Description

[0002] Wood impregnation pressurization technology, that is, soaking wood in a specific solution and making the solution penetrate into the cell wall and cell cavity of wood through pressurization, thereby forming a protective layer or reinforcing layer inside the wood. The core of this technology is to use pressure to make the solution quickly and uniformly penetrate into all parts of the wood, thereby achieving the desired modification effect. The impregnation solution usually includes resin, preservative, flame retardant, etc. These chemicals can inhibit the growth of fungi, bacteria and insects, prevent wood from rotting and being damaged, and improve the dimensional stability, mechanical strength and moisture resistance of wood.
