Problems solved by technology

However, the surface of this common enamel material may adsorb various bacteria and molds harmful to the human body. In response to this problem, people hope to produce enamel with antibacterial effect. Adding antibacterial agents is one of the methods. Now people The antibacterial agents used are organic antibacterial agents and inorganic antibacterial agents. Among them, organic antibacterial agents are not heat-resistant and are suitable for

Description

technical field [0001] The invention relates to an enamel, especially an enamel with antibacterial effect. Background technique [0002] Inorganic enamel materials have a history of thousands of years. It is a traditional technology. The process is generally based on the designed formula, selecting raw materials (natural minerals, chemical materials, etc.), weighing and mixing them in a high-temperature kiln (1200°C) ~1350℃) to melt into a glass-like substance, and then quenched or pressed into pieces to make a glaze block, and add an appropriate amount of grinding additives to the glaze block, such as: clay, dielectrics, pigments and water, etc., and grind them together in a ball mill It is made into a certain fineness, made into a glaze slurry, and coated on various metal surfaces that have been cleaned in advance, and melted into a smooth and shiny enamel layer at a temperature of 750 ° C to 900 ° C. However, the surface of this common enamel material may adsorb various ...
