Example Embodiment

[0028] Example 1

[0029] The first step, sepiolite pretreatment

[0030] The raw sepiolite ore is beneficiated, washed with water, and naturally dried, and crushed into 10mm particles by a tooth crusher, and then processed by jet milling to obtain sepiolite mineral nanofibers, with an average particle size of 7μm;

[0031] The second step, the production of blanks and bodies

[0032] The raw materials are made into blanks according to the weight percentage of bone powder 30%, Laiyang soil 15%, albite 20%, Datong soil 5%, Fangzi soil 8%, and Longyan soil 20%. Ball: water = 1:2:1 put into the ball mill and add water ball mill, after the raw material of this ratio is ball milled to a particle size of 60μm, add 2% of the sepiolite mineral nanofibers obtained by the first step of sepiolite pretreatment. Continue the ball milling and mixing for 2 hours, and then use the sieve of 120 mesh, 180 mesh, and 200 mesh to sieve three times, remove iron and stale for 15 days under the magnetic fie...

[0035] Example 2

[0036] The first step, sepiolite pretreatment

[0037] The raw sepiolite ore is beneficiated, washed with water, and naturally dried, crushed into 15mm particles by a tooth crusher, and then processed by jet milling to obtain sepiolite mineral nanofibers with an average particle size of 7μm;

[0038] The second step, the production of blanks and bodies

[0039] The raw materials are made into blanks according to weight percentages of bone powder 35%, Laiyang soil 12%, albite 17%, Datong soil 6%, Fangzi soil 10%, and Longyan soil 15%, and put the blank into a ball mill and water ball mill. The proportioned raw materials are ball-milled to a particle size of 70μm and then added to the sepiolite mineral nanofibers obtained by the first step of sepiolite pretreatment. After addition, the mixture is ball-milled for 2.5 hours, and then the mesh size of the screen is 120 meshes. , 180 mesh, 200 mesh sieve for three times, iron removal under a magnetic field strength of 15...

[0043] The first step, sepiolite pretreatment

[0044] The raw sepiolite ore is beneficiated, washed with water, and naturally dried, crushed into 20mm particles by a tooth crusher, and then processed by jet milling to obtain sepiolite mineral nanofibers with an average particle size of 7μm;

[0045] The second step, the production of blanks and bodies

[0046] The raw materials are mixed with 40% bone powder 40%, Laiyang soil 9%, albite 15%, Datong soil 8%, Fangzi soil 5%, and Longyan soil 15% by weight to form a blank, and the blank is put into a ball mill and a water ball mill. The proportion of raw materials is ball milled to a particle size of 80μm and then added to the sepiolite mineral nanofibers 8% obtained by the first step of sepiolite pretreatment. After addition, the ball milling mixture is continued for 3 hours, and then the mesh size of the screen is 120 mesh , 180 mesh, 200 mesh sieve sieved three times, iron removal under a magnetic field strength o...

Abstract

The invention provides bone china and a preparation method thereof and relates to chain forming products characterized by components. The bone china is sepiolite mineral nanofiber toughened bone china and comprises the following components in percentage by weight: bone powder 30-40%; Laiyang soil 9-15%; albite 15-20%; Datong soil 5-8%; Fangzi soil 5-10%; Longyan soil 15-20%; and sepiolite mineral nanofiber 2-8%. The preparation method comprises the following steps: treating sepiolite by a jet mill to obtain the sepiolite mineral nanofiber which is used as raw materials of blank materials by required weight percent; and preparing the raw material into the blank materials by adding water for ball-milling, sieving, deironing and aging and rotting; carrying out blank forming, drying and fettling on the blank materials to obtain a blank body; and then porcelainizing to prepare the sepiolite mineral nanofiber toughened bone china. The bone china has higher toughness, simple preparation process and low preparation cost.

Description

technical field [0001] The technical proposal of the invention relates to a ceramic molded product characterized by its composition, specifically a bone china and its preparation method. Background technique [0002] Bone china has been used by nobles in various countries for a long time because of its unique shape, concise and lively texture, and white and delicate texture. It is currently recognized as a high-grade porcelain in the world. It is a kind of soft porcelain made mainly of calcined bone powder, with some mineral raw materials such as clay, feldspar and quartz added, and fired by high-temperature plain firing and low-temperature glaze firing for secondary firing. CN200810218702.1 discloses a bone china and its production process; CN200810147461.6 discloses a lead-free bone china and its preparation method, the bone china is made of bovine bone carbon, pig bone carbon, Datong sandstone, Composed of quartz, feldspar, kaolin, cooked kaolin and bentonite; CN 9811659...
