The use of antifreeze is generally different according to different regions, because antifreeze is very useful in areas with cold climatic conditions, such as in Yinchuan, Ningxia, then it is necessary to prepare minus 45 better, like the southern region, it is enough to generally use minus 20 degrees, and it is generally used more in winter, because it is generally only replaced in winter, and it can be replaced at ordinary times, including the replacement of antifreeze is generally replaced at 3w-4w kilometers, generally speaking, Private cars only have a replacement cycle once a year. If my answer can help you, please give it a thank you !

If the temperature is below zero, antifreeze needs to be added. Antifreeze concrete: A substance that hardens at negative temperatures and achieves the expected performance under specified curing conditions and prevents the freezing of moisture in the material at low temperatures. Ensure the normal construction of concrete at negative temperature and reduce the freezing point in the concrete mixture.

It can be combined with water reducer, air entraining agent, etc., and the effect is better.

Features: 1.This product is composed of antifreeze, early strength, air entrainment, water reduction and other components.

2.This product does not contain chloride salts, has no rust effect on steel bars, and can be widely used in the winter construction of industrial and civil buildings, roads, bridges and water-type buildings.

3.This product is a gray powder, soluble, non-toxic and easy to use.

(1) When the minimum daily temperature is 5, when the concrete is covered with a layer of plastic film and two layers of straw bags or other substitutes, an early strength agent or an early strength water reducer can be used instead of antifreeze.

2) when the daily minimum temperature is a 59, 10 and a 15, when the above-mentioned thermal insulation measures are still adopted, the antifreeze agent of the specified temperature of a 5, -10 and a 15 can be used respectively. At the same time, it is necessary to implement the freezing provisions of China's current standard GB50204-92.

3) The selected antifreeze must be approved by the construction administrative department at or above the provincial level. Before the application of the antifreeze, the antifreeze shall be simulated according to the technical indicators in the instruction manual to determine the concrete mix ratio and avoid quality problems caused by improper dosage.

When the average daily temperature of concrete is lower than 5 degrees for 5 consecutive days, the concrete enters the winter construction, and antifreeze must be added. It is an admixture that can harden the concrete at negative temperature and achieve the expected performance and sufficient antifreeze strength under the specified curing conditions. It is a substance that prevents the freezing of water in materials at low temperatures.

I haven't been exposed to this thing, but I look at my dad, he started to add antifreeze at minus 1 degree, because zero is a node between freezing and non-icing.

Antifreeze is added to the sub-zero degree.

minus 5 degrees will need to be added.

Antifreeze should not be mixed at minus 45 degrees Celsius and minus 25 degrees Celsius.

The full name of antifreeze should be called antifreeze coolant, which means coolant with antifreeze function. Antifreeze prevents coolant from freezing and cracking radiators and freezing engine blocks or covers when the coolant freezes when parking in the cold winter.

Many people think that antifreeze is only used in winter, but in fact, antifreeze is used all year round.

Antifreeze is a kind of coolant containing special additives, mainly used in liquid-cooled engine cooling system, antifreeze has excellent properties such as antifreeze in winter, boiling in summer, waterproof scale and anti-corrosion throughout the year.

Chemical composition. At present, more than 95% of domestic and foreign water-based antifreeze uses ethylene glycol, and compared with tap water, the most significant feature of ethylene glycol is antifreeze, while water cannot be antifreeze. Secondly, ethylene glycol has a high boiling point, low volatility, moderate viscosity and small change with temperature, and good thermal stability.

Therefore, glycol-based antifreeze is an ideal coolant.

Types of antifreeze.

There are many types of automotive antifreeze, such as calcium chloride (CaCl2) in inorganic matter, methanol (CH3OH) in organic matter, ethanol (C2H5OH, commonly known as alcohol), ethylene glycol (C2H4 (OH)2, commonly known as sweet alcohol), glycerol (C3H5(OH)3, commonly known as glycerin), lubricating oil and sugar, honey, etc., which are common in our daily life, can be used as the mother liquor of antifreeze.

After adding an appropriate amount of pure soft water (water that does not contain or contains a small amount of calcium and magnesium ions, such as distilled water, unpolluted rainwater, snow water, etc., and the total hardness component concentration of its water quality is between 0-30ppm), it can become an antifreeze in the general sense.

Because methanol and ethanol are volatile, they are not suitable for northern vehicles.

General antifreeze of the general type.

can reach -40, and high-quality antifreeze should be able to reach about -60 version, which is an important indicator for calibrating the quality of antifreeze;

The other is the boiling point of antifreeze, the boiling point of water is 100, and the antifreeze should reach at least 108 or more, that is to say, the lower the freezing point, the higher the boiling point, the greater the temperature difference, and the better the quality of the antifreeze.

The general antifreeze is 30 to 35 degrees, and the freezing point should be at least between 10 and 15 after adding water to mix, and the mixed liquid extracted is in the overflow kettle, where it is generally the product of water vapor cooling, and the antifreeze is relatively less, so it will freeze in the refrigerator.

Every product is different, such as Atlan antifreeze, which has -25 and -45

minus 20 degrees [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

No, the freezing point of -25 degrees car antifreeze is -25 degrees, and it may freeze in -35 weather, so it cannot be used.

Since antifreeze is composed of mother liquor and soft water, and there are many types of mother liquor such as tetraglycol. Ethanol, ethylene glycol, glycerol, etc., soft water is water that does not contain or contains a small amount of calcium and magnesium ions, such as distilled water, unpolluted rainwater, snow water, etc.

When using antifreeze in winter, it is necessary to increase the proportion of line fluid in the antifreeze. But it is better not to exceed 60%, after all, the increase in the mother liquor will reduce the cooling effect of the engine.

It depends on the local minimum temperature, if the minimum temperature is minus 10 degrees, it can be used, if the minimum temperature is minus 25 degrees, it is necessary to use minus 35 degrees, otherwise the car may freeze.

You don't need to add water, you can not freeze, and you can buy antifreeze with a freezing point of -20 or even lower when you buy it. Typically, when the ratio of antifreeze to water is 40:60, the boiling point of the coolant is 106 ° C and the freezing point is -26 ° C.

When the ratio is 50:50, the boiling point of the coolant is 108°C and the freezing point is -38°C. Typically, antifreeze needs to be prepared at a temperature of about 5°C lower than the local minimum temperature.

Antifreeze is a liquid that needs to be added to the car every day, which can prevent the car from freezing or even cracking the pipe due to the low temperature in winter, and cooling the working temperature of the engine in the summer, so as not to cause the boil to boil due to too high temperature, or even naturally. Automobile antifreeze has different freezing points, that is, the minimum degree can be without freezing, so it is possible to achieve -20 without freezing.

Antifreeze can only freeze above -35°C, and depending on the level of antifreeze, it can withstand a temperature of about minus 40-60°C, but if the antifreeze is not replaced for a long time and causes deterioration, the temperature will also freeze when the temperature is lower than 0°C.
