摘要

本研究是建立在我国资源和工业技术基础之上，探讨利用木纤维以半干法制造石膏纤维板（ＧＦＢ）的生产工艺；提出了半干法石膏纤维板的工艺方案，并建立了密度、木膏比、水膏比与板材性能的数学模型。结果表明：密度（Ｄ）增加，板材力学性能显著提高，木膏比（Ｗ／Ｇ）、水膏比（Ｈ／Ｇ）有较强的交互影响。木膏比增大，板材反弹率和吸水厚度膨胀率（ＴＳ）增加，纤维形态、蒸煮工艺对板材静曲性能无显著影响，纤维形态对内结合强度（ＩＢ）和吸水厚度膨胀率影响显著。

Abstract

In this study gypsum fiber board(GFB)was reinforced with wood fiber prepared by defibrator.The paper described the relationship between mechanical properties and wood/gypsum( W/G )ratio,water/gypsum( H/G )ratio and density was also established a mathematics models concerned.The results showed that MOR/MOE/IB increased significantly along with density increase; W/G ratio and H/G ratio were cross impacted,which had strong influence on board properties;both spring back and TS increased along with W/G increase;fiber pattern had significant effect on both IB and TS ;and defibering condition had little effect on MOR/MOE .
