Abstract

The utility model relates to a novel metal printing net, which is composed of metal silk warps (1) and metal tram silks (2), wherein the metal silk warps (1) and the metal tram silks (2) are repeatedly crossed and woven to form a plain weave or an oblique weave printing net according to a certain rule up and down. The shape of net holes of the utility model is stable, the thickness of a silk net is uniform and accordant, and the utility model is suitable for printing fine line patterns with the requirement of high quality.

Description

Novel metal printing net

Technical field

The utility model relates to a kind of printing net, refers to that especially this type printing net adopts high-precision metal silk (for example stainless steel wire) to carry out longitude and latitude and is interwoven.The mesh and the screen thickness of structure are even, and be not yielding, and the mesh polarization is stable, and no electrostatic effect is not disturbed by light radiation.The structure of this printing net is specially adapted to the grain pattern printing that meticulous high-quality requires, and especially more is applicable to the printing of hot melt ink.

Background technology

Serigraphy is usually adopted in the printing of in the current printing industry printing quality being had relatively high expectations, and claims porous printing again, and this method is used till today always.The serigraphy of commonly using, its printing net all is to make twine by nonmetallic spun silk, nylon yarn etc.Low (the 200N/mm of braiding structure bulk strength that this class material is formed ²≤ σ≤400N/mm ²), percentage elongation height (〉=80%), fatigue strength is low, fusing point low (T≤250 ℃～256 ℃), anti-light radiation ability is low, integrates these factors and can make the configuration ability of nonmetal printing web frame low, especially the stable extreme difference of mesh location moulding, wire side is smooth to differ, service life is short, cracky, and working service repairing property is very poor, cause printing quality low, the printing cost height.

Under the situation of current production development, how to improve printing quality, reduce printing cost, improve the working service performance of printing net, be the task of top priority.

Summary of the invention

According to background technology, the purpose of this utility model is to provide a kind of operplate printing net, carrying out longitude and latitude by the high-precision metal silk is interwoven, the mesh and the screen thickness of its structure are even, not yielding, mesh dimensionally stable, intensity height, long service life, the operplate printing net of plain weave that maintainability is good and twill structure.

To achieve these goals, the utility model is achieved through the following technical solutions:

A kind of novel metal printing net, mainly by metal organizine (1), metal tram (2) is formed, wherein: along laterally with metal tram (2) one on the other (or on two two times) mode pass through metal organizine (1), interlacing longitudinally metal tram (2) is changed into (or on two times a two) mode on next and is passed through metal organizine (1), what the mode of passing through alternately of longitudinally repeating constituted the operplate printing net is fixed structure, wherein, being formed by the metal organizine (1) of promptly deciding diameter and metal tram (2) is the square mesh (4) of sizing.

Owing to adopted technique scheme, the utlity model has following advantage and effect:

1, version of the present utility model can replace traditional silk screen of commonly using fully, adopting metal wire rod is under raw material and the new construction situation that adapts with it, operplate printing net intensity is compared percentage elongation greatly with it very low, if compare with nylon with stainless steel, under the two same percentage elongation situation, the tensile strength of stainless steel material is about 8 times of nylon material when the stainless steel tension is in yield point.Therefore, the mesh precision height of operplate printing net, dimensionally stable, screen thickness uniformity, no electrostatic effect, not disturbed by light radiation, can be used for the grain pattern of printed with fine high-quality requirement, can be used for the printing of hot melt ink, be particularly useful for the photoelectron product, the thick film wiring board, instrument dial, accurate printing industry such as glass ceramics.

2, the utility model is easy to make, and working service is repaired simple and easy.

The specific embodiment

Illustrate by Figure 1A, Figure 1B, Fig. 2 A, Fig. 2 B, a kind of novel metal printing net, mainly by metal organizine 1, metal tram 2 is formed, wherein: along laterally with metal tram 2 one on the other or on two two times modes pass through metal organizine 1, interlacing longitudinally metal tram 2 change into one on next or two times two upper types pass through metal organizine 1, what the mode of passing through alternately of longitudinally repeating constituted the operplate printing net is fixed structure, wherein, being formed by the metal organizine 1 of promptly deciding diameter and metal tram 2 is the square mesh 4 of sizing.

The experiment function relation curve figure of stainless steel wire, nylon yarn, dacron thread is shown by Fig. 3.Three curves from Fig. 3 find out that the slope of curve of metal twine is higher than nonmetallic materials, illustrate that tension can reach yield value of stress to the metal twine under the both sidesization extending to.The tension of nonmetal twine and extension value almost are directly proportional and make linear growth.This characteristic can combined influence to the quality of printing net, the shape stability of mesh for example, the thickness evenness of silk screen, the possibility that optimum tension is adjusted, percent opening etc.

The percent opening of stainless steel pringting net is an important parameter of describing the mesh size.Percent opening serious offense China ink amount is big, produces unnecessary loss.Percent opening is little can not to guarantee pattern lines definition, influences printing quality.The utility model is according to the fabric characteristics, stipulated the corresponding various order numbers of stainless steel pringting net, line through etc. gauge mesh extrapolate the percent opening calculating rule:

P＝[W/(W+D)] ²×100％

P-percent opening (%) in the following formula

W-aperture (mm)

The D-line is through (mm)

Or: P=[(25.4-DM)/25.4] ²* 100%

Interior warp of M-per inch length or parallel radical in the formula

By the quantity of ink of silk screen, determined that by factors such as silk screen material, performance, specification, printing ink viscosity, stock kind, web lines warp and thickness it does not have definite index.The utility model by practice, has been concluded the parameter index of crossing the China ink amount with reference to percent opening and screen thickness:

V＝P*δ*1000

V---crosses China ink amount (cm in the formula ³/ m ²)

P---percent opening (%)

δ---silk screen average thickness (mm)

Claims

1, a kind of novel metal printing net, mainly form by metal organizine (1) and metal tram (2), it is characterized in that: along laterally with metal tram (2) one on the other (or on two two times) mode pass through metal organizine (1), interlacing longitudinally metal tram (2) is changed into (or on two times a two) mode on next and is passed through metal organizine (1), what the mode of passing through alternately of longitudinally repeating constituted the operplate printing net is fixed structure, wherein, being formed by the metal organizine (1) of promptly deciding diameter and metal tram (2) is the square mesh (4) of sizing.
