Embodiment Construction

[0010] The carbonized tender bamboos are all selected from moso bamboos from the same bamboo production area, with the same location and uniform moisture content. The bamboo age is 2 years. The specifications of the bamboo slices are: length 560mm, width 20mm, thickness 8mm.

[0011] The design pressure of the carbonization tank is 0.85MPa, the maximum working pressure is 0.8MPa, the pressure test pressure is 1.08MPa, and the design temperature is 230°C.

[0012] The design pressure of the electric steam generator is 0.8MPa, and the maximum working pressure is 0.75MPa.

[0013] The specific implementation steps of the carbonization treatment method of described tender bamboo are as follows:

[0014] Step 1: Put the above-mentioned young bamboo pieces into the carbonization tank, and after closing the tank door, inject saturated steam to make the pressure gradually rise to 0.25MPa; at the same time, within 30 minutes after closing the tank door, gradually raise the temperatur...

Abstract

The invention discloses a carbonizing treatment method for fresh bamboos. The method comprises the following steps of selecting fresh bamboo sheets with certain size, putting into a carbonizing tank, and carbonizing according to certain process; then, naturally cooling to the normal temperature; feeding saturated steam, gradually increasing the pressure to 0.1Mpa, raising the temperature in the tank to 130 DEG C within 10 minutes, maintaining for 5 minutes, releasing the pressure, naturally cooling the carbonizing tank to normal temperature, and taking the bamboo strips out. The method has the advantages that the treated fresh bamboo strips can completely restore to the original shape after the deformation occurs; meanwhile, the fresh bamboo sheets have better physical property, consistent inner color and outer color, clear and bright texture, and anti-corrosive and anti-moth effects.

Description

technical field [0001] The invention relates to the field of bamboo processing, in particular to a carbonization treatment method for tender bamboo. Background technique [0002] The carbonization of bamboo is to sort bamboo chips of a certain specification and put them into a carbonization tank, and then inject high-pressure saturated steam into the tank to carbonize the bamboo under high temperature, high pressure and high humidity. The pressure generally requires 0.4~0.5MPa, the temperature is 130~160℃, and the carbonization period is 3~4h. Due to the severe thermal degradation and oxidative degradation reactions, the main components of the bamboo cell wall will undergo chemical reactions, and the cellulose will change color, thereby making the color of the bamboo darker. Due to the reorganization of the water-absorbing functional groups, the bamboo chips have better physical properties and the same internal and external colors. , The texture is clear and shiny. During ...
