Investigation of some Technological Properties of Composite Panels Manufactured with Melamine Urea Formaldehyde
Öz
In this study, the technological properties of particleboard using melamine urea formaldehyde (MÜF) and urea formaldehyde (UF) adhesives and different hardener chemistries (aluminum sulphate, ammonium sulphate and ammonium chloride) were investigated. Continuous press is used for the production of panels. Physical properties; Moisture content, thickness increase and water uptake and mechanical properties; bending strength, modulus of elasticity and tensile strength were investigated according to the relevant standards. The results were compared according to different resin and hardener types.
As a result, all boards were found to meet the standards (TS-EN 312) produced at a density of 30 mm thickness and a target average of 633 kg / m³. It has been shown that using different hardeners in production board does not make a significant difference. However, it is suitable to use MÜF resin for damp environments. As the hardener, ammonium sulfate or ammonium chloride may be preferred.
