How common is formaldehyde exceeding the standard after the renovation of new houses?
Many people will always have luck after the decoration of the new house, thinking that their home is high-quality decoration materials, and there should be no excessive formaldehyde, and they can move in directly without removing formaldehyde.
CCTV has conducted a sampling survey on newly renovated residential buildings in mainland China, and the sampling data shows that the formaldehyde excess rate of newly installed residential buildings in mainland China is as high as 70% to 80%, which is shocking.
In fact, even if we completely use safe and up-to-date decoration materials, there are too many materials used in the decoration of new houses, and due to the stacking effect, there will still be excessive formaldehyde problems.
Many people think that the formaldehyde in the new house is mainly caused by decoration materials, especially the latex paint contains formaldehyde, so if you want to avoid excessive formaldehyde, you should not apply latex paint as much as possible, and avoid excessive decoration.
In this regard, industry insiders said that simple installation can indeed effectively reduce the degree of formaldehyde exceedance, but the formaldehyde is not simply latex paint and other decoration materials, there are many release sources, and even some release sources contain more formaldehyde than latex paint.
Among the various formaldehyde emission sources in life, most of them contain formaldehyde in wood products made of MDF, composite board and particle board. In real life, we need to use too many supplies of this kind of board, and the amount is very large, such as furniture, beds, wooden floors, desks and bookshelves, etc., it is almost difficult to avoid excessive formaldehyde.
In addition, this kind of wood products also has a characteristic, that is, its release cycle is particularly long, such as latex paint and other decoration materials, its release cycle is about 3 to 5 years, but the release cycle of this kind of wood products can reach 7 to 12 years. In other words, if effective treatment measures are not taken, the problem of excessive formaldehyde will still exist even if you live for several years.
It is precisely because of this that industry insiders remind everyone that after the new decoration of the house, effective treatment measures must be taken, otherwise it will bring a huge threat to our health.
What will happen if formaldehyde is not treated after the renovation of the new house?
Although many people know that formaldehyde is harmful to health, there are still some friends who are in a hurry to move into a new house, which has just been renovated and has not yet dealt with formaldehyde.
In this regard, we should remind everyone that formaldehyde is particularly harmful to human health, if you live in an environment where formaldehyde exceeds the standard for a long time, it is likely that there will be formaldehyde poisoning symptoms such as dizziness, headache, nausea and vomiting, chest tightness and cough, and even cause cancer, leukemia and other malignant diseases, especially to the health of infants and young children.
Don't think this is alarmist, every year in the mainland infants and young children suffering from leukemia case reports are not uncommon, in the actual investigation process, people found that many children are directly related to the cause of formaldehyde exceedance.
It is precisely because of the super carcinogenicity of formaldehyde that as early as 2017, the World Health Organization included it in the list of a class of carcinogens.
Seeing this, do you dare to ignore the problem of excessive formaldehyde? Do you dare not remove formaldehyde after decoration?
In fact, the formaldehyde treatment of new houses is not difficult, even if we do it ourselves, we can easily do it, the following is a specific operation method, you can refer to it:
1. Control indoor temperature and humidity
The release rate of formaldehyde from indoor release sources has a great relationship with temperature and humidity, because the boiling point of formaldehyde is only 19.5 °C and is easily soluble in water, so the higher the temperature and the greater the humidity, the faster the release rate.
Experimental data show that the volatilization rate of formaldehyde increases by 0.4 times for every 1°C increase in temperature, and when the indoor temperature reaches 28°C, the formaldehyde release rate will increase by as much as 1 times. In addition, when the indoor humidity is between 40% and 60%, the formaldehyde release rate will also be significantly increased, and it will not cause damage to decoration and furniture.
Therefore, we can promote the release of formaldehyde by controlling the indoor temperature and humidity, and the current season is in the middle of summer, the indoor temperature is high, there is no need to take the method of heating, if the temperature is low in winter, the air conditioner can be set to 26 °C, so as to achieve the purpose of heating.
In addition, humidification is simpler, put a basin of water or humidifier in each room, and remind everyone that the humidity should not be too high, 40% to 60%, so as not to damage the decoration and furniture plates.
2. Open windows for ventilation
After the first step of operation, the formaldehyde concentration value in the indoor air has reached a very high value, and formaldehyde mainly exists in the air in a free state, we can use the circulation of the air to open the window for 8 to 10 hours a day to effectively reduce the formaldehyde concentration in the indoor air.
If the ventilation effect of the room is poor, you can prepare a large fan to blow against the window, so as to effectively enhance the indoor air circulation.
Before the formaldehyde concentration reaches the target and moves into the new home, the first and second steps can be repeated. Pay attention to close the doors and windows before each operation, increase the humidity and temperature, let the formaldehyde be released into the indoor air quickly, and then open the window for ventilation for 3 to 5 days, and repeat the indoor formaldehyde concentration value several times can effectively reduce it.
3, Activated carbon
Activated carbon can adsorb formaldehyde in the air, is a very good formaldehyde treatment technology, because its adsorption range is very limited, so we can place it in wardrobes, bed cabinets, shoe cabinets and other small closed spaces for formaldehyde treatment. However, it is necessary to remind everyone that when the activated carbon reaches the saturation value, it must be replaced in time, 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, formaldehyde is particularly soluble in water, and we can take advantage of its characteristics to regularly wipe the surface of furniture with a wet rag, mop the floor with a wet mop, and wash curtains, sofa covers and other textiles with clean water, which can effectively remove the formaldehyde contained in it.
As long as we do the above 5 points when removing formaldehyde, it only takes 1 to 2 months to move in with peace of mind, which is particularly simple and fast. Here, I also wish everyone to move into their new home as soon as possible and enjoy a healthy and comfortable life, and I also wish all the children a healthy and worry-free happy growth!
