一、开槽参数 (tank set up parameters)
硫酸亚锡(stannous sulfate):10~15g/l
硫酸 (sulfuric acid):15~20 g/l DBR-601:20~25 g/l
二、控制参数 (coolling parameters)
硫酸亚锡(stannous sulfate):10~15g/l
游离酸(free acid): 15~18g/l PH (value): 0.8~1.2
温度(Temperature): 18~22℃ 时间(Time): 0.5~10min
三、维护和管理 (maintenance and cool)
1.每天检测槽液浓度并按分析结果及时调整,硫酸亚锡和DBR-601按1:2比例添加。每处理100m2约消耗DBR-601:0.4~0.6Kg。槽液的总酸度控制在30~40g/l。
Detection of the bath conceation one time a day, according to the analysis results to adjust; it added stannous sulfate and DBR-601 can be 1:1.5~2 ,the DBR-601 of consumption is 0.4~0.6Kg for each 100m2 treatment aluminum. Total acidity cool in 30 ~ 40g / l.
2.添加硫酸亚锡时须同DBR-601先混合再溶解于槽液中;向槽中补加纯水时,必须在搅拌下缓慢加入,以防止局部硫酸亚锡水解,导致槽液发浑。
When added stannous sulfate, it should be mixed with the DBR-601 first and then dissolved in the bath , added water, you must join slowly in the stirring, to prevent partial hydrolysis of stannous sulfate, tending to bath volatility .
3.槽液对铜杂质较敏感,清理导电铜座时须特别注意不得污染槽液。
Producing bath will produced more or less white precipitate for a long time , you need to filter or reverse the bath to clean sediments regularly. Affix the bath to prevent contamination when stop produce
