有机硅抑制剂在铝酸盐溶液蒸发中的应用

加热或蒸发结晶的溶液时,导热性差的结垢组份会在换热表面上同时结晶析出,从而使换热器产能急剧下降。延缓换热器结垢速度的方法之一是添加表面活性物质,包括有机硅溶液,如聚乙烯硅酮钠(ΓКЖ-10)和聚甲基硅酮钠(ΓКЖ-11)。应用一般表面活性物质作氧化铝生产中结垢的抑制剂,在高温(>150℃)、高苛性碱浓

齐留宾斯克电极厂电动焦油捕集器的改进

齐留宾斯克电极厂碳素电极焙烧工段安装有30室焙烧炉。工艺烟气经过专门的阀引入水平地下烟道,再进入C7.2型电动焦油捕集器进行收集。烟气温度80℃,焦油含量在300～800毫克/米~3之间,净化后的烟气(焦油浓度10～15毫克/米~3以下)通过烟囱排至大     

电极表面处理和电极材料对微型点焊时电极粘附的影响

研究了电极表面处理和电极材料对镀镍钢板和镍板微型点焊时电极粘附的影响。结果表明：电极表面涂敷TiC后能提高CuCrZr电极和GlidCop60电极的抗粘附性能，其原因是涂层中的TiC能阻碍电极和镀镍板之间的局部焊接；GlidCop60电极的抗粘附性能优于CuCrZr电极的抗粘附性能，其原因是弥散分布于GlidCop60电极中的Al2O3能阻碍电极和镀镍板之间的局部焊接。

贯通式输送带-贮料库

在加工箱体零件的自动线系统中,贯通送带—贮料库获得愈来愈广泛的应用。贮料库(如图1)应用于下述情况:(1) 作为装料装置1和卸料装置2;(2) 用于连接位于同一平面的和顺序的自动线,其输送方向分为一致的(如送带—贮料库3直接连接的自动线Л_1和,平行的(如自动线Л_2和有输送带—贮4的自动线Л_3)或垂直的(如自动线有输送带—贮料库5的自动线Л_5);(3) 用于分开和连接系统中平行工作多支线自动线的各支线,如借助输送带料库6将自动线Л_6分成支线Л_6/1％和Л_6/2,过输送带—贮料库7将它们与自动线Л_7连     

THE PREPARATION AND CHARACTERISTICS STUDY OF TiNxOy SPECTRAL SELECTIVE ABSORBING FILM BY MAGNETRON SPUTTERING

Spectral selective absorbent film is a crucial factor for the solar heating device. There are many kinds of spectral selective absorbing film made by different ways. TiNxOy thin film with excellent spectral selecting absobent property were successfully prepared by DC magnetron sputtering with Ar as working gas, N2 and O2 as reactive gas, 99.9% titanium as the target and is copper slice as the substrate. In this article, the optical characteristics and microstructure of TiNxOy thin film were studied. Inputing O2 can decrease the reflection of the visible lights, and double layer film can get good absorption for solar energy.     

Advances in the research of nitrogen containing stainless steels

The current status of nitrogen containing stainless steels at home and aboard has been introduced. The function and existing forms of nitrogen in the stainless steels, influence of nitrogen on mechanical properties and anti-corrosion properties as well as the application of nitrogen containing cast stainless steels were discussed in this paper. It is clear that nitrogen will be a potential and important alloying element in stainless steels. And Argon Oxygen Decarbonization (AOD) refining can provide an advanced manufacture process for nitrogen containing stainless steels with ultra-low- carbon and high cleanliness.
