鋁合金常溫快速封閉劑

一、開槽參數(shù) (tank set up parameters)

DBR-701：4～6g/L         

二、控制參數(shù) (coolling parameters)

Ni2+：0.8～1.5g/l        Fˉ：0.2～0.6g/l

PH：5.5～6.5          溫度 (Temperature) ：20～30℃

時間 (Time) ： 1.2～1.8um/min                      

三、維護和管理 (maintenance and coolling)

1、正常情況下槽液工藝參數(shù)：Ni²⁺=0.8~1.2g/l 、F^-=0.3~0.6g/l、PH   =5.5~6.5。

Under normal condition, the tank liquid parameter should be Ni²⁺=0.8~1.2g/l 、F^-=0.3~0.6g/l、PH   =5.5~6.5.

2、根據(jù)化驗槽液的結果來確定添加量。一般情況下每生產一噸料約消耗DBR-701：1.0~1.5kg（以10um計）。

The amount of solution to be added is depending on the testing result, under normal condition, each ton of aluminium profile consuming DBR-701: 1.0kg (for 10um)

3、生產過程中控制pH值在5.5～6.5，過高用稀醋酸（或稀氫氟酸）調節(jié)其pH值、過低用稀氫氧化鈉（或稀氨水）溶液調節(jié)其pH值。

Manage to cool the PH value between 5.5～6.5 during the production, If the PH is too much high then could adjust by acetic acid , adjusting by the ammonia water to if the PH is too much low.
