<P>Purely physical treatment, does not change the traits of wood itself, such as the lock structure. Modification, including chemical modification and physical modification,light weight wall panel is through the preparation, high temperature and other means and methods, destruction of wood microstructure, change the original properties of wood.</P>
<P>Carbonization: The wood is treated at high temperature, the wood floor in the evaporation of water, so that the wooden floor moisture content below 5%. This approach does increase the stability of the wood. But at present,inexpensive deck flooring in sydney China's carbonization process is still in a groping stage, but the technology off.</P>
<P>This too low moisture content, the wood fibers must be the existence of water molecules have also been deprived of, so that the wood has become a "dead wood" state,steel deck price in maila lost the function of exchange with the air, lost on the indoor temperature and humidity Regulating effect, lost the flexibility of foot feeling, the original natural fragrance of wood,waterproof decking systems in seattle but also lost the original toughness, become very fragile, easy to break.</P>
