Abstract
The utility model relates to ply-bamboo with raw materials of tabasheer sheets, sundry bamboo with the minor diameter, bamboo twigs and residues hot-compressed and adhered together. The ply-bamboo comprises a surface layer, a sandwich layer and a base layer. The tabasheer sheets of adjacent two layers are arranged vertically in the bamboo fiber direction. The tabasheer sheets in the same layer are interlaced and folded in the clockwise fibre direction. The number of the sandwich layer of the ply-bamboo is odd. The ply-bamboo can be made into corresponding plywood, five-ply wood, etc. The ply-bamboo is used for traffic, construction and other industries. The ply-bamboo has the advantages of high strength, wide width use and high utilization rate of bamboo. Sundry bamboo with the minor diameter, bamboo twigs and residues can be fully utilized. The finished product can not delaminated and degummed easily. The ply-bamboo which is new bamboo plywood also has the advantages of simple manufacturing process, low investment, etc.
Description
The utility model relates to a kind of bamboo fiber board, is particularly suitable for using on industries such as traffic, building.
Recently Kai Fa bamboo wood laminate, inner thin bamboo strip unidirectional array, the longitudinal strength height, transverse strength is low, and unsuitable wide format is used, and range and result of use are used in influence.
The CN87213705 patent has been announced a kind of Integral bamboo veneer, with the straight bamboo chip of thicknesser by in length and breadth or the oblique staggered glue laminated of closely arranging form, though solved the low problem of transverse strength, can wide format use, but the making of this plate need be a raw material that utilization rate of bamboo is low with big footpath bamboo, emphasize during making that bamboo chip is straight, arrange closely, technology is complicated, and equipment investment is bigger, and product is prone to the layering degumming phenomenon.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, a kind of transverse strength height is provided, but wide format is used, the utilization rate of bamboo height, even can utilize small diameter bamboo, the bamboo tip and branch, be difficult for the bamboo wood plywood laminate of layering and novelty that come unstuck, simple, the low equipment investment of technology.
The purpose of this utility model can realize by following measure: full plate can be divided into surface layer, sandwich layer, bottom, and the thin bamboo strip of adjacent two layers is along bamboo fibre direction arranged vertical, and is superimposed along the dislocation of bamboo fibre direction with the thin bamboo strip of one deck inside.
The purpose of this utility model can also be come perfect by following measure: the sandwich layer number of this plate should be odd number, and the thickness of the tabasheer thin bamboo strip of selecting for use is 1-1.7mm, and width is 5-20mm.
Accompanying drawing is the structural representation of this bamboo wood plywood laminate.
Most preferred embodiment of the present utility model is as follows: surface layer (1) and bottom (3) are 1-1.7mm with thickness, width is that the tabasheer thin bamboo strip of 5-20mm is made raw material, sandwich layer (2) also can use with the tabasheer thin bamboo strip of surface layer (1), bottom (3) same size and make raw material, is full thin bamboo strip type.Another kind is made raw material after handling through compressing tablet and physics and chemistry with small diameter bamboo or the tip of a branch, branch, be called thin bamboo strip--assorted bamboo--the thin bamboo strip type.The sandwich layer of this plate of two types can be one deck, also can be into the multilayer of odd number, and three-ply board, five-ply board, seven plywood are correspondingly arranged ...How many thickness of surface layer, sandwich layer, each layer of bottom can by superimposed the deciding of its inner yellow thin bamboo strip.
The technological process of making full thin bamboo strip type bamboo wood plywood laminate is: bamboo--blocks----drying--impregnation--drying--assembly--hot pressing--cutting edge of splitting the thin bamboo strip.
Earlier bamboo is cut into during practical operation to be put into behind the Len req burst and splits thin bamboo strip machine and be split into thick 1-1.7mm, the thin bamboo strip of wide 5-20mm, tie into wisp after choosing the air dry of tabasheer thin bamboo strip, water-soluble phenolic resin adhesive is arranged in being placed on, and (virgin rubber solid content 〉=50%, unit weight are 1.15g/cm
3) the impregnation pond in soak at room temperature 1-3 minute, going out behind the pond the thin stack pallet that is spread out in puts and sends into the typing hothouse on the layer, baking is 40-60 minute under the temperature conditions below 90 ℃, take out back assembly in the type frame, make that superimposed (it is neatly superimposed up and down promptly not to be strict with thin bamboo strip along bamboo fibre direction dislocation with the tabasheer thin bamboo strip in one deck, slightly tiltedly or in two seam folded on thin bamboo strip all can), the yellow thin bamboo strip of adjacent two layers is perpendicular, send into the hot press that gross tonnage is not less than 1250 tons then, adopt the cold cold technology that goes out of advancing, operating temperature is under 130-150 ℃ condition, and every millimeter finished product thickness of slab hot pressing 0.8-1.1 minute is finished product by the required size cutting edge again.
Making thin bamboo strip--assorted bamboo--be the thin bamboo strip type,--compressing tablet--physics and chemistry processing--spreading exhibition bundle--cleaning-drying--impregnation--drying--assembly--hot pressing--cutting edge that the yellow thin bamboo strip operating procedure of its surface layer and bottom is the same, and the technological process of its sandwich layer small diameter bamboo (comprising the tip of a branch and branch) is: small diameter bamboo.During operation small diameter bamboo is pressed into bamboo chip with the roller tablet press machine, puts in the boiling pond again, boiled 1-2 hour in caustic liquor (PH=11-12), spreading exhibition bundle in the roller rivet bucker is dry behind the water cleaning alkali liquid again.
Below step and full thin bamboo strip type facture carry out operations such as impregnation, drying, assembly and cutting edge in the same manner.
What need illustrate is that thin bamboo strip described herein and the described bamboo chip of CN87213705 patent are distinguishing, and thin bamboo strip is by splitting thin bamboo strip machine or manual being split into, and bamboo chip to be planing form, the former thickness and width are all little than the latter usually.Die with thin bamboo strip than economizing bamboo wood with bamboo chip.
This bamboo wood plywood laminate transverse strength height, but wide format use, the utilization rate of bamboo height can make full use of the small diameter bamboo and the bamboo tip, branch, and finished product is difficult for layering and comes unstuck, and technology is simple, low equipment investment.
Claims (3)
1, a kind of bamboo wood plywood laminate, sticking with glue pressure by the tabasheer thin bamboo strip or small diameter bamboo forms, can be divided into surface layer (1), sandwich layer (2) and bottom (3), the thin bamboo strip that it is characterized in that adjacent two layers is along bamboo fibre direction arranged vertical, and is superimposed along the dislocation of bamboo fibre direction with the thin bamboo strip of one deck inside.
2, bamboo wood plywood laminate as claimed in claim 1, the sandwich layer number that it is characterized in that this plate is an odd number.
