Yunnan Dali anticorrosive wood manufacturers tell you why there is a color difference in the board?
Answer: Because the CCA or ACQ antiseptic agent has been impregnated, the chemical composition agent causes the surface to be green. The board is divided into heartwood and sapwood. Heartwood belongs to natural anticorrosion, and green is mostly sapwood. Anticorrosive treatment is mainly for sapwood. And the chromatic aberration will gradually disappear due to long-term use outdoors.
