Problems solved by technology

However, the low degree of cathodic polarization leads to a limited increase in porosity, and it is prone to failure in air. At the same time, each component will deposit after long-term storage, which will affect the porosity effect.

Abstract

The invention discloses an additive for improving machining performances of a high-mesh-number cylinder printing nickel net. The additive is prepared by the following substances: 1200-1500 ml of distilled water, 120-150 g of saccharin, 130-160 g of butynediol, 120-150 ml of 80-L leveling agent, 20-30 ml of relative saturated copper sulfate solution, 20-35 ml of white oil, 5-10 g of vaseline, 5-8 gof tris, and 1-3 g of vinyl bistearamide. The additive can improve the tapping rate by 7-10& under specific conditions, has such advantages as high absorption capacity, excellent shielding property,lubricating property and stability and high cathode polarity on a cathode in secondary plating, is negatively shifted by 320 mV compared with potential, prominently delays the cathode discharge, and improves the nickel net tapping rate.

Description

technical field [0001] The invention belongs to the technical field of electrolyte additives for cylinder printing nickel screens, in particular to an additive for improving the processing performance of high-mesh cylinder printing nickel screens. Background technique [0002] At present, rotary screen printing machines are widely used in the textile and printing and dyeing industries. Rotary screen printing machines have the characteristics of low labor intensity and high machine working efficiency. Especially in the face of the floral fabrics with frequent exchange of patterns and patterns on the market, the performance requirements for rotary screen printing machines continue to increase, and the requirements for nickel rotary screens for rotary screen printing machines are also getting higher and higher. During the printing process of the nickel rotary screen, the color paste seeps out from the mesh to achieve the purpose of printing patterns. Therefore, the nickel rota...
