As modern life becomes more and more sophisticated in atmosphere and style, it is often inseparable from the decoration of helium balloons. There is a large demand for helium in events, parties, birthdays, wedding decorations and other scenes, while traditional methods The high-pressure helium gas is too heavy to carry. Therefore, the helium tank is light in weight, convenient to carry, and simple to operate. It is the best choice for decorations such as helium balloons.

The composition of the helium tank is helium, which is a colorless, odorless, and odorless gaseous inert gas at room temperature. It has a low critical temperature and is a difficult-to-liquefy gas found in nature. The chemical nature of helium is extremely inactive and cannot be incinerated. Does not support combustion. The content of helium in the air is about 5.2 parts per million, which can theoretically be extracted from the air, but because its content is too thin, the cost of separation is high.

Due to its inactive chemical properties and lighter than air characteristics, helium is often used as the filling gas in airships or advertising balloons, and this use is also well known.
