Aerosolisäiliöt

Aerosolisäiliöt, commonly known as aerosol cans, are pressurized containers designed to dispense a product as a fine spray. They consist of a metal or plastic body, a valve assembly, and a propellant. The propellant, often a liquefied gas like butane or propane, is mixed with the product, such as paint, insecticide, or hairspray. When the valve is pressed, the pressure difference forces the propellant and product mixture through a narrow nozzle, creating an aerosol.

The history of aerosol technology dates back to the late 1920s when Norwegian chemist Erik Rotheim patented the first aerosol valve. The technology gained wider commercial use in the United States during World War II for dispensing insect repellent and flameless lighters. Post-war, aerosol cans became popular for a wide range of consumer products.

Modern aerosol cans are typically made of aluminum or steel and are designed to withstand significant internal pressure. The valve assembly controls the flow of the product and can be engineered to produce different spray patterns. Safety is a key consideration, and cans are subject to strict regulations regarding their construction, labeling, and disposal. Improper handling or disposal can lead to explosions or environmental contamination. Recycling programs are available for many types of aerosol cans, but specific guidelines vary by region.
