Abstract
The invention discloses daily rigid fine china and a producing method thereof. The daily rigid fine china is formed by firing a perform body and glaze, wherein the perform body is prepared from the following raw materials in percentage by weight: 13-16% of quartz, 5-8% of feldspar, 13-16% of greensand, 17-20% of Longyan soil, 1-4% of camwood knags, 18-21% of mature sandstone, 1-4% of montmorillonite, 5-8% of Tangxian soil and 16-19% talcum powder; the glaze is prepared from main materials and an additive, wherein the main materials comprise the following components in percentage by weight: 95-98% of clinker and 2-5% of Soochow soil. In the invention, the blank glaze adaptability is effectively improved by optimizing the formula of the glaze; and the appearance quality of the produced fine china is obviously improved, especially the appearance quality of the glaze surface achieves the level of high-grade bone china, and the rigidity and wear resistance of the glaze surface are higher than those of the bone china; the defects that the glaze surface of the bone chine is soft, easy to etch, and not suitable for cleaning of a bowl washer and the like are overcome, thus the use range of the daily fine china is extended.
Description
Technical field
The present invention relates to a kind of pottery and working method thereof, especially a kind of hard daily-use fine and working method thereof.
Background technology
Domestic common daily ceramic whiteware uses raw glaze mostly at present, and glaze quality is generally not high, and price is also just low, adds all the more many factors such as scarcity and environmental protection of China's Ceramic Material resource, and the international market demand amount is more and more littler.Adjust the product mix, eliminate low grade products, develop the inexorable trend that the high-grade daily-use fine with high added value has become technical development.Present high-grade daily-use fine mainly is the sclerotin porcelain, and the sclerotin porcelain is fine and smooth with glaze, and advantages such as good transmittance enjoy people to like; But there are some unsatisfactory shortcomings in the sclerotin porcelain because of its distinctive prescription and production technique, the one, and the bad plasticity of pug; Can not produce the product of complicated type; The 2nd, the thermostability of product is relatively poor, and the 3rd, hardness of glaze surface is poor, and the 4th, the adding of bone black has improved product cost greatly.
Summary of the invention
The technical problem that the present invention will solve provides that a kind of hardness of glaze surface is high, glossiness is good, the hard daily-use fine of Heat stability is good; The present invention also provides a kind of working method of hard daily-use fine.
For solving the problems of the technologies described above, it is fired the present invention by blank and glaze and forms, and described blank is processed by following weight percentages: quartzy 13～16%; Feldspar 5～8%, greensand 13～16%, Longyan clay 17～20%; Camwood knag 1～4%; Ripe sand 18～21%, polynite 1～4%, Tangxian County soil 5～8% and talcum powder 16～19%;
Described glaze major ingredient and additive are processed, and the weight percent of said major ingredient is: frit 95～98%, Suzhou soil 2～5%.
Preferred additives of the present invention is the Xylo-Mucine of major ingredient weight 0.05～0.1% and 0.03～0.07% Sodium hexametaphosphate 99.
The preferred frit of the present invention is made up of following weight percentages: quartz 15～20%, and feldspar 35～45%, Wingdale 15～25% burns talcum 5～15%, zinc oxide 4～10%, barium carbonate 3～8%, boric acid 5～10%, saltpetre 2～10%.
The pH value of the preferred glaze slip of the present invention is 7.5～9.5.
The inventive method adopts above-mentioned proportioning raw materials, and this method steps is: a. prepares blank mud: the raw material of blank is dropped into by proportioning add water in the ball mill and grind, sieve then, deironing, obtain blank mud;
B. prepare the mud section: after blank mud was processed mud cake with the pressure filter press filtration, use was stirred the mud machine and is carried out vacuum refining mud, obtains blank mud section;
C. prepare frit: the raw material of frit is mixed by proportioning, in 1400 ℃～1450 ℃ calcars, found, shrend then obtains frit;
D. prepare glaze slip: the raw material of glaze is dropped into by proportioning add water in the ball mill and grind, sieve then, deironing, obtain glaze slip;
E. the roll forming of the resultant blank mud of roll forming: step b section is a base substrate, drying;
F. biscuiting: described base substrate carries out biscuiting, obtains mold; The biscuiting temperature is 1280 ℃～1300 ℃, and firing period is 18～20 hours;
G. glazing: glaze slip glazing on mold of adopting steps d to obtain;
H. glaze firing: the mold after the glazing carries out glaze firing, can obtain described fine porcelain; Wherein, temperature of glaze firing is 1150 ℃～1200 ℃, and firing period is 15～17 hours.
Feed ratio when grinding among the said step a of the inventive method is: raw material: ball: water=1:1.8～2.1:0.8～1.1; Grind the back and cross 250～300 mesh sieves.
The water ratio of the blank mud section that obtains among the said step b of the inventive method is 21～24wt%.
8, the working method of hard daily-use fine according to claim 5 is characterized in that: the feed ratio when grinding in the said steps d is: raw material: ball: water=1:1.6～1.8:0.4～0.5; Being ground to fineness is: 10000-hole sieve is surplus to be not more than 0.1%; Grind the back and cross 300 mesh sieves.
It is 21～24wt% that blank mud section among the said step e of the inventive method is dried to water ratio at 40 ℃～60 ℃.
Glazing proportion in the said step g of the inventive method is 1.70～1.80g/cm
3, the glaze layer thickness is 0.15～0.3mm.
Adopt the beneficial effect that technique scheme produced to be: the present invention is through optimizing the base glaze formula; Effectively improved glaze fit; The fine porcelain visual appearance of producing all is significantly increased; Especially the glaze visual appearance has reached the level of high-grade bone china, and hardness of glaze surface and wear resistance are higher than the sclerotin porcelain; It is thin-skinned to have overcome sclerotin enamel, and not anti-delineation is not suitable for shortcomings such as dishwasher cleaning; Thereby expanded the use range of daily-use fine.
Warm fritted glaze technology during product of the present invention and method are used, thus quality product effectively promoted.
The all far ultra sclerotin porcelain in the physicochemical property aspect of product of the present invention, the unit product price only is about 2/3rds of a sclerotin porcelain, has cost performance height, characteristics that production cost is low.
