Ventilation skills for new houses in winter, how to open windows to ventilate and remove formaldehyd

1. After the decoration of the new house, the doors and windows are opened for ventilation, which can discharge the toxic substances indoors to the outdoors, and at the same time can speed up the drying speed of the paint, but the outdoor temperature is very low in winter, and the latex paint will reduce its own adhesion in a low temperature environment, and even the situation of chalking, so the warm afternoon should be selected for ventilation in winter, and the ventilation time should not be too long each time.

2. If the indoor space is relatively small, when the outdoor temperature is low and windy, the ventilation time should be shortened, on the contrary, if the outdoor temperature is relatively warm and windless, the ventilation time can be extended. Under normal circumstances, a 60-square-meter house with no wind or breeze can reduce the number of pathogenic microorganisms by 60% if the windows are open for 20 minutes.

3. Because of the cold weather in winter, it is recommended that you open the doors and windows for ventilation in the morning, noon and evening every day, and the ventilation time should be controlled within 20 minutes each time. Many people think that the longer the window is opened, the better, but this is not the case, and the frequent opening of the window after winter decoration will affect the effect of the wall paint.

4. If the outdoor traffic flow is relatively large, the window opening time should be adjusted when opening the window in winter, the window opening time can be earlier in the morning, and the window opening time can be delayed at night, try to choose the window for ventilation when the traffic flow is small, if the wind and sand weather is encountered, the screen window should be closed, the window should not be opened too large, and the humidifier should be used to increase the humidity of the indoor air.

Summary: The relevant content of how to ventilate the newly renovated house in winter is introduced to you here, I hope to help friends in need. After the renovation of a new house, you should use the correct method to remove indoor pollution, and pay attention to indoor ventilation, so as to create a comfortable and healthy home environment for yourself and your family.

When you are not at home, open the windows as much as possible to ventilate (pay attention to anti-theft and water pipes to prevent freezing).

After returning home, you can leave a small gap for ventilation according to the actual situation.

The general principle is to ensure both ventilation and prevent freezing of people or objects.

In winter, the temperature difference between indoor and outdoor is large, in this environment, if you blindly open the windows of the newly renovated new house for ventilation, the newly installed wallpaper, furniture, etc. may have different degrees of blistering, cracking and even falling off. Moreover, if you only rely on opening the window for ventilation to remove formaldehyde, you need to keep the window open 24 hours a day, and the aldehyde removal effect cannot meet expectations for the situation that it is inconvenient to open the window in winter. Here are a few recommended aldehyde removal methods suitable for winter, I hope to help you.

1. Under certain conditions, the formaldehyde scavenger reacts with formaldehyde to generate other substances that are not harmful to health, so as to reduce the concentration of formaldehyde in the room. But it's also a chemical in its own right, and if used incorrectly, it can be another source of pollution indoors.

2. 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 the plant simply relies on the adsorption of formaldehyde, its dosage is very large.

3. There are a large number of irregular pores inside the activated carbon, among which the pores similar to the formaldehyde molecule will adsorb formaldehyde, which can achieve the purpose of purifying the air, but the number of internal pores is limited, and it may cause secondary pollution when the adsorption is saturated.

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.

6. There are many formaldehyde removal companies on the market today, and it is difficult for us to distinguish whether the formaldehyde removal company is regular, and there is no absolute formaldehyde removal in the market

For the removal of formaldehyde in winter, we can open the window to remove formaldehyde, but the removal of formaldehyde by opening the window is to pay attention to skills, let's learn some methods to remove formaldehyde in winter.

1. Open windows for ventilation.

Our most commonly used method of removing formaldehyde is to open the window for ventilation in the new house, but many people think that opening the window for ventilation can remove formaldehyde, in fact, before we open the window for ventilation in winter, it is best to close the indoor room, and then turn on the air conditioner, and adjust the temperature to the highest, so as to keep it for a day. Wait until the next day, and then open the windows of the new house for ventilation, which is the most effective way to remove formaldehyde. We close the room and increase the temperature in order to release more formaldehyde, and when the formaldehyde is released enough, we are ventilating, so the effect is the best.

2. Place some green plants indoors.

We know that some common pothos, saxifera and other plants can adsorb formaldehyde very well, if the formaldehyde concentration in our home is not particularly high, we can put some green plants indoors, and accompany the opening of windows for ventilation, so that formaldehyde can be well removed. However, if the concentration of indoor formaldehyde is too high, green plants may face the danger of death, at this time we need to consult professional understanding and use some professional formaldehyde removal products.

Opening windows for ventilation is the simplest, but also a zero-cost method of removing aldehyde, but the windows are easily affected by the weather and season, and are also easily affected by the house type.

1. The blades of the fan can cut the air to promote the airflow in the process of rotating, so as to realize the replacement of indoor and outdoor air, accelerate the discharge of formaldehyde-containing air, and effectively reduce the concentration of indoor pollutants, but it can only treat the symptoms but not the root cause, and this method may not be practical in the warm season.

2. Green plants, aloe vera, cactus, pothos and other plants have a certain absorption capacity for 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. There are a large number of irregular pores inside the activated carbon, among which the pores similar to the formaldehyde molecule will adsorb formaldehyde, which can achieve the purpose of purifying the air, but the number of internal pores is limited, and it may cause secondary pollution when the adsorption is saturated.

4. The fresh air system is to purify the outdoor air through the fresh air fan, and then pour the fresh air into the room, but because of its cumbersome installation, it must be completed before the decoration, and it is high, so in general, the fresh air system is only suitable for large industrial enterprises or large office areas, as well as families with high budgets.

5. Formaldehyde will produce faster thermal movement under the action of high temperature, so that formaldehyde is released from the substrate, but it is difficult to completely remove indoor formaldehyde through high temperature, because the release life of formaldehyde is very long, continuous heating is not realistic, and in the process of using heating equipment, we should also pay attention to electricity safety.

Formaldehyde is very harmful to the human body, and it is recommended to use a combination of methods when dealing with it, so as to stabilize the formaldehyde concentration in a safe range faster!

After ventilating the new house for half a year, Mr. Ma moved in directly with peace of mind. But what he and his family didn't expect was that after living in it for less than two weeks, the family had symptoms of physical discomfort one after another. Especially the youngest son, not only always coughing, but also had an allergic reaction on his body.

Later, I took the child to check it and learned that it was formaldehyde poisoning.

Mr. Ma's family was stunned, they didn't expect that the formaldehyde was still in the room after such a long time of ventilation!In order to solve this problem as soon as possible, Mr. Ma found an expert in this area. Experts told him that relying solely on ventilation could not completely remove formaldehyde.

Because ventilation also needs to meet certain conditions, it is not as simple as opening the window. First of all, the weather conditions outside are required to be good, otherwise in case of rain, haze and other weather, the window will not be opened at all; Secondly, on the basis of ensuring that the windows can be opened, there must be sufficient natural wind. If there is no wind outside, then the formaldehyde cannot be sent out with the windows open.

It can be seen that the effect of ventilation to remove formaldehyde is very unstable, so experts tell people that multiple methods should be used together when removing formaldehyde.

Good method 1: This is a very accurate formaldehyde treatment material, put it in the room with excessive formaldehyde, and people don't need to do too much. It can adsorb formaldehyde into its own micropores in a targeted manner, and then decompose it to completely convert formaldehyde into substances that are not harmful to people and release it. In this way, it can continue to be used for more than five years, during which there is no need to worry about failure, and it is very worry-free to use.

Good method 2: bamboo charcoal.

The use rate of bamboo charcoal in life is not low, and its adsorption capacity is recognized by many families. However, this material only has adsorption, and it cannot continue to function when it is adsorbed to the limit. Therefore, it has a short expiration date, and a new batch has to be replaced every half month.

Good method three: high temperature.

When the temperature rises, the volatilization rate of formaldehyde will also accelerate, which also shortens the release cycle of formaldehyde to a certain extent. Then we open the windows and use the natural wind outside to bring formaldehyde out, which is much more efficient than simple ventilation. It's a pity that the indoor can't be in a high temperature state all the time, and it is easy to burn the furniture and even cause disasters!

How to open the windows to ventilate and remove formaldehyde in a new house in winter? Because formaldehyde has a great impact on human health, for this reason, indoor ventilation needs to be paid attention to. What are the ventilation skills of formaldehyde window opening in winter? PChouse will take you to find out.

First of all, the most important thing for ventilation is to open the windows, and there must be wind passing through. In this way, the air can form a convection, which promotes the displacement of indoor and outdoor air and takes away the formaldehyde in the room. If there is no wind, we can also turn on the electric fan and use the wind of the electric fan to drive the air flow and enhance the ventilation effect.

Secondly, it is better to stuff the house for a few days before ventilating it. If conditions permit, you can also put some heating equipment indoors to increase the temperature in the room and speed up the release of formaldehyde. This shortens the ventilation time and makes the effect even more significant.

Finally, due to the relatively large mass of formaldehyde, it is easy to accumulate in the corners of the room. Therefore, when ventilating, it is best to open the cabinets in the room, which is conducive to the flow of air and avoids the accumulation of formaldehyde in the corners and exceeds the standard.

However, the release period of formaldehyde is as long as 15 years, and we will not open the windows when the weather is cold like winter, which will greatly reduce the actual effect of ventilation. Therefore, it is recommended that when ventilating, it is best to use some other methods.

Open the windows for ventilation when the weather is good, such as sunny and windy weather, and don't open it in rainy and snowy weather to avoid moisture.

Principle: Through the circulation of indoor air, the content of harmful substances in indoor air can be reduced. Advantages: easy to operate and low cost.

Disadvantages: It is easy to be limited by weather, time and other factors, such as (rainy days, nights) is not suitable for opening windows; The speed of formaldehyde removal is relatively slow and takes a long time, generally about half a year.

**: 02, green plants, tea, etc. The role of green plants and tea is relatively small, and the role of green plants is mainly to regulate indoor air humidity, not to remove formaldehyde, and tea is basically to cover up the smell.

3. Photocatalyst. Some people say that photocatalyst is useful, but I don't recommend it personally, so you can check what Akira Fujishima, the father of photocatalyst, said! He is a specially invited foreign academician of the Chinese Academy of Engineering, a foreign expert of Peking University, and a famous Japanese photochemical scientist, Professor Fujishima Akira, who clearly explained that photocatalysts need ultraviolet light products, and the effect of products without ultraviolet light is very bad and almost useless.

1. Open windows for ventilation.

2. Place some green plants indoors.

In winter, formaldehyde can be removed by putting salt water in the new house, indoor ventilation, increasing the indoor temperature, using green plants to adsorb round resistance, and using activated carbon adsorption.

1. Put salt water in the new house.

Using the water-soluble property of formaldehyde, you can put a few basins of salt water in each room, so that you can initially absorb a large number of pungent odors in the room.

2. Indoor ventilation.

Formaldehyde is a volatile substance, which can be used to open all doors and windows in the room to maintain air convection inside and outside the house, so that it can be maintained for about 2 months.

3. The temperature in front of the indoor belt is increased.

The volatilization rate of formaldehyde is generally very slow, if you want it to volatilize as soon as possible, you must try to increase the indoor temperature, and you can turn on the air conditioner at an appropriate amount of time to increase the indoor temperature to speed up the volatilization rate of formaldehyde.

4. Green plants.

The plant adsorption method is also a good spring selection of oranges. After a large number of investigations and studies by scientists, many green plants such as spider plant, cactus, tiger tail orchid, iron tree, chrysanthemum, etc. have a strong ability to absorb formaldehyde. These plants can effectively absorb formaldehyde while decorating the room, which is one of the common methods to remove formaldehyde in new houses.

5. Use the adsorption effect of activated carbon.

Use some substances with strong odor adsorption to improve indoor air quality. At present, the more popular and most used on the market is activated carbon, which can play a good role in the adsorption of formaldehyde by placing about 50g per square meter, but at the same time, attention should be paid to the replacement of activated carbon, which is generally appropriate once every 7-8 months.
