(8) solid wood thickness core floor surfacing
A, veneer and balance: reconciling and apply daub, and glue is that 7.5:2.5 is uniformly reconciled with flour weight ratio, then to thick core
Plate substrate crosses glue, guarantees that single spreading amount is 0.6 kilogram, by 0.5 mm of thickness solid wood veneer after gluing is uniform, according to thick core plate
Wood fibre direction or the clad can in the same direction that keeps Eucalyptus overlapping in surface layer to place or be disposed vertically with surface layer Eucalyptus, the back side is using same
The balance for carrying out corresponding power is placed in the holding of equal thickness solid wood veneer with upper layer wood skin in the same direction, completes the assembly of ground boards half-finished product；
B, cold moudling, after veneer boards half-finished product be sent into 800 tons of cold presses, 8 kilograms of pressure, carry out cold moudling in 40 minutes,
It keeps surface lining without tilting, bonds completely；
C, detection repairing, the ground boards half-finished product after cold pressing need to carry out the inspection of plate face one by one, to weight existing for the solid wood veneer of front
It is folded to carry out cuing off rejecting processing, it is homochromy to gap progress to fill up repairing, it is ensured that plate face zero defect, semi-finished product quadrangle is horizontal, no torsion
It is bent；
D, hot-forming, the semi-finished product balance after quality inspection is placed in 800 tons of multi-daylight presses, and 125 ° of machine temperature, pressure 9 is public
Jin, hot pressing are taken out after 30 minutes, and balance places natural cooling on cooling frame；
E, ground after cooling boards half-finished product is processed by shot blasting 0.5 millimeter of plate face, and sander uses 180 mesh abrasive bands, 40 hertz
Electric current, speed 25 step, and are in mirror surface standard after 0.5 millimeter of plate face is polished；
F, floor semi-finished floor is put on dedicated Sawing machine, is cut to standard specification；
G, floor is put into multiple blade saw after cutting edge, is cut according to customer demand, then clear up solid wood veneer surface → dry sanding paper
→ upper profit pool powder → Sand paper for polishing → completely scrapes first pass putty → coated abrasive working → and completely scrapes second time putty → fine sandpaper mill for polishing
Color is looked in light → brushing oil colours → brush first pass varnish → spelling, mends putty again, and fine sandpaper polishes → brush second time varnish, fine sandpaper
→ wax sealing → sorting → packaging is polished → slotted to polishing → brush third all over varnish, polishing → liquid honing matting, waxing.
