Wood in this program from heat change to cool, inside the wood cell will be affected to a certain extent, thus resulting in negative pressure back due to a certain extent by thermal expansion and contraction, then further absorption of flame retardant wood fire retardant liquid under the action of pressure, so as to improve the quality of fire retardant treatment of China Fire Door.
