Study Notes
- Lumbermill leftovers like sawdust, wood shavings, and wood chips are used to make particle board.
- The particles are chopped into small bits between 0.2 and 5 millimeters in size and less than 0.7 millimeters thick.
- The particles are dried in giant dryers fueled by leftover dust, with the humidity level dropping to 1.5 percent.
- After drying, the particles are screened by size, with larger pieces recycled through the mill and smaller pieces used for the surface layer of the particle board.
- The particles are mixed with glue, resin, water, wax, and chemical hardeners, then pressed together, cut into master boards, sanded, and stacked for cooling before being processed further at the Furniture Factory.
