    摘要: Chromated copper arsentate wood preserving solutions in which the ratio of hexavalent chromium to trivalent chromium in the solution is between about 4.0:1.0 to about 1.0:1.0 give improved penetration into the wood, better retention of preservative in the wood, and improved stability of the treating solution. The solutions contain an acid to maintain the required pH, prevent corrosion, and further improve the solution stability.
