Abstract

The invention relates to bamboo plywood. The bamboo plywood consists of a surface layer, a core layer and a bottom layer, wherein each layer of bamboo split blocks in the core layer is cut into bamboo splits with consistent thicknesses along the radial direction by using phyllostachys pubescens or thick-wall bamboo, and the bamboo splits are paved into a whole block. The utilization ratio of bamboo is increased, the tolerance consistence of batch production is ensured, and mechanical and industrial production can be realized. Moreover, bamboo green and tabasheer are not positioned on a cementing surface, so that the mechanical strength is high.

Description

A kind of bamboo plywood

Technical field

The present invention relates to artificial bamboo plywood, particularly bamboo slights glued board.

Background technology

Popular is bamboo mat plywood in the market, and bamboo is split into thin bamboo strips used for weaving along tangential, forms sheet material through braiding, gluing or impregnation, hot-press gluing.Zhongnan Forestry Inst. improved this product afterwards, people's bond paper is added in assembly operation in bamboo mat plywood production process, above-mentioned production all uses tangential bamboo to slight, and after bamboo wood can only cut open into the bamboo chip of 10 ~ 25 mm wides, more tangentially splits the thin bamboo strip, surf green, tabasheer must be eliminated, this is just difficult to utilize irregular bamboo chip, the bamboo fibre of larger proportion and all bamboo tails can not be utilized, cause utilization rate of bamboo only to have 30% ~ 50%, to bamboo wood waste greatly, production cost is also high.

Summary of the invention

The object of this invention is to provide the bamboo plywood that a kind of thickness tolerance is consistent, fiber quality is even, mechanical strength is high, utilization rate of bamboo is high, production cost reduces.

The present invention takes following technical scheme: a kind of bamboo plywood, glued together by surface layer, sandwich layer and primer and form, surface layer and bottom can be veneer, bamboo mat, tectorial paper, sandwich layer is the iterative structure that a multi-layer bamboo slights block, it is vertically superimposed by bamboo fibre direction that the bamboo of every adjacent two layers slights sheet block, and same layer slights block composition with the bamboo that the bamboo that bamboo or heavy wall bamboo are radially cut into consistency of thickness is slightd rear tiling and becomes a monoblock.

Cut direction due to bamboo is divided equally along the radial equal thickness of bamboo, guarantee has unanimously been had to product thickness, the bamboo that radial direction cuts out is slightd, and the thickness not because of bamboo wood is influenced, no matter therefore bamboo footpath size, all do not spend surf green, tabasheer, abandon bamboo tail, utilization rate of bamboo can reach 70% ~ 90%, reduces the cost that bamboo slights processing glued board, can also realize mechanization, factorial praluction, and surf green, tabasheer not at cemented surface, so mechanical strength is high.

Detailed description of the invention

Below in conjunction with drawings and Examples, the present invention is further elaborated.

See accompanying drawing, a kind of bamboo plywood, its bottom 3, surface layer 1 are tectorial papers, and sandwich layer 2 is that a multi-layer bamboo slights the superimposed of block.Every adjacent two layers bamboo slights block, and to slight machine direction by bamboo vertically superimposed, to ensure overall mechanical strength, in sandwich layer, bamboo slights block 2 is first by bamboo or heavy wall bamboo length section material on request, after trisection cuts into naturally wide thick bamboo sheet bar open, remove interior acromere, be cut into uniform thickness along thick bamboo sheet bar radial direction and have a small amount of bamboo fibre fibre bamboo even to slight between sheet, slightd by these bamboos again and play side tiling, roll extrusion becomes bamboo and slights block 2.Sandwich layer bamboo slight adjacent bamboo in block enlarged drawing slight the surf green of sheet 4 relative with tabasheer in the middle of still retain bamboo fibre 5.

Claims

1. a bamboo plywood, glued together by surface layer (1), sandwich layer (2) and bottom (3) material and form, sandwich layer (2) is the iterative structure that a multi-layer bamboo slights block, it is arranged vertically by bamboo fibre direction that the bamboo of every adjacent two layers slights block, it is characterized in that: same layer slights block composition with the bamboo that the bamboo that bamboo wood is radially cut into consistency of thickness is slightd rear tiling and becomes a monoblock.

2. a kind of bamboo plywood according to claim 1, is characterized in that: the radial bamboo that each bamboo slights block is slightd between (4) that a small amount of bamboo fibre (5) is fine mutually to be connected.
