The invention discloses a method for establishing a
moisture content gradient of a shaving board. The method consists of three technological links, namely
drying in levels, respective glue mixing and respective paving. The
drying in levels is characterized in that two levels of
drying systems are established and a shaving sorting procedure is set up between the first-level drying
system and the second-level drying
system; the shavings subjected to drying in levels are respectively stored, metered and mixed with glue, and the
moisture content difference between shavings in a core layer and shavings on a
surface layer are stabilized; after the shavings are metered, the shavings are respectively paved, and the
moisture content gradient is finally established on a cross section of a blank of the shaving board. By the moisture content gradient, the moisture on the surface of the blank is quickly vaporized in the heating process, a steam
impact effect is generated, the
heat transfer speed is improved, the temperature rise speed of the core layer is improved and the aims of shortening hot-pressing time and improving hot-pressing efficiency are finally fulfilled; in addition, by establishing the moisture content gradient of the blank, the performance and the surface quality of the finished shaving board can be obviously improved, the
static bending intensity of the board is improved, the made shaving board is more smooth in surface, and the sanding loss of the shaving board is reduced.
