25%；
D, health：It will be put into after applying glue plate drying in warehouse or balance room, temperature is in 10-50 DEG C, health 3-5 days；
E, mat formation；According to the design specification and density of lamination square bar, plate is quantitatively weighed, by the longitudinal rift grain direction of plate, layer by layer
Parallel to stack in feeder equipment, feeder equipment pushes the raw material paved in cold press, and cover plate is covered on material.
F, molding：Cold press is by material press-in die, and progressive die two ends are beaten out neatly, and pressure head is pressed onto behind position, by alignment pin
The locking hole locking cover plate that nail is squeezed on mould, pulls out cold press by mould, is pinned mould with screw rod；
G, solidification；Solidify the long 40-60m in tunnel, four curing areas in tunnel point, 90-120 DEG C of area's temperature, two area's temperature
110-125 DEG C, three 120-130 DEG C of area's temperature, four 110-120 DEG C of area's temperature；It is slow to advance, total time 6-10h；Curing process
Using continous way charging and discharge method；
H, the demoulding：Mould is from being cooled to after 35-40 DEG C, and dismounting pin and bolt, mold are stripped；
I, tack：Sawing amount in square stock two ends is equally cut flat with into termination；
J, health：It is stacked in square stock is smooth at gravity-flow ventilation；
K, sanction point：Specification as needed is cut；
L, inspection grade, repaired and packaging：Cut rear laminated timber to test, grade and repair, grade bag is then pressed again
Load storehouse.
