High-grade dissolving pulp was prepared from radiata pine by the pre-hydrolysis Kraft process. The effect of the P-factor in the pre-hydrolysis stage on the properties of wood chips was investigated. With an increasing P-factor, hemicellulose was selectively removed from wood chips, and the...

Introduction: Particle board production is based on the use of sawmill and remanufacturing residues; however, the availability of this raw material has decreased significantly due to its use as biomass for firewood fuel. Objective: To evaluate the effect of the replacement level of maize (Zea mays...

The aim of this research was study of polyurethane (PUR), isocyanate polymer emulsions (EPI) and melamine - urea - formaldehyde (MUF) adhesives, on the bonding properties of solid and hollow glulam beams of Pinus radiata. The thermomechanical analysis (DMA) of the adhesives was carried out to...

In order to study the flame retardant properties of silica sol and ammonium polyphosphate(APP), radiata pine wood was impregnated with APP, silica sol and their flame retardant under vacuum and atmospheric pressure; the weight gain, compatibilization rate, pyrolysis and combustion properties of the ...

Various factors, such as molecular weight (MW), reactivity, wettability, surface roughness, surface adhesion, interphase adhesion, and cohesion of adhesives, affect the adhesion strength of urea-formaldehyde (UF) resins when bonding wood. This study was conducted to understand the MW effects of UF...

A conventional stereo light microscope was used to image polished wood surfaces at cellular resolution over size scales of the growth ring or larger. Bandpass filtering and local area contrast enhancement were used to aid automatic image thresholding and binarisation. An estimate for the location...

The purpose of this paper is to investigate the influence of kiln temperature, relative humidity and wood moisture content on the content of acid and alcohol released in the drying process of high temperature kiln by studying the radiated pine sawn timber of 40 mm thickness. The drying temperature...

Understanding mechanisms of materials deterioration during service life is fundamental for their confident use in the building sector. This work presents analysis of time series of data related to wood weathering acquired at three scales (molecular, microscopic, macroscopic) with different sensors. ...

Cross-laminated timber (CLT) panels are commonly used in mass-timber multistorey constructions due to their prefabrication, construction flexibility, environmental credentials and weight-to-strength ratio advantages compared to competing building materials. However, the long-term durability and...

Charcoal derived from sustainable grown wood is a potential source of fuel and reductant for iron and steel making and a potential way to decrease the net CO₂ emissions from the steelmaking industry. However a modern charcoal making process is likely to be required to supply the iron and steel...
