廣州鋁合金犧牲陽(yáng)極價(jià)格
Guangzhou aluminum alloy sacrifice anode price
鋁陽(yáng)極的焊接時(shí)采購(gòu)多種焊接方式,在不同位置焊接采用不一樣的焊接,鋁陽(yáng)極可以做成支架樣式或者是平貼的直接焊接在設(shè)備上,起到保護(hù)作用嗎,還可以做成擰螺絲的樣式,圓形、螺栓樣式,單支架的,還有其他異行的樣式。
犧牲陽(yáng)極體通過(guò)自身腐蝕產(chǎn)生的電流對(duì)受保護(hù)金屬設(shè)施(如變電站的接地網(wǎng))進(jìn)行陰極極化,使之變成一個(gè)大陰極,從而防止金屬腐蝕,此即所謂的陰極保護(hù)。犧牲陽(yáng)極法簡(jiǎn)單易行,無(wú)須維護(hù),它是在被保護(hù)的接地網(wǎng)上連接電位更負(fù)、更容易腐蝕的金屬或合金(如鎂及鎂合金陽(yáng)極),靠陽(yáng)極的腐蝕溶解產(chǎn)生電流達(dá)到保護(hù)陰極(接地網(wǎng))的目的。犧牲陽(yáng)極陰極保護(hù)是接地網(wǎng)陰極保護(hù)中常用的保護(hù)方式。

鋁合金密度低,但強(qiáng)度比較高,接近或超過(guò)優(yōu)質(zhì)鋼,塑性好,可加工成各種型材,具有優(yōu)良的導(dǎo)電性、導(dǎo)熱性和抗蝕性,工業(yè)上廣泛使用,使用量?jī)H次于鋼。一些鋁合金可以采用熱處理獲得良好的機(jī)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(qiáng)化.其特點(diǎn)是硬度大,但塑性較差。超硬鋁屬Al一Cu—Mg—Zn系,可熱處理強(qiáng)化,是室溫下強(qiáng)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(yōu)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.
