Problems solved by technology

However, with the improvement of the mesh number of the printing cylinder, the densification of the mesh, and the method of controlling the width of the ribs are severely restricted. Through the traditional manufacturing process, the opening rate of the high-mesh printing cylinder is low, which is generally not possible. More than 15%, the amount of pulp seepage is low, and the printing effect is single, and due to the fineness of the printing paste particles, the net with low opening rate, the mesh aperture is too small will cause the paste to block, which will seriously affect the printing effect

Embodiment 1

[0034] (1) First make a mold with 135 mesh, 640mm circumference X 2200mm length, press the hole pattern, and control the mold rib line within 20um;

[0035] (2) Put the above mold into a special electroplating tank that requires a certain concentration and composition of the bath solution, including 15-40 g / L nickel chloride, 290-360 g / L nickel sulfate and 40-60 g / L boric acid, The non-ferrous metal nickel is used as the anode, and the mold is used as the cathode. Through the electroplating reaction, the temperature is controlled between 65-70 degrees, the current density is controlled at 20-40A / dm2, and the plating stops after 200 ampere hours. This step is also called "one-time Plating", take off the primary plated net from the mold, and then make a single plated net, the thickness of the single net is about 20um, and the opening rate is about 34%;

Abstract

The invention relates to a manufacturing method of a printing rotary screen with high mesh number and high aperture ratio. The manufacturing method comprises the following steps: (1) first, manufacturing a 125-405-mesh mould and compressing hole patterns; (2) placing the manufactured mould in a plating bath filled with a plating liquid, and preparing a primary plating single net on the surface tendon line of the mould by using nickel as the anode and the mould as the cathode; (3) placing the single net in the plating bath filled with the plating liquid by taking nickel as the anode and the single net as the cathode, adding an additive consisting of butynediol diexthoxyl ether, propynol propoxyl ether, pyridinium propyl sulfobetaine and pyridinium hydroxy propyl sulfobetaine, and thickening the single net so as to secondarily plate; and (4) taking out the secondarily plated single net, washing and drying. The additive added controls the longitudinal and transverse growth ratios of the single net tendon line, and the 125-405-mesh printing rotary screen with high mesh number and high aperture ratio is obtained. The manufacturing method overcomes the deficiencies of high manufacturing cost, environmental pollution and the like in the prior art.

Description

technical field [0001] [0002] The invention relates to a method for manufacturing a high-mesh and high-perforation printing cylinder, which is suitable for the production of a printing cylinder with a high mesh number and a high perforation rate from 125 mesh to 405 mesh. This type of high-mesh and high-perforation printing cylinder The high-efficiency printing rotary screen is widely used in high-quality, three-dimensional, rich-layer textile printing and rotary screen printing. [0003] technical background [0004] [0005] One of the existing printing rotary screens is made of a woven flat screen by welding, with weld seams, which affects the printing effect, has a short service life, and is not suitable for high-speed printing. The other is to use non-ferrous metal nickel as raw material, using the principle of electroplating, and use the "two-step electroplating method" to make it through electroplating reaction in two steps, so it is also called printed nickel me...
