The common uses of zinc that you didn't know about

With many common uses of zinc, you can be sure that you'll never run out of ways to use this indispensable mineral. When zinc was first discovered, people thought that it had no practical value or use. However, they were wrong, and today there are many applications of zinc across various industries and fields of science. This article lists the top uses of zinc that you didn't know about.

1) Corrosion protection

Zinc is used as a galvanizing agent to protect iron or steel structures and machinery from corrosion. This can be seen in many examples, such as bridges, road signs, railings, water towers, and automobiles. Galvanized steel is essentially zinc-coated steel that prevents rusting, protecting the integrity and durability of the structure. The zinc coating is thick enough to block oxygen corrosion but thin enough to allow light to pass through.

2) Paint pigments

Zinc oxide is used as a pigment to color paint. It is the most widely used pigment for most paints and paints that are used in the interior and exterior of buildings, industrial facilities, containers, and metal products. Colors such as orange and red are commonly found in paints, whereas whites, black, browns, and greys are almost never found.

3) Zinc oxide is used as a component of pesticides

Zinc carbide is the active ingredient in many pesticides, such as those made by Bayer. This combination prevents plants from germinating and killing them by causing harm to the root system. Some agents use zinc sulfate or zinc gluconate, while others combine them with a binder such as clay.

4) Zinc is used as a stabilizer

Zinc is added to paints and coatings as an anti-caking agent. When oils and resins such as linseed oil and alkyd are used in paints, they will separate when they dry. Zinc is added to prevent this separation from happening since it's naturally found in resins and linseed oil.

5) Water treatment

One of the common uses of zinc is to purify water because it's cost-effective and effective at removing germs, odors, suspended solids, color, and chemical compounds. It has been used for over a hundred years for water purification in both municipal and industrial settings.

6) Flavorings

Zinc chloride is used as a flavor enhancer in the food industry. Zinc salts are mixed with other chemicals that can increase the loss of weight in dried foods and wine. When foods are added to wines, they help to stabilize the red color of the drinks by adding flavors to them. Most commonly, these salts are used as an additive in spices, snacks, and beverages like beer.

7) Blood donor plasma donation

Plasma is a portion of blood that is dissolved in a liquid solution and then separated into components using specialized equipment. Blood is the protein, red blood cells, and white blood cells that carry oxygen. When there isn't enough plasma, it can be donated. The plasma is then used for transfusions in people with certain health conditions, such as cancer patients, patients having surgery, and patients receiving chemotherapy.

8) Zinc catalyst

Acting as a catalyst that speeds up chemical reactions is one of the common uses of zinc. This makes it ideal for various types of reactions, such as converting ammonia into ammonium sulfate, converting sulfur dioxide into sulfur trioxide, and converting sulfur sulfide to sulfate salts or zinc sulfide to elemental zinc using other chemicals.

9) Zinc white is used in advertisements

Zinc white paint is commonly used to create a matte or glossy finish on walls, ceilings, and other surfaces. It also makes materials like paper, plastics, and metals look newer. Another benefit of using white zinc paint is that it can be easily repainted without damaging the surface.

10) When organic acids attack metals, zinc reacts with the acid via donation

Zinc salts are added to sulfuric acid to form zinc sulfide. This acts as a scavenger in reactions where sulfuric acid attacks glass, plastics, and certain metals such as steel, cast iron, and aluminum oxide under certain conditions that preserve the quality of the metal substrate.

Conclusion

Zinc is an important element that has played a significant part in the history of medicine, the development of different industries, applications in science and technology, and the advancement of mankind in general. Although you don't use it every day, zinc will always be present to help you when in need.
