Embodiment Construction

[0014] Specific embodiments of the present invention will be further described below.

[0015] The corona-treated mesh cloth of this embodiment is made of polyester material, and the mesh is arranged on the electrode frame for corona treatment on the front and back sides. The high-frequency AC voltage range of corona treatment is 4000-6000V / m 2 , The range of corona treatment speed is 15-25m / min.

[0016] Such as figure 1 As shown, the polyester mesh 1 is wound on two side-by-side guide rollers 2 , above or below the guide rollers 2 there is an electrode rod 3 mounted on an electrode frame, and the electrode rod 3 is connected to a high-frequency generator 4 .

[0017] After corona treatment, the molecular structure of the mesh surface is rearranged to produce more polar parts, which is conducive to the attachment of foreign objects. In order for the photosensitive emulsion to adhere well to the surface of the mesh, the dyne value of the surface energy of the front and back ...

Abstract

The invention relates to mesh cloth treated by corona. The mesh cloth is arranged on an electrode rack and subjected to front-side corona treatment and reverse-side corona treatment, the high-frequency alternating-current voltage range of the corona treatment is 4000-6000V / m<2>, and the speed range of the corona treatment is 15-25m / minute. The surface energy of the front and reverse sides of the mesh cloth treated by the corona is more than 10 dyne larger than the surface energy of sensitive emulsion. The mesh cloth has the advantages that the polyester mesh cloth treated by the corona can be used for printing a touch screen and mobile phone cover plate glass and is high in printing precision and long in service life, the surface of the mesh cloth is concave-convex after the mesh cloth is treated by the corona, the sensitive emulsion absorption performance of the mesh cloth is good, a produced screen printing plate is high in precision and good in high-precision printing effect.

Description

technical field [0001] The present invention relates to mesh fabrics. Background technique [0002] Ordinary mesh cloth, when printing touch screens and mobile phone covers, due to the large difference in the adhesion of the mesh cloth to different types of photosensitive emulsions, the printing effect is not good. Contents of the invention [0003] Aiming at the above-mentioned problems existing in the existing mesh, the applicant conducted research and improvement to provide a corona-treated mesh, which uses corona treatment to increase the surface energy of the mesh and improve the adhesion of the photosensitive emulsion, thereby improving the printing effect and printing quality. The stability of the effect. [0004] In order to solve the above problems, the present invention adopts the following scheme: [0005] A corona-treated mesh cloth, the mesh is arranged on an electrode frame for front and back corona treatment, and the high-frequency AC voltage range of coro...
