Hot summer
Author:China Science and Technology M Time:2022.08.03
Recently, most parts of my country are undergoing high temperature and heat waves, and high temperature weather at 389 degrees is common. do you know? Under such high temperature exposure, outdoor public facilities and cars can even reach the temperature of 60 or 70 degrees. If the contact time is too long, it may burn the skin.
What is particularly hot in the sun?
The front of the car covers eggs, slide barbecue ... These are not only the ridicule of high -temperature weather, but also reporters and curious netizens have done experiments. Put the eggs and bacon on the tin foil and place it on the hood before the car. Although it is not completely cooked, after an hour or two of the sunlight "barbecue", you can also bake a hearty egg.
Let's take a look together. What are the most hot in the sun?
The above measurement data comes from the network. The measurement results of the temperature will be affected by many factors such as object materials, duration of light, or direct radiation. It is for reference only and is not absolute.
The temperature in the car is high, and the lighter is easy to explode
In summer, after the car is exposed to the sun, the temperature in the car will be 50%-85%higher than the outdoor temperature. In a high temperature and closed environment, it may occur in the high temperature and the closed environment. Essence
Some journalists have done experiments in the exposure of the fire locomotive. Two ordinary lighters are placed on the front platform of the car and accepted the sun in the afternoon of about 38 ° C. In the 12th and 25th minute, the two lighters are Both exploded, and the moment of the explosion was less than a second. The lighter fry into fragments and splashed around the car. Most of the fuel used in the lighter uses butane, propane, and oil liquefaction gas. They are charged into a closed air box after pressurizing. Once they are released to the air, they will swell quickly and are easily ignited. Therefore, putting a lighter in the summer is equivalent to a dangerous time -like bomb.
In addition to the lighter, perfume bottles, bottled water, jar drinks, etc. are not easy to place in the car.
Low temperature may also cause burns
Low -temperature burns refer to burns caused by low -thermal objects that are higher than body temperature for a long time. The temperature of contacting 70 ° C lasts for one minute, and the skin may be burned; and when the skin contacts nearly 60 ° C for more than five minutes, it may also cause burns. This scald is called "low temperature burns".
After the sun exposure, the facilities such as fitness equipment, children's slides and other facilities may cause low temperature burns to artificially, especially children who are delicate and lack of self -protection, which can easily cause damage.
The skin and low -temperature heat sources are in short -term contact, which only causes the shallow blisters of the leather. However, if the low temperature thermal source continues, it will gradually develop into deep leather and subcutaneous tissue burns. The low temperature burns are different from the burns caused by high temperature, and the pain of the wound is not very obvious. It only occurs on the skin of redness, blisters, peeling or whitening. The area is not large. In severe cases, even deep tissue necrosis will be caused. If it is not handled properly, severe ulcers will occur, and it will not heal for a long time.
If you are accidentally burned by low temperature, you must first apply it through cold water or ice cubes. Those who are light can apply the corresponding burns, and if you are serious, you should seek medical treatment immediately.
