3,4 two methods are combined into production mat glaze.It adds in without photo etching calcium oxide, barium carbonate, zinc oxide, magnesium carbonate, talcum etc.
Calcium mat glaze, barium mat glaze, zinc mat glaze, magnesium mat glaze can be respectively obtained.
Above several mat glazes respectively have advantage and disadvantage, and calcium mat glaze is wider to the adaptability of color glaze, the performance of acid resistance compared with
By force, to cause lead that can not be dissolved out from these glaze, but glaze paint slightly shows coarse, can with the naked eye tell thickness crystalline substance
Flower, barium mat glaze expensive raw material price, and barium carbonate is toxic.Magnesium mat glaze is relatively narrow to the adaptability of color glaze, but glaze paint it is smooth,
Exquisiteness, cost of material are low.Zinc mat glaze, crystal grain is smaller, and glaze paint is smooth, fine and smooth.According to the additive property of surface tension, magnesium mat glaze
The surface tension of melt is greater than calcium mat glaze, barium mat glaze, the surface tension of zinc mat glaze, and when the surface tension of glaze melt
It when larger, can close the open pore that gas escapes, it is scarce plain so as to reduce pin hole and orange peel glaze etc., it is put down so as to reach product glaze paint
It is whole, in wax-like gloss.
The present invention, without photo etching, adds a small amount of zinc oxide based on magnesia and calcium oxide, adjusts raw material composition and ratio
Ensure high temperature viscosity and surface tension, to reach raising glaze quality, reduce production cost, product physicochemical property reaches country
The purpose of standard.
Glaze is divided into low temperature glaze, intermediate glaze and high-temperature glaze by the temperature of firing.
The temperature that low temperature glaze is fired is relatively low, below 1200 DEG C, easily makes more glaze unfused, causes glaze paint coarse,
There is gap, it is rough, influence beautiful and performance.The temperature that high-temperature glaze is fired is higher, at 1300 DEG C or more, be easy to cause glaze
Expect abundant penetration, milkiness area scope is small, and gloss area scope is big, loses no light effect, and energy consumption is big, is not suitable for large-scale production.
Therefore, the present invention is fired using medium temperature, and temperature is 1250-1280 DEG C, and obtained mat glaze is preferable without light effect, and glaze paint light
Sliding, fine and smooth, energy consumption is low.
The thixotropy of glaze slip is reduced by adding in calcining zinc oxide in the present invention, improves the operating characteristics of glaze slip so that
The glazed thickness of green body is between 0.2-0.4mm after glazing.
It can prevent glaze from bringing impurity in ball mill process is gone out glaze slip sieving, as ball-milling medium is (i.e. in ball mill
Ballstone and ball milling liner) small broken particle, the impurity particle that ball mill discharging mouth is brought etc., general 120 mesh sieve can screen out these
Impurity.
Thixotropy mainly does contrast test in terms of Production of Ceramics by Ford cup, mainly passes through practice test, i.e. glaze
Material is handy in use, and does not generate such as excess glaze, glaze muscle glaze planar defect.Substantially by glazing operative employee or production line
Quality Inspector is adjusted by rule of thumb.
