The effect of acidic ionic liquid (IL) as a new catalyst on the properties of wood-based panels bonded with urea-glyoxal (UG) resins was investigated. Different levels of N-methyl-2-pyrrolidone hydrogen sulfate ([HNMP] HSO4 (0, 1, 2, 3 wt %)) were added to prepared UG resin. The resin was then used for preparing laboratory particleboard panels. Then, the properties of the prepared panels were e...

The recent development of inexpensive, compact hyperspectral transmissometers broadens the research capabilities of oceanographic applications. These developments have been achieved by incorporating technologies such as micro-spectrometers as detectors as well as light emitting diodes (LEDs) as light sources. In this study, we evaluate the performance of the new commercial LED-based hyperspectr...

Abstract To make a UV-thermal curing solution based on bisphenol A, epoxy acrylate (EA) and resin of diglycidyl ether A (DGEBA) were uniformly mixed. The Blends module in the Materials Studio software was used to carry out molecular dynamics simulation blending compatibility evaluate rationality achieve through interaction parameters, binding energy, phase diagram. energy distribution DGEBA EA ...

Lefebvre, Kevin, "Miscibility and influence on each other of a UV photo-initiated thermosetting polymer blend of radical and cationic systems" (2013). Thermoset blends engage an interest into polymer materials using photopolymerization. Our work is inscribed within a project which consists to control the degree of crosslinking in three dimensions during UV photo-curing. Two different reaction m...

Accurate temperature control is required in advanced heat treatment processes such as composite curing. The crux how to determine the appropriate sources which would result distribution during part heating process. This paper presents a new thermal method using digital image based programming, efficiently and accurately estimates controls step-wise numerical manner. was validated both simulatio...
