Glass water is very important for the clarity of the windshield. With so long glass water, do you know why the car glass water is blue?
Classification of automotive glass water
The glass water in the market can be generally divided into three categories, one is special for summer, and the ingredients of the shellac are added to it to remove the fly residue that hits the glass; the other is special for winter, ensuring the temperature. At less than 20 degrees, it will not freeze and freeze the car-related equipment; the first type is the special-effect anti-freeze type, which can not freeze at minus 40 degrees and is used in extremely cold regions.
Why are the three types of glass water blue?
Because there are many chemical additives in the glass water, it is toxic to the human body. The manufacturer prepares the glass water as blue to remind people of its toxicity. At the same time, this color can be conveniently separated from other liquids to avoid adding errors.
What is the car glass water formula?
Beimai Auto Parts Network said that the glass water formula is generally water, alcohol, corrosion inhibitor, ethylene glycol and a variety of surfactants, etc., its scientific name is automotive windshield glass water.
The six major effects of automotive glass water
1, cleaning effect. Due to the action of surfactants and additives, the glass water can be wetted, infiltrated, etc., thereby decontaminating and cleaning the glass.
2, antifreeze effect. The addition of alcohol and ethylene glycol makes the freezing point of the liquid significantly lower, which not only prevents freezing, but also dissolves the frost faster.
3. Anti-fog effect. These chemicals form a monomolecular protective layer on the windshield surface to prevent the formation of droplets and ensure the clarity of the glass.
4, antistatic effect. It can adsorb substances on the surface of the glass, remove the charge on the surface, and play an antistatic role.
5. Lubrication. The viscosity of ethylene glycol is large, which can lubricate the friction between the wiper and the glass to avoid scratches.
6, anti-corrosion effect. Due to the addition of multiple corrosion inhibitors, the glass water does not corrode other metal parts of the car.
Misunderstanding of homemade car glass water
Some car owners often prefer to use homemade glass water such as detergents and washing powders, and many owners use water to replace glass water. I do not know that there are certain hidden dangers in both practices. Because the various detergents are alkaline, they have a strong corrosive effect on the rubber, and also accelerate the hardening of the wiper strip, causing the windshield to be scratched. Adding clean water is very easy due to the poor lubricity of the water, and it is easy to make the strip scratch the glass.
