Zusammenhänge zwischen Eigenschaften,Rohstoffkomponenten und dem Dichteprofil von Spanplatten

Modulus of elasticity (MOE) and bending strength (MOR) are particleboard properties which characterize their suitability for definite specifications. During pressing and curing of the binding agent a density distribution over the cross-section of the boards, typical of prevailing production conditions, is achieved. These density profiles have a decisive influence on board properties. Based on test results various mathematical profile evaluation methods and regression analyses are described, with which to improve the knowledge of how to influence board properties. This provides an extension, at reduced cost and material consumption, of ways and means to adapt several distinctive properties to certain specifications.
