B2O3—Na2O—CuO玻璃的化学组成对铜离子释放量的影响

通过原子吸收光谱,Ｘ－射线衍射和电子自旋共振谱等研究了玻璃的化学组成对铜离子释放量的影响,结果表明,Ｂ２Ｏ３－Ｎａ２Ｏ－ＣｕＯ系统玻璃组成的不同可能导致铜离子释放量的增加或减少,在某些玻璃组成范围内,其铜离了释放量能够比纯Ｃｕ２Ｏ释放量还要多这说明用Ｂ２Ｏ３－Ｎａ２Ｏ－ＣｕＯ系统玻璃作为防污染涂料是可行的。

Development and application of anti-fouling ceramic coating for high-sodium coal-fired boilers

To address the fouling problem in boilers fired with high-sodium coal (HSC), a composite ceramic coating was developed using the slurry method and applied on 15CrMo steel. After sintering, the composite ceramic coating had a dense structure and was well bonded to the substrate forming a metallurgical damascene structure. The fouling and thermal shock resistance of the ceramic coating to sodium sulfate was found be excellent. After five fouling cycles, the uncoated steel had a surface fouling rate of 21.9%, compared to 0% for the coated steel. The composite ceramic coating also demonstrated an appreciable fouling resistance to sodium sulfate. Similar to the flaky oxide film formed on the uncoated steel surface, only a few fine sodium sulfate particles penetrated the microcracks generated during the sintering of the ceramic coating. However, remarkable anti-fouling results were achieved when the composite ceramic coating was applied in an industrial boiler fired with a Zhundong HSC blend.

Study on the control of pore sizes of membranes using chemical methods: Part III. The performance of carbonates and bicarbonates in the membrane-making process by the chemical reaction

In this paper, polyvinylidene fluoride (PVDF)/polymethyl acrilate (PMMA)/cellulose acetate (CA) blend UF membranes were prepared by chemical reaction introduced phase-inversion method. The results of the experiment show that: (1) The membrane pore size distribution is more uniform due to the presence of carbonates or bicarbonates in the coagulation bath; (2) No more than the stoichiometric ratio amount of carbonates or bicarbonates in the coagulation bath can effectively improve the membrane pore size distribution and make the pore size of membrane more uniform; (3) The membrane prepared by carbonates solution as a working solution in coagulation bath possess superior performance than that by bicarbonates.

Fabrication of magnetically responsive anti-fouling and easy-cleaning nanofiber membrane and its application for efficient oil-water emulsion separation

The magnetically responsive anti-fouling nanofiber membrane(MRANM) was fabricated for efficient oilwater emulsion separation,which could be cleaned using oscillating magnetic field.MRANM was prepared by grafting superparamagnetic Fe₃O₄ nanoparticles onto the surface of electrospun polyacrylonitrile nanofiber membrane(PANM),Compared with PANM,the water contact angle of MRANM decreased from 104° to 0°,indicating that the hydrophilicity of the membrane was significantly improv...
