Is scale harmful to the human body?

Scale exists on many appliances that come into contact with water, such as the surface of containers or pipes. The main components of scale are a large number of heavy metal ions. If the human body consumes water containing scale, calcium and magnesium ions will easily appear in the body. These are important components of stones, so everyone should clean the scale in time to ensure the health of the water quality.

harm

Hard scale is usually cemented to the surface of containers or pipes. First, hard scale has poor thermal conductivity, which will lead to deterioration of heat transfer on the heating surface, thereby wasting fuel or electricity. Secondly, if hard scale is bonded to the inner wall of the water heater or boiler, it will greatly increase the risk of rupture or even explosion of the water heater or boiler due to thermal expansion and contraction and uneven force. Secondly, when hard scale is cemented, a large amount of heavy metal ions are often attached to it. If the container is used to hold drinking water, there is a risk of excessive heavy metal ions dissolving in the drinking water. Therefore, the harm of hard scale is obvious.

Scale fragments enter the stomach and react with hydrochloric acid to release calcium, magnesium ions and carbon dioxide. The former is a necessary substance for the formation of stones. The latter will cause bloating and discomfort, and patients with gastric ulcers may also be at risk of gastric perforation.

Elimination method

① To remove scale by boiling sweet potatoes (sweet potatoes, yams) in a kettle, put more than half a kettle of sweet potatoes, fill it with water, and cook the potatoes. Next time you boil water, scale will not accumulate. But be careful not to scrub the inner wall of the kettle after boiling sweet potatoes, otherwise the descaling effect will be lost. For old kettles that are full of scale, after boiling them once or twice using the above method, not only will the original scale gradually fall off, but it will also prevent scale from accumulating again.

② Use baking soda to remove scale. When boiling water in an aluminum kettle with scale, add 1 teaspoon of baking soda and boil it for a few minutes to remove the scale.

③Boil eggs to remove scale. The scale on the kettle that boils water will become hard and difficult to remove after being used for a long time. If you use it to boil eggs twice, you will get the desired effect.
