Abstract
Description
Technical Field
[0001] This invention relates to the field of bamboo processing technology, and in particular to a process for making bamboo curtains. Background Technology
[0002] Bamboo strips refer to bamboo that has been split into bamboo skins or thin strips of specific dimensions. They are the basic material for making traditional bamboo utensils. From ancient astronomical instruments to daily necessities, bamboo strips carry the wisdom of Chinese craftsmanship for thousands of years.
[0003] Bamboo processing enterprises typically process bamboo into various products such as bamboo engineered wood panels, bamboo flooring, and container flooring. The main method involves processing bamboo into basic units, including bamboo strips, bamboo filaments, and bamboo fibers, and then bonding them together to create various types of bamboo products.
[0004] Bamboo strip curtains are made by splitting bamboo into strips of a specific size, arranging and stacking the strips, weaving them into a curtain using a weaving machine, impregnating the curtain with glue, and finally hot-pressing it into shape using a hot press.
[0005] However, traditional bamboo strips still have low strength after molding. When making the boards, more layers of bamboo strips and other composite materials need to be stacked to ensure strength. This makes it difficult to control the thickness of the boards and results in higher costs for the molded boards. Summary of the Invention
[0006] (a) Technical problems to be solved To address the aforementioned problems in the prior art, this invention provides a process for manufacturing woven bamboo curtains that can improve the overall strength of the woven bamboo curtains, reduce the number of layers in the sheet material formed from the woven bamboo curtains, reduce the overall thickness of the sheet material, and lower the cost of the sheet material.
[0007] (II) Technical Solution To achieve the above objectives, the main technical solutions adopted by the present invention include: A process for manufacturing a bamboo curtain, the specific steps of which are as follows: Step 1: Harvest fresh bamboo, remove debris and roots from the bamboo trunk, and cut the bamboo into 1.2m and 2.4m sections; Step 2: Use a bamboo tube removal device to remove the outer nodes of the bamboo section; select the number of slicing blades according to the diameter of the front end of the bamboo section to make the bamboo slices as flat as possible; use a bamboo slice removal device to remove the inner nodes of the bamboo slices. Step 3: Feed the bamboo strips with the inner nodes removed into the bamboo strip splitter for radial splitting. The thickness of the bamboo strips should be between 0.3mm and 2mm. Step 4: Tie the processed bamboo strips together with woven straps and put them into a wooden steaming pot for steaming; Step 5: Place the two types of radial bamboo strips that have been carbonized into a wood drying kiln for drying. Step 6: Lay 1.2m bamboo strips in a staggered pattern on the workbench, use polyester thread as the warp, and weave the laid bamboo strips into a single-layer bamboo curtain using a bamboo curtain weaving machine. Step 7: Connect the four 2.4m bamboo strips end to end and glue them together to form a continuous bamboo strip; Step 8: Fold the continuous bamboo strips in half to form folded continuous bamboo strips, and then twist the continuous bamboo strips using a twisting device to form bamboo strip rope; Step 9: Lay multiple sections of bamboo strips in a net-like pattern on the single-layer bamboo curtain, and fix the bamboo strips with a weaving machine to form a reinforced bamboo curtain unit from the single-layer bamboo curtain. Step 10: Immerse the reinforced bamboo curtain unit briefly in the adhesive solution, and remove it after the specified time has elapsed; Step 11: Hang up the glue-impregnated reinforced bamboo curtain units to drain and dry; Step 12: Place the glued and dried reinforced bamboo curtain unit into the mold and pre-press it into a sheet-like pre-pressed material; Step 13: Stack the multi-layer pre-compressed material and place it in a hot press to cure it and form a bamboo curtain; Step 14: Trim and trim the cured bamboo strips.
[0008] Furthermore, in step 4, superheated steam carbonization is used, with a cooking temperature of 110℃-120℃ and a cooking time of 30-60 minutes.
[0009] Furthermore, the drying temperature in step 5 is 60-100℃, the drying time is 5-10 hours, and the moisture content of the bamboo strips after drying is controlled at 8-10%.
[0010] Furthermore, in step 6, the bamboo strips are laid with the bamboo sections interlaced and the ends reversed.
[0011] Furthermore, in step 6, the spacing between the warp threads is 300–600 mm.
[0012] Furthermore, in step 7, the adhesive is selected from phenolic or epoxy resins, and diluted with a solvent to adjust the concentration of the adhesive solution.
[0013] Furthermore, in step 13, during the hot pressing process, the selected hot pressing pressure is 3-5 MPa and the hot pressing temperature is 135-155℃.
[0014] (III) Beneficial Effects
[0015] The beneficial effects of this invention are as follows: In the actual production process, bamboo is split into bamboo strips, which are then arranged and shaped. Long bamboo strips are then joined together and twisted into bamboo ropes. The bamboo ropes are arranged and fixed in a grid pattern. After being impregnated with glue, they are pre-pressed into sheet-like pre-pressed material. Subsequently, multiple sheets of pre-pressed material are hot-pressed into shape. The resulting bamboo curtain has higher overall strength and significantly improved shear resistance. This allows the boards formed using bamboo curtains to reduce the number of layers, reduce the overall thickness of the boards, and lower the cost of the boards. Attached Figure Description
