Effect of Veneer-Drying Temperature on Selected Properties and Formaldehyde Emission of Birch Plywood. [PDF]

open access: yesPolymers (Basel), 2020
In this study, the effect of the veneer-drying process at elevated temperatures on selected properties and formaldehyde emission of plywood panels was determined. We assume that during the veneer drying at high temperatures, more formaldehyde is released

On amine treated polyoxymethylene (POM) blends with low formaldehyde emission for metal injection moulding (MIM)

open access: yesJournal of Materials Science, 2022
When polyoxymethylene (POM)—a common polymer used in metal injection moulding feedstock—is exposed to heat and oxygen during compounding, it can be easily decomposed, releasing undesired gaseous formaldehyde products.

Simultaneous Improvement of Formaldehyde Emission and Adhesion of Medium-Density Fiberboard Bonded with Low-Molar Ratio Urea-Formaldehyde Resins Modified with Nanoclay

open access: yesJournal of the Korean Wood Science and Technology, 2021
1) In wood-based composite panels, low-molar ratio (LMR) urea-formaldehyde (UF) resins usually result in reduced formaldehyde emission (FE) at the expense of poor adhesion.

Low-formaldehyde emission composite particleboard manufactured from waste chestnut bur

open access: yes, 2021
Chestnut bur is an agro-waste material generated in the chestnut production. It is a tannin-rich lignocellulosic material which might be a promising raw material for low-formaldehyde composite particleboard production when using urea–formaldehyde (UF) as

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

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

Impact of formaldehyde and VOCs from waste treatment plants upon the ambient air nearby an urban area (Spain) [PDF]

open access: yes, 2016
Emission factors of formaldehyde and VOCs were determined for two waste treatment plants (WTP) located in the metropolitan area of Barcelona city. Formaldehyde emission factors were determined from the biogas engines exhausts and the process chimneys ...
