PRESSURE-TREATED NONINFLAMMABLE LUMBER MANUFACTURING METHOD

摘要

A flame retardant-treated wood processing method and a device are provided to process flame-retardant wood within a short time by applying a carbon diluted medicinal fluid for effectively removing carbon included in the wood, improving strength, and keeping the shape stable. A flame retardant-treated wood processing method comprises the steps of: putting wood to be treated(5), into a pressure tank(10) having a wood containing part(11); exhausting the air included in the wood by applying vacuum pressure to the containing part of the pressure tank; preparing medicinal fluid including a carbon diluted solution penetrating through quartz diorite; dipping the wood in the medicinal fluid by filling up the containing part of the pressure tank with the medicinal fluid; injecting the medicinal fluid into the wood by pressing the containing part of the pressure tank; recovering the medicinal fluid remaining on the surface of the wood and the containing part by applying vacuum pressure to the containing part of the pressure tank; releasing vacuum pressure applied on the containing part of the pressure tank; and drawing and drying the wood stored in the containing part of the pressure tank.
