The high demand for wood-based composites generates a greater use of wood adhesives. current industrial challenge is to develop modified synthetic adhesives remove harmful formaldehyde, and test natural scope the research included manufacturing high-density fiberboards (HDF) using binders such as polylactic acid (PLA), polycaprolactone (PCL), thermoplastic starch (TPS) with different resination...

Five kinds of commercially available wood-based composites (softwood plywood, hardwood plywood, medium density fiberboard, oriented strand board, and particle board, hereinafter abbreviated as SWP, HWP, MDF, OSB, and PB, respectively) post-treated with alkaline copper quat (ACQ) and copper azole (CA) were exposed to decay and subterranean termite activity under protected above-ground conditions...

The objective of this study was to determine the effects of some boron compounds, which have fire retardant properties, as well as melamineurea-formaldehyde (MUF) resins having different melamine contents (10%, 15%, and 20%) on some physical and mechanical properties of medium density fiberboard (MDF) panels. It was found that the water absorption (WA) and thickness swelling (TS) of MDF panels ...

Humidity is one of the main environmental factors affecting the emission rate and key parameters of formaldehyde and volatile organic compounds (VOCs) from building materials. Meanwhile, the initial emittable concentration (Cm,0) is proved to be the most sensitive key parameter to the emission behaviours. However, there is no report on the relationship between humidity and Cm,0. In this paper, ...

Equilibrium moisture content (EMC) as a function of relative humidity (RH) was measured in oriented strandboard. particleboard, medium-density fiberboard, hardboard, high pressure laminates, and solid wood. The measurements were made in both adsorption and desorption at 2 9 2 . The EMCRH data were fit to Nelson's sorption isotherm. It was found that Nelson's model can be used to describe the ex...

Lightweight sandwich panels have been widely used for structural applications in the building and furniture industry. The advantages of using these materials comprise their high stiffnessand strength-to-weight ratios. A large variety of applied materials and a wide assortment of developed manufacturing methods allow a purposeful design tailoring of sandwich components and a usage of different m...

Occupational exposures to wood dust have been associated with an elevated risk of sinonasal cancer (SNC). Wood dust is recognized as a human carcinogen but the specific cancer causative agent remains unknown. One possible explanation is a co-exposure to; wood dust and polycyclic aromatic hydrocarbons (PAHs). PAHs could be generated during incomplete combustion of wood due to heat created by use...

Research results are presented for two studies which use the common statistical method of decision trees. First, regression trees of the internal bond (IB) of 0.750” medium density fiberboard (MDF) identified significant regressors (α < 0.05) as “refiner steam pressure” which interacts with “press start control” and “dry fuel bin speed.” The highest IB (mean = 151 psi) occurred with “refiner st...

Extensive research has been carried out on the thickness swell (TS) behavior of different types of wood composite panels. Of particular interest, studies investigating layer TS behavior have been carried out by Wang and Winistorfer (2003, 2001, 2000), and Xu and Winistorfer (1995a and 1995b). Results from these studies clearly indicate that the majority of TS in wood composite panels, such as m...
