Screen common terms
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.
. The number of unit length hole online n
on a given unit length line of continuous mesh number of the count.
note:. Mm length of mesh count, that is, mark & other; Mesh & throughout; And no longer use.
. 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.
the quality of the square meter weight per unit area ( Square hole) = wire diameter & times; Wire diameter & times; Mesh & divide;
square meter weight ( Lp) = ( Weft wire diameter & times; Weft wire diameter & times; The number of weft + nf diameter & times; The wire diameter & times; The number of root) ÷
. Network block
from a roll of the Internet in accordance with the provisions of side length, Angle and radius of cut off the screen.
. Net article
from processed in accordance with the provisions on the standard network roll of length and width of the width of the screen capture.
. Main defects
the effects of mesh size or larger screen surface quality of manufacturing defect.
