First, natural preservative wood: such as red cedar in Canada and the United States, Balamu in Indonesia and Malaysia, this natural, untreated, natural preservative wood is expensive, but also the most environmentally friendly material.

Secondly, the current artificial preservative wood species mainly include Pinus sylvestris var. sylvestris, which has a fine tree texture and straight texture. The quality is not as good as that of imported wood, but the price is moderate. It is currently popular in the Chinese national defense rot wood market. The southern pine, which is popular in the world, grows in the south of the United States. Due to its special cell arrangement, preservatives can reach heartwood and have excellent bending resistance, it is most suitable for use as a structural framework. The European-loving Nordic red pine has the characteristics of slender and straight, woody and strong, and the wood texture is clear and beautiful. With low resin and porous structure, it is very suitable for anti-corrosion soaking treatment and is a good material for making anti-corrosion wood.

Third, the early preservatives used CCA-C and B wood preservatives. Although this kind of preservative has certain toxicity, it is less harmful because it is only used outdoors. Nowadays, ACQ-D, C, B wood preservatives have emerged. The anti-corrosion wood processed by this preservative is environmentally friendly, and its toxicity is greatly reduced. You can buy it with confidence.

Fourth, test the effect of anti-corrosion treatment, intuitively observe the surface finish of the anti-corrosion wood, the surface of the agent is not well treated with impurities such as powder, and the color is not uniform. In addition, you can directly open the anti-corrosion wood to see the treatment depth, a good treatment can reach the heartwood, at least to reach a depth of 1 cm, so that the anti-corrosion effect will be good.

Fifth, in addition, pay attention to check whether the surface of the wood has any thrift, crack, deformation and so on. Thrift is not only affecting the beauty of wood, but also an important channel for eroding wood such as bacteria and insects. Cracks and deformations are mainly caused by poor drying treatment. The wood treated with anti-corrosion treatment generally has a moisture content of less than 18% and will not crack or deform when placed in the air.

Sixth, although the anti-corrosion wood has many impressive features, it will appear discolored, blackened and cracked due to its solid wood material. Therefore, in the later use, it is necessary to regularly protect the surface of the anticorrosive wood with wood wax oil to enhance the waterproof and antifouling performance of the surface.
