What should I do if there is limescale in boiled boiled water?

Put leftover rice soup or noodle soup in a pot full of limescale, the thicker the better, and after a few days, the scale in the pot will slowly fall off after it has naturally fermented and become sour. The longer it is placed, the better the descaling effect will be.

Limescale remover.

Scale remover is a special effect remover specially used for removing scale produced by Chengdu Hengfeng Hongye Detergent Factory, which has the following characteristics:

1. Completely dissolve the scale formed by water-related appliances such as kettles, pots, boilers, rice cookers, bathroom showers, faucets, toilet scales, tank scales, thermoses, solar water heaters, water heaters, washing machine liner scale, etc.

2. How to use: dissolve 1-10% scale remover with water and pour it into a container with scale, just flood the scale, and rinse it with water after all the scale is dissolved.

Three methods for removing scale from hot water bottles.

1. You can pour some hot vinegar into the bottle, close the lid tightly, shake it gently, leave it for half an hour, and then wash it with water to remove the scale.

2. Add 50 grams of baking soda and a cup of water to the bottle, close the lid tightly, shake it gently, leave it for half an hour, and then wash it with water.

3. Break the egg shell and put it in a water bottle, pour a few drops of detergent and an appropriate amount of water, after capping, shake it up and down, and finally rinse it with water.

China's drinking water standards are 20 years behind those of developed countries. In the past 30 years, industrial and agricultural pollution has become increasingly serious. Therefore, today's boiled water is no longer the boiled water of a few decades ago when industry and agriculture were less polluted.

After the water is boiled: 1) the beneficial dissolved oxygen is transpired, the watering flowers are withered, the fish are not alive, and it is not conducive to the metabolism of the human body; 2) It destroys the hexagonal annular structure with the most affinity between water molecules and human cells, which is not conducive to absorption; 3) Although the bacteria have been killed, they still remain in the water, which is an allergenic substance - a source of pyrogen, causing headaches, low-grade fever, allergies, arthritis, etc.; 4) The concentration, pathogenicity, carcinogenicity and mutagenicity of the carcinogen chloroform, metals, heavy metals, nitrites, pesticides, detergents, etc., which are also increased with the concentration of boiling water, after the residual chlorine in tap water reacts with putrescine. Therefore, this kind of boiled water is collectively referred to as "pathogenic water", "stagnant water" and "carcinogenic water" in the world.

Experts have determined that in the suspension, sedimentation and unpreventable scale in the thermos bottle that has been used for a month, there are milligrams of trace elements such as heavy metals lead, cadmium, heavy metals arsenic, and mercury that can be dissolved in water again and are harmful to the human body. If it is not removed in time, it is repeatedly used to boil water and fill water, and it accumulates too much in the body, which will cause chronic poisoning, and even carcinogenic, teratogenic, etc., and drinking ordinary boiled water in pots and bowls, water dispensers, and water boilers all year round is no exception!

The water residue is all in the kettle, soak the bottom of the kettle with vinegar to remove the white scale, and then pour it into the water bottle every few minutes after the water is boiled, and the problem is solved. (Also, wash the kettle every other week.) ）

Are there minerals and trace elements in tap water? There will be scale, unless you use pure water to boil, so there must be no, it is unhealthy, my kettle has been boiled with pure water for two years, there is no scale, but the kettle is stainless steel.

1. First, add a spoonful of salt to the kettle you are using.

2. Then add water to the pot to dissolve the solubility of salt.

3. Then turn the pot on and bring the water to a boil.

4. Wait until the pot of water boils and pour out the water.

5. Then add water to the pot again, and then use this pot to boil water, and then there will be no water scale.

6. After boiling, you can drink it directly, and there will be no more limescale.

Hello: 1, it is impossible to boil water without scale, we can take measures to reduce scale.

2. (New pot) After boiling water each time, pour out the boiling waterImmediatelyFlush in a little cold water, the effect of thermal expansion and cold contraction, the scale generated in the initial stage will fall off, just pour it out, stick to it, the generation of scale is the lowest level.

How to boil water without producing scale, purified water Boiling water does not produce scale.

Since water contains minerals such as CaO, MGO, etc., it reacts with the water in the heating composition to form precipitates such as Ca(OH)2 and Mg(OH)2, and a large amount of sediment is formed when it is aggregated. If these minerals are filtered out, limescale will not be formed. But at the same time, some nutrients are lost in the water due to filtration.

1. When the tap water is heated to 80 degrees, the calcium and magnesium ions in the water will form scale.

2. Causes of scale: tap water contains more Ca2+, Mg2+, 2HCO3-=CO32-+H2O+CO2, Ca2+CO32-=CaCO3, Mg2++2OH-=MG(OH)2, the solubility of these two substances in water is very small, so the precipitation is formed.

3. Prevention and treatment methods: the internal cause of scale is the quality of tap water, as long as the temperature exceeds 60 degrees, scale will be generated. Family life tips can be removed with baking soda, acetic acid, citric acid, eggs and potato chips.

Of course, if you want to achieve a better effect, you can install a drinking water anti-scale device on the tap that specifically removes limescale, so that the water coming out of the anti-scaling device will not be formed when it is reheated.

The production of limescale is water bai

Physical phenomena after boiling. After the water is boiled, calcium sulfur containing slightly soluble in water will be precipitated due to the evaporation of the backwater, and the carbonate in the water will be combined with calcium and magnesium ions to form calcium carbonate and magnesium carbonate that are insoluble in water, that is, water alkali. With the continuous evaporation and concentration of water, the water alkali content continues to increase, and scale is formed after reaching saturation.

Scale is harmless to the human body, but it is the natural enemy of boilers and other equipment, which not only increases the cost of boiling water, but also increases the risk of boiler equipment bursting. Every time you boil water and order one or two drops of white vinegar in life, there is no sour taste when you drink it, and it will not scale; Or throw a piece of gauze when boiling water, and the scale will be deposited on the gauze, and there will be no scale in the water.

Do you mean that there will be a gutter when the water is boiled cold, and the answer is that there will be almost none.

In daily life, the inner wall of the kettle will be scaled after a long time, which is related to the hardness of the water. Mainly calcium bicarbonate [Ca(HCO3)2] and magnesium bicarbonate [mg(HCO3)2] dissolved in water, during the boiling process, they will become calcium carbonate [CaCO3] and magnesium hydroxide [mg(OH)2], which are insoluble in water, so that scale is formed. Limescale attached to the inner wall of the kettle will affect the thermal conductivity of the kettle wall, resulting in waste of energy.

China's "Sanitary Standard for Drinking Water" (GB5749-85) stipulates that the index value is: 450mg L.

The softness and hardness of water depend on the content of soluble calcium and magnesium compounds, and the World Health Organization (WHO) classifies the hardness of water according to the standard of "the quality of calcium ions and magnesium ions in 1L of water"; The higher the calcium and magnesium ion content, the higher the hardness of the water.

For drinking water, the hardness will affect the taste of the water, generally water with low hardness feels soft, and water with high hardness feels refreshing and heavy.

Some people think that drinking water with more limescale will increase the risk of stone disease and other diseases, experts said: the generation of limescale is a physical phenomenon after the water is boiled, and stone disease is a physiological phenomenon of the human body, "these two are not the same thing".

Some people like to use a kettle to boil water, which can achieve the effect of high temperature sterilization, but they find that after each boiling water, there is always a layer of white dirt left in the kettle, and a layer will be left after boiling the water once, so they will wonder if there is a problem with the tap water, or the kettle is faulty? Does limescale mean that the water is dirty?

Article **1 In fact, the main component of this layer of white scale is carbonate, and the reason why a layer of white scale is formed is because the content of calcium ions and magnesium ions in tap water is too high, that is, the hardness of water is too high.

The ** of tap water is generally taken from natural water, water contains a large number of natural minerals, but also rich in a lot of ionic substances, under the action of high temperature, calcium and magnesium ions and hydroxide ions in the water combine to form a white precipitate, chemically called magnesium carbonate and calcium carbonate.

Article**2So, is it because the water is so dirty that it contains this substance?

No, no matter what kind of water it is, it contains a certain amount of calcium and magnesium ions, which cannot be removed, and there will always be more or less white precipitate in heating, which does not prove that the water is polluted, nor does it mean that the water is very dirty, after the pure water is filtered, the ions will become very few, and there will be no precipitate when burned.

There is a lot of limescale in boiled water, which will not affect health!

These white sediments are not harmful to health. Calcium and magnesium ions are essential minerals for the human body, which can effectively promote the body's metabolism, and most people's calcium and magnesium intake is low, so drinking this water (hard water) in daily life can also replenish some minerals.

Article**3 So can you drink this water directly with magnesium and calcium?

A large number of components in white scale are calcium carbonate and magnesium carbonate, and the calcium ions in them can play a role in calcium supplementation. The role of magnesium ions is also very strong, magnesium is a necessary substance for many cells in the body to react, if there is a sufficient amount of magnesium ions, the probability of heart disease in the body will be greatly reduced.

You can use vinegar + baking soda, lemon or starch to remove limescale.

1. Edible vinegar + baking soda to remove scale.

Add an appropriate amount of baking soda to the kettle, and then pour a small amount of white vinegar, and white foam will continue to emerge, which is normal. Then let it sit for 10 minutes and rinse with water.

2. Lemon limescale.

Slice the lemon and put it in a kettle (the thinner the better, the purpose is to release the citric acid as much as possible) The water is boiled and boiled for about 5 minutes, after boiling, let the lemon soak in water for 2 minutes, and then rinse with water to remove the scale.

3. Starch descale.

Starch can be made with ingredients such as potatoes or yams. You can cut the skin of the potatoes and put them in a kettle with scale, add an appropriate amount of water to boil, and boil for about 10 minutes to remove the scale. In addition, the scale and stains on the surface of the stainless steel faucet can also be wiped with potato peels to remove them.

Method 1: Place the container with limescale. Pour in the vinegar, pick up the container and shake it, let the vinegar soak in the places with scale, shake it a few more times, and leave the container for about 20 minutes.

After 20 minutes, you can find that the scale has begun to fall off, in order to remove the scale more cleanly, you can pour warm water into the container and submerge the limescale area. Soak for about half an hour, the longer the time, the better the effect. After soaking, you can notice that the limescale at the bottom of the container is almost all off.

Wash the container.

The main ingredient of edible vinegar is acetic acid, and the main components of scale are calcium carbonate and magnesium carbonate. When edible vinegar and limescale meet, calcium acetate and carbonic acid are produced. Carbonic acid can be broken down into carbon dioxide and water, and the calcium acetate formed can also be soluble in water.

Therefore, it can remove limescale, and it is recommended to use strong vinegar for better results. The reason for soaking in warm water and vinegar is that the reaction is faster and the effect is better.

Method 2: Slice the lemon and put it in a container with limescale. If the container can be heated, you can heat it to boil the water, and then leave it for about 10 minutes without moving.

If the container cannot be heated, it can be poured in and start soaking for 20 minutes. The higher the temperature, the better the dissolution.

The main component of lemon is citric acid, which is a weak acid. After heating, the weak acid reacts with the scale, causing the scale to fall off. The more lemons, the higher the acidity.

The better. The citric acid detergent products sold in the market are extracted from lemons. Because of the high purity of the extraction, the effect is good.

Method 3: Remove limescale from the egg shell, and after eating the egg, the egg shell can be put away. Place egg shells in a container with limescale.

Add two-thirds of the water and shake for 10 minutes. The principle of this method is a physical principle, because the egg shell and water rub against the scale with the force of shaking in the container, and the scale can be effectively removed. This method requires the addition of egg shells depending on the size of the container.

Method 4: Starch descale. For potatoes, potatoes and other foods containing starch, put potato skins and sweet potato skins into a container with scale, pour the container clearly, and leave it for about half an hour.

Because starch has a sticking effect, this method is suitable for scale, and thinner scale containers cannot be effective against very hard scale.
