When using this method to sinter ceramics, it is required to sinter at 1200-1650° for 1-4 hours. Not only the higher the sintering temperature, the higher the energy consumption, but also because the sintering temperature is too high, it will break the nano-powder and nano-silver antibacterial agent. structure, the lower the antibacterial rate, the lower the antibacterial performance

specific Embodiment 1
[0031] The nano antibacterial ceramic tea set includes a body, an inner glaze layer and a nano antibacterial glaze layer, and the nano antibacterial glaze layer only exists on the inner wall of the tea set; wherein
[0032] The body, in parts by weight, has a specific formula as follows: clay 35, feldspar 25, quartz 15, Longyan kaolin 3, titanium dioxide 7, aluminum dioxide 13, ashes 2.
specific Embodiment 2
[0033] The nano antibacterial ceramic tea set includes a body, an inner glaze layer and a nano antibacterial glaze layer, and the nano antibacterial glaze layer only exists on the inner wall of the tea set; wherein
[0034] Nano antibacterial glaze layer, according to parts by weight, its glaze formula is as follows: frit 45, feldspar 16, clay 13, quartz 8, aluminum dioxide 7, nano silver 3, nano zinc 7, carboxymethyl fiber Prime 1.
[0035] The nano antibacterial ceramic tea set of specific embodiment one and two, its manufacturing process comprises the following steps:
[0036] Step 1, preparing tea set green body and nano antibacterial glaze according to the raw material formula;
[0037] Step 2, after the green body is naturally dried, put it into a kiln, and biscuit at a temperature of 600-800°C to make a biscuit;
[0038] Step 3, after the biscuit is naturally cooled, first apply a layer of ordinary glaze on the biscuit, and then apply a layer of nano-antibacterial gla...

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.
Description
technical field [0001] The invention belongs to the field of ceramics, and in particular relates to a nano antibacterial ceramic tea set and a manufacturing process thereof. Background technique [0002] With the continuous improvement of people's living standards, ceramic production has also developed rapidly. Antibacterial ceramics are a new type of functional material to protect the environment. They are the product of the combination of antibacterial agents, antibacterial technology and ceramic materials. A combined product. While maintaining the original function and decorative effect of ceramic products, it increases the functions of disinfection, sterilization and chemical degradation. [0003] Existing preparation methods for preparing antibacterial ceramics have multiple methods, such as the disclosed inorganic antibacterial ceramics and production process of CN1279222A as the publication number, the preparation method of this kind of antibacterial ceramics is to ad...
