How to maintain carbonized wood
1. Some chemical substances produced in the whole carbonization process of wood carbon carbonization machine are harmful, and simple preventive measures should be taken to reduce the risk. It is harmful that carbon monoxide is high in the whole process of carbonization. Therefore, when working near the kiln or pit, and preparing to unload carbon in advance when opening the kiln, be careful to give appropriate natural ventilation to release carbon monoxide. During the unloading period, the spontaneous ignition of hot wood carbon also caused carbon monoxide;
2. Because carbonized wood is solved in high temperature natural environment, the sugar content (methylcellulose) in wood dissolves at high temperature to produce monosaccharide, monosaccharide adheres to the surface of wood, with the increase of time, the surface is prone to decay, and the surface is dark brown or dark brown. In addition, the ability of digesting and absorbing bound water is not strong, but the ability of digesting and absorbing free water is strong. In order to alleviate this situation, three layers of paint can be applied on the surface of carbonized wood;
3. Because of the unique application in outdoor natural environment, carbonated wood will have cracks, small deformation and normal conditions, which does not harm the compressive strength of the structure. The general outdoor wood safety protection building coating is infiltrated. In wood chemical fiber, a protective film will be produced, which can reasonably block the corrosion of water on wood. The cleaning can be cleaned with general cleaning agent, and special tools can be cleaned with soft brush. One year to 1.5 years, do maintenance first; Special tips can be given when applying special wood water-based paint or oil soluble building paint: workers should clean and clean their hands before eating. Working clothes cleaning should not be cleaned with other clothes and trousers.
Common problems in application of carbonized anticorrosive wood
1. The grip force of carbonized and anticorrosive wood is lower than that of untreated wood. Therefore, it is highly recommended to use the first opening and then the installation of the nail hole to reduce and prevent the wood from cracking.
2. Carbonated anti-corrosion wood is not suitable for touching the natural environment of soil layer and water.
3. When carbonized anticorrosive wood is used outdoors, it is suggested to select UV wood oil to prevent the wood from fading in the long run.
The key to the quality standard of carbonized wood is that the equilibrium moisture content of wood is 3% lower than that of untreated wood, the dry shrinkage rate is lower than 5%, which is better than 7% of red teak.
