Looking at the renovated new house everyone's heart is not super happy? After several months of busy homes have finally turned into dreams, the feeling of waiting to live in has already been written on the face. In fact, after the house is installed, there are many other matters needing attention. After all, today's renovations have been very different from those in the past. No matter what materials are used, glue will be used, and glue will be released. In the past, carpentry assembly techniques that did not use glue were commonplace, and now I would like to admire it. So you have to ask how long I can stay in a renovated new house. I will tell you that it is not so simple.
People now have a high awareness of environmental protection. New homes that have been renovated need to measure the concentration of formaldehyde every time. This awareness is particularly good, because everyone is finally beginning to realize that the indoor concentration of formaldehyde after renovation is harmful to people. Progress in consciousness is a good thing, but as a non-professional, it is still necessary to understand the ins and outs of formaldehyde.
What is formaldehyde?
Formaldehyde, as a chemical organic gas, can be regarded as one of the "first-line stars" because the information and reports on formaldehyde on the Internet are extremely rampant and can be seen everywhere. The search for “formaldehyde†in Baidu can retrieve as many as 90 million results, showing that the public’s “enthusiasm†for formaldehyde has reached a rare height.
If professionally asked what formaldehyde formaldehyde is, everyone may feel a bit dizzy.
In fact, as a chemical substance , formaldehyde itself has only its own attributes and is not good or bad. It is only used properly .
The public's negative perception of formaldehyde is mostly due to the individual's point of view. It has a strong individual color. In fact, although formaldehyde poses a serious threat to human health, it has many uses in many areas.
Chemical industry, wood industry, textile industry, and formalin anticorrosive solutions all require the use of formaldehyde. Therefore, the correct use of formaldehyde can bring a lot of excellent products to our production and life, so it is not necessary to mention formaldehyde again. Detested.
Why do people not know about formaldehyde and how to define excessive levels of formaldehyde?
99% of the public, after being in the house, because of the smell of pungent smell in the room, they believe that the excessive formaldehyde, need to remove formaldehyde, so many people began to check the Internet: how quickly in addition to formaldehyde, formaldehyde harm to the human body ... ... Many of the dangers of formaldehyde are alarmist.
However, one thing is certain: excess formaldehyde is indeed harmful to the human body.
In fact, formaldehyde is a colorless gas. When the content in the air exceeds the standard 3 times or more than 4 times, people can feel the irritation of formaldehyde. At this point, formaldehyde can cause damage to the body's mucous membranes. For example, the throat is uncomfortable and the eyes do not open. Of course, this is not the main way that formaldehyde harms human health. Formaldehyde is harmful to human health. After the main formaldehyde is inhaled into the alveoli, it can enter the blood and cause harm to the human body, such as causing baby distortion, cancer, and so on.
Formaldehyde is irritating, and it is necessary to reach a certain concentration. It does not mean that there is excessive odor in the home or formaldehyde. On the contrary, in the case of irritating odors in the home, only a small part is due to excessive formaldehyde, more because of the bitter almond flavor of benzene, the chemical fertilizer smell of ammonia, and the synthetic smell of airborne organic compounds (TVOC).
Of course, because of this, it can no longer be said that when the renovated new home has no irritating smell, the air quality in the home is up to the standard. In short, if formaldehyde exceeds the standard, it cannot be judged and judged by odor. It requires a professional inspection agency with CMA qualification to carry out testing before conclusion can be made.
Where does formaldehyde come from?
1. Artificial plate
At the time we used various types of man-made board, plywood, slender wood board, middle fiber board, particleboard, and other artificial board, formaldehyde was added to different degrees in the production process.
The urea formaldehyde resin adhesive with formaldehyde as the main component is toxic, but it has strong adhesiveness, and it also has the effect of strengthening the hardness of the plate and preventing pests and corrosion. In the production process of wood-based panels often used, so the plate is also a major reason for excessive formaldehyde in new homes .
2, indoor
In addition to man-made boards, furniture at home may also be one of the causes of excessive indoor formaldehyde concentrations.
The use of furniture made of wood-based panels, solid wood panels, etc., due to the addition of binders during the production process of the panels, the assembly of the furniture may also use adhesives, further increasing the formaldehyde content of the furniture. In addition to sheet metal furniture, some furniture and furniture also contain different levels of formaldehyde.
3, wall surface
If paint, latex and other wall building materials are not properly selected, it will also cause indoor formaldehyde content to exceed the standard.
Wall paint manufacturers on the market all claim to be “zero-formaldehyde productsâ€. In fact, the so-called “zero-formaldehyde products†do not exist. With current technology, it is still not possible to completely remove formaldehyde. Before purchasing paint products, ask the merchant for a product test certificate to see what the formaldehyde test item content is. According to the relevant regulations, the indoor formaldehyde concentration must not be higher than 0.08 mg/m2 (0.08 mg/m3). If the merchant refuses or can't take the test certificate, the environmental performance of the product can be imagined.
How long can a newly renovated home stay?
In general, after the renovation of new homes, it is best to open windows, ventilated and ventilated for more than 6 months. Everyone thinks that it is safe, but it is not. Studies have shown that there are five main pollutants such as formaldehyde, benzene, ammonia, volatile organic compounds, and radioactive cesium that are newly renovated and newly purchased. Uncontrolled control can harm the human body. In addition, the release cycle of decoration pollutants is very long, reaching 3 to 15 years. Moreover, the number of deaths caused by indoor air pollution in the country each year has reached 11 to 10,000 people, an average of 304 deaths per day. The death toll is second only to leukemia and is the second largest cause of death. Therefore, decoration pollution is called indoor "invisible killer", in which harmful substances on pregnant women, children and the elderly are more serious.
In addition, it is worth noting that the degree of emission of harmful gases is closely related to the temperature, and air conditioning in winter or summer will greatly affect the emission of harmful gases. How long can a newly renovated house stay? Three months? Six months? Not right! According to the actual situation to determine the time of check in.
Measured according to the indoor air detector, the air quality can meet the standard.
The best way to remove formaldehyde
1, window ventilation
To remove formaldehyde and odor in a newly renovated house, the first step is to open the window and open the derailed cabinet doors and drawers. By means of air convection, formaldehyde is diluted and discharged to the outdoors. Although this step is simple, but also pay attention to the weather conditions, once the wind and rain must be closed doors and windows in time, so as not to replace the newly renovated home environment.
In order to improve the ventilation effect, it is also considered to accelerate the indoor air convection by pressing a fan in the room and shaking the head mode.
2, place the activated carbon
After several days of window ventilation, formaldehyde can be effectively discharged to the outside, but the degree of residual formaldehyde is still high for some corners and densely covered areas. Therefore, you can use activated carbon package, with the use of natural Mayan blue air purifier, to adsorb the residual formaldehyde to remove the role of formaldehyde, the effect will be better.
Usually, the recommended amount of charcoal package is 15-20 packets (50g/bag) in a room of about 20 square meters, and drawers and cabinets can be placed in 1 to 2 bags depending on the size.
3, planting potted plants
The renovated new house can basically eliminate the formaldehyde odor by a series of measures, but the residual formaldehyde is usually very small or even unpleasant and lasts for 3 to 5 years. Therefore, it is advisable to buy some formaldehyde-removing plants such as Chlorophytum, Sansevieria, and aloe vera before or after the stay. These plants are not only easy to grow and care but also can effectively remove formaldehyde, which is a good choice for beautifying the home environment.
Chlorophytums usually contain 1 to 2 pots in one room, but it is not recommended to put them in the bedroom.
In addition, we can also try a professional addition to the formaldehyde company's services, real-time monitoring of dynamic data on formaldehyde density, to maximize the protection of family health.
Summing up: Today we have read how long the renovated new home stays in this article. The understanding of formaldehyde is even more. If your home has a similar situation, you may wish to dry it for some time. It is also OK to wait for the formaldehyde data to return to normal values.
