How does the hand sanitizer create foam?
How does the hand sanitizer create foam? It is caused by air pressure. The hand washing liquid is manually pressurized to hydraulically wash the hands. The mousse bottle is with high pressure when it is filled. It has pressure and will automatically spray as long as the bottle mouth is pressed.
Compared with ordinary hand sanitizers, foam hand sanitizers have innovative breakthroughs in function and concept. To put it simply, the foam is relatively rich, and the foam is directly pressed. It can be disposable or washed. This type of foaming hand sanitizer is relatively water-saving to clean and relatively clean and easy to rinse. The principle is that there is a special device at the mouth of the bottle to fully mix the air with the foaming agent. I haven’t seen a foam gun for firefighting. I must have done such an experiment in a middle school. The drooping paper floats to the place where the gas flows, because the fluid has a decompression effect. The foam gun has a common nozzle in the middle, and there is a hole with many holes on the side. When the foaming agent is sprayed from the middle of the sleeve, a large amount of air is drawn in from the side due to the decrease in air pressure, and it is mixed with it to generate foam.
