Decoration After the renovation of the new house, everyone must want to move in as soon as possible, but it is recommended not to be in such a hurry, because the formaldehyde problem cannot be ignored! Formaldehyde exceeding the standard is a common problem after the decoration of many homes or corporate offices, and only when the indoor formaldehyde concentration meets the *** standard, you can move in!
Formaldehyde is a colorless, irritating substance, which is volatile at room temperature and will accelerate its volatilization with the increase of temperature.
Now the materials used in decoration, as well as man-made panel furniture, will contain formaldehyde, and it will take 3-15 years for formaldehyde to volatilize and clean!
However, it is important to understand thatIt is not that you can only wait until there is no formaldehyde in the room to move in, as long as the formaldehyde content in the air can be stably maintained below the *** standard.
Regarding the indoor formaldehyde content limit regulations, the state has issued corresponding policy documents, mainly the "Indoor Air Quality Standard (GB T 18883-2022)", which will be officially implemented in February 2023, which is a recommended standard.
Under the condition of 12 hours of confinement, the formaldehyde content in the indoor air should be 008㎎/m³！This is a bit stricter than the old standard, and families are advised to follow this standard.
Since formaldehyde cannot be seen or touched, if it is perceived by the human body, when it can be detected, it means that the formaldehyde exceeds the standard. Therefore, it is better to take measures to get tested.
1. Measure formaldehyde by yourself. You can use a formaldehyde self-test box or a handheld formaldehyde detector, the advantage is that it is cheap and simple to use, and the disadvantage is that the detection accuracy is not high, which is for reference only.
2. Entrust a professional organization to test. One is the formaldehyde detection service provided by a professional formaldehyde removal company (using a high-precision detector, which can produce results on the spot), and the other is to find a CMA professional institution for testing (sending a professional laboratory for testing, and the results are slow). The advantage is that the detection results are more accurate, which is convenient for yourself; The disadvantage is that the cost is higher, and the cost of CMA testing is relatively higher.
Don't panic if indoor formaldehyde exceeds the standard, you can remove formaldehyde with the right method!
1. Open windows for ventilation
The most common and simplest way to remove formaldehyde is to open the window when the weather is fine, and use the natural circulation of indoor and outdoor air to achieve the effect of reducing indoor formaldehyde content.
Although this method is simple and affordable, it takes a long time to be alone, and it generally takes at least 3-6 months depending on the degree of pollution, ventilation conditions and other factors.
2. Professional governance
That is, entrust a professional formaldehyde removal company to come to the door, and they will use professional treatment technology to deal with it, such as: photocatalyst!
A photocatalyst is a photocatalyst that can decompose formaldehyde into harmless substances under the action of light. The construction personnel use professional equipment to spray the photocatalyst agent on the surface of furniture and other pollution sources, and the volatile formaldehyde can be sealed and penetrated and decomposed.
In this way, even if the renovation has just been completed, it can be moved in faster and safer after professional treatment. Generally, after professional formaldehyde removal company management, you can move in after about 3-7 days.
