How do I detect formaldehyde myself? How is formaldehyde detected?

There are many ways to detect formaldehyde yourself, such as:

1. By smell:In fact, formaldehyde itself has no taste, but when the formaldehyde concentration is very heavy, there will still be a smell, if you can feel the dazzling, pungent, and pungent feeling when you enter the room, then it is very likely that the formaldehyde exceeds the standard.

2. Formaldehyde self-test box:The formaldehyde self-test box can be seen according to the color of the self-test box, but the degree of formaldehyde exceeds the standard, but the accuracy.

Not very high, just for reference when using it.

3. If the indoor formaldehyde exceeds the standard, the indoor animals and plants will also have abnormalities, such as animals can not lift their spirits, and the green leaves of plants are wilted and wilted, which may be caused by excessive indoor formaldehyde.

If the indoor formaldehyde exceeds the standard seriously, it is necessary to carry out formal testing, hire some professional formaldehyde removal companies, use professional methods and equipment for testing, which is more reliable, and can formulate a supporting treatment plan for treatment after testing.

There are endless and diverse ways to remove formaldehyde, so why is removing formaldehyde still such a headache? There are two reasons, one is because formaldehyde is a toxic gas, a little careless, it will affect health, and the other is because there is too much false information in the network, and it is difficult to screen.

1. Ventilation. Open window ventilation is a very simple method to remove aldehyde, the purification principle is indoor and outdoor air circulation replacement, can release free formaldehyde and other harmful gases in the indoor air to the outdoors, reduce the indoor formaldehyde concentration. The efficiency of its aldehyde removal is directly related to the size of the outdoor wind, and the greater the outdoor wind, the higher the purification efficiency.

2. Fan. Ventilation is an indispensable method of removing formaldehyde indoors, but when the outdoor wind is not strong enough, it is necessary to strengthen ventilation. At this time, you can buy a high-power industrial fan to assist in the removal of harmful gases in the house, which can accelerate the circulation of air inside and outside the house, which is of great help to remove indoor decoration pollution.

3. Ruishi. Ruishi is a new generation of air purification products, mainly used to eliminate formaldehyde, benzene, radon, TOVC and other harmful gases released by interior decoration materials and various items, the adsorption capacity is dozens of times that of activated carbon, but also has the function of decomposition, and does not need to be dried, easy to use.

4. Activated carbon.

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.

5. Muguang blue.

It is a high-quality formaldehyde removal product superior to photocatalysts, although it requires high-intensity operation and professional technology, it is not limited by any specific reaction conditions, and there is no harmful volatiles produced in the process, and there is no secondary pollution. It can fundamentally solve the problem of indoor formaldehyde pollution, without damaging the internal and surface structure of the substrate, while maintaining the original beauty. Under the guidance of professionals, the best formaldehyde removal effect can be achieved.

6. Air purifier.

The air purifier has a good filtering effect on odors and indoor pollutants, and can achieve the purification effect relatively quickly, but it needs to be continuously turned on 24 hours a day, and the purification range of each machine is limited, and each room needs to be configured, so the cost of using it will be relatively high, and the cost of using the whole house is a bit high, and families with enough budget can give it a try.

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

The product does not require specific reaction conditions, does not produce any harmful volatiles during the reaction, and does not cause secondary pollution. Solve the problem of indoor formaldehyde pollution from the source, without causing damage to the internal and surface structure of the substrate, while maintaining the indoor aesthetics.

3. High temperature and drying can accelerate the volatilization of formaldehyde and other harmful substances, so you can take out drawers, movable furniture, mattresses, etc., and take them to the balcony for ventilation and drying.

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

5. Under certain conditions, the formaldehyde scavenger reacts with formaldehyde to generate other substances that are not harmful to health, so as to reduce the concentration of formaldehyde in the room. But it's also a chemical in its own right, and if used incorrectly, it can be another source of pollution indoors.

6. Use an air purifier to remove formaldehyde, which is a popular method in recent years, but now there are many brands on the market, and it is recommended to choose products marked with the function of "removing formaldehyde", you must be cautious when choosing, it is not recommended to choose below 1500, and the formaldehyde filter element also needs to be replaced regularly when used!

Method 1: Smell the smell, if you enter the room and smell a very pungent smell, and you will also experience dizziness and nausea, it means that the formaldehyde in the room is very high.

Method 2: According to the plant can be tested, put a few more pots of potted plants indoors, if the plant is dry and dead, it means that the formaldehyde content exceeds the standard.

Method 3: Use the formaldehyde self-test box to detect, put the test paper indoors for a period of time, and then look at the color on the self-test paper.

There is a pungent smell when you enter the house.

You can put a potted plant in the house and let it sit for a while to see if the plant wilts.

Just renovated house, formaldehyde will fill every corner of the room, how to effectively remove formaldehyde has become a problem that homeowners must overcome, the following is a brief introduction to some faster and more effective ways to remove formaldehyde.

1. Activated carbon.

There are a large number of irregular pores inside, among which the pores similar to formaldehyde molecules will adsorb formaldehyde, which can achieve the purpose of purifying the air, but the number of internal pores is limited, and it may cause secondary pollution when adsorbed is saturated, so it must be replaced regularly when used.

2. Arrowstone. It is a pure natural ore, with regular honeycomb voids inside, its specific area is huge, formaldehyde can be efficiently adsorbed, 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.

3. Muguang blue.

It is a high-quality formaldehyde removal product, which is superior to photocatalysts. After spraying, it can quickly penetrate into the inside of the formaldehyde pollution source, and the formaldehyde that takes 3-15 years to volatilize will be released at one time, and it will be decomposed into harmless carbon dioxide and water. The product does not require specific reaction conditions, can continue to decompose formaldehyde, benzene, TOVC and other harmful substances for 24 hours without interruption, and does not produce any harmful volatiles during the reaction process, will not cause secondary pollution, and can solve the problem of indoor formaldehyde pollution from the source.

4. Plants. Plants can remove formaldehyde, although formaldehyde can be removed, but the amount of formaldehyde it absorbs is very limited, and when the indoor concentration is high, if the plant alone relies on formaldehyde adsorption, the amount is very large.

5. Open windows for ventilation.

If you want to remove formaldehyde and odor as soon as possible, the first thing to do is to open the window for ventilation, open the cabinet doors and drawers at the same time, and dilute and discharge the formaldehyde to the outside through air convection. Although this step is simple, it is also necessary to pay attention to the weather conditions, so as not to break the newly renovated home environment with strong wind and rain.

If there are children or the elderly at home, it is recommended to use a natural way to open windows for ventilation + green plants + adsorption products to treat indoor formaldehyde problems, which is practical and healthy.

<> formaldehyde exceeded. 1. Seal the room for 1 hour, and open the furniture doors and drawers;

3. Use a formaldehyde detector for detection, and the results can be more accurate by subtracting the formaldehyde value in the upwind direction of the outdoors.

1. Professional testing institutionsFind a professional testing agency: There are many testing institutions and companies now, as for which one is more professional and formal, there are different opinions on the Internet, and this needs to be carefully chosen by friends.

2. Formaldehyde detection boxEasy and fast operation; Low lower limit of sensitive detection; It can be operated on site and other characteristics, so many people choose to use this, but although it is convenient, the detection effect is not ideal, and the error is very large.

You can use the formaldehyde test box or find a professional formaldehyde testing agency, and the formaldehyde content in the indoor air mg m3 can be moved in normally, if it exceeds this standard, even if it is only mildly polluted, it is not inhabitable. Don't take chances, there are many cases of harm caused by indoor air pollution, and you should never gamble with the life and health of yourself and your family. There are also many ways to remove formaldehyde in daily life, so let's learn about it together.

1. Opening windows for ventilation may be the easiest and fastest way to remove formaldehyde, but the most important premise of ventilation to remove formaldehyde is to maintain ventilation. For example, in summer and winter, when the air conditioner is turned on, the doors and windows are closed or there is no wind outside, the effect of removing formaldehyde cannot be achieved.

2. 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.

3. Activated carbon is a more effective method to purify the air, it has a strong adsorption effect on formaldehyde and other harmful substances, and the smaller the particles, the better the adsorption effect. It should be noted that most activated carbons have certain adsorption limits, and once saturated, they will no longer be absorbed, but will appear desorption, releasing absorbed harmful substances.

5. The fan can play the role of "inducing air" to accelerate the discharge of the gas containing free formaldehyde in the room to the outdoors, this method is only useful for the house with poor ventilation, and has little effect on the house with good ventilation effect.

6. In the case of high temperature, it can promote the conversion of formaldehyde in the bound state into free formaldehyde and reduce the total content of formaldehyde, because formaldehyde penetrates deep into the inside of the plate, although the formaldehyde cannot be completely removed, but the effect is still very obvious

You can use a formaldehyde self-test box for rapid self-testing of indoor formaldehyde concentration. Perform tests.

A small way to remove formaldehyde quickly.

1. Plants remove formaldehyde (slight effect), green plants can absorb carbon dioxide in the air under the action of sunlight, produce oxygen, and make the air very fresh.

2. Grapefruit peel and pineapple peel remove formaldehyde (no effect), grapefruit peel and pineapple peel have a unique fruity aroma, but it is also a folklore, not only can they not remove formaldehyde, but the indoor formaldehyde content will also begin to increase.

3. Air freshener in addition to formaldehyde (***), air freshener actually only covers up the odor, it is unable to remove formaldehyde from the root, some inferior air fresheners contain aromatic substances will even increase the pollutants in the room.

4. Ventilation method (auxiliary effect), the "incubation period" of formaldehyde can be as long as 3-15 years, if only the ventilation method is used, at least the window must be opened every day for more than a year to remove formaldehyde, it can only play an auxiliary effect.

5. Activated carbon adsorption method (general effect), the skin ability of activated carbon itself is limited, and many consumers cannot feel the effect when using it, and this process is relatively long.

6. Formaldehyde scavenger (effective but need to be carefully screened), formaldehyde scavenger is also divided into many kinds according to its nature, it is recommended to purchase it under the guidance of professionals, and the top ten brands will be more trusted.

7. Photocatalyst (effective but very limited), the photocatalyst should be colorless and transparent, the photocatalyst is a catalyst, which does not react itself, and can promote chemical reactions under certain conditions, and it can only play a role under ultraviolet conditions.
