Abstract
The invention belongs to the field of ceramics, and particularly relates to a nano antimicrobial ceramic tea set and a manufacturing technique thereof. By improving the formulae of the blank and glaze, the nano antimicrobial ceramic tea set has a nano antimicrobial glaze layer, can destroy the biological structure and normal metabolism of pathogenic bacteria to kill the pathogenic bacteria or inhibit the pathogenic bacteria from reproduction, can eliminate chlorine and other impurities in water, and can increase the dissolved oxygen amount, so that the water tastes smooth and sweet, the tea can wet the throat and has the characteristics of no bitterness and better mouthfeel, and various beverages can be preserved for a longer time. The detection proves that the antimicrobial rate of the nano antimicrobial ceramic tea set for Escherichia coli, Staphylococcus aureus and other pathogenic bacteria is up to higher than 99.9%. The improvement of the manufacturing technique lowers the damage to the structure of the antimicrobial raw material and reduces the use of the antimicrobial raw material; the nano antimicrobial glaze does not directly contact the biscuit due to the double-layer structure, thereby reducing the influence on the glaze surface and enhancing the adhesive power of the nano antimicrobial glaze; and thus, the glaze surface has higher hardness and better heat resistance, and is fine and clear.
