Abstract
Available bone porcelain as high-grade product has the demeritis of high bone powder cost, unstable quality and poor heat stability. The present invention overcomes the said demerits through reducing bone powder amount to reduce product cost, and first low temperature baking before glazing and then high temperature baking after glazing process to result in high glaze hardness and high heat stability and produces product with high whiteness and transparency.
Description
The production method that the invention belongs to the bone china series products and produce this product.
At present, sclerotin porcelain series products impressively ranks top in the expensive goods of domestic and international ceramic market, but because the required bone ash amount of production sclerotin porcelain is bigger, generally at 35%-55%, and the cost height of bone ash, so the product price height, supply bottleneck.In addition, it also has many deficiencies, as: the quality instability, thereby sclerotin porcelain production control difficulty is big, and also the bone china hardness of glaze surface is low, poor heat stability etc.
The objective of the invention is to produce a kind of low bone ash content, porcelain exquisiteness, transparency height, hardness of glaze surface height, the new bone porcelain of Heat stability is good.
Deironing → pug processing → female mould forming → low temperature biscuiting → refine base → glazing → grand feu → select ceramic whiteware → decoration firing → faience sorting → packing to dispatch from the factory.
The present invention is the bone ash that adds 2%-10% on the basis of feldspathic china prescription, makes it obtain bigger high temperature viscosity; Behind female mould forming,, carry out 1320 ℃ of-1350 ℃ of grand feus again and form with 850 ℃ of-1050 ℃ of low temperature biscuitings, glazing then.
The present invention has compared following characteristics with the sclerotin porcelain: 1) adopt 1320 ℃ of grand feus, hardness of glaze surface height; 2) bone ash content is low, and production cost is low, Heat stability is good; 3) have sclerotin porcelain whiteness, transparency is good, the characteristics that tone is soft, it is low to have remedied sclerotin ceramic glaze surface hardness, the defective of poor heat stability, and having than common ceramic whiteware whiteness height, the advantage that transparency is good.
Narrate the concrete characteristics of new bone porcelain and production technique thereof below: new bone porcelain is to have carried out bold breakthrough on the feldspathic porcelain basis, use for reference the strong characteristics of southern porcelain district sericite porcelain non-deformability, introduced the porcelain stone raw material, the bone ash that when batching, adds 2%-10%, 5%-8% preferably, blank processing fineness is the surplus 0.08-0.1% of 10000-hole sieve, makes the fully reaction fusion in burning till of each component, reduce the broken base effect that residual particles and quartzy crystal conversion bring, help mineralization; The difference of the production technique of the production technique of this new bone porcelain and sclerotin porcelain is: behind female mould forming, use the low temperature biscuiting, temperature preferably is controlled at 900 ℃-1000 ℃, refine base substrate after the low temperature biscuiting, grand feu again after the glazing, temperature preferably is controlled at 1325 ℃-1340 ℃, and other technology is produced identical with the sclerotin porcelain.
Claims (4)
