The invention discloses a poplar
softening treatment method, and relates to the technical field of poplar
processing. The poplar
softening treatment method comprises the steps that pre-
softening treatment is conducted, specifically, firstly poplar is
cut to be wood chips with the thickness being 3-5 cm, then the poplar is placed into a washing bath, water is added to immerse the poplar, a
cleaning agent is stirred to be completely dissolved in the water, soaking is conducted for 3-5 min, then scrubbing with clear water is conducted for 2-3 times, the poplar is taken out and dried, placed on a tension bracket to be stretched, straightened and leveled, and the pre-treated poplar is obtained; a softening agent is prepared; softening is conducted, specifically, the pre-treated poplar is placed into a softening tank, firstly water is pumped into the softening tank, so that three-quarter of water is contained in the softening tank, then the softening agent is pumped into the softening tank, so that the
mass proportion of the softening agent and the water is 1:50,
water vapor is pumped in the softening tank so that the temperature of the interior of the softening tank can be maintained to be 30-35 DEG C, the pressure intensity can be maintained to be 5-10 MPa, and continuous soaking is conducted for 3-4 days; washing is conducted; and
drying is conducted. According to the softening and
drying technology, the poplar texture is relatively soft, the
toughness is high, certain
brittleness is achieved, and the poplar is suitable for serving as materials to make pencils.
