Determination of formaldehyde emission for wood flooring with non-destructive method and dryer

Taking "dryer method"as the foundation,the authors designed a non-destructive wood flooring formaldehyde releases device and established a non-destructive method.This method could cut down the process of board side sealing before determination of wood flooring formaldehyde,and reduce the accidental errors caused by specimen preparation,which could more truly reflect the formaldehyde release of artificial floor in the indoor air.The comparison experimental results show the formaldehyde release determined by non-destructive method proposed in this paper is lower than but relative to that by the drying apparatus method,the ratio is about 1.44,and the trends are consistently.The results of the two methods are mutually transformational.Thus,the non-destructive method can test the formaldehyde releases of wooden floor without destroy.
