Electroceramics is mainly used in the transmission line of electricity of various electric pressures, transformer station, electric equipment in power system, and other some special industries such as power system of track traffic, conductor or the parts of different potentials is connected and plays insulation and supporting function.As for the cap and pin type suspension insulator of high-voltage line tension or pendency and long rod insulator, the solid core post insulator supported for substation bus bar or equipment, hollow insulator etc. for bushing shell for transformer, switchgear, capacitor or transformer, because relating to power industry, its mechanical performance, electric property, environmental resistance (cold and hot, anti-pollution, aging etc.) and stability etc. there is higher requirement.
Summary of the invention
It is an object of the invention to provide a kind of opal glaze for electric porcelain formula, the electrotechnical porcelain product stable performance that it prepares, it is adaptable to various power industries.
The object of the invention is achieved by the following technical programs:
A kind of opal glaze for electric porcelain formula is provided, is made up of each component of following weight fraction: porcelain stone 41～43 parts, zircon sand 17～21 parts, aluminium oxide 6～7 parts, Talcum 10～12 parts, build 4～8 parts of soil, calcium fluoride 3～5 parts, brium carbonate 5～6 parts, opacifiers 16～18 parts.
Preferably, described opal glaze for electric porcelain formula is made up of each component of following weight fraction: porcelain stone 42 parts, zircon sand 19 parts, aluminium oxide 6.5 parts, 11 parts of Talcum, builds 6 parts of soil, 4 parts of calcium fluoride, brium carbonate 5.5 parts, opacifiers 17 parts.
Preferably, described opacifiers is stibium oxide or titanium dioxide.
The preparation method of opal glaze of the present invention is: weigh raw material by formula, with material: water: ball=1:1:1.5 enters ball milling 8～10h, obtains glaze slip, and glaze slip fineness controls to tail over 0.03%～0.06% at 325 mesh sieves.
The using method of opal glaze of the present invention is: using leaching glaze mode is blank glazing, and glazed thickness controls 0.4～0.5mm, enters after klining becomes and obtains opal glaze electrotechnical porcelain product.
Compared with prior art, the method have the advantages that
The invention provides a kind of opal glaze for electric porcelain formula, the opal glaze glaze for electric porcelain pallor degree produced by this formula is more than 75, and rupture strength is more than 160 MPa, and cold-hot shock property is more than 240 DEG C, stable performance, it is adaptable to various power industries.
