发明名称 STABILIZATION OF WOOD PRESERVATIVE SOLUTIONS AND PRESERVATION OF WOOD BY SUCH SOLUTIONS
摘要 A wood preservative solution comprising water, hexavalent chromium, copper and arsenic can be stabilized against precipitation by the addition of fluorine ion, thereby enhancing the useful life and safety of the solution. Fluoride salts like cerium fluoride, sodium fluoride and calcium fluoride are suitable sources for fluorine ion in such a solution. Wood treated with the preservative solution displays increased penetration, distribution and retention of chromium, copper and arsenic.
