摘要
光亮剂的阴极极化行为与镀层的性能有对应的关系,研究光亮剂的极化行为是辅助筛选光亮剂的一种有效的方法。考察了几种具有代表性的镀银光亮剂的用量及其复配对极化行为的影响。结果表明:含硫主光亮剂去极化;含羟基和磺酸基载体光亮剂增大极化;含硫主光亮剂和含磺酸基载体光亮剂复配有协同作用和起去极化作用。
The effects of dosage and combination of several represent-ative silver-plating brighteners on the polarization behavior were investigated.Results show that S-containing primary brighteners are capable of retarding polarization,while auxiliary brighteners containing hydroxyl and sulfonic acid group are capable of enhan-cing polarization.The S-containing primary brighteners and the auxiliary brighteners containing sulfonic acid group had synergis-tic effects and were capable of retarding polarization.
