Measuring Method of Formaldehyde Emission for Plywood

Journal of the Korean Wood Science and Technology, 2010
합판의 경우에는 제조 시 접착제가 각 단판의 전체 면에 도포되는 것이 아니라 접착 면에만 도포되므로 접착층을 따라서 접착제가 분포하게 된다. 따라서 섬유판이나 파티클보드의 경우와는 달리 전체 표면을 통하여 포름알데히드가 방산되지 않고 접착층을 따라서 방산된다고 판단되어진다. 따라서 기존의 KS M 1998-4 : 2005 방법으로 포름알데히드방산량을 측정하는 방법이 적절하지 않을 수도 있다고 판단되었다. 이에 본 연구에서는 동일한 조건에서 제조한 합판을 4가지 측정 조건에 따라 포름알데히드방산량을 측정하여 이들의 상관관계를 검토하였다.

Urea–Formaldehyde Synthesis with Kraft Lignin Nanoparticles and Effects on Formaldehyde Emissions

Processes
To seek improvements in the quality and sustainability of adhesives for bonding wood, the objective of this work was to use pine and eucalyptus kraft lignin nanoparticles in the synthesis of urea–formaldehyde adhesives. The rheological properties, shear strength of glued joints and formaldehyde emission reduction were evaluated.

Formaldehyde barrier efficiency of melamine impregnated paper and melamine edge-banding tape surfaced particleboard and MDF

Acta Silvae et Ligni, 2018
Particleboard and MDF are the most usable materials for furniture production, where emission of formaldehyde should be as low as possible. In order to improve aesthetic properties of particleboard and MDF they are covered with appropriate surfacing ...

Ozarks Isoprene Experiment (OZIE): Measurements and modeling of the "isoprene volcano'' [PDF]

, 2005
The Ozarks Isoprene Experiment (OZIE) was conducted in July 1998 in Missouri, Illinois, Indiana, and Oklahoma. OZIE was designed to investigate the presumed strong isoprene emission rates from the Missouri Ozarks, where there is a high density of oak ...

Development of phenol-formaldehyde resin with low formaldehyde emissions that respects LEED certification [PDF]

International Wood Products Journal, 2014
AbstractIn the last years, production of particleboards with good overall performance and very low formaldehyde emission has been a challenge to wood based panels (WBP) industry, mainly since the re-classification of formaldehyde by the IARC (International Agency for Research on Cancer) as ‘carcinogenic to humans (Group 1)’.

An improved mechanism-based model for predicting the long-term formaldehyde emissions from composite wood products with exposed edges and seams

Environment International, 2019
Emissions of formaldehyde from building materials and furniture can cause adverse health effects. Traditional models generally only consider emissions as a physical process that can be characterized by three key parameters: the initial emittable ...

Quality of Plywood Bonded with Nanolignin-Enriched Cardanol-Formaldehyde Adhesive

Fibers
Cardanol is a derivative of cashew nut shell liquid (CNSL) and has the potential to be used when developing adhesives for wood boards. Adding nanostructures to adhesive can increase its bonding and reduce formaldehyde emission.
