静电定向杨木刨花板的研究

<正> 静电定向法是生产定向刨花板的主要方法之一。此方法既能定向大尺寸规整刨花,也能定向碎小刨花,甚至纤维,且能耗很低。 前几年,我国从国外引进的速生杨树种现已成林,如何合理利用已成为迫切需要解决的问题。 为进一步探索静电定向技术、开发速生树种的运用领域,本研究以Ⅰ-69杨[Populus deltoides c.vlux’(ex.Ⅰ-69/55)]为刨花原料,研制新型的静电定向杨木刨花板,重点讨论静电定向的增强机理,并对几种复合板的结构进行比较分析。

STUDIES OF ELECTRALIGNER FLAKEBOARD MADE FROM THE FAST-GROWING POPLAR

This paper aims to study the manufacturing technique of electraligner flakeboard from the Italian fast-growing poplar through a series of tests. The results show that field intensity (E) and flake geometry shape (S) are the main factors influencing MOE, MOR, IB and linear expansion. Highness of the electrode plates do not influence the indexes of properties of the flakeboard in the range of 45cm. The expermental results are theoretically discussed and various foims of electraligner flakeboards compared in this paper.
