Abstract

The invention discloses a purple sand ceramic product, which comprises a blank material and a glaze material, wherein the blank material comprises the following components in parts by weight: 32-38 parts of purple clay, 22-28 parts of bauxite clay, 10-20 parts of kaolin clay, 17-20 parts of attaclay, 12-14 parts of clinker and 2-5 parts of zinc oxide; and the glaze material comprises the following components in parts by weight: 38-40 parts of blank mud, 22-24 parts of clinker, 8-9 parts of frit, 22-24 parts of loess, 7-8 parts of iron red and 1-2 parts of water glass.

Description

Boccaro ceramic ware

Technical field

The present invention relates to Boccaro ceramic ware.

Background technology

Purple-clay product, claim again " boccaro ware ", " purple sand ceramics ", it is a kind of ceramic product made from special potter's clay, it can be made into ceramic commonly used in the various daily lifes, such as present popular electric soup cooker, electric cooker electrothermal dark-red pottery inner bag namely is, boccaro is a kind of irony clayey silt rock that contains, by hydromica and kaolin, quartz, scrap mica, the mineral compositions such as irony consist of, main chemical has silicon oxide, aluminum oxide, ferric oxide, calcium oxide, magnesium oxide, manganese oxide, potassium oxide, sodium oxides etc., color have the purple mud of multiple main one-tenth, three kinds in green mud and red soil, general term " purple clay ", because of iron content, the silicon amount is higher, fires the rear red-purple that is more, so claim " boccaro ", the processing performances such as it is good that it possesses plasticity-, and green strength is high, and dry shrinkage is little, purple clay is through the residual quartz that burnt till shape, the mica remains, mullite, red iron-stone, the phases such as dual pore, its crystallization phases is many, and glassy phase is few, makes purple-clay product have heat-shock resistance, ventilation property and higher physical strength, because it has been rich in various trace elements, the food that electrothermal dark-red pottery electric soup cooker and inner container of electric cooker stew has nourishing function to human body, and is widely used.The Boccaro ceramic ware of prior art ftractures easily.

Summary of the invention

For the shortcoming of prior art, the invention provides a kind of Boccaro ceramic ware.

For solving the problems of the technologies described above, the technical solution used in the present invention is:

A kind of Boccaro ceramic ware, it comprises blank and glaze, by weight percentage, blank comprises following component: 32～38 parts of Red Stone Wares, 22～28 parts of bauxite clays, 10～20 parts of kaolin, 17～20 parts of attaclaies, 12～14 parts in grog, 2～5 parts in zinc oxide; Glaze comprises following component: 38～40 parts in this base mud, 22～24 parts in grog, 8～9 parts of frits, 22～24 parts of loess, 7～8 parts of iron oxide reds, 1～2 part of water glass.

Blank mixing wet ball mill is to the 90-110 order; Glaze mixing wet ball mill is to the 300-380 order.

Compared with prior art, the invention has the beneficial effects as follows:

The present invention adopts above-mentioned raw materials proportioning raw material sources extensive, mainly extracting material within the border in Gaoan City, local Jiangxi Province can utilize, and the transportation cost that greatly economizes in raw materials is produced good product quality, cost is low, high efficiency is manufactured out the boccaro electric cooker inner bag, the food nutrition that the products such as electric soup cooker inner bag are cooked out, delicious, and the electric cooker of firing, electric soup cooker inner bag, thermostability are strong, and the product that the present invention produces is through 200～450 ℃ of range temperature thermal cyclings, and indices is all qualified.

Embodiment

The present invention is further illustrated below in conjunction with specific embodiment.

The content of aluminium sesquioxide is 20～45 parts in blank of the present invention, the glaze raw material, and silicon-dioxide contains the most 50-60 part.

Production process of the present invention is as follows:

Blank feed proportioning one ball milling one stirs a press filtration one old old mud one moulding of sieving, the demoulding one oven dry glaze; Glaze is prepared a ball milling one and is sieved;

Product is burnt till out in one glazing one of oven dry glaze.

Processing requirement: blank prepares former section by ratio requirement and put into the ball mill wet ball mill 10～14 hours, after the 90-110 mesh sieve, then puts into old about 10 days of the mud cake that the feed reservoir press filtration presses into water ratio about 20%, enters rear operation moulding again.

After glaze mixes by proportioning raw materials, put into the ball mill wet ball mill 70～100 hours, cross the 300-380 mesh sieve, wherein tripoly phosphate sodium STPP and other raw material add in the lump, or add first tripoly phosphate sodium STPP, other material of rear adding, and water glass blowing again after front about four hours of ball milling blowing adds ball milling.Water glass Ceramics process water glass, other each processing step are all produced by traditional purple sand ceramics production process process.
