一、開(kāi)槽參數(shù) (tank set up parameters)
NaOH :50~60g/L
DBR-401:20~30g/L(水劑 / liquid)
二、控制參數(shù) (coolling parameters)
游離堿(free alkali) :40~55g/L
AL3+:15~25 g/L
溫度 (Temperature) :45~60℃
時(shí)間 (Time) :3~5 min
三、維護(hù)和管理 (maintenance and cool)
1.每天分析槽液濃度并根據(jù)結(jié)果及時(shí)調(diào)整,補(bǔ)加比例為氫氧化鈉:DBR-401=5:1。處理100m2鋁材約消耗DBR-401:0.5~1.0kg。
Analysis the bath conceation one time a day, according to the analysis results adjust to add the proportion of sodium hydroxide:DBR-401=5:1; the consumption of DBR-401:0.5~1.0 kg for each 100 m2 aluminium treatment
2.正常生產(chǎn)時(shí)因帶出損耗導(dǎo)致液面降低補(bǔ)加水則需添加相應(yīng)比例的氫氧化鈉和DBR-401。
When it’s in normal production. the loss will lead to reduce the surface water if you add water ,you need to add the appropriate proportion of sodium hydroxide and DBR-401.
3.不生產(chǎn)時(shí)加蓋槽液以防污染。并保溫≥35℃以防鋁離子水解。
Affix the bath to prevent contamination when stop produce. Keep temperature of solution≥35℃,to prevent the aluminum ion hydrolysis.
