Tin is more durable than tinplate, which will rot if it breaks a little. However, even if a large piece of tin is broken, it is not easy to rust. This is because the chemical properties of zinc are more active than iron. When external air and water "attack" tin, zinc and oxygen are the first, and protect the safety of iron. However, tin is more expensive than tin.
In addition to tin chips, zinc is also used to make dry cell enclosures. But zinc in dry cells is cleaner. In addition, zinc and copper become copper zinc alloy - brass.
The compound used to process tin is zinc oxide, commonly known as "zinc white", which is a famous white pigment used to make white coatings. Zinc oxide is white at room temperature, turning yellow when heated and white when cooled. Now, people use this function to make "color change thermometer", and use the change of color to measure the temperature.
From the current business field or production situation, the demand for iron processing products is still relatively large. Mainly because this product has a very wide range of applications. For example, in the canteen of some enterprises or units, many products are processed with tin.
At present, people use a lot of barrel products, pipe sealing products also use this tin processing technology, which can ensure the use value of products, a certain life, but also ensure the overall appearance advantage, which is also an important reason for the development of tin processing industry.
With the development of science and technology, people's needs are also developing towards a higher level. In order to meet the needs of consumers, Shandong ventilation industry has to speed up the pace of development and improve the competitiveness of enterprises.
