The aerosol-can uses compressed gas as a propellant.
Since the product is liquid at room temperature, it is simply poured in before the can is sealed. The propellant, on the other hand, must be pumped in under high pressure after the can is sealed. When the propellent is kept under high enough pressure, it doesn't have any room to expand into a gas. It stays in liquid form.
When the button is pressed the pressurized gas pushes the liquid product, as well as some of the liquid propellant, up the tube to the nozzle. Some cans, such as spray-paint cans, have a ball bearing inside. If you shake the can, the rattling ball bearing helps to mix up the propellant and the product, so the product is pushed out in a fine mist.
Up until the 1980s, a lot of liquefied-gas aerosol cans used chlorofluorocarbons (CFCs) as a propellant. After scientists concluded that CFCs were harmful to the ozone layer, 70 nations signed the Montreal Protocol, an agreement to phase out CFC use over the next decade. Today, almost all aerosol cans contain alternative propellants, such as liquefied petroleum gas, which do not pose as serious a threat to the environment.

∙ 10y agoAn Aerosol spray can is a type of dispensing system which creates an aerosol mist of liquids. This is used with a can that contains a liquid under pressure. Modern aerosol cans have three major parts: the can, the valve and the button. The valve is crimped to the rig of the can, and the design of this nozzle in the actuator controls the spread of the aerosol spray.

How do you recycle aerosol cans?
Yes cans are recycled.You can make a bowling game out of cans.Turn cans into a bowling pin.
What do you call to a colloidal suspension in which a gas is the suspending medium?
- solid in gas: solid aerosol - liquid in gas: liquid aerosol
Do all aerosol cans require shaking before usage?
No. Hairspray cans and such dont have to be shaken. Usually only the cans with the little ball in the can has to be shaken up.
What does fluorocarbons as propellants in aerosol cans do to ozone layer?
hurt it hurt it bad!
What gas is in aerosol cans?
The typical gas used as a propellant in aerosol solvent based paint cans is Propane, Chemical Abstract Number 74-98-6. The propellant used will depend on the contents of the can, as it must be a chemical that is compatible with the contents. Most liquids can be put into an aerosol can. The liquid is placed into the can, the liquid is diluted to make it thin enough to spray through the nozzel of the spray can and then a compressed gas propellant is added to expel the contents of the container in the form of an aerosol.
What is the value chain of Aerosol cans?
The value chain of aerosol cans is all about supply and demand. Aerosol cans are necessary for most jobs that require spray paint, or cleaning supplies. The value will depend on what product is being used in the cans.

Do aerosol cans explode on airplanes?
no but my bottom does
Are aerosol cans allowed on airplanes?
of course
Is aerosol a source of all clouds and precipitation?
All of the common clouds are a type of aerosol. Aerosol is a suspension of fine solid or liquid particles in a gas. That is where aerosol spray cans get their name. They produce an aerosol mist when their contents are released into the air. Obviously aerosol spray cans are not the source of all clouds and precipitation. They just produce a small cloud where they are used. When the material within an aerosol coalesces and becomes too heavy to stay in suspension, it precipitates out of the cloud. While most clouds, those made of solids or liquids, are aerosols, there are other types of clouds. Gas clouds are a high concentration of one type of gas within another gas or a vacuum. Some galaxies appear to be gas clouds. Plasma clouds share a similar definition. Lighting is a natural example of a plasma cloud.
Do aerosol spray cans have to be in a cabinet?
They don't have to be in a cabinet. Some people store there aerosol cans in hollowed out TV sets and some people bury them in the ground in treasure chests. I keep my aerosol spray cans in a locked box hidden in my attic, so they will never be stolen.
Who invented aerosol spray cans?
Erik Rotheim
What is the abbreviation of chlorofluorocarbons?
CFC is the abbreviation. This abbreviation is often seen on aerosol cans. Hairspray brands such as Aqua Net in the 1980s had large aerosol cans with that abbreviation on the label.
What is being done about aerosol?
Most aerosol cans now use non-CFC propellants and are generally much kinder to the environment. Therefore they are far less damaging to the ozone-layer. Unfortunately HCFC gas used as a replacement for CFC's is potent greenhouse gas.
How do you use aerosol in a sentence?
We will also ban the sale of aerosol paint cans to children under the age of 16.
What was the ingredient in aerosol cans that banned them from use?
chlorofluorocarbons (CFCs)
Who invented aerosol sprays?
Aerosol spray cans were invented by Lyle David Goodloe and W. N. Sullivan in 1941.
