Advice 1: How to make antifreeze

In English the word "antifreeze" – "ice-free". That is, the coolant for operating engines in low temperature conditions. To make antifreeze – so, using certain additives to lower the freezing point of the coolant.
How to make antifreeze
You will need
  • Concentrate antifreeze (coolant)
Instruction
1
To lower the freezing point of the coolant in the cooling system of your car, add the water, such as alcohol. Or glycerin, also contributing to the lowering of the temperature, at which the crystallization water molecules. But such simple formulations of antifreeze coolant today can't solve all the challenges facing modern antifreezeAMI. So in order to make antifreeze, get the concentrate antifreezeand shop and cook following the enclosed instructions.
2
Modern brand antifreezes for vehicles with internal combustion engines based on ethylene glycol. Ethylene glycol is the representative polyhydric alcohols. The purified form is a slightly oily, colorless, transparent, odorless liquid. Tastes sweet and is very toxic. The penetration of the glycol into the person may end in death.
3
In addition to the ethylene glycol in water to produce a high-quality coolant additives are added, which give the antifreezehave anticorrosion properties. For this reason, leave the antifreeze in the cooling system in the warmer time of the year. Moreover, the ethylene glycol increases the boiling point of your coolant, and it is important in hot summer.
4
Another important property acquires the coolant additives – anticavitation. Cavitation is the formation and bursting of vapor bubbles in the liquid when boiled. This process gradually destroys the metal, carving out the surface of the microparticles and forming ulcers that are easier then corrode. Ulcers grow in the shell. Also additives impart anti-foaming properties.
Note
The color of the coolant has nothing to do with the essential characteristics of antifreeze and does not reflect its quality.

Advice 2: How to make ferromagnetic liquid

Experiments with ferromagnetic fluid are widely distributed in the form of videos on the Internet. The fact that this kind of liquid under the action of the magnet performs a certain movement that makes the experiments very entertaining. Let's try to do this stuff yourself. But first, find out what it is.
How to make ferromagnetic liquid
Instruction
1
Ferromagnetic fluid can be made with your own hands at home. To do this, take the oil (motor, sunflower and other), and toner for laser printer (substance in powder form). Now mix both ingredients until the consistency of sour cream.
2
In order for the best effect, warm the mixture on water bath for about half an hour, do not forget to stir.
3
Remember that a strong magnetization has not every toner, and therefore try to choose the most quality.
4
Ferromagnetic liquid (ferrofluid) is a liquid which is highly polarized under the influence of a magnetic field. Simply put, if you bring an ordinary magnet to this liquid, it produces certain movements, for example, becomes something like a hedgehog, gets the hump, etc.
5
In General, ferrofluid is a colloidal system, which consist of ferromagnetic or ferrimagnetic particles of nanometer size. These particles are suspended in fluid (liquid – usually water or organic solvent).
6
To create a resistance similar fluid, to bind ferromagnetic particles with a surfactant (surface active substance) - it creates a so-called protective shell around the particles, which prevents them from sticking together due to van der Waals or magnetic forces.
7
However, despite its name, ferrofluids do not have ferromagnetic properties. This is because once the external magnetic field disappears, they do not retain residual magnetization.
8
Ferrofluid is essentially a paramagnetic, they are also often referred to as "superparamagnetism" because they have very high magnetic susceptibility.

Advice 3: Can I mix antifreeze with antifreeze?

Antifreeze and antifreeze - means for cooling automobile engines. Some motorists do not see them as a fundamental difference, others doubt the quality of the good old antifreeze, and the third one safely mix these liquids.
Can I mix antifreeze with antifreeze?

Protivozmeinaya fluid (antifreeze)



If the coolant in the jacket of the engine flooded with water, in case of leaving her in the cold, resulting ice expands and will damage the internal parts, if not break the body of the shirt. Special coolants for vehicles to prevent damage to your items, because they have a lower freezing point and, moreover, during crystallization of the antifreeze turns into a mushy mass, which is not able to bring harm to the parts. Crystallizes, antifreeze lose fluidity, and therefore is no longer able to fulfill its mission.

Antifreeze, used as coolants for vehicles, created on the basis of ethylene glycol, diluted with water, with the addition of various additives. The latter are intended to give the solution additional properties: anti-corrosion, anti-cavitation agent, anti-foaming and fluorescence (staining).

Antifreeze – antifreeze is also



It so happened that we all were forced to participate involuntarily in this paradox of the Russian language. Probably, many not often heard such a dialogue:
- You have antifreeze poured?
- No, I have not antifreeze. I have antifreeze.
ANTIFREEZE acronym stands for: technology of organic synthesis of OL (i.e., alcohol).


The common name "antifreeze" became its own, although within this the names of a number of different grades, denoted by Latin letters and numbers. This was originally the proper name noun "antifreeze" became a household word. Meanwhile, the word "antifreeze" is a General name for all non-freezing liquids. It translates as "non-freezing, anti-freeze".

Can you mix different brands of antifreeze



"Can you mix antifreeze with antifreeze?" – this is often how the question motorists, without going into the variety of both. As mentioned, different brands of antifreeze contain different additive package, sometimes conflicting with each other. The result is that it can precipitate and clog the system.
If you still had the trip to mix different coolant on arrival at the garage thoroughly rinse the cooling system with distilled water. The same must be done when moving from one antifreeze to another.


Based on the foregoing, it is better not to mix fluids, especially if they have different distinctive colors. First of all, it just refers to domestic green antifreeze and foreign antifreeze, which often red.
