Process for manufacturing bamboo board with curve textures

Abstract

The invention discloses a process for manufacturing a bamboo board with curve textures; to solve the problems that the current bamboo board has the disadvantages of poor tangential tensile and anti-bending performances, easiness in cracking, and straight and dull bamboo textures resulting in influencing appearance and market price, the process disclosed by the invention comprises the steps of: arranging manufactured glue-coated bamboo pieces between moulds with curve surfaces; extruding the moulds with the curve surfaces till all bamboo pieces are bonded to form an integrated bamboo board; and quantifying and moulding the obtained integrated bamboo board to obtain the bamboo board with curve textures. The applied pressure for extruding the moulds with curve surfaces comprises main pressure of 1400-1600 tons and lateral pressure of 160-200 tons. The process for manufacturing the bamboo board with curve textures is used for manufacturing bamboo boards with curve textures on the surfaces, so that the attractive appearance of the bamboo board is improved greatly; on the basis of ensuring the balance of longitudinal and transverse internal stresses of the bamboo board, the transverse tensile of the bamboo board is strengthened and the transverse cracking of the bamboo board can be prevented, so that the bamboo board has the characteristics of better stable performance and increased market potential.

Description

technical field [0001] The invention relates to a process for making bamboo boards using bamboo as a raw material, in particular to a manufacturing process for bamboo boards with curved textures. Background technique [0002] Bamboo is a hollow fast-growing herb that grows within one year, and its fibers can reach the relevant standards for making boards in three to four years. The bamboo fiber is vertical, the fiber is compact, the texture is hard, the fiber vertical direction is tensile, bending, high strength, and excellent tensile performance; but because it has no horizontal or oblique interweaving fibers and no annual ring texture, its chord direction (commonly known as Transverse) Tensile strength is poor. [0003] The texture of the existing bamboo board made of bamboo slices is distributed in a straight line without changing the vertical direction of the bamboo fiber, so its chord tensile and bending resistance are poor and easy to crack, the texture of the bamboo ...

Problems solved by technology

The bamboo fiber is vertical, the fiber is compact, the texture is hard, the fiber vertical direction is tensile, bending, high strength, and excellent tensile performance; but because it has no horizontal or oblique interweaving fibers and no annual ring texture, its chord direction (commonly known as Transverse direction) Poor tensile strength

[0003] The texture of the existing bamboo board made of bamboo slices is distributed in a straight line without changing the vertical direction of the bamboo fiber, so its chord tensile and bending resistance are poor and easy to crack, the texture of the bamboo board is straight and monotonous, and the appearance cannot be compared with the wood Compared with rich texture, it affects the appearance and market price
