Preparation And Application Of The Ag-type Inorganic Composite Antibacterial

The research and development of the antimicrobial has been attented extensively since O-157 colon bacillus' contamination accident has happened in Japan. As a new industry, the research and production of the antimicrobial has very important realistic meanings. Many of silver series inorganic antimicrobial researches and reports can be found at present domestic and international magazines, but they concentrate on the choice and quantity of antibactial ion mostly, and seldom the reports can be found about the influence of other components and antibactial performance of pre & post heat treatment. There are so many condition of overcommitting the antimicrobial in order to pursue the antibacterial performance. Not only the costs of products are rised, but also the contamination of mental ion on the product and enviroment may be caused.In this paper, we import the atoms of zinc,boron and phosphorus in the Ag-type antibmicrobial system, and produce the more stronger antibacterial than sigle Ag-type antibacterial. The influence of phosphorus ion, zinc ion and boron ion to the SiO2-ZnO-B2O3-CaF2-AgCl system of inorganic antibacterial, the change of antimicrobial performance after being dealed with high temperature, is researched. Antimicrobial performance changes like curve with the ration of P&Ag, Si&Zn and Si&B increasing. The antimicrobial and the sample of antibacterial ceramics were studied with XRD(X-ray Diffraction), XPS(X-ray Photoelectron Spectroscopy), SEM(Scanning Electron Microscope), light microscope, gas adsorption method, particle size analysis, antimicrobial property test and toxicity test to investigate the influential factors to the properties of antimicrobial and the factors in its use of the glaze of ceramics and their relations.As a result, the most suitable joining amount is that the ratios of P&Ag are 3,the rations of Si&Zn are 3, and the ratios of Si&B are 2. The antimicrobial performance is steady in 50ppm after the test of resisting high temperature.The inorganic antimicorbial are used in the glaze of ceramics. The research resultshows that the antibacterial rate of the antibacterial ceramics can attain above 99.9% by adding 2.5wt% antimicrobial in the glaze. The antibacterial ceramics using this antimicrobial has characteristics such as good quality in glaze and permanence in antibacterial effects.
