Electro-induction pressing and forming plastics edge sealing negative plate
Technical field:
The utility model relates to a kind of metallic anode plate, relates in particular to the used electro-induction pressing and forming plastics edge sealing negative plate of a kind of cupric electrolysis and zinc electrolysis process.
Background technology:
The metallic cathode plate edge sealing that domestic all the time cupric electrolysis and zinc electrolysis producer are used; Usually adopt silicon rubber bar; But owing to be used for the sticker of metal and silicon rubber bar bonding usefulness, do not have the performance of electrolyte resistance chemical property and high temperature resistant degree, so Zylox edge sealing bar is eliminated gradually; And the plastic strip that adopts the interspersed edges of boards have groove to use is done the edge sealing bar and since adopt at present to only adopting plastic strip and being connected of metal sheet the clamping force mode of connection of plastic strip groove self, plastic strip is come off easily; As long as one come off, the clamping force of groove becomes flexible with regard to losing gradually, does the time spent and will come off receiving some external force; Cause worries to electrolysis production; Need often renew, thereby increase the cost of artificial and material, also directly influence electrolysis output and quality.The back side that had employing and edges of boards bound fraction to have interspersed groove, groove in recent years abroad has the plastic edge banding of tensioner bar; The edge sealing bar of this form is more better than existing domestic plastic edge banding result of use; But price is expensive especially; And also exist in case when reusing after splitting away off, the clamping force of groove obviously reduces again, re-used with the same being not suitable for of plastic strip of tighting rod basically with not after splitting away off again for the second time.More than these problems bring great worry for cupric electrolysis and zinc electrolysis producer, make each item cost up, the edge sealing bar that often appears at negative plate in the electrolysis on the way comes off and makes directly that electrolysis output is influenced, the influenced phenomenon of electrolytic prodn quality.Current social development need adapt to production environment, guarantees the goods durability, and increase of service life increases output, improves the quality, reduces cost, environmental, goods and the technology of creating benefit more.Therefore present negative plate edge sealing structure can not satisfy need of current social development.
Summary of the invention:
The utility model exists plastic edge banding to come off easily in order to solve present negative plate edge sealing structure; The clamping force of groove comes off thereupon losing gradually, causes worries to electrolysis production, increases the cost of artificial and material; Also directly influence the technical problem of electrolysis output and quality; A kind of electro-induction pressing and forming plastics edge sealing negative plate is provided, and it comprises metallic cathode plate, current conducting rod, and the two sides edges of boards of said metallic cathode plate and the edge sealing of bottom side edges of boards partly are distributed with open-work; To have and intert the plastic strip of groove and be punctured into after through electrical induction heating on the edge sealing part that negative plate passes through electrical induction heating equally, the welding pressing and forming is as a whole.
Characteristics of the utility model and beneficial effect: adopt acrylic plastering bar and negative plate through electro-induction pressing and forming edge sealing, make the applying of acrylic plastering bar and negative plate tight, connect firmly, the time limit of service prolongation need often not keeped in repair.Solved the defective that domestic and international all the time cupric electrolysis and the used negative electrode board edge sealing strip of zinc electrolysis come off easily.Formed negative plate edge sealing has the negative plate edge sealing characteristics tight, sturdy and durable, difficult drop-off of fitting that make; Play and save material, increase the negative plate time limit of service; Reduce frequency of maintenance, improve work efficiency, reduce use cost, the effect that improves electrolytic prodn output and quality.
Description of drawings:
The structural representation of Fig. 1 the utility model
Embodiment:
Referring to Fig. 1; Electro-induction pressing and forming plastics edge sealing negative plate; It comprises metallic cathode plate 1, current conducting rod 4; The two sides edges of boards of said metallic cathode plate 1 and the edge sealing of bottom side edges of boards partly are distributed with open-work 3, will have to intert the plastic strip 2 of groove through on the edge sealing part that is punctured into negative plate after the electrical induction heating and passes through electrical induction heating equally, and the welding pressing and forming is as a whole.
The said plastic strip 2 of interspersed groove and the open-work 3 that the metallic cathode edges of boards are filled up in the pressing of metallic cathode edges of boards heat-fused portion of having forms the union lever that plastic edge bandings connect together with edges of boards in the open-work 3.
Said metallic cathode plate 1 is stainless steel cathode plate or titanium negative plate and aluminium matter negative plate.
Open-work on taking in the scope of negative plate edge sealing, evenly to bore; Adopt electric induction heating process again; The edges of boards that come heating of metal negative plate 1 are to 160-180 ℃, and the edges of boards that electrical induction heating can make the negative plate that is heated only need be heated are heated fast and reduce thermal conduction, bring the effect of economize on electricity.Acrylic plastering adopts electrical induction heating equally; Be heated to 55-65 ℃; To have and intert the plastic strip 2 of groove through on the edge sealing part that is punctured into negative plate after the electrical induction heating and passes through electrical induction heating equally; Send on the pressing machine with pressure thereupon and make it and edges of boards are fitted, the part that the bonding surface of plastic strip and negative plate dissolves owing to the high temperature that receives the negative electrode edges of boards is filled up in the open-work 3 of edges of boards under the pressure effect of pressing machine; Forming plastic strip and the union lever that the metallic cathode plate is connected, is that both welding pressing and formings are as a whole.
Edge sealing is an important composition of negative plate, plays to prevent that the whole negative plate that wraps of electrolyte is to the vital role that electrolyte can not be stripped down from negative plate.Result of use, use cost, the output of decision electrolytic prodn and the important factor of quality that processing mode is the decision negative plate selected and made up to the material that is used for edge sealing on the negative plate.
This structure is used for the metallic cathode plate and the high temperature resistant degree of edge sealing bar electrolyte resistance burn into and the insulating property that are used for the electrolytic metallic cathode plate of zinc (stainless steel cathode plate or titanium negative plate and aluminium matter negative plate) its dual-side and base of cupric electrolysis.Formed negative plate edge sealing has the characteristics tight, sturdy and durable, difficult drop-off of fitting.
