Preparation method of Xiangfei bamboo products

Abstract

The invention relates to the technical field of bamboo product production, and in particular to a method for preparing a Xiangfei bamboo product. The method comprises the following steps: burying Xiangfei bamboo material in a silt field for 300-500 days to fully desugar and degrease the Xiangfei bamboo material; and placing the Xiangfei bamboo material in a cool and dry place for 600-800 days to make the spotted patterns on the bamboo green surface of the Xiangfei bamboo material clearer and more rosy. Compared with a direct drying method, the method has better stability and can have the appearance quality of a century-old Xiangfei bamboo. The method further comprises breaking the treated Xiangfei bamboo material into bamboo strips and bamboo slices of specific shapes, gluing the bamboo strips together through a first plane to form a semi-finished product with two green sides and two yellow sides, thereby eliminating inward stress of the bamboo and preventing mutual inward deformation. The yellow sides of the bamboo strips on both sides are then planed and glued to the second plane of the bamboo slices to form a finished product. The finished product has better stability and is not prone to deformation or bending. Furthermore, a main pole can be selected as the bamboo material, and the advantage of uniform and concentrated distribution of the bamboo green spots on the main pole is fully utilized.

Description

Technical Field

[0001] The invention relates to the technical field of bamboo product production, in particular to a preparation method of a Xiangfei bamboo product. Background Art

[0002] Xiangfei bamboo is a variant of the Bamboo family of the Poaceae subfamily, Bambusoideae. It is found in Hunan, Henan, Jiangxi, and Zhejiang provinces. Its culms are covered with brown, cloud-like purple spots. Culms range from 7 to 13 meters tall, with stems 3 to 10 cm long. The culms have purple-brown patches and spots, and the branches also have purple-brown spots. This is distinguished from the original variant by the purple-brown patches and spots on the culms and branches. It is a famous ornamental bamboo, and its culms are used for crafts and lumber.

[0003] When existing Xiangfei bamboo is made into rod-shaped bamboo products, such as brush handles and bamboo chopsticks, it is necessary to cut bamboo branches of a specific diameter. On the one hand, the number of bamboo branches of a specific diameter is limited, and the thickness is difficult to unify. On the other hand, the spots on the bamboo branches are fewer, and the spots are not as uniform and concentrated as those on the main pole. Moreover, the green Xiangfei bamboo needs to be placed for a long time before it has good stability and appearance quality. For example, century-old spotted bamboo, but the resources of century-old Xiangfei bamboo are scarce, and bamboo materials with a specific diameter and uniform spots are extremely limited. This makes it difficult to mass-produce columnar bamboo products with the appearance of century-old spotted bamboo with uniform and concentrated spots. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a preparation method of Xiangfei bamboo products, so as to solve the problem in the prior art that columnar bamboo products with the appearance of century-old spotted bamboo with evenly distributed and concentrated spots are difficult to mass-produce.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] The preparation method of Xiangfei bamboo products comprises the following steps:

[0007] Step 1: After burying the Xiangfei bamboo material in a muddy field for 300-500 days, place it in a cool and ventilated place to dry naturally. After 600-800 days, cut the bamboo into segments of appropriate lengths and break the bamboo segments into bamboo strips with a first bamboo green surface and bamboo slices with a second bamboo green surface. The bamboo strips are planed flat on three sides except the first bamboo green surface. In the bamboo strips, the side opposite to the first bamboo green surface is the first plane, and in the bamboo slices, the side opposite to the second bamboo green surface is the second plane.

[0008] Step 2: Apply glue to the first flat surfaces of the two bamboo strips and glue them together to form a semi-finished product with two sides painted green and two sides painted yellow.

[0009] Step 3: Plane the yellow bamboo surface on both sides of the semi-finished product, apply glue to the yellow bamboo surface of the bamboo piece and the yellow bamboo surface of the semi-finished product to make a Xiangfei bamboo product with green bamboo surface on all four sides.

[0010] Furthermore, in the above-mentioned method for preparing Xiangfei bamboo products, the width of the bamboo piece is equal to half of the distance from the edge of the first green surface of the bamboo strip to the first plane.

[0011] Furthermore, in the preparation method of the above-mentioned Xiangfei bamboo product, the thickness of the bamboo slices is 0.8-1.2 mm.

[0012] Furthermore, in the preparation method of the above-mentioned Xiangfei bamboo product, the Xiangfei bamboo material is selected from Xiangfei bamboo that has grown for 8 to 10 years.

[0013] Furthermore, in the preparation method of the above-mentioned Xiangfei bamboo product, the glue for coating is bovine bone glue or fish bladder glue.

[0014] Furthermore, the preparation method of the Xiangfei bamboo product further includes step 4: naturally drying the prepared Xiangfei bamboo product and then performing a carbonization treatment.

[0015] Furthermore, in the preparation method of the above-mentioned Xiangfei bamboo product, the Xiangfei bamboo material is selected from the main pole of Xiangfei bamboo.

[0016] Furthermore, in the preparation method of the above-mentioned Xiangfei bamboo product, the carbonization treatment is steam carbonization, the temperature is 220-260° C., and the heating time is 3-4 hours.

[0017] Preferably, the Xiangfei bamboo product is bamboo chopsticks.

[0018] The present invention also protects the bamboo products prepared by the preparation method of the Xiangfei bamboo products.

[0019] The beneficial effects of the present invention are:

[0020] By burying the Xiangfei bamboo in a muddy field for 300-500 days, the bamboo is fully desugared and degreased. After being placed in a cool and dry place for 600-800 days, the spotted patterns on the bamboo green surface of the Xiangfei bamboo become clearer and more rosy. Compared with the direct drying method, the bamboo has better stability and can have the appearance quality of a century-old Xiangfei bamboo.

[0021] The processed Xiangfei bamboo material is broken into bamboo strips and bamboo slices of specific shapes, and the strips are first glued together through the first plane to form a semi-finished product with two sides of bamboo green and two sides of bamboo yellow, so as to eliminate the internal stress of the bamboo and prevent mutual inward deformation. The yellow bamboo surfaces on both sides are then planed and glued to the second plane of the bamboo slices to form a finished product. Compared with bamboo products directly processed from bamboo branches, this preparation method has better stability and is not prone to deformation and bending. In addition, the bamboo material has a wider range of material selection and is not limited to branches. For example, the main pole can be selected to fully utilize the advantage of the evenly distributed and concentrated bamboo green spots on the main pole.

[0022] The Xiangfei bamboo products are dried naturally and then subjected to high-temperature carbonization treatment to strengthen the internal bonding structure and make the products more durable. The high temperature gives the carbonized surface of the bamboo products the luster and feel of Hetian jade plates and kills any remaining insect eggs inside. BRIEF DESCRIPTION OF THE DRAWINGS
