Description

Boccaro ceramic ware

Technical field: the present invention relates to a kind of Boccaro ceramic ware, particularly relate to a kind of boccaro soup pot, meal pot ceramic liner goods.

Background technology: boccaro goods, claim again " boccaro ware ", " boccaro pottery ", 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, as present popular electric soup cooker, electric cooker electrothermal dark-red pottery inner bag promptly is, boccaro is a kind of irony clayey silt rock that contains, by hydromica and kaolin, quartzy, scrap mica, mineral compositions such as irony constitute, main chemical has silicon oxide, aluminum oxide, ferric oxide, calcium oxide, magnesium oxide, manganese oxide, potassium oxide, sodium oxide etc., color has the purple mud of multiple main one-tenth, three kinds in green mud and red soil, general term " purple clay " is because of iron content, the silicon amount is higher, fire the back and be red-purple more, so claim " boccaro ", it is good that it possesses plasticity-, the green strength height, processing performances such as dry shrinkage is little, purple clay is through burnt till shape residual quartz, mica remains, mullite, red iron-stone, thing phases such as dual pore, its crystallization phases is many, and glassy phase is few, make the boccaro goods have heat-shock resistance, ventilation property and higher physical strength are because of it has been rich in various trace elements, the food that electrothermal dark-red pottery electric soup cooker and inner container of electric cooker are stewed system has nourishing function to human body, and be widely used, a kind of product as Chinese patent 02112084.6 " making method of ceramic slow stewing pan " promptly is, but it highlights the making method of sand ceramic slow stewing pan.

Summary of the invention: purpose of the present invention will provide a kind of Boccaro ceramic ware exactly.

Boccaro ceramic ware of the present invention, it is manufactured raw material and comprises blank and glaze, by weight percentage,

The content of aluminium sesquioxide is 20-49% in blank of the present invention, the glaze raw material, and dioxide-containing silica is 50-65%.

Production process of the present invention is as follows:

Blank feed proportioning → ball milling → stirring sieves → press filtration → old old mud → moulding, the demoulding → oven dry glaze

Glaze preparation → ball milling → sieve-↑ glazing → burn till out product.

Processing requirement: blank prepares raw material by ratio requirement and put into the ball mill wet ball mill 10～14 hours, after 90～120 mesh sieves, puts into old about 10 days of the mud cake that the feed reservoir press filtration presses into water ratio about 20% then, enters back operation moulding again.

After glaze mixes by proportioning raw materials, put into the ball mill wet ball mill 70～100 hours, cross 320～400 mesh sieves, wherein tripoly phosphate sodium STPP and other raw material add in the lump, or elder generation adds tripoly phosphate sodium STPP, the back adds other material, and water glass blowing again after the ball milling blowing added ball milling in preceding about four hours.Water glass is selected ceramic industry water glass for use, and other each processing step is all produced by traditional boccaro pottery production process process.

Grog described in claims of the present invention and the specification sheets is this product grog.

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 economizes in raw materials is greatly produced good product quality, cost is low, high efficiency is manufactured out the boccaro inner container of electric cooker, the food nutrition that 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 every index is all qualified.

This product rapid heat cycle examination method is: this product that will prepare is put into experiment and is heated to 200～450 ℃ with electrothermal oven and configures detected temperatures by product design demand temperature, after reaching design temperature, take out rapidly and put into 20 ℃ water, do not ftracture to qualified with the electrothermal dark-red pottery product.Product among the embodiment all adopts present method to detect.
