Description

Polychrome ceramic bowl glaze and glazing technology

Technical field

The present invention relates to technical field of dinnerware, be specifically related to a kind of polychrome ceramic bowl glaze and glazing technology.

Background technology

Glass is divided into nonoxide glass and oxide glass by composition, and oxide glass is divided into silicate glass, borate glass, phosphate glass etc.Silicate glass refers to that basal component is Si0 ₂glass, be a kind of colourless transparent material, output is maximum, and purposes is the widest, cheap.Silica glass is the outstanding person in silicate glass, and the raw material manufacturing silica glass used is crystal, glass sand or white quartz sand, and its composition is highly purified Si0 ₂, its smelting temperature requires more than 1713 DEG C.

Silica glass has a series of special process based prediction model:

1. have excellent resistance to elevated temperatures, its fusing point is close with platinum;

2. coefficient of thermal expansion is minimum, only has 1/20 of simple glass;

3. have splendid spectral response curve, can through ultraviolet, infrared rays;

4. silica glass has fabulous acid resistance, insulativity.

Just because of these excellent in performance that silica glass has, and make it of many uses, be widely used in and produce mercuryvapour lamp, UV-lamp, infrared heater, acid-resistant container, thermally resistant container.

In ceramic bowl, add silica glass, the characteristic outside can improving, nearly one thousand years, in order to increase the slickness of goods, there is the high problem of lead tolerance in glaze, cannot fundamentally solve always.

Summary of the invention

It is low that technical problem to be solved by this invention is to provide a kind of cost, the polychrome ceramic bowl glaze that color is beautiful.

Technical problem to be solved by this invention realizes by the following technical solutions:

Described lubricating auxiliary agent is made up of the component of following weight part: lucium 2 parts, Graphite Powder 99 0.5 part, talcum powder 5 parts, carbon dust 0.2 part, phospho-wolframic acid 0.5 part;

In described lucium, by weight percentage, containing yttrium 65-85%, lanthanum and cerium mixture 15-35%.

Another object of the present invention is to provide a kind of glazing technology of polychrome ceramic bowl, comprises the steps:

1) prepared in proportion by glaze, put into ball mill and grind, fineness reaches 450-500 order, and sieving, it is stand-by to be mixed with glaze;

2) make ceramic bowl base substrate, and naturally dry under room temperature environment, prevent blank deformation;

3) blank sintering: first time enters klining knot, adopts reducing flame sintering, rises to temperature 950-1050 DEG C, firing time 16-18 hour;

4) be then incubated after 10-20 minute, naturally cooling, come out of the stove;

5) with the glaze prepared in the even glazing of billet surface;

6) blank sintering after glazing: second time enters klining knot, adopts reducing flame sintering, fires 20 hours under 140 DEG C of environment, after soaking time 10-20 minute, naturally cooling, to come out of the stove.

The invention has the beneficial effects as follows:

1) lead material is removed by the present invention, adds quartz and lubricating auxiliary agent etc., adds surface strength and the slickness of glaze colours, good hand touch;

2) reduce double sintering temperature simultaneously, extend sintering time, make the ceramic bowl never peeling of preparation, be convenient to persistence;

3) increase the composition such as shell, bloodstone, make the bowl surface fired have spot, color is attractive in appearance.
