Formaldehyde 0 08 can pregnant women live, can formaldehyde 0 8 stay

The content is still relatively small, and pregnant women should also pay attention to ventilation on time every day if they live, so as to dilute the content of formaldehyde.

The indoor environmental pollution control standard for civil construction projects GB 50325-2020 is jointly issued by the Ministry of Housing and Urban-Rural Development and the State Administration for Market Regulation

Indoor Environmental Pollution Control Standard for Civil Construction Projects (GB 50325-2020 Standard Construction Engineering): Formaldehyde; Benzene; tvoc≤；Toluene; Xylene; Ammonia; Radon 150bq m ; Suitable for: residential, hospital, senior buildings, kindergartens, school classrooms, etc.

Indoor Environmental Pollution Control Standard for Civil Construction Projects (GB 50325-2020 Standard Construction Engineering): Formaldehyde; Benzene; tvoc≤；Toluene; Xylene; Ammonia; Radon 150bq m ; Suitable for: offices, shops, hotels, cultural and entertainment venues, libraries, stadiums, public places, etc.

According to the regulations, formaldehyde in class buildings should be less than, which obviously has not yet reached the standard.

Formaldehyde is not allowed to stay in Haochang. Indoor formaldehyde concentration is required to be less than or equal to milligrams per cubic meter, and volatile formaldehyde tips:

1. Open the door at night and let the air in the bedroom exchange with the air circulation of the whole house, which plays a role in reducing the concentration of formaldehyde in the air in the bedroom.

2. It is best to move furniture and other items with particularly serious formaldehyde emission out of the house.

3. Open the wardrobe and other cabinet doors and drawers during the day for ventilation and burial, strengthen air circulation, and exchange indoor and outdoor air.

4. When resting at night, close the wardrobe door drawer, and some activated carbon can be placed inside.

to adsorb formaldehyde released into the cabinet.

Formaldehyde is an organic chemical that can be made from methanol.

It is prepared by dehydrogenation or oxidation catalyzed by metals such as silver and copper, and can also be separated from the oxidation products of hydrocarbons. Can be used as a phenolic resin.

Urea-formaldehyde resin, vinylon, melotropine.

Raw materials for pentaerythritol, dyes, pesticides, disinfectants, etc. Industrial formaldehyde solution generally contains 37% formaldehyde and 15% methanol, which is used as a polymerization inhibitor with a boiling point of 101.

The national standard is that it has been seriously exceeded, and it must be treated in a timely manner, because the release life of formaldehyde is relatively long, and the release life of some materials can even reach 3 to 15 years, and it cannot be completely removed in a short time.

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.

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

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. If you want to eliminate formaldehyde in the house as soon as possible, you can put a floor fan at home after the decoration is completed, and open the window for ventilation at the same time.

6. We all know that formaldehyde is volatile at high temperature, and we can use some heating equipment to increase the temperature at home a lot, so that a large amount of formaldehyde gas can be volatilized, and then formaldehyde can be removed by opening windows for ventilation. Repeated operation a few times, you can remove most of the formaldehyde in the home, but we must pay attention to safety when using heating equipment to avoid fire

If the formaldehyde content per cubic meter in the air exceeds the milligram, it proves that formaldehyde has exceeded the safe range, at this time we must pay attention to it, formaldehyde problem should not be underestimated, if you live in an environment where formaldehyde exceeds the standard for a long time, it will be harmful to human health, the following is for you to introduce some methods of removing aldehyde, I hope you will adopt.

1.Open all doors and windows to promote air circulation, so that harmful gases can be discharged to the outside through the flow of air, which is simple and effective. However, this method should be used to maintain ventilation for a long time, and a large fan can also be used to enhance the wind and assist in ventilation.

In this cycle, forced ventilation for a month, the odor in the room will be greatly reduced. For some movable furniture, try to place vents so that odors can be discharged directly to the outside.

2.Plants such as green plants, aloe vera, cacti, pothos and other plants have a certain absorption capacity for formaldehyde, and can slowly consume the surrounding formaldehyde through photosynthesis. 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 has the function of adsorbing formaldehyde and other harmful substances, but activated carbon does not have the function of decomposition, so the adsorption capacity is limited, easy to saturate, and needs to be replaced frequently, otherwise it will become a new pollution source to emit harmful substances to the outside, resulting in indoor secondary pollution.

4.The fresh air system is a system that filters the outdoor air and transports it to the room through the pipeline, and discharges the harmful substances contained in the room from the corresponding pipeline.

5.From the point of view of principle and effect, the formaldehyde removal company has the irreplaceable advantages of traditional formaldehyde removal methods in the treatment of decoration pollution, but now the formaldehyde removal company is blooming everywhere, it is difficult for us to judge whether the formaldehyde removal company on the market is formal, whether the product effect, service, after-sales and other aspects are perfect, when choosing the formaldehyde removal company, it is recommended to choose a more qualified aldehyde removal agency.

In summary, after the decoration of the new house, the release of formaldehyde is large, the release time is long, and the treatment of formaldehyde by a single method will inevitably be a little difficult.

Expectant mothers can move in to the formaldehyde test of the new house. . .

In China's residential air, the maximum allowable concentration of formaldehyde is 0 08 milligrams cubic meters (0 08 mg m3). Because your new house does not exceed the national indoor standards, it is completely ready to move in.

National Standard (Quality Supervision Bureau Standard Milligram) (Health Bureau Standard Milligram) (European Standard Milligram) If this standard is exceeded, it should not be able to live.

If it exceeds this standard, it is necessary to wait for the indoor formaldehyde to disappear (open the doors and windows) to meet the standard before living in people, otherwise it will be harmful to the human body, especially children.

Many people have had this experience, and new homes will have a pungent smell in the winter and a choking smell in the summer. In fact, this is related to the release characteristics of formaldehyde. Formaldehyde is one of the main raw materials for decoration adhesives.

Studies have shown that the rate of formaldehyde release hidden in furniture, floors, walls, wallpaper is directly proportional to the increase in temperature and humidity. In winter, the temperature in the heating room is relatively high and the ventilation is poor, so you can smell a pungent smell. In summer, there is plenty of rain, high air humidity, and relatively high indoor temperature, so indoor air pollution is also very serious in summer.

Spring is coming, the weather is warmer in spring, and the formaldehyde release cycle is slowing down, which is the time to prevent problems before they happen. Therefore, after the spring decoration, we must do a good job of removing formaldehyde, and do a good job of removing formaldehyde in the spring.
