Dalian: National standards for formaldehyde testing and how much it costs

The standard range of formaldehyde is below 0.08. Formaldehyde testing is generally charged by points. How much does one point cost? If the requirements are not high, you can use a formaldehyde self-test box for sexual testing. Formaldehyde has a certain impact on the human body. Serious hazards, when formaldehyde is found to exceed the standard, it must be dealt with in time. I recommend several useful methods to everyone.

1. Ruishi

It has regular honeycomb-shaped voids inside. Its specific area is huge and it can efficiently adsorb formaldehyde. Its adsorption capacity is strong and can reach twice the level of traditional activated carbon. More than ten times, it not only has a large adsorption capacity, but also has an ion exchange function, which can decompose harmful substances such as formaldehyde into harmless carbon dioxide and water, and can be used for a long time without replacement. When selecting, please note that it is a gray ore with irregular shape, not round particles.

2. Open windows for ventilation

If you want to remove indoor formaldehyde and odor as soon as possible in a newly renovated house, the first thing to do is to open the windows for ventilation. While opening the windows, you can Open cabinet doors and drawers to dilute formaldehyde and discharge it outdoors through air convection. Although this step is simple, you must also pay attention to the weather conditions to prevent heavy winds and heavy rains from damaging the newly renovated home environment?

3. Plants

Choose plants that can absorb formaldehyde, such as pothos and aloe vera. , Chlorophytum and other plants can absorb a certain amount of formaldehyde pollution and can indeed remove formaldehyde. Placing some green plants in your new home can also beautify the room and freshen the air. However, the adsorption capacity of plants is relatively limited. If the formaldehyde concentration is too high, plants will wither and die.

4. Formaldehyde scavenger

Formaldehyde scavenger chemically reacts with formaldehyde under certain conditions to generate other substances that are not harmful to health, thereby reducing indoor pollution. Formaldehyde concentration. But it is also a chemical substance in itself, and if used improperly, it can also become another source of indoor pollution.

5. High temperature

Under high temperature, it can promote the conversion of bound formaldehyde into free formaldehyde and reduce the total content of formaldehyde, because formaldehyde penetrates deeply into the board, although it cannot be Formaldehyde is completely removed, but the effect is still very obvious.

In order to better reduce the formaldehyde concentration in the home environment, during the decoration process of new houses, try to control the quality of decoration materials and choose materials with relatively low formaldehyde content.
