Formaldehyde Emission in Micron-Sized Wollastonite-Treated Plywood Bonded with Soy Flour and Urea-Formaldehyde Resin

open access: yesApplied Sciences, 2020
Soy flour was partly substituted for urea-formaldehyde (UF) resin with different content to investigate its effect on formaldehyde emission in three-layer plywood panels. In each square meter of panels, 300 g of resin was used (wet weight basis of resin).

Seasonal and interannual variability of North American isoprene emissions as determined by formaldehyde column measurements from space [PDF]

open access: yes, 2003
Formaldehyde (HCHO) columns measured from space by solar UV backscatter allow mapping of reactive hydrocarbon emissions. The principal contributor to these emissions during the growing season is the biogenic hydrocarbon isoprene, which is of great ...

Sol-gel based sensor for selective formaldehyde determination [PDF]

open access: yes, 2010
We report the development of transparent sol–gels with entrapped sensitive and selective reagents for the detection of formaldehyde. The sampling method is based on the adsorption of formaldehyde from the air and reaction with β- diketones (for ...

Formaldehyde emission in galaxies

open access: yesThe Astrophysical Journal, 1993
Nine detections of extragalactic emission in the 4.83 GHz 1 10 -1 11 formaldehyde transition are presented in addition to the only previously known extragalactic emission source in IC 4553. Formaldehyde emission occurs among both OH absorbers and emitters. In contrast with the high-detection rate of extragalactic sources in this survey, there are only

Reducing formaldehyde emission of urea formaldehyde-bonded particleboard by addition of amines as formaldehyde scavenger [PDF]

open access: yesBuilding and Environment, 2018
Abstract Particleboard is one of the building materials that contribute to the emittance of formaldehyde in enclosed area. In order to reduce the formaldehyde emission from particleboard, amines were added into the urea formaldehyde (UF) resin as formaldehyde scavenger. The amines used were methylamine, ethylamine and propylamine.

Formaldehyde sensor using non-dispersive UV spectroscopy at 340nm [PDF]

open access: yes, 2014
Formaldehyde is a volatile organic compound that exists as a gas at room temperature. It is hazardous to human health causing irritation of the eyes, nose and throat, headaches, limited pulmonary function and is a potential human carcinogen.

The influence of decorative surface of commercial particleboards on the formaldehyde release measured by flask method [PDF]

open access: yesGlasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2018
The formaldehyde release and the formaldehyde content from the commercial particleboards were determined using the flask and perforator methods. Since the melamine faced boards were used in this research, the flask method was applied to evaluate

Natural Additive for Reducing Formaldehyde Emissions in Urea-Formaldehyde Resins

open access: yesJournal of Renewable Materials, 2016
This work studies the use of soy protein as a natural formaldehyde scavenger in wood particleboard production. The protein is incorporated in two forms: a) as a powder, during the blending process of wood particles with urea-formaldehyde binder resin, and b) as an aqueous solution, added at different times during resin synthesis.

Satellite observations of formaldehyde over North America from GOME [PDF]

open access: yes, 2000
Formaldehyde (HCHO) is an important indicator of tropospheric hydrocarbon emissions and photochemical activity. We present HCHO observations over North America for July 1996 from the GOME instrument on-board the ESA ERS-2 satellite.
