　　过去，有很多工匠从事白铁加工，借助他们灵巧的双手，用水桶、水瓶等各种生活方式给人们带来方便。其实这种白铁是镀锌铁加工的，在今天的社会中，以前的桶、壶已经逐渐被淘汰，而现在的黑铁和白铁加工已经没有被人们所遗忘，而是在其他行业中发挥了更大的价值。目前黑白铁加工主要集中在空调通风管道、室内通风、新风管道、各种排烟、排气管的生产安装工程。

　　In the past, many Chinese craftsmen engaged in white iron processing, with the help of their dexterous hands, buckets, water bottles and other lifestyles to bring convenience to people. In fact, this kind of white iron is processed by galvanized iron. In today's society, the former barrels and pots have been gradually eliminated, but now the processing of black iron and white iron has not been forgotten by people, but has played a greater role in other industries. At present, the processing of black and white iron mainly focuses on the production and installation of air conditioning and ventilation ducts, indoor ventilation, fresh air ducts, various smoke exhaust and exhaust pipes.

　　镀锌铁在黑白铁加工中使用的不仅仅是一层简单的锌在金属表面，其中包含了许多化学原理。制造白铁的过程很简单。把铁浸入锌溶液中。由于锌的反应性比铁强，所以在铁与空气和空气中的水发生反应之前，锌就形成了一层稳定的保护膜。化学上的解释是，锌和铁形成一个原电池，而锌的反应性更强，并作为负极氧化，因此铁受到保护。这种保护膜不仅能保护里面的活性锌，还能保护里面的铁。因此，从长远来看，铁产品的使用寿命更长，成本更低。而且生产工艺简单，有越来越多的单位或企业选用白口铸铁。

　　Galvanized iron in black and white iron processing is not only a simple layer of zinc on the metal surface, which contains many chemical principles. The process of making white iron is very simple. Iron is immersed in zinc solution. Because zinc is more reactive than iron, zinc forms a stable protective film before iron reacts with air and water in the air. The chemical explanation is that zinc and iron form a primary cell, while zinc is more reactive and acts as a negative electrode for oxidation, so iron is protected. This protective film not only protects the active zinc, but also protects the iron inside. Therefore, in the long run, iron products have longer service life and lower cost. And the production process is simple, more and more units or enterprises choose white cast iron.

　　目前，黑、白铸铁通风管道在建筑中得到了广泛的应用。由它们制成的各种管道在通风方面都能起到一定的作用。一般来说，在建筑物的地下室，由于通风不良和阳光直射，容易发生一些阴暗潮湿的现象，容易影响建筑物的地基。因此，在施工中需要进行通风设计。

　　At present, black and white cast iron ventilation pipes have been widely used in construction. All kinds of pipes made of them can play a certain role in ventilation. Generally speaking, in the basement of buildings, due to poor ventilation and direct sunlight, it is easy to occur some dark and humid phenomena, which easily affect the foundation of buildings. Therefore, ventilation design is needed in construction.
