How to prepare antifreeze, how to formulate antifreeze

You can't match it yourself, if you can match it yourself, it's also very troublesome, it's better to buy the finished product. 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. 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. Many drivers are generally accustomed to using antifreeze in winter and switching to tap water in summer, thinking that this is more economical and cost-effective, but in fact, it is not.

Preventing freezing, preventing the cylinder and radiator from freezing and cracking are only the most basic functions of antifreeze, and antifreeze also has other important functions, such as anti-boiling, anti-scale, anti-corrosion, etc. The use of antifreeze in summer can effectively prevent the water tank from "boiling", and the use of antifreeze throughout the year can prevent scale formation in the water cooling system and inhibit the corrosion of various metals. Usually drivers ignore the harm of "scale", in fact, the harm of scale to the car is quite large, the thermal conductivity of scale is very small, is 1 25 of cast iron, 1 50 of brass.

With scale, the thermal conductivity of the coolant is greatly reduced, the engine temperature rises, and the corrosion is aggravated, which promotes the increase of scale, forming a vicious circle, and the scale may also block the pipeline of the cooling system, causing greater accidents, according to the relevant domestic data reports, in the maintenance work of the normal use of the automobile engine, 6% is the engine cooling system failure, and the main reason for the failure is the scale and metal parts are corroded, which shows how harmful the scale and metal parts corrosion is to the engine water cooling systemTherefore, the use of high-quality antifreeze all year round can not only effectively protect the car's water cooling system, but also effectively save money.

Hello, the antifreeze can not be configured by yourself, you have to buy the same model as the original car.

Summary. Hello dear, the formula of antifreeze is: ethylene glycol + distilled water + additives (malonic acid, anti-corrosion and anti-scale essence and triethanolamine) mixed, this is the commonly used ethylene glycol water-based antifreeze, winter can be anti-freezing, summer can be anti-boiling, perennial use, and can also prevent corrosion and scale.

<> formulation of antifreeze.

Hello dear, the formula of the antifreeze is: ethylene glycol + distilled water + additives (propionic acid, anti-corrosion and anti-scale essence and triethanolamine) mixed, which is commonly used ethylene glycol water-based antifreeze, which can be anti-freezing in winter and boiling in summer, and can be used all year round, and can also prevent corrosion and scale. <>

<> data development: 1. When the number of stops in the cold winter, prevent the coolant from dissipating and freezing the radiator and freezing the engine cylinder block or cover, and when the temperature is high in summer, it can effectively prevent boiling and avoid the appearance of boiling and rushing rocks. Automobile antifreeze has a great effect, which directly affects the energy and service life of the car.

Many people think that antifreeze is only used in winter, but in fact, antifreeze is used all year round. 2. Antifreeze also has anti-corrosion function. Because the cooling system of the engine includes steel, aluminum alloy, cast iron, copper and solder used in the welding of the water tank, the cylinder block and cylinder head are generally made of cast aluminum or cast iron, the water tank is mainly made of copper and Huang copper, antifreeze is in contact with these metals for a long time, must be able to protect all these metals, the use of deionized water and appropriate additives can prevent the emergence of various corrosion.

<> recipe. Hello dear, the formula of antifreeze is: ethylene glycol + distilled water amusement + additives (malonic acid, anti-corrosion and anti-blocking sulfur and triethanolamine) are mixed. <>

First open the liquid filling port, then open the drain valve, drain the antifreeze, then add antifreeze, wait until the drain valve begins to flow out of new antifreeze and then tighten it, when the antifreeze kettle is added to the scale mark, start the engine, the antifreeze liquid level will slowly drop, and continue to add until it is stable. The next day, just check and continue to the tick mark.

Common methods, 1, first open the liquid filling port and then open the drain valve, (generally under the water tank) drain the antifreeze, then add antifreeze, wait until the drain valve begins to flow out of new antifreeze and then tighten, the antifreeze kettle is added to the scale mark when the engine is started, the antifreeze liquid level will slowly drop, you keep adding until it is stable, check the next day and then continue to the scale mark. 2. Circulation method professionals to do, the return pipe is disassembled, the kettle is added, the engine is started, and the old antifreeze is circulated with new antifreeze until the new antifreeze flows out of the return pipe, and the color can be seen wide side fingers.

To judge when to change the coolant, the first way is to look at the instructions for the use of coolant, and there will be a description of its products; Generally, the coolant is added to the water tank, and its service life is less than 2 years. Second, you can also operate it yourself, open the water tank, check the turbidity of the liquid in the box, if it is already very turbid, and there are floating objects that are corroded by the metal of the box, it is recommended to change it. Third, the refrigerant is lower than the liquid level.

Antifreeze can be added like this:

Open the engine cover, look for the antifreeze kettle, some cars have two antifreeze pots, one is to exhaust heat for the transmission, the other is to exhaust heat for the car engine, generally the antifreeze kettle is all spherical, also called expansion kettle, open the teapot lid, pour the car antifreeze into the antifreeze kettle.

When adding antifreeze, you must pay attention to the amount of added should not be too much, generally there is a water mark on the pot, if not, add it to the center line of the pot a little above.

Different well-known brands and different colors of antifreeze do not need to be mixed, the secret recipe is likely to be different, and mixing is likely to cause chemical changes, resulting in the loss of antifreeze properties. It is also not necessary to mix with water, the ice content of the water is low, and it has residue, which will produce dirt and cause blockage over time.

The role of antifreeze:

Antifreeze. When the temperature is relatively low, ordinary water is particularly easy to freeze, and it is easy to cool down and break the pipe after freezing, but after adding antifreeze, it can be kept at minus 40 degrees Celsius without freezing, so in the cold winter, the engine can be started normally.

Antisepsis. Antifreeze is also a liquid with special additives that prevent corrosion of the cooling system and remove rust.

Cooling. Car antifreeze also has the function of coolant, which can help the engine cool down and dissipate 60% of the heat of the engine.

Anti-scale. There are many heat dissipation tanks in the car cooling system, and it is easy to form scale when adding water and high temperature, but antifreeze is deionized water that has passed the softening treatment, so it can play a role in antiscaling.

Anti-boiling. The boiling point of antifreeze is generally 106, and the normal temperature of the engine should be kept at 90, so by adding antifreeze, even if the vehicle is running for a long time, it can also play an anti-boiling role.
