A View on Wear Mechanism of Metallic Card Clothing

The wear mechanism of metallic card clothing, used in textile industry, was analyzed. A fast wear test for metallic card clothing racks was developed, which was used as collecting the wear metal particles. The failure type of card clothing was analyzed by the mean of scanning electron microscopy （SEM） and ferro-spectrum technology. The results show that the main wear mechanism of metallic card clothing is low load and high repetition interval fatigue wear caused by friction force between fiber and metal wire teeth. The appropriate quenching microstructure, which improves the wear resistance of the metallic card clothing rack is also discussed.

天然植物养护剂对番茄、黄瓜生殖生长影响初探

使用不同的配比浓度将壳聚糖和黄腐酸配制成不同的天然植物养护剂,观察其对于番茄和黄瓜生殖生长过程中的成花生理和果实中部分营养成分含量的影响.结果表明:不同浓度和配比的养护剂对2种作物的生殖生理均有不同的影响,适当的配方可以使番茄首花出现时间提前和提高黄瓜的雌雄花比,并使黄瓜果实中可溶性糖提高7.93%,有机酸提高8.77%,番茄果实中维生素C提高2.31%.证明合适的壳聚糖和黄腐酸配比的植物养护剂可促进植物生殖生长,并可提高果实质量.     

Gd表面磁控溅射保护膜耐腐蚀性能研究

为了提高磁致冷材料Gd在腐蚀介质中的耐腐蚀性,采用磁控溅射技术,在磁致冷材料Gd表面溅射一层保护材料(Al、Cu),研究在不同介质中对Gd腐蚀行为的影响.结果表明:磁控溅射Al膜对Gd起了明显的保护作用;Cu膜由于与基体Gd结合较差,未起到保护作用.     

瑶族传统服饰工艺的传承与发展

瑶族民间传统服饰工艺主要有纺织、染色、刺绣、织锦等。过去,瑶族传统服饰都是由瑶族妇女使用传统服饰工艺制作的。20世纪80年代后,由于受到现代化的发展和经济全球化的冲击,瑶族传统服饰工艺濒临失传。继承和发展瑶族传统服饰工艺成为保护瑶族非物质文化遗产的重要内容之一。     

Formation mechanism of the graphite-rich protective layer in blast furnace hearths

A long campaign life of blast furnaces is heavily linked to the existence of a protective layer in their hearths. In this work, we conducted dissection studies and investigated damage in blast furnace hearths to estimate the formation mechanism of the protective layer. The results illustrate that a significant amount of graphite phase was trapped within the hearth protective layer. Furthermore, on the basis of the thermodynamic and kinetic calculations of the graphite precipitation process, a precipitation potential index related to the formation of the graphite-rich protective layer was proposed to characterize the formation ability of this layer. We determined that, under normal operating conditions, the precipitation of graphite phase from hot metal was thermodynamically possible. Among elements that exist in hot metal, C, Si, and P favor graphite precipitation, whereas Mn and Cr inhibit this process. Moreover, at the same hot-face temperature, an increase of carbon concentration in hot metal can shorten the precipitation time. Finally, the results suggest that measures such as reducing the hot-face temperature and increasing the degree of carbon saturation in hot metal are critically important to improve the precipitation potential index.
