Embodiment 1

[0034] The whole bamboo unfolding process specifically comprises the following steps:

[0035] Step 1, the whole bamboo is divided into a plurality of bamboo tubes, and the bamboo tubes are cut into bamboo slices with a curved section;

[0036] The number of divided bamboo tubes varies according to the length of the whole bamboo. The length of each bamboo tube is 30-100cm, the diameter of the divided bamboo tube is 50-180mm, and the number of bamboo slices cut into equal parts by each bamboo tube is 3-6 pieces;

[0037] Step 2. The bamboo slices are heated and softened under pressure, and the softened bamboo slices are unfolded by changing the arc to determine the thickness. During the unfolding process, the bamboo green and bamboo yellow are planed;

[0038] Softening conditions under pressure and heating: pressure 1MPa, temperature 160°C, time 5min;

[0039] The expansion of variable arc and fixed thickness is as follows: according to the different radians of the material, ...

Abstract

The invention discloses an all-bamboo unfolding process, and belongs to the technical field of bamboo processing. The process comprises the following steps of: segmenting and sectioning all-bamboo into bamboo chips with radians; after being pressurized, heated and softened, unfolding the bamboo chips in a variable-arc and fixed-thickness mode, and planing off bamboo green and tabasheer; then, conducting double-face protection gradual flattening under the heat preservation condition till the bamboo chips are completely flattened, to obtain bamboo boards; and performing multi-layer ballasting shaping and compensation ballasting shaping drying on the cooled the bamboo board until the moisture content is 6-10% after being subjected to cooling treatment, and finally obtaining a bamboo board finished product after fixed-width trimming. According to the all-bamboo unfolding technology, unfolding treatment can be conducted on different sections of bamboo tubes, the effect that all-bamboo is unfolded through the same technology is achieved, it is not needed to configure multiple production technologies and corresponding production line in the unfolding process, the problem of cracking does not occur in the machining process, and the obtained bamboo board finished product is smooth and flat in surface and does not rebound.

Description

technical field [0001] The invention belongs to the technical field of bamboo processing, and in particular relates to a whole bamboo unfolding process. Background technique [0002] Bamboo can grow in 2 to 3 years, while wood generally takes at least 25 years; with the help of fiber tissue, the longitudinal tensile strength of bamboo is 5 to 6 times that of medium carbon steel; the energy consumption ratio of bamboo and concrete for buildings with the same area The energy consumption of bamboo is only 1 / 50 of that of steel in the same construction process. Due to these excellent characteristics of bamboo, it has become an important wood substitute raw material in many industries. The implementation of "replacing wood with bamboo" in some industries can effectively alleviate the contradiction between the supply and demand of wood in my country, and can also alleviate problems such as carbon emissions and the ecological environment. [0003] Cylindrical bamboo needs to be s...
