Modified processing method for fast-growing cotton woods

Abstract

The invention relates to a modified processing method for fast-growing cotton woods, which comprises the technologies as follows: a medicine used for modified processing on the fast-growing cotton woods is prepared; the cotton woods are pre-treated; the woods in a vacuum tank are vacuumized and pressurized; the medicine is added and the woods are secondarily vacuumized; then the woods are fed into a drying room to dry; the temperature of the drying room is maintained; dry temperature balance is implemented on the woods; secondary dry temperature balance under natural conditions is implemented on the woods; and finished woods are put in storage, etc. The modified processing method for the fast-growing cotton woods has the advantages that the fast-growing cotton woods after modified processing are tested to completely reach the requirements on density, rigidity, wear resistance, stretching resistance and bending strength resistance of same woodiness growing naturally, such as briar woods, maples, basswoods, etc. Meanwhile, the modified fast-growing cotton woods also have special functions and special using effects, such as inflaming retarding, high temperature resistance, anti-deformation, no cracking, water prevention, and corrosion resistance, which are not provided by the woods growing in natural forests. The modified processing method solves the single usage and the primary processing mode that the fast-growing cotton woods can only be used for producing plywood cores, cement templates and multi-layer plates through rotatably cutting veneers; therefore, the application scope of the cotton woods is enlarged.

Description

technical field [0001] The invention relates to a method for modifying fast-growing poplar, which belongs to the technical field of wood modification. Background technique [0002] Poplar has the characteristics of fast growth, wide adaptability and easy processing, and has become a pillar industry in many regions. However, due to the inherent characteristics of soft material, rough texture and easy deformation of poplar, if it is used directly, its strength, resistance Tensile, compressive, wear resistance and texture all can't meet the needs of real estate industry, building decoration industry, furniture manufacturing industry and floor production materials. How to improve poplar wood feel, increase strength, overcome deformation and retain the characteristics of poplar wood, such as fast growth rate, beautiful color and luster, long fiber and good toughness, there is no report yet. Contents of the invention [0003] What the present invention proposes is a method for ...
