摘要
研究了聚甘油硬脂酸(PGFE)酯作为流滴剂使用时其羟值、酯值、酸值对农用膜无滴性的影响,并且对聚甘油的聚合度与无滴性之间的关系进行了探讨。结果表明:PGFE的羟值为350、酯值为148、酸值小于3时农用膜无滴性好。
Effects of the hydroxyl value, ester value and acid value of polyglycerol fatty acid ester on antifogging property of agricultural films were studied. The relation between the antifogging property and the polyglycerol polymerization degree was discussed. The results show that when the hydroxyl value,ester value of polyglycerol fatty acid ester are 350, 148, and the acid value is below 3, antifogging property of agricultural films is good.
