Background technology
Bone China is called for short china, formal name used at school bone china, for main raw material with the bone carbon of animal, clay, feldspar and quartz, through a kind of porcelain that high temperature biscuiting and low temperature sinter are fired for twice, according to the china standard set by Britain, containing 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 then minimum will reach 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 paint, can be by force ornamental, 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 the special porcelain of British royal and noble for a long time, is the high-grade porcelain kind of generally acknowledging in the world at present, it has dual value that is practical and art concurrently, be right and status symbol, be also the embodiment of life grade, be known as " king of porcelain ".
Bone China good decorative property is the natural characteristics that other porcelain cannot be comparable, and current high-grade bone china faience is that the trailing being posted in-glaze decoration marble paper on white quality china goods makes, and its technological principle is that colorant is molten in glaze layer in roast process; Chinese red, the yellow low temperature color glaze decoration of emperor have been widely used in sclerotin porcelain, and decoration technology complexity is various.The reasons such as due to technological reason, it is low that low-temp exists hardness of glaze surface, and anti-pollution characteristic is poor, acid-alkali-corrosive-resisting ability, never use matt glaze in china product decoration.
Summary of the invention
In order to realize the making of above-mentioned sclerotin matt glaze, the invention provides a kind of sclerotin matt glaze and the method with this glaze making Bone China product.
For achieving the above object, the present invention by the following technical solutions:
A kind of sclerotin matt glaze, comprises following component and weight proportion number: frit 100 parts, clay 3 ~ 8 parts, wollastonite 2 ~ 12 parts, 3 ~ 6 parts, aluminum oxide, 6 ~ 15 parts, zinc oxide, 6 parts, stannic oxide; Wherein, described frit comprises following component and weight proportion number: 16 ~ 24 parts, quartz, potassium felspar sand 28 ~ 38 parts, borax 12 ~ 18 parts, boric acid 0 ~ 7 part, Strontium carbonate powder 0 ~ 5 part, Quilonum Retard 0 ~ 8 part, 0 ~ 10 part, zinc oxide, 0 ~ 3 part, talcum, calcite 0 ~ 12, zirconium silicate 0 ~ 0.5 part.
Make a method for Bone China product of sclerotin matt glaze according to claim 1, method steps is:
S1: the raw material stirring in being filled a prescription by described frit is even, melts, make frit for subsequent use at 1300-1330 DEG C of temperature;
S2: get the frit obtained in S1, enters mill by the raw material in described glaze formula, is benchmark, adds the water that mass percent is 30-32% with total mass, grinding 48-55 hour, and fineness 325 mesh sieve residue≤0.1%, crosses 200-250 mesh sieve, for subsequent use;
S3: the glaze obtained in S2 glaze spraying in bique dried, glazed thickness scope is 6 grams/100 cm
2, enter kiln oxidation and fire, firing condition is: normal temperature heats, with the ramp of 3 ~ 5 DEG C/min to 360 DEG C, then with the ramp of 2 ~ 4 DEG C/min to 900 DEG C, then with the ramp of 1 ~ 2 DEG C/min to 1150 ~ 1180 DEG C, 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 precipitation crystallite, and silica alumina ratio controls the scope at 10:1 and boron oxide about 8%, is conducive to crystallization; Stannic oxide has good milkiness effect, is conducive to crystallization simultaneously, improves porcelain glaze paint whiteness, and the difference collocation of wollastonite and zinc oxide, can adjust the glaze of different maturing temperature.Zinc oxide, boron oxide, aluminum oxide, stannic oxide acting in conjunction, be both conducive to crystallization, prevents again crystal from growing up.
Compared with prior art, the present invention has following beneficial effect: glaze paint 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.
