| abstract |
The present invention includes a cured film coated from a high hardness inorganic cured film composition having an average particle size of 1.0 to 150 nm on at least one surface of the substrate, wherein the cured film is first baked, baked at 100 to 120 ° C. for 20 to 50 minutes. It is a panel manufactured through a second firing step of firing at 200 ° C. for 20 to 40 minutes and a third firing step of firing at 220 to 300 ° C. for 10 to 30 minutes, and is coated with a superhydrophilic moss adhesion preventing and waterproofing material. The panel is excellent in water resistance, abrasion resistance, chemical resistance, anti-adhesiveness, etc., so it is durable in water with continuous flow for a long time, and it has an economic effect on cleaning, management and operation. |
