The Rubber Ruler: Continuous measurement of dimension changes in wood panels
1994 - IRG/WP 94-20033
A new application for a linear transducer called Rubber Ruler was developed. Rubber Ruler provides a simple and reliable method for continuous monitoring of dimension changes in wood panels. This paper presents the methodology. Results of priliminary experiments designed to simulate the movement in wood panels are also discussed....

Dimension of lysimeters and the evaluation of the migration of wood preservative components in soil
1996 - IRG/WP 96-50065
In the past, investigations concerning the migration behaviour of wood preservatives were made to a minor extent and no uniform methods of test exist. The migration behaviour of CFB was determined using 5 lysimeters of different dimension. The results of the migration and distribution of the anions in the soil showed considerable differences between both ions. Approximately the whole quantity of c...

Development of wood retification process at the industrial stage
1998 - IRG/WP 98-50101-16
Wood is a natural composite material which exhibits outstanding properties from the technical as well as from the ecological point of view. However, it is an anisotropic, hygroscopic material sensitive to biological attacks. We have to stabilise and preserve it if we want to ensure its market shares faced with competing synthetic material, whilst taking the new environmental rules into account.

Influence of different resin treatments on the dimension stability of wood
1997 - IRG/WP 97-40090
The dimension stability of wood is considered to be an important contribution to its durability and its performance in practice. A number of different treatments have been developed to improve the dimension stability of wood. One applied method is the treatment of wood with monomers or resins. The application of appropriate impregnation conditions seemed to be essential to enhance the efficiency o...

Effect of post-treatment drying schedule on the modulus of elasticity of CCA-treated southern pine dimension stock using nondestructive methods
1987 - IRG/WP 3413
This paper describes the results from the nondestructive testing for modulus of elasticity (MOE) of southern pine (Pinus sp.) 2 x 6's treated with chromated copper arsenate and redried using three commercial kiln schedules. The data indicate that redrying CCA-treated southern pine dimension stock treated to above-ground retentions (4 kg/m³) has no deleterious effect on the MOE, regardles...

Termite baiting system: A new dimension of termite control in the Philippines
2007 - IRG/WP 07-10608
The performance of a baiting system and efficacy of an insect growth regulator (IGR), chlorfluazuron, was evaluated against three economically important species of subterranean termites in the Philippines i.e., Coptotermes vastator Light, Microcerotermes losbañosensis Oshima and Macrotermes gilvus Hagen. Preliminary tests were conducted on secondary nests of M. losbañosensis and mounds of M. gil...

Properties of thermal modified wood of Pinus pinaster, Pinus radiata and Pinus sylvestris from Galicia, Spain
2024 - IRG/WP 24-30800
This paper provides the results of a research about the properties of thermal modified wood of maritime pine (Pinus pinaster Ait.), radiata pine (Pinus radiata D. Don) and Scots pine (Pinus sylvestris L.) from Galicia, Spain, thermal treated in the industrial vacuum-heat autoclave plant of FINSA group in Galicia, Spain. These three pine wood species are used in different solid products but due the...
