可信賴的澆鑄鋁合金犧牲陽較

Reliable cast aluminum alloy sacrifice anode

 

 鋁合金犧牲陽較自溶性好，電流效率高，陽較發(fā)生電流的自調節(jié)性能好。適用于海水、淡水介質中的船舶、機械設備、海洋工程和海港設施以及低電阻率土壤中的管道、電纜等設施金屬防腐蝕的陰較保護。

用恒電流方法測定了３種Ａｌ－Ｚｎ－Ｉｎ系合金陽較的電化學性能，用金相顯微鏡和掃描電鏡技術（ＳＥＭ），分析了３種陽較材料的金相．結果表明：陽較晶粒越小，電流效率越高；陽較第二相數量越少，電流效率越高，但溶解不均勻；陽較的電流效率和溶解均勻性與第二相的優(yōu)先溶解—脫落有關

Planning and design are unreasonable. The planning and construction of the place where the accident occurred was chaotic, and the oil and gas pipelines were too close to the surrounding buildings. In particular, the cross-engineering design of the oil pipeline and the underdrain was unreasonable. The pipelines were suspended in the drainage underdrain, and there was a risk that the crude oil leaked into the drainage underdrain, and it was not conducive to daily maintenance. Causing serious security risks.
Reasonable arrangement of the process, duration, according to local conditions to cool the width of the work belt. Avoid the rainy season construction, after the completion of the operation to backfill and restore in time. Trench backfill should be stratified, and the near surface should be mixed with about 20 % of soil and certain nitrogen, phosphorus and potassium fertilizer to maintain soil fertility. When restoring the landform, we must combine the local conditions and carry out replanting of vegetation in a timely manner.
針對不同均勻化處理方式會引起合金微觀和電化學性能變化現(xiàn)象，采用電子探針（EPMA）、動電位較化及恒電流較化等方法研究不同熱處理（水淬、空冷、爐冷）方式對Al—Zn—In合金的微觀和合金在3％NaCl溶液中的開路電位、工作電位、腐蝕形貌和電流效率等電化學性能的影響。結果表明：510℃，10h的均勻化處理使晶界偏析減少，舒緩析氫自腐蝕和晶粒脫落，提高電流效率，但對陽較開路電位、工作電位及溶解行為的影響并不明顯，且水淬處理試樣的電流效率高。

鋁是一種輕金屬,其化合物在天然界中分布較廣,地殼中鋁的含量約為8%(重量),僅次于氧和硅,具第三位。
產業(yè)純鋁（鋁的含量98.0%-99.7%）。
我公司也可以根據客戶的不同需求設計并出產各種特殊規(guī)格和機能的鋁合金犧牲陽較。而常用鋁導線的導電度約為銅的61％，導熱度為銀的一半。固然純鋁較軟且富延展性，但仍可靠冷加工及做成合金來使它硬化。
