This kind of wood is corrosion-resistant or slightly corrosion-resistant, and it is easy to carry out anti-corrosion treatment. It is fine and straight in texture, similar to Korean pine, and can be used instead of Korean pine. It is a kind of wood suitable for making port pile wood, but it must be subject to anti-corrosion treatment. After anti-corrosion treatment, it can effectively prevent the invasion of mold, termite and microorganism, effectively inhibit the change of moisture content of treated wood, and reduce the cracking degree of wood, So that the wood life can be extended to 40 to 50 years. Russia is extremely rich in Pinus sylvestris resources and is the main log import base of China's anti-corrosion enterprises. Camphor pine anti-corrosion wood is imported by Chinese anti-corrosion enterprises from abroad and produced by their own anti-corrosion treatment. The price is moderate. At present, it is popular in the Chinese anti-corrosion wood market. Therefore, we choose camphor pine as the base material.

1. Anticorrosive wood treatment process:

The vacuum pump pumps out the air in the tank (about -0.09mpa) → injects antiseptic and fills the tank with antiseptic liquid → discharges antiseptic and vacuumizes to remove excess antiseptic (about -0.09mpa) → pressurizes to make the antiseptic fully penetrate the wood (1.0-1.4mpa)

2. Does the liquid drying on the surface of the antiseptic wood mean that the antiseptic has been fixed?

The drying of liquid (preservative) on the surface of preservative wood does not mean that the preservative has been fixed. For the wood treated with CCA (copper, chromium and arsenic), it takes 4-6 weeks to fix CCA in cold winter (temperature lower than 5 ℃), and only 1-2 days in hot summer (temperature higher than 30 ℃). The fixation of CCA preservative in wood can also be accelerated artificially by putting it in a drying kiln for accelerated drying, also known as secondary drying. However, the drying speed should not be too fast, otherwise part of the preservatives will be released, causing air pollution and corrosion of the fans in the drying kiln.

3. Characteristics of wood preservatives

Security. (the wood preservative and the treated wood may cause poisoning to people and animals, and the possibility of environmental pollution and fire is small.)

Effectiveness. (wood preservatives must effectively prevent biological damage to wood.)

persistence. (1. The preservative is not easy to undergo chemical decomposition or muddy hair under normal temperature. 2. The corrosion resistance of the preservative or the water solubility of the preservative itself)

Economy. (the cheaper the raw materials of a preservative, the simpler and easier the preparation and manufacturing process, the lower the cost of the preservative and the more competitive it is in the market.)

4. What are the advantages of waterborne preservatives?

(1) Low processing cost. Because this kind of preservative uses water as solvent, the price of water is cheaper than that of organic solvent, and the source is abundant, so the treatment cost is lower than that of organic solvent preservative;

(2) After treatment, the wood surface is clean, generally without irritating odor, which does not affect the paint and gluing performance of the wood, and is suitable for the treatment of building materials;

(3) And will not increase the flammability of the wood.

5. Can spruce be treated with antisepsis?

The wood treated with anti-corrosion impregnation needs a certain chemical carrier (resin) to carry the anti-corrosion agent from the surface of the wood to the inner core of the wood. Because spruce has no such substance, even if it is treated with anti-corrosion treatment, the anti-corrosion agent will only be fixed on its surface, and will not penetrate into the wood, affecting the anti-corrosion performance of the wood
