Characterization of Phenol Formaldehyde Adhesive and Adhesive-Wood Particle Composites Reinforced with Microcrystalline Cellulose

Atta-Obeng, Emmanuel (2011-07-25)

The use of lignocellulosic materials as reinforcement in polymer adhesives has increased considerably over the past few years. Lignocellulosics, also known as natural fibers are more attractive to use compared with synthetic ...

Chemometric Modeling of the Structural Integrity, Chemistry and Bioenergy Potential of Elite Loblolly Pine Families and Forest Biomass

Acquah, GIfty (2016-12-12)

Pinus taeda L. (loblolly pine) is the most economically important tree species in the USA. With 30 million acres in plantations in the southern United States alone, it accounts for over 50% of the standing pine volume of ...

Crosslinked Polymers from Pyrolysis of Lignocellulosic Biomass

Barde, Mehul (2018-10-23)

Present research is aimed at the development of crosslinked polymers from biomass pyrolysis oil. Crosslinked polymers are high performance materials employed in a wide range of applications and are most commonly derived ...

Defatted Soy Flour Substitution in Phenol Formaldehyde and Methylene Diphenyl Diisocyanate Wood Adhesives and their Curing Kinetic Behavior

Hand, William (2018-04-27)

Composite wood products are manufactured utilizing reconstituted cellulosic material formed with thermosetting adhesives, primarily adhesives made from non-renewable materials. Natural wood adhesives, or bio-adhesives, had ...

Development and validation of a Paper-based analytical device (PAD) for formaldehyde detection and its utilization in wood composites emissions

Garcia, Jose (2022-05-06)

Volatile organic compounds (VOCs) are caused by different sources, including non-fully cured adhesives used to bond the pieces of wood in the fabrication of wood composites. N on-cured Phenol-Formaldehyde resins represent ...

Hemicelluloses extraction and nanocellulose addition as a partial replacement for non-renewable adhesives in oriented strand board.

Hornus, Marina (2019-04-16)

Oriented strand board (OSB) is an engineered wood product used for building wood-based structures (e.g., walls, floors, ceilings, furniture). This composite is manufactured with small pieces of wood (strands) linked together ...

Interfacial behavior of lignin containing cellulose nanofibrils (LCNFs) and their impact on composite materials

Iglesias, Maria Celeste (2021-12-02)

Over the last decade, the utilization of nanocellulose for novel applications has positioned this renewable source as a promising alternative substitution for petroleum-based materials. In an attempt to utilize and incorporate ...

Modification and characterization of liquefied biomass-based epoxy resin

Nan, Wei (2013-07-18)

With the increasing requirement of biomass composites, people have paid more attention to the increasing use of synthetic adhesives, which require petroleum-based resources. Talking about petroleum-based resources, the ...

Monitoring Moisture Content and Mass Flow of Wood Chips Using Electrical Capacitance Tomography

Pan, Pengmin (2014-12-10)

Woody biomass is currently sold on a wet basis, a system that works because moisture content of harvested trees normally uctuates within a narrow range and wood from multiple sources can be considered a uniform product. ...

New approach on Phenol-Formaldehyde resins for Wood Composites

Cardozo, Alejandro Ariel (2020-07-30)
