The effects of tree position and silvicultural practices on treatability of Douglas-fir lumber

Creator:: Hong, Seungdo
Abstract:: In spite of the lack of accurate information about the treatability of western wood species with waterborne wood preservatives, consumption of these products continues to increase. Western wood species, notably Douglas-fir, are notoriously difficult to treat with waterborne systems, yet there is relatively little data on the effects of wood...

Controlling biodeterioration of western wood species with over- the-counter wood preservatives

Creator:: Newbill, Mark A.
Abstract:: Over-the-counter (OTC) wood preservatives can provide wood with both a moisture barrier and fungicidal protection against biodeterioration, yet there is little comparative data on the performance of these preservatives. In this study, the potential of various low-toxicity, OTC preservatives was evaluated on five western wood species, western red cedar (Thuja...

Controlling sapstain : trial of strong stain-preventive solutions on selected western softwoods in storage prolonged for 12 months

Creator:: Miller, Donald J. (Donald James) and Oregon State University. Forest Research Laboratory
Abstract:: Environmental restrictions have induced many sawmills to seek alternatives to pentachiorophenol (penta) and similar chlorinated phenols for controlling mold and fungal stains on green lumber during storage and shipment. For that purpose, ten alternative stain preventives were evaluated against a traditional penta product (Permatox 101) on studs of Douglas-fir [Pseudotsuga...

Controlling hardwood sapstain : trials of stain-preventive products on red alder lumber

Creator:: Miller, Donald J. (Donald James), Morrell, Jeffrey J., and Oregon State University. Forest Research Laboratory
Abstract:: Production of hardwood lumber (mostly red alder) has been a small but growing part of the forest products industry in the Pacific Northwest. In laboratory tests, Rodewod® 200 EC plus borax protected alder at nearly all levels tested. Eight other chemicals provided some protection at the highest level tested. Fungal-stain...

Natural durability of wood : a worldwide checklist of species

Creator:: Scheffer, T. C., Morrell, Jeffrey J., and Oregon State University. Forest Research Laboratory
Abstract:: Naturally durable woods have a variety of commercial uses. Natural resistance to decay has been evaluated in field and laboratory tests of wood from many species, but there are few places where commercial wood users can find comparative assessments of natural durability. In this report, previous studies have been used...

Service life of treated and untreated fence posts : 1996 post farm report

Creator:: Morrell, Jeffrey J., Miller, Donald James, Schneider, Philip F., and Oregon State University. Forest Research Laboratory
Abstract:: Untreated and preservative-treated fence posts were exposed in soil at a test site near Corvallis, OR. Several species, including western juniper and Osage-orange, showed exceptional natural durability. Preservative treatment generally extended the useful life of the posts, but the degree of protection varied with the chemical and the application method.

Pressure measurement in wood as a method to understand impregnation processes : conventional and supercritical carbon dioxide

Creator:: Schneider, Philip F.
Abstract:: Two approaches to improving wood treatability include the modification of pressure schedules during conventional liquid treatments and the use of supercritical fluids (SCFs). In both of these techniques, pressure differences are important for transporting materials into wood. The level of pressure and its change during SCF treatments are also important...

Vapor copper : a potential wood preservative

Creator:: He, Wenlong
Abstract:: This study seeks to determine the feasibility of utilizing one vaporizable copper compound - bis-[1- (dimethylamino)-2-propanolato] copper(II) (Cu(DMAP)₂ as a potential wood preservative. The synthesis of Cu(DMAP)₂ was conducted in accordance with a method developed by Buhro and Dingman, Washington University, St. Louis, Missouri. The yields of Cu(DMAP)₂ synthesis were...
