Treating Eucalyptus tereticornis wood with boron: Optimizing treatment conditions
2005 - IRG/WP 05-40309
Even though Eucalyptus tereticornis wood is suitable for small timber purposes, being non-durable, it needs to be treated with preservative chemicals. As it is a heavy, hard and difficult to treat species, the possibility of using diffusible boron compounds was investigated. The present study explored the effect of impregnation conditions such as treatment schedule, concentration of treatment solu...

Optimun storage period for the boron diffusion treatment of rubber wood
1996 - IRG/WP 96-30121
The study determined the maximum thickness of rubber wood that can be diffusion treated and the effect of diffusion storage period on the distribution of chemicals in treated wood of various thicknesses. Wood of thickness up to 50 mm can be easily diffusion treated with 10% boric acid equivalent (BAE) solution to adequate loading of chemicals. The optimum diffusion storage period to get uniform an...

Economical schedule for boron treatment of rubber wood: Pilot plant investigations
1993 - IRG/WP 93-40002
An economical treatment schedule (15 minutes initial vacuum of 85 kPa; 15 minutes pressure of 1000 kPa; 5 minutes final vacuum of 85 kPa) was arrived at for treating air-dried rubber wood (Hevea brasiliensis) in a pilot plant cylinder. Treating with 3% BAE (boric acid equivalent) solution resulted in a dry salt retention of 13.1 kg/m³. Also, the study showed that green rubber wood can be treated ...
