Technical Field
[0001] The utility model relates to the field of color steel plates, in particular to a clean color steel plate with a high-efficiency sterilization core plate. Background Art
[0002] Color steel plate is a product made of cold-rolled steel plate and galvanized steel plate as the substrate, which is subjected to surface pretreatment, coated with paint in a continuous method, and baked and cooled. Color steel plate is mainly used for the roof walls of industrial and commercial buildings such as steel structure factories, airports, and hospitals. Existing medical rooms and other places that need sterilization and disinfection will use antibacterial color steel plates, but the antibacterial color steel plates on the market usually add an antibacterial material layer inside the color steel plate. The antibacterial color steel plates processed in this way usually have an inner core in a closed space. Anaerobic bacteria are easily bred inside the color steel plate, and there are many types of anaerobic bacteria. The antibacterial material layer inside the color steel plate cannot effectively inhibit the reproduction of various anaerobic bacteria. For example, although Bacillus subtilis is an anaerobic bacterium, it has good tolerance to antibacterial materials. The sterilization layer installed inside the color steel plate cannot effectively inhibit the growth of such bacteria, and the sterilization effect is not ideal. Utility Model Content
