| Is activated carbon useful for removing formaldehyde? | |
| 2021-05-31 | |
| it works. Because activated carbon has strong adsorptive properties, it can absorb free formaldehyde in the air, but it cannot penetrate into furniture panels and solve the formaldehyde problem from the root cause. In addition, when the activated carbon is fully adsorbed, it should be replaced in time, otherwise it may cause desorption of pollutants and cause secondary pollution. Method to remove formaldehyde: 1. Ventilation method to remove formaldehyde This is the most commonly used method now, which can reduce harmful substances in the room through air circulation, thereby reducing the harm to the human body. In winter, people often close doors and windows tightly, making the air unable to circulate. This will not only increase the content of formaldehyde in the indoor air, but also continue to emit radon, and even endanger health. 2. Activated carbon adsorption method Activated carbon is a recognized drug addict. As long as two to three dishes are placed in each functional area, the indoor odor can be basically eliminated within 72 hours. This method can be selected for medium and low pollution, or the activated carbon can be used in combination with other chemical methods, and the comprehensive treatment effect is better. 3. If the pollution is not serious, the plant deodorization method can remove the plants in each room. Generally, in a room of about 10 square meters, two pots of 1.5 meters high plants need to be placed, or put on a spider plant with a strong adsorption function. Tiger skin. 4. Chemical sprays to remove formaldehyde are not only easy to cause secondary pollution during treatment, but also easy to damage the furniture, so you must be cautious when using it. |
