所有工业部门在生产过程中都使用大量的无机盐产品。我国无机盐总产量仅次于美国和苏联,在国内化工产品产量中居第三位。无机盐中有部份是高能耗的产品。所谓“四槽两炉”是“电老虎”。在广东的无机盐生产中,氯酸钠电解槽、双氧水电解槽、氯碱电解槽、高锰酸钾电解槽等“四槽”的电耗约占广州市化工生产电耗的24%;而电石炉和黄磷炉“两炉”的电耗约占化工电耗的28%。所以在无机盐的生产中节省电耗是一个极需重视的问题。 相似文献

The outstanding mechanical properties of soft materials i.e. natural rubber are partly due to the organic–inorganic nanomatrix structure because numerous organic microparticles are dispersed in a small amount of an inorganic nanomatrix composed of inorganic nanoparticles and organic macromolecules. Here we form an organic–inorganic nanomatrix using graft-copolymerization of a vinyl monomer with an inorganic oxide precursor onto natural rubber particles with an average diameter of 1 μm dispersed in water. The inorganic oxide precursor is converted into inorganic oxide nanoparticles through hydrolysis and condensation, forming chemical linkages between natural rubber microparticles and inorganic oxide nanoparticles. Transmission electron microscopy indicates that the organic–inorganic nanomatrix is densely filled with inorganic oxide nanoparticles and the natural rubber microparticles are dispersed in the nanomatrix. This nanomatrix composite realizes both energetic elasticity and entropic elasticity of a soft material, opening a novel field of building block chemistry with respect to a pair of organic microparticles and inorganic nanoparticles. 相似文献

One of the major limitations of the application of membrane processes in water and wastewater treatment is inorganic fouling. Despite the extensive studies on concentration polarization and inorganic scaling in membrane filtration, the fundamental mechanisms and processes involved in inorganic fouling are not fully understood. This paper critically reviews the mechanisms and models of concentration polarization and inorganic fouling in pressure-driven membrane processes. Effects of operating parameters and membrane properties on the formation of inorganic scale at the membrane surface are also evaluated. Future research areas that need to be pursued to alleviate inorganic fouling problems in membrane installations are discussed. 相似文献
