[ Chinese wardrobe network ] What kind of materials should be selected for Home Decoration? Zhao Yingfeng introduced that solid wood panels contain almost no formaldehyde, and children's rooms and cloakrooms can be considered. However, this kind of wood has a lower bearing capacity and more attention should be paid. Finished particleboard and fiberboard release the largest amount of formaldehyde due to the use of a large amount of urea-formaldehyde. The blockboard and plywood are relatively moderate, the load-bearing capacity is good and the amount of formaldehyde released is not too much. It is used most on the market today.
After the renovation, do you have to wait until you can stay? With qualified decoration materials, formaldehyde will not exceed the standard? Yesterday afternoon, Nanjing Quality Supervision Bureau released the results of indoor air quality testing. The reporter learned that 42 households participating in the test, 42 households were unqualified, because the formaldehyde was exceeded. Among them, the renovation completion time of 32 unqualified families was less than 6 months. In addition, places such as cloakrooms with small space, furniture gathering, and no ventilation are also prone to excessive pollution.
If the materials purchased are all qualified, there is no pollution.
The amount of release is “superimposed†and the formaldehyde is still exceeding the standard.
Formaldehyde is a Class I carcinogen. If the concentration exceeds the standard, it may cause redness, itchy eyes, throat discomfort or pain, dermatitis and other uncomfortable reactions. In order to avoid air pollution, many people will also pay attention to the purchase of materials that meet the standard requirements.
The use of each material is qualified, does not mean that it will not cause indoor pollution! Zhao Yingfeng, an engineer of the National Building Materials Center of Nanjing Quality Inspection Institute, said that the release of these single product pollutants may be up to standard, but they are densely placed in a limited space. The superposition effect of the pollutant release amount will increase the concentration of pollutants in the air, resulting in the indoor air quality not meeting the standard.
In this test, some residents chose to test the cloakroom. Such a closed space with a high density of furniture sheets has many unqualified test results.
Artificial board pollution
Solid wood board is the safest
In order to pursue beautiful and gorgeous interior decoration effects, some families use artificial panels, surface paintings and decorative patterns.
What kind of materials should I choose for home decoration? Zhao Yingfeng said that the solid wood board contains almost no formaldehyde, and children's rooms and cloakrooms can be considered. However, this kind of wood has a lower bearing capacity and more attention should be paid. Finished particleboard and fiberboard release the largest amount of formaldehyde due to the use of a large amount of urea-formaldehyde. The blockboard and plywood are relatively moderate, the load-bearing capacity is good and the amount of formaldehyde released is not too much. It is used most on the market today.
It can be seen from the cut surface of the wood board that the solid wood board is the most neat and complete wood. Particleboard is a variety of wood chips glued together with urea-formaldehyde.
Serious pollution within 6 months
Stay away from summer
However, no matter what kind of material you use, you have to "dry" for a while before you can move in.
The test found that among the 42 unqualified households, 32 were completed within 6 months, and 28 were completed within 3 months. The first six months after the completion of the renovation is a period of high concentration of pollutants, and it is also the fastest period of dissipation.
Due to the different situation of each family decoration, Zhao Yingfeng said that it will not be possible to generalize how long it will take to move in. “It is recommended that everyone stay in the summer, because the amount of formaldehyde released will increase in the summer under high temperature and high humidity.â€
Suggest
Frequent ventilation
Clean the air purifier regularly
How to ensure indoor air quality? Zhao Yingfeng suggested that you should choose a simple and simple decoration mode, often ventilation, which is conducive to the dissipation of indoor pollutants.
If the indoor air pollutants exceed the standard, not only must be diligently ventilated, but also some green plants such as spider plant, tigertail orchid and aloe can be placed at home to regulate and control. If you use an air purifier, be sure to choose a regular brand and clean it regularly.
The filter element of the air purifier is generally activated carbon. If the filter element is saturated, it will release the originally absorbed pollutants and become a source of pollution, causing secondary pollution in the indoor environment. Therefore, if the filter element is saturated, be sure to pay attention to replacement or treatment to maintain the purification effect.
