Production technology for extra-width printing nickel screen and electrical nickel-plating bath

Abstract

The invention discloses production technology for an extra-width printing nickel screen, which comprises the following steps: I, preparing molds: (1) customizing a base mold; (2) electroplating a copper coating on the base mold; (3) rolling lattice points on the external layer of the base mold; and (4) electroplating a nickel coating on the base mold to produce a screen mold; and II, preparing the nickel screen by using the prepared molds: (1) carrying out primary nickel plating to prepare a single screen; (2) removing the screen; and (3) carrying out secondary nickel plating on the single screen. The electrical nickel-plating bath adopted by the production technology comprises a plating bath body, wherein a cathode tube and a titanium basket having a plurality of baskets are arranged in the plating bath body; more than one filter pumps are arranged outside the plating bath body; a water inlet and a water outlet of the filter pump are respectively connected with the plating bath body;a carbon brake is fixedly arranged below the top of the cathode tube; the bottom of the carbon brake is connected with a power supply, and the top of the carbon brake is contacted with the cathode tube; and nickel cubes are put in the baskets of the titanium basket, and the number of the nickel cube is uniformly reduced from the middle of the titanium basket to the two sides of the titanium basket. The extra-width printing nickel screen prepared by the production technology and the electrical nickel-plating bath has the advantages of good uniformity of opening, even thickness and large aperture.

Description

technical field [0001] The invention relates to a production process of extra-wide printing nickel screen and electric nickel tank equipment used in the process. Background technique [0002] Most of the printed nickel screens produced by the existing printing nickel screen process are narrow-width nickel screens, with a length from 1800mm to 2800mm, and the corresponding printed cloth widths are 1700mm to 2700mm, which cannot print extra-wide textiles. If the wide-width nickel mesh is produced by ordinary technology, because the width of the nickel mesh is too large, the thickness of the nickel layer on the nickel mesh will be uneven, and the uniformity of the openings will be poor and the aperture will be small. Contents of the invention [0003] The invention provides a production process of an extra-wide printing nickel screen and an electric nickel tank equipment used in the process. The purpose is to solve the problems in the prior art. Good hole uniformity, uniform...

Problems solved by technology

[0002] Most of the printed nickel screens produced by the existing printing nickel screen process are narrow-width nickel screens, with a length from 1800mm to 2800mm, and the width of the corresponding printed cloth is 1700mm to 2700mm, which cannot be used to print extra-wide textiles.

If the wide-width nickel mesh is produced by ordinary technology, because the width of the nickel mesh is too large, the thickness of the nickel layer on the nickel mesh will be uneven, and the uniformity of the openings will be poor and the aperture will be small.
