Carbonized wood is called physical “antiseptic wood” or heat-treated wood. After carbonization, it can protect the wood itself from the influence of external environment such as wood decay fungi, insects and ants, thus effectively maintaining the characteristics of the wood itself.
There are two types of carbonized wood: surface carbonized and deep carbonized.What is the difference between the two? Next, we distinguish them from several aspects:
1.Different processing technology
Surface carbonization is done by using an oxygen torch to give the wood a thin carbonized layer on the surface, similar to paint, but at the same time it can highlight the wood grain on the surface and create a three-dimensional effect.
Deep carbonization is a short-term pyrolysis modification treatment of wood at a temperature of 180℃~250℃ in an environment that blocks oxidation and hydrolysis reactions in order to improve the stability, durability and other properties of the wood.
2.Appearance Difference
Surface carbonized wood: The surface is black or dark brown, while the inside still retains the original color of the wood, and the color inside and outside is inconsistent.
Deep carbonized wood: The overall color is relatively uniform, mostly dark brown to black brown, the color inside and outside is basically the same, and the surface of the wood has a light luster.
3.Different uses
Surface carbonized wood is widely used in handicrafts, gardening and other decoration materials, while deep carbonized wood is mostly used for indoor and outdoor wall panels, sauna room decoration, outdoor flooring, etc.
