The atomic wood is prepared by mixing wood and plastic and then processing the mixture by cobalt 60. Because the wood reinforced by the plastic is more beautiful than the natural wood in pattern and color, and is easy to saw, nail and polish, the wood can be processed by a common woodworking tool.

The fire-retardant wood is made up by adding inorganic salt into fire-resisting material and soaking the selected wood in solution containing barium ion and phosphate ion so as to attain the goal of making wood implement corrosion protection and termite-proofing. The carpet in a room made of the fire-resistant flame-retardant material can not be burnt by fire even if the carpet in the room catches fire, and has good fire-resistant performance.

The composite wood is made up by using polyvinyl chloride as main raw material and adding proper quantity of fire-resisting agent so as to make the wood possess fire-proofing function.

The synthetic wood has the texture of natural wood and the plasticity of resin, has the characteristics of strong waterproofness, convenient processing, difficult deformation and good mothproof performance, and is a high-quality material for building decoration and furniture manufacture. Although the patterns of the scientific and technological veneer are simulated by a computer, the veneer has unique texture, texture and color of wood, and the veneer is various in types, is simulated to be lifelike, and can be produced in batches, namely, the veneer is red beech, sapelli, ebony and rosewood. The scientific and technological veneer as a new generation of decorative material can be used for decorating curved surfaces, special-shaped surfaces and indoor walls besides artificial boards and furniture decorations. In the embodiment, the composite wood or the flame-retardant wood is adopted, so that the whole material has good fireproof performance and waterproof and moistureproof functions.
