Pressure treatment of Sitka spruce lumber with ammoniacal copper zinc arsenate or chromated copper arsenate
1993
Lebow, S.T. | Morrell, J.J.
Air-seasoned Sitka spruce was treated with ammoniacal copper zinc arsenate (ACZA) or chromated copper arsenate (CCA) at 11 commercial plants. Preservative retention and penetration were greater with ACZA treatments. All but 2 of 14 charges treated with ACZA met the American Wood Preservers' Association specifications for treatment of lumber in ground contact. Despite incising, none of the CCA treatments reached the required depth of penetration, and only 3 of 15 CCA charges achieved the desired chemical loading.
