aerosol

Is named aerosol at 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 liquid which is stored under pressure and expelled as an aerosol and at container that houses these fluids.

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 to rob or attack me".

An aerosol can thus be a vaporizer, sprayer or spray. These containers contain a liquid that is expelled through a spout or an opening that is located in the upper sector. When the person Press a button, a mechanism is activated that allows the liquid to be expelled in small drops.

It's possible to find perfumes, room deodorants, insecticides, tinctures Y oils in aerosol. In all cases, the mode of use is similar: the user must press the button so that the liquid comes out of the container.

The spray paint it is also very common. Drawings and texts created with this kind of paint are called graffiti. These aerosol paints are often used for the development of art urban, 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 in a legal and respectful way, since it allows them to create works that are very different from traditional ones, such as oil painting. oil or acrylic. 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 renovate a myriad of objects.

Although talent and experience are necessary to achieve an admirable result, one of the most attractive things about spray paint is that does not require technical knowledge to take the first steps: unlike the watercolorFor example, there is no preparation period that can lead to a complete failure, such as applying too much water to the mix.

In the field of environmental engineeringFinally, 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 the smog, smoke and oceanic mist, unlike the meaning set out in the previous paragraphs, which refers to a floating matter contained in a can, generally used to create paintings on the walls of public roads.

Aerosols have a considerable impact on the contamination of the environment. Some of those created by human activities, that is, the anthropogenic, can exert an action to lower the temperature; such is the case of sulfate from fossil combustion. This affects the climate and is slightly opposed to 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 the ecosystem of our planet due to the diffusion of light aerosols.

Another important change caused by aerosols is the displacement of tropical rains in the direction of the southern hemisphere, both from the east and from the west, a phenomenon which is adduced to the aerosol haze of the Asian continent, according to various studies about the decrease in rainfall and the consequent drought.
