【摘要】 本文利用QUV耐候加速仪UVA-340模拟稻草暴露在室外环境中的降解效果对苄基化改性稻草的光降解性能进行了检测,并与天然稻草的降解进行比较,同时对光降解的天然稻草与苄基化改性稻草进行红外光谱检测。研究结果表明天然稻草与苄基化改性稻草的失重率比较接近,稻草粉中部分羟基已被取代发生了改性,改性后的稻草木质素含量有了明显的降低。更多还原

【Abstract】 Photodegradation performance of benzylated straw is examined by QUV accelerated weathering tester UVA-340 and nature straw is examined at the same time for the purpose of comparison. Infrared spectrum technique is employed to measuring nature straw and benzylated straw, which have been photo degraded. The results show that the date of weight loss of benzylated straw and that of nature straw are similar. A part of hydroxyl has been replaced and etherified and content of lignin in modified straw has reduced.更多还原
