Tinplate, also known as tinplate, is a tin plated steel substrate. The thin steel plate substrate is made of low carbon steel and its thickness is generally 0.1-0.4 mm.
Tin-plated steel can be divided into two types depending on the tin plating process, namely hot-dip tinplate and tin plating.
In an acidic environment, the tin protective layer of tinplate is in direct contact with the outside world, and since tin is eroded very slowly, it plays a role in protecting the substrate. If there are defects such as pinholes and cracks in the tin protective layer, part of the substrate will be exposed, causing the substrate to be corroded quickly.
Tinplate is a tin plate coated with a layer of tin on the surface. It is not easy to rust and is also called tinplate. Tinplate was first produced in Bohemia (now in the Czech Republic and Slovakia). The area has been rich in metal since ancient times, advanced technology, and know how to use water power in machine manufacturing, began production of tinplate since the 14th century. For a long period of time, it has been the main producer of tinplate in the world. At that time, tinplate was mainly used to make tableware and drinking equipment.
In the 17th century, Britain, France, and Sweden had all hoped to establish their own tinplate industry. However, due to the large amount of funds required, it has not yet been developed. It was not until 1811 that Brian Tinkin and John Hall opened tin canned foods, but tinplate manufacturing began to develop on a large scale. Today, the world produces about 250,000 tons of tin each year, and more than one-third of it is used to make tinplate, most of which are used in the canned food industry.
