镁牺牲阳极阴极保护：是将电位更负的金属与被保护金属连接，并处于同一电解质中，使该金属上的电子转移到被保护金属上去，使整个被保护金属处于一个较负的相同的电位下。
特点：该方式简便易行，不需要外加电源，很少产生腐蚀干扰。
应用：保护小型或处于低土壤电阻率环境下（土壤电阻率小于100欧姆.米）的金属结构。如：城市管网、小型储罐等。
一、辅助阳极安装
1、辅助阳极接线、密封
在土壤介质中，常用高硅铸铁做辅助阳极。
高硅铸铁辅助阳极密封步骤：
（1）将辅助阳极工作表面清理干净，除去阳极接头配件发浮绣，露出金属光泽。
（2）用铜焊或锡焊及螺栓连接方式将导线接在阳极接头配件上。
（3）辅助阳极与导线连接处，应确保连接牢固。导电性能良好。
（4）将固化剂和环氧树脂按比例调配均匀，在接头处涂抹及灌封，防止接线处渗水，做好绝缘密封处理。待环氧树脂固化后，按操作规程安装辅助阳极。

二、镁阳极与管道焊接
铝热焊的文字说明
1、首先要把管道的防腐层***一块,和铝热模具大小一样的长方形口
2、把镁阳极包上面的电缆线放在铝热焊模具下面的缺口处，在把模具放在管道上，模具盖打开能看到电缆，将小铁片碗形朝上放在模具底部
3、焊接分大包小包，先倒大包焊剂，在把小的引火粉均匀的倒在上面，顺便在模具点火口的边沿到点，然后把模具盖盖住
- 用点 在磨具口点火，（点火时注意带手套，脸不要直视点火口，用钳子压住模具盖）瞬间点燃，电缆线与管道焊接成一个铜疙瘩，焊接的非常牢固
- 然后用补伤棒将伤口填平ft20985552
- 用火加热补伤片，让补伤片紧贴上口，将伤口补住...

- Two, magnesium anode and pipe welding
- Description of thermit welding
- 1, first of all, destroy the anticorrosion layer of the pipeline, the same rectangle as the size of the aluminum hot mold.
- 2. The cable above the magnesium anode is placed under the gap under the aluminum heat welding mold. The mold is placed on the pipe. The die cover opens to see the cable, and the ***all iron sheet is placed upwa*** in the bottom of the mold.
- 3, the welding is divided into large package, first pour a large package of flux, in the ***all fire powder even on the top, by the way the edge of the mold point fire mouth to the point, and then cover the mold cover.
- 4. With the ignition of a point gun at the mouth of the grinding tool, (with the gloves on the ignition, the face not to look at the point of the fire, the lid is pressed with the pliers), it ignites instantaneously. The cable and the pipe are welded into a copper bump, and the welding is very strong.
- 5. Then fill the wound with a wound stick
- 6, use fire to heat up the wound piece, let the wound piece close to the mouth, fill the wound.焦作市立博轻合金股份有限公司
