Antifreeze red and its other types

Antifreeze is a liquid in which the freezing point is much lower than the crystallization temperature of water. The use of this liquid helps prevent damage to the mechanisms that may occur during the crystallization of H2O. Antifreeze (red, yellow, green and others) consists of water and polyhydric alcohol. In addition, all kinds of additives, anticorrosive components are added to the coolant. These additional connections help protect parts. In the composition of liquids are also dyes, giving them a particular color. According to the comments of experts, the color of the liquid does not affect its performance. In accordance with the field of application, antifreeze (red and other types thereof) may contain propylene glycol or ethylene glycol.

The latter is a viscous, oily, colorless liquid. It has a characteristic faint smell. Ethylene glycol is a strong poison, so care should be taken when handling it. Pure ethylene glycol freezes at a temperature of minus thirteen degrees. The temperature of its boiling is +197 degrees. It should be noted that the concentrated ethylene glycol in the aqueous solution freezes at lower temperatures (if two parts of ethylene glycol and one part of water are used). The boiling point of the antifreeze is on the average about one hundred and twenty degrees, and the minimum freezing temperature can be equal to seventy degrees below zero. As a rule, antifreeze (red, yellow and others) contains about 50-60% of ethylene glycol. In this case, its minimum freezing point is thirty degrees below zero.

When making antifreezes, propylene glycol is also often used. This material is more ecological. At the same time, the performance characteristics are practically independent of the substrate. However, propylene glycol is safer and less toxic.

The word "antifreeze" can literally be translated as "against frost" or "unfrozen". This term is used to refer to all grades of coolant.

Tosol or antifreeze - what is better?

It should be noted to begin with that the first concept is used to refer to domestic cooling fluids. The term "tosol" contains the name of the department in which it was developed (Department of Technology of Organic Synthesis (TOC)). The end of "-ol" indicates that the material belongs to alcohols. Tosol refers to traditional cooling fluids, which have recently been used less and less.

As already noted, the performance properties of the material do not depend on exactly which antifreeze - red, blue, yellow or even some other color. Initially, all liquids are produced in the same color. The dye adds antifreeze only a certain "individuality". There is an opinion that mixing of cooling liquids of the same color with each other is allowed. It should be noted that in many respects it is a delusion. On the package with antifreeze, the manufacturer always gives an instruction with indication of the possibilities of mixing this type with the others.

At one time, a certain state standard was developed for domestic cooling liquids. It is necessary, however, to note that absolute compliance with GOST does not guarantee their high quality characteristics at all. For example, Russian-made antifreezes are not always applicable to modern engine designs. At the same time, European antifreezes that do not meet the Russian standard show high quality indicators.
