One、How to remove formaldehyde from particleboard furniture
1、Ventilation and formaldehyde removal method
Formaldehyde is a gas, so ventilation can remove a portion of the formaldehyde from the air. By circulating indoor air, the concentration of harmful substances in the air can be reduced, thereby minimizing the harm to the human body. Indoor air is not only affected by formaldehyde, but long-term closure of windows and doors can also lead to a buildup of carbon dioxide, especially in winter when people tend to keep their doors and windows closed, preventing the circulation of indoor and outdoor air. To minimize the effects of formaldehyde, ventilation is an important step.
2、Activated carbon adsorption method
Activated carbon is a widely recognized and effective substance for removing toxins. Many masks and respirators utilize activated carbon as a raw material. Activated carbon is a non-toxic substance that does not contain any chemical additives. The physical properties of activated carbon include adsorption of odors, and formaldehyde is a gas. Therefore, activated carbon has a significant effect on adsorbing formaldehyde, and it can help remove formaldehyde from the indoor air within 72 hours.
3、Phytoremediation for formaldehyde removal
The method of using plants to remove formaldehyde requires that the formaldehyde pollution in the house should not exceed moderate levels. However, most homes have only light or moderate levels of formaldehyde pollution. When using plants to remove formaldehyde, achieving a reduction of three times the national standard can effectively remove formaldehyde. You can purchase different plants based on the size of the room. For example, you can place 1-3 pots of cacti in the bedroom, and 2 pots of pothos in the living room to effectively remove moderate levels of formaldehyde.
Two. How long does it take for high-density fiberboard to release formaldehyde?
1、The release of formaldehyde from furniture is a continuous process, and the release time varies depending on the source. Formaldehyde released from particleboard veneered panels typically lasts for more than 3 years, and in some cases, can exceed 10 years. Formaldehyde released from wall coatings can dissipate within 7-15 days. Formaldehyde released from wallpaper adhesives typically lasts for more than 18 months. Formaldehyde released from large-panel boards typically lasts from 15 months to 5 years.
2. Generally, newly renovated houses release formaldehyde over a period of approximately three months due to daily ventilation. If you are concerned, it is advisable to purchase a formaldehyde detection kit to test the indoor formaldehyde levels. After moving in, it is essential to maintain good ventilation.
3. According to national standards, particleboard can be classified into E0, E1, and E2 grades based on its free formaldehyde content. E2-grade particleboard has a formaldehyde emission rate of ≤5mg/L; E1-grade particleboard has a formaldehyde emission rate of ≤1.5mg/L, and can be directly used in interior decoration; E0-grade particleboard has a formaldehyde emission rate of ≤0.5mg/L. Consumers should prioritize purchasing particleboard with low formaldehyde emission rates, as these products are safer.
