Abstract
The invention discloses a multi-temperature sintering method for ceramic. The method comprises the steps: pre-sintering a ceramic blank body, and coating colour ceramic glaze or transparent glaze on the surface of the blank body; and carrying out multi-high-temperature sintering molding, wherein the percentage content of quartz sand in the ceramic blank body is less than 35%, the colour ceramic glaze or transparent glaze is pre-fired for about 10 hours at the temperature of 800-1250 DEG C; during the multi-high-temperature sintering molding, from high to low, sintering temperature spans over 20-100 DEG C each time. In the multi-temperature sintering method for the ceramic, the blank material with low quartz sand percentage content is used, the calcined colour ceramic glaze or transparent glaze is coated on the surface of the blank body, and multi-high-temperature sintering temperature is controlled, and finally, a decorative ceramic pattern with diverse color levels and bright gloss is formed, and the decorative ceramic pattern does not has the problems of foaming, decoloring and cracking.
Description
Technical field
The present invention relates to a kind of faience manufacture method, relate in particular to a kind of repeatedly temperature method for cooking that is used for pottery.
Background technology
Pottery is according to dissimilar, different performance requirement, and the different shapes of product, size and thickness etc., and manufacture method is also different, but passes through following technological process substantially:
1. idiosome pre-burning; 2, transfer the colouring of colored glaze or transparent; 3, idiosome surface finish; 4, step such as sinter molding, seeing also application number is 201010280934.7, denomination of invention is the patent documentation of " method of making cloisonne patterns on ceramic matrix ".
The pottery that aforesaid method is made is white basically, in order to form color on pottery, can add ceramic toner in pug, execute transparent glaze firing again after the biscuiting, make the multicolored entire body porcelain, the toner amount that this method is used is big, cost significantly improves, and can only realize monochrome decoration.
In order to form polychrome colored glaze pattern, two kinds of methods are arranged generally now: a kind of in porcelainization but also do not add coloured silk on the idiosome of glazing, this method is simple to operate, but because product moulding, pattern comes off easily, and the pattern level of decorating out in addition is abundant inadequately, and stereoscopic sensation is poor; Another kind method is directly to add coloured silk on idiosome, and this method is difficult to be grasped, and will carry out high temperature behind the coloured silk and burns till owing to add, and it generally is 1～3 time that present high temperature burns till number of times, and faience pattern color and luster is relatively poor.Abundant in order to form gradation, the faience pattern of bright in color must carry out more frequently that high temperature burns till, and it is many more to burn till number of times, and the difficult more control firing temperature and the coefficient of expansion easily bubble, decolour, ftracture after the burning of colored glaze district.
Summary of the invention
Technical problem to be solved by this invention provides a kind of repeatedly temperature method for cooking that is used for pottery, and it is abundant to form gradation, the faience pattern of bright in color, and can not bubble, decolour, ftracture.
The present invention solves the problems of the technologies described above the technical scheme that adopts to provide a kind of repeatedly temperature method for cooking that is used for pottery, comprise ceramic idiosome pre-burning, give colored glaze or transparent on the idiosome surface, the multiple high temp sinter molding, wherein, the quartz sand percentage composition is lower than 35% in the described ceramic idiosome; Described colored glaze or transparent carried out pre-burning about 10 hours under 800～1250 ℃; During the multiple high temp sinter molding, sintering temperature from high to low, each sintering temperature is crossed over 20～100 ℃.
The above-mentioned repeatedly temperature method for cooking that is used for pottery, wherein, when the high temperature sintering temperature below 800 ℃ the time, adopt backing plate to hold up the pottery bottom when firing.
The present invention contrasts prior art following beneficial effect: the repeatedly temperature method for cooking that is used for pottery provided by the invention, by selecting the low stock of quartz sand percentage composition for use and giving burnt colored glaze or transparent on the idiosome surface, and control multiple high temp firing temperature, it is abundant to form gradation, the faience pattern of bright in color, and can not bubble, decolour, ftracture.
Description of drawings
Fig. 1 is used for the decoration firing system of newly the painting method process flow sheet of special-shaped ceramics for the present invention.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is used for the decoration firing system of newly the painting method process flow sheet of special-shaped ceramics for the present invention.
See also Fig. 1, the repeatedly temperature method for cooking that is used for pottery provided by the invention in turn includes the following steps:
Step S1: select for use the quartz sand percentage composition to be lower than 35% the ceramic idiosome of anti-burning and carry out pre-burning, remove aqueous vapor and organic impurities in the carcass, increase the carcass surface strength, enter step S2;
Step S2: colored glaze or transparent were carried out pre-burning about 10 hours under 800～1250 ℃, giving colored glaze or transparent on the idiosome surface, the cracking decolouring enters step S3 in the time of can avoiding follow-up multiple high temp to burn till after colored glaze or the transparent pre-burning;
Step S3: multiple high temp sinter molding, sintering temperature from high to low, each sintering temperature is crossed over 20～100 ℃, preferably 50 ℃, enters step S4;
Step S4: when the high temperature sintering temperature below 800 ℃ the time, adopt backing plate to hold up the pottery bottom when firing, make the ventilation of pottery bottom, thereby guarantee that pottery is heated evenly, avoid because of multiple high temp sintering cracking.
The high temperature that adopts above-mentioned method for cooking can carry out as many as about 10 times burns till and avoids pottery or the decolouring of colored glaze cracking, thereby it is abundant to form gradation, the faience pattern of bright in color.
Though the present invention discloses as above with preferred embodiment; right its is not in order to qualification the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when can doing a little modification and perfect, so protection scope of the present invention is when with being as the criterion that claims were defined.
Claims (2)
