在玻璃表面镀银一般都要在较高的温度下进行,而且耗银量较高。以一般热水瓶厂在玻璃瓶胆上镀银为例,通常控制温度均高达90℃以上,每万只5磅瓶耗银量为3～4公斤。为了克服以上缺点,我们经多次实验,摸索出了可在常温下低银耗镀银的一种新方法。以五磅保温瓶胆为例,先用碱、自来水、蒸馏水洗,再用万分之一的氯化亚锡溶液处理待镀瓶胆内壁。倒掉处理过的氯化亚锡溶液(此溶液可反复使用),即可加入化学镀液并缓慢转动瓶胆,一般4～5分钟左右即可镀好一个瓶胆。具体镀液配方为:2％ HgNO_3 13ml,6N NaOH 2ml,28％NH_3·H_2O 3ml,3％ C_6H_(12)O_6 10ml(加水到40ml),10ppm NH_2-NH_2 0.5ml,
Silver on the glass surface generally have to be carried out at higher temperatures, but also consume a higher amount of silver. The general thermos factory glass in the glass on the gallbladder, for example, usually control the temperature is as high as 90 ℃, 5 pounds per million bottles of silver consumption of 3 to 4 kg. In order to overcome the above shortcomings, we have tried many times to find a new method that can reduce the silver consumption at low temperature at normal temperature. To five pounds of thermos flask gallbladder, for example, first with alkali, tap water, distilled water, and then one ten thousandth of the stannous chloride solution to be plated bile wall. Pour off the treated stannous chloride solution (this solution can be used repeatedly), you can join the electroless plating solution and slowly turn the bottle, usually about 4 to 5 minutes to plate a bottle of gall. The specific plating solution is as follows: 10 ml of 2% HgNO_3, 2 ml of 6N NaOH, 3 ml of 28% NH_3 · H_2O and 0.5 ml of 3% C_6H_ (12) O_6,
