A New Copper Fixation Process

摘要

A patent-pending method of fixing ammoniacal copper preservative systems is described. During treating, the process forms basic copper carbonate in-situ (inside the wood) and leaching tests show low copper losses similar to those of micronized copperformulations. In addition, the reaction is rapid and the ammonia odor is eliminated. Efficacy of the treated wood against decay and termite attack is also the same as other copper formulations. The background, chemistry, and properties of the new processare given.
