Indoor formaldehyde pollution is extremely harmful to humans. Especially the newly renovated new houses have a high formaldehyde content, and they usually take a period of drying before they can move in. Today I will summarize the best ways to remove formaldehyde in new houses.
What is formaldehyde?
I heard that formaldehyde has been around for so long. What is formaldehyde? What is the harm to the human body? Formaldehyde is a colorless gas with a pungent odor. The harm to the human body is mainly manifested in:
1. Stimulation to the skin and mucous membranes. Direct contact with the skin of formaldehyde may cause allergic dermatitis;
2. Irritating to the respiratory system. Inhalation of high concentrations of formaldehyde may cause bronchial asthma;
3. Abnormal function. The affected include olfactory function, liver function, lung function;
4. When the indoor formaldehyde exceeds 0.5 mg/m3, it will irritate the eyes and cause tears.
Formaldehyde harms the human body in various ways, and indoor pollution is the main way. Therefore, you must check the indoor formaldehyde content before moving in, and then prescribe the right medicine.
formaldehyde detection.
The formaldehyde in the residence mainly comes from the paint, paint, plywood, fiberboard, particleboard and other artificial boards in the decoration materials and furniture. Before moving in, ask a professional to check indoor formaldehyde. The results refer to " indoor air quality standard ".
Third, the method to eliminate formaldehyde.
The commonly used methods to remove formaldehyde in households include ventilation and drying, plant decontamination, activated carbon adsorption and air purifier treatment.
1. Ventilation and drying method: After decoration, open doors, windows and cabinet doors to reduce the formaldehyde content through air circulation. But it takes a long time for this method to be used alone, and formaldehyde can be removed for more than 3 years;
2. Air purifier treatment method: air purifier by motor, fan, air Filters and other systems are used to circulate indoor air through the motor and fan in the machine, and the contaminated air is removed or adsorbed by various pollutants through the air filter in the machine. Generally speaking, the purification effect of air purifier treatment method is better, especially active air purification, which can make indoor air reach the standard of healthy air;
3. activated carbon Adsorption method: Activated carbon is used to remove formaldehyde. It mainly depends on the well-developed pore structure and surface area of activated carbon, which can greatly contact the surrounding air and adsorb pollutants into the voids. Therefore, the greater the surface area of activated carbon,
The more developed the pore structure, the stronger the adsorption capacity; The purification ability is very weak. And when the indoor formaldehyde concentration is high, it can also cause damage to plants. Therefore, after using the above three methods, you can place tigertail orchids, spider plants and other duties indoors. Long-term use of air circulation method can not only purify indoor air, but also achieve good decorative effects.
There are several ways to remove formaldehyde in a new house. In fact, it will be better if the combination of several methods is not independent of each other. , If you have any good way to remove formaldehyde, please leave a message to share.
