Embodiment Construction

[0019] Following is the concrete process step of implementing the present invention:

[0020] First, choose kaolinite clay 10-15%, talc 10-15%, feldspar 25-35%, refined quartz 25-35%, carbonate 5-10%, ordinary porcelain powder 1-8%, water glass 0.1-0.5%, calcined bauxite 10-15%. The particle size of the clay raw material is 20-40 mesh, and the particle size of other raw materials is 180-200 mesh. After mixing evenly, ball milling, and then component analysis. Its compositional analysis data and particle size are expressed as follows:

Abstract

The invention discloses a method for the selection and the preparation of the raw materials of a high-strength suspension porcelain insulator glaze. The raw materials comprise kaolinite type clay, talcum, feldspar, refined quartz, carbonate, porcelain powder, water glass and calcined alumina. The invention is characterized in that the kaolinite type clay is 10 to 15%, the talcum is 10 to 15%, the feldspar is 25 to 35%, the refined quartz is 25 to 35%, the carbonate is 5 to 10%, the porcelain powder is 1 to 8%, the water glass is 0.1 to 0.5% and the calcined alumina is 10 to 15%. The particle size of each clay raw material is 20 to 40 mushes, the particle size of other raw materials is 180 to 200 mushes. The bending strength of porcelain blank can be improved by 25 to 40% after being glazed by the glaze, the sintering temperature of the porcelain insulator after being glazed is 1200 to 1350 DEG C.

Description

technical field [0001] The invention relates to an aluminosilicate material, which is particularly suitable for the selection and preparation of high-strength suspension porcelain insulator glaze raw materials for AC transmission lines. 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 matching suspension porcelain insulators for transmission lines will also increase. According to statistics from relevant departments: the annual domestic demand for suspension porcelain insulators is about 10 million tons. [0003] Suspension porcelain insulator is...
