Formaldehyde emission behavior from wood-based materials in the long term

Abstract

It experimented to understand the long-term raduation characteristic of formaldehyde from a wood system material as follows.(1)A basic characteristic of desicator method is understood.(2)The material is gathered,and mearsured from an actual hiyse.(3)The outdoor exposure test is executed.(4)Formaldehyde radiation amount change in material processed because og high temperature and high humidity.The result.(1)When an initial amount of the radiation was large,the amount of the radiation was a decreasing tendency.(2)When the amount of an initial radiation was a little,the following amount of the radiation was also little during half a year.(3)In the material that had been gatheref from an actual house,there was a material that showed a high amount of the radiation.(4)Under high temperature high humidity condition of 60°C,the amount of the radiation has increased remarkably.
