50
100 times less corrosive to metal compared with water.
2. Anti cavitations
Cavitations are formed by numerous foams impinging the metal. Tests show that hard
waters containing salts and bases are several dozens faster in its cavitations speed
compared with that of clean soft water. While anti-freeze solution does not contain hard
water, and the anti-foaming in it can inhibit the production of foams.
3.
High boiling point character
The boiling point of anti-freeze solution is usually at 105
℃
~110
℃
, even higher than that
of water.
4. Anti-scaling character
High quality anti-freeze solution is made from the distilled water and it contains
anti-scaling agent, hence it does not produce any scale.
It has the following characters:
1) Superior anti-freeze performance
2) Anti-corrosion and anti-rust
3) Non-swelling or erosion on the rubber seal guide.
4)Preventing scaling of the cooling system.
5)Anti-foaming.
6)Low viscosity at low temperature.
7)Stable chemical properties.
III. How to select and correctly use anti-freeze solution
At present, anti-freeze solution is widely used, inadequate understanding of the
characteristics, requirement and method in its use will bring some trouble to your vehicle,
such as starting difficulty, leakage at pipe fittings, hose rupture, watering difficulty,
radiator corrosion, cylinder sleeve cavitations, etc.
