摘要

超薄纤维板作为一种新型的绿色低碳生物质复合材料,在市场上受到了极大的关注。然而,由于热压工艺的复杂性,定量分析热压参数对超薄纤维板性能的影响并不容易。研究了热压温度和热压时间对纤维板物理力学性能的影响。建立了温度、时间和含水率的数学模型,并建立了含水率对板料物理力学性能影响的神经网络预测模型。根据热湿传递机理,建立了超薄纤维板传热传质模型。采用Fluent软件仿真,确定了匹配热压工艺下板材的含水率。该研究有助于优化热压工艺,提高超薄纤维板的产品质量和生产效率。

The mechanism of moisture transport and mechanical model of ultra-thin fiberboard

The mechanism of moisture transport and mechanical model of ultra-thin fiberboard

As a new type of green and low-carbon biomass composite material, ultra-thin fiberboard has received great attention in the market. However, due to the complexity of the hot pressing process, it is not easy to quantitatively analyze the influence of hot pressing parameters on the properties of ultra-thin fiberboard. This study investigated the relationship between the temperature and time of hot pressing, and the physical and mechanical properties of fiberboard through the mechanism of moisture transfer. A mathematical model for temperature, time, and moisture content was established, as well as a neural network prediction model for the influence of moisture content on the physical and mechanical properties of the board. An ultra-thin fiberboard heat and mass transfer model was built according to the heat and moisture transport mechanism. Fluent software simulation was used to determine the moisture content of the boards under the matching hot pressing process. This study helps to optimize the hot pressing process and improve the product quality and production efficiency of ultra-thin fiberboard.
