一、開槽參數(shù) (tank set up parameters)
硫酸亞錫(tin sulfate):5~10 g/l 硫酸鎳(nickel sulfate):18~25 g/l
試劑硫酸Sulfuric acid ( reagent) :15~20g/l DBR-602:20~25 g/l
二、控制參數(shù) (coolling parameters)
硫酸亞錫 (tin sulfate):3~10 g/l, 溫 度 (Temperature):20±2 ℃
硫酸鎳 (Nickel sulfate):15~25 g/l 電 壓 (Voltage):12~18 V
游離硫酸 (Free Sulfuric acid):15~20 g/l PH:0.8~1.2
時(shí)間 Time:1~10min(根據(jù)顏色深淺確定, depends on the color density)
三、維護(hù)和管理 (maintenance and cool)
1、根據(jù)化驗(yàn)結(jié)果來確定添加相應(yīng)的組分,槽液酸度一般控制在PH值在0.8—1.2。一般情況下,各著色組分消耗在著色材料為400-600m2/噸時(shí):硫酸亞錫 2~3.5kg/ton 硫酸鎳 1~2.5kg/ton 試劑硫酸1~1.5kg/ton DBR-602 :2~3.5kg/ton
The consumption of the solution is depending on the testing result, the PH value should be coolled between 0.8 – 1.2. Under normal situation, the consumption of the chemical for aluminium with surface area between 400 – 600 m2 /ton are: Tin sulfate : 2~3.5 kg/ton, Nickel sulfate 1~2.5 kg/ton, Sulfuric acid reagent 1~1.5 kg/ton, DBR-602:2~3.5 kg/ton
2、嚴(yán)格控制槽液溫度,溫度過高著色色底發(fā)暗、不鮮艷。溫度過低著色困難。
The tank liquid temperature should be tightly coolled. The base color will become darker with higher temperature; coloring becomes difficult if the temperature is too low.
3、配置過濾裝置定期清理槽中沉淀物,以免沉渣過多影響著色
The tank solution should be filtered regularly, to ensure good coloring result.
