The formaldehyde test is qualified, why does the house still have to be dried for three months to li

For the sake of safety, there may be other toxic gases in addition to formaldehyde in decoration materials, which can diffuse the gas in three months and reduce the harm to the human body.

Passing the formaldehyde test means that the formaldehyde does not exceed the standard, and does not mean that there is no formaldehyde. Ventilation and drying for three months is still more guaranteed for personal safety.

Because it is necessary to dredge the air, the house has just been renovated, even if the formaldehyde is qualified, it is still not suitable for living inside, and it is more suitable to cool it after three months.

The formaldehyde test is qualified, which does not mean that there is no formaldehyde in the house, and the formaldehyde is all volatilized in the air for three months.

Because different home decorations and building materials are different, the amount and emission of harmful gases such as diformaldehyde and benzene contained in them are not the same. So there is no standard answer to the check-in time of a new home.

The formaldehyde test is qualified, but the formaldehyde in the air is qualified, and the material may still contain formaldehyde, which has not yet been emitted, and it is safer to dry it for three months.

It is said that the new house can not be lived in immediately after decoration, it will contain toxic substances, although the formaldehyde test is qualified, but it is not suitable for immediate living, and more drying is good for health.

The formaldehyde test is qualified, and it can only be said that the amount of formaldehyde contained in the house is lower than a certain standard, but it cannot be said that there is no more, so in order to live more safely, it needs to be dried for a period of time.

The formaldehyde test only means that the formaldehyde content in the house does not exceed the standard, but the formaldehyde component is still there, and it will not harm health after ventilation.

Because formaldehyde is qualified does not mean that there is no more, and formaldehyde is qualified, sometimes it will still threaten human health, so it is better to leave it for a period of time.

After the renovation of the new house, it needs to be ventilated and dried for more than 3-6 months before moving in;

According to China's housing air standard, the maximum allowable concentration of formaldehyde is (0 08mg m3).

Because there is a formaldehyde smell after the decoration of the new house, which is harmful to health, the new house needs to be placed more after the decoration of the house.

It takes 3-6 months. And in 3-6 months, it is necessary to open the windows during the day and close them at night to maintain the ventilation of the newly renovated house.

If you move in as soon as possible, it is recommended to take the following measures to remediate:

1. Physical removal of formaldehyde.

Activated carbon is a kind of physical adsorption, like activated carbon, nano live ore, bamboo charcoal, which is very safe and harmless to the human body.

2. Plant removal method.

Choose and place plants according to the different functions and sizes of the room. Like aloe vera, spider plant, pothos, tiger pill orchid, one-leaf orchid, ivy and these. (Aloe vera is a very good hand at deodorizing new houses).

3. Clear water absorption method When deodorizing the new house, put a few basins of water in the new house, and put vinegar, green onions, orange peels, etc. in the water, which can not only absorb the residual odor in the room, but also protect the paint surface of the wall top by evaporation. The water absorption method for deodorization of new houses is not only simple, convenient and economical, but the water needs to be changed twice a day.

In this way, you can stay in about 2 months. (Except for infants, which require more time).

At least three months to take a formaldehyde tester to test it.

Of course, formaldehyde can be measured at any time. The easiest way is to use formaldehyde test boxes, but there may be some errors, in order to accurately detect indoor formaldehyde content, it is recommended to prepare more test boxes and calculate the average value. After introducing how to measure indoor formaldehyde concentration, let's bring you some efficient methods for removing aldehyde.

1. Wise Stone.

It is a very popular purification product on the market in recent years, the main reason is that it has the dual function of absorption and decomposition, can actively absorb free formaldehyde in the air, and does not have to worry about the influence of external factors such as temperature, humidity, light, etc. The adsorbed formaldehyde will also be decomposed into water and carbon dioxide and discharged from the body, without drying and no secondary pollution. 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 can remove formaldehyde, although formaldehyde can be removed, but the amount of formaldehyde it absorbs is very limited, and when the indoor concentration is high, if the plant alone relies on formaldehyde adsorption, the amount is very large.

3. Open windows for ventilation.

The most common way to remove formaldehyde indoors is to open windows for ventilation, and this method has almost no cost. But the ventilation method also has disadvantages, first of all, the location of the house should be good to achieve the effect of ventilation, and secondly, the formaldehyde in the decoration materials is in a state of continuous release, and it is impossible to completely remove formaldehyde through window ventilation, it can only play an auxiliary role in removing formaldehyde

Fourth, high temperature.

High temperature and drying can accelerate the volatilization of formaldehyde and other harmful substances, so you can take out drawers, movable furniture, mattresses, etc., to the balcony for ventilation and drying, and furniture that can not be dried can be fumigated at high temperature, with garment steamer, steam engine mop, high temperature steam to speed up the volatilization of formaldehyde.

5. Photocatalysts.

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.

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.

Some time ago, because my grandfather and father both had polyps on the colon, they both suspected that it was caused by formaldehyde at home. The reason for this suspicion is that the house was renovated at the beginning of the year, and it was moved in directly after the renovation without ventilation.

Summary. Generally speaking, the divergence period of formaldehyde can be as long as three to fifteen years, but the owner does not need to wait so long to move in, the volatilization period of formaldehyde is mainly fixed in the three months before and after the decoration of the house, so the owner needs to open the window often for ventilation and wait for three months before moving in. In addition, during the period of formaldehyde drying, the indoor temperature and humidity should also be controlled within a healthy and comfortable range to avoid the formaldehyde concentration rising again and failing to reach a safe level.

How long does formaldehyde dry before you can move in.

Generally speaking, the divergence period of formaldehyde can be as long as three to fifteen years, but the owner does not need to wait so long to move in, the volatilization period of formaldehyde is mainly fixed in the three months before and after the decoration of the house, so the owner needs to open the window often for ventilation and wait for three months before moving in. In addition, during the period of formaldehyde drying, the indoor temperature and humidity should also be controlled within a healthy and comfortable range to avoid the formaldehyde concentration rising again and failing to reach a safe level.

It has been more than three months since the hard-installed wardrobe was installed at home, and the bed and sofa have only been placed for more than one month.

Yes, you can also buy some activated carbon to adsorb formaldehyde.

Buying jelly to remove formaldehyde is not only ineffective.

Yes, in addition to formaldehyde jelly is also effective.

Generally speaking, how long does it take for a new house to be able to move in, there is actually no very standard answer to this topic, after all, the materials and ventilation used in the decoration of each family are different, so the time required to dry is not necessarily. We want to know whether the new house can be occupied, in fact, we have to test whether its formaldehyde residue is up to standard before we can decide, not that who stipulates a time.

In life, we often find that some people have been ventilated for a long time, but the formaldehyde still exceeds the standard, so they dare not go in to live at all. But they also feel very curious, after all, it's very bad to buy a house and not be able to live in it, but they really don't know what to do if they can't meet the standards after hanging it for so long. In particular, some families with children are afraid that it will have a bad impact on their children's health after living in, so they do not dare to live in a new house, but rent a house outside.

Many people have proposed ventilation, but the effect is not obvious, generally we have to see if it can really achieve effective ventilation. First of all, we should try to open all the doors and windows in the home, so that the indoor ventilation and convection, so that the flowing air can take away those harmful substances, as well as the odor during decoration. Including cabinets, wardrobes, shoe cabinets, etc., so that all the cabinets of the bees must be opened to allow them to ventilate the interior.

If you have poor ventilation, you can use something like a fan.

There is also the use of air purifier or fresh air system, such a machine can remove formaldehyde in a short time, and can reach more than 50%, especially pay attention to air flow, if there are conditions in the home, you can indeed try it. Many people think that plants can remove formaldehyde, but in fact, its role is not particularly obvious, so we can not rely too much on plants, it is better to use a little activated charcoal.

In the process of decorating a new house, you must choose some environmentally friendly materials. If the formaldehyde is still excessive for three years, you can't live in this house, or you should find a special formaldehyde removal company.

Generally speaking, it takes about 6 months to move in, and the formaldehyde exceeds the standard for 3 years, indicating that there is a problem with the decoration materials.

There is no specific time frame for this, but it is recommended to spend at least a month.

Friends, it is recommended to treat it, formaldehyde is not something that can be treated by drying, and the normal value cannot exceed health first.
