Use of Silicon Based Chemicals in Medium Density Fibreboard Production
Öz
Aim of study: The purpose of this study was to determine the effect of the type and concentration ratios of chemicals on the mechanical and physical properties of medium density fiberboards (MDF) produced with some silicon-based water-repellent chemicals.
Material and method: In this study; Dow Corning 87 (DC) - Xiameter PMX-200 1000cs (XM) chemicals, which have water-repellent properties, were mixed with melamine urea formaldehyde adhesive in three different concentrations and used in the production of medium density fiberboards (MDF). The water absorption, thickness swelling, bending strength, elasticity modulus, and tensile strength properties of the produced boards were determined.
Main results: It was determined that the water absorption and thickness swelling properties of the boards produced with DC and XM chemicals improved according to the control board. The lowest water absorption values were obtained in boards with 3% DC and 1.5% XM, and the lowest values in thickness swelling values were obtained in boards with 1.5%-3% DC and 1.5%-3% XM. The findings revealed that the tensile and bending strength values of boards produced using the XM and DC chemicals exhibited an increase compared to the control board.
Research highlights: It has been determined that DC and XM chemicals improve the physical and mechanical properties of MDF boards
