How much can the formaldehyde be reduced by opening the window for ventilation, and will the formald

How long does it take to remove aldehyde by ventilation depends on the materials used in decoration, the release life of formaldehyde is generally very long, can reach 3 to 15 years, there are many materials that can release formaldehyde, and it is easy to exceed the formaldehyde standard when the ventilation is not smooth, so how to control formaldehyde in a safe range for a long time, recommend several easy-to-use methods to everyone.

1. Wise Stone.

It can actively adsorb indoor free formaldehyde, the process will not be affected by any external factors such as temperature, humidity, light, etc., the adsorption rate of formaldehyde is also dozens of times that of ordinary adsorption materials, in addition to the unique decomposition function, the adsorbed formaldehyde can be decomposed into harmless carbon dioxide and water, and then discharged, so that its internal pores have been in an unsaturated state, and the aldehyde removal rate can reach more than 90%. When choosing, it is important to note that it is a gray ore with an irregular shape and is not a round particle

2. Wind fan.

We all know that the easiest way to remove formaldehyde is to ventilate, the room ventilation is not in a good state of the family, through the fan to accelerate the indoor and outdoor air flow, accelerate the discharge of formaldehyde-containing air, can effectively reduce the indoor pollutant concentration, but it can only treat the symptoms can not cure the root cause, and this method may not be very practical in the season when you need to keep warm.

3. Activated charcoal.

Activated carbon is a more effective way to purify the air, it has a strong adsorption effect on harmful substances such as formaldehyde, and the smaller the particles, the better the adsorption effect. It should be noted that most activated carbons have certain adsorption limits, and once saturated, they will no longer be absorbed, but will appear desorption, releasing absorbed harmful substances.

Fourth, photocatalysts.

Photocatalyst is an auxiliary method for the treatment of formaldehyde, mainly because it cannot decompose formaldehyde in the dark or under lightless conditions, cannot operate around the clock, and its range of action is small, and it cannot effectively remove formaldehyde in the room deeply. In addition, photocatalyst itself is a chemical and needs to be used with caution.

Fifth, the fresh air system.

The fresh air system can introduce fresh air outside and discharge harmful substances from the indoor space through the system's filtration device during the period when the windows cannot be opened, which will reduce the concentration of free organic pollutants in the indoor space to a certain extent and speed up the release of pollutants. Through continuous circulation, the indoor decoration pollution is controlled.

Summary: Formaldehyde is very harmful, and the selection of furniture and decoration materials should be strictly controlled when decorating new houses to reduce formaldehyde from the source.

There is no fixed value, because the release of formaldehyde is not fixed, it will change with time, temperature, humidity, ventilation conditions and its own conditions, forming a wavy curve. One of the most influential is the quality of the itself. For example, the pollution reduction of lacquer products will be larger, and the pollution of plates will be less, especially if it is well closed.

Look at the temperature difference and whether there is wind, the larger the temperature difference, the faster, and the faster the wind.

No, unless the formaldehyde value in the air is also exceeded. Ventilation will only speed up the volatilization of formaldehyde, the better the air fluidity, the faster the formaldehyde will dissipate, but the formaldehyde removal cycle will be longer.

Answer: If you keep ventilation all the time, the formaldehyde in the house should be within the safety range of the national standard, but it is not once and for all. Because in some conditions it is not suitable to open windows for ventilation. It is not suitable to open windows on hazy days, rainy days, and windy days.

Of course, the formaldehyde in the ventilation room will not exceed the standard under normal circumstances, unless there is a poorly ventilated place, such as the basement, cloakroom, etc.! This is not much different from the outdoors, this is the principle of ventilation and formaldehyde, fundamentally speaking, in fact, it is not to remove formaldehyde, but to replace the air with the outdoors, the indoor air and outdoor convection, ventilation, in fact, there is no effect on the release source, the amount of release, not to talk about this at all.

As we all know, the incubation period of formaldehyde can reach more than ten years, it is not easy to completely remove it, and the application of various materials and accessories for home decoration may release formaldehyde, all we can do is to control the formaldehyde content within the safe value range, and it takes a long time to remove formaldehyde.

In short, without being affected by the outside world, the house has been open windows for ventilation, which is the most ideal method to remove aldehyde, if the formaldehyde in the house still exceeds the standard, then the release of formaldehyde has reached a very serious point.

After the decoration of the new house, the floor, wallpaper, and wardrobe will release formaldehyde, especially the inferior decoration materials, the release of formaldehyde will last for more than ten years, so how should we deal with formaldehyde? Here are a few ways to do it.

1. The fresh air system can ensure that the home is in a ventilated state for 24 hours, which can greatly increase the exchange of indoor air and the outside world, although the effect is very good, but the first of this fresh air system is more expensive, and the installation before decoration is a better choice.

4. Plants can remove formaldehyde, although formaldehyde can be removed, but the amount of formaldehyde absorbed by it is very limited, and when the indoor concentration is high, if it simply relies on plants to adsorb formaldehyde, its dosage is very large.

5. We all know that formaldehyde is volatile at high temperature, and we can use some heating equipment to increase the temperature at home a lot, so that a large amount of formaldehyde gas can be volatilized, and then formaldehyde can be removed by opening windows for ventilation.

Repeated operation a few times, you can remove most of the formaldehyde in the home, but we must pay attention to safety when using heating equipment to avoid fire

The correct way to open windows for ventilation to remove formaldehyde, how to remove formaldehyde is the most effective and fastest way to remove formaldehyde.

If your home is north-south transparent, you can open the windows on both sides, which is more advantageous. Releases formaldehyde in the house. In fact, the release of formaldehyde through the window is only a part, and it is still necessary to start from the time you come to the house to start treating formaldehyde.

Dilute formaldehyde plants, so that formaldehyde can be diluted more effectively. Therefore, a good material at home can avoid formaldehyde from harming the human body. Happy New Year, I wish you good health, I wish you happiness, I wish you happiness!

Open the window to let the air circulate, several times a day, so that the formaldehyde smell can come out.

Just open the window to speed up the air circulation, and you can use an electric fan to blow it.

After the decoration of the home formaldehyde detection is not detected must be exceeded, and most of the formaldehyde is emitted in half a year, at this time in addition to formaldehyde, you have to insist on opening the door and windows for ventilation, and then to activated carbon, green plants as the auxiliary, after half a year, most of the formaldehyde emission standards at home (below) and then move back home, as for the other small amount of formaldehyde, although it takes more than ten years to emit, there is no harm to people, please adopt.

Measuring formaldehyde concentration requires sealing the room for 12 hours before testing, which is the most scientific and accurate. The most common way to remove formaldehyde indoors is to open windows for ventilation, which is the simplest and most convenient, and it is also a zero-cost method, but it is also related to the location of the house, the house type, and the weather, so if you want to only use the ventilation method to remove formaldehyde, it is not very stable, and it will be subject to many restrictions.

1. Wise Stone.

It is a purification product favored by decoration families in recent years, compared with other formaldehyde removal products, its own pores are more, with the dual function of absorption and decomposition, and the speed of formaldehyde removal is also fast. Its unique decomposition function can save the time of drying, and it is more convenient to use, which can effectively control the formaldehyde problem for a long time. When choosing, it is important to note that it is a gray ore with an irregular shape and is not a round particle

2. Plants.

Plants such as aloe vera, cactus, and pothos have a certain ability to absorb formaldehyde, and can slowly consume the surrounding formaldehyde through photosynthesis. Because it is a plant, it is very safe and does not produce other harmful effects. However, it should be noted that the absorption of formaldehyde by plants is limited and can only be used as one of the comprehensive treatment methods to remove formaldehyde

3. Activated charcoal.

Activated carbon is a traditional physical adsorption material, which has been well received in the treatment of indoor and outdoor pollution, its specific surface area is large, and it has a strong adsorption capacity, but its adsorption capacity is limited, and it does not have the function of decomposition.

Fourth, high temperature.

In the case of high temperature, it can promote the conversion of formaldehyde in the bound state into free formaldehyde and reduce the total content of formaldehyde, because formaldehyde penetrates deep into the board, although formaldehyde cannot be completely removed, but its effect is still very obvious.

5. Formaldehyde remover.

Formaldehyde scavenger actively adsorbs, captures and reacts to formaldehyde free molecules, once the reaction generates non-toxic polymer compounds, so as to achieve the purpose of quickly and effectively eliminating formaldehyde, but it itself is a high concentration of chemicals, although it is harmless to the human body, but it is also recommended that you pay attention to safety when using it, and use it as little as possible.

Formaldehyde is a high-ranking toxic substance, but also a potential carcinogen, before moving into a new house to remove formaldehyde is an urgent job, according to the above, you can choose a variety of methods at the same time.

Opening windows for ventilation can reduce formaldehyde. Therefore, ventilation should be carried out frequently in daily life, and it is the correct measurement method to use a special formaldehyde measuring instrument for measurement.

Open the window for ventilation in this case will definitely be able to reduce formaldehyde, often open the window you will find that the air in the house will become very good, and the air will become very smooth, you can also put some green plants in it, which is better.

Formaldehyde should be closed for 24 hours before being measured with a professional instrument. Opening windows for ventilation can reduce formaldehyde, and the most important way to remove formaldehyde is to open windows for ventilation.

It is unrealistic to completely remove formaldehyde through window ventilation, because the release life of formaldehyde is very long, it can reach 3 to 15 years, if you wait until then, the decoration may be outdated, and the current more reliable is to stabilize it within a safe range, and recommend several easy-to-use methods to everyone.

1. Green plants, aloe vera, cactus, pothos and other plants have a certain ability to absorb formaldehyde, and can slowly consume the surrounding formaldehyde through photosynthesis. Because it is a plant, it is very safe and does not produce other harmful effects. However, it should be noted that the absorption of formaldehyde by plants is limited and can only be used as one of the comprehensive treatment methods to remove formaldehyde

2. Activated carbon is a traditional physical adsorption material, which has been well received in the treatment of indoor and outdoor pollution, its specific surface area is large, and it has a strong adsorption capacity, but its adsorption capacity is limited, and it does not have the function of decomposition.

5. Photocatalyst, as the name suggests, is a catalyst mentioned in our junior high school chemistry, which decomposes formaldehyde into carbon dioxide and water through light, reduces the formaldehyde content in the room, and achieves the purpose of removing formaldehyde

Hello, after inquiry, in addition to formaldehyde, close the window for a week and then open the window, only fully let it play a role in removing formaldehyde, but this also depends on the specific situation, some time or even longer. As long as the temperature of the indoor space is not lower than minus 19 degrees, the general formaldehyde will slowly volatilize, the higher the temperature, the faster its release, especially the temperature exceeds 25 degrees Celsius. Therefore, when the temperature is high, be sure to open the window for ventilation.

Generally speaking, the frequency of opening windows for ventilation in winter is higher, and the windows are opened for ventilation once every three to five days. In summer, the frequency of opening windows for ventilation is lower, and the windows are opened for ventilation once every five to seven days.

Under normal circumstances, formaldehyde can be released after three to fifteen years of ventilation by opening windows. However, the specific time is not fixed, many materials in modern decoration contain a certain amount of formaldehyde, when reaching a certain concentration, it will cause serious harm to the body, and the speed of formaldehyde release has a certain relationship with temperature, indoor wind speed and the sealing of decoration materials. In the case of higher temperature and better ventilation, the release of formaldehyde is relatively fast, if the formaldehyde in the air exceeds the standard after decoration, formaldehyde can be removed with the help of other auxiliary measures, such as photocatalyst decomposition and chemical gas purification method, etc., to quickly remove formaldehyde, reduce indoor formaldehyde concentration to meet the occupancy standard.
