Problems solved by technology

Due to the excellent properties of ceramic materials, people usually use ceramics to store food and drinks, but the existing ceramic containers can only be used for storage and cannot play a greater role
[0003] At present, activated carbon and diatomite are mostly used for drinking water filtration and purification at home and abroad. Due to their limited durability and exchange function, and the inability to separate out elements and minerals that are beneficial to the human body, they will gradually be eliminated.

Embodiment 1

[0019] A kind of medical stone porous ceramics, the weight percentage of its raw material is: 40% of alkaline feldspar; 39.5% of plagioclase; 20% of quartz; 0.5% of carboxymethyl cellulose. The production process steps of its products include: (1) mixing the raw materials evenly according to the proportion, and feeding; (2) grinding according to the mass ratio of material:ball:water of 1:1.5:0.8, and the grinding time is 15 hours; (3) ) Sieve the ground mixture. During the sieving process, use a 250-mesh sieve with a sieve allowance <0.5%, then design according to the application requirements, extrude, and repair the surface to remove the plugging mud; (4) Sinter the obtained green body in an oxidation flame at 1000° C. for 6 hours, and cool with the furnace to obtain the Maifan porous ceramic.

Embodiment 2

[0021] A kind of medical stone porous ceramics, the weight percent of its raw material is: alkaline feldspar 50%; plagioclase feldspar 40%; quartz 9%; sodium humate 1%. The production process steps of its products include: (1) mixing the raw materials evenly according to the proportion, and feeding; (2) grinding according to the mass ratio of material:ball:water of 1:1.5:0.8, and the grinding time is 20 hours; (3) ) Sieve the ground mixture. During the sieving process, use a 250-mesh sieve with a sieve allowance <0.5%, then design according to the application requirements, extrude, and repair the surface to remove the plugging mud; (4) Sinter the obtained green body in an oxidation flame at 1050° C. for 8 hours, and cool with the furnace to obtain the Maifan porous ceramic.

Embodiment 3

[0023] A kind of medical stone porous ceramics, the weight percent of its raw material is: alkaline feldspar 45%; plagioclase feldspar 40%; quartz 14.2%; carboxymethyl cellulose 0.8%. The production process steps of its products include: (1) mixing the raw materials evenly according to the proportion, and feeding; (2) grinding according to the mass ratio of material:ball:water of 1:1.5:0.8, and the grinding time is 18 hours; (3) ) Sieve the ground mixture. During the sieving process, use a 250-mesh sieve with a sieve allowance <0.5%, then design according to the application requirements, extrude, and repair the surface to remove the plugging mud; (4) Sinter the obtained green body in an oxidation flame at 1025° C. for 7 hours, and cool with the furnace to obtain the Maifan porous ceramic.

Abstract

The invention relates to a ceramic material and discloses a medical stone porous ceramic and a preparation method thereof. The medical stone porous ceramic comprises the following materials according to weight percentage: 40-50% of alkali feldspar, 30-40% of anorthose, 10-20% of quartz and 0.5-1% of plasticizer; the medical stone porous ceramic is prepared through the steps of mixing the materials, grinding, forming and sintering. The medical stone porous ceramic chooses a medical stone containing multiple mineral substances and rare earth elements as a base material and has the excellent functions of adsorption and exchange, the properly added plasticizer is favorable for the forming process, and the rate of qualified products and the rate of quality products are increased. The sintering temperature is controlled to better keep the original functions of porosity, adsorption and exchange, and the loss and evaporation of microelements and the rear earth elements are prevented.

Description

technical field [0001] The invention relates to a ceramic material and a preparation method thereof, in particular to a medical stone porous ceramic and a preparation method thereof. Background technique [0002] Porcelain is a comprehensive product of pottery and porcelain. It not only has the air permeability and water absorption of pottery, but also has the characteristics of hardness and watertightness of porcelain, and the material is cheaper. Due to the excellent properties of ceramic materials, people usually use ceramics to contain food and drinks, but the existing ceramic containers can only be used for storage and cannot play a greater role. [0003] At present, activated carbon and diatomite are mostly used for drinking water filtration and purification at home and abroad. Due to their limited durability and exchange function, and the inability to separate out elements and minerals that are beneficial to the human body, they will gradually be eliminated. Content...
