Decorative plywood under a timbering
depending on a kind of a facing covering and pitches applied at its
manufacturing marks: DF-1 and DF-3 the transparent
colourless and painted covering on the basis of a sulphatic paper, DF-2
and DF-4.It`s can opaque covering a paper on which the drawing usually
simulating a structure of wood is put.
A plywood covering under a
timbering of marks DF-1 and DF-2, made with use pitches, less water resistance, than plywood
of marks DF-3 and DF-4 with use pitches.
To
plywood manufacturing under a timbering apply an interline interval
from wood of a birch and, less often, other deciduous breeds. For
internal it is supposed to apply an interline interval from wood of
coniferous breeds. Decorative plywood under a timbering is applied in
quality sheathered material in building, by auto- and shipbuilding,
in furniture manufacture, other areas of mechanical engineering.
Plywood for a panel board timbering and for a car - in vagono - and the structure container make of a birch interline interval and an interline
interval of coniferous breeds.
