Description
Technical field
The present invention relates to a kind of manufacture method for the composite cylinder that do not ftracture, belong to the wooden bamboo processing skill in timber industry
Art field.
Background technology
Cool in summer and warm in winter, the beautiful texture of wooden bamboo wood, deep to be liked by people, house decoration, furniture and outdoor wood materials
All like using it, the marvellous structure that bamboo wood cylindrical structure is naturally occurring, the equal strength in this structural composites mechanics is set
Principle is counted, can be used as structural wood, such as the bamboo tower of Yunnan the Dai nationality, it is main to be built up using circle bamboo；But in use
Easily ftracture, limit the use scope as structural wood, and water, worm, rot fungi etc. is entered wherein, cause to damage by worms
Its service life defect is influenceed with rotten wait.Therefore, indehiscent composite cylinder is developed, bamboo resource sustainable use is realized
Necessary guarantee.
14 provinces, municipalities and autonomous regions of the bamboo resource integrated distribution of China on the south the Changjiang river, today, bamboo industry into
For the pillar industry in China bamboo producing region；China's bamboo grove area and bamboo wood yield are in 2011 up to 538.1 ten thousand hectares and 16.44 hundred million
Root；These provide solid, sustainable resource base for China's development bamboo processing；Outside the materials such as dry circle bamboo
Multilayer single plate is coated, indehiscent compound circular tube has just been obtained.
Fresh round bamboo short time heat treatment carbonization in temperature very high saturated vapor, then fast rapid-curing cutback at high temperature again
Dry, the temperature is on bamboo wood lignin, cellulose and hemicellulose softening point, and free from flaw after circle bamboo is dried is maintained for justifying bamboo
Optimum structure intensity originally；After charing process, the nutriment of the suitable entomogenous fungi growth in bamboo wood is decomposed, then dry
The top layer of dry circle bamboo posts several layers of veneers, and the possibility ftractureed when will circle bamboo be used greatly reduces, and its balance is aqueous
Rate is relatively low, and so its dimensional stability, corrosion resistant and mothproof ability are just improved, can as furniture material, structural lumber,
The landscape materials such as outdoor fence are used, and are improved it and are used added value.
The content of the invention
Proposed by the present invention is a kind of manufacture method for the composite cylinder that do not ftracture, its purpose be intended to manufacture one kind do not ftracture and
Surface texture cylinder attractive in appearance, makes it possess good dimensional stability, and anti-corrosion, mould proof and mothproof performance are good, more suitable for system
Make handicraft, furniture and outdoor scene.
The technical solution of the present invention：A kind of manufacture method for the composite cylinder that do not ftracture, is comprised the technical steps that：
（1）The preparation of inner core cylinder；
（2）The preparation of veneer；
（3）The winding and fastening of veneer；
（4）The solidification and post processing of multiple tube.
Advantages of the present invention：Using the circle thick bamboo tube that the too high rapid charing process of temperature saturated vapor is crossed anti-corrosion in itself,
Mothproof and mould proof characteristic, then in the treated veneer of its surface wrap, strengthens its intensity on tangential, as with intensity
High, good stability of the dimension, and anti-corrosion, mould proof and insect prevention composite cylinder, the composite cylinder can as furniture, building element,
Materials'use in terms of outdoor scene；Make it possible the large-scale production of the wooden thick bamboo tube of free from flaw, be also the strong of wooden bamboo industry
Kang Fazhan provides safeguard.
Embodiment

Urea-formaldehyde glue, glue-spread is 90~120g/m2, then its spreading is solidified on single-plate lengthening machine；By the veneer list for posting
Face epoxy resin coating, glue-spread is 50~80g/m2。
Described step（3）The winding and fastening of veneer：The two ends of inner core cylinder are fixed on rotatable device,
Then veneer band is twined from the left end of inner core cylinder to the right-hand member of inner core cylinder along inner core drum surface in 25~75 ° of spirals
Around must not have gap during winding and overlapping；After one layer of winding, veneer band is from the right-hand member of inner core cylinder to the left end edge of inner core cylinder
Inner core drum surface to continue to wind in 155~105 ° of spirals, the process for repeating the above, totally 4~10 layers of veneer, then including
The outside of core cylinder winds multilayer preservative film again, is fixed.
Described step（4）The solidification and post processing of multiple tube：Inner core cylinder after winding veneer put into temperature for 30~
Solidify 12~24h in 60 DEG C of drying room, remove preservative film after solidification, then again with sand paper by its surface polish it is clean, block,
Just obtain indehiscent composite cylinder.
Described step（1）The preparation of inner core cylinder, its inner core cylinder can also be polyethylene, polypropylene, polyvinyl chloride,

Described step（3）The winding and fastening of veneer, canoe also longitudinal texture including veneer is perpendicular to inner core
The central axis direction of cylinder, is first winding 1~3 layer, then again by the grain parallel of veneer in the central shaft of inner core cylinder thereon
Direction winds 1~5 layer；Can also veneer grain parallel in the central axis direction of cylinder, directly wind 2~10 layers in cylinder；
Then multilayer preservative film is wound in the outer layer of veneer again, be fixed.
Using dried hollow round thick bamboo tube etc. has been carbonized, veneer is posted on its external wall, the veneer can pass through spiral
Winding, can also be manufactured by the winding of multilayer concentric round type, adhesive is scribbled on veneer, after after adhesive solidification, reached vertical
The enhancing of transverse strength, reaches that composite tube does not ftracture；Justify the rapid charing process of bamboo high temperature saturated vapor and after drying, circle bamboo
Inherently there is anti-corrosion, mothproof and mould proof characteristic, top layer has veneer or the beautiful outward appearance of Bamboo veneer, treated bamboo
The marvellous structure of uniform strength design principle inherently naturally occurring, meeting in the mechanics of materials of cylinder, this structure it is outer
There is layer horizontal veneer to strengthen its tangential intensity, the good stability of the dimension of the compound circular tube；So by winding, manufacture is not opened
Split and cylinder that surface texture is attractive in appearance, its dimensional stability more preferably, and with anti-corrosion, mould proof and mothproof performance, is adapted to make work
Skill product, furniture and outdoor scene.
With reference to embodiment, the present invention will be further described：
