OPERATION
操作
It is important that the instructions in this Technical Data Sheet are carefully followed. Operation outside the des- ignated ranges could result in defective deposits and plating rejects. Specific gravity, temperature and pH values ?should be controlled daily. The use of automatic dosing pumps is recommended. Small, frequent additions are recommended. In no instance should the amount of replenish addition be more than the make up quantity. When making additions, it is preferable to dilute the component with water or plating solution and distribute it uniformly ??over the surface of the solution.
務(wù)必認(rèn)真遵守本技術(shù)數(shù)據(jù)表中的說明。超出指定范圍的操作可能導(dǎo)致有缺陷的沉積物和鍍層不合格。應(yīng)每天控制比重、溫度和pH值。建議使用自動加藥泵。建議少量、頻繁添加。在任何情況下,補(bǔ)充添加的數(shù)量都不應(yīng)超過補(bǔ)充數(shù)量。添加時,最好用水或電鍍?nèi)芤合♂尦煞?,并將其均勻分布在溶液表面?/p>
Pre-treatment
預(yù)處理
Prior to plating,the work surface should be pre-treated in a dilute hydrochloric acid (5% HCl) dip.
電鍍前,應(yīng)在稀鹽酸(5%HCl)浸液中對工作表面進(jìn)行預(yù)處理。
Post Treatment
后處理
?
After plating, an acidic drag out rinse is recommended to avoid precipitation of metal salts. ?The pH of the drag out rinse should be adjusted to 3.0 to 4.0 with hydrochloric acid.
電鍍后,建議進(jìn)行酸性沖洗,以避免金屬鹽沉淀。應(yīng)使用鹽酸將拖出沖洗液的pH值調(diào)節(jié)至3.0至4.0。
Maintenance
維護(hù)
The ENLOY SHADOW operating solution should be analyzed periodically for ENLOY SHADOW SN and ENLOY SHADOW NA and replenished as required. ?Analytical procedures for these two components are available from ?Enthone-OMI.
