镀锌层

The results show that there is intensive synergistic effect among cetyltrimethylammonium bromide, benzalacetone and polyethylene glycol. A bright and compact nanocrystalline zinc was produced due to the coexistence of such three additives.

结果表明，十六烷基三甲基溴化铵、4-苯基-3-丁烯-2-酮和聚乙二醇三种添加剂之间具有较强的协同作用，采用三者组成的混合添加剂可制备出光亮致密的纳米晶锌镀层。

The existence of titanium dioxide and titanyl sulfate reduces the corrosion of zinc deposits.

结果发现：钛的加入能明显提高钝化膜的耐蚀性，这是由于钝化膜中形成二氧化钛和硫酸氧钛，它们掺杂在钝化膜及其腐蚀产物中，有效抑制了锌镀层的腐蚀。

The present invention is particularly applicable but not limited to the treatment of alkaline and acidic non-cyanide zinc electrodeposits to impart improved corrosion resistance and a decorative appearance to the treated substrate.

本发明特别适用但不限于酸性和碱性治疗非氰化锌镀层至传授提高耐蚀、装饰物外观的待遇。

The bath compositions of trivalent chrome black passivation for zinc-iron alloy coating were optimized by orthogonal test method.

采用正交试验法对锌-铁合金镀层三价铬黑色钝化工艺进行优化，并研究了工艺参数对钝化膜外观和耐蚀性等影响。

ELV and RoHS compliant process trivalent chromium passivate, an attractive yellow rainbow finish on zinc deposits, over 96 hours to white salt.

三价铬环保产品，环保产品符合ELV和RoHS指令，可在锌镀层表面形成彩色钝化膜。盐雾达96小时。

The uncertainty for determination of iron concentration in zinc-iron coating of galvaneal by chemical method was evaluated.

对用化学法测定锌铁合金钢板镀层铁含量测量结果的不确定度进行评定，分析了该方法测定过程的不确定

Carving gravure of business card printing and membership card making production and offset business card printing and membership card making, and so on are very different, first of all the manuscripts submitted to approx 10 times, the perimeter line by hand is decisived on top of a piece of zinc tablet with a smaller machine to get an outside line back into the original large carved in a piece about an inch of eight brass, and copper strip it is some anticorrosive toppedwith films, because of copper strip is triggered from the perimeter line, so the rough body by hand for the film, when removed, and then use the medicine to the erosion of deep water, and proto-end knife with a magnifying glass and, thetolerant to the edge, sharp corners repaired, such as location on a layer of chrome, it's a printing plate.

雕刻凹版的制卡和会员卡制作制作与柯式制卡和会员卡制作等有很大的分别，首先把来稿放大约十倍，把外围线用手工刻划在一块锌片之上，再用一部缩细机械把外线缩回原大刻在一块约八份一寸的铜片上，而这件铜片上是涂有一些防腐蚀薄膜的，因为铜片只是勾上字的外围线，所以要用手工将粗身地上的薄膜刮去，然后用药水将印纹蚀深，最后仍要用放大镜及雕刻刀，耐性地将线边、尖角等位置修好，再镀上一层铬，这印版便大功告成。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
