Embodiment

[0012] Examples: (1) First take vermiculite and calcinate it at 1200°C for 1 hour, then crush it through a 20-mesh sieve to obtain calcined vermiculite powder;

[0013] (2) Take 26 parts by weight of halloysite, 15 parts by weight of sericite, 15 parts by weight of perilla pyroxene, 9 parts by weight of sodium tripolyphosphate, 9 parts by weight of calcined vermiculite powder, 4 parts by weight of boronite, After mixing 3 parts by weight of puff stone and adding water ball mill, passing through a 325-mesh sieve, and then according to the traditional process, dehydration, mud pressing, aging, mud refining, and grouting are used to obtain a pot-shaped green body, and the green body is glazed;

[0014] (3) Put the green body in the kiln, first heat up to 210°C within 20 minutes and burn for 70 minutes, then heat up to 1160°C for 7 hours, and then cool down to 820°C at a rate of 10°C every 5 minutes Finally, keep warm for another 70 minutes, and finally cool naturally to 30°C to m...

Abstract

The invention discloses petuntse used for preparing an exquisite ceramic cooker and a method for preparing the exquisite ceramic cooker from the petuntse. The petuntse comprises the following components, 25 to 27 parts by weight of halloysite, 14 to 16 parts by weight of sericite, 14 to 16 parts by weight of hypersthene, 8 to 10 parts by weight of sodium tripolyphosphate, 8 to 10 parts by weight of calcined vermiculite powder, 4 to 5 parts of howlite and 2 to 3 parts by weight of meerschaum; the calcined vermiculite powder is manufactured in the way that vermiculite is calcined for 1 to 1.2 hours at 1200 DEG C to 1220 DEG C, and is smashed and sieved by a 20-mesh sieve. The petuntse provided by the invention has the advantages that the firing temperature is lowered greatly, the firing range is broadened, the effects of environment friendliness and energy conservation are achieved, and the manufacturing cost is reduced; the manufactured exquisite ceramic cooker can not crack under the condition of heat exchange at 600 DEG C to 20 DEG C, and the application range of the product is wide.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a porcelain clay for preparing a fine ceramic cooker and a method for making a fine ceramic cooker from it. Background technique [0002] According to the light industry standard of the People's Republic of China "Fine Ceramic Cooker (QBT 2580-2002)", fine ceramic cooker refers to those with high heat resistance and thermal stability with a temperature difference of not less than 380°C, which are used for heating and preparing Ceramic cooking utensils for food. Due to the requirements of use, the firing temperature of fine ceramic cookers generally needs to reach 1280-1320°C. The high-temperature firing means high energy consumption and high costs for manufacturers. Contents of the invention [0003] In order to solve the above problems, the present invention provides a porcelain clay for preparing fine ceramic cookers and a method for making fine ceramic cookers with it. [0004] Por...
