PRODUCTION OF HIGH DENSITY PARTICLEBOARD USING MELAMINE-UREA-FORMALDEHYDE RESIN

open access: yes, 2015
This research was developed aiming to evaluate the effects of board density and melamine-urea-formaldehyde resin on the properties of particleboard for semi-structural applications. The boards were manufactured with nominal density of 0.65 g/cm³ and 0.90 g/cm³ using urea-formaldehyde resin as control and melamine-urea-formaldehyde. The results showed a

Demonstration of co-polymerization in melamine–urea–formaldehyde reactions using 15N NMR correlation spectroscopy

open access: yesPolymer, 2005
Abstract Melamine–urea–formaldehyde resins are very important commercially, yet little is known about their structures, and the techniques that have been available to examine this are quite limited. In this manuscript we describe the use of 1H–15N HMQC NMR spectroscopy and the development of a doubly-selective 1H–15N–13C CP INEPT NMR experiment, to ...

Effects of Steaming, Drying Temperature, and Adhesive Type on Static Bending Properties of LVL made of Picea orientalis and Abies nordmanniana veneers

open access: yesBioResources, 2014
The modulus of elasticity (MOE) and modulus of rupture (MOR) were evaluated for laminated veneer lumber (LVL) in static bending. The studied species were spruce (Picea orientalis) and fir (Abies nordmanniana) originated from the Eastern Black sea region ...

Synthesis and Characterization of Melamine‐Urea‐Formaldehyde Microcapsules Containing ENB‐Based Self‐Healing Agents

open access: yesMacromolecular Materials and Engineering, 2009
AbstractMicrocapsules for self‐healing applications were produced with a melamine‐urea‐formaldehyde (MUF) polymer shell containing two different healing agent candidates, 5‐ethylidene‐2‐norbornene (ENB) and ENB with 10 wt.‐% of a norbornene‐based crosslinking agent (CL), by in situ polymerization in an oil‐in‐water emulsion.

Effect of Sepiolite Filler in Malamine-Urea-Formaldehyde Resin on the Properties of Three-ply Plywood

open access: yesBioResources, 2015
A low-cost sepiolite (SEP) was used to replace wheat flour (WF) as a filler applied to melamine-urea-formaldehyde (MUF) resin. Three-ply plywood was fabricated with different SEP/WF formulations, and its wet shear strength and formaldehyde emission were ...
