Open the window to move in, is not afraid of formaldehyde?

No, although opening windows for ventilation is indeed effective, it can only remove the smell and formaldehyde left over from the decoration.

Formaldehyde is very harmful to the human body, and long-term inhalation of formaldehyde will increase the risk of cancer.

chances. However, when we decorate the house, many materials contain formaldehyde, which is the reason why the newly renovated house cannot be inhabited, and formaldehyde needs to be slowly volatilized.

The volatilization period of formaldehyde is as long as 3 to 15 years, that is, even if the temporary formaldehyde is removed, if no effective formaldehyde removal method is taken when living, it is very likely to induce leukemia.

Speed up the way to remove formaldehyde

Governance Approach. 1. Ventilation method: the largest amount of pollution released after the decoration has just ended, at this time, the effect of what deodorant is not much better, the best way is to open the window for ventilation. After the renovation of the new house is completed, it must be ventilated every day.

2. Plant method: Indoor proper cultivation of some spider plants.

and other green plants.

3. Activated carbon.

Method: It can adsorb harmful substances, but don't think that with activated carbon, your home will be tasteless immediately. Activated charcoal lasts from 3 to 6 months, after which it becomes saturated and becomes inactive.

It is recommended to place some nano live ores at the same time for adsorption, which can effectively decompose harmful gases such as formaldehyde and benzene.

Fourth, photocatalysts.

Method: The photocatalyst is anatase titanium dioxide.

The photocatalyst activated by visible light can continuously decompose the formaldehyde in the furniture in the air where there is light, and has a long-term lasting effect, which can reach 5 years, and is not toxic in itself, which is the most popular and greenest formaldehyde removal method.

5. Plant-derived purification method: plant-derived air purifies terpenoids.

It has a wide range of biological activities, but relies on the traditional production methods of plant bodies.

It is one of the bottlenecks in the promotion of applications. The use of synthetic biology strategies to create microbial "cell factories" is expected to provide advanced technology for the low-cost and sustainable supply of plant-derived terpenoids.

6. Physical adsorption method:

Physical adsorption to remove formaldehyde is not like chemical sprays.

It itself is safe and does not have to worry about the problem of secondary pollution, the commonly used adsorption materials are carbon bag and algae na, sufficient use can play a good role in purification, but the charcoal bag should remember to dry and replace regularly, so as not to absorb saturation, although algae can decompose formaldehyde, no need to dry, but try to avoid touching water, so as not to affect the purification effect.

The above content refers to Encyclopedia - Formaldehyde Pollution.

In addition to formaldehyde is to pay attention to the method, choose the right method, the work of removing aldehyde will be much faster, but can not be blindly chosen, now there is too much false information on the market, choose the wrong method, aldehyde removal is not timely, will damage people's health, the following is for you to introduce several methods of removing aldehyde, so that you can easily and quickly remove formaldehyde.

1. Green plants. Plants are the best products provided by nature to remove formaldehyde, and the more respected ones on the market are: pothos, spider plant, ivy, and aloe vera. These plants are a combination of beauty and talent, both to decorate the home and to purify the air.

2. Ventilation. Open the window ventilation is the best way to remove free formaldehyde, when the window is opened, there will be a steady stream of fresh air will 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 when used.

3. Muguang blue.

It is a more excellent formaldehyde removal product than photocatalyst, which can quickly penetrate into the inside of the pollution source after spraying, and will take 3-15 years to volatilize the formaldehyde at one time, and then decompose into harmless carbon dioxide and water.

4. Arrowstone. Ruishi is a pure natural ore, with regular honeycomb voids inside, its specific area is huge, can efficiently adsorb formaldehyde, its adsorption capacity is strong, can reach more than 20 times of the traditional activated carbon, not only adsorption capacity, but also has ion exchange function, can decompose formaldehyde and other harmful substances into harmless carbon dioxide and water, without replacement can be used for a long time.

5. 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.

6. Air purifier.

There are many brands of air purifiers, mixed with fish and dragons, ordinary air purifiers do not have a good effect of removing formaldehyde, when purchasing, we should look for products with formaldehyde removal function, you get what you pay for, and it is not recommended to buy less than 1000 yuan when purchasing.

The formaldehyde in the new house exceeds the standard, and it cannot be moved in immediately after ventilation. Ventilation has limited formaldehyde removal capacity, slower speed, and a longer formaldehyde release period, which is 3-15 years.

Therefore, the ventilation work needs to be continuous and uninterrupted, and it is not enough to solve the problem by ventilation for a few months.

In the process of decorating a new house, the decoration materials such as paint, coatings, wood boards, plywood, etc. will be used. They contain different degrees of harmful gases such as ammonia, formaldehyde, ethylene, benzene, and methanol. After the renovation of the new house is shelved for a period of time, the toxic substances in the house are blown out of the house by the wind, although the owner can not smell the smell, but in fact it is not exhausted, and there are still toxic substances left in the decoration objects.

Generally, family windows are designed at a position of more than one meter above the ground, and the density of formaldehyde is higher than that of air, and it is easy to precipitate. In addition, most hazardous substances are released slowly, up to 3 to 15 years. Hot summers and heating in winter are usually the peak periods for formaldehyde emissions, which are 20 to 30 percent higher than usual.

Therefore, if the formaldehyde in the house exceeds the standard seriously, it is useless to rely on ventilation for a few months, and the key is to ensure that the pollutants do not exceed the standard and the indoor air quality is qualified. Formaldehyde is the main pollutant in the new home, these pollutants come from the home decoration materials, the formaldehyde content in the air at home mainly depends on whether the decoration materials are environmentally friendly, and the length of ventilation time is not directly related.

If the ventilation conditions are good, 5-6 months is the best time to move in. During this time period, the house has experienced at least two seasons, and the relatively high temperature in summer can accelerate the volatilization of harmful substances such as formaldehyde.

Families with pregnant women, the elderly and children need to pay special attention, the resistance of this group of people is very low, especially in the case of formaldehyde without windows and no ventilation, it is recommended not to rush to move in. If you have to live in a hurry, you also need to find a scientific and effective way to govern it, and consider moving in after reaching the standard.

The most effective way to remove formaldehyde scientifically is [strengthen ventilation].

In addition to formaldehyde can not rely on ventilation alone, but must not be ventilated, through is the basic work, must be maintained, but also can cooperate with the fan to accelerate indoor air circulation, for accelerating the smell of great help, especially some ventilation conditions are not very good house type, can play a very obvious effect.

The most effective method to remove formaldehyde scientifically is [decomposition of formaldehyde].

Baizao Na is currently favored by treatment engineers, not only because the adsorption and purification speed of Baizao Na is faster, the most important thing is that it can decompose formaldehyde, not just simple adsorption, the carbon bag must be dried and replaced after absorbing a certain amount, or there will be adsorption saturation, and Baizao Na is adsorption plus decomposition, so there is no need to dry, and there is no need to worry about the problem of adsorption saturation, it will be more suitable for urgent living, and it is more convenient to use.

The most effective way to remove formaldehyde scientifically is three: [wipe furniture].

Salt water wiping the surface of furniture has always been our more advocative method of assisting in removing furniture odor, the harmful gases in the furniture are slowly released through the furniture surface plate, formaldehyde is soluble in salt water, wiping with salt water can take away some of the harmful substances attached to the surface of the furniture, and it can also play a good role in removing odor.

The most effective method to remove formaldehyde scientifically is four: [green plant purification].

Placing green plants in the new house can not only purify the air, but also beautify the indoor environment, most people will do this, but the green plants are particular, not all plants can purify the air, the effect is better: pothos, spider plant, tiger orchid and yew, these green plants are suitable, the effect is also better, and it is also a good choice to place some in the new home.

If the formaldehyde exceeds the standard, you can't live in it even if you open the window. It is necessary to open the window for ventilation for a certain period of time, and the formaldehyde does not exceed the standard before you can live.

It is best not to live in a house with formaldehyde, because formaldehyde will harm your health.

You can put an electric fan or something in the house, and completely remove the formaldehyde before moving in.

Formaldehyde in furniture is released slowly, although the window can be opened, but formaldehyde still exists. It is best to ventilate for a few months before going to live.

Newly renovated house, there is more formaldehyde, you must open the window for ventilation, at least more than half a year to live, put a few more pots indoors, put some salt water in it, change it once every three or four days, this most common method is very applicable.

No. Because formaldehyde is in the house, you will definitely be exposed to it. It can only be said that dilution and release of formaldehyde can not completely remove anything, and fundamentally solve any problem.

If it's an adult, it doesn't matter, it's generally bearable, if there are pregnant women and children, how careful it is not too much, it is recommended to go out to live, find a third party to test and don't live in a new house, that qualified is only relatively adult, and children are sick too much.

In a house with formaldehyde, the minimum ventilation of the window can be lived in for three months to half a year, and it is best to put some bamboo charcoal when the window is opened for ventilation.

It is recommended that pregnant people do not live, and it is recommended to wait until it is cleared before living. The specific methods are: 1. First of all, it is necessary to keep the room fully ventilated 2. Place plants that can absorb harmful gases indoors.

3. If you want to take effect quickly, it is recommended to use commercially available deodorant sprays, and it is best to use products that have been certified by authority.

It is possible to open the window during the day, and it is operated normally. If you don't open the window at night, it won't work, and it will be more or less harmful to the human body.

There are a lot of these harmful substances in the new house. It is best to leave it for a while, and you can put some plants indoors.

There is formaldehyde house, indicating that it is a newly renovated house, because the decoration materials contain formaldehyde, so formaldehyde gas is volatile all the time, although the window is open, it can not live in people, otherwise it will be harmful to the body.

There is formaldehyde, it takes a while to open the window for ventilation, don't get sick because of early check-in.

It is best to open the windows for ventilation, and thoroughly exude the re-residence, which is really helping you look forward to adoption

After the house is renovated, if the formaldehyde in the house exceeds the standard, then the windows are not open and you can't live in, and you must release the methanol before you can move in. If it only contains methanol, then methanol should also be used. You can only stay after the release, which is better for the body.

Opening windows for ventilation is the best way to remove formaldehyde! But if there is formaldehyde in the house, although you are sleeping with the window open, formaldehyde will definitely still be in this room, and you will still inhale formaldehyde when you breathe! So it's best not to sleep in this kind of room, even if the windows are open, it's better to wait until the ventilation is out before living in this house!

If there are special circumstances, it is okay to stay for a few days once in a while, but if you have very young children with you, it is definitely not okay!

Of course, it is not allowed to move in, the newly renovated house is generally heavier formaldehyde, if there are pregnant women who need to stay, they need to be careful, pregnant women's resistance is relatively weak, if you live in a room full of formaldehyde, it will cause great harm to the fetus, if there are pregnant women at home, it is recommended to carry out formaldehyde testing and treatment before moving in.

In recent years, there have been frequent cases of indoor formaldehyde hazards, many children living in places with a lot of formaldehyde will be nauseated, retching, dizzy, long-term formaldehyde exceeds the standard of the indoor and even leukemia and other blood diseases, the body is very lethal.

If the indoor formaldehyde exceeds the standard, or if the new house has just been renovated, pregnant women who want to move in must be resolutely stopped, and do not ignore the healthy growth of the fetus because of impulse.

Today's decoration materials, especially the use of glue or a lot of wood products, are also used glue for bonding or adhesion, which will emit a lot of formaldehyde, or will cause bad effects.

Yes, if you open the window, there will still be residue, and it is best to ventilate for more than half a year and then live better.

Can you live in a house with formaldehyde open the window? Don't live in a newly renovated house, there is a very strong formaldehyde in it, you must put it for more than half a year before you can move in, open the window for ventilation for more than half a year, and the formaldehyde can be released.

Open the window to move in, not afraid of formaldehyde. Opening windows for ventilation can remove formaldehyde, but it cannot remove all formaldehyde, because opening windows can only promote air circulation and accelerate the exchange of indoor and outdoor air. The divergence time of formaldehyde is 3 to 15 years, so you are not afraid of formaldehyde when you open the window and move in.

Too much formaldehyde can easily lead to ** allergies, so you must take measures to remove formaldehyde before you can move in. Using the power of science to remove formaldehyde in the room, we can install a ventilation system in the room, or place an air purifier, which can purify the indoor air and remove the formaldehyde in the room at the same time. The downside is that it may cost some money.

Formaldehyde production technology

Since 1888, Germany first realized the industrial production of formaldehyde, and the production methods of formaldehyde have appeared according to the different raw materials, such as liquefied petroleum gas.

Non-catalytic oxidation of raw materials, dimethyl ether oxidation, methane.

Oxidation, methanol.

Air oxidation.

In 1923, after the German BASF company realized the large-scale production of methanol from syngas, the large-scale production of industrial formaldehyde had a good raw material base, and the methanol air oxidation method became the most commonly used method for the production of industrial formaldehyde.

As of 2010, more than 90% of the formaldehyde produced in industry is made from methanol as raw material, using methanol air oxidation method. Methanol air oxidation method is divided into methanol excess oxidation method, air excess oxidation method, later, in order to prepare high concentration of formaldehyde and improve the comprehensive utilization efficiency of energy, and successively developed tail gas circulation method, formaldehyde oxidation method, etc.
