一.Product description : LT-501 for pure gold electroplating bath low acid, extremely smooth uniform coating color 24K gold, easily control the economy.
二. The operating conditions :
The scope of the standard
The salt (68%) 1.5 g / L 1 - 12g / L
The proportion of 11Be ° above 10-16Be °
PH 5.8 5-7
50 ° C temperature 45-55 ° C
5ASF cathode current density 4-20ASF
Μ filtration five consecutive MP.PP/WG.1/2003/4 cotton filter core
三.Three open cylinder : LT-501 for 180 tanks opened grams / liter, FM-501 supplements 2.2 ml / per gram of gold salt, the salt of 1.5 grams / liter.
四. Bath maintenance :
1. To maintain the stability of the content, each of the accession of 10 grams of salt to make up for an additional 20 ml of FM-501 supplements.
2. The use of LT-501 conductive salt maintain stability Baume degrees, about 15 grams / liter conductive salt bath can increase the proportion of 0.01.
3. Every 4.5 grams / liter LT-501-Bath Salts can reduce PH0.1, 1.5 grams / or potassium hydroxide reagents can be increased PH0.1.
4. 400 amperes per minute to add 10 grams of gold salt, strictly control the water loss, consumption, consumption per 100 grams of salt while the consumption of 200 ml of LT-501 supplements and 2.5 kilograms of LT-501 conductive salt. |
