Improvement of Perforator Apparatus for Detecting Formaldehyde Emissions from Wood-based Panels
In order to improve extraction efficiency of perforator apparatus for detecting formaldehyde emissions from wood-based panels, the apparatus structure was improved. Testing results showed that extraction efficiency of the improved apparatus was significantly increased by reducing extraction time from 120 min to 60 min. And the absolute deviation, relative deviation and variation coefficient were0.4,0,.6 mg/100 g, 1.7%,2,.9% and 1.3%,1,.8%, respectively.
