Why can t the water heater for the kettle scrape the rust

Rust such as rapid heating is formed by the calcification of minerals in the water, and the damage is relatively large if it is scraped.

It is recommended to use the following method:

1. Wrap a small ball of absorbent cotton with gauze, or use a piece of peeled, seeded, and washed coarse loofah pulp, and put it in the kettle when boiling water, the water alkali will be adsorbed on the cotton ball or enter the loofah pulp, and the bottom of the pot and the wall of the pot will be less scaling; After using it for a period of time, there is more water alkali in the cotton ball and loofah, which can be taken out and washed off with water before being used or replaced with a new one in due course. The easiest way to do this is to use water purification facilities at home.

2. [Recommended] Use a small amount of dilute sulfuric acid to acidify the scale in the pot several times, so that the pot scale is eroded, and then rinse the residual acid with clean water. When using pickling, the amount should be less and the concentration should be dilute (about 30%); Also pay attention to safety to prevent acid from touching the body with clothing and corroding the kettle. Note: If you are at home, you can use white vinegar, rice vinegar, baking soda, etc.

3. Put apples and hawthorns into the scaled kettle, plug the lid and spout tightly, and leave it for about 10 days, and the water alkali in the kettle is soft and easy to remove; If you cut the apple peel and hawthorn, add water and boil for an hour or two, the descaling effect is faster. After putting some potatoes in the pot and boiling for a few hours, the limescale will crack and fall off.

Of course, you can't scrape, the kettle is mainly kept warm by the inner tank silver mirror, and the silver mirror may be damaged if you scrape; The main ingredient of water embroidery is calcium carbonate, you can try to bubble with hot vinegar, but the time is not too long, ten minutes or so.

I think there is a layer of anti-rust film on the surface of the water heater, and it is easy to scrape off when you scratch the rust, and the more you scrape, the longer the rust, so you can't scrape.

The hot water boiled out after the kettle rusts will contain rust, which is harmful to the human body, its main component is magnetic copper carbonate, and the human body will have symptoms of nausea and vomiting if it is ingested more, and even shock will occur in severe cases.

The general methods of removing rust are: soak the rusty kettle in rice washing water for several hours, and then wash it with clean water; You can also scrub it with baking soda and rinse it off with clean water.

In addition, the kettle will also produce scale after a long time, containing a variety of heavy metal substances, if long-term drinking will lead to human digestive and urinary system problems, nervous system disorders, affecting people's health.

Limescale is the water containing calcium sulfate slightly soluble in water after the container has been burned many times, and the calcium bicarbonate and magnesium bicarbonate that were originally dissolved will decompose in the boiling water, and release carbon dioxide, generating insoluble calcium carbonate and magnesium hydroxide to precipitate.

There are many hazards of scale, such as scale fragments into the stomach, will react with hydrochloric acid to release calcium and magnesium ions and carbon dioxide, the former is a necessary substance for the formation of stones, the latter will make people flatulent, uncomfortable, gastric ulcer patients may also have the risk of gastric perforation.

Therefore, the hot water kettle at home must be cleaned up in time after the scale, the methods of removing scale are: slice the potatoes, put them in the kettle and boil, then the potatoes will sink to the bottom of the kettle together with the scale around the kettle; Dilute the white vinegar or other vinegar with water, pour it into the kettle, put it on the fire and boil for 2 hours, pay attention to the full contact between the solution and the inside of the kettle to remove the scale more effectively; Put the empty kettle on the stove to boil the water in the scale, remove the kettle when there is a crack at the bottom of the kettle, quickly inject cold water, or wrap the handle and spout with a rag, hold it with both hands, quickly sit the boiled kettle in cold water, repeat 2 to 3 times, the scale at the bottom of the kettle will fall off due to thermal expansion and cold contraction.

It should be noted that it is best to use food-grade descalers to remove scale from water appliances, because industrial-grade descalers contain impurities and even poisonous, and drinking them is harmful to the human body; It is not advisable to use strong acids to remove scale, because strong acids are corrosive and harmful to household appliances and the human body.

When the kettle rusts, we will definitely worry about whether it will have an impact or even create a safety hazard. But in fact, the kettle will not lose its efficacy due to the early rust of the front group, and will not cause direct harm to the human body.

The rust of the kettle is caused by the prolonged exposure of the metal inside to water and air. This does not affect the thermal performance of the kettle, but if it is used for too long and there is too much rust inside, it may affect the quality and taste of the hot water. At this time, we can try to use some detergent to clean the inside to remove the rust and make it tidy again.

Or just swap out a new kettle.

In fact, rust is not only a problem for hot water bottles, but also common in refrigerators, faucets, pots, etc. Proper use and care can slow down the rate of rusting. In addition, we can also choose to buy materials that are not easy to rust and make them, such as stainless steel, aluminum alloy, etc.

In daily use, we also need to pay attention to keeping drinking water clean and hygienic to avoid water pollution. In addition, regular cleaning of the kettle can remove build-ups, prevent bacterial growth, and prolong the life of the appliance.

In short, rusting the kettle will not affect its use, but keeping the utensil dry and clean, and trying to avoid rust will have a better maintenance effect. If there is too much rust, try cleaning it with a detergent or replacing it with a new appliance to keep the water pure. <>

The rust inside the kettle is actually caused by the accumulation of calcium carbonate deposits on the inner wall of the kettle. Because the water contains a small amount of calcium ions, calcium carbonate will be formed during the heating process, which will gradually precipitate on the inner wall of the kettle. To get rid of this calcium carbonate, you can heat up an appropriate amount of white vinegar and pour it into a warm pot.

Then close the lid and shake the kettle constantly, as the calcium carbonate will dissolve in the vinegar. As long as you use enough vinegar, the limescale will all be dissolved.
