AC-1焊接鋁合金犧牲陽極保護Apply antiseptic coating to the inside of the water tank,用以將金屬與電介質環境電絕緣隔離,在水罐的內部均勻安裝若干塊鎂合金陽極作為犧牲陽極、罐體鐵板本身作為陰極,利用水作為電解質,使整個結構極化,形成一個二次腐蝕電池。陰極保護技術和涂層的聯合應用,陰極保護可有效地防止涂層破損處產生的腐蝕,延長涂層使用壽命,而涂層又可大大減少保護電流的需要量,改善保護電流分布,增大保護半徑,使陰極保護變得更為經濟有效,整個過程安全無害,有效的解決了消防水罐焊接處滲水的不足,操作簡單、安全性好、穩定可靠,便于推廣和應用。
犧牲陽極、鎂合金犧牲陽極、鋁合金犧牲陽極、鋅合金犧牲陽極、鎂帶、鋅帶、參比電極、測試樁、鎂合金棒、鋅接地電池、第二代防雨防盜測試樁、絕緣接頭、以及陰極保護輔助材料,長效參比電極和外加電流用的高硅鑄鐵陽極、恒電位儀等產品。
鋁合金密度低,但強度比較高,接近或超過優質鋼,塑性好,可加工成各種型材,具有優良的導電性、導熱性和抗蝕性,工業上廣泛使用,使用量僅次于鋼。一些鋁合金可以采用熱處理獲得良好的機械性能、物理性能和抗腐蝕性能。硬鋁合金屬AI—Cu—Mg系,一般含有少量的Mn,可熱處理強化.其特點是硬度大,但塑性較差。超硬鋁屬Al一Cu—Mg—Zn系,可熱處理強化,是室溫下強度的鋁合金,但耐腐蝕性差,高溫軟化快。鍛鋁合金主要是Al—Zn—Mg—Si系合金,雖然加入元素種類多,但是含量少,因而具有優良的熱塑性,適宜鍛造,故又稱鍛造鋁合金。
According to the construction of special points at the end of the pipe, no large pieces can be welded before the pinning of the pipe, so as not to prevent interference with the construction of the pile. The sun can only use underwater installation construction after completion of the pilling. The sun and the sun must be strong and reliable, and they must not be taken off for 30 years. The high density of protective power flow not only consumes a large amount of power, but also produces a negative effect, that is, what is called "over-protective phenomenon." There are several methods for underwater construction of the solar system: bolt fixation, bundling, and underwater welding.
根據鋼管樁碼頭建造特點,鋼管樁打樁前不能焊接任何較大構件,以免防礙打樁施工,犧牲陽極只能在完成打樁後采用水下安裝施工。犧牲陽極安裝必需牢固可靠,30年不脫落,與鋼管樁電性導通好。保護電流密度偏高,不僅消耗大量的電能,而且還會產生負作用,即發生所謂的『過保護』現象。犧牲陽極水下安裝施工的方法主要有以下幾種:螺栓固定法、捆紮法和水下電焊法。
