The structure of steel plastic copper ring consists a plastic circular core with a short rod in it. There is a copper wire of 250 mm~2 surface area covered the rod.
金塑铜环的结构是在塑料圈内加一立柱，立柱上缠绕250mm~2的钢丝，使之成为一种活性的环形IUD。
Metal positive pole is it mean in a certain metal surface is it cover one electrode electric potential lower metal material to plating to protect, it is at environment electric potential material not metal not lower corrode but not play by kinds of protective action at first in corroding (for instance: Steel surface plates and covers the metal zinc Metal negative pole is it mean in metal surface is it cover one electric potential higher corrosion-resistant metal material to plating to protect, in corroding at environment it have electric potential metal bag not complete not low covered, it have electric potential metal and corrosivity material not low isolated not coming (for instance: Steel surface copper facing Metal a superficial one nonmetal to is it is it protect to put, is it make apt to corrode metal material isolate from external environment condition but plays a role in protecting to paint in metal surface to scribble.
金属的阳极保护是指在某种金属表面镀覆一种电极电位较低的金属材料，在腐蚀环境中电位较低的金属材料首先被腐蚀而起到一种保护作用（如：钢铁表面镀覆金属锌）；金属的阴极保护是指在金属表面镀覆一种电位较高的耐腐蚀金属材料，在腐蚀环境中将低电位金属完全包覆，把低电位金属与腐蚀性物质隔绝开来；金属表面的非金属涂装保护，就是在金属表面涂漆使易腐蚀金属材料与外部环境隔离而起到保护作用。
