How to prevent the formation of limescale in radiators?

The use of antiscalants, as the name suggests, is to add some antiscaling antiscalants to the water quality to avoid scaling. Antiscalants are made up of alkaline substances and organic and inorganic substances. The alkaline substance in the antiscalant causes the calcium and magnesium salts in the boiler water to form water slag, which is removed by draining.

In this way, calcium and magnesium ions are removed, making it not form a hard scale. The organic matter in the antiscalant will increase the fluidity of the slag and make it easy to discharge, and at the same time, the organic matter will also form a barrier layer on the metal surface, preventing the formation of scale on the metal surface. This series of chemical and physical actions prevents the formation of scale.

The top ten brands of radiators will add the antiscalant to the boiler water in operation, it will protect the entire system, including the radiator, the biggest advantage of this method is that the customer does not have to do it himself, by the community or heating company, at present, many heating systems have adopted this way, the effect is still good.

There are many cases where the radiator is not hot and the hot water is not running smoothly due to the blockage of the heating pipe, and the scaling of the heating is one of the main reasons for this state. For the independent heating method of the family, how to effectively prevent the heating chip scale and avoid the phenomenon that the radiator is not hot? Radiator companies say that heating users can easily learn two ways to quickly solve the problem of radiator fouling.

In daily life, we often find that after the radiator is used for a long time, there will be limescale on the inner wall that is difficult to remove. So, how does limescale form? As a terminal device for heat dissipation, the radiator pipe flows with 60-70 hot water, and sometimes the water temperature is even as high as 90 or more.

Water contains minerals such as calcium and magnesium, and during the thermal reaction, calcium carbonate, magnesium hydroxide and other substances precipitate and attach to the inner wall of the radiator, which is what we commonly call scale. Therefore, after many radiators are used for a period of time, there will be scaling on the pipes.

1.Use radiator antiscalants, which are a mixture of alkaline and organic substances. The alkaline substance in the antiscalant makes the calcium and magnesium salts in the water of the radiator pipeline form water slag, and the water slag is removed through the sewage discharge, so as to remove the calcium and magnesium ions in the water, so that it cannot form scale.

At the same time, the organic matter in the radiator antiscalant will also increase the fluidity of the water residue, making it easy to discharge, and form a barrier layer on the metal surface to prevent the formation of scale on the inner wall of the radiator.

2.Increase the number of radiator pieces or groups, and achieve low-temperature heating through this method, so that the temperature of hot water in the radiator pipe is reduced, which is not conducive to the precipitation and precipitation of calcium carbonate, magnesium hydroxide and other substances, and will not form scale on the radiator pipe. If you choose a radiator with better internal anti-corrosion treatment, the effect of preventing scaling of the radiator will be better, because the anti-corrosion coating of the radiator reduces the adhesion of the inner wall, and there is no place where minerals such as calcium and magnesium are attached, and the radiator is not easy to scale.

Of course, if there is scaling in the radiators, boilers and pipes at home, users can find a professional descaling company to remove the scale, and they can easily remove the scale in the heating without doing it themselves, so that the heating system can run smoothly and the radiators heat up. If you have the knowledge you want to know about HVAC, you can also send a private message to Fengdu, and Fengdu will continue to provide you with more radiator knowledge.

The presence of scale and corrosive substances will have a certain resistance to the flow of hot water, which in turn will affect the heating effect.

If the scale of the radiator at home is serious, you can contact a professional descaling company to clean it, whether it is a pipe or a radiator, you need a clean environment, and the radiator should be deeply cleaned in time. At the same time, you can choose to replace some radiators with good anti-scale performance, and the radiators of regular manufacturers use nano anti-corrosion technology, which not only ensures that the radiators will not be corroded, prolongs the service life, but also can better prevent scaling and facilitate the use of users.

You can also clean it yourself. First close the radiator inlet valve and return valve, and then use a wrench to open the plug of the radiator to drain the water, there will be water outflow when it is just opened, so it is best to catch it with a basin. Open the inlet valve of the radiator to let the water flow into the radiator and let the water flow out of the plug.

Until the water that flows out becomes clear. After cleaning, close the plug, then open the exhaust valve, and then open the inlet valve of the radiator, so that the hot water in the heating system will go in, until the hot water flows out of the exhaust port, indicating that it is full. At this time, open the outlet valve, and the whole cleaning process is completed.

Radiator scale cleaner is mainly used to remove carbonate-based scale; The main ingredients of radiator scale cleaning agent: organic acid, corrosion inhibitor, penetrant. Key features:

The radiator scale cleaner is fully organically formulated, and the solid packaging is easy to transport and use; Radiator scale remover cleaning agent is non-toxic, odorless, non-flammable and non-explosive; The radiator scale cleaner has good water solubility, high corrosion inhibition rate, and minimal damage to the equipment; Radiator scale cleaner is suitable for copper, stainless steel, carbon steel and galvanized and other metal materials, with high scale removal efficiency, low corrosion rate, safe and convenient use.

Radiator scale remover cleaning agent is suitable for cleaning scale in heating circulating water system, scale removal in heating circulating water system, scale removal in heat exchanger radiator and scale removal in tea stove, water tank, electric water boiler, etc.

We are happy to answer for you: How to remove the scale inside the radiator? A:

1. If there is scale in the radiator, we can pour an appropriate amount of antiscalant into the water of the radiator, and the antiscalant can prevent water from being generated in the water. Dirty. However, this method is generally carried out by the community or the heating company, and many heating companies have added antiscaling agents to the heating system before the formal heating, so the owners do not need to operate it themselves.

2. The water in the radiator contains a large amount of carbonate and other substances, at this time, we can connect the water pump externally, and then add some dilute hydrochloric acid to the radiator, and then add a little hot water, so that the dilute hydrochloric acid in the radiator is continuously circulated, so as to dissolve the scale in the radiator, and finally put the sewage in the radiator away, and then put in clean water to clean it up.

1.Prepare to clean props. Prepare the cleaning tools in advance, we need a wrench, a basin.

2.Close the inlet and return valves. Close the inlet and return valves first, and then use a wrench to open the plug of the radiator to drain the water, there will be a lot of water when it is first opened, so it is best to use a basin to catch it below.

3.Clean the radiators. To conserve water, you can use water from the radiator for the first flushes and tap water for the next flushes.

Turn on the inlet switch of the radiator to let the water flow into the radiator and let the water flow out of the plug. Until the water coming out of the radiator is clear.

4.Install a reheating system. After cleaning, close the plug, then open the exhaust valve, and open the water inlet of the radiator so that the hot water in the heating system goes in until the hot water flows out of the exhaust vent indicating that it is full.

At this time, open the water valve at the shouting place, and the whole cleaning process is completed.

How to maintain radiators:

Exhaust work. When there is air inside the radiator, the exhaust valve on the radiator should be used to remove the air in the system in time to prevent the chemical reaction between oxygen and the inner wall of the radiator from causing oxidation and corrosion of the radiator. Generally, the heating system needs to be debugged for the first time, and the user needs to open the exhaust valve of each radiator to discharge the air accumulated in the radiator, or open the exhaust valve installed in the gas collection tank installed on the top of the system to exhaust the air.

After the exhaust is completed, the valve should not be opened and closed casually to avoid the valve being screwed.

Full water maintenance. After the heating period, the user does not discharge the water in the heating system, but exhausts the radiator once, exhausts the air inside, and carries out "full water maintenance" on the radiator and pipes. "Full water maintenance" is mainly to prevent oxidation from occurring in contact with the air in the pipes.

Reducing the risk of corroded radiators and heating pipes can extend the life of your heating system.

Pay attention to the heat dissipation of the heater. It is best not to pile up debris or heavy objects at the upper end or in front of the radiator, the pressure bearing capacity of the radiator is not good, if the things placed are too heavy, there may be safety accidents, and placing too many items will affect the heat dissipation of the radiator.

Prevent the radiator from bumping. When using, you should also pay attention not to bump or scratch the radiator to prevent the surface spraying from falling off, and if you do not deal with it in time, it will cause the radiator to corrode. Therefore, we often have to clean the radiators to avoid stains.

How to deal with scale outside the radiator: descaler formula: 1 part of salt, 3 parts of white vinegar, salt and vinegar with 1:

After mixing and stirring evenly in the ratio of 3, it is used to wipe the sail and wash the scale, and the cleaning effect is relatively good, and the scale can be cleaned off quickly. Moreover, the substances formed after removing the scale are not toxic to the human body, but they are also inedible, so it can be rinsed with water again. There are several main ways to remove it:

1.Baking soda removes limescale. When boiling water in an aluminum kettle with limescale, boil for a few minutes and the limescale will be removed.

2.Lemon limescale removal. Put the lemon slices in a kettle and boil for about 5 minutes, then let the lemon soak in water for 2 minutes to remove.

3.Vinegar to remove limescale. A few spoonfuls of vinegar can be boiled in water to remove limescale.

If the main ingredient in the scale is calcium sulfate, the soda ash solution can be poured into the kettle and boiled to remove the scale. 4.Ion exchange scale removal method.

By using a specific cation exchange resin to replace calcium and magnesium ions in the water with sodium ions, the solubility of sodium salts is high, so the formation of limescale due to the increase in temperature is avoided. 5.Membrane separation removes scale.

Both nanofiltration membranes and reverse osmosis membranes can intercept calcium and magnesium ions in water, thereby fundamentally reducing the hardness of water. The characteristics of the membrane separation and scale removal method are that the effect is obvious and stable, and the treated water has a wide range of applications; However, there are high requirements for inlet pressure, equipment investment, and operating costs.

After the radiator is used for a long time, scale will be generated inside, so it is necessary to clean the inside of the radiator to remove the scale. There are many ways to clean scale, so how to clean the scale on the radiator? Let's take a look at the relevant content introduction.

1. If there is scale in the radiator, we can pour an appropriate amount of antiscaling agent into the water of the radiator, which can prevent the scale from being generated in the water. However, this method is generally carried out by the community or the heating company, and many heating companies have added antiscaling agents to the heating system before the official heating, so the owners do not need to operate it themselves.

2. The water in the radiator contains a large amount of carbonate and other substances, at this time, we can connect the water pump externally, and then add some dilute hydrochloric acid to the radiator, and then add a little hot water, so that the dilute hydrochloric acid in the radiator is continuously circulated, so as to dissolve the scale in the radiator, and finally put the sewage in the radiator away, and then put in clean water to clean it up.

3. If the radiator in the owner's own home has scale, it is best to find a professional to help clean the scale, so as to avoid problems such as water leakage of the radiator due to the owner's own wrong operation. The specific cleanup method is as follows:

1) Prepare to clean the props.

Before cleaning the scale of the radiator, we need to prepare the wrench, basin and other cleaning tools.

2) Close the inlet and return valves.

The next step is to close the inlet valve of the radiator, close the return valve, and then use a wrench to open the plug of the radiator to allow the water to flow out of the heating pipe. When it is first opened, a lot of water will flow out of the pipe, so you should use a basin to catch the water at this time to avoid causing the indoor floor to be damp.

3) Clean the radiators.

Next, we should turn on the water inlet switch of the radiator, so that the water can flow smoothly into the radiator, and then release it from the outlet of the radiator, at this time, we can use the water flowing out of the previous radiator, so as to save water resources. When the water coming out of the radiator becomes clear, the limescale in the radiator has been cleaned up.

4) Install a reheating system.

After the scale is cleaned, we need to close the outlet of the radiator, open the exhaust valve, and turn on the water inlet switch of the radiator, so that the new heating water can flow smoothly into the radiator. When you find that there is water flowing out of the exhaust port, it means that the radiator is full, and then you can open the water outlet valve.

The above is a detailed introduction to how to clean the scale of the radiator, I hope it can help friends in need. The scale in the radiator will not only affect the flow of hot water, but also affect the heating effect of the radiator, so it must be cleaned up in time.
