| 1 | 硫化锌精矿直接浸出动力学及其半经验模型(英文)显示文摘在中试规模管式反应器中直接浸出贫铁硫化锌精矿,研究其浸出动力学。为满足静压浸出条件,将含硫酸亚铁和硫酸的矿浆注入到垂直放置的直径8 m的管式反应器中,空气从反应器的底部吹入。考察了初始硫酸浓度、反应温度、矿粒直径、初始硫酸锌浓度、矿浆浓度和铁含量对反应动力学的影响。结果表明,硫化锌精矿的直接浸出遵循收缩核模型,过程受化学反应控制,其表观活化能为49.7 k J/mol。采用半经验模型描述该过程,得到铁含量、硫酸浓度、硫化锌精矿浓度和矿粒直径的反应级数分别为0.982、0.189、-0.097和-0.992。采用SEM-EDS对硫化锌精矿浸出反应前后的矿粒进行分析,发现当锌的浸出率低于60%时,由于反应器搅拌的问题,颗粒表面硫产物层脱落,会影响浸出溶液与颗粒表面的接触。 | Nima SADEGHI Javad MOGHADDAM Mehdi OJAGHI ILKHCHI | 2017 | Transactions of Nonferrous Metals Society of China2017，27，10： | 4 |
| 2 | Investigation on tribological performance of CuO vegetable-oil based nanofluids for grinding operations显示文摘With ball-bearing and tribofilm lubrication effects,CuO vegetable oil-based nanofluids have exhibited excellent anti-wear and friction reduction properties.In this study,CuO nanofluids were synthesized by a one-step electro discharge process in distilled water containing polysorbate-20 and vegetable oil as a nanoparticle stabilizer and source of fatty-acid molecules in the base fluid,respectively.Pin-on-disk tribotests were conducted to evaluate the lubrication performance of synthesized CuO nanofluids between brass/steel contact pairs under various loadings.Surface grinding experiments under minimum lubrication conditions were also performed to evaluate the effectiveness of the synthesized nanofluids in improving the machining characteristics and surface quality of machined parts.The results of pin-on-disk tests revealed that adding nanofluids containing 0.5%and 1%(mass fraction)CuO nanoparticles to the base fluid reduced the wear rate by 66.7%and 71.2%,respectively,compared with pure lubricant.The lubricating action of 1%(mass fraction)CuO nanofluid reduced the ground surface roughness by up to 30%compared with grinding using lubricant without nano-additives.These effects were attributed to the formation of a lubrication film between the contact pairs,providing the rolling and healing functions of CuO nanoparticles to the sliding surfaces.The micrography of ground surfaces using a scanning electron microscope confirmed the tribological observations. | Mirsadegh Seyedzavvar Hossein Abbasi Mehdi Kiyasatfar Reza Najati Ilkhchi | 2020 | Advances in Manufacturing2020，8，3： | 2 |
