重奖求助扬子-巴斯夫EVA或LDPE的工艺技术规程或操作法？ low density polyethylene (ldpe) is a tough, flexible, translucent polymer with low tensile strength but outstanding good dielectric properties. its first use was as an insulator for high frequency cable (radar). its main use is now for films, for packaging and agriculture. ldpe塑料是有韧性、易变形、半透明、抗张强度低的聚合物，但是，它的绝缘性极好。最初用于高频电缆的绝缘体（如雷达），现主要用于农膜、包装膜和食品包装膜。 ldpe has a specific density in the range from 0.915 to 0.935 and is made from polymer-grade ethylene which is compressed up to 3000 barg in several stages and polymerised at a temperature of approx. 150 - 320 °c to give the typical, flexible polymers. ldpe的密度介于0.915～0.935，由聚合级的乙烯通过多段压缩至3000 barg，在大约150 - 320 °c聚合而成。查看更多
MHEATX动态模拟设置问题？ 我刚刚画完流程图，关于mheatx就出现这个问题 the number of hot products and hot feeds must be the same the number of cold products and cold feeds must be the same 关键是我输入和输出是相同的啊 查看更多
