碳酸锌

The simthsonite name derives from English mineralogist James Smithson(1765-1829), who identified two different minerals smithsonite from hemimorphite in 1807, both have long been confused as same mineral, called calamine, used to produce brass, mixed with cupper.

18世纪末在欧洲，人们称用于冶炼黄铜的，和铜矿混在一起的锌矿石为菱锌矿，实际上那是的"菱锌矿"里面混杂了含水硅酸锌、异极矿和碳酸锌。由于产状大多时葡萄状，所以很难区分两种矿物。

The antibacterial activity of Calamine is decided by the content and particle size of zinc oxide,and has nothing with zinc carbonate.

炉甘石抑菌活性主要取决于氧化锌的含量和粒径大小，与碳酸锌无关。

Uses in the paint, the printing ink, the varnished cloth coloration, the printing industrial used dye printing reserving agent, uses in the neutral cowhide glue in the matches industry the acidity, increases the gummy effect, the pharmaceutical industry serves as the adhesive plaster raw material, in addition also uses in the pigment zinc chrome yellow, the zinc acetate, the zinc carbonate, the zinc chloride and so on manufacture, the synthesis methyl alcohol catalyst, the synthetic ammonia sweetening agent, the glass and glazes the production, the pellet thin active zinc oxide (about particle size 0.1um) may serve as plastic and so on polyolefine and polyvinyl-chloride light stabilizers, the zinc oxide also uses in pressing, the photochemical catalysis, the electro-optic sensitively extremely, domains and so on coating, color television development.

用于油漆、油墨、漆布的着色，印染工业用的印花防染剂，在火柴工业中用于中和牛皮胶的酸性，增加胶粘效果，医药工业用作橡皮膏的原料，此外也用于颜料锌铬黄、醋酸锌、碳酸锌、氯化锌等的制造，合成甲醇的催化剂，合成氨的脱硫剂，玻璃和釉料生产，颗粒细的活性氧化锌（粒径0.1um左右）可用作聚烯烃和聚氯乙烯等塑料的光稳定剂，氧化锌也用于压敏、光催化、光电极、涂料、彩电显影等领域。

Main production direct method zinc oxide, indirect method zinc oxide, zinc carbonate, zinc oxide in a total production of 4000 tons.

主要生产直接法氧化锌，间接法氧化锌，碳酸锌，年生产各种氧化锌共计4000吨。

The results, obtained by chemical analysis, Xray diffraction and scanning electron microscopical observation of the process concerned and products, show that the process flowsheet is simple and can be used to prepare basic zinc carbonate for producing activated zi...

结果表明：该工艺过程简单，得到可制备活性氧化锌的碱式碳酸锌；磁场作用对碱式碳酸锌的结构及热解产物的粒度产生了有利于活性氧化锌制备的影响。

Nanocrystal basic zinc carbonate was a new type of basic zinc carbonate.It could be used as skin protective agent in the pharmaceutical industry.It also could be used as basic raw materials in the production of cosmetics.

纳米微晶碱式碳酸锌是一种新型的碱式碳酸锌，在医药行业可用作皮肤保护剂，在化妆品生产中用作基础原料。

The good corrosion resistance of hot dip galvanized steel products in nature environments is due to the formation of a protective basic zinc carbonate film on the surface of the zinc coatings.

热浸镀锌表面会生成具良好保护性的碳酸锌膜，保护锌材在一般环境中不致腐蚀太快。

The particle size of nanosized zinc carbonate is between 5 nm and 40 nm, and its kinetic parameters of thermal decomposition reaction---activation energy E and reaction order n are 110 kJ.mol－1 and 0.9, respectively.

用透射电子显微镜观察1号、2号和3号纳米碳酸锌粒子，可以看到粒子形状为椭球形，大小均匀，分散性好，没有明显的团聚现象，粒径分别在20～40nm、6～10nm、5～8nm之间；并且用微粒度测定仪测得了粉体的粒度分布图，表明纳米碳酸锌粒子的分布很窄。

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。
