1, The function of emergency blankets
The main function of a first aid blanket is to provide emergency warmth in outdoor environments. The first aid blanket is small in size and easy to carry. When there is an injured person or a phenomenon of hypothermia, immediately cover or cover the body with a first aid blanket to prevent a sudden drop in body temperature. Spread out; And the golden side is beyond the outside, which can better absorb heat, combine the inside and outside, and effectively preserve body temperature, thus avoiding the occurrence of hypothermia accidents outdoors. Of course, if it's convenient for rescue, you still need to wear the silver side on the outside.
It has a small size and is very easy to carry. After folding, it is only the size of a palm. When unfolded, it becomes a silver film that can wrap around your entire body. The life blanket is coated with silver and gold aluminum foil on both sides, and weighs very light, about ten grams. Seemingly unremarkable, its functions are exceptionally powerful. In low temperature environments, wearing it can maintain 80% of its own heat without dissipating.
Note: The normal silver side faces inward because silver can reflect body temperature back, so more than 80% of body temperature will not be emitted.
2, The principle of keeping warm with first aid blankets
1. Add insulation layer to keep warm
The insulation layer is usually a fluffy substance that uses the air mixed in after fluffiness to form a non flowing air layer on the surface of the object. And air itself is a poor conductor of heat, so it can play a certain role in keeping warm. Generally, down, cotton, etc. use this method to keep warm. The aluminum film in the emergency blanket aluminum-plastic film uses this principle to ensure a stable and non flowing layer of air on the surface of the human body.
2. Heat reflective insulation
Use highly reflective materials to reflect thermal radiation back. We all know that white clothes are cooler than black clothes because they reflect sunlight more strongly than black. The aluminum contained in the emergency blanket is a highly reflective material that can reflect back the heat radiation emitted by the human body, with a heat reflection efficiency of over 90%. This effectively reduces the speed of human body heat dissipation.
3, Emergency blankets have other functions outdoors
1. Can be used as a reflective film to send positioning signals to airborne or search and rescue personnel.
2. When it rains outdoors, it can also be used as an emergency rain cover. And it can also be used to build emergency windproof and rainproof shelters.
3. When encountering glaciers, it can also be used to wrap the feet, prevent water and cold, and wade through water.
4. The first aid blanket can also provide sun protection when worn on the head, face, and body.
5. In emergency situations, it can also be twisted into ropes for fixing and tying.
6. In outdoor backlit photography, it can also be used as a reflector to fill in the light on the subject's face~
Although the first aid blanket is small, it has many functions. Don't forget to bring the first aid blanket when exercising outdoors!
