Effect of wood acidity and catalyst on UF resin gel time

Holzforschung, 2004
Abstract Knowledge of pH and buffering capacity of raw fiber materials is important for understanding the effects of raw material on the curing rate of urea formaldehyde (UF) resin, used for panel manufacturing, especially with some less-desirable wood materials such as bark, top, and commercial thinnings.

UF resin efficiency of MDF as affected by resin content loss, coverage level and pre-cure

Holz als Roh- und Werkstoff, 2006
A full-factorial experimental design was used to investigate the effects of three factors on UF resin efficiency. Within the limits of this study, the three factors, namely, resin content loss, resin coverage level and resin pre-cure time for mechanical blended MDF fibres were found to have significant effects on resin efficiency as evaluated by the ...

Surface characteristics and physical properties of wheat straw particleboard with UF resin

Journal of the Indian Academy of Wood Science, 2014
Agricultural fibers, such as straw and plant stalks, have been considered as renewable alternatives for making particleboard, which would ease the huge demand for wood. The objective of this study was to investigate surface characteristic (surface roughness and wettability) and physical properties (thickness swelling and water absorption) of wheat ...

Preparation and Characterization of Silicone Oil/UF Resin Microcapsules as Erosion Inhibitor

Key Engineering Materials, 2016
Microcapsules with silicone oil as core and poly (urea-formaldehyde) as shell were prepared by direct in-situ polymerization process. The influences of formaldehyde-urea molar ratios on microcapsules morphologies were investigated by scanning electron microscope (SEM).

Influence of UF resin on pyrolysis characteristics of biomass components: A thermogravimetric study

Proceedings of 2012 International Conference on Biobase Material Science and Engineering, 2012
In order to study the pyrolysis characteristic of biomass components, especially the influence of urea formaldehyde resin (UF) on different components, compositional study on thermogravimetric analysis was carried out on cellulose, xylan, lignin and UF resin. The three main components as well as the ones mixed with UF resin ran the same heating pattern.

Preparation of Water-Resistance Plywood with UF Resin Modified by Emulsifiable Polyisocyanate

Applied Mechanics and Materials, 2010
The purpose of the study was to manufacture water-resistance plywood with using UF resin modified by emulsifiable polyisocyanate. The emulsifiable polyisocyanate which contains plenty of hydrophilic segments and teminal isocyanate groups were synthesized by reaction between various kinds of polyether polyols and polymeric methane dipthenyl diisocyanate
