甲醛消除灵消除甲醛效果的实验研究

目的：研究甲醛消除灵对室内空气和木质板材中甲醛的清除效果。方法：(1)室内空气中甲醛的清除试验：选择新装修的办公室2间，1间经甲醛消除灵处理，1间不作处理，比较2个房间的甲醛浓度。(2)木质板材中甲醛的清除试验：采木质板材，1份经甲醛消除灵处理，1份不作处理，同时检测其甲醛释放量。结果经甲醛消除灵处理24、48、72h的房间空气中甲醛的清除率分别为82．94％、91．43％、95．69％，处理72h室内空气甲醛浓度达到国家标准；木质板材经甲醛消除灵处理24、48、72h甲醛的清除率分别为84．71％、90．55％、90．96％，处理24h后木质板材甲醛释放量达到国家标准。结论：甲醛消除灵对室内空气和木质板材中的甲醛均具有明显的消除作用。

Experimental Study on the Removal of Formaldehyde by Formaldehyde-Cleaning Agent

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.
