Glancing around the apartment, people do not even think about how densely aerosols have entered their lives. But some of them are used daily and more than once. So what are aerosols? What are the types of aerosols? In what areas of life are they used?
Definition
Aerosol is a deodorant, and a can of paint, and hairspray. In medicine, aerosols are used to spray an antibiotic or antiseptic. Inhalers for people with asthma or other respiratory problems also fall into this category.
Aerosol can also be found in household chemicals, and even as a disinfectant or insect repellant, such as mosquitoes. Women often use different substances for hair and body care, which are also essentially aerosols - hairspray, deodorant, and so on.
From the above, it becomes obvious that aerosol is the smallest particles that hang in a gaseous medium. It can be both liquid and solid particles. We can say that fog or smoke is also a kind of aerosol. These smallthe particles are so tiny that they cannot fall to the ground. They are kept suspended by constant air currents.
Types of aerosol systems
The most common type of aerosol can be considered two-phase systems. The system got its name because of the state of aggregation of the contents of the jar. To understand which aerosol is in the hands, the instruction describes in detail. Most often, such systems need to be shaken before use.
This action is necessary in order to mix the gas compressed in the cylinder and the volatile components of the concentrate, which is in a liquefied state. What comes out of the can when pressed is either foam or a light mist. This type is often used in cosmetics and burn products.
Another type, which is also called an aerosol, is a solution one. In such systems, the active substance is dissolved in a propellant or similar solvent. When the aerosol is released from the can, the chemical additive evaporates and the aerosol is obtained in a pure form in a fog state.
The last type of aerosol systems can be considered three-phase. These are the most complex aerosols, since they contain three substances of different aggregate states. When you press the bottle button, a person often sees foam. Such aerosols are actively used in medicine.
Spray Types
In order to apply an aerosol, spray is used. It comes in three types:
- with the help of nozzles - this is the output of liquid under pressure underpressure;
- rotating disk;
- using ultrasound.
Of course, you can find other ways of such painstaking work, everyone has seen and used them at least once in their life in the form of a spray gun, broomizer or aerosol generator.
Paints
In addition to medicine, the aerosol has firmly entered the domestic sphere. Its best entry can be considered the use of aerosols in paints. How?
Spray paint is a ready-made coloring mixture, which is enclosed in a special package. It is applied by spraying and has a number of advantages over conventional acrylic and other paints. What?
- Easy to apply. Even a child can handle the aerosol.
- No need to buy extra tools like brushes and rollers. This significantly reduces costs.
- The dye does not need to be stirred, it is already ready to use.
- Spray paint is quick to apply and dry, making it easier to make a solid surface.
But, despite such an abundance of advantages, work with aerosols must be carried out strictly according to the instructions indicated on the package.
Aerosol and safety
Aerosol is a highly volatile mixture that spreads easily through the air. Therefore, the first and foremost rule in working with this type of dye is to work in well-ventilated areas.
Repeating about the volatility of substances, you should be aware that you need to work with a can only in goggles or a respirator. It can save not onlyyour eyes and airways.
It is worth remembering that the composition in the cylinder is explosive, so do not experiment by spraying the contents of the can over the fire or pierce it. Consequences can cost limbs or even life.
Repair, home and medicine?
Spray paint is a very popular item. Why? It is often used to color handmade crafts. Then there are no brush marks, and the colors in spray paints are often more saturated.
Aerosol is the same air freshener in an apartment or bathroom. In its composition, in addition to the aerosol itself and the deterrent component, oils and fragrances are added in high concentrations.
By the way, there are systems that cooperate with aerosols without human intervention. We are talking about automatic fresheners. The principle of their operation is based on the fact that from time to time the device sends a signal to a special tube that is connected to the cylinder, releasing aromatic gas from it. These air fresheners are unpretentious, and all you need to make them work is to change the bottle and monitor the battery charge.
In addition, sometimes such systems are used to spray timed disinfectants, also in aerosol format. With this kind of automation, you never miss a fixed schedule.
Conclusion
Of course, the definition of an aerosol is more than just particles of matter that float in the air. But it is customary for modern man to call everything thatsprayed from a can. This is partly correct, but not entirely.
Aerosols are used both for cosmetic purposes and to help the sick, to disinfect hands or a room, give it a pleasant aroma and give the surface the desired color. There are so many uses for aerosol that people simply do not notice how they continue to use them. Even just to wipe the LCD monitor, people will use a special spray.
Care must be taken when working with aerosols. It is strictly forbidden to give cylinders with this substance to children. As well as trying to disassemble the cylinder yourself.
