14kg鎂陽極保護(hù)年限20年詳情請(qǐng)咨詢
犧牲陽極填包料有用袋裝和現(xiàn)場(chǎng)鉆孔中填裝兩種方法,留意袋裝的袋子必需是自然纖維織品,嚴(yán)禁使用化纖織物。
犧牲陽極的分布可采用單支或集中成組兩種方式,陽極埋設(shè)分為立式,水平式兩種,埋設(shè)方向有軸向和徑向。成組埋設(shè)時(shí),陽極間距2～3m為宜。對(duì)化學(xué)填包料的基本要求有：
?、?陽極地床構(gòu)造
（泥土環(huán)境）
陽極安裝方式
14kg鎂陽極保護(hù)年限20年詳情請(qǐng)咨詢犧牲陽極組在管道上的間距,對(duì)于長(zhǎng)輸管道為1 ～2組/km,對(duì)于城市管道及站內(nèi)管網(wǎng)以200～300組為宜。常用填包料配方見附表：
為保證犧牲陽極在泥土中機(jī)能不亂,陽極周圍要填充適當(dāng)?shù)幕瘜W(xué)填包料,陽極與泥土相鄰為陽極與填料相鄰,改善了陽極的工作環(huán)境；降低陽極接地電阻,增加陽極輸出電流；填料的化學(xué)成份有利陽極產(chǎn)物的溶解,不結(jié)痂,減少不必要的陽極極化；維持陽極地床長(zhǎng)期潮濕。 rj2098555
⑵陽極地床的布置
14kg鎂陽極保護(hù)年限20年詳情請(qǐng)咨詢電阻率低,滲透滲出性好,不易流失；保濕性好。陽極埋設(shè)位置一般距管道外壁3～５m,小不宜小于0.3m,埋設(shè)深度以陽極頂部距地面不宜小于1m為宜,對(duì)于北方地區(qū),必需在凍土層以下?，F(xiàn)場(chǎng)鉆孔填裝效果雖好,但填料用量要大,稍不留意輕易把土粒帶入填料中,影響填包的質(zhì)量,填包料的厚度應(yīng)在各個(gè)方向均保持5～10cm。在地下水位低于3m的干燥地帶,犧牲陽極應(yīng)加深埋設(shè),對(duì)河流,湖泊地帶,犧牲陽極應(yīng)盡可能埋設(shè)在河床（湖底）的安全部位以防洪水沖涮和挖泥清淤時(shí)損壞。在城市和管網(wǎng)區(qū)使用犧牲陽極時(shí),要留意陽極和被保護(hù)構(gòu)筑物之間不應(yīng)有其它構(gòu)筑物,如電纜,水,汽,管道等。
The ribbon magnesium alloy sacrificial anode provided by our company has negative potential of magnesium anode, which produces large amount of electricity per unit mass. It is an ideal sacrificial anode material. It is applied to cathodic protection of metal structures in soil, fresh water and sea water. The magnesium alloy sacrificial anode is produced according to the national standard GB/T17731-2004 magnesium alloy sacrificial anode, and the anode used in the pipeline conforms to the SY/T0019-97 "design specification for the cathodic protection of the buried steel pipe sacrificial anode".
