通过煅烧高钙镁磷矿分解碳酸钙镁盐可有效提高磷矿品位。对煅烧后的磷矿进行水化、浸取得到低镁磷精矿和硝酸钙镁浸取液,对浸取液进一步沉淀以回收制备氢氧化镁。然而,在氢氧化镁生产过程中存在固液分离困难和产品纯度低的问题,系统研究了不同温度下湿滤饼的性质、比阻、沉降性能等。结果表明:较低温度下滤饼吸附水分大、过滤困难、洗涤负担大;当温度升高到70℃时,可有效破坏氢氧化镁胶体,从而减少滤饼对水分的吸附,减轻洗涤负担,显著改善氢氧化镁的沉降性能和过滤性能,沉降速率高达0.051 8 mL/min,过滤比阻低达(5.82±1.1)×10^(11) m/kg,镁的回收率可达72%。进一步对沉淀过程进行模拟分析,提出以分步沉淀方式实现杂质的预分离,从而提高氢氧化镁纯度,使其达到工业级氢氧化镁Ⅲ类合格品的要求。

The switchable oil layer driven by electrowetting gives visible color and light valve control, which is the basis of Electro-Fluidic Displays. The colored oil’s property is a key factor that influences the Electro-Fluidic Displays switching behavior. A purple oil was formulated by the oil-soluble purple dye in decane in this study. The dye molecule itself is nonpolar and it doesn’t dissolve in water. The concentration of colored oil influenced the oil/water interfacial tension and oil viscosity. The relationship of EFD switching behavior with oil/water interfacial tension, oil viscosity, and oil conductivity has been systematically investigated. The oil/water interfacial tension decreased with increasing oil concentration, in the meanwhile, the conductivity increased. Oil conductivity was one of the key factors that influenced the Electro-Fluidic Displays optical property. We found for the first time that at the lower oil concentration (2% - 10%), the interfacial tension plays a main role effect on the rupture voltage and response time, but as the conductivity of higher concentration of colored oil increased (at 20%), the rupture voltage-controlled both by conductivity and interfacial tension.

目的筛选降脂理肝汤主要活性成分,预测其活性成分的作用靶点,探讨降脂理肝汤治疗非酒精性脂肪肝病(non-alcoholic fatty liver disease,NAFLD)的多成分-多靶点-多通路作用机制。方法通过多个数据库联合检索并筛选降脂理肝汤活性成分和其作用靶点以及NAFLD相关靶点,并预测降脂理肝汤治疗NAFLD的潜在靶点。采用Cytoscape软件构建降脂理肝汤活性成分-作用靶点网络,通过Cytoscape的插件Clue GO对靶点基因功能及通路进行富集分析。结果网络分析结果表明,从降脂理肝汤中筛选得到82个活性成分,涉及NAFLD靶点53个,靶点主要关联NAFLD中胰岛素抵抗、氧化应激和炎症反应,并且参与了NAFLD中PI3K/Akt信号通路、炎症小体途径、白细胞介素-10(IL-10)信号通路以及T细胞信号通路,这些生物过程和信号通路介导了降脂理肝汤干预NAFLD潜在机制。结论为进一步深入研究降脂理肝汤治疗NAFLD作用机制提供了重要依据。
