Why do balloons leak and how to prevent?

Why latex balloons leak?

1. Latex balloons are mostly the use of air, so that it will not float empty, and there will be no danger, the leakage phenomenon of latex balloons is generally not tied at the inflation port, and it is necessary to re-fix the latex balloon seal.

2. The ball body of the balloon leaks, because the latex balloon is very elastic, it can not be repaired like the foil balloon, so if the ball body of the latex balloon leaks, it can be replaced and used.

3. The balloon leak is not the balloon burst, but the air molecules inside are in motion, in physics, there is a gap between any molecule, the air molecules in the balloon also have a gap.

Although at the beginning, the balloon is very full, but after a period of time, the movement of the molecules inside to fill some of the gaps, simply put, is squeezed into a ball, there is no gap, relatively, the space left will become larger, so the balloon will deflate, this is a normal phenomenon, but usually appear after 3-5 days.

--The reason of foil balloon leakage

1. Influence of temperature difference. Ten balloons were filled with helium at 34 degrees Celsius and then placed at 24 degrees Celsius. Two hours later, all 10 balloons looked noticeably deflated. Said he didn't look full when he first inflated, but he still floated. Instead, the 10 balloons were placed at 34 degrees Celsius, and after an hour or two they popped up again. Therefore, temperature still has an effect on air leakage. Of course, this is just the principle of heat expansion and cold contraction. So when we inflate and use aluminum balloons, we try to choose the same environment.

2. The impact of materials is usually when customers ask about the quality standards or general quality requirements for exports. If customers export to Europe and the United States, we generally recommend customers to use nylon materials. The relative tightness and fastness of nylon material is better than that of PET material, and the feel is soft. Of course, the relative price will be a little higher. If the customer's quality requirements are not very high, and the price is cheap, we will tell the customer to use PET as the material. Compared with nylon, the gas retention and fastness of PET will be poor.

3. Influence of production process. So far, there are two production processes for the production of foil balloons, one is cold trimming and the other is hot trimming. Cold cutting technology has only one seal. Cut edge cold cut, cut out the shape of the foil balloon. It's not sealed on the sides. Its advantage is that the production speed is fast, and the relative production cost will be reduced. The hot-trimmed aluminum foil balloon has a seal on the side, which means there are two seals to prevent helium gas. It's leaking from the side seal.

4. The impact of inflation pressure, when we inflate the aluminum foil balloon, try to be enough at one time, do not worry about the balloon burst, then how to judge whether the balloon is enough? When we inflated the balloon, it was already difficult to touch it with one hand. This means that there is enough, or just put the inflated balloon on the ground and only hear the rumbling sound. So why do we need enough to inflate the balloon for the first time? Our current balloons are self-sealing air nozzles. When we inflate the balloon, the gas passes through the automatic sealing. There will be gaps when inflated. To close this gap, we need to inflate enough to fill the inside of the balloon. A certain pressure will be formed, and the pressure will return the automatic sealing nozzle to its original closed state, so that we can ensure that our inflated air does not leak out of the automatic sealing.

How to prevent the leakage of balloon?

1. In order to prevent the leakage of balloons, we should have requirements for the quality of balloons, whether it is foil balloons or latex balloons, we should choose thicker, higher quality balloons to use, so as to avoid the phenomenon of leakage in the process of use.

2. the balloon to prevent air leakage, when inflating must be filled according to the size of the balloon into the appropriate amount of gas, so as to prevent the balloon because of excessive inflation, can not withstand the phenomenon of air leakage.

3.the storage environment of the balloon after inflation is also very important, if not immediately used, then it should be stored in a cool and dry place, can not be stored in a high temperature environment, and away from some sharp objects.

4.in order to smooth the scene of balloon decoration, or to prevent the problem of balloon leakage, so when decorating, some spare balloons should be reserved to prevent accidents.
