Investigation of some technological properties of composite panels manufactured with urea formaldehyde and melamine ürea formaldehyde resins

In this study different curing chemicals (aluminum sulfate, ammonium chloride) and technological qualities of composite material that is 30 mm thickness produced at the factory were examined by using MUF and UF glues produced test plates are manufactured at the factory by using endless press. In test plates, physical qualities; amount of moisture, increment of thickness, amount of taking water and mechanical qualities; bending strength, modulus of elasticity and pulling testing to surface vertically were done according to standards. The results were analyzed according to different types of glue and different hardener.As a result, all plates produced at average 633 kg/m³ density are approved for standards to areas including furniture that is stated at TS EN 312. Although there isn't important different using different type of hardener statistically, it's seen that technologic qualities of produced plates would be better by using MUF glue for humity places, using ammonium sulfate or ammonium chloride as hardener.
