Description
Technical field
The present invention relates to the manufacturing technology field of porcelain, be specifically related to a kind of green ceramic goods and production method thereof.
Background technology
Porcelain is to be fired by porcelain stone, Kaolin, quartz, mullite etc. to form, and outer top application has the sundries of nature of glass glaze or colored drawing.The shaping of porcelain will be by firing through high temperature (about 1280 DEG C ~ 1400 DEG C) in kiln, and the glaze colours on porcelain surface is understood the difference because of temperature thus various chemical change is occurred.The porcelain tire of sintering normally only containing 3% less than ferrum element, and waterproof, the cost the cheapest because of it and the wear-resisting fluid-tight characteristic common people the most all over the world are used.
The predecessor of porcelain is original celadon, and it is to the product of porcelain transition stage by pottery, and celadon is the treasure of Han nationality's ceramic sintering process, executes the porcelain of cyan glaze as a kind of surface.Before firing, execute last layer starved glaze on the surface of base, containing a certain amount of ferrum oxide in the formation of celadon tone, mainly tire glaze, in reducing flame atmosphere caused by roasting.But this celadon is impure because of iron content, and reducing atmosphere is inadequate, tone presents uneven yellow or yellowish-brown rather than simple green, therefore adopts the green ceramic goods produced in this way and there is cost of manufacture height, the factitious problem of tone.
Summary of the invention
The invention is intended to provide a kind of green ceramic goods and production method thereof, green ceramic goods can only be produced by applying cyan glaze solving prior art, and occur that cost of manufacture is high, the factitious problem of tone.
A kind of green ceramic goods in this programme, raw material includes SiO, Al2O₃、Fe2O3、CaO、MgO、K2O、Na2O and water, the weight fraction between each composition is SiO, the Al of 8 ~ 11% of 50 ~ 55%2O₃, the Fe of 3 ~ 5%2O3, the CaO of 11 ~ 13%, the MgO of 2 ~ 3%, the K of 1 ~ 2%2O, the Na of 0.5 ~ 1%2O, surplus is water.
Raw material is configured by mentioned component, it is configured with the most special chemical composition and mineralogical composition, compound rich in abundant Al, Fe, Ca, Mg and K, present multiple green with its pottery part fired, and uniform hue is natural, it is not necessary to glazing, it is not added with pigment, and have distinctive transmutation phenomenon, it is the special natural green ceramic of a kind of processing performance, has exploitation prospect widely.
The production method of a kind of green ceramic goods, described step includes: a, pretreatment: described raw material process be exposed to the sun, air slaking process, and obtain potter's clay；
B, attrition grinding: repeatedly smashed by the potter's clay pulverizer in step a, add water after screening stirring, and in ball mill, ball milling makes its granularity reach 300 ~ 900 mesh, precipitation, is bled off by clear water, hangs slurry, obtains mud；
C, pugging stirring: by the mud dry in the sun in step b, water content control, 15 ~ 20%, is mixed thoroughly in pug mill, obtains mud of making pottery；
D, fermentation: the pottery mud thin film parcel fermentation after mixing thoroughly in step c, fully seal；
E, moulding: the pottery mud that ferments in step d is moulding, and manual kneading or machine are fabricated to semi-finished product；
F, firing: the semi-finished product made are put in kiln calcining, and temperature is gradually increasing, and end temperature controls at 1050 DEG C ~ 1300 DEG C, firing total time is 10 ~ 12h, and flame-out after having fired, in kiln, natural cooling cooling, obtains green ceramic goods.
Beneficial effects of the present invention: the present invention, with the potter's clay after configuration as raw material, is not required to add any dispensing, can be directly used as raw material and use, and processes technique and burning process by specific, just can produce cellar for storing things and become, produce and have glassy lustre, the product of natural glaze colours；The present invention with existing need to apply glaze just fertile green ceramic product process compared with, there is the advantage that cost of manufacture is low, product shade natural and can keep ceramic pure natural characteristic.
Further, duration of being exposed to the sun in described step a is 1 ~ 36 month.By raw material is exposed to the sun in the wild, air slaking, make potter's clay crisp fluffy, beneficially attrition grinding.
Further, in described step b, the ratio of potter's clay and water is 1:4 ~ 1:2.Potter's clay draws for verifying through test of many times with the ratio of water, when the ratio of potter's clay with water is less than 1:4, and now the content of water is many, and slip is excessive rarefied, can cause the direct shock of abrasive media, increase the consume of abrasive body, and machine utilization amount is big；When the ratio of potter's clay with water is more than 1/2, and now the content of potter's clay is many, slip excessively thickness, and the slip of thickness has delay effect to abrasive media so that it is velocity of rotation slows down, and grinding efficiency reduces, and after ball milling, granularity is big, and best proportion is 1:3.
Further, the fermentation time in described step d is 4 ~ 5 months.By the sealing and fermenting of 4 ~ 5 months, make pottery mud generation chemical reaction, make the pottery mud after fermentation more soft, fine and smooth, it is simple to ceramic makes and molding.
Further, in described step f, kiln temperature control is: kiln temperature rises to 1050 ~ 1300 DEG C from 0 DEG C, wherein, the heating-up time of 0 ~ 300 DEG C is 3 ~ 4h, 300 ~ 700 DEG C of heating-up times are 2 ~ 3h, 700 ~ 900 DEG C of heating-up times are 1 ~ 1.5h, and 900 ~ 1050 DEG C of heating-up times are 0.2 ~ 0.4h, and temperature keeps 1050 ~ 1300 DEG C afterwards.Through the ceramic that above-mentioned technique is fired, temperature raises in proper order, and the inner and outer wall making goods is smooth unanimously, artware free from flaw, and glossiness keeps consistent with color.
