When choosing Medium Density Fiberboard, pay attention to the following aspects
1. Look outside to see if its thickness and density are uniform, whether the corners are damaged, whether there is delamination, bulging, carbonization, etc., and whether there are loose parts or not.
2. When conditions permit, a small piece of medium-density fiberboard can be sawed and soaked in water with a water temperature of 20°C for 24 hours to observe the change in thickness, and at the same time, observe whether there is any snare bag on the board surface. The thickness changes greatly, and there is a snare pack on the board surface, which indicates that the board surface is poor in waterproofness.
3. Select a medium-density fiberboard with a low release amount. When selecting and smelling, select a medium-density fiberboard that has a low pungency. Because the greater the odor, the higher the amount of formaldehyde released and the greater the pollution that results.
