Abstract

The invention relates to a method of selecting and preparing raw materials of 550kN-grade suspension-type porcelain insulator glaze. A 550kN-grade porcelain insulator glaze green body can be prepared by selecting 6-20 percent of kaolinite clay, 7-15 percent of talc, 20-40 percent of feldspar, 25-40 percent of refined quartz, 10-20 percent of calcined bauxite, 3-15 percent of calcium carbonate, 0-10 percent of medium porcelain powder and 0.001-1 percent of sodium silicate. The granularity of the clay is 20-40mu, and the granularity of other raw materials is 180-200mu.The glaze is prepared by using the raw materials and the method has good flowability and little multiviscosity, and is convenient for glazing operation; and the glazed and sintered porcelain green body has bending strength of being improved by 25-40 percent, therefore, the electromechanical properties and the insulating property of a porcelain insulator are improved and the quality of the porcelain insulator product is guaranteed.

Description

technical field

[0001] The invention relates to an amorphous and aluminosilicate material, which is especially suitable for the selection and preparation of glaze raw materials for 550kN grade suspension porcelain insulators. Background technique

[0002] With the implementation of the strategy of "power transmission from west to east, national interconnection, and mutual supply between north and south" in my country, the country attaches great importance to the development of ultra-high voltage and ultra-high voltage technology and the localization of supporting equipment. In the future, my country's high-tonnage, large-capacity long-distance transmission lines will More and more, the future demand for 550kN class suspension porcelain insulators will also increase.

[0003] Suspension porcelain insulator is a kind of aluminosilicate material composed of nearly 20 kinds of minerals mixed with various clay raw materials, prepared and sintered by complex process. The porcelain ...
