ABSTRACT: In order to explore the substitutability of Artemisia stem for wood materials, the radial compression and bending resistance of Artemisia stem under natural conditions and microwave irradiation were studied, and the microstructural changes of materials before and after microwave drying were tested and analyzed.
The experimental data show that the microwave drying equipment is faster. In 700 W drying equipment, the moisture content of 40 g Artemisia stem can be reduced from 55% to less than 10% after 420 seconds, while the natural drying can be completed in 2.5 hours. With the prolongation of microwave drying time, the pore structure of cell wall is destroyed, and the fibrous tissue becomes dense and thinner, which increases the porosity of stem.
