Problems solved by technology

[0002] At present, there are high raw material, fuel and labor costs in daily-use ceramics, and the production cost of conventional ceramic products is high, especially bone china products. With the improvement of living standards, no matter household porcelain or hotel porcelain, Higher individual requirements for porcelain
At present, the production of special-shaped parts mainly adopts pressure grouting. The labor intensity of workers is high, requiring high labor skills, and more plaster molds are used. It is urgent to solve the technical problems of batch molding and firing of bone china special-shaped products, and improve bone quality. The regularity of special-shaped porcelain products reduces energy consumption, reduces firing temperature difference, improves product quality, and solves the rapid mass production technology of special-shaped bone china imitation saggers

Embodiment 1

[0019] This embodiment discloses a specific bone china material containing synthetic bone powder and a preparation method thereof.

[0020] Take calcium hydroxide, add water and stir evenly to form a calcium hydroxide suspension, control its water content to 60%, use the ratio of calcium hydroxide: industrial phosphoric acid = 1:0.9, slowly spray and add industrial phosphoric acid, and stir while adding , so that the suspension is not agglomerated, after adding phosphoric acid, stir or stand for one hour to react, control the pH value = 9, squeeze the mud to filter out the water, after drying, calcined at 1200 ° C to form a synthetic compound for production bone meal;

[0021] Take 9 parts of quartz, 12 parts of potassium feldspar, 26 parts of kaolin, 6 parts of ball clay, 36 parts of natural bone meal, 10 parts of synthetic bone meal, and 0.1 part of CMC, and grind them into a ball mill for 25 hours, and the fineness is controlled at 325 mesh sieve. 0.3%, the mud is squeezed...

Embodiment 2

[0027] This embodiment discloses a specific bone china material containing synthetic bone powder and a preparation method thereof.

[0028] Take calcium hydroxide, add water and stir evenly to form a calcium hydroxide suspension, control its water content to 65%, use calcium hydroxide: industrial phosphoric acid = 1:0.94, slowly spray and add industrial phosphoric acid, and stir while adding , so that the suspension is not agglomerated, after adding phosphoric acid, stir or stand for two hours to react, control the pH value = 10.5, squeeze the mud to filter out the water, after drying, calcined at 1280 ° C to form a synthetic compound for production bone meal;

[0029] Take 6 parts of quartz, 15 parts of potassium feldspar, 27 parts of kaolin, 10 parts of ball clay, 26 parts of natural bone meal, 20 parts of synthetic bone meal, and 0.15 part of CMC, and put them into a ball mill for 25 hours, and the fineness is controlled at 325 mesh sieve. 0.2%, the mud is squeezed after i...

Embodiment 3

[0034] This embodiment discloses a specific bone china material containing synthetic bone powder and a preparation method thereof.

[0035] Take calcium hydroxide, add water and stir evenly to form a calcium hydroxide suspension, control its water content to 62%, use calcium hydroxide: industrial phosphoric acid = 1:0.94, spray and add industrial phosphoric acid, and stir while adding, To prevent the suspension from agglomerating, after adding phosphoric acid, stir or let it stand for an hour to control the pH value = 9.5, squeeze the mud to filter out the water, and after drying, calcinate at 1250°C to form synthetic bone powder for production ;

[0036] Take 14 parts of quartz, 8 parts of potassium feldspar, 25 parts of kaolin, 7 parts of ball clay, 30 parts of natural bone meal, 16 parts of synthetic bone meal, and 0.12 parts of CMC, and grind them into a ball mill for 25 hours, and the fineness is controlled at 325 mesh sieve. 0.1%, the mud is squeezed after iron removal ...

Abstract

The invention relates to a special type bone china material containing synthetic bone powder. The special type bone china material comprises, by weight, 6-15 parts of quartz, 8-15 parts of potassium feldspar, 25-30 parts of kaolin, 5-10 parts of ball clay, 26-36 parts of natural bone powder, 10-20 parts of synthetic bone powder, and 0.1-0.15 part of CMC. The invention further provides a preparation method of the synthetic bone powder and a preparation method of the special type bone china material containing the synthetic bone powder. The transmittance of light of bone china products prepared through the method is remarkably increased, thermal impact resistance is substantially enhanced, particle distribution of the bone china pug is optimized, and the plasticity of the pug is obviously improved.

Description

technical field [0001] The invention relates to a specific bone china material containing synthetic bone powder and a preparation method thereof. Background technique [0002] At present, there are high raw material, fuel and labor costs in daily-use ceramics, and the production cost of conventional ceramic products is high, especially bone china products. With the improvement of living standards, no matter household porcelain or hotel porcelain, The individual requirements for porcelain are relatively high. At present, the production of special-shaped parts mainly adopts pressure grouting. The labor intensity of workers is high, requiring high labor skills, and more plaster molds are used. It is urgent to solve the technical problems of batch molding and firing of bone china special-shaped products, and improve bone quality.
