And scale is insoluble in water, which is only relative. After the water is heated, part of the precipitate will dissolve, thus bringing the heavy metal ions that form the precipitate back to the water, which makes the content of heavy metal ions in the water exceed the requirements of sanitary standards and is harmful to human health. For example, calcium carbonate and magnesium carbonate are easy to form stones when deposited in large quantities in the human body.

Some ways to reduce the scale:
1, a water softener for removing calcium and magnesium from water.
In some large appliance shopping centers, you can usually see some water softeners. The principle is to replace calcium and magnesium in water with salt. This water purifier has two disadvantages. One is not conducive to environmental protection, so that a large amount of sodium is discharged into the environment. More importantly, high sodium water is easy to cause cardiovascular and cerebrovascular diseases, and it can be felt by some people with poor kidney and lung function and some people with sensitive taste.
2. Put some rough substances in the kettle.
Because magnesium calcium carbonate is easy to deposit on some rough objects in water, some consumers can put towel gourd tendons and gauze in a pot of boiling water and replace them after a while.
3. After the water is boiled, let it settle before drinking. After the water is boiled, do not pour it into the container immediately, and then pour it after a little precipitation. In addition, clean the remaining water in the container and clean the inner wall of the kettle in time.
