Description

Tungsten steel wire mesh

Technical Field

The utility model relates to the technical field of silk screens, in particular to a tungsten steel silk screen.

Background

Printing screen, also known as hole or mimeograph (Stencil), is a printing method in which ink is applied to a fine-meshed net cloth, so that the ink passes through the fine holes to be printed on the printed article, and the parts which do not need to be printed are protected by manually or mechanically coating and developing a polymer layer on the net cloth. Printing screen technology is now widely used in the solar field, for example, pattern printing of Finger electrodes in solar cells.

The mesh cloth is formed by interweaving metal wires of warps and wefts (1 is the warps and 2 is the wefts as shown in fig. 4), and cross joints (knots) are generated at the intersections of the warps and the wefts.

The interweaving nodes are larger, so that certain blocking is caused, the interweaving mode causes complicated production, and the production efficiency is reduced.

Disclosure of Invention

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a tungsten steel silk screen, includes warp and weft, warp and weft form network structure, and warp is located the weft top, bayonet (a) have been seted up with the position that weft corresponds on the warp, bayonet (b) have been seted up with the position that warp corresponds on the weft, bayonet (b) and bayonet (a) block.

Preferably, the warp and the weft are made of tungsten steel.

Preferably, a polymer layer is arranged below the weft yarns.

Preferably, the warp and weft have diameters of 5-25 microns.

Compared with the prior art, the utility model has the beneficial effects that:

1. in the utility model, the warp and the weft form a reticular structure, and the warp 100 is positioned above the weft, namely, the warp and the weft are not in a staggered weaving structure, so that the production difficulty is reduced, and the production efficiency is improved;

2. according to the utility model, the bayonet a is arranged at the position corresponding to the weft on the warp, the bayonet b is arranged at the position corresponding to the warp on the weft, the bayonet b is clamped with the bayonet a, namely, the warp is of a single-layer structure, the weft is of another single-layer structure, after the bayonet b on the warp and the bayonet a are clamped with each other, the warp and the weft are partially overlapped, and the positions of the warp and the weft are locked, so that the size of a node can be reduced, and blocking is reduced.
