Description
Technical field
The present invention relates to a kind of Technology of using sol-gelatin plating method to produce antibiotic glass, belong to the deep processing field of sheet glass.
Technical background
Along with socioeconomic continuous development and human living standard's raising, glass from single daylighting, have an X-rayed and the function development of keeping out wind and rain to multifunctional glass product with various special purposes.In recent years, because SARS virus and avian influenza virus be to the mankind's invasion and attack, all trades and professions are particularly outstanding to the demand of antibiotic glass and antibiotic glass product.Therefore, the research of relevant antibiotic glass in recent years develops rapidly, is applied to different industries, and the antibiotic glass of different field emerges gradually.
The processing and fabricating of antibiotic glass is that antiseptic-germicide is added on the glass carrier, makes it have antibacterial, the sterilizing function of contact-type.The contact-type anti-biotic material, the surface of material must possess the contact antibacterial under unconditional normality.Therefore, the coating process technology of glass surface is the technological core in the antibiotic glass processing.
Traditional sheet glass film coating method mainly contains three kinds at present, first kind is online chemical vapor deposition (CVD) method, second kind is the on-line spray method, produce antibiotic glass with these two kinds of methods, mainly there is following problem: the one, glass space temperature in coating process is too high, easily make the antiseptic-germicide oxidation deactivation, the 2nd, aforesaid method can only carry out plated film at the single face of glass, the result of use and the scope of antibiotic glass have been limited, the mode of production is dumb, and the third is the vacuum sputtering coating method, makes antibiotic glass with this method, have following problem: antiseptic-germicide is to exist with atomic condition on the surface of glass at last, and antibacterial is difficult to be up to state standards under normal conditions; And the antibacterial film belongs to " mantle ", is not suitable for long-term exposure and contacts use.
