be improved;and meanwhile, the problems that different conductive layers are formed inside a porcelain part when ions migrate, leading to non-uniform distribution of an electric field and breaking down an insulator under the long-time action of a DC electric field can be solved.

Description

technical field [0001] The invention relates to the field of insulators, in particular to a novel high-strength high-alumina porcelain insulator. Background technique [0002] Electric porcelain billet refers to a mixture of clay raw materials, flux raw materials and other raw materials (quartz, high alumina raw materials or other mineral raw materials) in a certain proportion, which is ground and mixed into mud for billet making. The mud is simply referred to as billet. [0003] When determining the ratio of various raw materials, it must be ensured that the blank can meet the technical performance required by the electric porcelain production process and the physical performance requirements of the fired porcelain. The technological performance of the billet before firing only depends on the quality and dosage of the clay raw material, while the firing process of the billet mainly depends on the flux raw material. [0004] The long-term aging problem of electric porcelai...
