Embodiment 1

[0036] A kind of drying test method of sweetgum wood of the present embodiment, basic test flow chart is as figure 1 Shown, its concrete detailed test drying method step is:

[0037] First, sorting preprocessing steps

[0038] Process the raw material of sweetgum wood into wood specimens with specifications of 200mm*100mm*20mm, polish the four sides of the specimens, namely the string section and the radial section, and select string-cut boards with no visible defects and a moisture content greater than 50%;

[0039] Second, hydrothermal cooking treatment steps

[0040] First, divide the selected string cutting boards into 9 groups on average, 4 pieces in each group;

[0041] Secondly, 9 groups of chord-cut boards were subjected to 36 orthogonal tests under three different time and temperature conditions; after treatment, they were taken out and dried separately, and the quality and size of each piece were measured; the factors and levels of the orthogonal tests were selecte...

Abstract

The invention provides a drying test method for sweetgum wood. The drying test method is characterized by comprising the following first step of separation and pretreatment, the second step of stewing hydro-thermal treatment, the third step of determination of the dry characteristics of sweetgum wood with a 100 DEG C testing method, and the fourth step of drying treatment. By means of the drying test method, the shape and dimension stability of sweetgum wood and wood products is effectively improved, and the issues such as cracking in the treatment process of sweetgum wood are avoided. The drying quality is greatly improved, the drying rejection rate is greatly decreased, the blank related to domestic drying treatment of sweetgum wood is filled up, and various properties can reach the national standard.

Description

technical field [0001] The invention relates to a drying method capable of effectively improving the drying quality of sweetgum wood, and belongs to the technical field of wood processing. Background technique [0002] Liquidambar wood grows rapidly, with fine wood structure, high toughness, moderate hardness, strength and density. There are extremely rich resources. In the case of serious shortage of our Senli resources, liquidambar wood is a kind of high utilization value. Fast-growing broad-leaved wood. However, due to the staggered and twisted texture of sweetgum wood, it is difficult to dry. During the drying process, there are defects such as cracking, warping, and serious deformation. The interlaced texture makes machining difficult, and the tool is seriously damaged, which seriously affects the direct use of this wood. Cause a great waste of wood resources. [0003] Wood drying is currently an important means to effectively improve the shape and dimensional stabili...
