The specific embodiment
Below in conjunction with embodiment the utility model is described further.
Disconnected wood: buy functional and resourceful timber (being mostly Imported timber),, log is cut into the disconnected wood of corresponding specification according to the base material specification of being produced.For guaranteeing the peak use rate of timber, should confirm suitable disconnected wooden position according to length, the position of defects in log, shape, the size of log.
Boiling is softening: the disconnected wood that cuts is carried out boiling handle; Purpose is to make disconnected wood softening, in veneer cutting (sawing, slicing, rotary-cut) process, can reduce phenomenons (because timber is harder) such as timber fracture, generation burr; Also can improve the application life of cutter, improve the product volume recovery.Clear water boiling 5-10 days is adopted in boiling, and temperature 90-100 ℃, for guaranteeing good cooking effect, temperature-rise period should not be too slowly or be too fast; At first 30-50 ℃, boiling 3-8 hour, 50-70 ℃ then, boiling 3-8 hour; 70-90 ℃ again, boiling 3-8 hour, last 90-100 ℃ of boiling.
The cutting veneer: according to the production needs, the disconnected wooden cutting after the boiling (sawing, slicing, rotary-cut) is become the veneer of respective thickness.In process of production, avoid the generation of burr.
Veneer is handled: after the cutting, for preventing or reduce veneer and in the process of drying, ftracture that the wet glue band of edge sealing will be pasted in the veneer two ends; Because wooden wetting, can have two kinds of methods this moment, that is: not wet earlier water; See whether can cement,, paste again behind the water that then don't fail to wet as sticking not firm.
Veneer drying: for ease of subsequent production; To carry out dried to moistening veneer,, make dried veneer moisture content reach requirement through the temperature of adjustment drier and the speed of guipure (or roller); If necessary; Will dry again several times (preferably can once just can drying put in place, with reduce move, pull cause in the process that veneer is torn, fragmentation), reach requirement until moisture content.The final moisture content of veneer is controlled at 4%-12%, generally speaking, baking temperature 110-200 ℃, speed 0.5-4m/min, length 10-22 joint.
