[China Glass Network] The beauty of "seeing flowers in the fog" does have another artistic conception. However, for a friend who drives a car, "seeing the road in the fog" is absolutely impossible. For the cold northern city, when you get ready to drive to work early, it is not uncommon to find the glass fog of your car. Are you drying with a cloth or with an air conditioner? What other solutions can we solve for the water mist inside the car? The Defogging Raiders will answer you.
First, the production of fog
Regarding the principle of the generation of fog in the window, we will not make complicated descriptions. Simply put, it is caused by the temperature difference of "external cold internal heat". The temperature inside the car is higher than the outdoor temperature, and the fog is formed. The water mist we refer to in this article refers to the inside of the glass, so the wiper does not function much.
Second, the method of defogging
There are many ways to remove fog. In fact, it is divided into two types: spending money and not spending money. Window convection does not incur additional overhead, but there are more constraints. The use of air conditioning defogging should be more common, but the opening of the cold wind or the hot air is also very particular, we will introduce you later. The market for special defogging agents is mixed, and the price range is also large and it is not easy to distinguish. It is recommended that you make homemade defogging agents. We will introduce them in detail.
1. Window convection
If it is found that the fog inside the car is not large, we can open a gap between the windows on both sides, so that the air inside and outside the car forms convection, the temperature difference will also decrease, and the fog will slowly disappear. The principle of this method is the same as that of air conditioning and cold air, but does not increase fuel consumption. The drawbacks of window convection are very obvious. Rain, snow, highway, and fog are not available, and opening the window will reduce the temperature inside the car.
2. Air conditioning system
For most car owners, the use of air conditioning systems for defogging is more common. Nowadays, under the basic windshield of all the cars on the market, there are air-conditioning outlets. Just select the air conditioner to the corresponding gear position and use the air blown out by the air conditioner to remove the fog. But is it cold or warm? Cold/warm winds have their own advantages and disadvantages. If you are on the road, you can use the cold wind to respond. In most cases we recommend that you use a warm air.
Turn on the fan and the cooling switch inside the car. The cold air will blow out to the front windshield and the fog will disappear quickly. The effect is very direct. But this method has a big drawback, that is, people in the car will feel very cold. In the cold winter, the air-conditioning cold wind is not good. And after the cold air is turned off, the fog may appear again. Therefore, we do not recommend the use of cold wind defogging.
The effect of blowing glass with hot air is better than blowing with cold air. However, since the water temperature is very low when it is started, it takes a while for the air conditioner to blow out the hot air, so the time is longer than blowing with cold air. At the beginning, the fog inside the car will become bigger. This is because the temperature difference between the inside and the outside is even greater. After the hot air dries the water inside the car, the fog will disappear. Special note: If you use this method, please use the warm air to remove the fog before driving, waiting for the fog to completely disappear on the road.
3. Defogging agent
Auto parts city, supermarkets and many other places have been sold. Spraying the defogging agent onto the inner surface of the automobile glass and wiping it cleanly, while removing the glass dirt, it can also form a protective film to prevent the fog layer formed by the condensation of water vapor on the glass, and the anti-fog can be sprayed once for ten days. about. The price ranges from a dozen yuan to a hundred yuan. At present, the defogging agent market is mixed, and it is easy to buy products that are not effective. In fact, we don't have to spend money to make it.
In fact, we can completely blend the "anti-fogging agent" on our own, and the effect is not bad. The simpler method is to use the washing spirit to blend. The washing spirit and water are blended in a ratio of 1:10, and then applied to the inside of the front and rear windshield with a clean soft cloth, or can be poured into a small watering can. This method is very simple and saves money. I recommend you try it.
