What should I do if the newly renovated rooms and offices are filled with the smell of formaldehyde? We all know that staying in an environment containing formaldehyde for a long time can cause death, especially for children with weak immunity, pregnant women, and the elderly. What are the hazards of formaldehyde? How to eliminate the harm of formaldehyde? Let's take a look!
1. What is formaldehyde?
Formaldehyde, also known as antaldehyde. Colorless gas with a peculiar pungent odor.
Second, formaldehyde
It's important to note that formaldehyde isn't just found in furniture, it's actually everywhere – in furniture, floors, clothes, food, and even cars. For example, formaldehyde in clothing is mainly used as a dye or to improve the anti-wrinkle and anti-shrinkage effect; Formaldehyde in food mainly exists in some foods that need to be soaked, such as beef shutters, duck paws, sea cucumbers, octopus, etc., because it can keep the surface color of water food smooth, enhance the toughness of taste and preservative, in fact, the state prohibits the addition of formaldehyde in food.
Formaldehyde is mainly present in indoor air, mainly in the following aspects:
Man-based panels such as plywood, blockboard, MDF and particleboard used for interior decoration. The adhesive used in the production of wood-based panels takes formaldehyde as the main component, and the residual and uninvolved formaldehyde in the board will be gradually released to the surrounding environment, which is the main body of formaldehyde in the indoor air.
Furniture made of wood-based panels. In order to pursue profits, some manufacturers use substandard boards, or use inferior glue when bonding veneer materials, and the formaldehyde in the board and glue is seriously exceeded, so it is likely that formaldehyde needs to be removed.
Other types of decorative materials that contain formaldehyde and may be emitted to the outside world, such as wall coverings, wallpaper, chemical fiber carpets, paints and coatings, etc.
3. The hazards of formaldehyde
When formaldehyde reaches a certain concentration indoors, people will feel uncomfortable, greater than 0Formaldehyde concentration of 08m3 can cause eye redness, itchy eyes, throat discomfort or pain, hoarseness, sneezing, etc. Newly renovated rooms have high levels of formaldehyde, which is a major cause of many diseases.
After the indoor formaldehyde concentration exceeds the standard to varying degrees, different symptoms can appear:
More than 20 50 times over the standard (2.).0-5.0 mg cubic meters) – our eyes will feel intense irritation.
More than 100 times (10 milligrams of cubic meters) - dyspnea may occur.
More than 500 times (50 milligrams of cubic meters) can cause critical illness such as pneumonia and even death.
Fourth, how long is it appropriate for a new house to "dry"?
Some friends are not at ease, thinking that the longer the better, and some people even ventilate the new house for half a year to a year. Insiders said: the longer the better, in fact, formaldehyde can be 'lurking' in your decoration materials for ten to fifteen years, and it makes no sense to dry it for too long.
Generally speaking, according to the physical condition of adults, the new house can be moved in if there is no overly pungent smell after 3 months of ventilation, and for fragile children, the elderly and even pregnant women, it is best to keep the ventilation time for about half a year. And the indoor air quality should be measured.
There are also 3 issues that should be paid attention to when ventilating:
1. It is not that formaldehyde is dispersed quickly when ventilated all the time. Especially in winter, the low temperature will slow down the release of formaldehyde, it is best not to open the window at night, open one or two heating equipment indoors, so that the room temperature rises, so that the formaldehyde is released faster, and the indoor formaldehyde can be released more quickly when ventilated.
2. The ventilation time is best between 11 a.m. and 3 p.m. This time is the time when the outdoor temperature is higher, the sun is abundant and the air is drier, choose this time to ventilate, and the formaldehyde will be emitted faster.
3. Open the window to ensure the convection of air. It is best to open the windows on opposite sides according to the wind direction, so that the outside air can come in more easily and smoothly "replace" the indoor air.
However, it takes too long to ventilate and remove formaldehyde, so is there a faster and more effective way?
The following is a very good way to remove formaldehyde, which is the manganese carbon package adsorption method. Easy to use, inexpensive, convenient and fast.
Many people have given it a good evaluation, because it has indeed helped so many people solve the formaldehyde in their homes.
It only needs to be placed in the drawer of the newly bought furniture in the home, which can be very simple, and there is no need to open the window for ventilation.
And it's been researched by some people with a relatively high level of knowledge, and they are people who specialize in environmental problems.
So you can use it with confidence, don't worry about its effect, and don't worry about its safety.
After all, it is something that is placed around us for use, and if it is not safe, it will not be produced, so let us all use it.
Of course, it is also subjected to rigorous experiments and tests before production.
The manganese carbon bag was put in the middle of the experiment so that you could feel how quickly it worked.
This experiment is still relatively rigorous, strictly referring to the unsafe range value of formaldehyde, and then testing the effect of manganese carbon packets.
The formaldehyde value dropped rapidly at the first time, but it has not yet reached a safe range. In the end, it only took a few minutes to reach the safe range value, and the effect was relatively clear.
The effect is more realistic. In order to ensure our healthy body, we can usually put it around, as long as there is formaldehyde in the surrounding environment, it can be automatically adsorbed, which is very good.
When we can't remove formaldehyde, we can use this method to try it, and there is no loss.
Many people have used it, which means that it is really easy to use, so many people will recommend it. We don't worry about the environment in the home, just in the home in every furniture drawer in the empty space can be put a bag to solve the doubts in the heart. So, there are no security hazards.
If our car has just been bought not long ago, and there are a lot of unpleasant smells in it, you can also put two packs in it, which is more assured.
After putting two bags in the car, I was in a very relaxed mood when driving.
Because our driving environment also needs to be paid attention to, don't underestimate the short minutes or half an hour of driving. If it is a long time, it is also harmful to the human body, and the interior of the car also contains formaldehyde.
As long as it is wooden furniture, there will be a formaldehyde problem, don't think too much, put it directly to adsorb formaldehyde and solve the formaldehyde problem.
After all, formaldehyde exists in many places in the house, and we can't see it. Therefore, formaldehyde needs to be removed well. Manganese carbon packets can adsorb formaldehyde clean, which is protective of our health.
If you don't solve the formaldehyde problem of furniture, good furniture will be thrown away, it is a pity, even if you buy new furniture also contains formaldehyde, or the most important thing to solve the formaldehyde problem at one time.
And only when the environment in the home becomes safe, can we relax, read a book, be happier, and be more comfortable.
It shortens the formaldehyde release cycle, and we can move into the house of our choice as soon as possible.
