Aerosol Products

It is a substance enclosed under pressure and released as a fine spray by means of a propellant gas.

Aerosols are used in cosmetics such as hairspray, deodorant sprays, foaming agents, sprays and sunscreens etc. In addition, they are used in health care as disinfectants, inhalers, anesthetic preparations, etc. Household preparations in aerosol cans include air fresheners, cleaning agents, car cosmetics, paints and varnishes, etc. They are also very popular in Indistrial application for maintenance related products.

Here are some basic advantages of aerosol spray :
1.Convenient
2.Easy to use
3.Controlled application
4.Compact & portable
5.Long lasting & uniform spray

The goal of aerosol valve is to regulate the entrance/exit of a fluid to or from some source. A specific objective of the aerosol valve is to atomize the contents of the source so that it exits as a fine spray.

There are two types of propellants:
1.A compressed gas (eg. nitrogen or carbon dioxide)
2.A liquid (liquefied gas) (eg. butane,isobutane,propane)

The actuator controls the fineness of the product spray, as well as the amount of product that is dispensed. When you press down on it, the valve is opened. When the valve opens, the pressure is released from the top of the aerosol can and the pressurized propellant tries to escape from the can

Aerosols can be used for for diverse applications like electronic or electrical contact cleaner, dielectric grease coating in aerosol sprays, food grade lubricants in aerosol sprays,zinc rich paint in aerosol sprays popularly known as Galva Coatings, anti-friction coatings, Anti seize in aerosol sprays, moly coating, insulating varnishes to protect electrical & electronic components from unwanted environmental effects,leaks detector sprays to detect unwanted surface defects caused during manufacturing, cleaners etc.

The pressure inside an aerosol is bigger than atmospheric pressure. It ranges from 2 to 8 times the pressure of the atmosphere. This means that the can has to be very strong to withstand the difference in pressure between the inside and the outside.

1.Do not spray or discard aerosol cans on or near a fire. Even if the can is empty, it can still explode or cause injury.
2.Never pierce a hole into aerosols since the can might still be pressurized.
3.Keep aerosols in a safe, cool place away from sunlight. Indirect heat can cause the can to explode.
