The idea of aerosol refers to very small particles that remain suspended in the air.
Aerosol is a concept that refers to very small particles of liquids or solids that remain suspended in the air . The term, which comes from the French word aerosol , also refers to the liquid that is stored under pressure and expelled as an aerosol and to the container that houses these liquids.
For example: "I don't like aerosol perfumes: I prefer traditional liquids" , "A group of vandals damaged the new sculpture with spray paint" , "I always carry pepper spray with me to defend myself in case someone wants me." steal or attack .
Aerosol types
An aerosol, thus, can be a vaporizer , spray or spray . These containers contain a liquid that is expelled through a spout or an opening located in the upper sector. When the person presses a button, a mechanism is activated that allows the liquid to be expelled in small droplets.
It is possible to find perfumes , air deodorants , insecticides , tinctures and aerosol oils . In all cases, the mode of use is similar: the user must press the button so that the liquid comes out of the container .
Spray paint can be used to create works of art or to vandalize.
From art to vandalism
Spray paint is also very common. The drawings and texts created with this type of paint are called graffiti . These spray paints are usually used for the development of urban art , although they are also used for vandalism, damaging public space.
But spray paint is not synonymous with vandalism ; On the contrary, there are many artists who practice it legally and respectfully, since it allows them to create works that are very different from traditional ones, such as oil or acrylic painting. In addition, this material can be applied to many surfaces with diverse characteristics, and this allows not only to create murals, but also to decorate and renew countless objects.
Although to achieve an admirable result it is necessary to have talent and experience, one of the most attractive points of spray painting is that it does not require technical knowledge to take the first steps : unlike watercolor , for example, there is no period of preparation that can lead to complete failure, such as applying too much water to the mixture.
Aerosols and pollution
In the field of environmental engineering , finally, an aerosol is a colloidal suspension of particles that are present in a gas . A dust storm or the dispersion of volcanic ash can generate these aerosols. From this technical point of view, some examples of aerosols are smog, smoke and oceanic mist, unlike the meaning explained in the previous paragraphs, which refers to a floating matter contained in a can, generally used for create paintings on the walls of public roads.
Aerosols have a considerable impact on environmental pollution . Some of those created because of human activities; That is, anthropogenic , can exert an action of lowering the temperature; such is the case of sulfate from fossil combustion. This affects the climate and slightly opposes the warming induced by carbon dioxide and other greenhouse gases . Climate models from various research works explain this effect: it is possible that the carbon sink is increasing in our planet's ecosystem due to the diffusion of aerosols from light.
Another important change due to aerosols is the displacement of tropical rains in the direction of the southern hemisphere, both from the east and the west, a phenomenon that is attributed to the aerosol haze of the Asian continent, according to various studies about the decrease of rainfall and the consequent drought.
