Scale believe everyone not strange, it is also called the thermonatrite, in daily life, many people think that it is the dirt in the water, harmful to human health, even someone said, often drink some scale water prone to lithiasis.
The fact is it true?
What is the scale?
In hot kettle scale is harmful to the body?
In fact, either with the kettle boil water, or use the filter kettle boil water, can form scale, this is mainly related to water quality.
Hard water quality, lack of oxygen in water, water molecule is not stable, the water solubility decrease calcium and magnesium ions, precipitation, form a scale.
Water temperature above 60 ℃, especially in the north of water quality is hard, will produce scale, exist in the daily water bottle and boiler scale, the solution is to regularly clean.
Because the scale is a compound of when boiling water precipitation, main component is calcium carbonate and magnesium carbonate.
This kind of calcium carbonate and magnesium carbonate not harmful, it doesn't matter even if drink into the belly.
Chemical, calcium and magnesium ions of water known as hard water.
Even accidentally drank this hard water or scale, also won't damage your health.
Why doesn't scale?
As mentioned above, the scale is, in fact, some mineral precipitation, mainly composed of calcium carbonate, calcium sulfate, magnesium hydroxide, magnesium carbonate and other insoluble compounds.
Because the calcium and magnesium are essential trace elements in our bodies, many of these trace elements actually very insufficient.
But if you want to make calcium and magnesium, hard water is not desirable.
Drank 1 liter of hard water, after all, but only to add less than 80 mg of calcium, and adults need 800 milligrams of calcium a day.
The disadvantage of hard water according to the chemical point of view, with the increase of PH value, water soluble mineral components, a decrease in the ability of the mineral composition,
Main precipitation of calcium carbonate to form scale.
If there are scale, therefore, is alkaline water, water, minerals, these minerals is harmless to the human body.
But, despite the hard water harmless, hard water is not popular with people.
Hard water taste bad, drink up without the intimacy of the soft water.
Also, the scale is harmless to human body, but very stable chemical properties, will not only affect the heat transfer rate, energy consumption,
1 mm thick scale can take 10% of the energy)
, excessive scale scale may clog pipes, water become smaller, easier to bring safe hidden trouble.
