The scale in the kettle is very thick, add some soaking to it, and it will become clean in a few minutes
When it comes to electric kettles that contain limescale at home, I'm sure many people have encountered such problems. When heated, the residue in the water will form limescale and adhere to the electric kettle. After a long time, it was a thick layer that was so hard that it could not be cleaned at all.
What exactly is limescale?
Limescale is usually a precipitation of calcium and magnesium in water.
He is often referred to as total hardness.
Due to the difference in cations in water, it is divided into carbonate strength and non-carbonate hardness.
When not boiled, the vast majority of calcium and magnesium in water are in the form of bicarbonate, and calcium and magnesium do not precipitate.
After boiling, a part of the bicarbonate is converted to carbonate and sediments appear. This sediment can be removed, and the salts formed by this salts are generally referred to as temporary strength.
It is more convenient to express the intensity in the unit with the same concentration.
Boiler fouling can cause the following injuries:
1) Waste of fuel.
After the boiler fouling, the heat transfer of the boiler will be reduced, and the heat caused by fuel combustion cannot be transferred to the boiler water quickly. A large amount of heat is fixed by the exhaust gas, resulting in an increase in the exhaust gas temperature, an increase in the exhaust gas heat loss, and a decrease in the calorific value of the boiler. Depending on the type of scale, the total amount of material wasted will vary.
The property damage caused by boiler fouling is staggering. According to related reports: for thermal equipment, 1mm needs to consume 7%-9% more scale and reduce thermal efficiency by 10%-20%. In China, 17% of refined coal is consumed annually due to scaling of boilers and other equipment. 5mt。
2) Damage to the heating surface.
When the boiler is in normal operation, the metal material barrel will quickly transfer heat to the pot water after being heated, and the temperature difference between the two is about 30-100; Due to the reduction of heat transfer performance, the heat of the scaling boiler cannot be quickly transferred to the water of the boiler, so the temperature of the metal wall thickness of the scaling part will increase. This results in a decrease in the strength of the metal. Depending on the type of scale, the thickness is different, and the temperature of the pot is also different.
Calculation: When the boiler has 3 mm coarse scale, the ambient temperature of the construction steel rises from 280 to 580, and the compressive strength is usually 396*106N m2 drops to 0984*106n m2, in this way, under the action of pipeline pressure, the internal structure of the pipeline will be deformed, resulting in major accidents such as bagging and even bursting.
3) Disrupt the water cycle.
When the boiler scales, because the heat conduction is not very good, it will reduce the evaporation of water and reduce the boiler load rate. Therefore, in order to achieve the rated load rate of the boiler, it needs to consume more material. However, with the increase of scale thickness, the boiler efficiency will be further reduced due to the fixed total heat conduction area of the boiler and the limited fuel consumption.
Therefore, it is necessary to invest in a new boiler, it is necessary to carry out a boil in a new boiler. Since its establishment in 2009, Foshan Geyuan Environmental Protection has many years of experience in boiler cleaning. Of course, for the boiler before the new furnace is put into service, the pre-film of the newly installed steam boiler boiler can be used to remove grease and rust, creating a protective film against scaling and corrosion.
Especially in the electric kettle, if there is a lot of limescale in it, it is easy to slow down the boiling water, and the sound of boiling water becomes loud. Therefore, it is very important to remove limescale and clean it with a regular wire brush. Now I will teach you some small methods that are very effective.
First, prepare a damp cotton cloth in advance, which can be a wet paper towel, and pour in some edible vinegar, white rice vinegar, black vinegar or even vinegar essence. Then scrub evenly in the kettle with a towel several times to allow the edible vinegar to stick to the inner wall of the kettle. This applies to teapots with less limescale in the teapot. You can wipe it off with a damp paper towel. If the limescale is thick, it is recommended to add two-thirds of cold water to the pot, then pour one-third of the cold water, soak for half an hour, insert and boil the water. At this point, even if the scale is thick, it can basically be melted by glacial acetic acid. When boiled, the water becomes cloudy because the limescale breaks down. Throw it away immediately.
Cut half a lemon, squeeze the lemonade into an electric kettle, soak in water for half an hour, and bring to a boil. This is similar to the method of using cooking vinegar, but it is important to note that only press the lemonade into the pot and do not put all the green lemons in the pot to boil. Because the electric kettle can only be a boiling liquid, naturally, if soaked in an electric bubble, you can cut the lemon slices into shreds.
The above two methods are to use some ingredients at home to divide scale, and the basic principle is similar, that is, to use their acid and alkali to react with the important chemicals of scale, and then remove, the method is relatively simple and convenient. It's worth a try for everyone, don't worry about residues, physical and mental health.
But instead of removing limescale frequently, it is better to find a way to make the water in your home cleaner, because the residue is reduced, of course, there is less limescale, and it is safer and more secure to drink.
I believe that everyone will encounter a problem when cleaning the bathroom, that is, there are many water stains on the glass partition wall of the bathroom, and these water stains are difficult to remove.
In particular, bathroom mirrors and appliances such as faucets are prone to water stains and limescale. It's uncomfortable to see him every time, and it's time-consuming every time.
I like to clean him with a glass cleaner before I clean him, but the total area of the glass partition wall in the bathroom is too large. Every time I clean, I have to clean with a bottle or two of glass cleaner, which is a waste of money.
After that, I saw a lot of internet celebrity bloggers pushing citric acid limescale cleaners, which are not only easy to use, but also cost-effective. One large bottle is food grade citric acid. Compared to other organic chemical detergents, its safety factor is more satisfactory!
It can be used as its own glass cleaner, and then bitter-washed laminated glass can be cleaned with it. The way to do it yourself is simple, add 500ml of hot water to the kettle, dig two spoonfuls of citric acid until it cools, and you also have a bottle of glass cleaner.
Because dust, limescale and water stains are all alkaline, plus acid-alkali citric acid, it can exert a chemical change of strong acid and strong alkali to dissolve water stains and scale. So, spray some on the glass and wipe it with a rag, and you can wipe the glass like new.
Its biggest advantage is that it is safe, citric acid is a green plant, fresh fruit itself, citric acid is also commonly used in some edible additives. The initial use may not feel very good, as it is softer than some strong scale removers, so the experience of use does not work immediately.
But it is also soft, so it is not easy to evaporate harmful substances in use. Although descaling is slower, it is not too slow. Spray paint on limescale areas such as laminated glass, showers, tap taps, and the foot of the shower room, let it sit for 10 minutes, and then gently wipe it with a fish scale cloth to easily remove scale.
In fact, many limescale cleaners react quickly and are highly efficient, but evaporate pungent vapors when used.
Due to the safety of citric acid, it can also be used to remove limescale from the bottom of an electric kettle. Add citric acid powder to the water and bring to a boil. After throwing away the boiling water, you can see that the scale in the pot is automatically removed, mainly because the scale is alkaline and the acid-base reaction melts.
As you can see, the actual effect of citric acid scale cleaner after application is really amazing, no matter how bad the scale is, it can be removed!
With it, all kinds of laminated glass and bathroom mirrors in the home are free of water stains and limescale, and life becomes more and more comfortable. For busy housewives, the citric acid limescale cleaner is really effective!
For household citric acid scale cleaner, be sure to choose food-grade plastic!
Only this citric acid is very safe. It is used to clean and kitchen supplies, so that it is more assured.
