The Use of Buffered Amine Oxides to Penetrate Engineered Wood Products and Structural Panels

摘要

The use of buffered amine oxides, known commercially as the TRU-CORE~R Process is a novel, chemically-based technology for rapidly delivering globally accepted wood preservatives and insecticides deep into the core of wood and wood-based composites in awaterborne carrier. Protectant materials which can be utilized with the buffered amine oxide process include a variety of carbon-based fungicides and insecticides. An important feature of the buffered amine oxide process is its ability to completely penetrate wood species such as Douglas fir and SPF, which are generally considered to be refractory (very difficult to penetrate) and its ability to treat wood composites such as plywood, laminated veneer lumber (LVL), and oriented strand board (OSB) withoutimpairing their appearance or reducing their mechanical properties. Some of the basic characteristics of the buffered amine oxide process are presented along with data demonstrating its ability to treat several commercially important but normally difficult-to-treat wood composites with protectant materials such as the insecticide permethrin. These building materials, once treated, can meet key standards set by the building codes in many jurisdictions.
