For ordinary wooden doors, because the wood is not further processed, anticorrosive treatment is required. The wood of the wooden fire door has a special requirement in the national standard for fire doors, that is, it must be flame-retardant treated and other relevant environmental protection requirements. The process of flame retardant treatment is to make the flame retardant penetrate into the core of the wood by vacuuming and pressing in a vacuum pressure tank. To ensure that each piece of wood on the fire door can meet the flame retardant requirements, and the flame retardant penetrates into each layer of the wood, and also plays a role in preventing deformation and corrosion. With anti-corrosion and insect-proof effect. For this reason, any wooden fire door made of wood that has undergone a flame retardant treatment does not need to be subjected to a separate traditional anticorrosive treatment.
