Titanium base nickel button kind plate
Technical field
The invention belongs to the electrolytic nickel production technical field, be specifically related to a kind of titanium base nickel button kind plate.
Background technology
Titanium base nickel button kind plate is the crucial negative plate that electrolytic process is produced the nickel button, is widely used in the wet production of metallurgical electrolysis industry.Its growth post of the titanium base nickel button kind plate that uses directly is fixed on the titanium-base at present, and its rubber insulation by binding agent attached on the titanium-base, be prone to come off, phenomenon such as bubble, layering, cause rubber insulation to combine not tight with titanium-base and growth post, electrolytic solution is easily invaded titanium-base and is produced corrosion with the gap of fixedlying connected of growth post in the use, what cause titanium-base and growth post fixedlys connected inefficacy, causes the growth post to come off, and it is useless to plant blackboard newspaper.
Summary of the invention
The technical problem that the present invention solves: a kind of titanium base nickel button kind plate is provided, by the fixedly connected mode of change growth post on titanium-base, and the adhering mode of rubber insulation, improve the reliability that titanium-base and growth post are connected, prolong the work-ing life of planting plate.
The technical solution used in the present invention: a kind of titanium base nickel button kind plate, have titanium-base, uniform through hole on the described titanium-base is fixed with conductive pole on the through hole, and the isometric both sides that extend to titanium-base of conductive pole, and the two ends of conductive pole are fixed with the growth post; The surface-coated insulation layer of described titanium-base.
Described conductive pole is fixed on the through hole by shrink-fit.
Described growth post is structure in the form of a ring, and suit also is weldingly fixed on the termination of conductive pole.
The sidewall of the surface of described titanium-base and growth post adopts the sulfuration bed process to be coated with silicone rubber insulation layer.
The thickness of described insulation layer is 1.5-2.5mm.
The present invention's advantage compared with prior art:
1, the present invention has changed the fixedly connected mode of growth post on titanium-base, has overcome the caducous defective in growth post corrosion back fully;
2, the present invention changes the adhering mode of rubber insulation, make rubber insulation combine tightr with titanium-base and growth post, electrolytic solution is difficult to invade the gap of fixedlying connected of titanium-base and growth post in the use, further improve titanium-base and the reliability that the growth post is connected, prolong the work-ing life of kind of plate.
3, the present invention adopts the sulfuration bed process to be coated with insulating layer coating, has not only reduced thickness of insulating layer, has improved work efficiency again, has reduced production cost.

Fig. 2 is a structure side view of the present invention.
Embodiment
Below in conjunction with accompanying drawing 1 a kind of embodiment of the present invention is described.
A kind of titanium base nickel button kind plate has titanium-base 1, and titanium-base 1 is provided with otic placode 4 topmost, uniform through hole 5 on the described titanium-base 1, and conductive pole 6 is fixed on the through hole 5 by shrink-fit, and the conductive pole 6 isometric both sides that extend to titanium-base 1.Growth post 2 is structure in the form of a ring, and suit also is weldingly fixed on the termination of conductive pole 6.The sidewall of the surface of described titanium-base 1 and growth post 2 adopts the sulfuration bed process to be coated with silicone rubber insulation layer 3, and the thickness of insulation layer 3 is 1.5-2.5mm.
Insulation layer 3 makes titanium-base 1 with outside isolated, the outer face of grow simultaneously post 2 and conductive pole 6 expose and conductivity good.During use, the present invention is put into electrolytic solution, and the nickel molecule is being adsorbed onto under the effect of electric current on the outer face that growth post 2 and conductive pole 6 expose, after being adsorbed onto certain thickness, just produce desired " nickel button ", can obtain nickel after " nickel button " peeled off and be fastened as product.
The above only is a better embodiment of the present invention, so all equivalences of doing according to the described structure of patent claim of the present invention, feature and principle change or modify, is included in the patent claim of the present invention.
