Abstract
The invention discloses a hyperhigh-strength electric porcelain formula, which comprises the following parts: 8-12% Fraxinus mandshurica clay, 9-13% feldspar powder, 37-47% sintered vitriol powder and 6-10% zhangwu clay, 5-10% faku clay, 4-8% kuancheng clay, 5.5-8.5% baofeng clay, 4-8% yongji clay and 0.5-1.5% modified alta-mud. Each property of electric porcelain reaches and exceeds V-typed standard in the GB8411 with transverse strength at 165-170Mpa without glaze or 221 231Mpa with glaze, which supplements the blank of this kind of product in our country.
Description
One, technical field
The invention belongs to the electroceramics technical field, be specifically related to a kind of prescription of producing superhigh intensity electric ceramic.
Two, background technology
Along with developing rapidly of electric utility, improving constantly of voltage range, China is also more and more higher to the requirement of the porcelain insulator that is used for high pressure and ehv power transmission system, and the porcelain performance of existing porcelain insulator has not reached requirement, the folding strength of porcelain particularly, generally only on 140Mpa～160Mpa level, can not satisfy the requirement of 220～1000KV power transmission and transformation system at all.At present, this series products just can only satisfy domestic demand by import, like this, not only causes a large amount of losses of fund, but also has seriously hindered the development of electric utility.
Two, summary of the invention
The purpose of this invention is to provide a kind of electric ceramic formulation, use electrotechnical porcelain product good insulation preformance, physical strength height that this prescription is produced.
A kind of formula of high strength electroceramice of the present invention, component that is comprised and weight percent are:
Cortex Fraxini mandshuricae clay 8～12% Feldspar Powders 9～13%
Burn aluminite powder 37～47% Zhangwu clays 6～10%
Faku County's clay 5～10% wide city clays 4～8%
Baofeng clay 5.5～8.5% Yongji clays 4～8%
Modified alta-mud 0.5～1.5%.
The manufacture craft of manufacture craft of the present invention and other electroceramics is basic identical, adopt wet moulding, technical process is as follows: once batching → wet ball grinding → second batch → wet ball grinding → deironing → the press filt of sieving → old → vacuum extrude → dry in the shade → repaired biscuit → light base dries in the shade → dries → glazing on sand → loading of kiln → roast → porcelain inspection → cutting and grinding → mucilage binding → health → inspection → finished product put in storage.
The physicals of blank such as following table in the above-mentioned technology:
As can be known from the above table, the bending strength according to the dry body of this formulated can reach 5.20～6.29MPa.
Use the fill a prescription product produced and the performance of traditional high strength china of the present invention and be compared as follows table:
As can be known from the above table, met and exceeded V class porcelain standard among the GB8411 according to fill a prescription every performance of the electrotechnical porcelain product produced of the present invention, particularly folding strength can reach 165～170Mpa (no glaze) or 221～231Mpa (glaze is arranged), can satisfy the requirement of 220～1000KV power transmission and transformation system fully, it is a kind of new formulation of producing superhigh intensity electric ceramic, replenish the blank of this series products of China, greatly promoted the development of electric utility.
