摘要
介绍了聚乙烯醇改性的方法及原理,重点阐述了改性对聚乙烯醇性能的影响。同时介绍了聚乙烯醇在农用、包装、生物医学等领域的改性发展方向及应用前景。分析了聚乙烯醇改性存在的问题,针对传统塑料难降解的缺陷,提出了改性要向生物降解性能靠拢。针对PVA产品原料价格比PE产品高的问题,提出了改性要高质、低价。
The method and principle of PVA modification were introduced,and the impact of modification on the performance of PVA was emphasized.The development direction and application prospects of PVA in agricultural,packaging,biomedical and other fields were also introduced.The existing problems of PVA modification were analyzed.In the view of the defect that traditional plastics were difficult to degrade,the modification was proposed to be close to the biodegradability.Aiming at the problem of higher raw material prices of PVA products than PE products,it was proposed that the modification should be studied at high quality and low price.
