CN2058375U - Bamboo-wood compound plate - Google Patents

Abstract

The utility model discloses a bamboo-wood compound plate which is a man-made compound plate. Bamboo splints are used as a center sandwich layer. Single plates are symmetrically stuck on the two surfaces of the center sandwich layer. The use ratio of bamboo and wood is 4: 1-8: 1. The bamboo-wood compound plate is made in one time. The glue consumption is little. Industrialization and mechanization production can be easily realized. The productive efficiency is high. The bamboo-wood compound plate utilizes short and small diameter wood or the wood of fast-growing and high-yield plantation for cutting single plates used as face veneer. Bamboos are used as core plates. The bamboo splints without eliminating green bamboos and bamboo shavings are used as pallet plates. The bamboo-wood compound plate has the advantages of smooth and beautiful surface which is the same to plywood, high strength, high rigidity and dimensional stability. The bamboo-wood compound plate can be used for producing products with consistent or inconsistent crossbar intensity. The bamboo-wood compound plate can be widely used for building and furniture industries, such as cement formwork, carriage plates, packing plates, etc.

Description

Bamboo-wood compound plate

The utility model relates to artificial composite board.

Existing bamboo-wood plyboard normally is split into wide 8～12mm to bamboo wood, and the bamboo strip of thick 1.0～1.2mm is chosen pressure by hand and is woven into the longitude and latitude seat.When splitting bamboo strip, remove the tabasheer and the exocuticle bamboo green layer part of bamboo wood inside and outside wall, can only utilize the Erhuang thin bamboo strip and the three yellow thin bamboo strips to be woven into the longitude and latitude seat, longitude and latitude seat drying, gluing, the stacking bamboo mat plywood that composes, pasting veneer again through the secondary operations surface again becomes bamboo-wood plyboard.Existing bamboo-wood plyboard, owing to will split except that surf green and tabasheer, utilization rate of bamboo is low, is that its utilization rate of example only is about 60% with cizu.Braiding bamboo mat rough surface is uneven, and during the stacking gummed of gluing, glue-spread is (400～600g/m greatly ²).The slab gluing number of plies is many, braiding place starved very easily occurs, causes defectives such as the obvious foaming of fragmentary bamboo strip, and bonding quality is poor.Because bamboo wood is harder, (2.5～4.0mpa), the hot press gross pressure that production is selected for use is big, the cost height to require to select for use higher unit pressure during stacking gummed again.In order to make braiding bamboo mat texture not be emerging in the veneer surface, want secondary operations to paste again usually.Promptly be that so also difficulty is avoided weaving the bamboo mat texture and appeared, especially appear more outstanding when plate face paint back texture, thereby restriction have the scope of application of bamboo-wood plyboard now.Owing to need secondary to paste veneer again, cause labor productivity low; Energy consumption is big; The surface is not attractive in appearance; Bonding strength is not high; The product cost height.

The purpose of this utility model is: be made into warp-wise bamboo curtain splint seat with bamboo bar blanket and the Erhuang thin bamboo strip or the three yellow thin bamboo strips, the novel bamboo-wood composite board stacking with veneer again, that gummed forms, make full use of material to reach, improve composite plate quality and aesthetic feeling, the purpose of energy savings.

The utility model is to become veneer to make dash board with not high short and small of utilization rate through rounding, produces the sheet material of large format.Do not go surf green and tabasheer vertically to be split into desired wide bamboo bar by garden week five equilibrium again through mothproof processing earlier the garden bamboo, scabble ring.Width such as bamboo bar are changeed 90 ° become uniform thickness, closely arrange successively, line up bamboo bar blanket with the rope bundle and become warp-wise curtain seat shape.Again the Erhuang thin bamboo strip or the three yellow thin bamboo strips are connected to warp-wise curtain seat with line, blanket and curtain seat drying arrangement back and the stacking gummed of panel, during stacking gummed, bamboo bar blanket is a center core layer, be close to the center core layer two sides, stacking more symmetrically curtain seat layer, the bamboo line is vertical with center core layer to surface sticker veneer again, bamboo-wood plyboard.

The utility model utilization rate of bamboo is up to not spending surf green and tabasheer more than 80%, can make full use of garden, short and small footpath wood and be former material, the timber consumption is few, bamboo wood consumes than being 4: 1～8: 1, consumption glue amount is few, the slab rubberised layer is few, easily realize industrialization, mechanization is produced, the product quality height, the blemish of no existing composite plate on the market, the bamboo-wood plyboard scope of application is wide, can effectively utilize bamboo timber resource, producing significantly panel for fast-growing, high-yield woods and small diameter grade material and created condition, is the combination of bamboo wood, and wood substituted by bamboo provides new method.This utility model can be widely used in building industry, upholstery such as cement formwork, truck board, clad plate etc.

1 bamboo wood, 2 bamboo bar blankets, 3 face crossings, 4 warp-wise curtain seats, 5 longitude and latitude seats, 6 rift grain veneers.

With footpath level 200mm, the juggle of long 1000mm is peeled into the face crossing of thick 1.5mm～2.5mm or with more than the footpath level 260mm, the juggle of long 1980mm is peeled into the rift grain veneer of thick 1.5mm～2.5 mm, drying arrangement is processed into veneer and is made dash board, also available other sheet material and plastic veneer are made dash board, the garden bamboo is split into bamboo strip, is made into radially curtain formula bamboo mat with the Erhuang thin bamboo strip or the three yellow thin bamboo strips and makes inner plating fully; Earlier bamboo wood is sawn into Len req, through mothproof processing, press sheet material center core layer required thickness a (Fig. 2) as width a (Fig. 1), bamboo wood is pressed garden week five equilibrium, vertically be split into wide bamboo bar, the bamboo bar is through scabbling knot, dry, with bamboo bar width a as center core layer thickness a, bundle well-thought-out plan bar blanket (Fig. 2) difference reason is standby, and as center core layer, center core layer is clipped between the yellow thin bamboo strip warp-wise curtain seat of symmetry with bamboo bar blanket, texture is vertical each other, panel, yellow thin bamboo strip warp-wise curtain seat bamboo bar blanket warp-wise curtain seat repeatedly glues together well-thought-out plan art composite plate layer by layer.

Claims (2)

1, artificial composite plank, panel and central layer have wherein been comprised, it is characterized in that: make skin panel with the board-like veneer of sheet, with bamboo bar blanket and warp-wise curtain formula seat and (or) the stacking gummed of longitude and latitude seat and make central layer, the stacking again gummed of panel and central layer forms bamboo-wood composite board.

2, by the described artificial composite plank of claim 1, it is characterized in that: when bamboo bar blanket and warp-wise curtain formula seat were stacking, texture was vertical each other.
