After the new house is renovated, you must not move in immediately, how long should you open the win

The new house can not be moved in immediately after decoration because there are harmful substances such as formaldehyde, and it can be moved in after two or three days of opening the window for ventilation.

Ventilation is in the house for a year, because ventilation for such a long time can volatilize some harmful substances inside.

The new house is well decorated, it is recommended to ventilate for more than half a year before considering moving in, and it is best to conduct a methanol test before moving in to ensure that it is not too late to move in safely, after all, safety is the most important.

First of all, if the newly renovated house is the reason for the unqualified quality and environmental protection of the decoration board, you will have formaldehyde continuously released in 10 years and 8 years; If it is a material that meets the requirements of environmental protection quality, then basically the formaldehyde content of formaldehyde release time up to 3-15 years, therefore, it is impossible to completely remove formaldehyde in a few days or even just a few months, open windows and ventilation should become a daily essential work, especially in summer when the temperature is high and the time of winter heating, when the amount of formaldehyde is released, it is necessary to keep the window open every day to ventilate and control within the national standard There is no problem.

Open in the morning or noon, close it at night, there is no need to open the window 24 hours a day, 24 hours open the window one is particularly dusty, the other is the humidity at night in summer, especially like the southern or coastal cities at night humidity is particularly heavy, wooden furniture is easy to deform in the humid space for a long time, just decorated house, many decoration materials may not be fully bonded, long-term feng shui may cause the wall to crack and the like, so the ventilation windows of the newly completed house can not be opened too much, It should be ajar for ventilation, and the windows can only be opened after a period of ventilation.

Specific analysis of specific problems, just renovated house, I am afraid that the construction materials inside are not completely bonded, and complete ventilation will produce cracking, and the gains outweigh the losses! What's more, if it is not convection ventilation, if it is only for the purpose of removing formaldehyde, it is not necessary! There is no need, I personally recommend that you just come to the wind every few days in winter, and you can do it once a day in summer, if you are lazy, I recommend opening a five-centimeter gap in each house, once a week, ventilating it, and watering the green plants.

Formaldehyde and other gases produced after decoration are gradually accumulated, not completely released at one time, so ventilation should be maintained as much as possible, and ventilation should be at least once in the morning and evening, so as to avoid indoor formaldehyde and other gases that exceed the standard after accumulation, resulting in unnecessary damage.

My home has just been repaired, I open the window during the day, turn on the air conditioner in each room at night, turn on the high temperature, seal the doors and windows, so that I live in it after a month, of course, all my furniture is solid wood, no industrial board, formaldehyde is more volatile on the surface of the formaldehyde content infinitely small amount of paint, and less use of composite wood furniture, from the source to reduce the formaldehyde content. It may be that every formaldehyde-containing product we buy can meet the national standard, but whether it can be put together without exceeding the standard is only known after testing.

A relative of mine moved in not long after the renovation was completed and passed away a month later! Formaldehyde poisoning! Life is more important!

If conditions permit, the paint is odorless, the wall is white, there is no ceiling, it is installed in two months, the furniture is all sample furniture, and the store has been placed for a long time, and it is determined that there is no smell. At that time, some children were particularly worried, but after a week of ventilation, they moved in, and now it has been 8 years.

Buy an electric fan in the room, blow on the wardrobe, blow it for 2 months in the summer vacation, blow day and night, but it is a little expensive and expensive to fan, so that it is much better after 2 months, it is best to use environmentally friendly paint and environmentally friendly materials, so that the effect is better, but after the ventilation is still indispensable as long as the wall is painted to buy furniture. Played panel furniture. It is recommended that it is best to ventilate for half a year.

If possible, it is best to ventilate for a year. Formaldehyde can only be fully volatilized for more than ten years. The evaporation period is 6 months.

That is, no matter how fast it is, you will have to wait for half a year to move in! There is only one human life.

It depends on the amount of board used in your house, how much doors and windows are replaced, how much floor is used, how much glue is used in the kitchen, how much is the amount of beauty sewing agent, how much glue is used for wallpaper, what material is used for curtains, what materials are used for sofas, and what materials are used for bed boards... Formaldehyde is used everywhere, and the volatilization time is 10-15 years. Therefore, it is recommended to pass through 1-3 months for three months.

Cabinet products, please remember to open all the doors, and there is little point in plants absorbing formaldehyde online. It's true, but you should also pay attention to protect your new home and don't let it rain, rain will get into the window, it will cause damage.

It is necessary to open the window for ventilation for a long time, so as to achieve a very good effect, because there are a lot of formaldehyde or some harmful things in this room, and only by opening the window can these harmful things be released.

Seven or eight hours a day to maintain ventilation time on it, do not need to ventilate 24 hours a day, generally after the decoration of ventilation for about a month, if the ventilation time is too long, there are some furniture or walls will crack, in case of rain and snow to remember to close the window.

Yes, because the formaldehyde smell is very strong after the decoration has just been completed, so it is necessary to open the window for ventilation for a long time to emit this smell.

During this time, when encountering wet weather, the wallpaper is prone to blistering. Moreover, the latex paint is sprayed, and it will not dry completely in a short time, and it is easy to affect the quality of the paint when you open the window! It is recommended that you seal it for two or three days and open the window after it is completely natural drying!

You can't open the windows in the morning or evening in winter. Because the temperature is low and the wind is strong, the cold wind blowing on the freshly made ceiling and background wall, including the latex paint wall, will dry faster for a long time, and cracks will easily appear. Personally, it is recommended to open the windows by one-third during the day to effectively communicate with the air and control the air ingress.

When the windows are opened for ventilation, dust can easily come in. We must take precautions in advance. Otherwise, it will be troublesome to clean it later.

Before opening the window, spread plastic sheeting on furniture such as cloth sofas and beds, and it will be much easier to clean later.

Without a protective net, with the windows open every day, it is easy to get into Paris mosquitoes. These flying critters cover the roof or walls and come out at night. Not only does it affect the aesthetics of the whole house, but it is also not easy to clean.

In addition to the above, we can also carry out "double ventilation". When we open the windows, we can open all the furniture, wardrobes or doors in the house, let more air into the room, and also remove the smell from the new furniture, which is really a lot of benefits! In addition, fill a basin or small bucket with cold water, add an appropriate amount of vinegar, and put it in the room, you can evaporate the moisture to protect the painted surface of the wall tower and absorb the remaining odor!

The surface of the wall can be dried after the latex paint is painted, it can be completely dried in 2 hours, and the window can be opened after drying. But in 5, especially in the cold winter, latex paint is easy to deteriorate, the adhesion is getting worse and worse, and the latex paint also begins to slowly powder. Generally speaking, latex paint that has just been renovated and does not dry completely is prone to cold.

And, over time, the walls slowly change color. Therefore, when opening the window for ventilation, it is generally necessary to control the time of opening the window when it is warmer, not too long, to prevent the wall next to the window from freezing and discoloring.

We also need to pay attention to the fact that the main doors and windows must be closed in winter in order to make the indoor temperature reach more than 5, and the style of paint should pay more attention to indoor insulation, and the windows can be opened for ventilation after the paint is fully dried. The floor of the office was renovated relatively quickly, so we went straight into the office before the walls of the office were completely dry. Due to respiration, the water vapor breathed by the human body condenses with the latex paint that is not completely dried on the wall, resulting in the problem of bubbles and mold slowly forming on the wall.

So, keep in mind that you have to wait until the latex paint is dry before you can move in.

Generally, the time for opening the window for ventilation is 20-30 minutes.

In the case of a small room, windy outdoors or colder weather, it is recommended to open the window for a short time to prevent cold; If the room is large, there is no wind or warm air outside, the window opening time can be appropriately extended. For example, in an 80-square-meter room, it takes about 20 minutes to open the window without wind or breeze.

It's not good to keep the windows open for ventilation.

The air quality is different at different times of the day, although the windows should be opened every day for ventilation in order to maintain a fresh space and improve the air quality in the house. But between 9-11 a.m. and 2-4 p.m., the air quality during these two time periods is relatively good, and it is recommended to open the windows.

The rest of the time, because of traffic congestion will produce a lot of exhaust gas, if the air quality is not very good if the window is opened, if the haze weather, the outside air quality is worse, in this case, the window will lead to a worse indoor environment, in this case, it is not recommended to open the window for ventilation.

When opening the window for ventilation, if the air volume is very small or there is no wind, it is impossible to discharge the indoor formaldehyde, so it is necessary to use electric fans, buried exhaust pipes, etc. to increase the air volume.

When the weather is getting colder and colder, that is, after the arrival of winter, people will choose not to open the window, in fact, in winter, it is more necessary to open the window to ventilate and remove formaldehyde, generally the room temperature can be raised first, and then the window ventilation effect will be better, because the boiling point of formaldehyde is low, at 19 degrees Celsius, the temperature increase is conducive to the removal of formaldehyde.

Half of the new house decoration is best to ventilate for half a year, open the window ventilation is not to keep it open, to open for a period of time and then close all the doors and windows to release formaldehyde.

The new house needs to be ventilated for more than 3 months after decoration, and the windows should be opened for ventilation to allow the air to circulate, so as to achieve the effect of removing formaldehyde.

After the renovation of the new house, it is best to ventilate it for 3-6 months. Personally, I think that it is best to decorate in spring and ventilate in summer, and stay in autumn and winter. When opening windows for ventilation, try to open all the windows to allow air convection. It is also necessary to pay attention to weather changes in time and close the windows in time when it rains.

Generally, it needs to be ventilated for about three months, because the newly renovated furniture contains formaldehyde, which is not good for human health, and should pay attention to tearing off the protective film of the furniture, the humidity and temperature of the room, preventing dust, closing the valve of electrical appliances, and often going to the new house to see it.

For ordinary people, the new house can be moved in after 2 to 3 months after the renovation is completed; When ventilating, you must open windows for ventilation, open all doors and windows to make air circulation, you can also choose the adsorption method of activated carbon, put some activated carbon indoors, and put more plants green and safe.

Generally, you can move in after about half a year. Avoid ventilation on rainy days or when strong winds, rainy days can easily cause the house to be damp, and it is easy to cause the wallpaper to be soaked.

The time period for ventilation of the new house just after the decoration: In fact, if your new house is renovated and there is natural ventilation immediately, then it will generally only take 2 to 3 months to move in. Because there is also a lot of indoor formaldehyde after the house is renovated, and this toxic substance will harm everyone's physical and mental health, and then lead to respiratory system, sepsis and other diseases, so even if you do a good job of natural ventilation, you need to put it for 2 to 3 months before moving in.

Precautions when ventilating: There are some room types that have a very good layout, they can complete the north and south ventilation, and the house has strong convection wind. We want to ventilate such a house, so that the windows can be opened, so that the wind can blow the gas in the house to the outside, and we can also bring the outside air into the room.

This results in good ventilation.

In some houses, the windows are small, or because the windows are reasonably arranged, they are not very resistant to gout. For such a house, you can also buy back multiple industrial fans with strong output power. We can plug in the industrial fan and then let the fan blow at the window, so that some of the indoor environmental pollution vapor can be blown outdoors.

At present, the vast majority of community owners will adopt that kind of ventilation method, in the summer situation, they will place a lot of industrial fans in the house, so that the powerful industrial fan can reasonably blow some harmful substances into the outdoors. Grasp the window ventilation time Many people have been opening the windows early in the morning in the process of opening the windows for ventilation and ventilation in the new house, in fact, it is not necessary at all, because the temperature in the house has not yet reached the maximum, the indoor formaldehyde evaporation is also very small.

The most effective ventilation time is actually concentrated in the time range from noon to 3 o'clock in the evening, at this moment the temperature in the room is high, the amount of formaldehyde released is large, and a large part of it can be discharged by opening the window for ventilation and ventilation. Generating air convection, as we all know, opening windows for ventilation in a new house is actually a method of air convection, which ensures that the air pollution is removed and fresh air comes in. Therefore, in the process of opening windows for ventilation, we must remember to open the relative windows, so that the gas can produce heat convection, so that the indoor formaldehyde chemicals contained in the indoor environment can be reasonably removed, which has a cleaning effect.

When the external gas is poor, there is no need to ventilate the window and open the window to ventilate the ventilation is to let the external gas in, but due to the rapid development of modernization, it is necessary to observe the external gas natural environment in advance when opening the window for ventilation and ventilation, if it is a variety of smoke and pollution source gases, it is best not to open the window for ventilation, in order to prevent digestion and absorption of a large number of gases containing environmental pollutants into it, endangering physical and mental health.
