NOVELTY - Processing rosewood bark comprises e.g. (i) placing the formulated preservative solvent in reaction vessel; (ii) grinding the formulating preservative cooked material; (iii) heating the reaction vessel, cooking the rosewood bark; (iv) covering the reaction vessel using lid; (vi) spraying water on the surface of the rosewood bark, and drying; (vii) pulverizing rosewood bark and igniting the rosewood bark; (viii) incubating the rosewood bark; (ix) placing the bark in shower room and spraying high oleic solution; and (x) repeatedly wiping the surface to obtain shiny patina layer state.    USE - Used as rosewood bark.    ADVANTAGE - The rosewood bark has good insect repellent and antibacterial antiseptic effect (claimed) on the environment and human body without poison, is easy to crack anti-oil, greatly enhances antibacterial health effect, and disseminate negative ion effect to human.    DETAILED DESCRIPTION - Processing rosewood bark comprises (i) formulating antimicrobial preservative solvent and placing in a reaction vessel; (ii) formulating antimicrobial preservative cooked material, grinding the cooked material into 100-200 mesh at low temperature, and then placing into a reaction vessel; (iii) heating the reaction vessel to 80-90 degrees C under 1.2-1.5 atmosphere, cooking rosewood bark for 3 hours; (iv) stopping heating, covering the reaction vessel using lid and allowing to stand at constant temperature and pressure conditions for 1 hour; (vi) repeating steps (iii) and (iv) for 2-3 times, removing the rosewood bark, spraying water on the surface of the rosewood bark until no attachments, quick drying until without flowing liquid on the surface, and drying until the surface is dried; (vii) pulverizing rosewood bark to obtain particle diameter of 1-2cm, then placing the rosewood bark in a fumigating box and igniting by passing fumes, hanging the rosewood bark in the fumigating box, maintaining for 3-5 minutes and then taking out the rosewood bark; (viii) incubating the rosewood bark at 60 degrees C for 24 hours, and removing the wipe surface of the rosewood bark; (ix) placing dried surface of the rosewood bark into shower room, spraying oleic acid solution on the surface of the rosewood bark, and drying at room temperature; and (x) repeatedly wiping the surface of the rosewood bark with a cloth to obtain shiny patina layer state.
