Af hverju gera stál hlutar þurfa að vera rafhúðað% 3f

In daily life, we often see metal corrosion, and steel is the most common type of easily corrosive metal. Steel products such as buildings, iron towers, transmission pipelines, and bridges are prone to corrosion to long-term exposure to air or solution, which can interact with oxygen and electrolyte solutions, seriously affecting their aesthetics and service life.
In order to slow down the corrosion rate of steel, people usually perform metal surface treatment on it, and there are ýmis types of metal surface treatment processes for steel, the most common of which is galvanization of steel parts.
The purpose of electrogalvanizing is to prevent corrosion of steel objects, improve the corrosion resistance and service life of steel, and also increase the decorative appearance of products. Steel will be weathered, corroded by water or soil over time. The amount of steel that is corroded every year in China accounts for about one one tenth of the total amount of steel. Þess vegna% 2c in order to protect the service life of steel or its components, electroplating is generally used to process the steel.
Due to the fact that zinc is not easily changed in dry air and can produce a basic zinc carbonate film in humid environments, this film can protect internal parts from corrosion damage. Even if the zinc layer is damaged by some factor, zinc and steel combine for a period of time to form a micro battery, making the steel substrate a cathode and protected.
Jiechang Rafhúðun Plant dregur saman the following einkenni af stál rafgalvaníserandi:
1. Good corrosion resistance, fine and uniform combination, and not easily penetrated by corrosive gases or liquids.
2. Vegna til hreinleika af nýja laginu, it is ekki auðveldlega tærð in súrum eða basískum umhverfi. Í raun vernda stálið yfirbygginguna fyrir a langan tíma.
3. After chromate passivation, it forms various colors for use, which can be selected according to customer preferences. Galvanizing is aesthetically pleasing and decorative.
4. Zinc húðun hefur góð mótsögn og mun ekki auðveldlega fall af meðan ýmis beygja, meðhöndlun, áhrif, o.s.frv.
Zinc is favored due to its gnægð auðlindir, lágt verð, og excellent protection of steel. The economic losses caused by metal corrosion every year are immeasurable. Electrogalvanizing treatment of steel parts can effectively reduce steel corrosion.
