The method of wood preservation treatment How to preservative treatment of wood

1, chemical preservation: refers to the addition of wood preservatives, the use of an insoluble water-based preservative, in a closed vacuum tank on the wood pressure at the same time, the preservative into the wood, so as to achieve the effect of inhibiting the propagation of wood-rotting bacteria.

2, natural preservation: refers to not add wood preservatives, reduce the moisture content of the wood, usually moisture content of 18% below the wood decay bacteria will not be able to reproduce, the wood is placed in a ventilated place to avoid moisture.

3, hot and cold tank preservation: put the wood into the hot solution heating, according to the principle of thermal expansion and contraction, the wood will produce pressure differences within the wood, can overcome the resistance to penetration, and so the internal pressure of the wood is greater than the atmospheric pressure, immediately put the wood into a cold tank, the air inside the wood is cold is contracted, thus generating a negative pressure, so that the cold liquid is very easy to get into the wood, so as to achieve the purpose of anticorrosion.
