阻燃木材处理(FRT)是通过压力使木材浸透阻燃化学品的过程。It is a protective treatment that reduces the combustible nature of wood, minimizes the effects of fire, and is suitable for interior and exterior wood, dimensional lumber, engineered lumber (excluding wood wafer products), and finish materials. Two types of FRT exist today: one involves a blend of a nitrogen-phosphorus organic compound and boric acid, and the other involves the use of ammonium polyphosphates with additives (boric acid, borax, moldicides, and others). Formulation compositions used to treat wood are proprietary and differ between manufacturers.
