Composite antibacterial far infrared medical stone porous ceramic ball and preparation method thereof

Abstract

The invention relates to a composite antibacterial far infrared medical stone porous ceramic ball. The surface of the porous ceramic ball is in the form of a closer porous sintered structure while the internal structure of the porous ceramic ball is three-dimensional communicated micropores which are uniformly distributed as a whole and are interlaced and connected with each other; the particle size of the porous ceramic ball is 10 microns to 5 millimeters; the volume density is 1.0-2.8 g / cm<3>; the porosity is 30-50%; the aperture size is 10-100 microns; and the compressive strength is 10-18 MPa. The porous ceramic ball is prepared from a ceramic natural mineral, a high temperature synthetic ceramic raw material and a pore-forming and binding material through the following processes of finely crushing, proportioning, pelletizing, sintering at low temperature, washing with water and drying, and the porous ceramic ball comprises the following components in parts by weight: 5-15 parts of lead-free and cadmium-free low temperature solvent, 5-15 parts of silver-loading analcite, 3-6 parts of nano-anatase TiO2 (Titanium Dioxide), 5-15 parts of high temperature synthetic far-infrared material, 5-15 parts of natural electric stone, 40-50 parts of medical stone and 10-20 parts of pore-forming and binding material. Because good whole sintering degree and a porous structure are remained and the surface of the porous ball is easy to grind, decontaminate and wash by adopting a self-created preparation process of uniformly dispersing the nano-TiO2 powder in the slurry without agglomeration, the porous ceramic ball has the advantages of strong regeneration capacity and long service life.

Description

technical field [0001] The invention relates to a composite antibacterial far-infrared medical stone porous ceramic ball, in particular, it is used as a functional adsorption and impregnation material in drinking water cups, water dispensers, and field water purifiers for purifying, antibacterial, and activating water. Applied porous ceramic ball and preparation method. Background technique [0002] In the water purification and mineralization treatment of the prior art, three types of materials are most commonly used: medical stone, activated carbon and ordinary porous ceramic balls. Commercially available medical stone products include medical stone "powder" with a fineness of 80-325 mesh and solid "medican stone balls" with a particle size of 0.1-9mm. The original medical stone powder has gradually withdrawn from the field of water purification and mineralization treatment, and has been replaced by solid medical stone balls. Activated carbon generally adopts granular ac...

Problems solved by technology

[0004] The water activation treatment in the prior art often uses natural tourmaline to introduce, so the effect of far-infrared activated water is not obvious. If the composite introduction of optimized high-temperature artificially synthesized far-infrared ceramic powder and natural tourmaline is used, the water activation treatment can be optimized.
