What should I do if the formaldehyde in the newly renovated house exceeds the standard? It is best to ventilate for several months before moving in, and it is not good to wait for several months without ventilation. Pay attention to the following points after check-in:
1, ventilation is preferred, and convection is the best choice for newly renovated houses.
2. It is dangerous to turn on the air conditioner when it rains, and it is inconvenient to sleep. Open the doors and windows for ventilation. It is suggested that you can buy a special air purifier in in addition to formaldehyde if you have the conditions (most purifiers have poor in addition to formaldehyde effect, but the general filters with good effect are relatively large, with carbon content above 2 kg). Such as Bruyal 503 and forest princess C03. )
3. Keep enough sleep. Poor sleep, decreased resistance, and excessive formaldehyde are dangerous.
4, eat more fruits and vegetables, supplement vitamin C, can improve resistance.
If you have symptoms such as sore throat, bleeding teeth, and general fatigue, you should pay special attention. It is recommended not to stay for the time being.
In addition to formaldehyde (it should be said that apart from decoration pollution, formaldehyde is only a small part of pollutants in decoration pollution) focuses on prevention. If the formaldehyde exceeds the standard after decoration, there is no good way to remove it at present. Some companies in in addition to formaldehyde can reduce the concentration of formaldehyde by spraying chemicals, but these chemicals themselves are unsafe and may cause other pollution. This paint has been used for thousands of years, but it is still polluted. It has been difficult for in addition to formaldehyde to avoid pollution for decades. Decoration pollution formaldehyde is only a small part, which does not reduce formaldehyde, but increases other pollution, which is not worth the candle. The following points are recommended to reduce the danger to some extent.
Is it normal for formaldehyde in newly renovated houses and kitchens to exceed 0.8? Let's get some air. Ventilation should be provided after renovation. Every decoration project is within the standard, but it is likely to exceed the standard.
I don't know how you got this information. If it is the information obtained from the normal test, this is not beyond the standard.
This is the content of free formaldehyde in the air.
If you are not sure yourself, I suggest you go to a professional testing company for testing. The standard of formaldehyde content in indoor environment is 0. 1, but your detection value obviously exceeds the standard. Please pay attention to ventilation.
The improvement of living environment air quality mainly includes:
1. More windows for ventilation;
2. Put some activated carbon and nano-live ore indoors to absorb the odor and toxic and harmful substances in the air, but the activated carbon should be dried once every two weeks to maintain its adsorption capacity and activity, while the nano-live ore does not need to be dried;
3. You can raise some green broadleaf plants indoors, and you can also absorb toxic and harmful substances;
4. You can cultivate some ornamental fish, which will help to maintain good indoor humidity and make the environment feel more alive;
5. Be sure to clean and dry the floor, carpet, bedding, sofa and other places that are prone to dust, so as to reduce the impact of biological factors of mites on the living environment.
Good decoration will have formaldehyde residue. You'd better buy some grapefruit, as long as the skin is enough. You can also eat onions or cook pineapples in an electric stove.
Because grapefruit peel, onion and pineapple can absorb harmful gases.
Be careful that these things can't be put together, otherwise they taste strange, and onions and grapefruit skins don't need to be cooked.
I personally like to use pineapple. I hope it helps you.
Do you know what instrument can be used to measure formaldehyde in newly renovated houses? What symptoms will people experience when formaldehyde exceeds the standard! I have bought very few testing equipment myself. Now, after many new houses are bought, the developers will give you an air quality detector, but you still have to go to the air quality testing agency to invite people to conduct on-site testing. If only formaldehyde is detected, one point seems to be more than 100 yuan. Ordinary houses need to be tested at three points. Of course, you can decide the location of the test yourself, such as bedroom or storage room.
Detect newly renovated houses and newly bought furniture, or when the indoor air quality is not good; It is not advisable to move in immediately after renovation, and windows should be opened for ventilation, so that indoor polluted air can be distributed; If the formaldehyde in the indoor environment has exceeded the standard, it should be handled in time. At present, formaldehyde treatment products mainly include: air purifier, which has a certain adsorption effect on indoor formaldehyde and other pollutants; Deodorant and formaldehyde scavenger, used in decoration engineering, can effectively reduce free formaldehyde in wood-based panels; Harmful gas adsorbers and furniture adsorbents can catalyze the decomposition of indoor formaldehyde and other harmful gases; Formaldehyde sealing agent, coated on unpainted furniture interior wallboard and man-made board, can reduce formaldehyde release; Using plants for purification, chlorophytum, aloe and agave can reduce the indoor formaldehyde concentration.
Hazards of exposure to high concentration of formaldehyde: respiratory edema, eye * * *, headache. This will lead to asthma, even emphysema and lung cancer. In addition, direct contact with formaldehyde can cause allergic dermatitis, pigmentation and necrosis;
The prominent manifestations of formaldehyde poisoning are: headache, dizziness, fatigue, nausea, vomiting, chest tightness, eye pain, sore throat, loss of appetite, palpitation, insomnia, weight loss, memory loss, and autonomic nervous disorder.
In addition, long-term inhalation of formaldehyde is particularly harmful to some special people:
1. Children (especially infants): It can lead to mental retardation, brain injury, physical retardation, and blood diseases.
2. Pregnant women: it is easy to cause fetal malformation and even death.
3. The elderly: can cause cardiovascular and cerebrovascular diseases such as stroke and myocardial infarction.
In fact, most formaldehyde in home decoration now exceeds the standard. The best way, of course, is to open the window and ventilate, and then move into a new home in about a month. People should also pay attention to ventilation and buy some plants to absorb harmful substances such as formaldehyde and radon.
I hope it helps you, and pay attention to something that is not a big problem.
Whether the newly renovated house smells is formaldehyde exceeding the standard. First, the indoor new house decoration has an odor, not necessarily formaldehyde exceeding the standard, but generally there will be formaldehyde, which needs to be removed, otherwise it will be harmful to the human body.
Second, in addition to formaldehyde's method:
1 Put salt water into the new house
Using the water-soluble property of formaldehyde, you can put a few pots of water in each room, which can initially absorb a lot of pungent smell in the room.
2 Indoor ventilation
Formaldehyde is a volatile substance, which can be used to open the doors and windows of a room and keep indoor and outdoor air convection. This can effectively remove formaldehyde at home if you persist for about 2 months.
3 activated carbon, tea, etc.
Something with the function of absorbing odor can be used to improve indoor air quality. At present, the most commonly used is activated carbon. Placement of about 50g of activated carbon per square meter can play a good adsorption role on formaldehyde, but at the same time, attention should be paid to the replacement of activated carbon, which is generally appropriate once every 7 to 8 months. In addition, tea, grapefruit peel, onion slices and white vinegar can also adsorb formaldehyde.
Four kinds of green plants
Plant adsorption method is also a good choice. Many green plants, such as chlorophytum, cactus, Brahma, cycad, chrysanthemum and so on. , has a strong ability to absorb formaldehyde.
5 scientific preparation
Emerging scientific preparations and research products, such as formaldehyde scavengers and photocatalytic decomposers popular in the cash market, can effectively remove formaldehyde and other harmful substances in new houses.
Third, formaldehyde.
Chemical formula HCHO, also known as ant aldehyde. Colorless gas, with a special smell, has a * * * effect on human eyes and nose.
Fourth, people's network: sc. Man .. N2/2016/0713/c345511-28656923-3.
Formaldehyde in the newly renovated house exceeds the standard. Can you rent it out? It's best to rent it after treatment. The harm of formaldehyde is still quite great.
Effects of different concentrations of formaldehyde in indoor environment on human health Scientific research has proved that formaldehyde has a negative impact on human health. The hazards of different concentrations of formaldehyde in indoor environment are also different, and the hazards increase with the increase of formaldehyde concentration in the air. The olfactory threshold of formaldehyde (the concentration that most people can perceive with olfactory organs) is 0.06~ 1.2mg/m? The eye * * * threshold (the concentration that most people can feel through their eyes) is 0. 1 ~ 0.5 mg/m? .
When the formaldehyde concentration per cubic meter reaches 0.06-~0.07mg, children will have mild asthma.
When the concentration of formaldehyde in the air per cubic meter reaches 0. 1mg, it will have peculiar smell and make people uncomfortable.
When the concentration of formaldehyde in the air per cubic meter reaches 0.5 mg, it will cause tears in eyes.
When the concentration of formaldehyde in the air reaches 0.6 mg per cubic meter, it can cause throat discomfort or pain.
When the concentration of formaldehyde per cubic meter of air is high, it can cause nausea and vomiting, cough, chest tightness, asthma and even pulmonary edema.
The concentration of formaldehyde in the air per cubic meter reaches 30mg/m? When, will immediately lead to death.
Common in addition to formaldehyde methods in the market are:
1, photocatalytic catalyst removal method (safe and effective, no secondary pollution, recommended)
2. Formaldehyde blocking agent? It is easy to produce secondary pollution.
3. Formaldehyde eliminator
4. Physical adsorption method (in addition to formaldehyde air purifier)
5. Green plants
Main technology of eliminating formaldehyde pollution products in indoor environment
The first is physical adsorption technology. Mainly all kinds of air purifiers, some domestic manufacturers have produced specialized formaldehyde purifiers, but most manufacturers still mainly produce mechanical filter screens, ozone and air negative ion generators. The international manufacturers of purifiers include Fairbold, Honeywell, Toshiba, Hitachi, Sharp, Philips and so on. They still mainly produce products with physical efficiency. This kind of products mainly adsorb suspended solids in the air, and also have a certain adsorption effect on indoor pollutants such as formaldehyde.
The second is catalytic technology. Catalytic technology, also known as cold catalytic technology, is mainly based on multi-component and multi-phase catalysis combined with ultra-micro filtration, so as to ensure that various harmful malodorous gases are decomposed into harmless and odorless substances at normal temperature and pressure, and simple physical adsorption is changed into chemical adsorption, and adsorption and decomposition are carried out at the same time, thus improving the types, adsorption efficiency and saturation capacity of adsorbed polluted particles, avoiding secondary pollution, and the service life of adsorption materials is more than 20 times that of ordinary materials, which is relatively targeted and can catalyze harmful gases such as indoor formaldehyde. At present, harmful gas adsorbers and furniture adsorbents on the market belong to this kind of products.
The third is chemical neutralization technology. At present, experts have developed various deodorants and formaldehyde traps. This kind of products generally use complexation technology to neutralize the harmful gases in the air by destroying the molecular structure of formaldehyde, benzene and other harmful gases, and then gradually remove them, and finally achieve the purpose of improving indoor air quality. However, attention should be paid to the timing of use, and it is best to use it in combination with decoration projects, which can effectively reduce the free formaldehyde in wood-based panels.
The fourth is air negative ion technology. Rare mineral stones with obvious thermoelectric and piezoelectric effects are mainly selected as raw materials and added to wall materials. After decoration and painting, the air and the moisture in the air are ionized in the process of contact with the air to produce negative ions, which can be polarized and discharged outward, thus achieving the effect of purifying the indoor air.
The fifth is the material sealing technology. Aiming at the formaldehyde in various wood-based panels, experts have developed a sealing material called formaldehyde sealant, which can be used to seal the formaldehyde gas in furniture and artificial panels, and can be painted on the interior wall panels and wood-based panels of furniture without paint treatment, effectively slowing down the release of formaldehyde in various wood-based panels.
