摘要
玉米黄粉与豆渣混合后,由双螺杆挤压机挤压制成母粒,然后母粒再被挤压成型为试验片,进行可降解塑料的研究。对试验片的强度特性、热稳定性及内部结构进行了研究和观察。研究发现,添加质量分数为20%豆渣的试验片拉伸强度最大。通过扫描电镜观察发现,试验片有一个均一的相。热质量分析的结果表明,豆渣质量分数为20%的试验片,在240℃以下时能保持热稳定性。
Corn gluten meal （CGM） first blended with bean dregs, the mixtures were extruded into pellets using a twin-screw extruder, and the pellets were extruded again as specimens. Tensile strength, thermal stability and morphology of the specimens were investigated. When 20%（w/w%） of the bean dregs were blended, the specimen had a maximum tensile strength. In addition, the specimen had a uniform phase based on observations using scanning electron microscopy （SEM）. The result of thermal gravimetric analysis （TGA） showed that the specimen （containing 20% bean dregs） can keep thermal stability below 240C. The specimen can be applied in agriculture due to its low cost and biodegradability.
