Abstract
The invention relates to a high-grade daily fine porcelain having high whiteness, high transmittancy, high heat stability, high strength and excellent appearance and internal quality, and a production technique thereof. The high-grade daily fine porcelain comprises a porcelain body, wherein the porcelain body comprises the following chemical components in percentage by weight: 80.0-93.0% of SiO2, 5.0-15.0% of Al2O3, 1.0-5.0% of CaO, 0.5-5.0% of MgO, 0.1-5.0% of K2O, 0.1-1.5% of Na2O, 0.1-1.5% of P2O5 and the balance of impurity. The porcelain body is prepared from the following raw materials in percentage by weight: 60.0-80.0% of quartz, 10.0-25.0% of clay and 5.0-20.0% of composite mineralizer. The invention well solves the problem of heat stability in the high-silicon material composition, and has the advantages of high whiteness, high transmittancy, high strength, high heat stability and other excellent properties. On the premise of ensuring the appearance quality and internal properties, the high-grade daily fine porcelain mainly prepared from the quartz has the advantages of low raw material cost, wide sources, obvious energy-saving consumption-reduction effect, and low production cost.
Description
Technical field
The present invention relates to a kind of high whiteness, high-transmittance, high thermal stability, high strength, outward appearance and inner quality be very excellent Pengyang china stone and production technique thereof all.
Background technology
Raw material is the basis of ceramic industry, as Pengyang china stone research, raw material select the especially most important thing.In the research of ceramic process, most raw material choose schemes are to walk the road of " selected " at present, and what have spares no expense, and national resources is greatly destroyed and wasted to " a thousand li chooses one ", have also improved production cost simultaneously.
Through consulting China from Tang, Song, unit, bright, clear porcelain making historical data, particularly Zhou Ren, Li Jiazhi, Zhang Fukang, the monograph of the famous ceramists such as Guo Yanyi, Li Guozhen so far, find to exist the problem of the thermostability of high silicon ingredient, quartzy (or SiO always
2) content is not high especially.
Summary of the invention
For the problems referred to above, the purpose of this invention is to provide a kind of Pengyang china stone, solved the thermal stability problems of high silicon ingredient, product has high whiteness, high-transmittance, high thermal stability, high strength, and cost is lower.
Pengyang china stone of the present invention comprises porcelain body, and the chemical weight percentage composition of porcelain body is: SiO
280.0～93.0%, Al
2O
35.0～15.0%, CaO1.0～5.0%, MgO0.5～5.0%, K
2O0.1～5.0%, Na
2O0.1～1.5%, P
2O
50.1～1.5%, surplus is impurity.
The optimum chemical weight percent of porcelain body consists of: SiO

2Etc. conventional raw mineral materials impurity.
The weight percent of the batching of porcelain body consists of: quartz 60.0～80.0%, clay 10.0～25.0% and composite mineralizer 5.0～20.0%.
The weight percent of the optimum proportion of porcelain body consists of: quartz 65.0～75.0%, clay 12.0～22.0% and composite mineralizer 8.0～18.0%.
Wherein: in the Pengyang china stone pug, quartzy particle diameter composition control is at 10～30 μ m, the appropriate design calcining system, although the porcelain body principal crystalline phase is alpha-quartz and cristobalite, porcelain body has still kept good physicochemical property.
Add composite mineralizer, make product become porcelain (1250 ℃) under lower temperature, on the one hand, amount of liquid phase is remained in the rational scope, the product physicochemical property is excellent; On the other hand, energy conservation and consumption reduction effects is remarkable.The weight percent of composite mineralizer consists of: rhombspar 30.0～55.0%, synthetic bone meal 10.0～25.0% and feldspar 25.0～55.0%, the porcelain body transparence is greater than 50%.
Pengyang china stone of the present invention can adopt the traditional ceramics production technique, various batchings are worked into the fineness of requirement after, by the proportioning batch mixing, through after screening out iron, through moulding, burn till and make porcelain body, directly as product.Also can be with the porcelain body glazing, porcelain body is made the fine porcelain of glaze smoothness through operations such as glazing, glaze firing, decorations.
The present invention adopts the abundant general ceramic raw material of China's reserves, the raw material that this institute adopts from treasuring and rationally utilize the angle of national mineral wealth, it is the raw material of the used suitability for industrialized production of general fine porcelain, commercialized supply, after raw material enters factory, no longer select, in order to avoid cause waste.Raw materials cost is lower by 40% than like product, and it is low by 20% to burn till cost, and the pug tooling cost is low by 25%, and energy conservation and consumption reduction effects is remarkable.
Pengyang china stone of the present invention, it forms and still belongs to K (Na)
2O-Al
2O
3-SiO
2The three component system system, still, quartzy (or SiO in the general prescription
2) content is 60.0～78.0%, text is invented quartzy (or SiO in the described porcelain body
2) content can be up to 90.0%, the present invention preferably resolves the thermal stability problems of high silicon ingredient.
After the present invention adopts the low temperature frit glaze glaze firing that obtains patent of invention, develop the Pengyang china stone of the premium propertiess such as high whiteness (greater than 80%), high-transmittance (greater than 50%), high strength (bending strength is greater than 140MPa), high thermal stability (be up to state standards, exceed 40 ℃ than Bone China).
Compared with prior art, the present invention has the following advantages:
(1) Pengyang china stone porcelain body of the present invention has very high quartz (or SiO
2) content, preferably resolve the thermal stability problems of high silicon ingredient.
(2) this Pengyang china stone has the premium propertiess such as high whiteness, high-transmittance, high strength, high thermal stability, porcelain exquisiteness.
(3) this product is under the prerequisite of guaranteeing excellent appearance quality and internal performance, and take quartz as body material, raw materials cost is low, and the source canal is wide, and energy conservation and consumption reduction effects is remarkable, and production cost is lower.
