Then secondary plus casting is carried out on the basis of semi-finished product, afterwards cleaning, drying again, forms finished product nickel screen.
5. a kind of production technology of printed nickel net as claimed in claim 1, it is characterised in that comprise the following steps：
A, core manufacture production technology：
A.1 Vehicle Processing：Outsourcing stainless-steel seamless pipe (mold base), feeding diemaking shop is entered according to design size using engine lathe
Row roughing, process can produce substantial amounts of heat, to ensure that lathe normally runs, be circulated with liquid using 1: 20 emulsion cold
But, once, per chassis, once replacing amount is 400L to bed for half a year replacing, transfers to have qualified unit safe disposal after collection；
A.2 electro-coppering pre-treatment：After mold base is machined, sand papering oil removing is then used, is first cleaned with pure water again with running water,
Electrotyping bath is sent into after the completion of cleaning carries out copper facing, and bed die can be recycled for a long time after being made；
A.3 electro-coppering：Using half into core as negative electrode, with phosphorus copper plate as anode, sulfuric acid copper content is put into for 225g/L, sulfuric acid
Content is 60g/L, during temperature is 35 DEG C of electrolyte, is passed through the direct current that current density is 5A/dm2, under electrolysis, mould
Tool surface gradually deposits 2.0mm metal platings layer；
A.4 clean：It is the starting point of mould from bed die smart car, sand papering oil removing is first used after smart car, such as surface is relatively cleaned and can use water
Cleaning one time, or thinner waterproof abrasive paper water mill is directly used, surface smoothness is improved, size is controlled, then in lathe formpiston
Oil is carefully wiped with soft material after the extruding site of its surface, hot water cleaning and descaling is used, then drying gluing insulation bakes solidifying
Gu, then 3M coated abrasive workings are used, and make 3M glue perfect in site, bridge line, diametric plane is straight and upright, and system net workshop preplating is sent into after cleaning
Nickel, thickness is 0.01mm, cleaning, drying, then is insulated, and bakes fine grinding after solidification, makes inwall fully full, and surface is smooth and bright like a mirror
Finished product die；
B, nickel screen electroforming production technology
B.1 it is passivated：By above-mentioned steps a.4 described in half be put into deactivation slot into core, passivation tank liquor selects potassium bichromate solution,
5% aqueous solution, operates under normal temperature condition, is cleaned with pure water after passivation, subsequently into electroformed nickel operation；
b.2：Electroformed nickel：Using half into core as negative electrode, with nickel plate as anode, it is put into and contains 320g/L sulfate, 30g/L chlorine
Change nickel, in the electroforming solution of 38g/L, regulation pH value is 4.0, control temperature is passed through current density for 3.5A/dm2 in 50 DEG C
Direct current, under electrolysis, die surface gradually deposits 0.04mm metal platings layer, mould is sling afterwards on tank liquor
Side stops 30 seconds, with pure water rinsing, with towel, makes nickel screen be separated with mould to form semi-finished product with fashion of extrusion, Ran Hou
Secondary plus casting is carried out on the basis of semi-finished product, afterwards cleaning, drying again, form finished product nickel screen.
