Galvanized elbow is a type of elbow that involves coating the surface of the elbow with a layer of zinc material to improve its corrosion resistance. Galvanized elbows are divided into two types: hot-dip galvanized and electroplated. The hot-dip galvanized layer is thick, the cost of electroplated is low, and the surface is not very smooth. Galvanized bent pipes are divided into cold plated pipes and hot-dip plated pipes. The former has been banned, while the latter has been temporarily promoted by the state for use.
1. Optimization of Sulfate Zinc Plating
The biggest advantage of sulfate galvanized elbows is that the current efficiency can reach up to 100% and the deposition rate is fast, which is incomparable to other galvanizing processes. Due to insufficient crystallinity and poor dispersion and deep plating ability of the coating, it is only suitable for electroplating pipes and wires with simple geometric shapes.
2. Conversion of Sulfate Zinc Plating
Sulfate galvanized elbow iron alloy only retains the main salt zinc sulfate of sulfate galvanized, while other components such as aluminum sulfate and alum (potassium aluminum sulfate) can be added to the plating solution during treatment to form insoluble hydroxide precipitates for removal; For organic additives, add powdered activated carbon for adsorption and removal.
3. Fast sedimentation rate and excellent protective performance
The current efficiency of the sulfate electroplating galvanized elbow alloy process is as high as 100%, and the deposition rate is unparalleled by any galvanizing process. The operating speed of the fine tube is 8-12 m/min, and the average coating thickness is 2 m/min, which is difficult to achieve by continuous galvanizing.
4. Unique clean production
The galvanized elbow adopts the sulfate electroplated galvanized iron alloy process, which means that the production line slot and slot are perforated and directly connected without any solution leakage or overflow.
5. The particularity of electroplating equipment
The electroplating of galvanized elbows, like the electroplating of wire, belongs to continuous electroplating, but the equipment used for electroplating is different. A plating groove designed for iron wire with its slender strip characteristics, the groove body is long and wide but shallow. During electroplating, the iron wire penetrates through the hole and unfolds in a straight line on the liquid surface, maintaining a distance between them.
