1、 Carbonized wood is treated by high temperature carbonization, which is divided into surface carbonized wood and deep carbonized wood.
1. The surface carbonized wood is roasted by fire, so that there is a very thin carbonized layer on the surface of wood. The change of wood properties is similar to wood paint, and it can also highlight the concave and convex grain on the surface. The surface is similar to fire wood, producing a three-dimensional effect. The application is concentrated in crafts, decoration materials and aquarium can products. Also known as process carbonized wood, charcoal wood.
2. Also known as complete carbonized wood, homogeneous carbonized wood. It is a kind of high temperature carbonized wood that has been carbonized at about 195 ℃ ~ 212 ℃. Because of the destruction of its nutrient composition, it has good function of anti-corrosion and anti insect The semi cellulose of water absorbing functional group is recombined to make the product have better physical properties. The deep carbonized wood is a real green environmental protection product. The product not only has anti-corrosion and anti insect properties, but also does not contain any harmful substances.
It not only improves the service life of wood, but also does not use liquid medicine to soak in the production process. The waste disposal after use will not have any negative impact on human body, animals and the environment. 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 many aspects, such as interior exterior wall panel, outdoor floor, kitchen decoration, sauna room decoration, furniture and so on. So carbonized wood is a kind of real green building materials, environmental protection building materials. Here we are
2、 Antiseptic wood
It is a kind of wood that uses preservative to permeate and solidify the wood, so that the wood has the function of preventing the decay of rot fungi and microbial invasion. The efficacy of wood preservatives is mainly determined by their toxicity to harmful organisms. The greater the biological toxicity to wood, the stronger the preservative effect.
In general, the wood also needs to add other agents. First, it has antiseptic effect, and can enhance the rigidity, strength and durability of wood. It has antiseptic effect, termite resistance and fungus resistance. Therefore, it is mainly used for outdoor floor, sleeper and areas in contact with water and soil. For the sake of environmental protection, many projects now purchase antiseptic wood as sleeper and carbonized wood as floor. This is our preservative wood:
