Galvanizing is a method of applying a layer of zinc to a metal surface to create a protective layer against oxidation, limit rust and increase product life.<\/p>\n
Thanks to this coating, steel, iron or alloy materials can be more resistant to moisture, salt, chemicals and the effects of the industrial environment. Not only improving durability, galvanizing also helps increase the aesthetics of the product with a brighter, more uniform and professional surface.<\/p>\n
Currently, galvanizing technology is widely applied in:<\/p>\n
- \n
- Steel and galvanized steel industry<\/li>\n
- Mechanical Components<\/li>\n
- Industrial Equipment<\/li>\n
- Construction Structure<\/li>\n
- Cars and motorcycles<\/li>\n
- Electrical and Household Appliances<\/li>\n<\/ul>\n

<\/p>\nZinc plating chemicals play a crucial role in improving the quality of the plating layer<\/em><\/span><\/p>\n
Classification of common galvanizing chemicals today<\/strong><\/h3>\n
Depending on the technology and technical requirements, galvanized chemicals are now divided into various groups. Each type possesses its own advantages in terms of durability, corrosion resistance and environmental friendliness.<\/p>\n
Acidic Galvanizing Chemicals<\/strong><\/p>\n
This is a line of chemicals that are quite commonly used thanks to its ability to create a coating with good adhesion and uniform distribution on metal surfaces.<\/p>\n
The advantages of the acid system include:<\/p>\n
- \n
- Easy to apply<\/li>\n
- Reasonable cost<\/li>\n
- High efficiency with complex parts<\/li>\n
- Limit chemical evaporation during operation<\/li>\n<\/ul>\n
Thanks to its ability to create an evenly thick zinc layer, acid systems are often used in large-scale industrial plating lines.<\/p>\n
Non-Cyanide Alkaline Galvanizing Chemicals<\/strong><\/p>\n
Modern manufacturing trends are increasingly prioritizing safe and environmentally friendly solutions. Therefore, cyanide-free alkaline galvanized chemicals are being widely used in many countries such as Japan, South Korea and Taiwan.<\/p>\n
This line of chemicals has many advantages:<\/p>\n
- \n
- Reduced Toxicity to Operators<\/li>\n
- Limiting environmental pollution<\/li>\n
- Increase the shine of plating<\/li>\n
- Easy to carry out the passivation process<\/li>\n<\/ul>\n
This is considered a suitable solution for businesses that are moving towards green production standards.<\/p>\n
Cr\u00b3\u207a Passive Galvanizing Chemicals<\/strong> \u2013 <\/strong>A New Technology Trend<\/strong><\/p>\n
In recent years, Cr\u00b3\u207a passivation technology has become a prominent trend in the metal surface treatment industry.<\/p>\n
Unlike traditional Cr6+-containing technologies, Cr\u00b3\u207a chemicals \u00a0arebetter for the environment but still ensure:<\/p>\n
- \n
- High corrosion resistance<\/li>\n
- Outstanding coating durability<\/li>\n
- Good aesthetics<\/li>\n
- Meets stringent international standards such as RoHS and REACH<\/li>\n<\/ul>\n
In particular, this technology is suitable for mechanical products, machines or materials that are frequently subjected to friction and high temperatures.<\/p>\n
Common problems with galvanization<\/strong><\/h3>\n
Although technology is increasingly modern, many businesses still encounter many errors in the plating process if the chemicals are not of good quality or the treatment process is not optimal.<\/p>\n
The plating is darkened, brittle or flaky<\/strong><\/p>\n
This is a fairly common error in acid plating systems when the solution is unbalanced or the gloss content is not suitable. The coating is then brittle, reduces adhesion and deteriorates quickly.<\/p>\n
The plated surface is pitted, rough or prickly<\/strong><\/p>\n
The cause usually comes from:<\/p>\n
- \n
- The solution is contaminated with impurities<\/li>\n
- Unstable pH<\/li>\n
- Poor filters<\/li>\n
- The plating current is too high<\/li>\n<\/ul>\n
These errors not only affect aesthetics, but also reduce the corrosion resistance of the coating.<\/p>\n
Burnt or spotted plating<\/strong><\/p>\n
When the metal concentration is low, the temperature is inappropriate, or the current exceeds the allowable level, the plating may appear surface burning or the formation of uneven color spots.<\/p>\n
Poor adhesion and blistered plating<\/strong><\/p>\n
This is a sign that the metal surface has not been completely cleaned before plating or the chemical is contaminated with organic impurities.<\/p>\n
According to technical experts, the surface pretreatment stage can determine more than 70% of the quality of the final coating.<\/p>\n
