The invention provides an OSB (
oriented strand board) base material fine surface and inner surface
veneer composite production process which uses poplar, pine and small-
diameter wood as raw materials and comprises the following steps: S1, peeling; s2, large wood shaving; s3, chipping is conducted; s4, small wood shaving; s5,
drying; s6, screening is carried out; s7, primary
sizing; s8, paving for the first time; s9, primary
hot pressing; s10, cooling for the first time; s11, carrying out primary post-treatment; s12, carrying out primary maintenance; s13, primary sanding is conducted; s14, primary grading; s15, secondary upper and lower surface fine material
sizing; s16, gluing the OSB base material, and carrying out secondary combined pavement; s17, carrying out secondary
hot pressing; s18, cooling for the second time; and S19, secondary post-treatment is carried out. S20, carrying out secondary curing; s21, secondary sanding is carried out; and S22, carrying out secondary grading. According to the OSB base material fine surface and inner facing composite production process, the basic requirement for
processing an OSB composite board can be met, the whole surface of the board can be rapidly and fully cooled, and therefore the
cooling efficiency of the board is improved, and the overall
processing efficiency is improved.
