○ Cathodic Protection Technolo照水gy

Open electrode protection is one o草新f the most effectiv麗爸e methods to prevent meta開自l electrochemical corrosion. It ap到靜plies a certain c區看athodic current to the pr亮數otected metal to ma山在ke it produce cathodic polarizati少業on. When the turtle position of the m動兵etal is negative to a certain potenti人鄉al value, the anodic dissolut民姐ion process of c城費orrosion will be effect麗路ively inhibited. According to the dif山金ferent ways of providi作線ng cathodic current, 看在cathodic protection can be divided into輛用 sacrificial anode m的吃ethod and impressed curr自離ent method. Sacr算花ificial anode m慢現ethod is to electrically connect a 雪少metal or alloy with a more negative pot子腦ential to the protected metal struc有暗ture, and provide protective curre鐵做nt to the broken protecti能生ve object through the continuous consu科西mption and dissolution of the electro答動negative metal or生就 alloy, so that the metal structu黃窗re can be protected.通文 The impressed current method is to弟東 convert the external alt呢讀ernating current into low voltage d聽來irect current, and transfer t學拍he protection curr朋樂ent to the protected metal structure t場綠hrough the auxiliary友會 anode, so as to inhibit th醫開e corrosion. The system 畫高measures the ink potential throug微睡h the reference electrode an離兒d reversely explodes the control 車去signal to the pote暗暗ntiostat to adjust the outpu有數t current, so that the metal s跳和tructure is in a good pro北窗tective state.

In general, the cost of cathodic p好身rotection only 行輛accounts for 1%-3% of t河務he cost of the p關知rotected metal s子土tructure, and th樂開e service life of the st木學ructure can be doubled or even doz廠林ens of times longer. As cathodi坐時c protection has the advantages of s短地imple equipment, convenient constructio黑電n and long protection time, it h內裡as been developed a路姐nd widely used in r老計ecent years. It is an applicable tech窗習nology with low investment資司, good effect and econo問要mic benefits.

The company has been engaged 區低in the research and application of cath哥兒odic protection technol學校ogy for many years. The com到視pany integrates t中謝he research and developm媽黃ent, design, production, constructio志筆n, and engineering c答南ontracting of openelectrodeprotection鐘水 technology and prod白知ucts. It has undertaken and了黑 completed nearly 1業票000 cathodic protection projects in呢個 the fields of ships, p校南ort engineering facilities, buried pipe有歌lines and pipe networks, pet放些rochemical industry, e姐購lectric power, marine engineeri商友ng, etc. The products and engineeri商秒ng achievements have spr友光ead throughout the country 厭謝and more than ten 白他countries and regions such as 從到the United States, Japan, Thailan嗎長d, Pakistan, Indonesia, Hong Kong, et秒讀c., and have achieved good 現風anti-corrosion effects.
