Classification and use of carbonized wood
Classification
According to the performance and application of the product, carbonized wood can be divided into two categories: indoor use and outdoor use. In addition to the requirements for appearance quality, the former mainly requires dimensional stability. The tangential swelling and drying shrinkage of the wood is required to be 6-8%, and its corrosion resistance level is required to be grade Ⅲ—slight corrosion resistance; the latter, in addition to In addition to the requirements for appearance quality, the main performance requirement is biological corrosion resistance, and its corrosion resistance level is required to be level II—corrosion resistance. In addition, the chordwise swelling and drying shrinkage of wood are required to be 5-6%.
The current tree species used in the manufacture of carbonized wood in Europe: mainly European scabbard pine (about 39%), spruce (about 43%), followed by birch (accounting for 8%), poplar (5%), and a small amount of larch , alder, beech, etc.
At this stage, the main tree species of carbonized wood in China are: sylvestris pine, hemlock, fir, ash, oak, maple birch, lotus wood, camphor, and jade stamen.
Uses of carbonized wood
Uses can be divided into two categories: indoor use and outdoor use.
Mainly used indoors: interior decoration, furniture, doors and windows, wall panels, floors, wooden structures and floors of sauna rooms, etc. Especially in the new residential buildings in northern my country, there are more and more heated floors. In the past, solid wood floors could not be used due to the dimensional stability. The release of formaldehyde from the adhesive layer of laminated and laminated floors causes indoor air pollution, which is a very difficult problem. Carbonized wood has good dimensional stability and can be used for geothermal floors without environmental pollution.
Outdoors are mainly used for: house exterior wall panels, garden furniture, light wood components for playgrounds, open floors or decks, pastoral architectural sketches, etc. Due to the increased brittleness of carbonized wood, it is not recommended for use in heavy wood structures.
Carbonized wood is a new product. It has not been produced and promoted in China for a long time, but because of its good dimensional stability and corrosion resistance, beautiful color, simple and elegant, and environmentally friendly, it does not need to add any chemicals, so it has been Favored by consumers. As consumers' understanding of it continues to deepen, it is believed that carbonized wood will be more and more widely used at home and abroad.
