Antibacterial glass-composite coatings for protection of special purpose steel panels

Abstract

It has been established that the most informative and universal method for determination of biocide properties of vitreous coatings is qualitative method that takes into account the growth level of biotest microorganisms inoculated into liquid nutrient media. It is shown, that biocidity of glass-composite coatings on the basis of glasses of Na₂O–K₂O–CaO–ZrO₂–TiO₂–Al₂O₃–P₂O₅–B₂O₃–SiO₂ system is determined by the presence of calcium phosphates in them and depends on the type of bactericide filler. The most effective ones by the action on Pseudomonas aeruginosa bacterium and Aspergillus niger and Саndida albicans fungiare zinc titanate and Ag⁺, to Escherichia coli- only zinc phosphate.
