Zinc - metal applications
Ductile and at the same time unstable non-ferrous metal is widely used in the modern industrial sector. It has proven itself especially well as a durable coating for protecting sheet metal. High-quality zinc ingots https://zink.su/, obtained from natural raw materials, does not require additional heat treatment. It can be used for its intended purpose.
Important chemical properties of the metal
The alloy, upon contact with oxygen, is almost instantly covered with a thin, invisible oxide film. Due to its natural strength, further oxidation of the non-ferrous metal does not occur. It perfectly protects the steel base from temperature changes and high humidity. But zinc itself also has important chemical properties used in industry:
- It can react chemically with sulfuric acid.
- It has a tendency to independently restore its surface.
- Capable of releasing oxides and chlorines during overheating.
- Widely used in the chemical industry as a catalyst.
- In a salt solution, it displaces relatively passive metals.
During everyday use as a protective coating, zinc is not at all afraid of temperature changes, including negative ones. Can naturally adhere to steel alloys for a long time. Does not require additional layers of protection in the form of paints and varnishes.
Use of metal in practice
Approximately 60% of all zinc produced in the world is used to create a protective coating for sheet steel and other metal structures. Special baths of molten metal are used as a base into which metal products are immersed to form a protective layer. But, non-ferrous metal can also be used in other areas:
- as a decorative coating on individual parts;
- to create strong and durable printing forms;
- li>drainage pipes for removing waste water;
- used in small quantities in cosmetology and pharmaceuticals.
Galvanization is carried out using hot and cold methods. Each has its own individual merits. But, subject to technology, both methods guarantee a durable and reliable protective coating.
