Formaldehyde 0 7 has lived for a year, how long can formaldehyde 0 7 live

A newly renovated house cannot be moved in immediately because a large amount of harmful substances will be generated during the renovation process. The formaldehyde content per cubic meter in the air is greater than milligrams, which means that the formaldehyde has exceeded the standard, and the test value has exceeded the standard many times, and indoor pollution may endanger our health. The following methods to remove formaldehyde hope to help you.

1. Opening windows for ventilation may be the easiest and fastest way to remove formaldehyde, but the most important premise of ventilation to remove formaldehyde is to maintain ventilation. For example, in summer and winter, when the air conditioner is turned on, the doors and windows are closed or there is no wind outside, the effect of removing formaldehyde cannot be achieved.

2. Green plants, aloe vera, cactus, pothos.

and other plants have a certain ability to absorb formaldehyde and can pass through photosynthesis.

Slowly consume the surrounding formaldehyde. 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 carbon.

It is a more effective method 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.

<>5. The release rate of formaldehyde mainly depends on two factors, one is temperature, and the other is humidity, so we can use this characteristic of formaldehyde to use heaters and humidifiers.

Let the room be in a state of high temperature and high humidity, and then we can cooperate with ventilation or adsorbent materials to absorb the formaldehyde that has been released at home, this method is mainly to treat the latent formaldehyde at home, and the effect is very good.

6. Ventilation is an indispensable method for removing formaldehyde indoors, but when the outdoor wind is not strong enough, it is necessary to strengthen ventilation. At this time, you can buy a high-power industrial fan to assist in the removal of harmful gases in the house, which can accelerate the circulation of air inside and outside the house, which is of great help to remove indoor decoration pollution

The indoor formaldehyde concentration requirement is less than or equal to milligrams per cubic meter, that is, the formaldehyde concentration in each cubic meter of air shall not exceed milligrams. Formaldehyde has always been a nightmare for new families, with more and more health accidents caused by formaldehyde, people's awareness of formaldehyde is becoming more and more intense. In fact, we can use the following methods to deal with formaldehyde in new house decoration, saving time and effort.

1. Opening the window for ventilation is the best way to remove free formaldehyde, when the window is opened, there will be a steady stream of fresh air to dilute the indoor air containing formaldehyde to achieve the purpose of purifying formaldehyde, but the window is easily affected by the weather, and the effect is also affected by the house type.

<>4. 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 inside of the plate, although the formaldehyde cannot be completely removed, but its effect is still very obvious.

5. Choose plants that can adsorb formaldehyde, such as pothos, aloe vera, spider plant and other plants can adsorb certain formaldehyde pollution, and can indeed remove formaldehyde. Placing some greenery in your new home can also help to beautify the room and freshen the air. However, the adsorption capacity of plants is relatively limited, and if the formaldehyde concentration is too high, the plants will wilt and die

Formaldehyde is a composite national standard in the past, and it does not produce much to the body, please rest assured.

This number is also really scary, so much more than the standard can not be felt? Since you find that it exceeds the standard, move out immediately and deal with it as soon as possible.

We're glad to answer your questions! Referring to my relatives, formaldehyde has lived for a year, it is very dangerous, it is excessive formaldehyde, which will make people dizzy and breathless. The state stipulates that the standard range of formaldehyde should be less than that, and if it exceeds this range, it will be excessive formaldehyde, which will make people dizzy and breathless.

Formaldehyde exceeding the standard needs to be dealt with in time, such as: placing activated carbon indoors, activated carbon can absorb indoor formaldehyde, and if it is a new house decoration, it must be ventilated for 3 months, and the formaldehyde can only be moved in after volatilization. Formaldehyde**Which items 1, the wood materials used in the decoration of the wood part contain formaldehyde, they are bonded by resin glue, so the more carpenter in the decoration, it means that the formaldehyde content is more.

Therefore, if you want to use wooden furniture for decoration, you should try to choose pure solid wood furniture, which is more material and has less formaldehyde content. 2. In addition, formaldehyde is also contained in some fabric fabrics, such as curtains, carpets, sheets, etc., because there are also resin glue components in the fabric, and formaldehyde will inevitably be found in this and some glue.

So when choosing fabric decorations, you must pay attention to see if there is a taste. 3. Construction accessories In the decoration project, the construction accessories will also have formaldehyde content, such as: wall and ground solid, as well as foam glue, structural glue, etc.

Moreover, when the wall is tiled, in order to prevent it from falling off, tile adhesive will also be added, and tile adhesive may also have formaldehyde. 4. Glass glue formaldehyde is mainly used in the decoration of Zheng Yuan, which is widely used. It is used in the decoration of glass doors and windows, bathroom cabinets, and countertops, but the glass glue also contains a lot of formaldehyde, so it is necessary to pay great attention to it when using it.

Hope mine can help you! <>

If you have any other questions, you can ask me again.

It is a serious formaldehyde exceedance, the check-in time needs to be decided according to whether the indoor formaldehyde content is qualified, the most important thing to check in quickly is to control the concentration of formaldehyde in a safe range, and how long to control formaldehyde in a safe range depends on the method used, recommend several methods to everyone, I hope to help you quickly move into a new house.

1. This is a gift from nature to us, and it is the most economical way to remove aldehyde, as long as the window is opened, fresh air will enter the room, and formaldehyde will be purified by dilution.

2. Putting some green plants at home can also effectively remove odors, especially pothos, spider plants, aloe vera, monstera, cactus, ivy, etc., which can effectively absorb harmful gases. In addition, large plants such as the Ping An tree and the camphor tree, which are more popular on the market, can release a fresh gas on their own, which makes people feel happy, and is also more suitable for removing the smell of new furniture.

3. Activated carbon to remove formaldehyde is the most commonly used way to remove formaldehyde in life, and the cost is low, but activated carbon is prone to adsorption saturation in a short period of time, and it needs to be replaced or dried after saturation. Another point to note is that if the amount of activated carbon is not enough, it will not play much role in removing formaldehyde indoors.

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.

6. The principle of the fresh air system is ventilation, the outdoor fresh air is filtered and transported to the room, and then the harmful substances containing formaldehyde are discharged outdoors to achieve the effect of removing formaldehyde

Formaldehyde is in an excess state, and how long it will take to move in depends on the loss and absorption of formaldehyde. When the formaldehyde content is reduced to the following, it is ready to move in.

Formaldehyde pollution is mainly concentrated in homes, textiles and food. Man-made boards such as plywood, fiberboard, and particleboard in living room decoration materials and furniture contain a large amount of formaldehyde-based urea-formaldehyde resin, and formaldehyde is contained in various paints and coatings. In the production and processing of textiles, formaldehyde-containing N-hydroxymethyl compounds are used as resin finishing agents to increase the elasticity of fabrics and improve wrinkleness, and formaldehyde-containing cationic resins are also used to improve dye fastness.

This one is more powerful. You have to analyze whether it is in the furniture or in the decoration. I guess it's most likely to be in the self-made cabinets and kitchen cabinets during the renovation process.

Such a concentration, even if it is ventilated for a year, can only drop by half. Therefore, if you buy your own furniture, if you have enough reasons to return it, you can't return the cabinets you made.

If you want to deal with it, give two suggestions:

The first is ventilation management. When the temperature is higher than 30 degrees, try to keep the room ventilated. In spring and autumn, the house should be ventilated as much as possible throughout the day.

When you can't ventilate the whole day, ventilate the whole house when you get up in the morning, go out and go home and go to bed at night. When ventilating, especially when the wind is strong, try to open the cabinet doors and drawers. When the doors and windows are closed and the room is not ventilated, especially when sleeping at night, the cabinet doors and drawers should be closed.

The second is adsorption. Buy diatom mud or diatom pure, buy it according to the quantity required by the manual, put it in the cupboard, take it out for a month to dry it and breathe it and then put it back. This is also capable of adsorbing formaldehyde.

You can only live if you are below, and only governance can solve it if it is so high, it is too high.
