Whats the difference between preservative wood and carbonized wood?

Now, let's explain the difference between the two

Antiseptic wood is a kind of wood which has the function of preventing the decay of fungi and biological invasion after special antiseptic treatment. Therefore, it is mainly used in outdoor or balcony terrace areas.

Carbonized wood is obtained by heat treatment at 180 ℃ ~ 250 ℃ with stable size and improved corrosion resistance. Because it is more environmentally friendly, it is generally used indoors and can replace the ecological board and finger board. By the way, the environmental protection degree of board: carbonized board > finger joint board > ecological board > particle board.

Carbonized wood is carbonized wood, which is treated by carbonization. Carbonized wood is divided into surface carbonized wood and deep carbonized wood.

1. The surface carbonized wood is roasted with oxygen welding gun, so that the surface of wood has a very thin carbonized layer. The change of wood properties can be compared with wood paint, but it can highlight the concave and convex grain on the surface and produce three-dimensional effect. The application is concentrated in crafts, decoration materials and aquarium can products. Also known as process carbonized wood, charcoal wood.

2. Deep carbonized wood is also called carbonized wood and homogeneous carbonized wood. It is a kind of wood that has been carbonized at about 200 ℃ by high temperature carbonization technology. Due to the destruction of its nutrient composition, it has better anti-corrosion and anti insect function. Due to the reorganization of its water absorbing functional group hemicellulose, the product has better physical properties. Deep carbonized anti-corrosion wood is a real green environmental protection product, although the product has anti-corrosion and anti insect performance, However, it does not contain any harmful substances, which not only improves the service life of wood, but also does not have any impact on human body, animals and environment in the process of production and waste treatment after use. Deep carbonized wood has nearly ten years of experience in Europe, and is the main replacement product after the prohibition of CCA preservative wood. Deep carbonized anticorrosive wood is widely used in wallboard, outdoor floor, kitchen decoration, sauna room decoration, furniture and many other aspects. However, it is not recommended for use in contact with water and soil.

The most direct way to identify the two is that the surface of the antiseptic wood is yellow green, and the surface of the carbonized wood is golden yellow to brown. In addition, because the immersion of the cross-section will not reach 100%, the color of the cross-section will be inconsistent when cutting the antiseptic wood. After cutting, the section of carbonized wood is the same color.
