Emergency blanket is widely used in mountaineering, fire fighting and rescue internationally. In fact, it is very simple. Generally, it is an aluminum-plastic composite film with a very light weight of about ten grams. Then someone asked, how much use can such a light thing have?
Let's take a look at the application scope and principle of emergency blanket. Emergency blanket is mainly used in cold places to prevent people from dying due to hypothermic body temperature. Therefore, it is common to use emergency blanket to include the body after being rescued after climbing snow mountain in an emergency. Someone will ask when seeing this, just said it is a layer of composite film, how can it keep warm? Next, let's look at the principle of keeping warm.
There are mainly two ways to keep warm. One way is to add a warm layer. The warm layer is generally a fluffy substance, and the air mixed with fluffy air is used to form a non-flowing air layer on the surface of the object. The air itself is a bad conductor of heat, so it can play a certain role in keeping warm. Generally, down and cotton are all used to keep warm in this way. The second way is to keep warm with heat reflecting. Use highly reflective materials to reflect the heat radiation back. We all know that white clothes are cooler than black clothes because white reflection is stronger than black, which can reflect sunlight back. Emergency Blanket combines these two principles. One function of the aluminum film in aluminum plastic film is to ensure a layer of air on the surface of the human body is stable and not flowing. Its main function is that aluminum is a highly reflective material, which can reflect back the heat radiation emitted by the human body, its heat reflection efficiency is as high90% above. This effectively reduces the heat dissipation speed of the human body. Because aluminum belongs to metal, it is easier to tear and has low strength. Therefore, the main purpose of the composite plastic film is to increase the toughness and strength by emergency blanket.
Usually emergency blanket is about two meters long and wide, so that it can completely cover the body. Some emergency blanket are simply made into envelope sleeping bags. At the critical moment, just put people in directly. The folded emergency blanket is only half the size of the palm, and the thickness is only a few millimeters. There will be no burden for such a thing in the bag. The price of imports is about 100 yuan, while the domestic ones are only more than ten yuan. In fact, such things are very simple and have no technological content and technological requirements. To put it simply, it is a large candy wrap. Therefore, domestic ones are enough.
What is the purpose of emergency blanket in outdoor sports? The purpose of climbing Snow Mountain is needless to say here, it must be something that you carry with you. In general, everyone should have one outdoors. When going out in winter, once the weather changes and the sleeping bag temperature is not enough, on the one hand, emergency blanket can be spread in the tent. Another way is to include emergency blanket outside the sleeping bag, which can make you sleep comfortably. In summer, if you accidentally fall into the water or encounter heavy rain and your whole body is wet, the emergency blanket advantage is that even if you soak it in the water completely, just open it and shake off the water drops when using it, it will not affect the thermal insulation effect at all. When it rains, it can also be urgently used to build temporary tents or temporary poncho. And no matter in winter or summer, emergency blanket is your sleeping bag when you need to spend the night in the mountains without any equipment. Can provide more security for life.
Although this kind of thing is insignificant, it can play such a big role in the critical time. Each person prepares one, which is to add an insurance for life, which makes us happier, feel free to enjoy the good outdoor time.
