在生活中我们将普通铁件称之为“黑铁”，将镀锌铁板称之为“白铁”，黑白铁加工厂，就带大家了解一下白铁皮这种金属材料，本文主要介绍的是白铁，以及什么是白铁，它的优点是什么，以及它的用途。

In our daily life, we call ordinary iron parts "black iron" and galvanized iron sheet "white iron". The black-and-white iron processing plant will take you to know the metal material of white iron sheet. This paper mainly introduces white iron, what is white iron, what are its advantages, and its uses.

黑白铁加工中的白铁皮是怎样的！

What is the white iron sheet in black and white iron processing!

白铁皮在日常生活中被广泛使用。它是一种使用寿命很长的金属材料。白铁片俗称镀锌铁皮，全称应为“连续镀锌薄板”。有平板和波形两种。主要成分为延展性较强的铁和锌的合金。具体地说，钢板酸洗后，经热镀锌处理后，在钢板表面涂上厚度大于0.02mm的锌保护层。

Tin is widely used in daily life. It is a metal material with long service life. White iron sheet commonly known as galvanized sheet, the full name should be "continuous galvanized sheet". There are two types: flat plate and waveform. It is mainly composed of iron and zinc alloys with strong ductility. Specifically, after pickling and hot galvanizing, the steel plate is coated with a zinc protective layer with a thickness of more than 0.02mm.

使用白铁皮的优点：由于锌的电极电位低于铁，其化学性质相对活跃，不易生锈和耐腐蚀。该层氧化锌膜可以在空气中快速形成一层氧化锌膜。该层氧化锌膜非常致密，保护锌和钢板免受腐蚀。即使镀锌层被擦除，由于锌的氧化而对铁进行保护，大大提高了钢板的耐腐蚀性。容器采用镀锌板制成后，无需进行表面防腐处理。但锌易溶于酸或碱，易与硫化物发生反应，不适用于酸、碱或硫化物的包装。

Advantages of using white iron sheet: because the electrode potential of zinc is lower than that of iron, its chemical properties are relatively active, not easy to rust and corrosion resistance. The ZnO film can quickly form a ZnO film in air. The zinc oxide film is very dense, which can protect zinc and steel plate from corrosion. Even if the zinc coating is removed, the iron is protected by the oxidation of zinc, which greatly improves the corrosion resistance of the steel plate. After the container is made of galvanized sheet, there is no need for surface anti-corrosion treatment. However, zinc is easy to dissolve in acid or alkali and react with sulfide, so it is not suitable for packaging of acid, alkali or sulfide.

白铁皮是一种广泛应用于工业和制造业的铁皮卷，在人们的日常生活中常被称为白铁皮。这种容器强度高，密封性能好，广泛用于制造金属包装容器。特别是制桶是一种理想的材料，所以它被用来制造各种包装工业产品的钢制桶。

Sheet iron is a kind of sheet iron coil widely used in industry and manufacturing, which is often called sheet iron in people's daily life. This kind of container has high strength and good sealing performance, and is widely used in manufacturing metal packaging containers. In particular, barrel making is an ideal material, so it is used to make all kinds of steel barrels for packaging industrial products.
