Moisture content of logs under sprinklers
2000 - IRG/WP 00-40157
Logs are kept under sprinklers during storage for avoiding the development of sapstain fungi. According to literature, sapstain fungi do not develop if the moisture content is above 120%. It is supposed that, the water sprinklers maintain the log's moisture content above this value, but, very often, sapstain is found on sawn lumber cut from these logs. Logs are harvested and transported t...

Control de calidad eficiente de proteccion superficial sobre madera
2008 - IRG/WP 08-20397
Quality control is important to assure efficient protection of wood surfaces. When wood is exposed to the environment, it degrades due to weathering or environmental factors alone. Aging tests are utilized to test coating products. Quality control techniques are performed on exposed products according to standardized methods (NCh, ASTM, ISO, DIN, EN, FTMS, NTF, NBINT, or equivalents). Certified l...

A novel enzymatic treatment as a new approach for wood protection
2015 - IRG/WP 15-40701
Wood durability is a worldwide concern and most treatments tend to fail with regard to their efficacy along the time. Weather conditions lead to a loss of the treatment substances into the surrounding environment and, in consequence, generate also a public health concern. Recently, the employment of oxidative enzymes, such as laccases, has been proposed as a tool for lignocellulosics modificatio...
