Description
Technical field
The present invention relates to a kind of cutter and preparation method thereof, particularly, the present invention relates to a kind of sintex and preparation method thereof, belong to ceramic technology field.
Background technology
Along with the development of science and technology and the raising of people's living standard, the environmental consciousness of people is constantly strengthened.Simultaneously because environmental degradation, global warming impel bacteria breed, produce infection, the sickness rate of catching an illness and also progressively rise.Especially SARS virus, wreaking havoc of bird flu more allow people recognize the importance that home environment purifies.In prior art, tableware, the cutter of the daily practicality of family are metal substantially, if cleaning of finishing using is not in time or thorough, and easy breed bacteria.
At present, industrially developed country in some public places, such as: hospital, dining room, senior house etc., start to promote antiseptic sanitary goods.The antiseptic-germicide of this anti-bacteria ceramic mainly contains several as follows:
1, inorganic silver system doping type anti-bacteria ceramic.Antiseptic-germicide is the combination of the metal ion such as argentiferous, copper and certain carrier, i.e. silver-series antibacterial agent.This kind of antiseptic-germicide is mainly used in pottery, cover-coat enamel, makes it keep anti-microbial property after burning till.
Its main weak point is: 1) antiseptic-germicide is generally used for surface or the cover-coat enamel of pottery, limits its Application Areas; 2) metal ion long-term exposure in atmosphere, the easily variable color because of oxidation; 3) argent is more valuable, and cost is high.
2, TiO 2 series photocatalysis antibacterial agent material.Antiseptic-germicide is nano-photo catalytic semiconductor material, such as: titanium dioxide is admired, zinc oxide etc., this kind of anti-biotic material also needs by certain technique means, one deck antibacterial film is formed on the surface of pottery, such as: adopt sol-gel method nanometer titanium dioxide to be attached to by the emperor himself in the form of a film the glaze paint of pottery, then through low temperature (being generally less than 700 DEG C) barbecue, the ceramic with anti-microbial effect is made.
Its weak point is mainly: 1) photoabsorption of nano-antibacterial layer and photochemical catalysis usefulness lower, particularly greatly will reduce in the dark and even lose antibacterial and bactericidal effect; 2) thermotolerance of antibiotic layer, durable antibiotic and security are poor.
