First of all, the main components are different.
1, electroplating 14K gold ornaments: the main component of electroplating 14K gold ornaments is silver or other gold.
2. 14K pure gold jewelry: 14K pure gold jewelry is mainly composed of gold.
Second, the use is different.
1, electroplating 14K gold ornaments: electroplating 14K gold ornaments are mostly used for larger ornaments, such as gold-plated necklaces and bracelets.
2. 14K pure gold ornaments: 14K pure gold ornaments are mostly used for smaller ornaments, such as gold coins and gold rings.
Third, the corrosion resistance is different
1, electroplating 14K gold jewelry: electroplating 14K gold jewelry has poor corrosion resistance, and it will fade after being worn normally for one or two years.
2. 14K pure gold jewelry: 14K pure gold jewelry has good corrosion resistance and will not fade after normal wear for many years.
Extended data
Electroplating requires a low-voltage and high-current electroplating bath power supply and an electrolytic device consisting of electroplating solution, plated parts (cathode) and anode. The composition of electroplating solution varies with the coating, but they all contain main salts that provide metal ions.
Complexing agent capable of complexing metal ions in the main salt to form a complex, buffer for stabilizing the pH value of the solution, anode activator and special additives (such as brightener, grain refiner, leveler, wetting agent, stress eliminator and fog suppressant, etc.). ).
Electroplating is a process in which metal ions in plating solution are reduced to metal atoms by electrode reaction under the action of external electric field, and metal deposition is carried out on the cathode. Therefore, this is a metal electrodeposition process including liquid phase mass transfer, electrochemical reaction and electrocrystallization.
