Intumescent coating was studied relative to the fire performance of naillaminated timber. Three NLT specimens were coated with three different intumescent coating thicknesses (1, 2, and 3 mm) in even-numbered laminae and compared to uncoated NLT specimens. As a result of the coating, the internal...

This study was conducted to confirm the effects of combined radio-frequency/vacuum-press (RF/VP) drying on the strength properties of Japanese larch board. The strength properties of board dried at RF/VP was evaluated in comparison with conventional kiln, high-temperature, hot-air/vacuum dried, and ...

Many countries, including South Korea, decided to suspend the inclusion of harvested wood products in their Nationally Determined Contributions, as part of the carbon inventory, in 2016. The inclusion of harvested wood products in the national greenhouse gases inventory must ensure the accuracy of...

Biological damage due to material characteristics and climatic change poses serious threats to wooden cultural heritage objects in Korea. This study is a preliminary survey for the preparation of a conservation/management plan for Janggyeongpanjeon (depositories of the Tripitaka Koreana...

The flame retardancy, such as carbonized length and area, of four plank type wood products by the spreading concentration and impregnation time of flame retardant were measured according to standard of the Nation Fire Agency in Republic of Korea. To measure the flame retardancy, Korean pine...

Wood drying is the most time- and energy-consuming process in the wood industry. Without proper optimization of the drying process, an attempt to reduce drying time and energy by accelerating the drying rate might easily result in the creation of various defects within the kiln-dried lumber. To...

The objective of this study was to assess the wood properties and drying characteristics of sawtooth oak (Quercus acutissima Carruth.) to determine the potential for the extension of its use in South Korea. The annual rings, latewood ratio, dimensions of the vessels, density, and shrinkage of...

To realize the infinite possibilities of materials derived from wood, it is necessary to overcome the weak moisture stability of wood. Thus, the development of an eco-friendly hydrophobic coating agent is essential, and of these, woody biomass-based materials are strongly attractive as coatings. In ...

Ecosystem services (ESs) play an important role in improving human well-being. This study identified the changes in people's perceived importance of forest ecosystem services (FESs) due to changes in forest use caused by the coronavirus disease-19 (COVID-19) pandemic. We measured the changes in...

The pitch contained in thermomechanical pulp (TMP) negatively affects paper quality, pulp, and the papermaking process. Serious pitch and stickies problems may occur in paper recycling processes. In this study, the effects of chemicals used to control the pitch in the TMP process were compared. The ...
