Impact of moisture content, closing speed, and pressurizing speed on the performance of medium density fiberboard (MDF)

The purpose of this research is to investigate the impact moisture content, closing speed, and pressurizing speed hot press on density, uniformity density distribution, properties Medium Density Fiberboard (MDF) products. Moisture content affects plasticity, heat conductivity, hydrolysis reaction fiber appropriate ensures quality board. Excessive can lead defects such as pollution bubbles surface Closing time affect nature, quality, section structure MDF. board varies with time, product properties, especially strength differs largely. influences distribution properties. Fast results in high Modulus Rupture (MoR) low Internal Bonding (IB), while slow leads MoR IB. Pre-plasticizing layer improve MDF by increasing hardness surface. findings provide guidance for optimizing production process improving Applying a fast during manufacturing has resulted 15.7% increase MoR, which measure material’s ability withstand stress before breaking compared using speed. Additionally, led reduction 17.4% IB, resist internal separation or delamination. Therefore, more effective mechanical
