Aerosol products are very common in my daily life, from hair spray to personal care to lubricants and car care products. They are involved in many industries. Every time you use an aerosol product, you know How does an aerosol can work? Of course, what happens inside the can is something we can’t see, but in the world we can’t see, it’s doing a complicated job. In order to understand the aerosol How it works, we need to break it down into its components and explore each component in detail.
First of all, an aerosol can consists of three main parts: the container, the valve system, and the contents.
Aerosol can manufacturers typically use aluminum or tinplate, chosen for their durability and ability to withstand high pressures. A valve system located on the top of the tank controls the release of the contents. Finally, its contents can vary depending on the product and can be liquid, gas, or a mixture of both.
When you press the nozzle of an aerosol can, you initiate a series of events that cause the aerosol to be released. The valve system opens, allowing the pressurized aerosol to escape. When aerosols are released, they pass through narrow openings to form a fine mist or spray. Typically, aerosol contents are stored at 2-8 times normal atmospheric pressure. That’s why the aerosol shoots out instantly when you press the button. The valve opens via a spring mechanism and the gas is then compressed, further exerting pressure on the product. The product then goes into the dip tube and the product comes out through the dip tube. Once the knob is released, the valve will close. Sprays are available in mist, foam and wet forms, depending on the type of valve and product concentrate.
Some everyday examples of aerosols include deodorant, mosquito repellent, Relispray, vesaire.
