How to choose non-freezing liquid

With the onset of the autumn-winter period, motorists prepare their car to the inevitable slush, dirt, frozen. How to choose a high-quality and safe health of non-freezing liquid? Guided by several mandatory rules, this is easy.

First of all, it is necessary to pay attention to the fact that the non-freezing fluid is spilled, in the people - non-freezing. Canister or other packaging should be transparent, with well-spinning high-quality lids. Antifreeze in such packages will cost somewhat more expensive than in PET bottles. But it is possible to avoid the possibility to buy a fake, which is often distinguished in such a container.

You should pay attention to the label. It should not be damaged, good quality, contain complete information about the composition of the liquid, freezing temperature, about precautions and the manufacturer of this antifreeze.

Good non-freeze does not have a precipitate on the bottom of the bottle, if you look at her lumen. In addition, if you slightly shake the canister, a steady foam should appear on the surface of the fluid. This suggests that there are surfactants (surfactants), which are responsible for the purity of glasses.

The non-freezing fluid is made on the basis of alcohol. This may be methyl, ethyl or isopropyl alcohol. The cheapest and efficient methyl alcohol for the manufacture of antifreeze was prohibited, since doctors revealed irreparable harm to health during the evaporation of methanol. However, this does not interfere with it in underground production. Methyl alcohol does not smell and freezes at low temperatures. Ethyl alcohol based liquid also does not have odor and is not harmful to health, but its value significantly exceeds the cost of the rest. Mostly in the industry uses isopropyl alcohol. With its cheapness and relatively neutral impact on the human body, this alcohol is distinguished by a sharp unpleasant odor. To eliminate such a smell, manufacturers add various flavors.

A good antifreeze does not freeze (for this it is intended) if it is in the freezer at a temperature of 15 ° to 25 ° as an experiment at a temperature of 15 ° to 25 °. Liquid only gradually thick. With large frosts, it is recommended to use isopropyl concentrate. Only in no case cannot be poured it in its pure form, it is necessary to dilute, according to the instructions.

If weakness occurs when the wiper operation occurs, the headache, scattered attention, you must stop the car and breathe fresh air, and at the first opportunity to change the non-freezing fluid. During glasses, it is recommended to include air recirculation in the cabin.
