Why is the refrigerator frosted?
Living at home, the refrigerator is indispensable. Frost on the inside of the refrigerator, where does the water vapor come from?
It is understood that most of the water vapor comes from the air. When people store food and open the refrigerator, the indoor air and the gas in the refrigerator are freely exchanged, and the indoor humid air quietly enters the refrigerator. There is also a part of the water vapor from the food stored in the refrigerator, such as clean vegetables, fruits in the crisper, the water in the food such as vegetables evaporates, and then condenses into frost after the cold. Especially in the summer, the indoor temperature is high, the humidity is high, and the temperature difference between the room temperature and the refrigerator is large. When the refrigerator is turned on, a cool air flows out from the inside and the indoor air is drilled into the refrigerator. A little time, a layer of hoarfrost appeared on the surface of the refrigerator. It has also been found that even if nothing is left in the refrigerator, a thick layer of frost will form inside the often opened refrigerator, and it is obvious that a large part of the water vapor in the refrigerator comes from the air vapor.
Refrigerator defrost has a high trick
Some refrigerators require defrosting, and artificial refrigerator defrosting is time consuming and laborious, and the defrosting effect is very poor. Here I recommend a defrost trick.
According to the size of the refrigerator freezer, cut a piece of thick plastic film and stick it on the frosted wall of the refrigerator. You don't need any glue to make it. When defrosting, temporarily take out the food in the refrigerator, then peel off the plastic film, the frost can all fall off, then re-attach a film, put in the food, and continue to use.
Metal silicon, also known as crystalline silicon or industrial silicon, is primarily used as an additive for non-ferrous alloys. Metal silicon is produced from quartz and coke smelted in an electric furnace. The content of main component silicon is about 98% (In recent years, 99.99% of Si is contained in metallic silicon), and the remaining impurities are iron and aluminum. , calcium and so on.
