Technological Features of Galvanized Pipe

Sulfate Zinc optimization
Sulfate Zinc biggest advantage is up to 100% current efficiency, deposition rate, which is incomparable to other galvanizing process. Because crystalline coating is not detailed enough, dispersing ability and throwing ability is poor, and therefore only suitable for simple geometries such as pipe and wire plating. Sulfate galvanized iron alloy craft traditional sulfate galvanizing process optimization, leaving only the main zinc sulfate salt, and the remaining components are discarded. In the process of forming a new formula also add the right amount of iron salt, so that the original single metal plating to form a zinc-iron alloy coating. Restructuring process, not only carry high current efficiency of the original process, the advantages of fast deposition rate, but also the dispersion ability and throwing ability has been greatly improved in the past can not be plated complex parts, now simple and complex parts can be plated, and protective properties increased by 3 to 5 times higher than a single metal. Practice has proved that for wire, pipe continuous plating, coating the grain is more refined than the original, more bright, fast deposition rate. Within 2 ~ 3 min plating thickness to meet the requirements.

Deposition rate, excellent protection performance
Sulfate galvanized iron alloy craft up to 100% current efficiency, fast deposition rate is unmatched in any galvanizing process, runs fine tube 8 ~ 12 m / min, the average thickness of the coating 2m / min, which is a continuous galvanizing difficult achieved. Bright coating meticulous eye.

Galvanized sulfate conversion
Sulfate galvanized iron alloy to retain only the main salt sulfate galvanized zinc sulfate, and the remaining components such as aluminum sulfate, alum (potassium aluminum sulfate), etc. can be processed at the time of the bath, so that by adding sodium hydroxide to form insoluble hydroxide precipitate removal; organic additive, then add powdered activated carbon adsorption removed. Tests showed that aluminum sulfate and potassium aluminum sulfate is difficult to completely remove the one-time, the coating brightness influential, but not serious, may consume comes out, then the brightness of the coating solution can be restored through treatment, according to the new technology require additional ingredients, to complete the conversion.
