Many friends may not know that if the formaldehyde treatment is not done well after the decoration of the new house, the problem of excessive formaldehyde will still exist even if you live in it for 5 or 6 years.
In the mainland's "2020 National Home Environmental Protection Report", there are more than 60,000 family houses participating in the survey, and the survey results show that the formaldehyde excess rate has reached 31.3%, of which more than 15% have been occupied for more than 5 years.
Some friends may say that the decoration of my new house is made of high-quality decoration materials, which are very safe and will not have the problem of excessive formaldehyde.
In this regard, CCTV has also done an investigation report on the newly installed houses in the mainland, and the survey data shows that the formaldehyde excess rate of the newly installed houses in the mainland is as high as more than 70%.
At this time, some friends may ask, why is this happening?
In this regard, industry insiders pointed out that the reason why the phenomenon of excessive formaldehyde in family homes is becoming more and more common is directly related to our more and more luxurious decoration.
The reason for excessive formaldehyde is that the release source formaldehyde release is too large, and the reason for the excessive formaldehyde release is caused by too many release sources, here we divide the formaldehyde in life into three categories:
1. Wood products such as MDF, particle board and composite board
This kind of wood products are especially common in life, and there are many of them, such as furniture, beds, tatami mats, desks and bookshelves, dressers, wooden floors, etc. The formaldehyde content of this kind of board is particularly high, especially some inferior boards, which may only need a few pieces to exceed the indoor formaldehyde standard, not to mention so many wood products.
2. Decoration materials
This kind of material is also necessary for decoration, such as wallpaper, latex paint, waterproof glue, soft packaging, etc., this kind of decoration materials cover a large area, and it is also a common factor that leads to excessive indoor formaldehyde.
3. Other formaldehyde-containing supplies
This type of products covers a wider range, such as mattresses, carpets, curtains, etc., which also contain formaldehyde.
The formaldehyde in these release sources will not be released at one time, but have a long release cycle, such as about 7 to 12 years for wood boards, and about 3 to 5 years for wallpaper and latex paint.
After the renovation of the new house, the release state of these release sources is at its peak, coupled with the stacking effect, so it is particularly prone to the problem of excessive formaldehyde. If it is not properly treated, as long as the release cycle of these release sources is not reached, then the risk of indoor formaldehyde exceeding the standard will always exist.
Some friends will say that my new house has been ventilated for several months after renovation, and the formaldehyde has been dispersed and cleaned early, but the truth is not so simple!
Opening windows for ventilation is a common method for removing formaldehyde, and in fact, even professional formaldehyde treatment companies will use it, which shows that this method is effective.
The reason is also very simple, formaldehyde is released into the air in a free state, it can not only be directly inhaled into the body through breathing, but also flow with the flow of air, when the window is opened for ventilation, the outdoor fresh air will contain formaldehyde indoor air "squeezed" out, thereby effectively reducing the concentration value of indoor formaldehyde.
However, we should remind everyone that opening the window ventilation is not a cure for the symptoms, it can only target the formaldehyde in the air, and the formaldehyde in the release source is helpless, as long as the window ventilation time does not reach the release cycle of the release source, then the formaldehyde exceeding the standard will be repeated. Therefore, simply opening the window for ventilation for a few months cannot solve the problem of excessive formaldehyde.
So, how do we remove formaldehyde?
In fact, it is very simple, we don't need to spend thousands or even tens of thousands to find a formaldehyde treatment company to remove formaldehyde, you can easily do it yourself, and it doesn't cost much, let's share the specific operation, you can use it for reference:
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
Formaldehyde is particularly soluble in water, 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 clean curtains, sofa covers and other textiles with clean water, which can effectively remove the formaldehyde contained in it.
As long as the above 5 steps are done when removing formaldehyde, whether it is a new house that has just been renovated or an old house that has been lived in for many years, formaldehyde can be swept away in a maximum of 1 to 2 months.
Finally, I wish everyone to move into their new home as soon as possible, enjoy a healthy and comfortable life, and completely get rid of the trouble of formaldehyde!
