houseFormaldehyde exceededIt is the increase in the number of cases that lead to the disease, which makes people talk about aldehyde discoloration, especially for families with children and pregnant women.
Regarding leukemia, ten years ago, it seemed very far away, and the probability of appearing in idol dramas was particularly high. However, in recent years, there has been more and more aboutChildrenThe news of leukemia became known.
At the same time, we know that the prevalence of childhood leukemia is also increasing. For example, the following case has attracted everyone's attention.
The new house is ventilated for 3 years, and the child is still"Sickness"?
Although Xiaobei is only three years old, her body is always sick, and her family just thought it was normal at first, so she only followed the ordinaryColdsto treat, until the child is serious, do not pay attention to it.
After Xiaobei arrived at the hospital, he was diagnosed with leukemia by the doctor, and the main reason for this was to liveIt has been ventilated for less than three yearsInside the house!
After getting sick, Xiaobei faced being quilted every dayDraw blood and prick needlesThe child's young age is a great pain. As a result, the family tested the air in the house and came to the conclusionFormaldehyde is seriously exceeded
In fact, some people just stay in the formaldehyde room for a few months, there is a high chance of leukemia, maybe everyone thinks that the chance of formaldehyde poisoning and leukemia is very small, butFormaldehyde is not only a new house that exists for decoration, but also a place where many people work and live, as long as there is a substance that can produce formaldehyde that can synthesize formaldehyde, formaldehyde will exist.
Indoor pollution hides in every corner you can't imagine, taking away your health and your family's health in a silent way all the time.
Formaldehyde in curtains, carpets and other products volatilizes relatively quickly, and can be released to a harmless level in about 3 years. The release of formaldehyde in floors, cabinets, wooden doors, adhesives and other products is relatively slow and will continue to be released.
So, how normal is the standard range of formaldehyde?
The standard range of formaldehyde varies by region and use. Here are some common formaldehyde standard ranges:
1. Chinese standards
The Chinese standard stipulates that the standard limit of formaldehyde in indoor air is 008mg m, this standard is applicable to all kinds of public places, residential and office places.
2. EU standards
The EU standard stipulates that the standard limit of formaldehyde in indoor air is 01mg/m³。This standard is applicable to all countries in Europe.
3. American standards
The U.S. Environmental Protection Agency (EPA) has set a standard limit of 0 for formaldehyde in indoor air1mg/m³。This standard applies to public places and residences in the United States.
In addition to national standards, different regions and industries also have different ranges of formaldehyde standards. For example, for the furniture industry, the standard range for formaldehyde emissions should be below E1.
This standard refers to the limit of formaldehyde emission in furniture, and if it exceeds this standard, it will cause harm to human health.
1. Sexual illness at home
When a family lives in an environment with serious formaldehyde pollution, they will be affected by formaldehyde, so they will have uncomfortable symptoms at the same time. Therefore, as long as you pay more attention after moving in, even if the formaldehyde exceeds the standard again, it can be found and treated in time.
2. Discomfort in the throat and nose
Experts advise that formaldehyde is a colorless, odorless and strongly irritating gas. Therefore, when we breathe, it will directly irritate the mucous membranes of our throat and nose, and then there will be cold-like reactions such as sneezing and coughing.
3. Inexplicable cold and fever
Generally, we have a cold and fever because of a cold, but did you know that formaldehyde toxicity also has a cold and fever?
If we wake up in the morning and often feel dizzy and dizzy, as well as the symptoms of cold and fever, then we can consider whether it is excessive formaldehyde.
4. Itching and rashing
If you find that you or your family members have red bumps and itching on your body after living in a new house for a period of time, it may be caused by excessive formaldehyde. Because ** is the first medium of contact with the air, and it is also the most honest "body guard".
In the above cases, whether it is formaldehyde poisoning or not, it should beDeal with it in a timely mannerDon't be careless!
I can often see that everyone has some experience in cleaning in the background, and they will leave a message to recommend some useful products, such as the magic wipe, but they are immediately reminded: there is formaldehyde, don't use it!
Because it has been exposedFormaldehyde contentIf the standard is exceeded, there will be residue after several washes.
Combined with the scenarios that everyone uses, it is very risky.
Hand holding wipe something:Formaldehyde direct contact**;
Put it at home:The formaldehyde released may be inhaled by babies and adults;
Used to wash dishes:There will be formaldehyde residues on the tableware, and there is a risk of ingestion.
This looks very dangerous, see what the experts say!
Experts have something to sayThere are many aliases for the Magic Rub: Kling Rub, Magic Sponge, Magic Nano Rub, Nano Sponge Rub, and so on.
But the material is melamine resin foam, also called melamine-formaldehyde resin foamA polymer obtained by the reaction of "melamine" and "formaldehyde".
It sounds scary, but when manufacturing, the production standards are strictly followed, and the product will not exceed the formaldehyde standard.
The reality is,Most consumers have no way of knowing how it is produced, so it is advisable to buy with caution
In this way, it seems that it is not only a small magic wipe, but also some kitchen cleaning products that we actually find difficult to ensure its quality, so we do it dailyHow to buy effective and safe kitchen cleaning productsThis?
After referring to the recommendations of the Provincial Quality Supervision Bureau and consulting experts, we have compiled 4 suggestions:
1.Look at the packaging. Choose the logo pattern with clear handwriting and complete label information. (There is a production license, product standard number, manufacturer name, address, net content, production batch number or production date and shelf life or expiration date, instructions for use, etc.).
2.Try to buy in large shopping malls, supermarkets, and formal e-commerce channels. (The quality of well-known brand products is relatively stable and reliable, and the performance is good).
3.Try to choose some natural extracts, do not contain phosphorus and organic volatiles, and at the same time pH neutral products, so that the damage to the environment and ** is smaller, and the damage caused by formaldehyde can be reduced. (Generally, there will be a claim on the product packaging).
4.Pay attention to the scope of application of the product and choose the appropriate washing product. (Generally, the product packaging will indicate whether it is suitable for ceramics, plastics, wood, metal and other materials).
Many people think that formaldehyde is far away from us, but in fact, environmental experts as insiders pointed out: a few inconspicuous things in the house are formaldehyde households, and you must be careful when buying and using.
1. Wall glue
Nowadays, many people will choose some environmentally friendly coatings when decorating, thinking that this can avoid the existence of formaldehyde.
In fact, people who have decorated know that before brushing the paint, they have to scrape the putty, but they don't know that the putty is made of talcum powder and glue, and the glue is an important part of formaldehyde when applied to the wall.
The glue sold on the market is also different, there are hundreds of pieces, there are thousands of pieces, and formaldehyde is hidden in those poor quality glues.
2. Interior decoration textiles
Textiles that are in close contact with us every day also have formaldehyde, includingBedding, wall coverings, wallpaper, synthetic carpets, curtains and upholstered furnitureIn textile production, in order to increase wrinkle resistance, waterproof performance, and fire resistance, producers usually add some additives containing formaldehyde, which leads to the release of formaldehyde when these textiles are used.
Therefore, when some textiles are bought, they should be cleaned immediately and exposed to the sun, which can effectively remove part of the formaldehyde.
3. Oil-based latex paint
Oil-based latex paint contains a lot of formaldehyde, and if oil-based paint is used during decoration, formaldehyde will be difficult to volatilize in the new home.
Therefore, do not use oil-based paint to paint the wall, try to use water-based topcoat and primer.
4. Inferior fabric sofas
After decorating the living room, everyone will definitely buy a sofa. Now the fabric sofa in Europe can be said to be out of order. However, you should not know that the cloth and wood of this sofa will volatilize formaldehyde for a long time.
In order to make the sofa fabric more wear-resistant and durable, merchants will add formaldehyde to increase the resistance of the fabric. The wood of the basic frame of the sofa is usually made of compressed board, and a lot of glue and formaldehyde are used in the production process.
If you also have these things at home, it is recommended that you throw them away, because these things are "formaldehyde sources"! After all, the formaldehyde release cycle is as long as 15 years, and if you accidentally get formaldehyde poisoning, it's no joke! What harm formaldehyde can cause to children?
According to China's epidemiological statistics, the natural incidence of leukemia is 3 per 100,000, and about 40,000 new leukemia patients are added every year, of which 50% are children, and most of them are children between the ages of 2 and 7.
Home renovation leads to indoor environmental pollution, which is considered to be the main reason for the increase in urban leukemia children!
According to the survey, children are more vulnerable! There are several reasons for this:
1. The molecular weight of formaldehyde is larger than the average amount of air, so formaldehyde is mainly concentrated in the space range of 1 meter on the ground, which happens to be the main respiratory zone of infants and young children;
Second, when quiet, the air inhalation of infants and young children is twice that of **, so infants and young children inhale much more formaldehyde than **;
3. Infants and young children have immature physical function development and low resistance, so they are most likely to become the target of formaldehyde.
Every year, there are many examples of formaldehyde poisoning in children due to decoration pollutionThis is because there are many similarities between the early symptoms of formaldehyde in children and the symptoms of flu, which leads some parents to ignore their children's conditions, causing irreparable tragedy.
Not necessarily.
Many people think that the old house has been old enough for a long time, and even if there is formaldehyde, it should have volatilized early, but in fact, it is not. Toxic and harmful gases such as formaldehyde in synthetic sheetsSustainable release, some up to 3 years or more.
In general, in a long-term environment, the formaldehyde content should not exceed 003 ppm, and some experts have tested an old house, formaldehyde as high as 022 ppm due to the use of inferior finishing materials and the lack of ventilation in the room. After testing, ventilation is the most effective way to remove formaldehyde, but if the decoration materials are not good, even if it is dried for several months or years, it may still exceed the standard!
1. What is volatilization?
Let's not look at how the temperature value of 19 comes about, but first look at the phenomenon of volatilization.
Volatilization, which refers to the free dissipation of molecules of a substance to the surroundings, moves freely, and is not affected by temperature, it can be either liquid or solid.
For example, a glass of water will volatilize at any temperature between 0 and 100, even if it freezes below 0!
Science refutes rumors:Volatilization has nothing to do with the temperature, and it would be wrong to set a temperature limit for volatilization!
2. Why 19?
Why do so many so-called "experts" on the Internet agree that the temperature value is 19?
The direct explanation of a large number of online articles is: the boiling point of formaldehyde is 19, and formaldehyde will not volatilize if it is lower than 19.
After data checking,The actual boiling point of formaldehyde is -195℃What does this mean? As long as the temperature exceeds -195. Formaldehyde is already boiling, and at this time formaldehyde is already in a state of rapid volatilization, rather than just beginning to volatilize.
And the so-called "formaldehyde will only volatilize when the room temperature exceeds 19" is very likely to be a copywriter will -195 It was misspelled as 19, and many peers made false rumors in unclear circumstances, and therefore compiled a set of self-considered "effective" formaldehyde removal methods.
The so-called Internet celebrity [smothering method to remove formaldehyde].
Science refutes rumors:The actual boiling point of formaldehyde is -195 ,19 only volatilized is pure misinformation! 3. The formaldehyde release at a temperature of 19 is accelerated
Indoor formaldehyde will be released faster as the temperature rises. The real reason is that one of the sources of indoor formaldehyde release is the board used in decoration and furniture, and most of the formaldehyde in the board is in the adhesive.
At present, the most widely used viscose in the production of man-made panels is urea-formaldehyde resin, and the unstable groups (such as free hydroxymethyl, hemiacetalized hydroxymethyl, and hypomethyl ether bonds) after curing are easy to release bound formaldehyde under compression.
In addition, the decomposition of the hypomethyl bonds under acidic conditions will also decompose and release formaldehyde.
Since the reaction of formaldehyde release is an entropy increase endothermic reaction, with the increase of temperature, the equilibrium moves positively, and the formaldehyde concentration increases, resulting in an increase in the indoor free formaldehyde concentration.
On the other hand, the increase in temperature will speed up the reaction speed, which is manifested in the increase of formaldehyde release rate of the board or floor.
A large number of experiments show that the formaldehyde release is relatively low when the formaldehyde is lower than 19, and the release is accelerated when it is higher than 1919 is more like a turning point where formaldehyde release accelerates
In addition, the increase of relative humidity causes the weakly acidic water vapor in the air to react with the free dimethyl alcohol oligomers in the viscose to form formaldehyde, and at the same time promotes the release of formaldehyde in the board. This is the reason why the humidity increases and the formaldehyde release accelerates.
The volatilization of formaldehyde is an uninterrupted process, and the higher the temperature, the faster the volatilization, which is why formaldehyde is raging in hot weather.
But it does not mean that formaldehyde does not volatilize at low temperatures, but volatilizes slowly, which we are not easy to detect.
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 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 if you put a pot of green algae in a room on the 100th floor, you 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.
According to relevant research, 80% of customers believe that ventilation can effectively reduce formaldehyde concentration, and the vast majority of people believe that opening windows for a few hours a day is enough.
However, this is not the case
The relevant experiments are as follows: firstly, the formaldehyde release source is enclosed in the experimental cabin, and the formaldehyde concentration in the experimental cabin is kept at 0 after stabilization2mg m3 and maintain the temperature at 25 degrees.
Then open the two ends of the experimental cabin and place it in an outdoor environment to achieve "north-south ventilation".
Some time after the data is obtainedThe experimental chamber was sealed again and the formaldehyde concentration was observedchanges.
After many trials, a general conclusion was reached: in some cases,After about 10 minutes of ventilation, the formaldehyde concentration can be reduced to the national standard of 01mg m3 or less,
If the decoration in the home is complicated and the ventilation is not good, the time will be longer.
After closing the doors and windows, the original formaldehyde concentration will be reached again in about 30 minutes.
Even if we use long-term ventilation to remove formaldehyde, this is still far from enough, because when ventilating, formaldehyde is released from the furniture, which leads to a small amount of indoor formaldehyde has been in a state of small exceedance! EspeciallyNear the cabinet, in the corner, on the bedSurrounding areas that are difficult to ventilateFormaldehyde will be quietly released and endanger our health
1. Opening the window for ventilation cannot blow every corner of the home, so it is easy to leave formaldehyde dead corners;
2. Secondly, ventilation to remove formaldehyde is easily limited by the weather, and the effect of aldehyde removal is not stable;
3. The release of formaldehyde is uninterrupted 24 hours a day, although a certain amount of formaldehyde can be removed by opening windows for ventilation, but the man-made plates, textiles, wallpaper and wall cloth and other items at home are still being released continuously.
Once the window is closed, the indoor formaldehyde will accumulate again, causing the indoor formaldehyde to exceed the standard again;
4. Formaldehyde has a long release period, so even if it is ventilated for 1 year, formaldehyde cannot be completely removed, let alone a few months?
Therefore, it is very impractical to rely only on ventilation to remove formaldehyde
For the health of ourselves and our families, we must not ignore formaldehyde If we want to remove formaldehyde safely and efficiently, in addition to daily ventilation, it is best to match a professional player!
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 oneRemove formaldehyde jelly!
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 ability to decompose 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 room 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 perspective: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, basically 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 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, the appropriate amount of more cans should be added. 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,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 the heating season, formaldehyde will only become more and more active in cars and rooms. Putting it in the home and car not only removes formaldehyde and ensures indoor air quality, but also reduces various odors.
