氧化锌

It is an important consideration in purification circuits that removal cadmium completely prior to cobalt cementation, because cadmium can inhibit basic zinc sulphate to adsorb on the surface of zinc dust.

镉可以起到阻止碱式硫酸锌或氢氧化锌吸附在锌粉表面的作用。欲加速钴的置换和提高置换效率，必须形成锌-钴合金或锌-镉合金。

Companies engaged in production of zinc oxide has been nearly 20 years of history, is the professional production of zinc oxide manufacturers.

公司从事氧化锌生产已有近二十年的历史，是氧化锌生产的专业厂家。

The invention discloses a synthetic using method of smelting high-furnace dust, which comprises the following steps: grinding the high-furnace dust with 1.5-15% zinc; proceeding magnetic cobbing; reclassifying to obtain the refined ferric ore; disposing ore tail through waste acid of titanium dioxide with 15-30% sulphuric acid; transmitting the zinc oxide in the solution at zinc sulfate pattern; separating solid and liquid solution through lime; obtaining refined zinc ore through S2-, CO32-, HCO3- ion; floating the immersed slag through neutral oil.

一种炼铁高炉炉尘资源综合利用的方法，含锌1.5％～15％的高炉炉尘经磨矿、磁选、重选回收铁矿物获得铁精矿，选矿尾矿用含硫酸15％～30％的钛白废酸处理，使其中的氧化锌以硫酸锌的形式转入溶液中，固液分离得出的溶液用石灰中和除铁后，再用S2-、CO32-、HCO3-离子沉锌获得锌精矿，浸出渣用中性油浮选获得炭精矿。该方法将钛白废酸和高炉炉尘结合在一起，使之成为互为所需的原料和试剂，有效地将两种废弃物变成了有价资源，较好解决了环境污染问题，同时又能产生好的经济效益。

Effects of oxidization conditions of zinc vapor at high temperature on the crystal morphologies of ZnO and morphology change laws are investigated.

实验研究了锌蒸气高温气相氧化条件对氧化锌结晶形貌的影响以及形貌变化的规律。

The effects of conditions of oxidizing zinc vapor at high temperature on the crystal morphologies of ZnO were investigated.

摘 要：研究了锌蒸气高温气相氧化条件对氧化锌结晶形貌的影响结果。

Results :The pain reaction of CPC group is much lighter than Zinc bloom Clove oil lodoform Paste Gutta Percha Point group and the successful rate of CPC group is higher than Zinc bloom ...

结果：自固化磷酸钙根管充填剂治疗组根充后反应明显轻于氧化锌丁香油碘仿糊剂牙胶尖根充治疗组，临床治疗成功率高于氧化锌丁香油碘仿糊剂牙胶尖根管充填组(P.05)。

ZnO nanoparticles were surface-modified by surfactants such as span-60,oleic acid,sodium laurate,andx as surface-modifier,and were added at the concentration of 0.5% in lquid paraffin to perform sedimentate test.

以山梨糖醇酐三油酸酯(span-60)、油酸、月桂酸钠和氟碳(C—Fx为表面活性剂对纳米氧化锌进行表面修饰，将修饰过的纳米氧化锌添加到液体石蜡中，使其质量分数为0.5%，进行沉降实验。

It was showed that the nanoparticle ZnO may shorten the sulfurization time and improve mechanics performance of the rubber.

结果表明，和普通氧化锌在同等用量时，纳米氧化锌可以缩短胶料的硫化时间，提高胶料的力学性能。

It utilizes the NH3-NH4CL solution to smelt the flowers of zinc and the ash from the lead factory and the zincic industry waste residue and so on.

本发明公开的&一种湿法炼锌工艺&用NH3-NH4CL溶液浸出氧化锌、锌焙砂、铅厂烟灰、含锌工业废渣。

The results were analyzed statistically.Results The incidence of post obturation pain after 1 day in zink oxide paste group was significantly higher than that two groups. The pain occurrence happened 5 or 30 days root canal filling were no difference on them. No statistical difference was observed in success rate on them after 1 year.

结果 Vitapex组和新型根管糊剂组术后1天的疼痛反应较氧化锌组糊剂少，且有显著性差异；5天、30天的疼痛反应则无明显差异；1年后氧化锌组的尖周愈合程度较Vitapex组和新型根管糊剂组差，但已无统计学差异。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
