10–1 Adhesive bonding of wood plays an increasing role in the forest products industry and is a key factor for efficiently utilizing our timber resource. The main use of adhesives is in the manufacture of building materials, including plywood, oriented strandboard, particleboard, fiberboard, structural composite lumber, doors, windows and frames, and factory-laminated wood products. Adhesives a...

Wood is a renewable material that can store biogenic carbon, and waste wood be recycled to recover bioenergy. The amount of energy recovery from the vary depending on type its chemical structural properties. This paper will analyse life cycle environmental impact wood, starting production stage. These are cradle-to-cradle systems, excluding use phase collection phase. types considered in curren...

In this study the production of particleboard using two fast growing tree species viz., Eucalyptus tereticornis and Melia dubia Urea Formaldehyde as adhesive. This experiment was conducted in Centaury plywood industry, Chennai. The physical mechanical properties were assessed for suitability production. Based on wood, Particleboards produced (100%) raw material. Physical Mechanical both particl...

this study was aimed to investigate the bending moment and stress (inner and outer corners) in lshaped biscuit joint made of solid wood, particleboard and medium density fiberboard (mdf). for this purpose, l-shaped joints made of beech and fir, particleboard and mdf by biscuit size numbers of 0 (47×15×3.8 mm), 10 (53×19×3.8mm) and 20 (60×23×3.8mm). bending moment and stress carrying capacity of...

In the triple helical structure of collagen proposed by RAMACHANDRAN and co-workers1, 2 (see ref. 2 for earlier references), there are two N H . . . 0 hydrogen bonds for every three residues in each chain. In the modification of the RAMACHANDRANKARTHA structure proposed by RICI~ A N D C R I C K a, the three chains are pushed slightly farther apart from their positions in this two-bonded structu...

One-step microfluidic approach in which interfacial complexation of hydrogen bonding polymers is utilized to prepare pH-responsive microcapsules presented. Using water-in-oil-in-oil-in-water (W1/O1/O2/W2) triple-emulsion droplets as templates, it shown that polymeric with an aqueous core and a shell consists two complementary polymers, poly(propylene oxide)(PPO) poly(methacrylic acid)(PMAA), ca...
