The hardness of water has a very good advantage: as we all know, minerals are indispensable elements for the human body, and the development and growth of the human body cannot be separated from minerals, so minerals can be supplemented from daily drinking water. If the hardness of daily drinking water is reduced, it will inevitably reduce the mineral content and lose many minerals beneficial to the human body.
But in fact, there are ten disadvantages of too high hardness:
If the hardness in the water is too high, it will seriously affect us. For example, hard water can precipitate soap and wash clothes. The main principle is that the main component in soap is sodium stearate, which can react with calcium and magnesium ions to make calcium/magnesium stearate invalid.
② Too high hardness will also cause the kettle to scale when we boil water, which will affect the health of the door. The main reason for the formation of scale is that water will heat up and the oxygen content will decrease when heated. At this time, the solubility of calcium and magnesium ions in water will decrease, and calcium and magnesium ions will precipitate on the kettle to form scale.
(3) In industrial production, the influence of scale is more serious. In the boiler, scale will block the pipeline and cause explosion due to excessive pressure in the boiler. Therefore, in industrial production, boiler make-up water will be filtered, and hardness is an important detection index.
