Annex: Anti-freeze solution and its application guide
Currently, water is widely adopted as the cold-medium of the water-cooled engine,
including hard water and soft water. River water, well water, spring...etc. enrich water
with the mineral material as hard water, being subjected to hot empress the mineral
quality sink wall to become water dirt in water set with spread the hot machine, dying
down diesel engine to spread thermal energy dint, the serious hour will appear an urn of
set and live cold wreath to chafe, the piston choked to death. But the water tank knot
dirt hereafter will cause the water temperature go up and open a pot.
Therefore must use the soft water as the anti-freeze. The in common solu
tion of transferring the hard water into soft water is to boil hard water to r
emoves sediments. The more exhaustive method is to add to soften in the hard
water, such as adding 0.5 baking sodas of

There is much weakness using the water as the anti-freeze.1)it is easy to be

As having been overcome many disadvantages of the water-coolant, the anti-freeze
solution becomes the ideal coolant which can be used in each season of the year.
1. What is anti-freeze solution?
Anti-freeze solution is a coolant used in winter to prevent frostbite. It has a long history.
At the first, people added the inorganic salts into the water to lower the freezing point or
raise the boiling point; then the organic alcohols (such as ethanol, methanol, etc) were
added further. And in the recent years, the anti-freeze solution has developed to become
the glycol and glycerol based anti-freeze solutions. But for the price reason, the
