How much do you know about preservative wood? What are the characteristics of preservative wood?


   Artificial preservative wood is a kind of wood that is made of ordinary wood by artificially adding chemical preservatives to make it anti-corrosion, moisture-proof, anti-fungal, anti-insect, anti-mildew, and waterproof. It is often used in outdoor flooring, engineering, landscape, anticorrosive wood flower stand, etc., for people to rest and appreciate the natural beauty. It is an ideal material for outdoor flooring, garden landscape, wooden swing, entertainment facilities, wooden plank road, etc. It is favored by garden designers However, with the development of science and technology, anti-corrosion wood has been very environmentally friendly, so it is often used in interior decoration, flooring and furniture. Interior decoration designers also like anti-corrosion wood very much.


   The specific performance characteristics of anticorrosive wood are as follows:


   1. Compared with other woods, anticorrosive wood has the advantages of high density, high strength, and good nail holding power.


   2. The anticorrosive wood has clear texture and very good decorative effect.


   3. It can resist the harsh outdoor environment, can prevent and reduce decay, resist the erosion of termite pests and anti-fungal organisms.


   4. It can prevent the parasitic of aquatic parasites, and it is relatively easy to maintain, and the materials used are environmentally friendly. Therefore, compared with other raw materials, anti-corrosion wood is economical, durable, and beautiful.


  But at the same time preservative wood also has the following disadvantages:


   1. There is a certain color difference. Natural trees have their own color differences. Anticorrosive wood itself is a tree, which is naturally unavoidable.


   2. Easy to crack and deform. Experts said that the deformation of wood is related to cracking and moisture content. The deformation of wood is caused by internal pressure, and the cracking of wood is due to new changes in the surface of the wood, but the root cause of the changes is that the moisture content inside the wood has changed.


   Common preservative wood can be divided into natural preservative wood and artificial preservative wood according to whether it has undergone chemical treatment. Natural preservative wood includes: merbau wood (commonly known as pineapple grid), balau wood, Canadian red cedar, etc. Artificial preservative wood includes: Russian pine, Nordic pine, American southern pine, and carbonized wood.
