In order to figure out the use of compression in the wood preservation aspect, the authors compared the compressed wood samples pretreated with hot water bath or water spraying and compressed preservative-treated wood, which was treated with ammine copper quat-type D preservative solution. The liquid absorption and recovery rate of compression deformation of the compressed wood were determined, as well as the surface hardness, distribution of density and CuO retention in the thickness direction of CPW.
