Description
Technical field
The present invention relates to a kind of processing methods of round bamboo high temperature hardening softening flattening.
Background technology
China is the country that bamboo resource is most abundant in the world, and there are about 40 to belong to 500 kinds, bamboo grove type, area and accumulation
It all occupies first place in the world, shares 4,200,000 hm of bamboo grove area2More than, wherein moso bamboo accounts for 70%.National bamboo grove area in the latest 20 years
Every year with 50,000 hm2Speed increase, the scientific research of bamboo forest cultivation, bamboo property and processing and utilization has breakthrough progress,
This for bamboo processing at various products meet economic construction and people life need provide advantageous condition.
China's economic value is higher, distribution is most wide, the maximum moso bamboo of yield, and the diameter of a cross-section of a tree trunk 1.3 meters above the ground is mostly at 7~12 centimetres or so；And
Bamboo wood also have the characteristics that wall it is thin it is hollow, taperingness is big；The outer layer Zhu Qing dense structures of bamboo wood, quality is hard, and surface is smooth, attached
There is coating of wax matter, it is poor to water and adhesive wetability；The tabasheer tissue looseness of internal layer, it is fragile, to the profit of water and adhesive
It is moist also poor；Intermediate bamboo meat, performance is green between tabasheer between bamboo, is the major part of bamboo utilization；By traditional bamboo
The problem of utilization rate of material processing method, bamboo wood is less than 30%, this also partly causes current bamboo product to hold at high price；Cause
This, it is necessary to start with from the technique of bamboo processing, develops a kind of completely new bamboo processing new process, substantially reduce current bamboo wood
Process complexity in processing solves the problems, such as that volume recovery is low in bamboo processing, and is capable of the section of General Promotion bamboo product industry
Skill content and added value of product.
Invention content
The purpose of the present invention is to provide a kind of processing methods of round bamboo high temperature hardening softening flattening.
In order to solve the above-mentioned technical problem, a kind of technical solution of the invention is a kind of round bamboo high temperature hardening softening flattening
Processing method, include the following steps：
Step 1：Fresh moso bamboo is selected, after removing the sundries that bamboo does, is cut into 0.5~2.6m circle bamboo sections, it is spare；
Step 2：The circle bamboo section blocked is respectively fed to acromere to machine, removes whole protrusion acromeres of circle bamboo section；
Step 3：The circle bamboo section for removing acromere, which is sent into, goes internal segment to machine, and removes whole internal segments of circle bamboo section；
Step 4：The circle bamboo section feeding ripsaw of internal segment will be removed, one is opened along circle bamboo segment length direction in circle bamboo section side
The swage set of perforation, it is spare；
Step 5：The circle bamboo section for completing to cut side is sent into boiling pond to impregnate 12~24 hours, the temperature control of boiling pond
Between 80~90 DEG C, circle bamboo section must be totally submerged in the hot water in soaking process；
