Although many news reports have repeatedly reported the "formaldehyde poisoning" incident, calling for reminding everyone to do a good job in formaldehyde control measures, there will still be many families who do not pay enough attention to formaldehyde poisoning, causing some tragedies.
After Mr. Lin's new house was ventilated and dried for more than half a year, the couple moved into the new house with their 4-year-old daughter. Only 1 month after moving into the new house, Mr. Lin's daughterSymptoms such as persistent high fever and cough suddenly appearedWarpHospital diagnosis of acute leukemia4 years oldofDaughterCauseInvalid death.
After his daughter was diagnosed with acute leukemia, Mr. Lin commissioned the municipal environmental monitoring station to monitor the air in the master bedroom of the new houseAccording to the monitoring report, the formaldehyde content is 039mg, exceededprovisionsThe standard is 4 times more seriously exceeded.
Among all those contacted, children, pregnant women and the elderly are particularly sensitive to formaldehyde, which is more harmful.
Children are different from adults, in the process of growth and development, hematopoietic function is unstable, hematopoietic reserve capacity is poor, hematopoietic organs are susceptible to infection, therefore, indoor pollutants excessive poisoning on children's hematopoietic organs will have a more serious impact than adults, more likely to cause leukemia and other serious diseases, the damage caused is irreparable for a lifetime.
In addition, children have nearThe above time is lived indoors and is polluted for a longer time. The American expert survey report saidSixty-five percent of children suffer from asthma to varying degrees, which is caused by renovation pollution.
The survey found that as many as 70% of the families who have moved into the home for 3-15 years still exceed the formaldehyde standard!Most people are moving into the house is formaldehyde detection everything is normal, why is there a phenomenon of repeated formaldehyde?
Mainly because of these two reasons:
1. Superimposed pollution at home
Superimposed pollution can be simply understood as an additive problem. The measurement standard of formaldehyde is based on the whole room, and the use of environmentally friendly furniture does not represent the overall formaldehyde content of the room.
10 pieces of furniture that meet the formaldehyde standard may create a space with excessive formaldehyde. Any decoration materials and furniture will contain a certain source of pollution to a greater or lesser extent, and will be released slowly over time.
2. Formaldehyde itself lasts for a long time
The harm caused by decoration pollution should not be underestimated, and many people know that formaldehyde volatilization time can be reached for the longest time5 years, but most people don't know why there is such a long release cycle, and some even have doubts.
This figure is summarized after rigorous verification.
The domestic literature on the development of formaldehyde mentions that:A professional study by Yokohama National University in Japan has shown that the release period of formaldehyde is generally 3-15 years. This also proves the sentence that "formaldehyde volatilization time can be up to 15 years".
And Qinghua professor Zhang Yinping also revealed: ".Both research and life experience have shown that after more than ten years, formaldehyde still cannot be volatilized is very common. Therefore, it is unrealistic to expect that formaldehyde will be emitted clean after a few months of opening windows for ventilation. ”
In addition, the frequent real cases in recent years have verified that this statement is not easy to come by.
In China, strictly speaking, formaldehyde standards are divided into two types of standards:
Class I civil buildings and Class II civil buildings, Class I civil buildings include residences, hospitals, elderly buildings, kindergartens, cars, school classrooms, etc.;
Class II civil buildings include office buildings, shops, hotels, cultural and entertainment venues, bookstores, libraries, gymnasiums, public transportation waiting rooms, restaurants, barber shops, etc.
The standard scope of formaldehyde for Class I civil buildings shall≤0.08mg/m3；Total volatile organic compounds (VOCs) 050mg/m3。
The scope of formaldehyde standards for Class II civil buildings shall≤0.10mg/ m3；The standard range of benzene is 00 9mg/m 3；Ammonia 020 mg/m3；Total volatile organic compounds (VOCs) 060mg/m3。
After the new house is renovated, many people can't wait to move in, but they dare not move in due to decoration pollution, so what is the indoor formaldehyde concentration related to?
1. Temperature
One of the main factors affecting the rate of formaldehyde evaporation is temperature.
A large number of studies have shown that formaldehyde molecules will be active at high temperatures, that is, the higher the temperature, the faster the volatilization rate of formaldehyde!
According to a study by the Seiko Norsenberg laboratory in Germany, the volatilization rate of formaldehyde increases by 04 times!
Second, the number of formaldehyde release sources
We believe that we can understand this very well, this is a typical quantitative change causing qualitative change.
3. Humidity
The higher the humidity, the higher the water vapor content in the air, and formaldehyde has the property of being easily soluble in water, so the increase in humidity will accelerate the release rate of formaldehyde in formaldehyde release sources such as plates.
Fourth, time
Because the volatilized formaldehyde will continue to accumulate in the indoor air, so as to exceed the standard!
The volatilization cycle of formaldehyde is as long as 3-15 years, that is, formaldehyde has enough time to accumulate and exceed the standard!
In addition, the long volatilization period of formaldehyde also shows that the ventilation and drying carried out after our decoration is only a temporary effort, and cannot permanently solve the problem of excessive formaldehyde.
Rumor has it that winter is the season of the year when indoor formaldehyde pollution is the worst.
1.In winter, the indoor temperature is generally high, which accelerates the release of formaldehyde.
It's the northern winter heating season. After heating, the indoor temperature generally reaches more than 20. At this time, formaldehyde hidden in paints, floors and furniture is released in large quantities.
2.Insulation, closed doors and windows, poor indoor ventilation conditions.
After entering the winter, most people are reluctant to open the windows often for ventilation, the indoor is closed, and the ventilation is poor, resulting in indoor air convection, a large amount of formaldehyde accumulates indoors, and people react slowly to harmful gases in winter, therefore, the formaldehyde violation is more serious.
3.Air convection, steam accumulation, and high indoor relative humidity.
The effect of humidity on formaldehyde is mainly due to the urea-formaldehyde glue in the plate is produced by the polymerization reaction of urea and formaldehyde. When the humidity increases, when the plate is damp, the urea-formaldehyde glue will decompose into urea and formaldehyde in water, thereby increasing the content of free formaldehyde in the plate and increasing the content of volatile air.
The decoration of indoor materials is also an important factor that leads to excessive formaldehyde.
In general, winter is a busy season for moving to a new house. Many owners rush to the New Year or next Spring Festival to move into new houses, and decoration pollution cannot be effectively distributed. Although many people will use green building materials when decorating, there are still hidden dangers.
Many people think that formaldehyde is far away from us, but in fact, as an expert environmental expert pointed out: a few inconspicuous things in the house are formaldehyde households, and you must be careful when buying and using.
1. Coating:A large amount of paint will be used when painting the wall, in order to make the wall and the paint more firm, a large number of glue will be used to reinforce, this material is the adhesive, so the formaldehyde index will seriously exceed the standard.
Composite Panels:In particular, wood flooring is one of the places where formaldehyde is hidden the most, its formaldehyde comes from the glue used in composite flooring, and the most used indoor is artificial flooring, with a formaldehyde value of up to 60%.
3. Wallpaper:Considering the aesthetics of the wall during decoration, wallpaper is generally used for decoration, in which the glue will contain a large amount of formaldehyde, which is extremely easy to volatilize a large amount of formaldehyde at room temperature.
4. Curtains and cabinets:Many people actually ignore the formaldehyde in curtains, because the main material is fabric. But in fact, in order to make the curtains more beautiful, not easy to wrinkle, not easy to fade, the manufacturer will add chemical additives to produce formaldehyde, so buy the curtains remember to clean them several times in the sun, formaldehyde is easily soluble in dry water.
If you also have these 4 items in your house, it is recommended to throw them away, because they are all "formaldehyde sources"!Formaldehyde is released for up to 15 years, and if our family members are poisoned by formaldehyde, it's no joke!
I've heard about formaldehydeThe volatilization cycle is up to 3 to 15 yearsMany people who move to a new home feel panicked. But in fact, the volatilization rate of formaldehyde in the home is gradually decreasing, and it is not a large amount of formaldehyde that has been released for 15 years.
The combination of data on the change of formaldehyde concentration in the house with time is plotted, and it can be seen that the formaldehyde concentration reaches a peak in about 5 months after decoration, and then gradually decreases, and reaches a relatively low concentration that is relatively safe for the human body after 6 months, and is released stably.
The degree of formaldehyde release in decoration materials will be affected by various factors such as wood type, water content, outdoor temperature and placement time.
Under normal circumstances, after 2 to 3 years, the formaldehyde content of the newly renovated interior can be reduced to the same level as the old house. A small number of furniture with inferior materials and high formaldehyde content may last up to 15 years. Therefore, it is recommended that after the decoration of the new house, it is best to take measures to reduce the formaldehyde concentration to ensure that the normal occupancy, otherwise the harm is very serious!
1. Respiratory diseases. Inhaling too much formaldehyde for a long time will lead to poor breathing, laryngeal edema, nasopharyngeal tumors and other serious diseases, so if you have symptoms of physical discomfort, you should go to the hospital for examination in time, stay away from the formaldehyde environment, and avoid serious effects on people's health.
2. Nausea, vomiting and dizziness. The most obvious feature of formaldehyde poisoning is severe nausea and vomiting, which can also lead to varying degrees of dizziness and fatigue, so it should be paid attention to avoid the symptoms becoming more and more serious.
3. Memory loss. Formaldehyde will cause serious harm to people's health, often living in an environment with high formaldehyde concentration will cause obvious memory loss, and will also cause patients to often have insomnia, dreams and physical weakness symptoms.
4. Induce diseases of the reproductive system. Severe formaldehyde poisoning will cause sperm malformations in men, and will also have a great impact on the health of the reproductive system of patients.
However, formaldehyde can't be seen or touched, and you can't wait until your children are poisoned by formaldehyde to find that formaldehyde exceeds the standard, right?
In fact, there are already signs of excessive formaldehyde!
1. Rub your eyes often and your eyes are red
Formaldehyde is a volatile gas, accompanied by strong irritation, which can cause conjunctival hyperemia, and in severe cases, it will also lead to vision loss, unable to see clearly, and the child's conjunctiva is very fragile and vulnerable to formaldehyde damage.
2. Cough for no reason, sore throat
Formaldehyde poisoning can initially resemble a cold or sore throat, so a lot of people will be confused. Formaldehyde is an irritating gas, if you breathe a lot of air with excessive formaldehyde, it will cause damage to the mucous membrane of our upper respiratory tract, resulting in frequent coughing, sneezing, sore throat, dry itching and other symptoms.
3. The child has an allergic reaction, itching, rash and so on
* Exposure to the air with excessive formaldehyde will also be stimulated, especially for some people with allergies and poor physique, which are more likely to cause allergies, causing symptoms such as itching and rashes, and even inducing urticaria in severe cases.
There is a very peculiar "magic method of removing aldehyde" circulating on the Internet, that is: if you want to remove formaldehyde for new furniture, then use the characteristics of formaldehyde soluble in water, you only need to wipe the furniture with water, back and forth several times a day, after a period of time, the formaldehyde of the furniture can be dissolved by water.
From a professional's point of view, this is simply a strange theory, although formaldehyde can indeed be dissolved in water, but the formaldehyde of furniture will not be dissolved because you wipe it with water a few times.
What is the reason for this?
1. The evaporation rate of water is relatively fast
Under normal circumstances, water will evaporate quickly, especially in summer and autumn, the evaporation rate of water is faster, at this time, often not much formaldehyde is dissolved, and the water has evaporated in the air.
2. This water can only dissolve a very small part of formaldehyde
After reading the above, someone may tremble and say, "Then I keep the surface of the furniture moist all the time, then it should always be okay, right?".Even if water is applied to the exterior of furniture and kept moist for a long time, it can only touch a small part of the formaldehyde dissolved in the air, and more formaldehyde is still permeated in the indoor air.
Unless, soak the whole house in water.
3. Formaldehyde is exuded from the inside of the furniture material, not from the outside
No matter how much we wipe and keep the furniture moist, we are only working on the outside of the furniture, in fact, we can't touch the real area of formaldehyde - the inside of the furniture material (unless the furniture is destroyed and soaked in water, but is this possible?).）
So, to summarize the above reasons, wiping furniture with water, no matter how diligent you wipe, there is nothing you can do to remove aldehydes.
Removing formaldehyde is a scienceThere are a lot of doorways, but there are too many misunderstandings, and the following local methods are trueCan it remove aldehydes?
1. Grapefruit peel tea stem removes formaldehyde
This type of approach is potentially more harmful. The grapefruit peel tea stalk will volatilize its own aroma and play a certain role in covering the smell, but it does not have a decomposition effect.
When we only smell the fragrance, we think that the harmful gases have been removed, but we don't know that the harmful gases are eroding our body, and these things contain a lot of water, which can play a role in humidifying after volatilization, which can play a role in dissolving harmful substances such as formaldehyde, and once it is dry, formaldehyde will volatilize again.
2. Fumigation vinegar removes formaldehyde
Some netizens said that fumigation vinegar can remove odors in home decoration. Vinegar is an acidic substance, which does have a weak effect on neutralizing ammonia in the air, and can also kill certain bacteria in the air by heating. However, it will not react with other harmful components such as formaldehyde.
3. Formaldehyde removal in plants is just a legend
In fact, plants can only absorb formaldehyde, and the effect is very slow and small. It has been proven that placing a pot of green algae in a room on the 100th floor can only absorb 05% formaldehyde, that is, 995% formaldehyde remains in the room. Therefore, it is not advisable to expect the plant to completely remove formaldehyde.
We can imagine the indoor environment as a source of pollution that is constantly emitting smoke, at this time we open the doors and windows, if the air intake is small or no wind enters the room, the air intake must be greater than the volatilization rate of the harmful substance.
Because the boiling point of formaldehyde is relatively low, after the temperature increases to 19 degrees, the amount of formaldehyde released will increase exponentially with the temperature, which is why indoor formaldehyde is easy to exceed the standardThe main reason
However, ventilation can only remove part of it, not "all"!
There are two main reasons:
1. The ventilation effect of window opening is very limited
When you think of removing formaldehyde, you will think of opening the window for ventilation, but you find that after opening the window for ventilation for more than half a year, after testing again, the formaldehyde at home still exceeds the standard, why is this?
After opening the window, the air circulation is able to remove formaldehyde in the room. But only when the wind is strong, the formaldehyde can be effectively removed after the window is opened. But many times, even if we open all the windows in our home, there is no wind or little wind outside. Therefore, the effect of opening windows to ventilate to remove formaldehyde is weakened.
2. Once the window is closed, it can easily lead to formaldehyde accumulation
The key point of opening windows for ventilation is to open windows, but when the weather is bad, the windows are on. Formaldehyde is released for up to 3-15 years and is still volatile. This leads to the accumulation of indoor formaldehyde after the windows are closed, which is likely to lead to contamination**, making the method of removing formaldehyde from windows ineffective.
Therefore, we should not only use the method of opening windows for ventilation, the effect is relatively poor, but also need to assist other methods to remove formaldehyde.
If we want to remove formaldehyde safely and efficiently, how should we remove formaldehyde really, quickly and effectively?
In fact, it is not very difficult to remove formaldehyde, and the choice of the right product is already half the success.
It is recommended that you choose such a fast and visual formaldehyde jelly, and I will introduce to you its awesomeness!
This formaldehyde jelly, it canActively grabs the formaldehyde free in the air and converts formaldehyde into water and carbon dioxide, which is simple and efficient to remove aldehyde.
The key point is active decomposition, not adsorption.
Like the bamboo charcoal, orange peel, and tea that we use in the tradition, we basically wait for the prey to come to the door, that is, which formaldehyde factor is floating in the air, and it will be caught if it is more unlucky, so the efficiency and effect will be much lower.
Many families still use the dirt method!
What's more, bamboo charcoal, which has no decomposition ability after adsorption, will release formaldehyde after absorbing formaldehyde!In fact, only by turning formaldehyde into harmless carbon dioxide and water and irreversible can the effect of real formaldehyde removal be achieved.
Don't look at it as just a tiny canIt only took 3 minutes to "see" the process of removing formaldehyde:
The initial formaldehyde concentration in a confined space is 014mg per cubic meter, while the sanitary standard for formaldehyde in the indoor air is specified as 008mg per cubic meter.
This value has exceeded the standard, but it is a common value in many families, which is what we call formaldehyde has been continuously released. Then, we put the formaldehyde jelly in it, and after 3 minutes, we magically found that the formaldehyde concentration dropped to 0014mg per cubic meter, not only within a safe range, but also removes 90% of formaldehyde.
First of all, from a security point of view:Because most of them are used at home, safety must be in place.
As a constituent party, the first step is to look at its foundation, that is, the cost list.
This formaldehyde jelly is a plant-based formula that can be directly contacted, non-toxic and non-irritating, even if the child accidentally touches it.
After all, it is to solve the formaldehyde poison gas, and the safety of the product itself is the foundation, otherwise it will be too painful to slap the face.
Secondly, in terms of efficiency:
Unlike other similar products that cannot get a real report on the effect of removing aldehyde, this formaldehyde jelly has the test reports of many institutions such as Tsinghua University Building Environment Monitoring Center, Micro Measurement, and Nano Laboratory, which proves its "ability" again and again.
According to the report of the Building Environment Testing Center of Tsinghua University, within 24 hours, the formaldehyde removal rate of formaldehyde jelly is 957%。
That's at least a full 1% higher than similar products!
Don't underestimate only 1%, in your own home, 1 more point of security, is 10 more points of security. If you take the college entrance examination, you can kill thousands of people by raising one point!
Each bottle of formaldehyde jelly comes with oneActivatorsDrip it into the jar before use and the product will be activated.
jelly releasedPlant-derived aldehyde removal ingredients, will be with the indoor air flow, contact with formaldehyde and other harmful moleculesFirmly adsorb and decompose them.
After activation2-3 hours, you can clearly see the formaldehyde net magic boxBegin to change colorFinish.
Formaldehyde net magic box of aldehyde removal components, passedIt reacts with formaldehyde uninterruptedly, decomposing while looking for it, leaving no chance for formaldehyde to "resurge".Secondary pollution will not exist!
After 12 hours, almost two-thirds of the color had turned yellow.
Within 48 hours, it turns milky white and begins to enter the "stable work period".
A week later, you'll seeThe dark blue color gradually turns pale yellow until it turns white "freeze-dried".The volume inside has also been reduced.
When it's completely shriveled up to the size of a coin, it's a reminder that you need to replace it in time.
Some friends may ask, how much range can such a small box manage?
The results of the test report show that in the area with less pollution, one can cover about 14 square meters, and the larger the place, the more serious the pollution, it is necessary to add a few more cans in an appropriate amount. I have come to buy everything, and don't be stingy in terms of quantityIt's a matter of personal safety(It's not that the family doesn't have this condition).
Recommended at homeEvery room, in the car, at the deskAnd there's thatBathroomThe air circulation is inherently poor, and it is more likely to grow bacteria and mildew, and emit peculiar smells, so put them in a can.
Early detection, early replacement,The visual aldehyde removal jelly makes people breathe with a special sense of security!
Whether you buy or rent the house you live in now, whether you have just moved or lived in it for more than ten years, the latent power of formaldehyde is unimaginable!Now hire a professional aldehyde removal team, one time is thousands, sometimes one is not enough, several times.
Finally, I would like to remind you again:The formaldehyde problem has never been alarmist.
Especially in winter, in cars and rooms, formaldehyde will only become more and more active. Putting it in the home and car not only removes formaldehyde and ensures indoor air quality, but also reduces various odors.
