This method of manufacturing particle board is very similar to the wet
process only this lacks the water to form the fibrous mat. This technology
was developed in order to eliminate the waterforming process and that is
still the motivation today since there are strict measures monitoring the
effluents of such processess.
What is typically done in this process is the chips or other material is
mixed with resins and wax and then milled. This does two things;
one is to prepare the fiber to the proper size and the other is to mix
the resnis and nay other additives with the fiber. Mats are then
formed with air or other mechanical means. It must be noted that
the fibers in these mats aren't as interlocked as the wet process.
This makes the dryprocessed materials very dependant on the strength of
the binder used.
