電子鋁箔工藝

電子鋁箔主要產品有 1000 和 3000 系列鋁合金. 電子鋁箔主要應用於電子元件等領域. 華威鋁電子箔市場佔有率高, 產品性能穩定, 品質優良, 以及較高的市場認可度.

電子鋁箔是高純度鋁箔, 由精煉鋁製成 (高純度鋁) 熱軋成鋁板的鋁錠, 然後進一步冷軋和退火. 電子鋁箔的具體生產流程包括: 熔煉鑄造-均熱-熱軋-預退火-冷軋-中間退火-冷軋-箔軋-縱剪-性能檢測-包裝.

電子鋁箔的分類

電子鋁箔可分為高壓陽極箔, 低壓陽極箔, 負極箔, 等等. 高壓陽極箔被腐蝕成柱孔狀, 低壓陽極箔像海綿一樣被腐蝕, 中壓段陽極箔如飛蛾般被腐蝕.

高壓陽極箔可分為兩類, 一是優質高壓箔; 另一種是普通高壓箔. 高品質高壓陽極箔的特點是“二高一薄”, 那是, 高純度, 高立方織構和薄表面氧化膜.

此類產品品質優良, 但成本高. 鋁的純度為 >99.99%, 立方紋理是 96%, 真空熱處理在10-3pa～10-5Pa條件下進行. 普通高壓陽極箔是一種經濟實用的高壓陽極箔. 鋁的純度為 >99.98%, 立方紋理是 >92%, 真空熱處理在10-1pa～10-2pa條件下進行.

電子鋁箔技術分析

電子鋁箔的生產是一個精密加工過程, 而產品的品質與原料的先進水準有著重要的關係, 控制系統, 及生產設備.

從全球角度來看, 儘管我國電子鋁箔生產發展迅速, 歐美企業先進技術仍具優勢, 尤其是高壓電子鋁箔.

Since electronic aluminum foil products have strict requirements on process technology, equipment technology and production management level, production must strictly follow the process flow and equipment characteristics to produce qualified products.

In recent years, with the advancement of science and technology, the main equipment used in the production of electronic aluminum foil products has been domestically produced. Nowadays, domestic electronic aluminum foil factories use domestic equipment to produce products, and the quality level has caught up with or even exceeded the products produced by Japan and South Korea.

In the choice of control system, the technology possessed by major domestic manufacturers is not very mature, and most of them choose foreign control systems. In terms of technology, domestic production lines and production processes still imitate and continue to use foreign technology, or choose a technical model of cooperation with foreign capital.

capacitor used electronic aluminum foil

In order to continuously improve the product characteristics of aluminum electrolytic capacitors, my country has made many related technical improvements in aluminum foil processing. The use of high-purity, high-performance aluminum foil materials greatly improves the corrosion performance of the material, and at the same time greatly reduces the leakage current of the dielectric oxide film formed;

The development of advanced corrosion and formation processes further increases the specific capacity of the cathode and anode aluminum foils, 且陽極光箔的漏電流進一步降低. 以實現電容器的體積縮小化、扁平化, 化學成型鋁箔高比容高強度加工技術近年來已取得進展.
