Abstract
The invention provides a billet formula for producing stoneware for daily use by utilizing sericite chinastone instead of feldspar, quartz and part of kaolin, belonging to the technical field of ceramics for daily use. The stoneware for daily use is produced by using the billet formed by 50-70% by mass of chinastone, 30-50% by mass of refractory clay and a small quantity of mineralizers. The problems of resource shortage caused by using plenty of kaolin, china clay and feldspar in traditional formulas, high cost and the like are solved by adopting the billet formula. The billet formula takes full advantage of chinastone which is abundant, has stable quality and is low in cost, is low in ingredient costs, has good usability, can be quickly fired at low temperature, saves energy, has obvious economic and social benefits and can be widely popularized and applied in the stoneware industry.
Description
Technical field
the present invention relates to a kind of sericite matter Household stoneware low temperature blank formulation, belong to domestic ceramics technical field.
Background technology
shi porcelain, be the class ceramic between pottery and porcelain, conventionally also claim stoneware.For the production of ceramics ware for daily use meal tea set and craft artistic pottery and porcelain.
up to the present, Household stoneware blank mainly contains two large types: a class is (feldspar-quartz-kaolin) type taking feldspar as flux, and Equations of The Second Kind is (albite-quartz-kaolin) type taking albite as flux.Two kinds of blanks respectively have its relative merits, and first kind firing temperature is higher, and fuel expends more; Equations of The Second Kind firing range is not wide, and thermostability is poor, and product strength is not high.
shi porcelain products are all the fashion abroad, on international goods is easy, exceeded porcelain, occupy very large proportion, and domestic production in a large number exported for two more than ten years.
because Shi porcelain products are more thick and heavy, add all the year round and to produce, material consumption is huge, mine day by day exhausted, in short supply, price rise, cost increase.Finding alternative materials is the pressing problem that current Shi porcelain industry faces.
sericite china stone (abbreviation porcelain stone) is a kind of traditional porcelain making raw material, and chemical composition is compared with feldspar.K

content is higher, thereby melt temperature is high compared with feldspar.In the prior art, generally prepare burden to produce porcelain with porcelain stone and kaolin.It is (sericite-quartz-kaolin) system porcelain using the sericite class mineral in porcelain stone as flux, is called for short sericite china.
porcelain stone uses as porcelain making raw material, has very long history.The place of production is a lot, and reserves are abundant.Ingredient stability is also its a large characteristic.
but using porcelain stone as the main raw material of making Shi porcelain, especially for the blank of easy fired, have not been reported and example.
object of the present invention, will develop a kind of low temperature Shi porcelain formula that can widely apply porcelain stone exactly, widens Shi porcelain raw material sources, reduces production costs.
Summary of the invention
the technical problem to be solved in the present invention, is the weakness for prior art, provides one can adapt to low temperature and burns till fast, thermally-stabilised good, intensity is high, the Shi porcelain blank formulation that simultaneously can match with existing versicolor glaze.
address the above problem and take following technical scheme, for the AI in porcelain stone

lower, add fireclay, for the higher sepiolite that adds of firing temperature,
technical essential of the present invention is:
1, replace the whole feldspars in existing formula with porcelain stone, all quartz and part kaolin, with the kaolin of fireclay replacement remainder.Manufacture Household stoneware using sepiolite as the blank that mineralizer was formed,
2, suitable proportion and the allowed band of each component in experimental study formula.
sepiolite is a kind of magnesia fireproof clay, in history for making saggar.In blank, add a small amount of sepiolite, can reduce blank firing temperature, form at a lower temperature liquid phase, accelerate the generation of mullite, improve the physical strength of goods.Can also form a part of trichroite, reduce the coefficient of expansion of blank, promote the combination of base and glaze, improve the emergency heat and cooling property resistance sex change energy of goods simultaneously.Improve thermostability.
the kind of mineralizer can be sepiolite type attaclay, talcum and rhombspar.The selection of kind can be according to the source of goods and cost etc. because usually determining.
while adopting sericite matter Shi porcelain low temperature blank formulation provided by the invention to produce Shi porcelain, production technique is identical with existing production technique.
advantage of the present invention is:
1, utilize fully resource, alleviated Shi porcelain raw material supply anxiety, contradiction that cost is very high.(
blank cost 50-60%)
2, overcome the weakness of existing formula, can burn till fast, save energy,
3, simple, stable, the good operation performance of formula, conforming product rate are high,
4, product Heat stability is good, intensity is high,
embodiment.
by repeatedly repeatedly testing and draw, the scope of following each component is applicable to making low temperature Household stoneware,
