The water from an electric kettle is more poisonous than plastic? This is cleaner than mineral water

Nowadays, many households use electric kettles to boil water, which not only saves time, but also is convenient. Now there are many types of electric kettles. If you accidentally buy inferior electric kettles, using such electric kettles to boil water may be more toxic than plastic. What should I do? Don't worry, as long as you do this, you can drink water with confidence in the future, let's take a look.

Take a stainless steel electric kettle as an example. When buying a stainless steel electric kettle, be sure to choose food grade 304 stainless steel. Because the electric kettles on the market are generally made of high manganese steel or 304 stainless steel. However, the high-manganese steel electric kettle will produce heavy metals such as manganese when heated during the boiling process, and long-term drinking will endanger our health. Why choose food grade 304 stainless steel? 304 food grade stainless steel meets national standards, and its lead and chromium content is much lower than ordinary stainless steel. Therefore, when using this electric kettle, heavy metals are difficult to dissolve in the water, so as not to endanger our health. When buying an electric kettle, it is usually marked with 304 food grade stainless steel or the outer shell trademark on its inner wall. If not, do not buy it.

If the electric kettle is not cleaned for a long time, a thick layer of scale will be formed on the inner wall. The composition of this scale is not simple. It not only contains calcium carbonate and other substances, but also contains a mixture of heavy metals, bacteria, and dirt. A little carelessness will cause harm to the human body, so we must regularly remove the scale thoroughly.

This kind of oxide scale is formed by a chemical reaction when certain substances in the water are reheated. These substances are adsorbed on the inner wall of the electric kettle, usually including calcium carbonate, magnesium hydroxide, etc., and precipitate in the kettle for a long time. If it is not cleaned up in time, the water will not be clean. It may also contain some substances harmful to human health.

When using an electric kettle to boil water, please pay attention to not too much water. One is to prevent the hot water from overflowing and scalding the skin after boiling, and the other is to prevent electric leakage accidents caused by water leakage.
