| Abstract: | On the basis of introducing toxicity of formaldehyde and present state of controlling free formaldehyde emission from panel at home and abroad, this paper lay emphasis on discussing the research and development of BL-formaldehyde absorptive reagent, its reaction mechanism and application method, which pave the way for popularizing BL-reagent. Also,laboratory and production-scale experiment results of using BL-reagent in PB and MDF manufacture are presented, which show BL-reagent has remarkable effect of reducing free formaldehyde emission. |
