Can I stay with a formaldehyde content of 0 247?

The release of formaldehyde is long-term, ranging from 3 to 15 years. If you just rely on ventilation, you can't quickly eliminate formaldehyde. People's traditional perception that natural ventilation can be assured of staying in 3-6 months, which is based on the solid wood furniture used in the previous decoration, and the decoration materials are single and not complicated.

Nowadays, a large number of particle boards, MDF, large curtains, floors or carpets are used in decorations. Formaldehyde is used as a fixing agent, preservative, and anti-wrinkle agent, which is widely used in the above items, and the qualitative change caused by quantitative change will eventually affect our normal stay. In addition to ventilation, the most accepted method is to remove formaldehyde, which can shorten the check-in period to 7-15 days.

Schools, hospitals, shopping malls and other places can be put into use immediately after the renovation is completed, and there is no smell of new decoration...

It is exceeded, generally in the following.

Formaldehyde national standard <= Indoor Environmental Pollution Control Code for Civil Buildings), = Indoor Air Quality Standard"), is exceeded, it is best to move in in addition to formaldehyde, it is recommended to ventilate for a month, and remove formaldehyde for tables, chairs and beds with serious formaldehyde exceedance:

1. Put some plants to absorb the taste, or spray the plant liquid Dialin can also be faster.

2. In summer, the temperature is high, and formaldehyde is released, and more ventilation can ventilate part of it.

3. Good materials to decompose, Ye Guangni uses high-end raw materials, small particle size, strong adsorption, can decompose formaldehyde inside furniture, long-term treatment.

4. After removing it, you can see if there is still a smell, and the test is finished.

Summary. Pro, formaldehyde can be occupied.

Is formaldehyde acceptable.

According to the national indoor formaldehyde content standard, the indoor standard formaldehyde content can not be higher, so if the formaldehyde content in the room is missing, it is recommended to open the windows for ventilation at ordinary times, so that the formaldehyde volatilizes to the standard content and then move in, so that the health is guaranteed.

According to the national indoor formaldehyde content standard, the indoor standard formaldehyde content can not be higher, so the indoor formaldehyde content can be directly occupied.

Methods to remove formaldehyde: 1. More ventilation, the concentration of harmful gases in the newly renovated house is high, the most economical way is to open the window for ventilation and keep the air flowing like Pitong, or you can use a high-power electric fan to blow so that formaldehyde volatilizes faster, and the ventilation time is best more than 2 months. 2. Adsorption hair, use plants or activated carbon to absorb indoor formaldehyde, put it in the corner of the house, plants can beautify the ring ruler bridge, and remember to replace it regularly if you use activated carbon.

3. Formaldehyde treatment, now many professional companies in this line can find companies with good reputation and poor service to specialize in formaldehyde treatment.

The hazards of formaldehyde: 1. When you get up in the morning, you will feel dizzy, nausea, and even chest tightness; 2. Some people in the family will often have colds, especially the elderly and children, and it is not easy to heal; 3. No one smokes at home, but there will still be throat discomfort or breathing difficulties; 4. Children are prone to leukemia, and long-term residence of pregnant women will lead to infertility or fetal malformations. 5. The survival rate of plants at home is low, or there is a phenomenon of leaf wilting and high slow yellowing; 6. If there are some fish or other pets at home, they will die inexplicably; 7. After the new move, the domestic cats, dogs and even tropical fish die inexplicably.

Usually the standard value of formaldehyde is within the range, within this range people can live in the hood, but if formaldehyde is in it, you can try to live, that is, if the formaldehyde is in the room with the window open, it is possible to live, but at this time, it is necessary to open the door and open the window to maintain indoor and outdoor air circulation and smoothness. If a person has symptoms that are not adapting, such as dizziness, headache, nausea, vomiting, confusion and other symptoms, they need to go to the hospital immediately for examination and oxygen**. If formaldehyde is there, try to place green plants indoors, such as pothos, etc., which can help absorb a certain amount of formaldehyde, and also place a certain amount of activated carbon, which also has an adsorption effect on formaldehyde.

No, we can't do it. In the latest 2010 version of the "Code for Indoor Environmental Pollution Control of Civil Construction Projects" GB 50325, it is stipulated that the content of formaldehyde shall not exceed that of civil construction projects, including residences, office buildings, hospitals and schools.

Formaldehyde is greater than the national standard, so it cannot be moved in.

Harm to pregnant women and fetuses:

1. Immunity, reproductive thoughts, metabolism and other functions will be affected, and it is very easy to have symptoms such as dizziness, weakness, nausea, retching, irritability, and insomnia.

2. Induce fetal chromosomal abnormalities, resulting in fetal malformations, brain damage, congenital heart disease and other defects.

3. Cause poisoning, anemia and miscarriage of pregnant women, resulting in fetal death.

How to avoid and remove formaldehyde? 1.Don't over-decorate your home;

2.Use green and environmentally friendly decoration materials;

3.frequent ventilation;

4.Please ask a professional formaldehyde treatment company to remove formaldehyde treatment;

5.Don't think that it will be okay to dry for 1-2 months after the decoration, formaldehyde can be continuously released within 2 years after the rapid combustion of the decoration.

If the formaldehyde content per cubic meter in the air after measurement is greater than that, it means that formaldehyde has exceeded the standard, in this case it is best not to stay, formaldehyde problem has always been a headache, how to effectively deal with formaldehyde, formaldehyde control within a safe range? Here's the answer.

1. 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.

3. Using activated carbon is also a good choice. The surface of activated carbon is rich in pores, which can adsorb indoor odors, and also has a certain effect on pollution control, but the activated carbon treatment capacity is limited, and it will produce saturation after about half a month of use, and it is impossible to continue to work.

5. Photocatalyst is an auxiliary method for the treatment of formaldehyde, mainly because it cannot decompose formaldehyde in the dark or under lightless conditions, cannot operate around the clock, and its range of action is small, and it cannot effectively remove formaldehyde in the room deeply. In addition, photocatalyst itself is a chemical and needs to be used with caution

6. We all know that the easiest way to remove formaldehyde is to ventilate, and the family with poor room ventilation can accelerate the air flow inside and outside the room through the fan, accelerate the discharge of formaldehyde-containing air, which can effectively reduce the concentration of indoor pollutants, but it can only treat the symptoms but not the root cause, and this method may not be practical in the season when you need to keep warm.

The new home is well decorated, and the national standard is, if it is exceeded, it will not be moved in first. If you want to remove formaldehyde quickly, you can choose a good photophyll material for more ventilation, which is better. Then take the remediation measures:

Step 1: Open the windows for ventilation. The best way is to open the window for ventilation for a long time, and discharge the pollutants in the indoor air to the outside through air convection. It can also be assisted by an electric fan to accelerate the convection of indoor and outdoor air.

Step 2: Use activated carbon for air purification. 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: Adopt the plant decontamination method. 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.

If you use a formaldehyde detector, you don't dare to guarantee, because generally the cheaper formaldehyde detectors are semiconductors, semiconductors are greatly affected by temperature and other gases, and if you use a formaldehyde detection box for detection, whether to close the doors and windows for 12 hours in advance, whether the indoor temperature is above 23 degrees Celsius, are all influencing factors, the detection condition is to close the doors and windows for 12 hours in advance, and the indoor temperature is above 23 degrees Celsius, if other operating specifications, it is a more serious exceedance, If the closed doors and windows are shorter than twelve hours, the formaldehyde in your house is already very serious.

Children, pregnant women and the elderly are the most direct victims of indoor pollution hazards, especially children, who are more vulnerable to indoor pollution than adults, and the damage caused is irreparable for a lifetime. Because children are different from adults, they are in the process of growth and development, with unstable hematopoietic function, poor hematopoietic reserve capacity, and hematopoietic organs are susceptible to infection, therefore, the impact of excessive indoor pollutants on children's hematopoietic organs will be more serious than that of adults, and it is more likely to cause serious diseases such as leukemia. On the other hand, children spend more than 90% of their time indoors, and even more so when they are exposed to pollution. Then there is the incomplete development of children's language expression ability, which is easy to ignore, and when the problem is found, it is irreversible. According to a survey by experts in the United States, 65% of children suffer from asthma to varying degrees, which is caused by renovation pollution.

The maximum allowable concentration of formaldehyde in indoor air in China is: milligrams cubic meters for first-class buildings and milligrams cubic meters for second-class buildings. Therefore, the formaldehyde content is greater than milligram cubic meter, and it cannot be occupied.

Formaldehyde and are mild pollution, but it will also pose a threat to human health, formaldehyde will make the human body cause obvious discomfort, induce rash, dizziness, asthma and other allergic reactions, long-term residence and even affect the reproduction of offspring, it is not recommended to stay, it is best to use activated carbon, photophyll and other materials to remove formaldehyde. My friend used this method before and it worked well. If economic conditions permit, it is also a good choice to invite a large-scale and well-reputed testing and governance organization to come to the door.

The indoor formaldehyde concentration standard is , the formaldehyde you said has exceeded the standard, which is not conducive to living, and it is recommended to ventilate for a period of time. When formaldehyde is reached, there is a peculiar smell and discomfort.

The most useful method of removing formaldehyde at the moment:

Step 1: Open the window for ventilation, the initial one to two weeks, summer and winter will take longer, in addition, in order to accelerate the indoor and outdoor air exchange, you can also use an electric fan.

Step 2: After the first step, the indoor pollution has become several times from dozens of times, or even hundreds of times of exceedance, and then the formaldehyde emission enters a slow process, no matter how ventilation, it is impossible to remove it at once.

First of all, flowers and plants, such as spider plants, cactus, green plants, etc., these plants have a certain odor-absorbing effect and can remove harmful substances in the air;

Secondly, deodorant, pay attention to see if it is toxic. Of course, ventilation and ventilation should continue at this stage.

Step 3: At the same time of ventilation and plant action, you can use clear mangreen nano photocatalyst to continue to spray the room to remove formaldehyde and other harmful substances in an all-round way, which can quickly decompose and adsorb formaldehyde as low as. It can be purified in about a week.

I have never heard of formaldehyde in beer, only know that when formaldehyde reaches a certain concentration indoors, people will feel uncomfortable, and more than the formaldehyde concentration can cause eye redness, itching, throat discomfort or pain, hoarseness, sneezing, chest tightness, wheezing, dermatitis, etc. Newly renovated rooms have high levels of formaldehyde, which is a major cause of many diseases. Long-term exposure to formaldehyde increases the risk of developing specific cancers such as Hodgkin lymphoma, multiple myeloma, and myeloid leukemia.

The following methods are recommended to prevent formaldehyde poisoning:

1) Improve indoor ventilation equipment and buy indoor air purifiers, but it is quite expensive.

2) It is also good to grow potted plants, aloe vera, cacti and other green plants, which is convenient and good.

3) Put some coconut vitamin carbon containing graphene indoors to remove formaldehyde, which has a long aging time, decomposes formaldehyde and other harmful substances well, and is not easy to cause secondary pollution.

4) The use of aromatic substances or the placement of fruits, vegetables, etc., can only cover the formaldehyde odor, can not be removed.

Summary. Formaldehyde is a harmful substance, and long-term exposure to high concentrations of formaldehyde may cause adverse effects on the human body. According to the Indoor Air Quality Standard (GB T 18883-2002), the standard indoor air quality limit for formaldehyde is milligrams cubic meters (mg m).

According to the information you provided, the formaldehyde concentration reached milligrams of cubic meters, which exceeded the indoor air quality standard limit. Therefore, this concentration of formaldehyde has reached an unsafe level, and it is recommended that you do not stay in this room, and you need to take steps to reduce the formaldehyde concentration. Formaldehyde concentrations can be reduced by ventilation and the use of formaldehyde scavengers until the indoor air quality meets safe standards.

The TOC was also exceeded.

Formaldehyde is a harmful substance, and long-term exposure to high concentrations of formaldehyde may have adverse effects on the human body. According to the "Indoor Air Quality Standard" (GB T 18883-2002), the standard indoor air quality limit of formaldehyde is milligram cubic meter (mg m). According to the information you provided, the formaldehyde concentration reached milligrams cubic yards meters, which exceeded the standard limit for indoor air quality.

Therefore, this concentration of formaldehyde has reached an unsafe level, and it is recommended that you do not stay in this room, and you need to take steps to reduce the formaldehyde concentration. Formaldehyde concentrations can be reduced by ventilation and the use of formaldehyde scavengers until the indoor air quality meets safe standards.

I found a formaldehyde removal in addition to the result of a bigger smell, I don't know what the reason is.

Methods for removing formaldehyde usually include ventilation, formaldehyde scavengers, and activated carbon adsorption in spring. If you have used a formaldehyde scavenger or other method of removing formaldehyde, but the odor in the room is more pronounced, there may be one of the following reasons: The formaldehyde scavenger is used in the wrong way

Some formaldehyde scavengers need to be used according to the instructions and dosage, if used incorrectly, the scavenger may not work well and even produce new odors. Insufficient ventilation: Ventilation is an effective way to remove harmful gases such as formaldehyde.

If formaldehyde scavengers or other methods are used without adequate ventilation, it is difficult to effectively remove harmful gases from indoor air. Other volatile organic compounds: Formaldehyde removal methods may not completely remove other volatile organic compounds, which can also cause odors.

For example, furniture, carpets, finishing materials, etc., can release volatile organic compounds. If this happens to you, it is recommended that you re-evaluate the levels of formaldehyde and other harmful gases and take appropriate measures to reduce the concentration of pollutants in your indoor air, such as adequate ventilation, use of air purifiers, etc. If the situation is more serious, you can consider seeking a professional air testing agency to test and provide corresponding solutions.
