1. Inflate with a hydrogen bottle:
Open the valve of the hydrogen bottle and insert the nozzle of the hydrogen bottle into the inflation port of the hydrogen balloon; Slowly open the valve of the hydrogen bottle to let the hydrogen flow out from the nozzle of the hydrogen bottle and fill the hydrogen balloon; When the hydrogen balloon expands to the required size, the valve of the hydrogen bottle is closed, and the nozzle of the hydrogen bottle is pulled out from the inflation port of the hydrogen balloon to complete inflation.
2. Use hydrogen generator to inflate:
Insert the nozzle of the hydrogen generator into the inflation port of the hydrogen balloon; Open the hydrogen generator, let the hydrogen flow out from the nozzle of the hydrogen generator and fill the hydrogen balloon; When the hydrogen balloon expands to the required size, the hydrogen generator is turned off, and the nozzle of the hydrogen generator is pulled out from the inflation port of the hydrogen balloon to complete inflation.
1. What is a hydrogen balloon?
Hydrogen balloon is a kind of light bag-like or sac-like object filled with hydrogen, which is the lightest and has a density of 0.0899 g per liter. An object that can float upward by the buoyancy of hydrogen is called a hydrogen balloon. Hydrogen balloons generally include rubber hydrogen balloons, plastic film hydrogen balloons and cloth-coated hydrogen balloons. Smaller hydrogen balloons are currently used for children's toys or holiday flights.
Larger hydrogen balloons are used to hang advertising banners, also known as floating hydrogen balloons. In meteorology, hydrogen balloons are used to detect high altitude. In military, hydrogen balloons are used to set up communication antennas or distribute leaflets. The internal frequency of the hydrogen balloon is close to 20Hz.
2. The principle of balloon liftoff
Balloons are influenced by their own gravity and air buoyancy. Self-gravity = balloon gravity+hydrogen gravity in the ball; Air buoyancy = average air density *g* balloon volume, according to Newton's second law: air buoyancy-dead weight = ma>0.
3. The danger of hydrogen balloons
Because hydrogen is cheaper than inert gases such as helium, hydrogen balloons are basically sold in the market. When hydrogen rubs against other objects to generate static electricity, it is easy to explode or burn when it meets an open flame. In addition, the balloons of colorful vendors sold in the market are mostly hydrogen balloons filled with hydrogen, and helium balloons filled with helium are safer.
