Abstract
A kind of once-combined hemp plate is a primary raw material with the hards, is aided with rational technological process, makes that veneer and middle layer plate are once-combined to form.This product physical and mechanical property is good, and the decorative effect with real logs is made different-thickness, can be used for industries such as building, furniture packaging, and use has a extensive future.
Description
The present invention be a kind of be primary raw material with the hards, and the once-combined wood-based plate that forms.
Existing hemp plate all is to adopt the secondary operations form, has promptly increased cost, often because of the plain plate quality of hards instability, influences the quality of hemp plate again, has also influenced the use of hemp plate simultaneously.
The present invention has utilized that the plasticity that hards had is strong, shaving shape is even, and contains characteristics such as pectin, wax, is equipped with rational technological process, makes that hemp plate is once-combined to form.
Hards through screening, is screened out dust and numb suede, and dry back is also added curing agent (not adding waterproofing agent) and is fully stirred with glue, treats auxilliary dress after evenly.
Veneer is through certain air dry, the moisture content that makes veneer is between 10%～30%, carry out the edges of boards gluing then, overlap joint forms whole change the uniform hards raw material of glue mixing, be layered on by desired thickness on whole the change veneer of not applying glue or a small amount of applying glue, again another same veneer is layered on the slab,, forms combined hemp plate through giving pressure, hot pressing.
Once-combined hemp plate is by veneer and the sandwich layer slab is once-combined forms, and has reduced equipment, has alleviated working strength of workers, has reduced production cost, utilizes useless hards simultaneously, considerable benefit.
This product physical and mechanical property is good, and the decorative effect of real logs is arranged, and can make different thickness according to different purposes, and building, furniture, packaging industry all can use, and have a extensive future.
Claims (4)
