Consult carbonated wood preservative production methods, the need for more detail, thank you!
stage
3, mandatory heat treatment. In the kiln is increased to 185 ℃ to 230 ℃ this temperature layer, at this temperature for 24 hours.
4, cooling and moisture regulation. The last step is to use a water spray system to reduce the high temperature. Then, the moisture content is increased at a temperature of 80 ° C.
Carbonized wood preservative wood refers to the wood after high temperature (generally more than 180 ℃) carbonization treatment to achieve a certain degree of corrosion of wood.
Carbonated wood preservative production methods and processes are as follows:
1, the first wood into the anti-corrosion equipment, and then sealed, drained inside the air. And then vacuum pressurized CCA preservative into the wood inside, the purpose of vacuum pressure is to make the wood from inside to outside can absorb anti-corrosion potions, so as to achieve the effect of all-infiltration, so that the life of preservative wood will be more durable.
2, the temperature increases and the high temperature burns the kiln, which is raised at a rapid rate using heat and steam to a level of 100 ° C, which is continuously increased thereafter to 130 ° C for high temperature drying, where the water content is in the wood Almost nonexistent.
There are two kinds of surface carbonization and deep carbonization. I have to teach for a seven years, no one to teach.
