Abstract
The invention discloses a method for reducing wettability of a rattan cane by modification through tin-bismuth-cadmium alloy, and relates to the technical field of rattan furniture, rattan artware andrattan product processing technologies. The method comprises the following steps: processing an air-dried rattan cane into a rattan cane with the required size, and then placing the rattan cane withthe required size in a large beaker; placing a low-melting-point tin-bismuth-cadmium alloy block on the rattan cane; placing a small beaker with a heavy object on the alloy block and placing the smallbeaker with the heavy object, the alloy block and the rattan cane into a vacuum drying box together; heating until the alloy is fused completely and meanwhile vacuumizing continuously to thoroughly discharge air in gaps in the rattan cane; and heating, vacuumizing, releasing vacuum, carrying out impregnation, vacuumizing again, and carrying out impregnation again, then taking out the modified rattan cane and cooling the modified rattan cane in a dryer. By the method, the moisture absorption rate and water absorption rate of the modified rattan cane are greatly reduced, the problem that the rattan cane goes moldy and corrodes easily and easily recovers after being shaped during processing and using of the rattan cane is solved, and therefore, the additional value of the rattan cane and related products is increased.
Description
technical field [0001] The invention relates to the technical field of rattan furniture, rattan handicrafts and rattan product processing techniques, and in particular to a method for reducing the wettability of palm rattan after alloy modification. Background technique [0002] Palm rattan is a monocotyledonous plant belonging to the palm family. It is an important, multi-purpose and renewable natural green resource in the treasure house of tropical forests. It is naturally distributed in the tropical regions and adjacent regions of the Eastern Hemisphere, and expanded to the eastern part of the Indochina Peninsula and Oceania. There are more than 600 species and 93 varieties in 13 genera in the world, including 3 genera, 42 species and 26 varieties in my country. [0003] Palm rattan, commonly known as rattan, can reach 170m in length and 3mm-200mm in diameter, mostly in milky yellow, milky white, taupe and other colors. The advantage is that it is a high-quality environme...
