Electroplating solution temperature

When other conditions (referring to the voltage being constant, due to the accelerated ion diffusion rate, the current will increase) remain unchanged, increasing the temperature o

cathode current density

Any plating solution has a current density range for obtaining a good coating. The minimum current density for obtaining a good coating is called the lower limit of current density

Elements of electroplating

1. Cathode: The plated object refers to various connector terminals. 2. Anode: If it is a soluble anode, it is the desired metal plating. If it is an insoluble anode, most of it is

Working principle of electroplating

Electroplating requires a low voltage and high current power supply to the electroplating tank, as well as an electrolysis device composed of electroplating solution, parts to be p

What is electroplating

Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is the process of using electrolys

Research on zincate zinc plating and development and application of additives

In the electroplating industry, galvanizing accounts for 60% of production, and in the electromechanical industry, galvanizing accounts for about 70%. Eliminating highly toxic cyan

Process conditions and bath maintenance of zincate zinc plating

This plating solution is stable, and only an appropriate amount of additives need to be added in daily life. Pay attention to adding less and more frequently each time; Regularly t

Plating solution preparation

(1) First add water to the 1/4 tank, and then pour the calculated NaOH into it to completely dissolve. (2) Mix the calculated amount of ZnO into a paste with a small amount of wate

The role of various components in the plating solution

1. Zinc oxide The content of zinc plays an important role in the performance of the plating solution and the quality of the coating. If the zinc content is too high, although the c

Characteristics of Zinc Salt Zinc Plating

Alkaline zincate zinc plating is based on zinc oxide as the main salt and sodium hydroxide (caustic soda) as the complexing agent. Its characteristics are that it has no corrosiven

What is zincate zinc plating

Zinc salt zinc plating is the process of using ZnO and NaOH solution, adding appropriate zinc plating additives And plating a layer of metal zinc on the surface of a metal or other

How to obtain a bright and uniform coating

In the pyrophosphate copper plating process, in order to obtain a bright and uniform coating, in addition to maintaining the process parameters and plating solution, it can also be
