Inflatable balloon is a flexible bag filled with a gas, such as helium, hydrogen, nitrous oxide, oxygen or air. Modern balloons can be made from materials such as rubber, latex, polychloroprene, or a nylon fabric. Balloons in the previous history were made of dried animal bladder, such as pork. Some balloons are used for decorative and entertainment purposes, while others are used for practical purposes, in meteorology (weather balloon), medicine, military purposes, or in transit. Balloons are now available throughout the world due to its low cost. The inventor of the rubber balloon was Michael Faraday was born in 1824th year, which was discovered by experimenting with different gases in their time.
Party balloons are mostly made of natural latex from rubber trees processed, and can be filled with air, helium, water, or any other suitable liquid or gas. Its rubber elasticity makes balloon adjustable volume. Filling the balloon with air can be done with the mouth or using an electric compressor, hand pump or with a source of compressed gas.
When a balloon filled with helium so that they float balloons typically retain their buoyancy only a day or two, sometimes longer. The reason is that helium atoms escape through small pores in the latex which are larger than the helium atoms. Balloons filled with air usually retain their size and shape much longer, sometimes up to a week. Even a perfect rubber balloon eventually loses gas. The process by which gas migrates from a region of high concentration through a barrier or membrane in the area of lower concentration is called diffusion.
The inside of balloons can be treated with a special gel (for example, a mixture of the polymer solution and is sold under the "Hi Float" brand) which forms a film on the inside of the balloon that would shut the pores and to reduce the helium leakage, thus increasing the time flying balloons for a week or longer.
Foil - shaped balloons ( Foil Balloons )
Beginning in the late 1970s, some more expensive (and longer-lasting) foil balloons made of thin, unstretchable, less permeable metalized films such as Mylar (BOPET) have begun to produce. These balloons have attractive shiny reflective surfaces and are often made with a variety of printing color pictures and patterns for gifts. The most important attribute of metalized nylon balloons is its light weight, increased Suspensibility, and his ability to keep the helium in the balloon up to several weeks.
Modeling balloons and balloons in art ( Modeling Balloons )
Surely you've seen the balloon artists entertainers who make a dog, a sword or a flower from inflated modeling balloons which are tubular structures? They used the so-called modeling balloons to create sculptures that are made of extra-stretchy rubber so that they can be folded and bound and without breaking them. Since the pressure required to inflate a balloon is inversely proportional to the diameter of the balloon, these tiny tubular balloons inflate is extremely difficult at the beginning, and is commonly used pump to inflate these balloons.
Decoration and creation of balloons
Decorator can use helium balloons for sculpture. Usually the round shape of the balloon restricts it to simple arches or walls, of course ambitious decorators have tried other options. It is also common to use balloons decoration on the table for the celebratory events. Balloons can sometimes be modeled in the shapes of animals. Decorative "bouquet" of balloons usually occurs with three or five balloons on a complex bouquet. Decorative bouquet ribbon is attached to the end of which there is a weight that prevents bouquet crowd said further.
