Sewage contains a variety of components including oil slick and water-soluble pollutants. How to remove different types of pollutants at the same time is a challenge. In this paper, superhydrophobic fabric (SH fabric) was prepared by the combination of silver phosphate photocatalyst with fabric substrate. Surface oil slick and rhodamine B contaminants can be removed simultaneously by SH fabric. The degradation efficiency after three cycles is still maintained above 90% under outdoor light source conditions. In order to improve the degradation efficiency of silver phosphate photocatalyst, ethanol/water mixed solvent was used. And the reasons for the improvement of catalyst performance were studied systematically. It is found that the charge transfer resistance of the silver phosphate catalyst prepared by addition of ethanol (S-3) decreases, while the carrier concentration and lifetime increase. The VB and CB of silver phosphate with the best degradation performance (S-3) are 2.425 eV and 0.135 eV, respectively. It is hoped that this SH fabric could provide a new solution to the improvement of catalyst performance and comprehensive treatment of sewage. 相似文献

MoS2 nanoparticles have been considered valuable materials in lubricating applications due to their layered morphology. This work synthesized spherical MoS2 nanoparticles that held many nanosheets through the hydrothermal method. The thickness of these sheets is between 10 and 25 nm, and their length is estimated to be about 200 nm. The effect of nanoparticles concentration on wear properties was investigated in this research. The four-ball test measured the wear performance of nano lubricants. The results showed that all nano lubricants had better wear performance than the base lubricant (Behran Compressor 68). However, molybdenum disulfide nanoparticles synthesized as nanosheets with a thickness of 10 nm had the best performance. At a concentration of only 0.05 wt-%, the resulting nano lubricant reduced the wear width and friction coefficient by about 50%. The thermal conductivity coefficient results also showed that nanoparticles increased this coefficient. As the lubricant temperature increases, the difference between the nano and base lubricant's thermal conductivity increases. 相似文献

探讨聚醚硅油作为浆纱助剂的应用效果。测试了加入不同量聚醚硅油的磷酸酯淀粉和PVA混合浆浆膜的性能,并对T/C 80/20 13 tex混纺纱线、C 13 tex纱线进行了上浆试验,对比了不同配方下浆出纱线的回潮率、退浆率、耐磨性、强力、毛羽和减伸率。试验结果表明:在原浆料配方基础上加入3%的聚醚硅油用于T/C 80/20 13 tex纱上浆和在原浆料配方基础上加入4%的聚醚硅油用于C 13 tex纱上浆,浆纱性能可得到较大程度改善。指出:在原有配方中加入适量的聚醚硅油可有效改善浆纱性能;聚醚硅油加入量应根据不同纱线上浆要求进行调整。 相似文献

The upgrading potential of quince (Cydonia oblonga Miller) wastes was evaluated for production of fiber-rich powders with useful functional and physiological properties. As a first approach, three products were obtained by applying different drying conditions without or with a previous extraction either with water or ethanol. Chemical compositions as well as physical and functional properties of the isolated fractions were evaluated in relation to water or oil absorption for characterization. The products obtained presented interesting hydration properties comparable to those reported for citrus and apple pulps. At the same time, all dried fractions showed high spontaneous water absorption rate in the kinetics assay. Oil absorption seemed to essentially depend on the microstructural characteristics of the fiber powders, whereas parameters involving water absorption were really determined by the material’s hydrophilicity. Specific volume, which was also in part a direct function of structural differences, was associated to the ability for oil uptake. 相似文献

目前,在我国具有一定规模的禽用油脂精炼工厂(车间)中,以物理精炼或化学精炼的方法加工着不同品种的植物油脂,或以此两种不同的方法加工着同一品种的油脂。这两种方法的优缺点已成为多年来争议的焦点之一。列举了物理精炼和化学精炼中的许多因素,并加以对照、比较,以期对它们有更好的了解。 相似文献

Fourier transform (FT) Near Infrared Spectroscopy (NIR) spectrometry in combination with partial least squares (PLS) regression
was used for direct, reagent-free determination fat and moisture content in milled olive and olive pomace. The two calibration
models obtained were built with samples from two years harvest (2006/2007) and have a good predictive power considering the
nature of the samples and are both being used in an industrial plant. 相似文献

Physico-chemical properties of fried rice crackers were studied as a function of fish powder content, processing conditions, frying temperature and frying time. The results showed that addition of fish powder content at 5, 10 and 15 g/100 g reduced the oil uptake by approximately 10, 14 and 22 g/100 g (db), respectively in comparison to the control without fish powder. The deep fried rice crackers mixed with fish powder tended to be lower in hardness, lower in expansion ratio and higher in bulk density in comparison to the control sample. The color parameter, L∗ of fried rice crackers decreased with increase in fish powder content. In contrast, a∗ and b∗ values increased with increase in fish powder content. The moisture content of deep fried rice crackers decreased with increase in frying temperature and frying time. The oil uptake in fried rice crackers increased with increase in frying time but decreased with increase in frying temperature. With increase in frying temperature and time, the texture of rice crackers became harder, the bulk density increased, and the expansion ratio decreased. The optimum conditions resulting in desirable physico-chemical properties and minimum oil uptake were rice crackers with fish powder content of 9 g/100 g, fried at a temperature of 220 °C for 60 s. 相似文献
