俄罗斯研究者用农林业废料与聚乙烯等化学材料混合,制成了可在土壤中自然降解的聚合物基生物复合包装材料。列汉诺夫经济大学研究人员在新一期荷兰《聚合物和环境杂志》上报告说,他们将葵花子的外壳、小麦谷糠、木材的锯末制成木质纤维粉颗粒,另用亚麻和小麦茎秆的纤维制成颗粒,并把上述两类颗粒中的每一种分别与聚乙烯等化学聚合物按一定比例混合,其间还加入含EVA(乙烯-醋酸乙烯共聚物)树脂的 Russian researchers used agrochemical waste to mix with chemical materials such as polyethylene to make polymer-based bio-composite packaging materials that naturally degrade in the soil. Researchers at Leuchnoff University of Economics report in a new issue of the Netherlands Journal of Polymer and Environmental Science that they make the lignocellulosic particles from the sunflower seed hulls, wheat bran, sawdust from wood, and flax and wheat stems Stalk fibers are made into granules, and each of the above two types of granules is separately mixed with a chemical polymer such as polyethylene in a certain ratio, and a mixture of EVA (ethylene-vinyl acetate copolymer) resin
