简介:Anionomer类型水运的聚氨酯分散(手)被获得从poly(丙烯乙二醇)(PPG),isophoronediisocyanate(IPDI)和通过修改prepolymerisocyanate的dimethylolpropionic酸(DMPA)处理。聚氨酯的二个系列被准备(组A和B)并且一个新预言模型基于灰关系分析被介绍在几个性质上预言原料的影响顺序例如固体内容,粘性,酸数字和聚氨酯的电解稳定性。模型罐头成功地通过设计示范实验在性质上预言原料的影响,这被发现。而且,预言模型的结果证明DMPA在粘性,部分酸价值和电解稳定性起一个关键作用。
简介:纸是调查利用建设和拆毁(C&D)的可能性的礼品的目的作为波特兰水泥的代用品浪费未加工的饭。那么被使用的C&D浪费,再循环的具体总数(RCA)和再循环的石工技术总数(RMA)在古代希腊的一地方区域从拆毁的大楼被导出,希腊。因为他们的石灰质、硅质的起源,RCA和RMA样品分别地被选择,它遵守了平常的波特兰水泥的作文未加工的饭。为那个原因,水泥的六件样品未加工的饭被准备:有平常的原料的作为一件参考书样品,并且五由在适当比例与RCA和RMA混合参考书样品。产生混合物的反应上的效果,在1350°C,1400°C和1450°C在混合物sintered根据免费石灰内容(fCaO)被评估。测试证明增加的再循环的总数改进了水泥的灼伤能力没有否定地影响水泥clinker性质的未加工的饭。而且,生产的钱ers(在1450°C的sintered)的主要部件(C3S,C2S,C3A和C4AF)的形成被X光检查衍射(XRD)支持。
