Abstract
A ply-bamboo used for the bottom plate of train or car is made up of bamboo through preparing thin bamboo strips, braiding curtains, drying, immersing in resin, drying, laminating by three layers, and hot pressing.
Description
The invention belongs to the bamboo cord wood in wood-based plate field.
At present, the manufacture method of domestic bamboo cord wood generally adopts thin bamboo strips used for weaving as constituting the unit, and in drying, applying glue, again after the drying, all the parallel assembly that stacks of thin bamboo strips used for weavings glues together and forms.Because thin bamboo strips used for weaving elongated flexible, at random, make its drying, applying glue and assembly operation extremely inconvenient, not only reduced labor productivity, and be difficult to guarantee the product quality requirement, particularly cause the slab thickness deviation big, make after the hot pressing thickness and the density variation of sheet material big, in order to guarantee instructions for use, must strengthen the cutting edge amount of sheet material and sheet material is carried out planing operation, thereby greatly reduce utilization rate of bamboo.
The objective of the invention is provides a kind of utilization rate of bamboo height, labor productivity height, performance is good, cost is low thin bamboo strips used for weaving curtain laminated timber for society.It mainly is used as the platform floor of train, automobile.
The present invention be with the bamboo wood be raw material with it transversal after, become tangential thin bamboo strips used for weaving with the vertical profile that wherein diameter is bigger; The less vertical profile of diameter becomes radial thin bamboo strip, then these two kinds of thin bamboo strips used for weavings are made into tangential single bamboo strip curtain and bundle bamboo strip curtain radially respectively, and with these two kinds of thin bamboo strips used for weaving curtains formation unit that is sheet material, by drying, impregnation, dry stack parallel with all thin bamboo strips used for weaving curtains is combined into the slab that the cross section slightly is turriform again, under special elastic thickness rule control, carry out the bamboo cord wood that hot-press gluing forms.
The manufacture method of thin bamboo strips used for weaving curtain laminated timber comprises the steps
1, thin bamboo strips used for weaving processing
Behind the transversal one-tenth certain-length of bamboo wood, the usefulness tangential vertical profile that wherein diameter is bigger becomes the tangential thin bamboo strips used for weaving of uniform thickness of 1.0～1.5mm, and its surface does not allow surf green and tabasheer; Diameter less reject surf green and joint every after, radially vertical profile becomes the uniform thickness radial thin bamboo strip of 2～5mm.
2, thin bamboo strips used for weaving curtain processing
2.1 the processing of tangential single bamboo strip curtain: with the tangential thin bamboo strips used for weaving of uniform thickness, be woven into the thin bamboo strips used for weaving single flat with union twist yarn and crouch, and the single bamboo strip curtain that is parallel to each other.The width of single bamboo strip curtain is the width of burr plate.
2.2 the radially processing of bundle bamboo strip curtain: with the radial thin bamboo strip of uniform thickness, be a thin bamboo strip bundle, each thin bamboo strip bundle be woven into the bundle bamboo strip curtain that is parallel to each other with union twist yarn with several thin bamboo strips used for weavings.The width of bundle bamboo strip curtain is divided into two kinds, and a kind of is the wide bundle bamboo strip curtain that equates with the width of burr plate, and another kind is to lack 2～6cm than burr plate width, is called narrow bundle bamboo strip curtain.
3, the drying of thin bamboo strips used for weaving curtain
In dry kiln, respectively single bamboo strip curtain and bundle bamboo strip curtain are carried out drying, making its moisture content is 8～14%.
4, thin bamboo strips used for weaving curtain impregnation
The thin bamboo strips used for weaving curtain is rolled into rouleau, the impregnation frame of packing into, put the impregnation frame into the glue groove by thin bamboo strips used for weaving along machine direction again, concentration be housed be 18～26% water-soluble phenolic resin adhesive in the glue groove, require thin bamboo strips used for weaving curtain surface all evenly to flood glue, then the glue frame is hung out the glue groove, and thin bamboo strips used for weaving curtain volume is placed in vertical state, remove unnecessary glue so that drip.
5, the drying of impregnation thin bamboo strips used for weaving curtain
The dry kiln of respectively single bamboo strip curtain and bundle bamboo strip curtain being packed into is to carry out drying under 60～80 ℃ of conditions in temperature, makes its moisture content 12～16%.
6, assembly
6.1 special elastic thickness rule are respectively placed in the vertical both sides on the stainless steel backing plate, respectively place a jig at elastic thickness rule two ends, and the elastic thickness rule outside is close to the jig inboard.
6.2 special elastic thickness rule are relative up and down by two, but width and highly variant metal groove are formed.The height of low groove is the thickness of sheet material, and two row's spring eyes are arranged on the steel bar at low groove middle part, and linking by two row's springs and upper groove forms an integral body, upper groove can be deep in the low groove when being under pressure, after pressure relief, under the effect of spring, upper groove can reset.The length of elastic thickness rule is slightly larger than the length of slab, and the cross-sectional configuration of elastic thickness rule is seen accompanying drawing 1.
6.3 the volume of timber (long * wide * thick) and density according to the burr plate, calculate the quality of the required thin bamboo strips used for weaving curtain of slab, then by 2～6 single bamboo strip curtains of result of calculation weighing, 1～3 wide bundle bamboo strip curtain and many narrow bundle bamboo strip curtains, its insufficient section, with the non-specification thin bamboo strips used for weaving that is unsuitable for knitting the thin bamboo strips used for weaving curtain (being called for short the thin bamboo strip that looses), replenished afterwards in the impregnation drying.
6.4 the three-decker that slab is arranged in parallel for the thin bamboo strips used for weaving curtain is made up of the bottom of broad and narrower sandwich layer and top layer.The horizontal end face of slab slightly is turriform.Slab structure, shape and see accompanying drawing 2 with the position relation of elastic thickness rule, jig.
During assembly,, parallelly stack 1～3 tangential single bamboo strip curtain, parallel again stack 1～3 wide bundle bamboo strip curtain thereon, form the bottom (underlayer thickness should less than production board thickness) of slab earlier in the inboard of two finger gauges.Then on the length direction of slab bottom, the dried union twist yarn of some impregnations of horizontal equidistant placement, the parallel thereon whole narrow bundle bamboo strip curtains and the diffusing thin bamboo strip of stacking, and its encircling is in aggregates with union twist yarn formed the sandwich layer of slab.Parallelly on sandwich layer at last stack 1～3 tangential single bamboo strip curtain as the slab top layer.
7, hot pressing
Hot pressing temperature: 120～140 ℃; Unit pressure: 40～60Mpa; Hot pressing time: 2～3min/mm
8, burr plate processing
8.1 use the cutting edge circular sawing machine, vertically saw both sides 1～3cm lath of unhairing side plate earlier, carry out horizontal cutting edge by production board length again.
8.2 use specification requirement according to sheet material, vertically saw cuts open into lath earlier, vertically mills out the required tongue-and-groove of splicing again.
Description of drawings
Accompanying drawing 2 is slab cross-sectional configuration, shape and concerns schematic diagram with the position of elastic thickness rule, jig.
1 is the metal low groove among the figure; 2 is the square steel bar that connects with low groove, processes two row's circular holes thereon; 3 is the metal upper groove; 4 is spring, and the top and the upper groove of band central spindle of the spring connect, and the spring bottom places in the circular hole of square steel bar; 5 is the stainless steel backing plate; 6 is the metal jig; 7 is tangential single bamboo strip curtain; 8 is wide radially bundle bamboo strip curtain; 9 is impregnation blending rope; 10 is narrow radially bundle bamboo strip curtain.
