Embodiment 1

[0025] A drying treatment method for reducing cracking of bamboo chips, including the following steps:

[0026] (1) Raw material processing:

[0027] Remove the shoots and leaves of the bamboo, cut the bamboo into a certain length of bamboo slices according to the processing requirements, and then wash off the impurities with clean water for use;

[0028] (2) Magnetic field treatment:

[0029] Put the processed bamboo slices in step (1) into a magnetic field treatment apparatus, apply a magnetic field strength of 1T, and take it out after continuous treatment for 13 minutes;

[0030] (3) Irradiation treatment:

[0031] Put the bamboo slices treated in step (2) in a closed environment, and use 60 Co-γ rays are irradiated, and the irradiation dose is controlled to 1300 Gy. After the treatment is completed, take it out for use;

[0032] (4) Thermal insulation treatment:

[0033] Put the bamboo slices processed in step (3) under the condition of 42°C, and take out after heat preservation treat...

Abstract

The invention discloses a drying process for preventingbamboo cracking,comprising the steps of (1)atraw material processing, (2)a magnetic field treatment, (3)a irradiation treatment, (4) aheat preservation processing, (5) arepeated treatment, (6) a negative pressure drying treatment.The drying process for the prevention of bamboo cracking is well designed as greatly improves the properties of the bamboo itself which can sharply reduce the stress formed and remained during drying process.As a result,the cracking rate has been brought down by over 80%,and the dried bamboo piece is high in both crack-resistance and value.

Description

Technical field [0001] The invention belongs to the technical field of bamboo chip processing, and specifically relates to a drying treatment method for reducing bamboo chip cracking. Background technique [0002] Wicker, weaving crafts and practical products using wicker as the main raw material. Willow is one of the traditional Chinese folk handicrafts. In ancient times, people were only used as ordinary daily practical products, and it gradually emerged in the later decades of the 20th century, and gradually became a project for exporting foreign exchange in some parts of China. With the development of technology, the materials used for wicker weaving have gradually expanded from the original wicker to rattan, straw rope, wood chips, bamboo chips, etc., and the products made from them are also more diversified. Bamboo sheet is one of the commonly used wicker materials. Due to its own characteristics, it is easy to crack during processing, weaving, and use. The occurrence of ...
