Comparative Study Of Phenol Formaldehyde And Urea Formaldehyde Particleboards From Wood Waste For Sustainable Environment
TLDR
In this article, the properties of particleboards produced from sawdust with phenol formaldehyde and urea formaldehyde resins were compared and the results showed that the particleboard produced with PFO had better properties compared to that of urea Formaldehyde.Abstract:
This research work was aimed at comparing the properties of particleboards produced from sawdust with phenol formaldehyde and urea formaldehyde resins. The particleboards were produced using varied quantities of particle size 2mm. 30ml each of the resins which was prepared under same conditions, compression temperature of 180 0 C, pressure of 10tons, and pressing time of 15 minutes. The properties of the particleboards were tested and compared. The results showed that the particleboards produced with phenol formaldehyde had better properties compared to that of urea formaldehyde. And the property of the particleboards is a function of the percentage composition of the binder (resin) and the filler (sawdust).read more

TL;DR: In this paper, the results showed that the properties of the particleboards are a function of the percentage composition of the binder (resin) and the filler (sawdust), and that the hardness increased from 88.6 shoreA to 99 shoreA while the percentage of water absorption decreased as the UFR content increased.

Durability and strength properties of particle boards from polystyrene–wood wastes
TL;DR: In this article, the effects of long-term immersion in water for 7-28 days on the properties of the particleboards were similarly evaluated, and the results showed that water absorption decreased as EPS content was increased from 1.5 to 2.0 and thickness swelling indicated that WPP with 0.85 and 1.75mm particle sizes with 2.5 resin dosages had the least value between 2.38 and 3.51%.

Urea Formaldehyde Composites Reinforced with Sago Fibres Analysis by FTIR, TGA, and DSC
TL;DR: In this article, Fourier Transform Infrared (FTIR) spectra are used to characterize the Sago/Urea Formaldehyde composite in terms of their functional group and bonding, and thermal stability results indicate that particle size, particle/matrix interface adhesion, and particle loading have great influence on the thermal properties of the composites.

Chemical modification of wood
TL;DR: In this paper, the main emphasis has to do with the shift from the traditional ways of treating woods in order to improve their resistance to atmospheric and biological degradation, to chemical modifications which eliminate the problem of leaching of toxic materials into the environment.
