Preservative wood is a kind of wood that can prevent the decay of fungi and biological invasion after the preservatives are used to penetrate and solidify the wood. It is an indispensable natural resource in human production and life. It is deeply loved by people because of its excellent visual, tactile, auditory and humidity control properties.
However, for wood, the introduction of biological characteristics, it is inevitable that the new type of wood is vulnerable to bacteria, insects, wood decay and other problems. There are two kinds of common preservative wood in China: Pinus sylvestris var. mongolica and Pinus densiflora. The anti-corrosion wood of Pinus sylvestris var. mongolica is mainly treated by imported logs in China, most of which are treated by CCA.
Nordic Pinus densiflora anti-corrosion wood is imported from abroad and sold directly in China. It is treated with ACQ and is usually called "Finnish wood". People are used to call antiseptic wood Finnish wood. In fact, this is wrong, and it is easy for people who don't understand antiseptic wood to misunderstand it.
The main method of wood preservative treatment in the world is to use a water-based preservative which is not suitable for dissolving, put pressure on the wood in a closed vacuum tank, and at the same time, put the preservative into the wood fiber. After pressure treatment, the wood is more stable. Preservatives can effectively prevent the damage of mold, termite and insects.
Therefore, the treated wood has excellent corrosion resistance for long-term use in outdoor harsh environment When installing, you don't need to add any protective coating, so the anti-corrosion wood has anti-corrosion effect and certain protection. If consumers are not very satisfied with the color of the purchased wood, it is recommended to use oil-based or water-based coatings when they need to change the treatment. In this way, the performance of the two coatings can coexist and will not cause damage to the wood.
