Embodiment 1

[0021] A kind of poplar wood softening treatment method is characterized in that, comprises steps:

[0022] Pre-softening treatment: first cut the poplar wood into 3cm-thick frontal wood chips, then put the poplar wood into the washing tank, add water to immerse the poplar wood, stir the cleaning agent until it is completely dissolved in water, soak it at 70°C for 3 minutes, then clean it with water Scrub twice, remove and dry, place on a tension rack to stretch, straighten and flatten to obtain pretreated poplar;

[0023] Softener preparation: prepare raw materials, 2 parts of borax, 6 parts of ammonium polyphosphate, 5 parts of glycerol, 10 parts of oxidized polyethylene wax emulsion with a solid content of 30%, 20 parts of ammonia solution with a concentration of 25%, cationic surface active 2 parts of agent, 2 parts of fatty amide, 2 parts of clay, 1 part of sodium dodecylbenzenesulfonate, 2 parts of quaternary ammonium salt, 1 part of dispersant and 20 parts of deionized ...

Embodiment 2

[0033] A kind of poplar wood softening treatment method, comprises steps:

[0034] Pre-softening treatment: first cut the poplar wood into 4cm-thick frontal wood chips, then put the poplar wood into the washing tank, add water to immerse the poplar wood, stir the cleaning agent until it is completely dissolved in water, soak it at 75°C for 4 minutes, and then clean it with water Scrub 2.5 times, take it out and dry it, place it on a tension rack to stretch, straighten and flatten to obtain pretreated poplar wood;

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of poplar wood processing, in particular to a poplar wood softening treatment method. Background technique [0002] Poplar is a plant of the genus Populus. There are more than 100 species in the genus. There are about 62 species in my country, of which 57 species are distributed in China, and about 4 species are introduced and cultivated. In addition, there are many varieties, variants and introduced strains. Poplar has a wide range of uses, not only for wood, but also mainly for processing industrial materials. Poplar has become an important additional raw material for plywood, fiberboard, paper-making matches, sanitary chopsticks and packaging. Pencil is a kind of pen used for writing and drawing and sketching. It has a history of more than 400 years. Among them, pencils for drawing and sketching are divided into many types, which are divided into three stages of development, namely Graphite, wooden pen h...
