I believe everyone is familiar with anti-corrosion wood flooring. It is often used in the decoration of outdoor terraces. Compared with the coldness of ceramic tiles, it can give people a comfortable, comfortable, and natural feeling.

The difference between preservative wood and ordinary wood floors is that it can withstand wind, rain, and sunlight and effectively prevent insect and other microorganisms’ destruction. Even in harsh environments, it is easy to care for and has long-lasting durability.
So why is it embalming? The reason is that the main process of anti-corrosion wood is to soak the wood in the potion. Due to the potion’s immersion, the surface wood’s physical properties have changed, and the anti-corrosion, moisture-proof, and mildew-proof have been greatly improved. And because these potions contain copper oxide, the preservative wood generally appears green or blue-green.
Is the medicine soaked in environmentally friendly? Is it harmful to the human body? These problems mainly depend on the added preservatives. There are currently two main types:
One is CCA anti-corrosion treatment; the main component is chromate copper arsenate, which contains trace amounts of arsenic and heavy metal cadmium, which will cause harm to the human body.
The other is ACQ anti-corrosion treatment; the main component is quaternary ammonium copper, and the main components are quaternary ammonium salt and copper oxide; the toxicity is relatively low, and the environmental protection is good.
Although the preservative wood produced by the current manufacturers has environmental protection certification, due to the long-term volatilization of the agent, it will still cause harm to people in a closed environment. Therefore, whether it is CCA or ACQ, do not use it indoors. On the contrary, it is most suitable to use it outdoors. Due to good ventilation, there is no damage to physical health.
So let’s talk to you about three related knowledge points of anti-corrosion wood:
Classification and advantages of preservative wood:
1. Russian camphor pine: small deformation coefficient, vertical texture, high-cost performance.
2. Nordic red pine (also known as Finnish wood): strong nail grip, high density, and good strength.
3. southern pine (also known as yellow pine): good corrosion resistance, high abrasion resistance, and sufficient toughness.
4. Pineapple lattice: natural anti-corrosion, good stability, good resistance to insects and ants.
5. Citrus pine: strong nail grip and good structure.
As for outdoor wood flooring, the most used at present is camphor pine, which has good stability and high-cost performance.
