Abstract: Carbonized wood is used in many situations. According to the carbonization process and degree, it can be divided into two types: surface carbonized wood and deep carbonized wood. Both types of carbonized wood have the characteristics of ordinary carbonized wood. There are only certain differences in processing technology, material selection, characteristics, uses, etc. It does not necessarily mean which type of carbonized wood is better. The choice is mainly based on specific uses and actual needs to choose the right one. Let’s learn about the difference between surface carbonized wood and deeply carbonized wood. 1. What is the difference between surface carbonized wood and deep carbonized wood

Carbonized wood is wood that has been treated with high-temperature carbonization process. After treatment, a dense and hard carbonized layer will be formed on the surface of the wood, which can protect the wood. According to Depending on the carbonization process, carbonized wood can be divided into surface carbonized wood and deep carbonized wood. There are certain differences between them:

1. Differences in processing technology

Surface carbonized wood It uses an oxygen welding gun to grill, so that the surface of the wood has a very thin carbonized layer. The change in the properties of the wood is similar to that of wood paint, but what is better than paint is that it can highlight the uneven wood grain on the surface and make the wood grain three-dimensional. Effect.

The processing technology of deep carbonized wood is to perform short-term pyrolysis modification treatment on the wood at a temperature of 191-212℃ in an environment that blocks oxidation and hydrolysis reactions, which can improve the dimensional stability of the wood. Durability and other properties.

2. Differences in material selection

The commonly used materials for surface carbonized wood are Douglas fir, Scots pine, Scots pine, etc. Among them, Nordic pine itself has hard and tight wood and beautiful texture. The surface carbonized wood has better corrosion resistance than ordinary carbonized wood, the wooden structure is stronger and the decoration is better.

Deeply carbonized wood is mainly made from Scotch pine, Southern pine, and Finnish wood. Due to the particularity of the wood itself, the carbonized wood will also have special properties. For example, deep carbonized wood from Southern pine is not easy to It absorbs water, has low moisture content, does not crack, is resistant to moisture, and is not easily deformed. It is an excellent moisture-proof wood.

3. Differences in characteristics

Surface carbonized wood is safe and environmentally friendly, has good anti-corrosion and insect-proof functions, has no special smell, and has no side effects on connecting parts and metal parts.

Deeply carbonized wood is different from charcoal, dry wood, thermally modified wood, etc. It is an intermediate for activated carbon production. It not only has the function of activated carbon, but also retains the characteristics of wood. It is environmentally friendly, air purifying, and stable. Strong, corrosion-resistant, easy to process and many other features.

4. Differences in uses

Surface carbonization is widely used in outdoor wall panels, outdoor furniture, outdoor floors, outdoor wooden doors, wooden blinds, gardening sketches, interior decoration, swimming pools, parking garages, Roof exterior decoration, beach guardrails, outdoor swings, wooden houses and other fields.

Deeply carbonized wood is more suitable for indoor ceilings, interior wall gussets, background walls, outdoor floors, kitchen decoration, sauna room decoration, furniture and other areas.

2. Which is better, surface carbonized wood or deep carbonized wood?

Which one is better, surface carbonized wood or deep carbonized wood, is a question that many friends will have. Both are carbonized wood. It’s just that the carbonization process and degree are different, so should you choose surface carbonized wood or deep carbonized wood?

In fact, the choice between the two types of carbonized wood is not fixed. The choice is mainly based on specific uses and actual needs. If you want better and more stable performance, it is better to choose deep carbonized wood with a higher degree of carbonization. Good; if you prefer the aesthetics of wood, surface carbonized wood is more suitable.
