研究了颗粒预处理对木塑复合材料(WPC)生物降解的影响。用未经处理和预处理的枣树叶中脉颗粒制成的WPC。在添加偶联剂之前，木屑经过预处理或用冷水或热水提取，与聚丙烯混合制成板材，然后表面接种子囊菌真菌哈茨木霉T6776。用扫描电子显微镜(SEM)和电子色散X射线能谱(EDX)对WPC表面进行了研究。与对照相比，哈茨木霉菌丝在未经处理的枣树掌中脉颗粒制成的WPC表面生长密集，菌落清晰可见。与对照和未处理的颗粒相比，枣树颗粒的预处理抑制了哈茨木霉的生长。结果表明，颗粒预处理可能是一种合适的方法来限制红枣棕榈中脉木塑复合板表面霉菌的生长。
The effect of particle pretreatments on the biodeterioration of wood-plastic composites (WPCs) was investigated. WPCs made from untreated and pretreated frond midrib particles of date palm were used. Before the addition of a coupling agent, the wood particles were pretreated or extracted with either cold or hot water and mixed with polypropylene to produce panels, which were then superficially inoculated with an ascomycete’s fungus Trichoderma harzianum T6776. The WPC surfaces were studied using scanning electron microscopy (SEM) and electron dispersive X-ray spectroscopy (EDX) measurements. In comparison with the control, an intensive growth of T. harzianum hyphae was found over the WPC surface manufactured from untreated date palm midrib particles with the colonies clearly visible. The pretreatments of date palm particles reduced the growth of T. harzianum in comparison with the control and untreated particles. The results suggested that particle pretreatments could be a suitable way to limit the growth of molds over WPC surfaces made from date palm midrib.
