Alkaline galvanizing and acid galvanizing each have their advantages and disadvantages, and the choice of which is better depends on the specific application requirements and environmental conditions.
Advantages of alkaline galvanizing
Higher corrosion resistance: Alkaline galvanized layers have better corrosion resistance, especially in wet environments.
Good bonding: Alkaline cyanide-free galvanizing additives provide a strong bonding of the coating with low brittleness, making it suitable for applications where deep plating capability is required.
Good environmental performance: Cyanide-free alkaline galvanizing additives have less impact on the environment and human health, and the plating solution is stable and easy to maintain.
Advantages of acid galvanizing
Fast polishing speed: Acid galvanizing process is simple, fast polishing speed, suitable for occasions that require fast processing.
Small surface dimensional error: Acid galvanizing can provide a thinner zinc layer and small surface dimensional error, which is suitable for products with high precision requirements.
Wide range of application: Acid galvanizing can be carried out at lower temperatures, suitable for mixed metals and has a higher tolerance for impurities.
Application Scenarios
Alkaline galvanizing: Suitable for environments requiring high corrosion resistance, such as chemical and marine engineering.
Acid galvanizing: Suitable for situations requiring quick processing and high precision requirements, such as electronics and precision instrument manufacturing.
Cost and environmental impact
Alkaline galvanizing: Although the cost is higher, it has good environmental performance and is suitable for occasions with strict environmental requirements.
Acid galvanizing: the cost is lower, but it is more polluting to the environment and requires strict operation and management.
Through the above comparison, users can choose the appropriate galvanizing process according to specific needs.
