一、开槽参数 (tank set up parameters)
硫酸亚锡(tin sulfate):5~10 g/l 硫酸镍(nickel sulfate):18~25 g/l
试剂硫酸Sulfuric acid ( reagent) :15~20g/l DBR-602:20~25 g/l
二、控制参数 (coolling parameters)
硫酸亚锡 (tin sulfate):3~10 g/l, 温 度 (Temperature):20±2 ℃
硫酸镍 (Nickel sulfate):15~25 g/l 电 压 (Voltage):12~18 V
游离硫酸 (Free Sulfuric acid):15~20 g/l PH:0.8~1.2
时间 Time:1~10min(根据颜色深浅确定, depends on the color density)
三、维护和管理 (maintenance and cool)
1、根据化验结果来确定添加相应的组分,槽液酸度一般控制在PH值在0.8—1.2。一般情况下,各着色组分消耗在着色材料为400-600m2/吨时:硫酸亚锡 2~3.5kg/ton 硫酸镍 1~2.5kg/ton 试剂硫酸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、严格控制槽液温度,温度过高着色色底发暗、不鲜艳。温度过低着色困难。
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、配置过滤装置定期清理槽中沉淀物,以免沉渣过多影响着色
The tank solution should be filtered regularly, to ensure good coloring result.
