NOVELTY - Mosquito-repelling anticorrosion and antibacterial machining of folding fan framework made of bovine bone comprises e.g. (i) degreasing, (ii) preparing antibacterial anticorrosive solvent, (iii) preparing antimicrobial preservative clinker, grinding and placing in reaction vessel, (iv) heating, placing the folding fan framework made of bovine bone and boiling, (v) stopping heating and allowing to stand, (vi) cleaning with water spray and drying, (vii) fumigating, (viii) wiping the surface, (ix) spraying high oleic bovine bone maintenance solution and drying, and (x) cleaning the surface.    USE - The method is useful for mosquito-repelling anticorrosion and antibacterial machining of folding fan framework made of bovine bone (claimed).    ADVANTAGE - The method is environmentally friendly, safe and economical. The folding fan framework is not easy to crack and has health care effect.    DETAILED DESCRIPTION - Mosquito-repelling anticorrosion and antibacterial machining of folding fan framework made of bovine bone comprises (i) soaking bovine bone in 0.5-0.8% sodium hydroxide solution for 24 hours, removing, soaking in mixture of hydrogen peroxide and 75% sterilizing alcohol for 3-8 hours, where the volume ratio of hydrogen peroxide and sterilizing alcohol is 1:2, (ii) preparing antibacterial anticorrosive solvent, make antibiosis and anticorrosive and placing in a reaction vessel, (iii) preparing antimicrobial preservative clinker, grinding the clinker into 100-200 meshes powder at low temperature and placing in the reaction vessel, (iv) heating the reactor to 80-90 degrees C at the 1.2-1.5 atmospheric pressure, placing the folding fan framework made of bovine bone and boiling for 3 hours, (v) stopping heating, covering with reactor lid at constant temperature and constant pressure condition and allowing to stand for 1 hours, (vi) repeating steps (iii) and (iv) for 2-3 times, removing the folding fan, cleaning with water spray until no presence of deposit, drying the surface quickly without flowing liquid and drying the surface, (vii) crushing Mallotus japonicus bark into particle of diameter 1-2 cm, fumigating in fumigating box, placing the folding fan in fumigating box and removing after 3-5 minutes of retention, (viii) placing the folding fan in a incubator of temperature 60 degrees C for 24 hours, removing and wiping the surface, (ix) drying the surface of the folding fan, placing in spray chamber, spraying high oleic bovine bone maintenance solution and drying at room temperature, and (x) cleaning the surface of the folding fan repeatedly until shiny state patina layer appears.
