[China Glass Net] Winter in Beijing is extremely cold. Under continuous low temperature, many car owners have replaced the glass water with antifreeze function for the vehicle. However, anti-freeze glass water is really antifreeze? Recently, Mr. Li told reporters that the glass water in his car can stand up to the low temperature of -25 °C, and the product's outer packaging is also so publicized. However, after stopping for one night on the side of the road, the glass water was frozen the next day. People have to question why these antifreeze glass waters can't withstand the test of -10 °C.
The reporter survey found that the price of glass water sold in the market is very different. After 8 hours of extreme cold test, most of the glass water produced by regular manufacturers can withstand the test, but the glass water diluted with water is frozen. The maintenance master of the 4S shop told the reporter that the glass water added by Mr. Li is probably diluted with water. In addition, if it is used in the ordinary type of glass water used in the summer, and then added anti-freeze type glass water, it is still easy to freeze.

Antifreeze glass water is frequently frozen
"I added the anti-freeze glass water, but before I went out, I sprayed the glass and the glass water was frozen. I couldn't spray it completely." Mr. Li said that he had been washing the car in a car wash. He had just let it go a while ago. The clerk of the car wash line helped fill the glass of water. Because he lived in the old community, Mr. Li parked his car on the side of the road every night, so every time he drove in the morning, he developed a habit and cleaned the window. Closer to this time, every time he cleans the car glass every morning, no glass water flows out no matter how it is sprayed. Only the wiper swayed on the dusty window.
"I use the glass water with an antifreeze index of -25 °C. Although Beijing is very cold during this time, the lower temperature in the evening is only about -10 °C. How can the glass water freeze?" Mr. Li suspected that he had bought it. Fake goods. In order to verify, he also confirmed the remaining glass water in the freezer of the refrigerator. As a result, in less than 4 hours, the glass water was frozen into ice.
However, how can the glass water that has been added to the car be used up as soon as possible? Mr. Li has tried his best. In the past few days, every time he went on the road, the water tank of the glass water was naturally frozen, and then it was sprayed. After repeated this many times, the glass water that was not frozen was finally sprayed. "I really shouldn't be greedy. I knew that it was so troublesome. I bought a glass of good quality at the beginning." Mr. Li said that he only spent 5 yuan on this bottle of glass water, and the common antifreeze glass on the market. The price is usually above 10 yuan.
survey
Antifreeze glass water price is too great
Yesterday afternoon, the reporter visited a number of auto repair shops and auto parts city. Many merchants have neatly arranged a row of anti-freeze glass water in a prominent position in the store. In the International Auto Parts City of the City Ring City, which is close to the South Fourth Ring Road, the reporter investigated a circle and found that the price gap between antifreeze glass water is very different. Cheaper, as long as 5 yuan per bottle; in the middle and high-end price of glass water, the wholesale price is mostly between 8 yuan and 15 yuan.
A shop owner told reporters that since the winter, this kind of anti-freeze glass water has sold very well, and the sales volume has risen remarkably. Many people directly approve one box, one box of 12 bottles, three or five friends, one point, than the outside retail can A lot cheaper. And the anti-freeze effect of the glass water? The boss patted his chest to ensure that the 10 yuan or so is definitely no problem, will not freeze. But 5 yuan is hard to say. The reporter carefully looked at it and found that no matter what kind of glass water, even if it is cheaper, the bottle is printed with the words "-25 °C", and the anti-freeze index of individual brands even reached -40 °C.
Afterwards, the reporter saw on the Internet again that Taobao sold the top stores, and the anti-freeze glass water sold more than 10,000 pieces per month, and the brands had dozens of brands. However, from the price point of view, some 2 liters to 30 yuan a bottle, and some only sell 3 yuan, the price difference is ten times. Cheaper, the whole box wholesale as long as 2.5 yuan a bottle, the difference is very different.
test
Regular glass water is mostly resistant to low temperatures
It is understood that in anti-freeze type glass water, the main anti-freezing effect is alcohol and ethylene glycol, which can reduce the freezing point of liquid, thereby preventing frost and quickly dissolving frost. Then, the case of Mr. Li, the owner of the car, is still a common case. Yesterday afternoon, the reporter bought 6 bottles of antifreeze glass water and 1 bottle of ordinary glass water from the supermarket, gas station and auto parts city for testing.
