[Knowledge of the car owner's family car]According to the theory of traditional medicine, winter is the time to hide the essence. As the saying goes, "Three nines make up one winter, and there will be no pain in the coming year". Similarly, the maintenance of vehicles in winter is particularly important to prevent medium and heavy maintenance. In winter, the front windshield is prone to icing when it rains and sleet, especially after the vehicle is parked overnight, when the temperature is below zero, the front windshield is prone to icing. In order to remove these frosts, many cars will consume a lot of time, and even cause many car owners to delay working hours. Today, the editor deliberately finds some solutions for your reference to help car owners avoid some car troubles.
The main reasons for the icing of car glass:
After the person leaves the car, there is still hot air inside the car, making the car glass still hot. When the snow falls on the glass, it melts first; during the melting of the snow, the temperature inside the car gradually decreases until the temperature inside the car is the same as the temperature outside the car. , The melted snow on the glass began to freeze.
How to remove frost from car glass
Method 1: Deicing with warm air
The best way is to start the car, when the engine water temperature rises, use warm air to blow the windshield until the ice melts. But this method also has certain drawbacks, that is, it is time-consuming, labor-intensive, and gas-consuming. If there is no more rain or snow after the car is received, the water on the windshield can be wiped clean, so as to avoid icing on the windshield again. If it is snowing, you can wipe the windshield clean after receiving the car, and then cover the windshield with a layer of newspaper, so that you can tear off the newspaper when you leave the car, so you don’t have to worry about the windshield anymore. The ice is frozen.
Method 2: Physical deicing
The owner can prepare a hard plastic scraper. Of course, a special glass frost shovel can also be used. The glass frost shovel is more convenient and quicker, and does not freeze your hands. When there is snow and ice on the glass, use a plastic scraper or glass frost shovel to remove it. However, Geely Global Hawk's Gaomi Runfu first-level service station reminds car owners that when removing ice and snow, they must prevent the glass from being scratched. Plastic scrapers or glass frost shovel cannot be scraped back and forth, and should be pushed in the same direction.
Method 3: Chemical deicing
When car windows freeze in winter, remember not to use hot water to melt ice. Although hot water melts ice much faster than warm water, it is very dangerous, and it is easy for the windshield to burst. After all, the temperature difference is too large. Using cold water will also damage the paint, and the frost may be more serious afterwards. When the icing of the current windshield is not very thick, you can use a rag to rinse it in warm water of 40-50 degrees, then gently wipe the windshield, and then rinse with warm water of about 40 degrees. Once flushed, it can usually be flushed clean. If the windshield is thicker, turn on the vehicle while using warm water to melt the ice. After the car water temperature indicator is in the middle (about 70 or 80 degrees), twist the warm air to blow toward the windshield, and turn it on to the maximum. After a while, the glass will heat up, and the icing will easily melt away.
In addition, ifcarDon’t drive for the time being. When the sun is good, you can drive the car under the sun until the ice melts. Although this method is time-consuming, it is more economical and less troublesome.
2. Cold and warm wind eliminates car window fog
Driving in winter, due to the large temperature difference between inside and outside, it is easy to form fog in the car, which affects the driver's line of sight. There are two ways to eliminate fog, one is cold air defogging, and the other is warm air defogging. Both methods can help us eliminate the fog on the glass. Of course, we need to adjust the adjustment knob of the air outlet to the position of the front windshield or press the defogging button.
Due to the low temperature in winter, the cold wind defogging method makes the interior comfort of the car poor, and it is generally rarely used.The air that enters the car from the external circulation, and the warm air blown out after the engine is preheated, can not only defogging but also heating, plus no need to startcompressor, The fuel consumption is naturally reduced, making it easier for everyone to accept. But on rainy days in winter, due to the relatively high humidity in the air, the effect of using heating to defog is not obvious, and sometimes the fog will be repeated. At this time, the last solution is to use air-conditioning for heating. In addition to adjusting the temperature, the air conditioner also has the most important function of dehumidification.
