A review of double-diffusion wood preservation suitable for Alaska.

Abstract

The Forest Service of the U.S. Department of Agriculture is dedicated to the principle of multiple use management of the Nation's forest resources for sustained yields of wood, water, forage, wildlife, and recreation. Through forestry research, cooperation with the States and private forest owners, and management of the National Forests and National grasslands, it strives-as directed by Congress-to provide increasingly greater service to a growing Nation. The U.S. Department of Agriculture (USDA) prohibits discrimination in all its programs and activities on the basis of race, color, national origin, age, disability, and where applicable sex, marital status, familial status, parental status, religion, sexual orientation genetic information, political beliefs, reprisal, or because all or part of an individual's income is derived from any public assistance program.

Alkylimidazolium Ionic Liquids Absorption and Diffusion in Wood

“…The uniform impregnation of wood materials is of great economic importance. Diffusion treatment with various chemicals can be viewed as a cost-efficient alternative to pressure impregnation, uniformly distributing water-borne preservatives (e.g., biocides, fire retardants, and moisture stabilizers) or resin precursors in wood, without the need for costly equipment [1,2]. In some instances, especially in hardwoods, diffusion treatment can be combined with pressure impregnation to improve the chemical distribution into the bulk of the material, ranging from green veneers to timber.…”
