Description
Technical field
The invention belongs to Material Fields, more particularly, to a kind of four layers of glued board.
Background technique
Glued board be veneer is peeled by juggle or by flitch slicing at veneer, then with adhesive it is glued made of three layers or
The board-like material of multilayer usually uses odd-level veneer, and forms the orthogonal gluing of the machine direction of adjacent layer veneer.
Glued board is one of furniture common used material, is one of big plate of wood-based plate three, also for aircraft, ship, train, vapour
The effects of vehicle, building and packing case material.One group of veneer is usually formed by the orthogonal assembly gluing of adjacent layer grain direction, usually
Its dash board and inner plating are symmetrically arranged at the two sides of central core or plate core.It is criss-cross by grain direction with the veneer after gluing
The slab being made into, is suppressed under conditions of being heated or not heated.The number of plies is generally odd number, and minority also has even number.Side in length and breadth
To physics, engineering properties difference it is smaller.Common gluing board type has three-ply board, five-ply board etc..Glued board can improve timber
Utilization rate is a main path for saving timber.
Common length and width specification is：1220 × 2440mm, and thickness specification then generally has：3,5,9,12,15,18mm etc..
Chief species have：Beech, San Cheong, willow press, poplar, Eucalyptus etc..
In order to improve the anisotropic characteristic of natural timber as far as possible, make glued board characteristic uniformly, dimensionally stable, it is general glued
Plate will abide by two basic principles in structure：First is that symmetrical；Second is that adjacent layer veneer fiber is orthogonal.Symmetry principle is just
The veneer for requiring glued board ymmetry center plane two sides, no matter wood property, veneer thickness, the number of plies, machine direction, moisture content
Deng all should be mutually symmetrical with.In same glued board, the veneer of single tree species and thickness can be used, also can be used not
With the veneer of tree species and thickness；But as the mutually symmetrical with veneer tree species in any two layers of ymmetry center plane two sides are wanted with thickness.
Surface backplate allows not to be same tree species.
Make the structure of glued board while meeting two above basic principle, its number of plies should be just odd number.So glue
Plywood is usually all made into the odd numbers numbers of plies such as three layers, five layers, seven layers.The title of each layer of glued board is：Face ply is known as dash board, inner
The veneer of layer is known as core plate；Positive dash board is panel, and the dash board at the back side is backboard；In core plate, machine direction is parallel with dash board
Be known as long core plate or middle plate.In group coelosis platen slab, panel and backboard must be faced outwardly tightly.
In order to sufficiently and reasonably utilize Development of Forest Reserves plywood production, accomplish material its use to the greatest extent, the state that China newly works out
Family's standard (declaration draft) pulls service condition according to gluing, and glued board is divided into covering with paint and (needs to cover with paint, lacquer, colour wash, etc. for surface with glued board
The products such as furniture, sewing machine table and the various electric appliance casings of clear dope), finishing with glued board (be used as building, furniture, vehicle
And ship finishing material), generally decorate gluing with glued board (be suitable for pack, pad and other aspects purposes) and veneer
Plate (is used as building, furniture, vehicle, the flawless finish material of ship etc.), and glued board type is divided into again according to bonding strength：(1)I
Class (NQF) --- weatherability, the glued board of resistance to boiling water.This kind of glued board has the performances such as durable, boiling resistance or steam treatment, can be
Outdoor application.(2) II class (Ns) --- water-proof plywoods.It is amenable to cold water or short-term Hot water immersion, but not boiling resistance.(3)
III class (Nc) --- not moisture resistance glued board.
