Abstract
The invention discloses a brown glaze for high-strength electric porcelains. The brown glaze for the high-strength electric porcelains comprises the following components by weight percent: 15 to 20 percent of feldspar powder, 8 to 10 percent of Kuancheng soil, 5 to 8 percent of talcum powder, 18 to 20 percent of silica powder, 6 to 8 percent of limestone, 20 to 23 percent of red soil, 1.5 to 3 percent of dichromium trioxide, 8 to 10 percent of manganese dioxide, 2 to 3 percent of ferric oxide and 1 to 2 percent of deflocculant. The brown glaze for the high-strength electric porcelains can be widely applicable to domestic various electric porcelain blanks of the high-alumina system and the medium-alumina system, and the performances of the brown glaze reach and exceed the performance requirements of V-type porcelains in GB8411; and meanwhile, the strength of the electric porcelain products adopting the brown glaze reaches above 230 MPa, so that the brown glaze can fully meet the requirements of a 220-1,000 KV power transmission and transformation system, is a novel brown glaze for electric porcelains widely suitable for production of high-strength electric porcelain products and fills the blank of the domestic brown glaze due to the wide application range.
Description
One, technical field
The invention belongs to the electroceramics technical field, be specifically related to a kind of high strength electroceramice palm fibre glaze.
Two, background technology
Along with the high speed development of electric utility, the improving constantly of voltage range, the kind of China's high pressure and ultra-high voltage porcelain insulator is also of all kinds, and voltage range distributes very extensive from 110KV～1000KV.But various insulators are made by different sorts electroceramics base substrate usually, and the structure of its product is formed all inequality, especially widely different on its chemical ingredients, makes that various types of insulator coefficient of expansion difference is bigger, and this requirement to its surperficial glaze is also just more and more higher.At present, the kind of this type of glaze product is a lot, but adaptability is generally on the low side, does not have a kind of glaze can well adapt to the electroceramics base substrate of most of kinds.
Three, summary of the invention
The purpose of this invention is to provide a kind of adaptability height, can adapt to the high strength electroceramice palm fibre glaze of the electroceramics base substrate of most of kinds.
For achieving the above object, the technical solution used in the present invention is: this palm fibre glaze comprises following component and per-cent: Feldspar Powder 15-20%; Wide city soil 8-10%; Talcum powder 5-8%; Ground silica 18-20%; Limestone 6-8%; Laterite 20-23%; Chromium sesquioxide 1.5-3%; Manganse Dioxide 8-10%; Ferric oxide 2-3%; Defloculating agent 1-2%.
Above-mentioned defloculating agent is Starso or water glass.
Above-mentioned laterite can be the Jiangxi laterite that originates in China Jiangxi Province.
The manufacture craft of manufacture craft of the present invention and other electroceramics palm fibre glaze is basic identical, all adopts wet ball grinding technology.
The physicals of electroceramics palm fibre glaze of the present invention is as follows in the course of processing:
As can be known from the above table, glaze slip subject range broad according to the present invention's preparation, especially linear expansivity can be complementary with most electroceramics base substrate, can generally be applicable to the electroceramics base substrate of domestic various high alumina, middle aluminium system, its every performance has has met and exceeded the performance requriements of V class porcelain among the GB8411.Simultaneously, adopt the electroceramics intensity of the electrotechnical porcelain product of electroceramics palm fibre glaze of the present invention to reach more than the 230MPa, can satisfy the requirement of 220-1000KV power transmission and transformation system fully, be a kind of novel electroceramics palm fibre glaze of producing the high strength electroceramice product, wide blank that remedies domestic this series products of its adaptability of generally being applicable to.

Embodiment 2:
The electroceramics palm fibre glaze of making according to present embodiment is respectively applied for the 1# and the 2# electroceramics base substrate of different intensity grades, and its main electroceramics performance is as follows:
Folding strength: 1#155MPa (no glaze); 223MPa (glaze is arranged)
2#142MPa (no glaze); 189MPa (glaze is arranged)
Cold and hot performance: 1#185K (no glaze); 235K (glaze is arranged)
2#168K (no glaze); 217K (glaze is arranged)
Microhardness: 1#762MPa
2#732MPa
According to present embodiment, small serial production goes out the electric porcelain insulator product of 220～1000KV grade, and its bending resistance destruction value is not less than 55KNm, in crush the bad 3.7MPa that is not less than.
