C. and D, cleaning the fished nickel screen with water, wherein the cleaned nickel screen is used for recovering nickel, the cleaned water is used for preparing the release agent, the release agent is returned to the step A for recycling, the release agent is discharged outwards and filtered after the release agent is recycled to be turbid, the filtered release agent is returned for continuous use, and release residues are discharged outwards.
Further, the alkali in the step A is liquid sodium hydroxide or solid sodium hydroxide.
Further, when the waste printed nickel screen is soaked by the mold release agent in the step B, the mass of the mold release agent is 20-50 times of that of the waste printed nickel screen.
Compared with the prior art, the invention has the following beneficial effects: the waste printed nickel screen is soaked by using a stripping agent under a certain temperature condition, the stripping agent is a solution with the mass concentration of 5-20% prepared by alkali and water, the film on the nickel screen can be thoroughly separated from the nickel screen under the treatment of the special method, the nickel screen is insoluble, the surface layer of the stripped nickel screen is bright, no residue and no trace are left, and the film removal rate can reach more than 99%. The release agent disclosed by the invention is simple in component, wide in source and convenient to prepare, can be prepared by water for cleaning the nickel screen after release, avoids waste of water resources, can be recycled, only removes the film attached to the surface of the nickel screen, does not dissolve metallic nickel, is low in consumption and high in economic benefit. The method has the advantages of simple process, convenient operation, no waste water, easy industrialization and low cost, can realize the high-efficiency separation of the nickel screen and the membrane, and realizes the direct treatment of the waste nickel screen.
