一、开槽参数 (tank set up parameters)

H₃PO₄ ： 50~60%    H₂SO₄ ： 40~50%

     AL³⁺：20g/L         DBR~301 : 20~30g/L

二、控制参数 (controlling parameters)

H₃PO₄ ： 50~60%    H₂SO₄ ： 40~50%

     AL³⁺ ：  20~50g/l

比重（specific gravity）：   1.76～1.84 g / cm³

温度 (temperature): 95℃～110℃                          

时间 (time) ：0.5～5min

三、维护和管理 (maintenance and control)

1.每天测量槽液比重并根据结果补加酸及时调整，偏高用磷酸调整；偏低用硫酸调整。处理100m2铝材约消耗无烟化学抛光剂DBR-301：0.2～0.4kg。

  Measure the bath of the specific gravity and according to the analysis results adjust to add acid, when it’s high you can use nitrate to adjust; low can adjust with sulfuric acid. the consumption of DBR-301：0.2～0.4kg for each 100m2 aluminium treatment。

2.正常生产时消耗补加可按磷酸：硫酸=1：1。无烟化学抛光剂DBR-301补加为两酸用量的1/100。

When normal production of the consumption, you can add phosphoric acid : sulfuric acid = 1:1。add the amount of DBR-301 for the two acid 1 / 100。

3.两酸具较强的腐蚀性，操作时须佩戴耐酸碱手套及防护围裙。不生产时加盖槽液以防吸水。

The phosphoric acid，sulfuric acid with strong acid corrosion, when operations are required to wear gloves and protective aprons. Covered the bath to prevent humidity when stop produce.
