How do preservatives and antifungal agents treat wood?
As early as the 1970s, anti-corrosion wood has appeared. At that time, people only used the method of applying preservatives on the wood to achieve the effect of wood preservation. The anti-corrosion wood we are talking about now is to place the wood in a high-pressure container, extract the air from the wood, and press the preservative deeply into the wood's cells.
This process is a key step in preservative treatment. First, the physical process of injecting the preservative into the wood is realized, and at the same time, the chemical reaction process of some of the active ingredients of the preservative and the starch, cellulose and sugar in the wood is completed. It destroys the living environment of bacteria and insects that cause wood decay. The main preservatives include ACQ, CCA, etc., which are compounds containing heavy metal ions, but as people understand the environment and health, these agents will be replaced step by step.
Currently, unpreserved wood and wood products are susceptible to insect infestation and rot, and may only have a life span of 1-4 years when the wood is in contact with soil or water. The wood that has undergone preservative treatment is not only beautiful in appearance, but also strong, light in weight, and strong in processing performance. It can reach 50 years under normal maintenance, and the world can save billions of trees every year. And anticorrosive wood is also an environmentally friendly building material.
