On the Internet, we often hear such remarks, formaldehyde is everywhere in life, as long as there is formaldehyde, it may lead to formaldehyde poisoning, and even cause leukemia, cancer and other malignant diseases, so is this really the case?
In fact, there is no need to be so alarmed about formaldehyde, from a professional point of view, the harmfulness of formaldehyde is directly related to its concentration value.
If we live in the environment, the concentration of formaldehyde ≤ 0.08mg/m³, it will not have any effect on our health.
In fact, even if the formaldehyde concentration value is slightly higher than 0.08mg/m³, such as within 0.15mg/m³, the health impact on adults will not be too great, and it is also necessary to pay attention to opening windows and ventilating frequently. However, if there are infants and pregnant women in the family, they need to pay attention, even if the excess is not serious, it will bring huge safety risks to their health.
If the formaldehyde concentration is much higher than 0.08mg/m³, such as more than 0.15mg/m³, then we must take scientific measures to remove formaldehyde, otherwise it will seriously threaten our health.
In this regard, some netizens asked, can formaldehyde really cause cancer?
Formaldehyde is irritating, and has a destructive effect on the human nervous system and immune system, if the formaldehyde exceeds the standard in the environment for a long time, it is likely that there will be dizziness, headache, chest tightness, cough, nausea and vomiting and other formaldehyde poisoning symptoms, due to the destruction of the human immune system, there will also be a decline in immunity, frequent illness, and even cause leukemia, cancer and other malignant diseases, this situation is particularly significant in infants and young children.
In fact, in recent years, there have been many reports of leukemia in infants and young children, and some medical institutions have conducted in-depth investigations on the home environment of the children and found that the homes of these children have been renovated before treatment, and most of them are luxuriously decorated.
In life, even if formaldehyde exceeds the standard is not serious, it will have a huge impact on the health of infants and young children, which is directly related to the imperfect development of the immune system of infants and young children, and the distribution range of formaldehyde in the air is mainly at a height of 0.5 meters to 1.5 meters above the ground, completely covering the height of the respiratory zone of infants and young children, and it is also the case that formaldehyde has a particularly large impact on the health of infants and young children.
It is precisely because of the huge harm of formaldehyde and its super carcinogenicity that the World Health Organization included it in the list of carcinogens in 2017.
The phenomenon of excessive formaldehyde in new house decoration is particularly common, and the degree of formaldehyde exceeding the standard is also more serious, how should we remove formaldehyde?
Regarding the removal of formaldehyde in a new house, most people will take ventilation for two or three months or half a year before moving in.
Many people think that after ventilation for such a long time, the formaldehyde in the house should be almost dispersed, and even if there is, it is a very small amount, and it will not have any effect on our health.
In this regard, some industry insiders pointed out that formaldehyde in the air mainly exists in a free state, and frequent window ventilation can indeed effectively reduce the concentration of formaldehyde in indoor air, and it can also provide fresh air, which is also the main reason for everyone to open windows frequently in daily life.
However, we should remind everyone that the formaldehyde in the environment in our lives comes from the release source, and these release sources will continue to release formaldehyde to the air under the influence of temperature, humidity and other factors.
Category 1: Wood products
That is, wood products made of particle board, MDF and other materials, such as furniture, tatami mats, desks, wooden floors, etc.;
The second category: decoration materials
For example, decoration materials such as wallpaper, latex paint, sealant, paint, etc.;
The third category: other products containing more formaldehyde
For example, daily necessities such as carpets, curtains, sofa covers, mattresses, etc.
The release cycle of these release sources is particularly long, for example, wood products are generally 7 to 12 years, while decoration materials can also reach 3 to 5 years, and carpets are about 5 years.
Although ventilation can reduce the concentration of formaldehyde in the air, but there is no removal effect on the formaldehyde inside the release source, if the new house is decorated simply by ventilation to remove formaldehyde, it is a symptom but not a cure, the problem of excessive formaldehyde can not be completely solved, and potential safety hazards will always exist.
Therefore, if we want to solve the problem of excessive formaldehyde in new houses, we must start from the root cause, so as to perfectly solve the problem of excessive formaldehyde.
Of course, it is not difficult to do this, we can easily solve it by ourselves, and finally share with you the specific operation method, you can refer to it when removing formaldehyde:
1. Control indoor temperature and humidity
The boiling point of formaldehyde is only 19.5 °C, when the indoor temperature exceeds its boiling point temperature, the release rate of the indoor release source will intensify, the experimental data show that for every 1 °C rise in temperature, the release rate will be accelerated by 0.1 to 0.25 times, and when the temperature reaches 28 °C, the release rate of formaldehyde will be increased by as much as 1 times (relative to the 19.5 °C environment).
In addition, formaldehyde is easily soluble in water, so humidity also has a great impact on the release rate of formaldehyde, when the indoor humidity rises, its release rate will be accelerated, because humidity will break the dynamic balance of formaldehyde release, promote formaldehyde to be released from the release source faster, and dissolve in the air water vapor.
With these characteristics of formaldehyde, we can take measures to control humidity and temperature to promote formaldehyde release:
If the indoor temperature is low, such as winter, late autumn, early spring and other seasons, we can use heating, air conditioning and other equipment to control the indoor temperature, and place a basin of water and humidifier in each room to increase the indoor humidity.
If it's a hotter season such as summer, we don't need to control the temperature anymore, just put a basin of water or humidifier in each room.
However, we should remind everyone that the temperature and humidity should not be too high, the temperature should be between 26 and 28 °C, and the humidity should be between 40% and 60%, so as not to damage the furniture and decoration.
2. Open windows for ventilation
After the first step, the formaldehyde concentration value in the room will be particularly high, but they all exist in a free state, so we can take the method of opening windows to ventilate to reduce the formaldehyde concentration in the room, and the ventilation time is about 8 to 10 hours.
If the indoor ventilation effect is not very good, you can use a large fan to blow against the window to enhance indoor air circulation and quickly reduce the formaldehyde concentration in the indoor air.
The above two steps and repeated operations, close the doors and windows before each operation, then increase the temperature and humidity to let the formaldehyde volatilize, and then open the windows for ventilation for a few days, and then repeat the operation several times, the indoor formaldehyde concentration will be greatly reduced!
3, Activated carbon
Activated carbon can adsorb formaldehyde in the air, but its adsorption range is relatively small, we can put it in some small closed spaces with poor air circulation to remove formaldehyde, such as wardrobes, bed cabinets, shoe cabinets, etc. However, it should be reminded that activated carbon has a saturation value, and it is recommended to replace it every 5 to 7 days.
4. Photocatalyst deep formaldehyde removal
This step is the core link of the whole indoor formaldehyde removal, and it is related to whether we can completely eliminate the risk of excessive formaldehyde, so we must do a good job in this link.
In this link, we need to use photocatalysts, which are the technical products that we know can really solve the problem of excessive formaldehyde from the root. Here it is recommended that you choose Yiya formaldehyde deep remover, many decoration companies and formaldehyde treatment companies will use it in formaldehyde treatment, and the recommendation rate in the industry is very high.
Yiya formaldehyde deep scavenger belongs to a new generation of nano photocatalyst, which is not only simple to operate, does not rely on the light source, but also has stronger permeability, can penetrate into the release sources such as MDF, particle board, wallpaper in a short time, and independently capture and decompose formaldehyde, benzene, TVOC and other harmful substances, with an aldehyde removal rate of more than 97%, which can truly solve the problem of excessive formaldehyde.
Some users share their own experience, spraying twice a week, insisting on one month, the indoor formaldehyde concentration value can be quickly increased from 0.4mg/m³ to 0.02mg/m³, which is particularly efficient and fast.
5. Formaldehyde removal for textiles
As we mentioned earlier, curtains, sofa covers and other textiles also contain a lot of formaldehyde, for these textiles that can be cleaned, we can use the water-soluble characteristics of formaldehyde to remove formaldehyde, soak it in clean water, fully dried, and repeat 2 to 3 times.
As long as you do the above 5 steps when removing formaldehyde, it only takes 1 to 2 months to completely solve the problem of excessive formaldehyde. Finally, I wish you all a healthy and comfortable life, and a healthy and happy day!
