羽杰科技水溶性银保护剂还可称做的银防氧化剂、银抗氧化剂, 镀银防变色等。

 

Yujie technology water soluble silver protector can also be called silver antioxidant, silver antioxidant, silver plating anti discoloration and so on.

 

羽杰科技水性银保护剂含有可溶于水的氧化抑制剂,能在金银表面形成一层极薄的纳米保护膜, 该保护膜无毒、无刺激性,可用于珠宝、饰品、电子器件等饰件。

 

Yujie technology water-based silver protector contains water-soluble oxidation inhibitors, which can form a very thin nano protective film on the surface of gold and silver. The protective film is non-toxic and non irritating, and can be used for jewelry, jewelry, electronic devices and other accessories.

 

金银件经银保护剂处理后可显著提高盐雾效果和防变色作用,短时间的热处理300分钟以下对保护层的性能影响不大,稳定性高,满足替代进口同类产品的条件。

 

After treated with silver protectant, the effect of salt spray and anti discoloration of gold and silver parts can be significantly improved. Short time heat treatment of less than 300 minutes has little effect on the performance of the protective layer and high stability, meeting the conditions of replacing imported similar products.

一、配制条件:

 

I. preparation conditions:

 

配比:50-250Ml/L(视要求高低)

 

Ratio: 50-250ml / L (depending on requirements)

 

温度:40-50度

 

Temperature: 40-50 degrees

 

浸渍时间:30秒-3分钟

 

Immersion time: 30 seconds - 3 minutes

 

1、洗净镀槽,银保护剂与纯水的配比比例为14-20倍水,加热至4050度。

 

1. Clean the plating bath. The ratio of silver protector to pure water is 1:4-20 times of water. Heat to 40-50 ℃.

 

2、221L摇匀后倒出,在缓慢搅拌下,加入纯水中。221L如储存低于25℃以下,会变得粘绸或部分固化,须把容器放在40-50°C温水内,使之受热变成透明液体,方便倒出。

 

2. Shake 221l, pour it out, stir it slowly, and add pure water. If 221l is stored below 25 ℃, it will become sticky silk or partially solidified. The container must be placed in 40 - 50 ° C warm water, so that it becomes transparent liquid when heated, which is convenient to pour out.

 

3、加纯水至所须体积,调整温度,搅拌均匀,即可使用。

 

3. Add pure water to the required volume, adjust the temperature, mix evenly, and then use.

二、操作方法:

 

II. Operation method:

 

1、入槽浸泡的零件,可以是带水或烘干的,但必须是干净或已活化过。

 

1. The parts soaked in the tank can be with water or dried, but they must be clean or activated.

 

2、零件浸泡后,宜在微温纯水(35-42℃)或除油剂中清洗0.5-1.0分钟(亮面银如起雾,可以在无水乙醇中涮洗变亮且不影响保护效果)

 

2. After the parts are soaked, they should be cleaned in pure water (35-42 ℃) or degreaser for 0.5-1.0 minutes (if the bright silver is foggy, it can be rinsed in anhydrous ethanol and become bright without affecting the protection effect).

 

3、然后在纯水清洗1-3分钟。清洗干净后烘干。

 

3. Then wash in pure water for 1-3 minutes. Clean and dry.

 

 

 

三、维护:

 

III. maintenance:

 

工作液停用时间较长,或冷却一段时间后,保护剂会分层,不会影响使用效果。可稍加温至40℃即回复正常。经常加纯水,补充溶液蒸发损失,其浓度可用分析方法控制,亦可按经验维护添加,大约100平方米补充2221L银保护剂即可。亦可以根据产量,每天在槽液中补加1-2%221L原液,当槽液在正常工作温度也变浑浊老化,抗氧化效果下降,建议更换槽液,重新开槽。

 

When the working fluid is out of service for a long time, or after cooling for a period of time, the protective agent will be layered, which will not affect the use effect. It can be slightly heated to 40 ℃ to return to normal. Add pure water frequently to make up the evaporation loss of solution. Its concentration can be controlled by analytical method. It can also be added according to experience maintenance. About 100 square meters, add 2 liters of 221l silver protector. According to the output, add 1-2% 221l of stock solution to the tank solution every day. When the tank solution becomes turbid and aged at normal working temperature, the anti-oxidation effect decreases. It is recommended to replace the tank solution and re open the tank.

 

4、工作溶液浓度分析方法:

 

4. Working solution concentration analysis method:

 

A、用移液管取20m/L工作液,注入250mL三角瓶中。

 

A. use a pipette to take 20 m / L working solution and inject it into a 250 ml triangular flask.

 

B、在三角瓶中加入0.1N碘液20mL

 

B. add 20ml of 0.1N iodine solution into the triangular flask

 

C、搅拌10分钟。

 

C. stir for 10 minutes.

 

D、用0.1N硫代硫酸钠滴定,至淡黄色。

 

D. titrate with 0.1N sodium thiosulfate to light yellow.

 

E、加入1mL 1%淀粉指示剂.

 

E. add 1ml 1% starch indicator.

 

F、继续用0.1N硫代硫酸钠滴定至无色为终点,

 

F. continue to titrate with 0.1N sodium thiosulfate to colorless end point, then

 

工作液浓度%=150×(20V)/7.5

 

Working solution concentration% = 150 × (20-v) / 7.5

 

可每次重复做二次分析,以确保分析结果准确。

 

The secondary analysis can be repeated every time to ensure the accuracy of the analysis results.

 

 

 

四、故障处理

 

IV. troubleshooting

 

1、有痕迹或条纹:原因一预清洗不理想,需保证所有进入溶液内的工件已彻底清洗,原因二水洗槽被污染,可以温水洗代替或增加水洗速度改善。

 

1. There are traces or stripes: for the first reason, the pre cleaning is not ideal, it is necessary to ensure that all the workpieces entering the solution have been thoroughly cleaned, and for the second reason, the water washing tank is polluted, which can be replaced by warm water washing or the speed of water washing can be improved.

 

2、工件未能通过防腐试验:可调整溶液至标准浓度,或检查温度是否正确,尤其在装饰性用途,水洗温度不得高于30℃。

 

2. The workpiece fails to pass the anti-corrosion test: adjust the solution to the standard concentration, or check whether the temperature is correct, especially for decorative purposes, the washing temperature shall not be higher than 30 .
