An unfortunate feature of modern life is the large number of fires occur in occupied buildings, statistics show that in many of these fires wood and wood based materials are the first item ignited.
The majority of such fires results from ignition using small energy sources such as matches and many of these fires could have been avoided if the wood and wood based had been treated with a fires-retardant additive designed to import ignition resistance.
A concern over a research and development for an improvement in flame resistant efficiency & duration rises higher and higher in proportion to an increase in wood use, followed by a launch of wood product with high efficiency, but most structural woods among them are used for construction without the addition of the flame retardant substituting flame-resistive plasterboard, the method which should be colorless. scentless flame-resistive state for the use.
Accordingly. this study will carry a work that letting the phosphate flame resistant agent to permeate evenly into the empty space in where the free water and bound water, which are in the cell & lumen internal wood, are evaporated in the microwave within a short time, and compress them to a certain thickness for duration improvement, for the deduction of a basic date for the development of high durability flame resistive and environment friendly structural wood without deforming against a shortened wood seasoning time, weather change and effect of natural environment and harmless to human body.
