Description

Bamboo fiber bundles recombination single-plate and production method thereof

Technical field:

The present invention relates to bamboo product sheet material.

Background technology:

Chinese patent 00127973.4 " a kind of production method of bamboo veneer " and 01120942.9 " process for producing thin bamboo single sheet " disclose the production method of bamboo chip veneer; the both is after dissecing slivering bamboo or bamboo chip gummed with bamboo wood; again through the slicer slicing or be peeled into the veneer of 0.15-4MM thickness. the gummed raw material of this method all are that requirement is earlier with the mao bamboon cut growth; wide; the bamboo chip of thick unanimity just enters the gummed stage; the bamboo material of selecting for use requires height; rim charge under cutting waste simultaneously is big; effect is low; be unfavorable for large-scale production; secondly after the superimposed impregnation pressing of bamboo chip is become a useful person; glue to the infiltration of bamboo chip generally only on the surface; the bamboo chip intermediate can't infiltrate; that is to say when slicing or when being peeled into veneer; the strike-through amount of this veneer bamboo chip intermediate is little; even there is not glue; still keep the former density of bamboo wood, then this paragraph density is little, near the bamboo wood natural density.Its density unevenness is even on the whole, and averag density is little, and its averag density is slightly higher than the natural density of bamboo wood basically.

When this veneer is subjected to the expand with wet and contract with dry conditioned response under nature, ftracture easily, especially the easiest cracking of paragraph of the little cross section central body density minimum that maybe can't infiltrate of veneer Central Plains bamboo chip glue infiltration capacity, because this paragraph almost is as good as with bamboo wood nature material, expand with wet and contract with dry is big.

Secondly this veneer density unevenness is even, has another kind of effect when expand with wet and contract with dry react, and promptly its expand with wet and contract with dry reacting dose of the even place of density unevenness is also different, i.e. deflection difference, and the deflection difference can make thin plate produce bending, out-of-flatness.

Do not embody its weak point as yet as slab bamboo chip gummed, but slicing or when being peeled into veneer, slicing or rotary cutting surface might be the interface between bamboo chip and bamboo chip all or part of be glue, then this veneer is surface portion bamboo line, part gum spot, overall appearance is marred by a scar, etc., this veneer then will be eliminated, and causes waste.

Summary of the invention:

The objective of the invention is to overcome above-mentioned defective, a kind of bamboo fiber bundles recombination single-plate and production method thereof are provided.

The solution of the present invention is: veneer is to be processed into loose hand-deliver misphase company and to keep the bamboo fiber bundle gummed of original fiber alignment direction to form through the fiber fasciculation by bamboo wood, and its thickness is 0.1mm～2mm.

The veneer production method is: comprise and will wait to glue together bamboo wood laying, pressing curing process in bamboo wood drying, impregnation, stone, the forcing press, bamboo wood to be glued together is handled through the fiber fasciculation earlier before it is characterized in that drying process, sheet material after pressing is solidified is peeled into the veneer of 0.1mm～2mm through softening with slicer slicing or peeler.

The invention has the advantages that: after the pressing of bamboo fiber bundle injecting glue, the strike-through amount is many, evenly and density up to more than 1.0, therefore, slicing or be peeled into veneer after the expand with wet and contract with dry amount little, evenly, not easy to crack, make the quality of plate improve a class.Because all interfaces of bamboo fiber bundle and glue bond all are mixed uniformly, overcome bamboo chip interface portion or whole gum spot problem, the decorative appearance of veneer is optimized.This technology needn't strict subdivision etc. the geometry bamboo chip, big or small bamboo wood all can utilize, thereby operation is simple, the effect height is beneficial to large-scale production.

Description of drawings:

Accompanying drawing is a structural representation of the present invention.

The specific embodiment:

Product single board of the present invention is to be processed into loose hand-deliver misphase company and to keep the bamboo fiber bundle gummed of original fiber alignment direction to form through the fiber fasciculation by bamboo wood, and its thickness is 0.1mm～2mm.

Adhered layer, papery decorative layer are arranged on the veneer successively.Be to be glued the papery decorative layer after thin plate slicing or the rotary-cut, then can be used as ornament materials.

Production method of the present invention is:

Comprise and to wait to glue together bamboo wood laying, pressing curing process in bamboo wood drying, impregnation, the forcing press, bamboo wood to be glued together is handled through the fiber fasciculation earlier before it is characterized in that drying process, sheet material after pressing is solidified is peeled into the thin plate of 0.1mm～2mm again through softening with slicer slicing or peeler.

It is that the broken silk of bamboo chip is become the very little fibre bundle in cross section that first kind of fiber fasciculation handled.

Second kind of fiber fasciculation handled and is: bamboo chip is rolled into cross sectional shape alternate up and down and that misplace through concavo-convex wheel of channelling machine.Be about to bamboo chip and break into the blockage interval continuous cross sectional shape of arranging of dislocation up and down.

It all is the bamboo chip cross section to be cut apart be subdivided into small size that first and second kind fiber fasciculation is handled, be that the crude fibre fasciculation is handled in fact, when these materials were put into the forcing press pressing, then the thread bamboo bar of small bore was subjected to the high pressure effect to collapse the loose and staggered bamboo fiber bundle that links to each other and keep the fibrillation direction of quick-fried one-tenth.

It is that bamboo chip directly is rolled into the bamboo fiber bundle of loose staggered maintenance fibrillation direction, the disclosed technical scheme of China Patent No. that Here it is 200720008862.4 " bamboo laminated plate " through roller that the third fiber fasciculation is handled.

In addition, the fiber fasciculation enters dyeing process after handling, and enters the impregnation operation behind the dyeing process, consequently can make versicolor veneer.

The applicant's technical scheme is the similar bamboo laminated plate slicing that will handle through the fiber fasciculation before the gummed of " bamboo laminated plate " and similar this patent or is peeled into veneer in fact.The veneer quality was guaranteed after the fiber fasciculation was handled and to be made slicing or rotary-cut, and principle is to roll earlier as the bamboo chip that China Patent No. 200720008862.4 " bamboo laminated plate " discloses the applicant makes the technical scheme of mixing the synthetic bamboo laminated plate of glue laminated behind the fibre bundle.This bamboo laminated plate is because gummed the time is that gummed is not the bamboo chip gummed of prior art between the bamboo fiber bundle, because bamboo fiber bundle section ratio bamboo chip cross section is much smaller, therefore the strike-through amount is big, and strike-through is even, is the solid gummed reorganization between bamboo fiber bundle and glue homogeneous phase from its cross section.
