Abstract:
Objective To explore the removal effects of formaldehyde from indoor air and plywood by a formaldehyde-cleaning agent. Methods (1)experiment on removal of formaldehyde in indoor air: 2 newly decorated office rooms were selected, the indoor air was treated by formaldehyde-cleaning agent in one test room, and the other was used as control. After treatment, the concentrations of formaldehyde in two office rooms were measured and compared between them. (2)experiment on the removal effects of formaldehyde in plywood. The plywood samples were selected and divided into two groups, one was treated by formaldehyde- cleaning agent as test group, the other as the control. The emisson of formaldehyde from plywood was measured and compared between two groups. Results The removal efficiencies of formaldehyde in indoor air were 82.94%, 91.43%, 95.69%, at the 24th, 48th, 72th hour after the treatment of formaldehyde-cleaning agent respectively. The formaldehyde concentration in indoor air of test room met the requirement of the national standard after 72h-treatment of formaldehyde-cleaning agent. The removal efficiencies of formaldehyde emitted from plywood were 84.71%, 90.55%, 90.96% at the 24th, 48h, 72th hour after the treatment of formaldehyde-cleaning agent respectively. The emission amount of formaldehyde from plywood met the requirement of the national standard after 24h-treatment of formaldehyde-cleaning agent. Conclusion Formaldehyde-clearning agent presented significant removal effects on formaldehyde from indoor air and plywood.
