研究開發(fā)可生物降解塑料是解決環(huán)境污染問題的有效途徑。聚丁二醇丁二酸酯(PBS)是一種生物可降解的脂肪族聚酯，具有良好的熱性能、機械性能和加工性能。研究PBS的生物降解性能對其作為一種環(huán)保材料的推廣應(yīng)用具有重要意義。堆肥法是近年來發(fā)展起來的一種評價塑料生物降解性能的方法。其實質(zhì)是依靠自然界中普遍分布的細(xì)菌、放線菌和微生物，促進(jìn)生物可降解有機物轉(zhuǎn)化為穩(wěn)定腐殖質(zhì)的生化過程。該方法可快速、有效、簡單、直觀地評價塑料的生物降解性，在一定程度上能反映塑料在自然條件下的生物降解性。目前，堆肥已成為美國、日本和歐洲評價塑料生物降解性的主要方法。堆肥的國際標(biāo)準(zhǔn)主要包括ISO 14855、ASTM D 5338、JIS K 6953和DIN V54900，其中ISO 14855在《控制堆肥條件下材料的**終需氧生物分解和崩解能力測定》中常用。采用測量二氧化碳排放量的方法。本文研究了堆肥法對PBS的生物降解，進(jìn)一步篩選出有用的能降解PBS的微生物，對PBS的推廣應(yīng)用以及研究特定微生物作用下的降解機理具有重要意義。山東**生物降解母粒誠信經(jīng)營上面是上海羽迪新材料科技有限公司給大家?guī)淼姆窒?，您有任何的疑問和產(chǎn)品需求歡迎詳詢我司。</p><div
