| titleOfInvention | Wood preservation method |
| abstract | PROBLEM TO BE SOLVED: To significantly improve the permeability of a drug to a hardly injectable tree species, particularly to its heartwood, and to use the tree species to perform a preservation treatment of a quality exceeding JAS K3 standard. Provided is an improved method for preserving wood, from which lumber can be obtained. SOLUTION: The method for preserving wood according to the present invention is an aqueous chemical solution containing a quaternary ammonium salt having an antibacterial activity and a polyalkylene glycol and having a pH of 8 or less against hard-to-inject tree species such as bay pine. Preferably, a first step of reducing the pressure in the drug solution injection container to 0.08 MPa and holding it for at least 30 minutes, and a second step of increasing the pressure in the drug solution injection container to 1.2 MPa and holding it for at least 2 hours And pressurizing and impregnating means. |
