Problems solved by technology

Chinese fir has good processing performance, corrosion resistance, insect resistance, and beautiful texture and color, but its fast-growing material is poor, its structure is loose and extremely uneven, its strength and hardness are low, it is not wear-resistant, easy to absorb moisture, and its physical and mechanical strength is low.
Therefore, when the fast-growing wood is bent, it often breaks, and the bending effect is poor.

Abstract

The invention discloses a fast growing wood bending method. The fast growing wood bending method comprises the following operation steps: (S1) primary compression: a wood to be bent is perpendicular to lines for compression; (S2) softening: the primarily compressed wood is put in softening liquid for softening; (S3) compression: the softened wood is compressed along with the lines; and (S4) bending: bending assistant is uniformly coated on the convex surface of the bent wood; and the wood is put on a wood bending machine for bending to produce a finished product. As a fast growing wood is weaker in quality, the fast growing wood is rarely bent; and the fast growing wood bending method is simple in operation steps, is safe and environment-friendly in operation process, is better in quality of the bent fast growing wood, widens the application range of the fast growing wood, and improves the use value.

Description

technical field [0001] The invention belongs to the field of wood processing, and in particular relates to a fast-growing wood bending method. Background technique [0002] Fast-growing timber species refer to tree species that grow fast, mature early, and have a short rotation period. The common ones in my country include poplar, eucalyptus, pine, and willow. Fast-growing wood is generally light in color, easy to make various coating colors, and has small deformation, easy drying, light weight, relatively good dimensional stability, small shrinkage, good sound absorption effect, good elasticity, and easy processing. But its biggest problem is that the material is loose, the porosity is large, and the density is low, so the mechanical and mechanical strength are low. For example, Chinese fir, as the main timber species unique to the south, is an evergreen tree with wide distribution and fast growth. Chinese fir has good processing performance, corrosion resistance, insect ...
