Are you looking for creative ways to put a new life into the crumbling walls of your house? Or your wife has once again made up her mind to change the color of furniture? Or maybe your kids want to retouch the old dog house for new cute pups. Well, worry not! Luckily, there is a simple solution to your all regular issues and available in a can of spray paint! Now the question is how does a can of spray paint work?
Isn’t it fun to press the nozzle ‘Psssssssttt’ and ‘boom’, colors everywhere? It is! Right? Let me tell you how this magic happens precisely.
a) When the nozzle is pressed, the button pushes the valve down.
b) As the the is tightly closed, but as soon as it goes down, the mixture rushes up the dip tube and comes out of the nozzle in a pressurized manner.
c) The one end of the dip tube surfaces to the nozzle, and the other reaches the bottom of the container. When propellant gets free of the compressed container through dip tube and oppositely, it expands and covers the targeted surface evenly. (But here comes a question that how a can of spray paint; colors the surface smoothly without causing any flaw?)
d) Before pressing the nozzle, you should always shake the can well. When the containers are shaken, the pea agitates the mixture to combine the substance and gas properly. Without a pea, the combination will spur out unevenly.

You must have heard of spray paints, also called aerosol paints. Aerosol paint is just like another Usually paint stored in a pressurized container. This container has a valve at the top that can be pressed to release the mixture of paint and propellant. The propellant can be any substance causing spurring, for instance, compressed air or pressurized gas.
Pressing the valve of spray paint container releases a colored mist that can be applied on different textured surfaces such as wood, plastic, and fabric.
You must have an idea about two primary methods of paint application:
But, use of spray paints can help you to paint quickly as well as neatly to enjoy a smooth and shinier coating.
We see cans of spray paints in garages and paint shops and use them to spread the colors according to our need. But have you ever wondered about their making and working? If yes, then continue reading!
The spray paints come in designed merely containers exhibiting the shape of a cylinder. These cans are quite light in weight and can be easily held and used by you. Cans of spray paints are made up of either steel or aluminumsugarand one spray paint can involve a valve, a dip tube, and a pea.
Using spray paint cans can be fun and comfortablecouldbut it’s time to know how that bottle of fun is prepared. To manufacture a spray paint can, a proper procedure is followed that can be broken into two parts: Construction of Can and Filling.
To construct a can, these all little items are required:
You must be thinking that a can of spray paint brings happiness and colors in your life. But this small bottle may contain toxic elements to harm you and your environment just like initial years.
Until 1978, the most popular aerosol paint manufacturers used Chlorofluorocarbons as the first prioritized propellant. Later it was discovered that Chlorofluorocarbons could cause damage to ozone layer hence their use was banned.
Then the spray paint industries began using Hydrocarbons, a mixture of hydrogen and carbon, as propellant. This alternative was also declared to be harmful in the 1980s because hydrocarbons such as methane and propane may cause smog.
Currently, the spray paint makers are using hydrofluorocarbons, a mixture of hydrogen, fluorine, and carbon. This propellant has fewer risks and doesn’t cause notable damage to the environment, but still, beware!
Since Seymour has invented magical containers confining paints, industries have begun using this invention innovatively. Let me tell you how manufacturers are using spray paint cans working strategy for designed explicitly purposes. Here are three methods of applying paints used by industries:
This method is also called powder painting that is used to apply dry paints on different types of surface. Just like the spray cans are used to release the compressed colored compound, industries use spray guns to drive the atomized color particles onto the targeted surface with the help of compressed gas. These powder-like particles get charged by the friction as they pass through the spray nozzle. Before they make the contact with targeted surface, the positively charged particles repel each other and distribute evenly. The surface of grounded item metal is negatively charged hence attract the opposite charged particles like a magnet.
The vacuum coating method is used by factories to apply liquid paint on a surface such as wood, plastic and glass. These surfaces require a thin layer of coating. During the procedure of vacuum coating, the targeted object is placed in a chamber to dip it into a paint solution or use a large nozzle to spray it. The purpose gets covered in a liquid paint evenly with a smooth coating. Then it is removed from the chamber and goes through a UV curing process. UV curing is a process of drying the object by exposing it to UV light that causes the drying faster than heat.
This method is used by companies which manufacture a small item of fewer than 4 inches. This method involves a machine that is specifically designed for Flatline spraying. The objects a into this machine for paint coating. This machine has multiple spray guns that are automated to complete a series of movements while spraying the object from every angle.
Who doesn’t like tanning? I mean brown skin is quite attractive. Isn’t it? The sun tanning and tanning beds are the popular tanning methods. But since the damage caused by ultraviolet rays has been proved, these methods are becoming less attractive. Don’t worry because you can still enjoy tanning. How? Well, salons are offering an alternative way of tanning by introducing spray-on tanning method. Once again the spray paint can working strategy saved the day!
The spray-on tanning procedure is quite similar to the function of spray paint bottles. You walk into the big booths of sprays. These can be either manual or automatic. A compressed gas will be used to apply the solution onto your skin. That solution doesn’t involve paint but dihydroxyacetone substance that is a sugar. When this material touches your dead skin, a reaction will take place, and your skin will begin turning brown temporarily.
Who knew that a spray paint can bring an exemplary change in the makeup world? Nowadays, beauticians and expert make-up artists are using small air-powered tools to apply the cosmetics. The cosmetic airbrushes work same as spray paint cans. These brushes use the pressurized air to atomize the powdered particles or liquid makeup. You can use these brushes to enjoy the smooth makeup application with an even layer. The airbrushes eliminate the chances of makeup flaws by applying the cosmetics uniformly. And let me tell you that these days television artists also use airbrushes because cameras reveal all flaws!
If you’re a graffiti artist, then you must know what I’m going to tell you! After the invention of spray paint cans, the graffiti art moved up to a whole next level!
Graffiti artists use spray paint cans as the preferred medium for painting the public places. In 1960s and 1970s, the graffiti artists’ came up on the surface and painted every street and subway of New York to highlight their artistic endeavors.
As graffiti art is done in the dark by crossing the limitations of law, the spray paint cans turned out to be an ideal tool for the artists. Spray paints are the best medium for graffiti artists, and reason are quite distinct. Spray paint cans:
Graffiti is being considered against the law and leading towards vandalism. But, this trend has evolved entirely after the invention of spray paint cans. The big companies and manufacturers are hiring graffiti artists to advertise their products through street arts for better production and sales.
Normally paints are harmful because they contain a solvent called hydrocarbon toluene. This element has the property of evaporating at room temperature. During this process of evaporation, two things happen:
These chemical vapors can be intoxicating if inhaled and can also cause high hallucination. Besides the harmful solvents, the spray paints also contain vicious aerosols that can turn out to be even more damaging. This product is available in the market and easily accessible. Which means those who want to get high can purchase a spray paint can and satisfy their narcotic addiction!
In short, a can of spray paint can do great wonders by spreading colors everywhere. These cans are manufactured with grand strategy that all you need to do is press the ‘button’ and play with colors!
