How to tell if you have formaldehyde at home How to tell if you have formaldehyde at home

1. If you encounter this phenomenon when you move into a new home, you must be vigilant, if you happen to move into a new home, and your children and your family happen to encounter the following situations, it is likely to be the result of excessive formaldehyde, indicating that formaldehyde has not been cleaned up.

2. According to the observation of human reactions, when there is formaldehyde, people feel poor breathing indoors, foreign body sensation in the throat, family members may often catch colds or share the same disease, children will often cough, immunity will decrease, and there may be congestion on the surface inexplicably.

3. The most intuitive way to judge whether formaldehyde exceeds the standard is to smell the smell. If you are uncomfortable after sleeping, nausea and want to vomit, the room does not come every other day, and if there is an uncomfortable smell again, the formaldehyde content is relatively high. Only when you can't smell anything, the amount of formaldehyde at home will not be particularly high.

4. If you are sure that there is formaldehyde, if you want to know the formaldehyde content, you can buy a formaldehyde tester online. The tester can probably detect whether the formaldehyde exceeds the standard. After measurement, corresponding protective treatment is made according to the excess amount of formaldehyde.

5. Most of the plants in the house can be detected according to the state of the plant to detect whether it contains formaldehyde, if the plant is not in good growth state and is easy to turn yellow, it may be that the indoor formaldehyde exceeds the standard.

6. Go buy some formaldehyde test strips. Check the use of formaldehyde test strips and judgment criteria on the Internet, the reaction part of the front end of the test strip is yellow, and the reaction part of the test strip is yellow. It means that the concentration of formaldehyde in the room is higher; When the reaction part of the test strip is light yellow, it represents the concentration of indoor formaldehyde is low, and it is necessary to refer to the standard color card to read out the general value to determine whether the indoor formaldehyde concentration exceeds the standard or the general range of the standard, and whether the formaldehyde exceeds the standard can be judged by the reaction color.

7. Using the colorimetric method, formaldehyde in the air is absorbed by the absorption solution, and reacts with 4-amino group in the alkaline solution, which is oxidized by potassium periodic acid to form a purple-red compound, and the color of the formaldehyde content is proportional to the formaldehyde content, and the formaldehyde content is quantitatively determined by colorimetry.

There is no need to worry about excessive formaldehyde in the new house.

There are generally four ways to determine whether there is formaldehyde in your home:

1. Self-perception, often feeling suffocated, nauseous, even dizzy, and uncomfortable throat.

2. Be good at observing animal and plant reactions, such as plants withering and dying, pets getting sick, not eating food, low resistance, and decreased vitality.

3. Professional formaldehyde testing, find a professional formaldehyde company for testing.

4. Formaldehyde self-test box, with the help of formaldehyde self-test box detection, in order to facilitate the comparison of receipts before and after treatment, you can take pictures of the initial test results to record the formaldehyde concentration, so as to facilitate comparison with the test results after treatment.

In addition to formaldehyde, use the following tricks, and within half a year, formaldehyde will be eliminated.

The first way to remove aldehydes: insist on ventilation

Whether it is before or after moving in, as long as the weather permits, try to keep ventilation all day long, ventilation is not only effective, but also does not cost money. But if the weather is bad, it doesn't matter, we can open a window crack and then cooperate with a fan to blow the air, which can also have the effect of air circulation replacement.

The second trick of aldehyde removal: scientific and effective purification

Compared with the carbon bag, it not only adsorbs and purifies more than ten times faster, but also adds a double group of decomposition components, which can play a role in decomposing formaldehyde.

The third trick of aldehyde removal: decomposition medium purification

Compared with ordinary sprays, it is not only safe and non-toxic, does not hurt furniture, but also can penetrate the inside of furniture panels, induce decomposition of formaldehyde from the source, and the speed and efficiency of purification are higher.

The fourth trick of aldehyde removal: wipe the furniture with salt water

The board and furniture used in decoration are the main odor of the home, formaldehyde and other harmful gases will adhere to the surface of the board, wipe the surface with mild salt water, can take away some harmful substances; Formaldehyde is soluble in salt water, and wiping the surface frequently also has a certain effect on removing odors.

The available tools for measuring formaldehyde on the market are a formaldehyde self-test box, a handheld formaldehyde detector, and a professional testing institution to do formaldehyde testing. Each of the three has its own advantages and disadvantages

Check it out and you'll find out. Formaldehyde test kits are the best choice for testing formaldehyde at home, and this method is simple and economical. If the indoor formaldehyde detection exceeds the standard, the following methods are also more suitable for home aldehyde removal.

1. Wise Stone.

It can actively adsorb indoor free formaldehyde, the process will not be affected by any external factors such as temperature, humidity, light, etc., the adsorption rate of formaldehyde is also dozens of times that of ordinary adsorption materials, in addition to the unique decomposition function, the adsorbed formaldehyde can be decomposed into harmless carbon dioxide and water, and then discharged, so that its internal pores have been in an unsaturated state, and the aldehyde removal rate can reach more than 90%. 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.

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.

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

Fourth, the fresh air system.

The fresh air system can introduce fresh air outside and discharge harmful substances from the indoor space through the system's filtration device during the period when the windows cannot be opened, which will reduce the concentration of free organic pollutants in the indoor space to a certain extent and speed up the release of pollutants. Through continuous circulation, the indoor decoration pollution is controlled.

5. Photocatalysts.

The main principle of photocatalyst is that the spray will adhere to the surface of the object to form a strong film, on the one hand, it will slow down the release of formaldehyde, on the other hand, it will contact with the film during the release process, and oxidize formaldehyde by using the photocatalytic performance of the photocatalyst. However, in daily life, the film may oxidize and wear, and the effect will be halved.

The three stinkers have competed against Zhuge Liang, and the formaldehyde is the same, and it is recommended to combine several methods to stabilize formaldehyde in a safe range faster.

One: According to the physical reaction of the child and the family, if the family often feels nauseous, chest tightness, dizziness, or often colds, the resistance is getting worse and worse, the child's immunity is poor, and so on is likely to be the cause of formaldehyde. I don't smoke at home, but my throat is always uncomfortable, my breathing is not smooth, more and more families have **allergies, poor breathing, sore throat is equivalent to a symptom, pregnant women have been infertile for many years, or pregnant women are pregnant normally, and finally fetal malformations appear.

In conclusion, after moving into a new home, the feeling of physical discomfort is likely to be formaldehyde. Otherwise, if you are in good health and have moved into the house, you have **sick, **red and swollen, the situation continues to deteriorate, there is no sign of improvement, etc., you often feel that there is a pungent smell in your new home, and it will not be dispersed after a long time, and there are symptoms of formaldehyde poisoning. Two:

According to the survival response of animals and plants to determine, for example, withered and dead plants, planting greenery is not easy to survive. Families with pets tend to lose their appetite, no longer bounce around, and feel sluggish. The third method is to measure formaldehyde by detecting the box and comparing the color card tool.

But it can only be used as a simple reference, and in fact, there is a huge difference. So, we did find that some professional institutions are more assured of testing. As we all know, formaldehyde is a frequent visitor to new houses, and in newly renovated rooms, formaldehyde is inevitably contained in the adhesive, and the performance is better.

Therefore, people often choose to leave the new house for a month or two or even half a year after renovation, just to reduce the formaldehyde content and protect the health of their families. However, even if all formaldehyde removal methods such as adsorption method, plant absorption method, and activated carbon formaldehyde removal method are exhausted, the professional team cannot completely remove formaldehyde.

A testing organization with CMA certification qualification will conduct testing; One is to conduct testing by a testing agency without certification qualifications; Another is to buy relevant test instruments for testing.

There is a pungent smell at home, that is, there is formaldehyde, and I am really helping you look forward to adoption

The most intuitive way, buy some potassium permanganate balls, put them indoors for a few days, and see if the color is fading.

You can buy formaldehyde self-test box for a simple test, relying solely on the human body's sense of smell is not accurate, it varies from person to person, half of some people exceed the standard three times are not felt, the harm of formaldehyde is understood by everyone, when it is found that formaldehyde exceeds the standard, it must be dealt with in a timely manner, and several easy-to-use methods are recommended for everyone.

The easiest way to detect formaldehyde at home is to use formaldehyde test boxes, but the detection may be affected by temperature, humidity and space size. After introducing how to measure indoor formaldehyde concentration, let's bring you some efficient methods for removing aldehyde.

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. 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.

Methods for testing formaldehyde exceedances:

Method 1: Use the formaldehyde test box to determine whether the formaldehyde exceeds the standard

Formaldehyde test box is now a common choice of testing methods, this method is simple and easy to operate, although the test results are uncertain, but more or less still a little effect, I personally think that Ha, the first work before testing in this way is to close the test room for half an hour, and then test, in reference to the color scale table to judge whether the indoor air exceeds the standard, if the color is very light, it means that the indoor air quality is basically in line with the national standard, But once you find that the color depth has been deepening, then you should pay attention, this is likely to be a serious exceedance! It needs to be dealt with in a timely manner!

Method 2: Generally, if the formaldehyde concentration exceeds the national standard, you can judge whether the formaldehyde exceeds the standard from the smell at home

Especially in summer, due to high temperatures, formaldehyde will be quickly released into the air, if you can smell some pungent smell as soon as you enter the house or anywhere in the house, it is a reminder that formaldehyde exceeds the standard and needs to be cleaned up in time; In addition to the smell, the body will also tell you that the formaldehyde at home has exceeded the standard, but when the body has the following conditions, it is necessary to pay considerable attention to the formaldehyde problem, and it must be dealt with in time, otherwise the physical symptoms will be worse day by day:

1. When you get up, you obviously feel dizzy, nausea, and weakness in your limbs.

2. Due to long-term inhalation of harmful substances, the throat will often be uncomfortable, and it will be difficult to breathe when dryness and foreign body sensation are severe.

3. Just like the epidemic, everyone in the family has symptoms of coughing.

4. Weakened immunity, easy to get sick and catch a cold and cannot be relieved for a long time.

5. Plants at home are not easy to survive, and pets at home are also slow to respond.

Therefore, if the indoor formaldehyde concentration exceeds the national standard, we can easily find it in time, once it is found that the appeal of those situations should be done in time to detect the formaldehyde exceedance, and if the test results show that the state of excess is exceeded, it is necessary to do a good job in the treatment of removing formaldehyde in time.

No need to judge, there are all. The difference is that there are more and some are less.

Summary. Hello dear. There are several ways to determine whether there is formaldehyde in your home:

1. Formaldehyde detectorFormaldehyde detector is an electronic instrument for detecting formaldehyde, which detects formaldehyde concentration through electro-optical sensing principle, displays the real-time value of indoor formaldehyde through the electronic instrument, and conducts indoor real-time monitoring. 2. This method relies on your own body reaction to detect formaldehyde concentration, if the smell of the new bed is very pungent, we can stay at home for a while, through our own reactions, such as tearing, headache and other adverse reactions, indicating that there is formaldehyde. 3. Determine the indoor formaldehyde concentration through the reaction of animals and plantsThis detection method is to detect the formaldehyde concentration through the reaction of indoor animals and plants, such as whether the indoor breeding plants have wilted, or the animals have malaise in the new house, and whether there is formaldehyde can be judged from this situation.

The state stipulates that the standards for formaldehyde are as follows. The national standard of the People's Republic of China of the People's Republic of China, the health standard of formaldehyde in the indoor air stipulates that the maximum allowable concentration of formaldehyde in the indoor air is per cubic meter.

The national standard of the People's Republic of China for parquet stipulates: Class A parquet formaldehyde emission 9mg 100g; The release of formaldehyde from class B parquet is equal to 9mg 100g-40mg 100g. Technical requirements for national environmental labeling products:

Artificial wood flooring stipulates that the amount of formaldehyde released in the man-made board should be, and the amount of formaldehyde released in the wood board should be. For formaldehyde exceeding the standard, the aeration method and the adsorption method of activated carbon should also be considered for treatment. First of all, you should choose a professional formaldehyde detection agency to detect formaldehyde, if it does rise, you should actively use the above two methods to remove formaldehyde, so as not to cause harm to family members, and serious can also cause Bai Kaiqi blood disease.
