Is it normal to have a formaldehyde content of 0 2 at home? Does it matter if a child moves in?

If it exceeds the standard, you can improve it according to the three steps of air purification in the new home: Step 1: open the window for ventilation.

The decoration has just ended, the smell of the new house is serious, and the pollution must be several times, or even dozens of times exceeded, so the initial one to two weeks, what means do not play a big role, the best way is to open the window for a long time to ventilate, through air convection, the pollutants in the indoor air are discharged to the outside. It can also be assisted by an electric fan to accelerate the convection of indoor and outdoor air. Step 2:

Activated carbon for air purification is used. After effective ventilation, indoor air pollution has been greatly reduced, so the focus should be shifted to solving the source of indoor pollutant release, so as to ensure continuous purification of harmful gases. Step 3:

Plant decontamination is used. Indoor suitable planting of flower plants are: spider plant (including orchid grass), cactus (cactus family), aloe vera, etc., such plants have a certain purifying effect.

Short-term exposure has little effect on the body, but excessive formaldehyde must be treated before you can move in. Especially if there are children at home, because children are more susceptible to formaldehyde, it is recommended to treat it as soon as possible. Here are several practical and effective ways to remove formaldehyde for your reference.

1. Wise Stone.

It is a purification product favored by decoration families in recent years, compared with other formaldehyde removal products, its own pores are more, with the dual function of absorption and decomposition, and the speed of formaldehyde removal is also fast. Its unique decomposition function can save the time of drying, and it is more convenient to use, which can effectively control the formaldehyde problem for a long time. When choosing, it is important to note that it is a gray ore with an irregular shape and is not a round particle

2. Open windows for 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. Plants.

Choose plants that can adsorb formaldehyde, pothos, aloe vera, spider plant and other plants can adsorb a certain amount of 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.

4. Formaldehyde remover.

Formaldehyde scavenger is the use of chemical or biological principles, formaldehyde decomposition into harmless carbon dioxide and water or other harmless substances, so as to achieve the purpose of purifying formaldehyde, but there are many manufacturers, the quality is also uneven, you must keep your eyes open when buying, otherwise it is easy to cause the introduction of other harmful substances.

Fifth, the fresh air system.

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 outside to achieve the effect of removing formaldehyde.

Formaldehyde in indoor decoration pollution is mainly in indoor decoration materials, of which harmful substances account for a large proportion of latex paint, paint, wallpaper and other wall coatings, so it is very important to deal with formaldehyde from the source.

You can go to the hospital to check whether there is any abnormality in the blood routine biochemistry, generally it is mainly necessary to judge whether there is poisoning according to the symptoms, and see if there is carbon dioxide binding in acidosis, whether there are changes in liver and kidney function, and if necessary, whether there is hypoxemia in arterial blood gas analysis.

Because acute formaldehyde poisoning is a systemic disease caused by exposure to high concentrations of formaldehyde vapor, mainly eye and respiratory damage. In addition to blood tests, chest X-rays can also be done, and it is recommended to go to a professional occupational disease hospital for examination.

At the same time, it is recommended to do Down's screening, by sampling the serum of pregnant women, to detect the concentration of alpha-fetal protein, chorionic gonadotropin and free estriol in the maternal serum, and combined with the expected date of delivery, weight, age and gestational age at the time of blood collection, etc., to calculate the risk factor of giving birth to a fetus with birth defects.

After the house is renovated, the indoor formaldehyde content must be lower before you can move in, but because the decoration of many families is too complicated, excessive formaldehyde content has become a common thing. If you want to avoid the harm of formaldehyde, the following methods can be good choices.

1. The most common way to remove formaldehyde indoors is to open windows for ventilation, and this method has almost no simple cost. However, 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 the state of constantly releasing limb sensitive pants, and it is impossible to completely remove formaldehyde through open window ventilation, it can only play an auxiliary role in removing formaldehyde.

2. Activated carbon is a traditional physical adsorption material, which has been well received in the treatment of indoor and outdoor pollution, its specific surface area is large, and it has a strong adsorption capacity, but its adsorption capacity is limited, and it does not have the function of decomposition.

<>5. The fresh air system can ensure that the home is in a ventilated state for 24 hours, which can greatly increase the exchange of indoor air and the outside world

It is not recommended because formaldehyde is more harmful to children. Save a little money and suffer a big loss. If you have to live in this house, first find out the source of the pollution.

If it's a cabinet bed, throw it away, or let it dry for a few months and look at it again. If it's floors and walls, shovel them off as soon as possible. After the pollution source is treated, formaldehyde can be quickly dispersed through ventilation, and the whole family is healthy.

Less than milligram cubic meters. gb/t18883-2002。Close doors and windows for at least 4 hours before sampling.

The average concentration should be sampled continuously for at least 18 hours, the 8-hour average concentration for at least 6 hours, and the 1-hour average concentration for at least 45 minutes. GB50325 stipulates that the acceptance of indoor environmental quality of civil construction projects shall be carried out at least 7 days after the completion of the project or before the project is put into use. Because the maintenance period of paint is generally 7 days, it is emphasized that the acceptance of indoor environmental quality should be carried out at least 7 days after the completion of the project.

When detecting the concentration of free formaldehyde, benzene, ammonia and total volatile organic compounds (TVOC) in the indoor environment, the fully decorated residential project with ** air conditioning should be carried out under the condition of normal operation of air conditioning; For civil construction projects with natural ventilation, the test should be carried out 1 hour after the doors and windows are closed; When detecting the radon concentration and rigidity of the indoor environment, the fully decorated residential project with the best air conditioning should be carried out under the condition of normal operation of the air conditioner; Naturally ventilated civil fully furnished residential works should be carried out 24 hours after the doors and windows outside the room are closed.

Method 1:

The window ventilation method is conducive to indoor air circulation and effectively disperses indoor formaldehyde.

Method 2:

Water absorption method: Put a few pots of water in the renovated house, put vinegar, green onions, and orange peel.

Wait. Evaporation in water protects the surface of the coating on the top of the wall, while absorbing the residual formaldehyde odor in the room. Just change the water twice a day.

Method 3:

The most common methods of plant purification are aloe vera, spider plant, and wild lily.

Wait. They can remove harmful substances from the air, especially formaldehyde.

Method 4:

Activated carbon. Adsorption method. At present, activated carbon is recognized as the "nemesis of formaldehyde".

Activated carbon can remove dust, sterilize, purify the air, absorb harmful gases, and at the same time keep the room dry. It can be kept at home for a long time. At present, activated carbon is widely used in home decoration.

After the activated carbon is saturated, remember to expose it to the sun to help make full use of it again.

Babies can't stay; The formaldehyde concentration in the air can only be stopped when it reaches less than one cubic meter; If you want to remove formaldehyde, you can often open windows for ventilation, and you can also put some green plants in your home that are clean and resistant to air.

If formaldehyde is also not allowed to live, the best way is to ventilate or put some adsorption carbon or some green plants in the room in the fiberstone.

is not able to live; You can put some green plants in the house, you can also open windows for ventilation, and you can also put some activated carbon.
