Production method for flattening and slicing bamboo veneer

Abstract

The invention discloses a production method for flattening and slicing a bamboo veneer. The method is characterized in that a bamboo material is softened through high-temperature steam; after the bamboo material is softened, the bamboo is pressurized and flattened by a horizontal pressing method, and thus a complete wide flattened bamboo board can be obtained; the flattened bamboo board is processed by fine slicing and sizing, glue applying, blank combining, manufacturing of bamboo blocks, softening and slicing to obtain the sliced bamboo veneer product. According to the method, the preparation process of a bamboo unit is simplified; the utilization rate of the bamboo material is increased; the quantity of adhesives is decreased, so that the environmental protection performance of the product is improved, and the production cost is decreased; adhesive layers in the bamboo blocks are decreased, and thus the water heat can be conveniently transferred, and the bamboo block softening timeis decreased, and as a result, the production efficiency is greatly improved.

Description

Technical field [0001] The invention belongs to the field of man-made board manufacturing, and specifically relates to a production method for flattening and cutting bamboo veneers. Background technique [0002] my country has always been at the forefront of the world in bamboo processing technology and product research and development. However, most bamboo products are still labor-intensive and resource-intensive products, with low technological content and serious homogeneity. Therefore, the conservation and high-value development and utilization of bamboo resources has become an inevitable development trend. In recent years, sliced ​​thin bamboo decoration materials have been successfully developed with bamboo slices as the unit. This product not only has the unique texture of bamboo with a light color, fresh and natural, but also has properties similar to precious hard broad-leaved materials and is suitable for veneer decoration materials. The development of sliced ​​thin ba...

Problems solved by technology

There are still a series of problems in the current manufacturing method, which need to be improved: the bamboo chips required for sliced ​​thin bamboo squares are of high quality, and the utilization rate of bamboo materials is low; the preparation process of bamboo chip units is complicated, it is difficult to realize continuous production, and the production efficiency Low; there are many glued surfaces in the bamboo square manufacturing process, the amount of adhesive used is large, the manufacturing cost is high, and the environmental protection is poor; the glued surface is mostly hindered by moisture and heat conduction, which is not conducive to the humidification or softening of the bamboo square; in addition, the bamboo square lumber The adhesive layer is easily affected by environmental factors such as temperature and humidity, and thin bamboo products are prone to cracks or deformation due to environmental changes
