Effect of Pressing Process of Impregnated Paper on Surface Bonding Strength of Ultra-Thin Fiberboard
摘要
Abstract
The ultra-thin fiberboard,a novel wood material made with high precision,advanced processing,and high added value,has emerged in recent years.This material features a thin thickness,high density,and a smooth surface,making it widely applicable in the decorative materials industry.To investigate the critical parameters and the underlying mechanism of surface bonding performance for melamine-impregnated film paper-coated ultra-thin fiberboard,an L16(45)orthogonal test was conducted to examine the effects of hot-pressing temperature,time,and pressure.Additionally,single-factor tests were employed to analyze the impact of the sanding process and the initial moisture content of the ultra-thin fiberboard on the surface bonding strength of the melamine-impregnated film paper-coated ultra-thin fiberboard.The results indicated that the surface bonding strength was primarily affected by the hot-pressing temperature.Under the optimal conditions(hot pressing time:10 seconds,temperature:205°C,pressure:2.7 MPa),the surface bonding strength reached its maximum value of 1.95 MPa.The surface bonding strength of ultra-thin fiberboard with 180-mesh sanding was 1.5 times higher than that without sanding.When the initial moisture content of the ultra-thin fiberboard was approximately 8%,the surface bonding strength was optimal.Furthermore,SEM and contact angle analysis revealed that sanding treatment increased surface roughness,while an initial moisture content of approximately 8%enhanced hydrophilicity,facilitating stronger mechanical interlocking and interfacial wetting between the ultra-thin fiberboard and the melamine-impregnated film paper.关键词
