won't cause wet bilge drying shrinkage, the floor is changeless form, but lumber becomes plastic. Carbonization is to point to with 190 ?---The high temperature high pressure of 212 ? undertakes be heatinged up for long solving handling to lumber. Carbonization has two kinds of technology, exterior carbonization is barbecue of
buy outdoor composite wall panels welding torch that use oxygen, make lumber surface has a very thin char layer, OK to the change of lumber function the paint of analogy lumber.Deepness char wood also calls complete char wood, coessential char wood, it is the lumber that the technical divisions of high temperature char that controls through 200 degrees manages,
wood fence boards for sale its nutrition composition is destroyed, its are bibulous and luscious round semi-cellulose is recombined, wet bilge drying shrinkage rate falls.
Carbonization makes the polysaccharide inside wood (cellulose) pyrolysis forms monose, monose adheres to in lumber surface. As the growth of time, the surface is easy happen decayed,composite decks for front the surface is shown Brown or black Brown. In the meantime, the capability that carbonization wood absorbs combinative water is not strong, but the capability that absorbs free water is very strong. For slow down these phenomena, can paint in the three-layer of exterior cover with paint of char wood.
