Medicine content of Qingdao antiseptic wood

When chemically treating Qingdao anticorrosive wood, preservatives need to be used, and the agent penetrates into the wood by means such as high-pressure heating. The NTRA EU standard is a chemical content of 12 kg per cubic meter of preservative wood. The sapwood part of the tree can be completely saturated with high-pressure treatment. The core part of the tree contains wood glue oil, so the antiseptic agent cannot penetrate, but the wood glue oil itself has antiseptic property, so the antiseptic degree of Qingdao antiseptic wood is in compliance with the standard.
