For enamel products related to daily life, the requirement for antibacterial properties is a current development trend both domestically and internationally. Antibacterial properties, in their sense, include sterilization, disinfection, and bacteriostasis. In this article, antibacterial activity refers to inhibiting bacterial proliferation and reproduction, not sterilization or disinfection.
There is no universally accepted explanation for the antibacterial mechanism of antibacterial porcelain enamel. Generally, there are two main explanations: 1. Silver and copper ions dissolved from the surface of the antibacterial porcelain enamel enter the bacteria, destroying their proteins and causing them to die. 2. The catalytic effect of silver alters oxygen activity, damaging the surface structure of the bacteria. Antibacterial enamels using a mixture of silver and copper primarily exhibit the first explanation.
Generally, porcelain enamel surfaces are relatively hard and chemically stable, attracting oil and bacteria. To easily remove these contaminants, the enamel surface layer must possess properties that inhibit bacterial growth. This article discusses the antibacterial effect of enamel.
Methods for evaluating antibacterial properties include the inhibition zone method, the drop test, and the film adhesion test. The film adhesion test is generally used to evaluate the antibacterial properties of enamel surfaces. The film adhesion test method is described in some literature and is used in testing many antibacterial products.
The evaluation of antibacterial properties in this study relies on specialized medical institutions.
