The difference between slaughter chain and ordinary chain

First, ordinary chain: chromium is a silver self-colored metal, it is very stable in the atmosphere, even in alkali, nitric acid, sulfide, carbonate solution can also maintain a stable state. Chromium has a hard texture, strong wear resistance, and can maintain its luster for a long time. The disadvantage of chromium plating is that it does not protect the base metal from rusting. Therefore, before it is also plated with copper or copper-tin alloy coating that can be well combined with the base metal. In general, the chrome-plated chain has the characteristics of a slightly higher cost, and most light vehicles use it, which is generally not recommended.

Second, slaughtering chain: the appearance of galvanized chain is green. That is the result of passivation and then bleaching of zinc coating. The zinc coating hardly changes in dry air. In humid air, in water containing carbon dioxide and oxygen, its surface will form a film composed mainly of basic zinc carbonate. This film has an anticorrosive effect. It can prevent the metal from continuing to corrode. We see that some galvanized chains are quickly converted from white to brown after use, but there is no greater change after this, and the reason is that.         

  Compared with ordinary iron chains, galvanized chains undergo special galvanized treatment in production and processing, and show more excellent characteristics in use, so that it has different degrees of improvement from the service life of the product or the actual use. The process of galvanizing is relatively simple, the cost is relatively low, so the ordinary type and heavy duty bicycles are used with it.
