Fewer, the also heavy damage ecological resources of the earth, all come with some shortcomings part, in construction site, have the wood flour understood very much,
The article such as cement are discarded, the harm if not being acted upon outdoor for these article placement, to environment
It is very big.
Composite plate be usually by sandwich layer and two kinds of top layer material gluing of different nature wood composite body, commonly referred to as
For filled board, its dash board is typically all relatively thin, and sandwich layer is then thicker, and this laminar structure is actually a kind of shell structure.Table
Layer, typically conventional veneer, thin plywood, thin fiber plate, veneer or paper dalle.And the material of sandwich layer be mostly wood shavings,
Fiber, particles, bagasse, sawdust, cotton stalk particle or light foam etc..As needed, sandwich layer also can be divided from structure real
Core and hollow etc. two big class；Produced using these materials, timber utilization rate can be improved, more importantly utilize its compound effect
Really, to improve the physical and mechanical property of material.As improve dimensional stability, make density little and bending rigidity increase, and increase
The heat-insulated, fire prevention of material, the performance such as wear-resisting, corrosion-resistant；The sandwich layer of composite wooden material and structure are to its physical and mechanical property
Impact very big, if as light weight type structural material, sandwich layer may be selected the structure such as light weight or hollow wooden frame.If as sound insulation,
Heat-barrier material, sandwich layer can be selected for density less, the also not high material of intensity, such as the light porous material such as cork wood, foam plasticss.No
Pipe makees top layer and sandwich layer from what material, and they are intended to make them glued together securely with adhesive.As both are cementing
Loosely, dash board material and central layer will be peeled off and lead to destroy；Therefore the material-structure in glue and sandwich layer play critically important
Effect；But in construction or transport usually due to transportation problem or construction problem, the scratch of composite surface can be caused, make
Become the damage of composite plate, waste cost.
