Abstract
The present invention belongs to the technical field of the manufacture of a domestic ceramic, which relates to a novel formula for a body material and a glaze material, which utilizes the glaze firing temperature slightly lower than stoneware to fire a domestic ceramic whose the strength is higher than the strength of a hard ceramic. The body material has the formula of 50 to 58% of silicon dioxide, 30 to 38% of aluminium oxide, 5 to 15% of calcium oxide, 0 to 3% of magnesium oxide, 1 to 6% of potassium oxide and 0 to 4% of sodium oxide. The glaze material has the formula of 55 to 65% of silicon dioxide, 10 to 18% of aluminium oxide, 12 to 20% of calcium oxide, 1 to 5% of magnesium oxide, 0 to 3% of sodium oxide, 1 to 5% of strontium oxide, 0 to 3% of barium oxide, 0 to 5% of potassium oxide and 0 to 3% of lithium oxide. The present invention has the advantages that the glaze firing temperature and the glaze firing time are lowered, the quality is improved, the energy consumption is saved, and the cost is decreased.
Description
Technical field the invention belongs to domestic ceramics manufacturing technology field, and the particularly new formulation of ceramic batch and glaze is with the performance of improving the quality of products, reduce glaze and burn till the porcelain temperature and time, energy efficient reduces cost, can be used widely at ceramic industry.
Background technology household china commonly used has hard-paste and Shi porcelain, and the two key distinction is burnt till the porcelain temperature in blank and glaze formula and glaze.Hard-paste intensity is good, whiteness is high, water-intake rate is low, but glaze burns till the porcelain temperature up to 1330 ℃-1350 ℃, and the glaze firing cycle reaches 5.5 hours, and fuel consumption is big, and the glaze firing operation finishes in reducing atmosphere, is unsuitable for the exploitation of color glaze.Though the glaze firing operation of Shi porcelain is finished in oxidizing atmosphere, glaze burns till 1220 ℃-1250 ℃ of porcelain temperature, be lower than about 100 ℃ of hard-pastes, but the glaze firing cycle reaches 6 hours, the same fuel consumption that increases, the Shi porcelain products are of poor quality in addition, whiteness is low, water-intake rate is high, and smooth finish is low, acid-alkali-corrosive-resisting and anti-knife and fork are drawn shortcomings such as carving difference, can only list low-grade porcelain in, not appeal to refined taste.
Summary of the invention the objective of the invention is to overcome the deficiency of above-mentioned prior art, select its two advantage, develop rational blank and glaze formula, make its temperature of glaze firing reduce to 1200 ℃-1220 ℃, the glaze firing cycle reduces to 4.5 hours, and in oxidizing atmosphere completely, fire and form, be beneficial to colourful color glaze exploitation, be specially adapted to glaze and set about color.The porcelain temperature of burning till the Shi enamel that the present invention compares reduces by 10 ℃-50 ℃, and the glaze firing cycle shortens 1.5 hours, than the hard-paste glaze burn till the porcelain temperature and reduce by 110 ℃-130 ℃, the glaze firing cycle shortens 1 hour.Energy efficient 10-30% reduces production costs greatly.Utilization of the present invention successfully burns out the household china that is higher than hard-paste intensity a little less than the temperature of glaze firing of Shi porcelain, so the superpower soft-paste of name.
As everyone knows, ceramic batch is mainly mixed according to different proportionings by raw materials such as feldspar, quartz, kaolin, white clay, aluminium powder, rhombspars, glaze formula is mainly mixed by raw materials such as feldspar, frit, white clay, rhombspar, calcite, triphane, quartz, aluminium powders, the intensity of blank decision product, the class of glaze decision product.The present invention reasonably prescription is that the blank porcelain temperature of will hoping for success is lower, forms fine and close mullite structure, increases physical strength; Glaze requires to generate more glassy phase, and bright in luster, attractive in appearance beautiful, erosion resistance is strong, and anti-knife and fork is drawn quarter, Heat stability is good, unleaded, cadmium stripping.
A kind of superpower soft-paste manufacture method of the present invention's development, it is characterized in that: glaze firing becomes 1200 ℃-1220 ℃ of porcelain temperature simultaneously, and the glaze firing cycle is 4.5 hours; The Chemical Composition weight percent of blank is:
Silicon-dioxide SiO
253-58% magnesium oxide MgO 2-3%
Aluminium sesquioxide Al
2O
332-38% potassium oxide K
2O 2-6%
Calcium oxide CaO 5-10% sodium oxide Na
2O 1.5-4%;
The characteristics of blank formulation of the present invention are: aluminium sesquioxide Al
2O
3Additional proportion is bigger, approaches the formula rate of hard-paste, but has increased the add-on of strong fusing assistant rhombspar, effectively reduce blank and become the porcelain temperature, be beneficial to and form fine and close mullite structure at a lower temperature, guarantee the high 20-50% of hard-paste that product strength compares, water-intake rate is less than 0.1%.
Said glaze formula is to be based upon on the basis of blank formulation, makes its blank and glaze interpenetrate and fuse when sintering, and the two is closely linked, and glaze formula is mainly by calcium oxide CaO, aluminium sesquioxide Al
2O
3, silicon-dioxide SiO
2Form, and contain a spot of potassium oxide K
2O, sodium oxide Na
2O, magnesium oxide MgO, strontium oxide SrO, barium oxide BaO, Lithium Oxide 98min LiO, the weight percent of its Chemical Composition is:
Silicon-dioxide SiO
258-65% strontium oxide SrO 2-5%
Aluminium sesquioxide Al
2O
315-18% barium oxide BaO 1.5-3%

2O 1.5-3%
Sodium oxide Na
2O 1-3%.
The characteristics of glaze formula of the present invention are suitably to increase aluminium sesquioxide Al
2O
3, magnesium oxide MgO proportioning, to improve glaze self hardness, add strontium oxide SrO and barium oxide BaO simultaneously; to reduce vitrification point, promote glaze chromatography crystalline substance, the formation that increases glassy phase; reduce the glaze frictional coefficient, improve thermostability and erosion resistance, guarantee that product is at 1%Na
