Embodiment 1
[0032] refer to Figure 1 to Figure 3 , this embodiment provides a polymer solid aluminum electrolytic capacitor suitable for AC circuits, which includes a first connection terminal 1 , a second connection terminal 2 , a rubber cover 3 , an aluminum shell 4 and a core package 5 . The core pack 5 is composed of a first anodized aluminum foil 50 , a second anodized aluminum foil 51 , electrolytic paper 52 and a polymer electrolyte. The upper end of the first anodized aluminum foil 50 is riveted to the first connection terminal 1 , and the upper end of the second anodized aluminum foil 51 is riveted to the second connection terminal 2 . The electrolytic paper 52 is further composed of three layers of non-woven fabrics, wherein the upper layer 52a and the lower layer 52b are respectively coated spunbonded non-woven fabrics with a thickness of about 20 μm; The polyester fibers of the viscose nonwoven fabric have an average diameter of 10 to 20 μm, and the PET fibers constituting t...
Embodiment 2
[0041] This embodiment provides a method for manufacturing a 4V1200μF13*16.5mm shell size capacitor product. The structure of the capacitor product is the same as that in Embodiment 1. The method specifically includes the following steps:
[0042] 1) Use an anodized aluminum foil with a formation voltage of 7.7V, and rivet the guide pin on the anodized aluminum foil;
[0043] (2) Take two pieces of anodized aluminum foil riveted with guide pins, with electrolytic paper in the middle, wind up into a core pack with a theoretical capacity of 1800μF, and fix it with tape;
[0044] (3) Weld the two guide pins of the core package to the iron bar, immerse them in the chemical solution so that the chemical solution just submerges the core package, apply a forming voltage of 7.7V, and perform chemical conversion repair on the two anodized aluminum foils at the same time, The processing time is 40 minutes;
[0045] (4) Put the core bag after the chemical conversion repair treatment int...
Embodiment 3
[0057] This embodiment provides a method for manufacturing a 10V2200μF16*25mm shell size capacitor product. The structure of the capacitor product is the same as that in Embodiment 1. The method specifically includes the following steps:
[0058] (1) Use an anodized aluminum foil with a formation voltage of 21V, and rivet the guide pin on the anodized aluminum foil;
[0059] (2) Take two pieces of anodized aluminum foil riveted with a guide pin, and use the electrolytic paper described in Example 1 in the middle, wind it into a core bag with a theoretical capacity of 2700 μF, and fix it with tape;
[0060] (3) Weld the two guide pins of the core package to the iron bar, immerse them in the chemical solution, make the chemical solution just submerge the core package, apply a 21V forming voltage, and perform chemical conversion repair treatment on the two anodized aluminum foils at the same time. The time is 40 minutes;
[0061] (4) Put the core bag after the chemical conversio...
