Background technology
Glaze is uniform continuously, the slick glass state material of skim that covers the ceramic surface.Glaze for electric porcelain then is the level and smooth material of porcelain insulator surface, and the about 0.2-0.3mm of the thickness of this glass coating points out the microstructure analysis of glaze, in the glaze of successive, vitreous state, also has a small amount of tiny crystal grain and bubble.
Physical strength is the most important performance that electric porcelain production is pursued always, because electroporcelain material when having HS, under the condition of equal voltage range, can improve the rate of utilization of material, reduces cost.Traditional electroceramics palm fibre glaze, after the glazing, to improve electroceramics mechanical, electrical, the thermal property effect is bad, the flexural strength of raising porcelain that especially can not be bigger.
Along with the development of electricity market, the expansion of electrotechnical porcelain product range of application, according to different clients' actual demand, the electrotechnical porcelain product kind is variation also, comprises that the outward appearance, color etc. of porcelain spare all have requirement.The color of electrotechnical porcelain product is to determine by covering its surperficial color, adopts brown glaze to be brown, adopts white glaze to be white in color, and brown glaze is that electrotechnical porcelain product is used more coloured glaze.And existing brown glaze, the colour generation weak effect, irregular colour is even, aberration even macroscopic irregularity such as blackspot occurs.
Summary of the invention
Be to solve the deficiency of prior art, the object of the present invention is to provide porcelain good mechanical property after a kind of glazing, surperficial colour generation is effective, the novel high-strength electroceramics palm fibre glaze formula of defectives such as the even no color differnece of distribution of color.
For achieving the above object, the present invention realizes through following technical scheme:
A kind of novel high-strength electroceramics palm fibre glaze formula is characterized in that, comprises that the parts by weight of following component and each component are:
Potassium felspar sand 23-27 part;
Quartzy 25-29 part;
Green grass mountain range 8-13 part;
Water-washed kaoline 6-9 part;
Planetesimal kaolin 5-8 part;
Talcum 4-7 part;
Wingdale 2-6 part;
Zuoyun soil 1-4 part;
Calcined bauxite in powder 1-3 part;
Toner 6-10 part.
Further, described toner comprises that the parts by weight of following component and each component are respectively:
Red stone 15-30 part;
Chromic oxide 15-30 part;
Manganese oxide 40-60 part.
The invention has the beneficial effects as follows: electroceramics palm fibre glaze porcelain good mechanical property after the electroceramics glazing of formulation of the present invention; Macroscopic irregularitys such as intensity is high, the glaze colour generation is effective, distribution of color is even, no color differnece, blackspot; Fill up the blank of this type of glaze for electric porcelain, be worthy of popularization.

The preparation technology of the foregoing description 1-3 is identical with the preparation method of traditional electroceramics palm fibre glaze, all adopts wet ball grinding technology.
In the preparation process, the chemical ingredients and the physicals of electroceramics palm fibre glaze of the present invention are following:
Table 1: the chemical analysis composition (%) of brown glaze:
| Si 2O | Fe 2O 3 | Al 2O 3 | CaO | MgO | K 2O | Na 2O | ?IL | Cr 2O 3 | MnO 2 |
| 60-65 | 2-3 | 13-16 | 4-6 | 2-4 | 2-4 | 0.2-0.6 | 4-7 | 1-3 | 1-3 |
Table 2: the physicals of brown glaze:
Table 3: performance after the burning of brown glaze:
Compared with prior art, advantage of the present invention is: owing to added the physical strength that toner can reduce glaze, in prescription, increased the calcined bauxite in powder of certain component for this reason.Zuoyun soil and water-washed kaoline all have the effect that strengthens the glaze physical strength in the prescription simultaneously.Can form good middle layer after the glazing, the flexural strength that increases substantially porcelain is more than 35%, and each item performance index all meet the demands.The red stone that in the prescription of electroceramics palm fibre glaze, is widely used is reached common understanding in industry as tinting material.Fe
2O
3Fusing point be 1560 ° of c, to brown, it has very big unstable to color by red, Fe during high temperature
2O
3Change the tendency of FeO at a low price.Along with the difference that furnace atmosphere and oxygen are pressed, Fe
2O
3Also can come and go with the ratio of FeO, thereby make glaze be different colours.Yet owing to introduce Fe in the brown glaze
2O
3Tinting material after, reduced the arc resistance of glaze greatly, therefore allocating Fe into
2O
3The time also allocate certain MnO accordingly into
2And Cr
2O
7Can increase its electric arc property.Glaze for electric porcelain is a kind of very complicated silicate compound, consider the physicochemical property and the stability of all cpds.The present invention has overcome above-mentioned defective, and the glaze colour generation is effective, and distribution of color is even, and defectives such as no color differnece are filled up the blank of this type of glaze for electric porcelain, are worthy of popularization.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
