锌铝镁镀层钢板产品是在传统热镀纯锌镀层产品的基础上,在镀液中添加适量的Al、Mg以及其他微量合金元素得到的合金镀层产品。因其具有良好的耐腐蚀、耐磨损、切口自愈能力和低摩擦因数等特性,在众多领域具有巨大应用前景。本文从光伏支架中钢材的使用现状出发,对热基锌铝镁材料的发展和应用现状进行综述,分析了热基锌铝镁材料在光伏支架中应用的优势和的可行性,发现热基锌铝镁材料直接采用酸洗后的热轧板为原料,可生产规格更厚的产品,更好地满足光伏行业的需求。 相似文献

2015年7月13日,工信部公布《电镀行业规范条件》征求意见稿,以提高行业的准入门槛,加快电镀行业结构调整,控制重金属的污染,进而促进我国电镀行业持续健康发展.该《条件》实施后,短期内规模效应差、环保不达标、技术工艺水平落后的小型镀锌企业将退出镀锌行业,进而减少锌的需求,锌价面临下行压力;但从长期来看,自动化程度高、技术水平领先、环保达标的大型企业发展空间较大,同时其产品镀锌层的规范化将加大锌的消耗,对锌价具有提升作用. 相似文献

The possibility of using unique properties of lanthanides in the nanotechnology is demonstrated. The origination of linear
and nonlinear optical properties of lanthanide compounds with phthalocyanines, porphyrins, naphthalocyanines, and their analogs
in solutions and condensed state and the prospects of obtaining novel materials on their basis are discussed. Based on the
electronic structure and properties of lanthanides and their compounds, namely, optical and magnetic characteristics, electronic
and ionic conductivity, and fluctuating valence, molecular engines are classified. High-speed storage engines or memory storage
engines; photoconversion molecular engines based on Ln(II) and Ln(III); electrochemical molecular engines involving silicate
and phosphate glasses; molecular engines whose operation is based on insulatorsemiconductor, semiconductor-metal, and metal-superconductor
types of conductivity phase transitions; solid electrolyte molecular engines; and miniaturized molecular engines for medical
analysis are distinguished. It is shown that thermodynamically stable nanoparticles of Ln

composition can be formed by d elements of the second halves of the series, i.e., those arranged after M = Mn, Tc, and Re.
Prospects of using lanthanide superconductors in nanotechnology are considered. 相似文献

Hydrogen-free amorphous and nanocrystalline films were prepared by magnetron sputtering of the SiC or Si targets. Mechanical properties (hardness, elastic modulus, intrinsic stress) and film structures were investigated in dependence on the substrate bias and temperature. It was found that both hardness and elastic modulus of all amorphous a-SiC films prepared at different substrate temperatures and biases are always lower than those for bulk α-SiC single crystal while the hardness of partially crystalline SiC films is higher and the elastic modulus lower than those for α-SiC one. In contrast, both hardness and elastic modulus of all amorphous Si films are always lower than those for nanocrystalline Si films which show approximately the same value as the Si single crystal. 相似文献
