In general, a hydrogen balloon is filled with hydrogen gas, which floats upward by its buoyancy. Hydrogen is a non-toxic gas, but the chemical properties are lively, prone to accidents, so the use of hydrogen balloons need to be careful not to friction with other objects to produce static electricity, or encounter open flame, high temperature, electric spark.
A hydrogen balloon is a lightweight bag or sac-like object filled with hydrogen gas that floats upward by its buoyancy.
Normally, a hydrogen balloon is filled with hydrogen gas.
The hydrogen inside the hydrogen balloon is generally through sodium hydroxide + water + aluminum, to produce hydrogen and aluminum hydroxide and sodium metaaluminate mixture.
Hydrogen balloons are generally rubber hydrogen balloons, plastic film hydrogen balloons and cloth coated hydrogen balloons. At present, the smaller hydrogen balloons are mostly used for children's toys or festive release, and the larger hydrogen balloons are used for floating advertising banners, also called air floating hydrogen balloons, meteorological hydrogen balloons are used to detect high altitude, and the military uses hydrogen balloons to set up communication antennas or distribute leaflets.
The use of hydrogen balloons needs to be careful not to generate static electricity from friction with other objects, or encounter open flames, high temperatures, and electric sparks, which are prone to accidents.
