In recent years, cancer, leukemia and other diseases have occurred frequently, and whenever I see such reports on news TV, I feel very sad, and the spearhead is pointed at decoration pollution.
This makes many owners of new house decoration panic!
Earlier, Xiao Pan, a 5-year-old girl in Jiangsu, had symptoms of dizziness and cough, and her family thought it was just a small cold, and she was not too nervousIt was to buy some medicine for her.
But after a few days of medication, Xiao Pan's condition did not improve, and his family was a little worried, so they took Xiao Pan to the hospital for testing.
The result was a bolt from the blue: Xiao Pan suffered from leukemia!
Xiao Pan's family found a professional testing agency to test their home, and the results showed thatThis renovation has ended, and it has been more than 7 years since I moved in, and the formaldehyde is still exceeded!
According to the "Standards for the Control of Indoor Environmental Pollution in Civil Construction Projects" (GB 50 325-20 20) promulgated in 2020, the safety standard for formaldehyde in civil housing is 007mg/m³。
The formaldehyde content in Xiao Pan's bedroom and other rooms in the home reached 0117mg m and 0109mg m, which is already in the category of excessive formaldehyde!
Therefore, Xiao Pan and her family have lived in a house with excessive formaldehyde for 7 years! Many people think that as long as the indoor formaldehyde concentration exceeds 01mg m is exceeded, if it is lower than this standard value, it means that there is no problem with indoor formaldehyde.
This is a wrong view, and everyone only has this understanding because the "Indoor Air Quality Standard (GB T188 83-20 02)" has relevant regulations, namelyUnder the condition of closing doors and windows for 12 hours, the average value of indoor formaldehyde cannot exceed 0 within 1 hour1mg/m。
However, this is only a reference standard, and it has a precondition that doors and windows are closed for 12 hours. In addition, the national mandatory standard "Civil Construction Engineering Indoor Environmental Pollution Control Code (GB50 325-20 20)" also clearly pointed out that under the condition of closing doors and windows for 1 hour, our residence, that is, a class of civil buildings, the formaldehyde concentration value is not higher than 007mg/m。
I want to remind everyone that there are many items in life that also contain a lot of formaldehyde, and even some items have a formaldehyde content that is better than that of decoration materials.
The survey found that as many as 70% of the families who moved into the house for 3-15 years still exceeded the formaldehyde standard! Most people are moving into the house is formaldehyde detection everything is normal, why does formaldehyde recur?
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 specializing in the study of the development law of formaldehyde mentions:Research from Yokohama National University 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.
1.Room Temperature:When the temperature exceeds 19, the formaldehyde volatilization rate rises by 0 for every 1 increase in indoor temperature4 times, especially when the temperature rises in summer or when heating in winter, the release is more violent, and the concentration will even exceed the usual 4 times.
This is the reason why formaldehyde is detected in autumn and winter.
2.Indoor Relative Humidity:The effect of humidity on formaldehyde is mainly because the urea-formaldehyde glue in the plate is produced by the polymerization reaction of urea and formaldehyde, and in the case of increased humidity and moisture of the plate, the urea-formaldehyde glue will decompose into urea and formaldehyde when exposed to water, thereby increasing the content of free formaldehyde in the plate, resulting in an increase in the content volatilized into the air.
3.Degree of loading of indoor materials:Although many people will use green building materials when decorating, there are still hidden dangers.
Because in the limited indoor space, even if the environmental protection indicators of the purchased building materials and furniture all meet the standards, the formaldehyde released by them will superimpose each other and make the formaldehyde concentration in the air exceed the safety standard.
4.Indoor air circulation:The effect of humidity on formaldehyde is mainly because the urea-formaldehyde glue in the plate is produced by the polymerization reaction of urea and formaldehyde, and in the case of increased humidity and moisture of the plate, the urea-formaldehyde glue will decompose into urea and formaldehyde when exposed to water, thereby increasing the content of free formaldehyde in the plate, resulting in an increase in the content volatilized into the air.
There are generally two statements about formaldehyde:Gases that are "odorless and pungent and pungent in their taste".
The irritation referred to here does not refer to how strong the smell is, the "taste" of formaldehyde generally refers toStimulation of human respiratory organs under conditions of high concentrations in space.
Human susceptibility to formaldehyde is extremely lowFormaldehyde odor threshold, that isThe lowest concentration that one can smell is 005～0.5 mg/m³, the general odor or aroma concentration reaches 0001mg m can be smelled by the human nose, and the olfactory threshold of formaldehyde exceeds the olfactory threshold of other odors by at least 60 times.
To put it simply: the formaldehyde concentration at home may have exceeded the standard, but we can't smell it. In another case, the pungent smell is not necessarily formaldehyde, but may be another gas.
In addition to concentration, different people have different sense of smell. There are institutions that have done this study specifically::The odor threshold of formaldehyde is judged by the sensitivity of different groups of people to odor
According to the test results, it can be seen that:There is a big difference in the sensitivity of different people to smellsNon-smokers are more sensitive to formaldehyde odors than smokers, especially non-smokers.
Formaldehyde exceeds the standard, and the body knows it early
The body reacts much earlier than the smell threshold compared to the "taste".
Most ordinary people have a formaldehyde concentration of 0Around 1mg m can cause discomfort, especiallyThe elderly, children, pregnant womenFor these sensitive groups, the formaldehyde concentration is 0Above 06mg m, there will be discomfort.
When you are newly renovated the place does not smell too much, but will feelSymptoms such as sore throat, cough, and choking, it may be caused by excessive formaldehyde, which is what we always say--Human formaldehyde detector.
As an insider, environmental experts pointed out that several inconspicuous daily necessities at home are large formaldehyde, and you must be careful when buying and using them.
1. With modeling cabinet door
Originally, I don't want to talk about the cabinet here, because of the plates, edge banding, and environmental protection, there are too many times to talk about them.
But helplessly, yesterday, there were people around me who chose this kind of molded cabinet door (also called blister door), and they didn't know that the substrate of this cabinet door was MDF.
A cabinet door is divided into two parts: the skin and the substrate.
Molded door (blister door) This is the material description of the outer bread crust, and the skin feeling film door, PET door, double veneer panel, and lacquer door are a class of things.
MDF is the same as particle board, multi-layer board, Osson board, and solid wood board.
Theoretically, molded doors don't have to be MDF, but the reality is that the molded doors we choose are all shaped cabinet doors, otherwise why don't we choose cheaper, usable double veneers.
If you want to have a shape, you can't use MDF, so the reality is: most of the molded doors we can buy are MDF as the base material.
There is also sad news, it looks refreshing and perfect handle-free solution - milled cabinet doors, and the substrate is mostly MDF (a small number of multi-layer boards).
The good news is: in fact, as a cabinet door, you don't have to worry too much about MDF, which has a tight package to limit the release of formaldehyde, and it is not a big problem.
2. Skirting boards
The general home improvement science will tell you that the baseboard is divided into: solid wood baseboard, PVC baseboard, and metal baseboard.
But it doesn't tell you that the solid wood is mixed with MDF baseboards.
The baseboard, no more than the cabinet door, needs to be cut in many places, so the formaldehyde problem will be a little more prominent than the cabinet door.
What's more urgent is this: MDF baseboard, this thing is afraid of moisture, and when it bubbles, it will be loose and fall off. Southern families, in particular, have to avoid this pit.
It is more recommended that the metal baseboard is better looking, easier to care for and hygienic, and durable, and the budget will be slightly higher.
3. Curtains and other fabrics
Curtains, I didn't expect this, in fact, any fabric things, including clothes, may exceed the formaldehyde standard when they are taken home.
Because there will be a series of industrial processes such as colorants, anti-wrinkle agents, etc.
But don't worry too much, formaldehyde, this thing can be dissolved into water, let's go home, wash these fabric things before using them.
4. Upholstered furniture
Upholstered furniture (upholstered furniture), the benefits are obvious, upholstered beds, more comfortable to lean, sofas, softer to sit on.
But at the same time, it also brings a disadvantage - it gives businesses an opportunity to take advantage of.
Often, when you look at a beautiful piece of furniture, when you open it and look closely, there are all kinds of problems.
For example, the upholstered bed, the side bed frame and the headboard are all made of MDF.
This phenomenon is very popular, regardless of brand and product grade, I went to the mall with my friends to see the bed a while ago, and asked for a soft bed with a price of 5000+.
I asked for a long time, and the sales couldn't tell what materials were used in it, and finally I was forced to find the introduction page on their home, and I looked at the material: the first layer of leather, silicone leather, solid wood, and MDF.
Tell me, is it a pit? Think about it, as long as the place where the back is leather, the place where the soft package, and the place where it is covered, it is all made of MDF (or MDF).
The bed is still conscientious, and it is all made of solid wood.
But the upholstered bedside table, this thing, is basically MDF.
Like this, the MDF that only bare the bottom surface of the drawer is already considered conscientious, and you also know that the side of the drawer, and even the inside of the cabinet, the conscientious will get you a bamboo veneer.
Bad heart, the inside is completely unadorned.
Similar to the bed, there is also a sofa, like this The bottom surface is sealed with MDF, don't touch it, the bottom surface is enough to get a glimpse of Sima Zhao's heart.
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 as a result, that's no joke!
After the beginning of spring, many people's new houses were renovated last winter, and even renovated around OctoberAs a result, formaldehyde still exceeds the standard. Why is that?
In fact, this is a common phenomenon, on the one hand, the temperature is low in winter, and the formaldehyde release is less, so the ventilation effect is not large. On the other hand, yesIn spring, the temperature rises, and more and more formaldehyde is released, that's why this is the case at home.
In the middle of spring, this season, the earth rejuvenates, the sky thunders, the grass and trees germinate, and everything wakes up. Although spring is beautiful, we are afraid of spring allergens, compared with spring allergens, formaldehyde release is more terrible, especially poor volatility, high precipitation of formaldehyde, benzene and other pollutants, will continue to affect the health of the whole family for many years!
Especially for people with weak resistance such as children, it is most likely to be caused, and formaldehyde is generally reachedBabies are susceptible to leukemia. And there is obvious damage to the human body, if you stay in a room with a high formaldehyde concentration for a long time, there will be dry eyes, cough or sore throat, so in ordinary life, you should avoid living in an environment with a high formaldehyde concentration.
We know that there is formaldehyde in newly renovated houses, where does formaldehyde come from? Like the most common one we buy at home, if it is wooden and uses a lot of adhesives, there will be formaldehyde!
At the same time, due to the different degrees of formaldehyde allergy in each person, some people are more serious, and some people may be mild.
Therefore, everyone should pay attention to the problem of formaldehyde, especially in the spring period, to prevent formaldehyde"Resurgence".
1. Always sneezing
If our child always likes to sneeze at home or at school, then be careful. Especially when our children were in good health when they were young, they basically did not get sick, they did not sneeze much, and now they are always sneezing, we must attach great importance to it, and when necessary, we must take the child to the hospital for examination, which is a sign of abnormality in the body.
2. The child has nosebleeds and bleeding gums
This is also terrible, our children generally only have nosebleeds in special circumstances, such as nosebleeds caused by external forces, such as nose being bumped, etc. But if our children start to have nosebleeds from time to time without any accidents, then it is very likely that there is too much formaldehyde content in the home, causing the children to have nosebleeds. We must pay attention to it, and we must also pay attention to the bleeding gums of children.
3. It is to avoid the decline of yi strength and often get sick
In the past, our children's physical resistance was very good, basically not sick several times a year, after living in a new house, our children's physical resistance decreased sharply, often sick, then we should pay attention to this may be caused by formaldehyde, we should pay great attention to it.
In the above cases, whether it is formaldehyde poisoning or not, it should beDeal with it in a timely mannerDon't be careless!
According to the 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.
Is this really 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".
After a period of time after the data were obtained, the experimental chamber was sealed again to observe the change of formaldehyde concentration.
After many tests, a general conclusion has been reached: in some cases, the formaldehyde concentration can be reduced to the national standard of 0 after about 10 minutes of ventilationBelow 1mg m3, if the decoration in the home is complex and the ventilation is not smooth, 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 exceeding the standard! Especially in some places that are difficult to ventilate near cabinets, corners, around beds, etc., the "poisonous gas" quietly released has been endangering our health!
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 [Activated carbon to remove formaldehyde discoloration balls]., I'll introduce you to its awesomeness!
This activated carbon removes formaldehyde and color changing ballsIt is a new aldehyde removal product launched by the Tsinghua Ph.D. team. Related R&D technologies are inYang regards a set of "Life Circle-Academicians Talk about Science and Technology".There have also been in-depth reports.
The R&D team members are all fromMaster's, Ph.D., and postdoctoral fellows from Hafo University and Tsinghua UniversityThe laboratory has more than 50 patents and is equipped with advanced testing equipment and space worth 4000W.
It can be said that in the field of aldehyde removal and air purification, it is truly the leader in the industry!
The principle of this formaldehyde removal color changing ball is not complicated:Physical adsorption, oxidative decomposition two-step removal of formaldehyde.
Step 1: Physical adsorption.
Black adzuki beans are natural sepiolite and active volcanic ores. It can absorb a large amount of harmful gases such as formaldehyde and benzene at one time.
Step 2: Oxidative decomposition.
Purple adzuki beans contain potassium high mengate, as well as a catalyst. Through a chemical reaction, the formaldehyde is absorbedDecomposes into water and carbon dioxide that are harmless to humans.
When the purple balls turn brown, it means that formaldehyde has been removed!
Let's see the technicians using a professional formaldehyde testerDo a formaldehyde removal test:
First, formaldehyde gas was injected into the test chamber with a content of 0508mg m, 5 times more than the safety standard!
Then put 100g of color-changing balls into the boxAfter 10 minutes, the formaldehyde content increased from 0508mg m drops rapidly to 0016mg/m³。
In just 10 minutes, a small bag of aldehyde removal color-changing balls can reduce the formaldehyde content in the box to 1 30.
When the particles all turn brown, it means that the service life needs to be replaced; If returnedPresence of red or reddish-black,That's itYou can continue to use it!
This color-changing ball alsoComes with a portable mesh bagIt can be replaced at any time according to the discoloration state, added at any time, and where the smell is, put it there!
Compared to the replacement of similar consumables,Chameleon balls are more convenient and inexpensiveAnd it can be discarded directly after use, and can be safely degraded by the soilEco-friendly and worry-free
As for the effect, you don't have to worry, there is a test result of the Guangdong Provincial Microbiological Analysis and Testing CenterThe aldehyde removal rate is as high as 98% in 24h!
to the sideFriends who are decoratingAlso recommended, he immediately bought two boxes. Unexpectedly, after using it, the formaldehyde concentration at home dropped to a safe range, and I was very happy in our groupCompliments, Amway
Not only to remove formaldehyde, but also to remove all kinds of peculiar smells at home can be easily dealt with here in activated carbon to remove formaldehyde and color-changing balls!
