The new house has been ventilated for 3 months, and the formaldehyde is still exceeded?

When you can move in after the renovation of the new house cannot simply look at the length of time. After the decoration is completed, it is best to carry out a decoration pollution test, if the indoor air standard is up to standard after decoration, you can move in immediately; If the indoor air quality is still not up to standard after the house is renovated, it should be treated first to ensure that the living is clean and environmentally friendly.

Generally speaking, formaldehyde is released slowly, the release period is 3-15 years, and the formaldehyde is still exceeding the standard if the ventilation is 3 months. It is recommended that you take care of it for your own health first

1. Long-term ventilation should be carried out. Through the flow of air, the harmful gases will be channeled outdoors. But ventilation is slow, and newly renovated houses generally take 3 years.

2. You can put a few more potted plants such as spider plant, agave, etc., so that they can absorb formaldehyde, but this method is also slow.

3. You can use some physical means to put some activated carbon, nano live ores, etc. indoors, and their adsorption is relatively good. Formaldehyde can be absorbed, but activated carbon has a saturation and cannot be absorbed for a long time.

4. You can use some chemical methods. However, if you use chemical reagents, some of them will cause secondary pollution, which will also harm furniture or something.

5. You can also use more environmentally friendly ones, such as herbal Diarin, which is safer and more thorough to remove. After removal, close the doors and windows for 24 hours and open the ventilation, spray back and forth a few times, you can pass the 3-day ventilation period, and then test it to see if it is up to standard, and you can move in if it meets the standard. I also think the same as my colleague, recommend the use of herbal dia(ya) forest and hope to help you!

Formaldehyde can be treated well, so that you can move in with peace of mind.

Formaldehyde in new houses exceeds the standard, and you need to find a formal formaldehyde removal company to test it. Here it is suggested that you can find Foshan City Love Space Environmental Protection. "Love Space" is aimed at air purification and comprehensive treatment of indoor environment, car environment, public places and other places.

After the renovation of the new home, many people do not know whether the formaldehyde exceeds the standard, and love space can provide door-to-door testing services. Specific detection methods and over-standard treatment can be consulted Mr. Zhu,**:18169820181

That's right, as long as the ventilation of the new house takes half a year, you don't have to worry about excessive formaldehyde when you move in, and you can test it again if you are really worried.

After the decoration of the new house, it is very necessary to ventilate and dry for half a year, and before moving in, special staff should be hired to check the formaldehyde content. Or find a professional construction person for adsorption.

It's not like that, but you should put some activated charcoal in the corner of the room to absorb these toxic gases.

So what does it mean for us to talk about ventilation for half a year? Those free formaldehyde, free TVOC, free benzene, free toluene, xylene, and free ammonia, its release rate is relatively fast in half a year. But will it be safe to move in after it is released?

The answer is no, why?

First, whether you can move in must pass the scientific test, it must be lower than the national mandatory standard 50325, lower than its maximum limit before you can move in. Second, if I don't test it based on experience, it doesn't work, because free formaldehyde, free benzene, free TVOC, free ammonia, free xylene, these things generally have to volatilize for 1-3 years before they can be volatilized cleanly. Especially when it uses the board of this furniture, the board of decoration, the quality can not be guaranteed, or the owner does not understand it, it is very troublesome.

So we couldn't stay in it. From the experience of the person, you can't stay, if you must want to stay, you have to go for a test. What should I do if I can't do it after testing? Then you need to do an internal cleaning, that is, the whole house is detoxified.

What are the basic principles of ventilation?

The ventilation method is to open the window, let the outdoor fresh air blow into the room, and squeeze the indoor formaldehyde-containing polluting gas to the outside, so that the indoor and outdoor air can be replaced, the indoor formaldehyde content is reduced, and the indoor air is purified.

Why can't ventilation alone remove formaldehyde?

When ventilated, the formaldehyde in the indoor air can indeed be quickly discharged to the outdoors, but the formaldehyde is constantly released from the furniture, once the window can not be opened when sleeping or bad weather, formaldehyde will accumulate and exceed the standard, so the ventilation method can not completely solve the formaldehyde problem.

It is necessary to remove formaldehyde in the decoration of new houses, but we must not only rely on ventilation to remove formaldehyde, but also to avoid some wrong methods.

Correct method 1: Wipe the furniture with salt water

The wood paint on the surface of the furniture plate and the surface is the main odor of the furniture, and the toxic and harmful substances such as formaldehyde are released into the indoor air through the surface of the furnitureWiping the surface of furniture with mild salt water can take away the harmful substances attached to the surface of furniture, and regular wiping can reduce the release and emission of furniture pollutants, and it is also good for removing furniture odors.

Correct method 2: decompose particles for purification

Adsorption + decomposition of this kind of material, I believe everyone is no stranger, algae can beIt decomposes formaldehyde, and it is still sun-free, so it is very convenient for most people to keep it at home.

Correct method three: penetrate the interior of the furniture

Furniture, curtains, wallpaper, flooring, wooden doors, etc., these are important for odor and pollution in the homeIt is osmotic purification, which can penetrate deep into the interior of furniture panels for formaldehyde decomposition, which can further accelerate purification.

Correct method 4: carbon bag adsorption of formaldehyde

Carbon bag is a familiar and commonly used purification material, it can adsorb formaldehyde and other harmful gases, so as to play a role in purification, but it will also be saturated,It is recommended that it must be dried once a month or so, and replaced about half a year to avoid secondary pollution caused by adsorption saturation.
