Embodiment 1
[0018] 1. Test material
[0019] (1) Preparation of palm rattan:
[0020] Select a number of white heart rattans with the rattan bark removed and air-dry them to obtain palm rattan materials; process the palm rattan materials into a number of 30mm test pieces for future use.
[0021] (2) Alloy preparation:
[0022] Tin-bismuth-cadmium alloy with a melting point of 103°C was purchased from the market.
[0023] 2. Reinforcement modification treatment of alloy and determination of weight gain rate
[0024] (1) Divide the air-dried white heart rattan specimens into two groups after being polished with sandpaper and number them respectively, and weigh the initial mass M of one group 1 , used as a modified test piece for enhanced modification (another group of materials is used as a control test piece for a control test);
[0025] (2) Put the modified test piece to be strengthened in a large beaker, put a tin-bismuth-cadmium alloy block with a melting point of 103°C on it, press...

Abstract
The invention discloses a rattan cane low-melting-point alloy enhanced modification method and relates to the technical field of processing technologies of rattan furniture, rattan handicraft and rattan products. The method comprises the following steps: air-seasoning rattan cane to be processed into the needed size, putting the rattan cane into a large beaker, placing a tin-bismuth-cadmium alloyblock onto the rattan cane, pressing a small beaker filled with weight on the large beaker, putting the beakers into a vacuum drying oven, vacuumizing to remove air in inner gaps of the rattan cane, heating to enable the tin-bismuth-cadmium alloy block to be completely melted, removing the vacuum state and restoring to an atmospheric pressure, and enabling the tin-bismuth-cadmium alloy block in amolten state to impregnate into the inner gaps of the rattan cane under the action of the internal and external pressure difference. According to the method disclosed by the invention, the density, parallel-to-grain compressive strength and the like of the rattan cane can be greatly improved, the problems in the rattan cane processing and utilizing process that a low-value rattan core is easily broken and damaged and deformation is easily recovered are solved, and the service life of the cane furniture, rattan products and rattan handicraft is prolonged.
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 enhancing and modifying palm rattan low melting point alloys. Background technique [0002] Palm rattan is a monocotyledonous plant belonging to the family of palmaceae, vine subfamily, and vine family. It is an important, multi-purpose, renewable and recyclable green non-wood resource in the treasure house of tropical forests. It is naturally distributed in the tropical regions of the eastern hemisphere. There are more than 600 species in 13 genera in the world, and 42 species in 3 genera and 26 varieties in China. [0003] Palm rattan, commonly known as rattan, can be more than 100 meters long, mostly milky white or beige, natural and fresh. Compared with wood and bamboo, it is flexible, breathable, light, low thermal conductivity, and biodegradable. High-quality environmentally friendly mat...
