产品介绍 Introduction to product


基本结构组成:内部电缆、MMO 丝、预填包石


油煅后焦炭粉、纺织覆盖层层、长纤编织层。


Basic structural components: Internal cables,

MMO wires, pre-filled calcined petroleum coke powders,

fabric coating layers and long fiber

braid.


内部电缆:连续的内部电缆为阳极提供稳定的电流,为保证柔性采用 13 股铜线铰合。


Internal cables: no-stop inner cables provide stable current for the anode; and 13 strands of copper wires are hinged to ensure the flexibility.


MMO 丝:作为阳极主体,是在钛丝表面涂覆铱/钽氧化物的混合物


MMO wires: as an anode body, it is a mixture of iridium/tantalum oxide coated on the surface of titanium wires.


石油煅后焦碳粉


·降低辅助阳极与土壤之间的接触电阻;


·使电化学反应在辅助阳极(MMO/Ti 丝)周围的碳粉/土壤电解质之间进行,确保被保


护物体免受电化学腐蚀,延长辅助阳极的使用寿命。


Calcined petroleum coke powders:


The contact resistance between the auxiliary anodeand soil is reduced;


Electrochemical reaction is performed between the carbon powder around the auxiliary anode (conductive polymer or MMO/Ti wire) and soil electrolyte, so as to prevent the protected matters from being subjected to electrochemical corrosion and prolong the service life of the auxiliary anode

纺织覆盖层


·将碳粉以环形和一定的装填密度包覆在阳极周围,保证碳粉在储运、施工和使用过程


中不致位移、松动、散落而影响柔性阳极的正常使用及寿命。


·应具有良好的耐磨性、耐刺扎性和机械强度;


·自身应具有耐腐蚀性,这对于在水中的应用更为重要。


Fabric Jecket:


·The carbon powder shall be coated around the anode in a circular shape and with a certain filling density, so as to make the carbon powder not moved, loosened and dropped off in the process of storage and transportation, construction and use to affect the normal use and service life of the flexible anode.


·It shall have excellent wear resistance, puncturing resistance and mechanical strength;


It shall have corrosion resistance, which is very important to apply under water.




长纤编织层


·柔性阳极在施工安装时,保护纺织覆盖层不受磨损,进一步束紧、固定碳粉和纺织覆盖


层。


·应具有良好的耐磨性和机械强度;


·自身应具有耐腐蚀性,这对于在水中的应用更为重要。 protective braid:


·During construction and erection, the textile coating shall be prevented from wearing by the flexible anode, so as to further restrain and fix the carbon powder and the fabric coating.


· It shall have excellent wear resistance and mechanical strength;


·It shall have corrosion resistance, which is very important to apply under water.
