鋁合金 高溫封閉劑

一、開(kāi)槽參數(shù) (tank set up parameters)

DBR-704：5～10g/L

二、控制參數(shù) (coolling parameters)

Ni2+：0.8～1.3g/l      PH：5.3～5.8

溫度 (Temperature) ：85～95℃

時(shí)間 (Time) ： 1.0～1.5um/ min                          

三、維護(hù)和管理 (maintenance and coolling)

1.每天檢測(cè)槽液中的Ni2+濃度及pH值；并根據(jù)分析結(jié)果及時(shí)補(bǔ)加調(diào)整。處理100m2約消耗DBR-704：0.2～0.3Kg。

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

the DBR-704 of consumption is 0.2～0.3Kg for each 100m² treatment.

2.正常生產(chǎn)時(shí)PH值呈上升趨勢(shì)，每班需檢測(cè)一次PH值并用稀醋酸/稀硫酸調(diào)整；如PH值偏低則說(shuō)明帶入酸水過(guò)多，需控制染色前水洗PH值≥4.5，此時(shí)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(zhǎng)期生產(chǎn)槽液或多或少會(huì)有沉淀物產(chǎn)生，要定期過(guò)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.
