日前,由德国汉高集团投资的全球最大的粘合剂和金属表面处理剂工厂在上海化学工业园奠基。汉高为这个项目起了个很中国的名字“龙项目”。
2006年就来到中国的欧阳德(英文名字Jan-Dirk Auris),从2008年开始担任汉高亚太区总裁兼粘合剂技术亚太区总裁,2011年起回到德国总部任汉高粘合技术执行副总裁,成为汉高全球管理委员会成员。 相似文献

正自十二五以来,国家一再严令关闭污染严重的"十五小"企业,其中第十二项就是电镀,传统电镀工艺复杂、耗能大、排放物污染严重,因其高污染、高能耗、高伤亡的特征给自然环境和人们的生活带来极大的危害。科技的发展也对金属表面处理技术的要求越来越高,时代呼唤一种创新型高科技环保金属表面处理技术替代原有的电镀工艺,而北京中科创新科技发展中心(www.bjzkcx.net)开发出的"新 相似文献

It is a challenge for passive RFID tags to be mounted on the surface of metal because the parameters of tag antennas, such as the impedance matching, the radiation efficiency and the radiation pattern, are seriously affected by the metallic surface. This paper presents the characteristics of the dipole-like antennas of ultra high frequency (UHF) radio frequency identification (RFID) tags that are placed close to metallic surfaces. The finite element method (FEM) and method of moment (MoM) were used to simulate the changes of the antenna parameters near the metallic surface. Two typical dipole-like antennas close to the metallic surface, a closed loop antenna and a loaded meander antenna, were modeled, and the performance was evaluated. Experiment was carried out and the results were in good agreement with the simulation, showing that a distance of 0.05λ-0.1λ (λ is the free space wavelength) from the metallic surface could make the dipole-like UHF RFID tag performance be acceptable. 相似文献
