铬王FC-1890长效铬雾抑制剂
FC-1890是我公司开发的第二代铬雾抑制剂。
其特点:
1.有良好的水溶性,可与50%的水相溶。
2.加入很少量,即可达到低的表面张力(每公升250毫克，即可达到22.16mN/m)
3.工作条件下的持久性,高电流密度能顺利迅速溶于电介质中。
4.抑雾剂在电解液表面形成薄薄的泡沫层,就象附加过滤器能有效阻止酸雾溢出时不使报鸣气增多发生爆鸣。
５.克服了其他铬雾抑制剂对镀铬层表面光洁度的影响。使表面光洁度更高。
６.能迅速从铬镀层上脱落，大大减少工件带出量损失，因而作用时间更长。
Chrome King FC-1890 Permanent Chrome-fog Depressant
FC-1890 is the second generation chrome-fog depressant developed by our company.
Its characteristics are shown as the following:
1. Good water solubilizing, it can dissolve in 50% water.
2. Low surface tension with small quantity (250mg/kl=22.16mN/m)
3. Sustaining under the working condition, it can dissolve in dielectric quickly with high current density.
4. Depressant forms a thin foam layer on surface of cell liquor, it seems that the additional filter can effectively stop acid fog from overflowing to produce ringing.
5. Overcome the effects of other chrome-fog depressant to degree of finish of chrome-plating, and make the finish degree of surface much more higher.
6. It can drop from chrome-plating layer quickly and greatly reduce the loss of workbelt output, so the effecting time becomes longer.
