United States13.2.3.1 Discussion“Bolting Grade” designations are often misused; and should not be specified without a wire diameter, as the desi

16、gnations havebecome non-standard.3.2.4 firmness, na subjective term referring to the planar rigidity of wire cloth (as a roll good, not mounted in a frame).3.2.4.1 DiscussionFirmness is established by the tensile strength of the material, the relationship of the mesh to wire diameters, the type of w

17、eave,and amount of crimp in the wires. The absence of firmness in wire cloth is termed sleaziness.3.2.5 market grade wire cloth, nwire cloth meeting a group of specifications that are typical for use in the general industrialmarket, manufactured based on using a different wire diameter for each of t

18、he common mesh designations.3.2.5.1 Discussion“Market Grade” designations are often misused; and should not be specified without a wire diameter, as the designations havebecome non-standard.3.2.6 mesh, nthe number of wires or openings per linear inch (25.4 mm), counted from the center of any wire to

20、the common mesh designations.3.2.7.1 Discussion“Mill Grade” designations are often misused; and should not be specified without a wire diameter, as the designations have becomenon-standard.3.2.8 percent open area, nthe ratio of the area of the openings to the total area expressed as a percentage, th

(1)where:OA = the percent open area,Mw = the mesh warp,Ms = the mesh shute,Dw = the diameter warp wire, andDs = the diameter shute wire.3.2.9 rectangular (off-count) mesh, neither precrimp or double crimp wire cloth having a differ

22、ent number of wires in the warpand shute, producing rectangular openings; the diameter of the warp and shute wires may be the same or different.3.2.10 screen, n(1) a surface provided with apertures of uniform size and shape; (2) another term used interchangeably forwoven wire cloth; and (3) a machin

23、e provided with one or more screen surfaces.3.2.11 selvage, nthe edge or border of wire cloth finished off so as to prevent unraveling; examples of finished edges includelooped selvage (see Fig. 1), folded selvage (see Fig. 2), cut and tucked (see Fig. 3), welded, plastic bonded, and bent-back picke

26、s or the metric equivalent (see 4.2 for the normal range of space cloth specifications).3.2.16 square mesh, nwire cloth having the same number of wires in both the warp and shute.E2016 152FIG. 1 Looped EdgeE2016 1533.2.17 Types of Crimps:3.2.17.1 crimp, nthe corrugation in the warp or shute wire, or

27、 both.3.2.17.2 DiscussionThe crimp in the wires is formed either during the weaving process, or with a crimping machine prior to weaving. If formed duringthe weaving process, the tension existing between the warp and shute wires fundamentally determines the respective amount ordepth of crimp, which

28、locks the wires in place and in part establishes the firmness of the wire cloth.3.2.17.3 double crimp wire cloth, nwire cloth woven with approximately equal corrugations in both the warp and shute wiresto lock the wires in position (see Fig. 5).3.2.17.4 flat top wire cloth, nwire cloth with deep cri

32、 cloth in which the direction of a twilled weave is reversed at regular intervals to producea striped or herringbone effect.3.2.18.2 plain, nwire cloth in which the warp wires and shute wires pass over one and under one wire in both directions (seeFig. 9).3.2.18.3 twill, nwire cloth in which the war

33、p wires and shute wires pass over two and under two wires in both directions (seeFig. 10).3.2.19 warp wires, nthe wires running the long way of the cloth as woven.3.2.20 weight per unit area, nthe weight per square foot for wire cloth can be approximated (without consideration for crimp)by the follo

38、opening in the direction of interest can be calculated by subtracting the nominal wire diameter fromthe reciprocal of the mesh in that direction as follows:Opn51/M!2D (3)where:Opn = the width opening (in decimal parts of an inch),M = the mesh, andD = the diameter wire (in decimal parts of an inch).T
