E0, ENF, F 4-star, and P2,which is more environmentally friendly? How to detect the environmental protection level of Medium fiber board E0, ENF, F 4-star, P2, and which one is higher? 1： Testing method for environmental protection level of fiberboard: There are three ways to test the environmental protection level of MDF board : dryer method, climate chamber method, and drilling extraction method. The drilling extraction method is generally used for internal testing by sheet metal manufacturers and is rarely used for product testing and evaluation. Although all three methods of detection are used to detect formaldehyde, the experimental methods and scope of detection are also different. The detection data for the same board and different methods will definitely be different, and there is a significant difference in numbers. For example, using a dryer method to release formaldehyde: a 0.5mg/L board will d...
