Background technology
Bone China is called for short china, formal name used at school bone china, that to take bone carbon, clay, feldspar and the quartz of animal be main raw material, through high temperature biscuiting and low temperature sinter, fire a kind of porcelain forming for twice, according to the set china standard of Britain, contain more than 30% from the tricalcium phosphate in animal skeleton, and finished product has light transmission, side must become china, and the standard of the U.S. is minimum will reaching more than 25%.
Bone China appearance looks elegant, porcelain exquisiteness is penetrating, and structured shape degree is high, elegant attractive in appearance, and the moist light of glaze can be ornamental strong, and flower face is colourful, and porcelain physical strength is high, and impact resistance is good, can make thin tire product.Bone China begins to originate in Britain, is Britain imperial family and noble's special-purpose porcelain for a long time, is the high-grade porcelain kind of generally acknowledging in the world at present, it has practical and artistic dual value concurrently, being right and status symbol, is also the embodiment of life grade, is known as " king of porcelain ".
Bone China good decorative property, is the natural characteristics that other porcelain cannot be comparable, and high-grade bone china faience is that the trailing that is posted in-glaze decoration marble paper on white quality china goods is made at present, and its technological principle is that colorant is molten in glaze layer in roast process; Chinese red, the yellow low temperature color glaze of emperor are decorated and have been widely used in sclerotin porcelain, and decoration technology complexity is various.Due to technological reason, the reason such as low-temp exists hardness of glaze surface low, and anti-pollution characteristic is poor, acid-alkali-corrosive-resisting ability, is never being used matt glaze aspect china product decoration.
Summary of the invention
In order to realize the making of above-mentioned sclerotin matt glaze, a kind of method that the invention provides sclerotin matt glaze and make Bone China product of this glaze.
For achieving the above object, the present invention by the following technical solutions:
A sclerotin matt glaze, comprises following component and weight proportion umber: 100 parts of frits, 3~8 parts of clays, 2~12 parts of wollastonites, 3~6 parts, aluminum oxide, 6~15 parts, zinc oxide, 6 parts, stannic oxide; Wherein, described frit comprises following component and weight proportion umber: quartzy 16~24 parts, and 28~38 parts of potassium felspar sands, 12~18 parts of boraxs, 0~7 part of boric acid, 0~5 part of Strontium carbonate powder, 0~8 part of Quilonum Retard, 0~10 part, zinc oxide, 0~3 part, talcum, calcite 0~12,0~0.5 part of zirconium silicate.
The method that use sclerotin matt glaze claimed in claim 1 is made Bone China product, method steps is:
S1: the raw material stirring in described frit formula is even, at 1300-1330 ℃ of temperature, melt, make frit standby;
S2: get the frit obtaining in S1, the raw material in described glaze formula is entered to mill, take total mass as benchmark, adding mass percent is the water of 30-32%, grinds 48-55 hour, fineness 325 mesh sieve residue≤0.1% are crossed 200-250 mesh sieve, standby;
S3: the glaze obtaining in S2 glaze spraying in bique is dried, and glaze layer thickness scope is 6 grams/100 cm
2, entering kiln oxidation and fire, firing condition is: normal temperature heating, speed with 3 ~ 5 ℃/min is warmed up to 360 ℃, and then the speed with 2 ~ 4 ℃/min is warmed up to 900 ℃, then is warmed up to 1150 ~ 1180 ℃ with the speed of 1 ~ 2 ℃/min, insulation 20 ~ 30min, naturally cools to room temperature.Can burn till with common china light glaze, firing process is simple simultaneously.
Borax is in sclerotin matte glaze product, and mainly with boron oxide generation effect, in glaze, zinc oxide, wollastonite play a decisive role to separating out crystallite, and silica alumina ratio is controlled at the scope of 10:1 and boron oxide 8% left and right, is conducive to crystallization; Stannic oxide has good milkiness effect, is conducive to crystallization simultaneously, improves porcelain glaze whiteness, and the difference of wollastonite and zinc oxide is arranged in pairs or groups, and can adjust the glaze of different maturing temperatures.Zinc oxide, boron oxide, aluminum oxide, stannic oxide acting in conjunction, be both conducive to crystallization, prevents that again crystal from growing up.
Compared with prior art, the present invention has following beneficial effect: glaze is fine and smooth, and hardness is good, and durability against pollution is good, and acid and alkali-resistance ability is good, does not affect the secondary decoration technology requirements such as applique.
