一、開槽參數(shù) (tank set up parameters)
硫酸 (Sulfuric acid):150~180g/l
DBR-501: 35±5 g/l
二、控制參數(shù) (coolling parameters)
游離酸Free acid 145~180g/l
AL3+:1~30g/l DBR-501: 35±5 g/l
電流密度 Current density :1.0~2.0A/dm2
電壓 Voltage :10~18 V
溫度 Temperature :28±2℃
三、維護和管理 (maintenance and cool)
1.標準膜(10um)下,DBR-501的消耗3~4kg/ton,膜厚增加,消耗相應(yīng)增加。
In normal anodizing film thickness(10um), the consumption of DBR-501 is 3~4 kg/ton; the consumption will increase according to film thickness.
2.DBR-501溶于冷水較慢,生產(chǎn)過程中開缸或添加時應(yīng)先溶解后再加入槽中,以免有效物沉于槽底,造成消耗過大。
DBR-501 is difficult to dissolve in cold water; the chemical should be dissolved first in other medium before adding to the tank, this will prevent condensation and waste.
