| 摘 要： | 本试验选用聚苯乙烯泡沫塑料和GR6作为隔热材料进行粮面压盖隔热保冷试验。从试验结果来看：聚苯乙烯泡沫塑料和GR6均有一定隔热保冷作用，GR6的隔热性能略优于聚苯乙烯泡沫塑料。试验表明墙体传热也是促使整仓粮温上升的一个重要原因。另外，本试验还初步分析了谷物冷却后粮堆各个部位粮食温度的变化规律。

| Abstract: | Polystyrene foamed plastics and GR6 used to cover the surface of grain bulk for insulation heat were tested.The results showed that both polystyrene foamed plastics and GR6 have the function of insulation heat,GR6 was a little superior than polystyrene foamed plastics.It also showed that heat delivering from wall was an important reason for rising of grain temperature in warehouse.The change law of grain temperature in different parts of the grain bulk after cooled was analysed preliminaryly. |
