铝合金中温厚膜封闭剂

产品信息

产品详细

一、开槽参数 (tank set up parameters)

DBR-70258g/L

二、控制参数 (controlling parameters)

Ni2+0.81.5g/l        PH5.56.5

温度 (Temperature) :50~70℃

时  间 (Time) : 0.8~1.2um/ min                        

三、维护和管理 (maintenance and controlling)

1.每天检测槽液中的Ni2+浓度及pH值;并根据分析结果及时补加调整。处理100m2约消耗DBR-702:0.2~0.3Kg。

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

The DBR-702 of consumption is 0.20.3Kg for each 100m2 treatment.

2.正常生产时PH值呈上升趋势,每班需检测一次PH值并用稀醋酸/稀硫酸调整;如PH值偏低则说明带入酸水过多,需控制染色前水洗PH值≥4.5,此时需用稀氨水/稀氢氧化钠调整。

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 control the rinsing water PH value ≥ 4.5 before dying color. Need to use dilute ammonia water / dilute sodium hydroxide to adjust.

3.长期生产槽液或多或少会有沉淀物产生,要定期过滤或倒槽清理沉淀物。

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