Pinus sylvestris var. mongolica is the main wood used for anti-corrosion flooring in China. After anti-corrosion treatment, Pinus sylvestris var. mongolica has fine quality and straight texture, which can prevent the invasion of mold, termite and microorganism, inhibit the change of moisture content of treated wood, reduce the cracking degree of wood, make the outdoor anti-corrosion wood more durable and easy to use, and prolong the service life of anti-corrosion wood. Pinus sylvestris var. mongolica is mainly distributed in cool summer and cold winter with proper precipitation. It is distributed in Daxinganling of Heilongjiang Province, some mountainous areas to the west of Hailar of Inner Mongolia and the north of Xiaoxing'anling of China. Pinus sylvestris var. mongolica resources are very rich in Russia.
Vacuum / high pressure impregnation is the key step of wood preservative treatment. Firstly, the physical process of putting preservative into wood is realized. At the same time, the chemical reaction process of some preservative components with starch, cellulose and sugar in wood is completed, which destroys the living environment of bacteria and insects that cause wood decay, To improve the outdoor preservative properties of wood. In addition, the chemical reaction between preservative components and starch, cellulose and sugar in wood was also completed. Further destroy the living environment of bacteria and insects that cause wood decay. Natural air drying natural air drying requires air drying in the place where the wood is actually used. This process is to adapt to the changes of wood cell structure caused by the changes of outdoor open-air wood floor and outdoor special anticorrosive wood floor due to the changes of environment, so as to make it fully fixed in the gradual process, so as to avoid the changes in the use process.
