微细氰化尾矿颗粒絮凝沉降实验研究

, 2015
微细氰化尾矿颗粒沉降速度慢，脱水困难，需借助絮凝剂改善其沉降特性。文中主要将阳离子絮凝剂HLM 和非离子絮凝剂 PAM 对3种平均粒径分别为30，14，3μm 的氰化尾矿悬浮液进行了絮凝沉降及除浊实验，确定其最佳投加量，并对比了2种絮凝剂对不同粒度尾矿的絮凝性能。结果显示，对于3种不同粒度分布的悬浮液，HLM 的絮凝效果均优于 PAM，并且尾矿颗粒的粒径越小 ...

基于KH570-PS表面修饰纳米Al₂O₃环氧树脂复合材料的性能分析

Dianci bileiqi
为改善电力系统中环氧树脂复合材料在湿热环境中的综合性能，本研究使用硅烷偶联剂（KH570）对纳米Al2O3进行接枝改性，并用苯乙烯（PS）接枝处理增强了纳米Al2O3在环氧树脂中的相容性，分别制作纳米Al2O3含量分别为1%、3%和5%的改性环氧树脂样品，从测试样品的微观形貌，表面凝露质量，静态接触角、吸水率、表面/体积电阻率等方面，探究了不同质量分数的改性纳米Al2O3对环氧树脂性能的影响。结果表明：经KH570-PS接枝改性后的纳米Al2O3粒子，可以均匀分散于环氧树脂中，环氧树脂表面无明显团聚现象；

弃采高变质煤下火烧蚀变岩内摩擦角对露天矿边坡稳定的影响研究

, 2013
火烧区煤层开采通常采取火烧高变质煤不进行剥采工作,只剥采原煤的方式开采,因此,弃采高变质煤下火烧蚀变岩内摩擦角对露天矿边坡稳定的影响研究具有必要性。以别斯库都克露天煤矿KT2剖面为例,在弃采高变质煤方案下,研究火烧蚀变岩内摩擦角对露天矿边坡稳定性的影响,得到不同火烧蚀变岩内摩擦角条件下露天矿边坡的稳定系数,进而对边坡稳定性进行评价 ...
