screen commonly used terms.
W
mesh size in the middle of the projection plane position measuring of two adjacent warp or weft wire (the distance between
See image below)
mesh size, wire diameter and pitch
.
Wire diameter d
the diameter of the wire on the wire mesh screen.
note: wire diameter may vary slightly in the weaving process.
.
Pitch p
the distance between two adjacent wire center line;
is nominally w mesh size and wire diameter d (the sum of
Pictured above)
.
The warp
woven, online all of the vertical wire.
.
Weft wire
woven, online all horizontal wire.
.

.
Opening area percentage A
in the whole screen, table surface all mesh area percentage of the total screening area.
the basic size mesh w square and basic pitch p = (
w + d)
The percentage of the ratio of the square, rounded to the integer value
.
Weave pattern
the warp and weft are intertwined with each other.
note: industrial metal braided with plain or twill weave mesh ChengFangKong (
The following figure weave pattern)
.
The stability of the metal wire woven mesh to
mesh fabric silk interwoven with soundness depends on the warp and weft wire intertexture between tension and coupling strength;
It is material tensile strength w and the influence of the ratio of d and weave pattern.
