Abstract
The utility model discloses a shielding device of an electrodeposited copper foil anode plate. The shielding device comprises an anode plate (3) and is characterized in that the lowest end and middle upper part of the anode plate (3) are fixedly connected with an acid-resisting adhesive tape (2); and the acid-resisting adhesive tape (2) is externally and fixedly connected with an acid-resisting PVC (poly vinyl chloride) plate (1). Therefore, the shielding device is simple to operate, easy to remove, low in manufacturing cost and cost-saving; the uniformity deviation of copper foils is controlled within 1%; and the use time of the anode plate is prolonged by 30%-50%, and the shielding device is especially suitable for electrodeposited copper foils.
Description
Technical field:
The utility model relates to a kind of electrolytic copper foil positive plate shielding unit, the arc positive plate that particularly a kind of electrolytic copper foil is used.
Background technology:
At present, China is in the electrolytic copper foil production process, and positive plate adopts titanium to be coated with iridium more; Common has two kinds, and a kind of is whole arc titanium plate, and another kind is a strip titanium plate; In the electrolytic copper foil production process, positive plate send electricity, and the copper in the copper sulfate electrolyte is reduced; Be deposited on the cathode roller, form Copper Foil; Copper Foil deposits on cathode roller uniformly, could form the internal performance of Copper Foil quality homogeneous, because positive plate can't guarantee the homogeneity of coating in the course of processing; Cause positive plate in use for some time; Partial failure causes the deposition of copper difference to occur, influences the uniformity coefficient of Copper Foil; The strip positive plate can only be changed a slice when partial failure occurring, but the arc positive plate can only all change during replacing owing to be whole titanium plate, when the copper thickness difference is very big, will change positive plate, and production cost is high.
Summary of the invention:
The purpose of the utility model is exactly to solve the arc positive plate under the situation of partial failure, still can produce the electrolytic copper foil of good evenness, thereby prolongs the electrolytic copper foil positive plate shielding unit that the positive plate life-span reduces production costs.
The purpose of the utility model is achieved in that a kind of electrolytic copper foil positive plate shielding unit, is made up of positive plate, it is characterized in that the least significant end of described positive plate is fixedly connected acidproof adhesive tape with the middle and upper part, and acidproof adhesive tape external fixation connects acidproof PVC plate.
Described acidproof adhesive tape of the utility model and acidproof PVC plate length least significant end are 2.5% of positive plate overall size, and the middle and upper part is 5% of a positive plate overall size, and acidproof adhesive tape is the acidproof adhesive tape of the two-sided elasticity of 3M.
The utility model compared with prior art has the following advantages:
Owing to adopted the least significant end of positive plate to be fixedly connected acidproof adhesive tape with the middle and upper part, acidproof adhesive tape external fixation connects the structure formation of acidproof PVC plate, thereby:
1, be easy to be processed into different shape, simple to operate, easy to use, remove easily, cost is low, practice thrift cost;
2, simple in structure, material is easier to obtain, and shielding shape handiness is strong, and the uniformity coefficient deviation control of Copper Foil is in 1%, and positive plate prolongs 30%-50% duration of service.

1, acidproof PVC plate 2, acidproof adhesive tape 3, positive plate
Embodiment:
The least significant end of positive plate 3 is fixedly connected acidproof adhesive tape 2 with the middle and upper part; Acidproof adhesive tape 2 is the acidproof adhesive tape of the two-sided elasticity of 3M; Connect acidproof PVC plate 1 at acidproof adhesive tape 2 external fixation; Acidproof adhesive tape 2 is 2.5% of a positive plate overall size with acidproof PVC plate 1 length least significant end, and the middle and upper part is 5% of a positive plate overall size.
During use; Positive plate 3 before use; Clean, use hot blast drying then, be stained with acidproof adhesive tape 2 and acidproof PVC plate 1 respectively earlier in least significant end and middle and upper part; The effect of following end shield is solve to go up positive plate discharge that liquid process fluid challenge brings evenly, and the effect of the shielding strip that the middle and upper part is divided is that the compensation annode area is used when being used for adjusting the arc positive plate and losing efficacy; After gluing shielding strip; The electricity of just can driving to send is tested the uniformity coefficient of Copper Foil, utilizes statistical technique to calculate the change shape of shielding strip; And then the shielding of antianode plate increases and decreases; Thereby the uniformity coefficient deviation that guarantees Copper Foil, reduces production costs even positive plate exists partial failure also can prolong the duration of service of 30%-50% less than in 1%.
