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

[0024] (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;

[0025] (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

A method for manufacturing a high-mesh and high-perforation printing rotary screen, comprising the following steps: (1) firstly make a 125-405 mesh mold, and press the hole pattern; (2) put the prepared mold into a plating solution In the electroplating tank, nickel is used as the anode, and the mold is used as the cathode, and a single-plated single mesh is made on the surface of the mold; (3) the above-mentioned single mesh is placed in an electroplating tank equipped with a plating solution, and nickel is used as the anode , the single net is used as the cathode, adding additives composed of butynediol diethoxy ether, propynyl alcohol propoxy ether, propanesulfonic acid pyridinium salt, and hydroxypropanesulfonic acid pyridinium salt to thicken the single net, Carry out "secondary plating"; (4) Take out the single mesh for secondary plating, rinse and dry, and it is completed. The additives added in the present invention control the longitudinal and transverse growth ratios of single mesh ribs to obtain a printing cylinder with a high mesh number and high opening ratio between 125-405. The invention overcomes the defects of high manufacturing cost, environmental pollution and the like existing in the prior art.

Description

technical field [0001] 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. technical background [0002] 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 mesh; In the electroplating tan...
