Anti-oxidation measures for metal zipper

January 14, 2020

Because oxidation is a property of metal, metal zipper will also cause the chain teeth to become black due to oxidation. In fact, when used properly, the probability of zipper being oxidized will be greatly reduced. In general, the metal zipper will be anti-oxidized after plating.

Of course, this anti-oxidation treatment will have different effects due to the process and requirements of each metal zipper manufacturer. Metal zipper manufacturers who have strict requirements on product quality will perform various tests on each batch of products. The anti-oxidation test is based on a salt spray test standard with a 5% concentration of salt solution. The metal zipper is placed in a closed constant temperature of 37.5 ℃. The continuous spray test under the environment, which is qualified if the plating layer does not change for more than 48 hours, is an important test to ensure the oxidation resistance of metal zipper.

Selecting a metal zipper manufacturer with strict requirements on product quality is the basic principle to ensure that the product itself is not prone to oxidation. The metal zipper passed the test is enough to easily deal with the conditions that affect the oxidation of the metal zipper, such as leather acid, humid environment, and high temperature. If it can be used often, the problem of preventing zipper oxidation can be solved.
