鋁合金 中溫拋光染色封閉劑

一、開槽參數(shù) (tank set up parameters)

DBR-703：5～8g/L

二、控制參數(shù) (coolling parameters)

Ni2+：0.8～1.5g/l      PH：5.5～6.2

溫度 (Temperature) ：50～70℃

時間 (Time) ： 0.8～1.2um/ min                       

三、維護和管理 (maintenance and coolling)

1.每天檢測槽液中的Ni2+濃度及pH值；并根據(jù)分析結(jié)果及時補加調(diào)整。處理100m2約消耗DBR-703：0.2～0.3Kg。

Detection of the bath conceation of Ni²⁺ and PH value, according to the analysis results to adjust and add;

the DBR-703 of consumption is 0.2～0.3Kg for each 100m² treatment.

2.正常生產(chǎn)時PH值呈上升趨勢，每班需檢測一次PH值并用稀醋酸/稀硫酸調(diào)整；如PH值偏低則說明帶入酸水過多，需控制染色前水洗PH值≥4.5，此時需用稀氨水/稀氫氧化鈉調(diào)整。

The PH value rising when producing, it should measured PH value and used Dilute acetic / sulfuric acid  adjusted; rinsing acidic water is brought too much if the PH value is low, it need to cool the rinsing water PH value ≥ 4.5 before dying color. Need to use dilute ammonia water / dilute sodium hydroxide to adjust.

3.長期生產(chǎn)槽液或多或少會有沉淀物產(chǎn)生，要定期過濾或倒槽清理沉淀物。

Producing bath will produced more or less white precipitate for a long time, need to filter or reverse the sealing solution.
