1. Pib nrog cov khoom ntawm cov raj xa dej thiab tswj nruj zoo ntawm cov khoom siv raw.
Nkag mus rau hauv kev lag luam rau cov yeeb nkab steel hlau thiab cov yeeb nkab steel hlau. Txhawm rau kom ntseeg tau tias cov ntaub ntawv ua tau raws li qhov xav tau. Hais txog kev xaiv cov khoom, ob qho tib si kev lag luam thiab kev txiav txim siab zoo raug txiav txim siab. Raws li kev ua haujlwm tshwj xeeb, austenitic stainless hlau nrog corrosion siab tsis kam, siab nickel cov ntsiab lus, duplex stainless hlau, titanium thiab titanium alloys, thiab iav steel tuaj yeem xam tau.
2.Qhov txheej tiv thaiv
Tam sim no, hauv kev pom ntawm kev xeb ntawm stainless hlau lub luj tshib kav dej hauv qab ib puag ncig, ntxiv rau kev xaiv ntawm cov khoom siv nrog kev muaj zog corrosion tsis kam, kev txhim kho corrosion kuj tseem tuaj yeem txhim kho los ntawm txheej txheej ntawm cov kav hlau xeb. Hauv kev pom ntawm cov nplaim qhov chaw yooj yim ntawm cov yeeb nkab steel hlau yeeb yaj kiab thiab qhov tsis zoo ntawm cov pa hlau ua kom yooj yim reducer los tiv thaiv xeb txheej ntawm nws cov nplaim, qhov txheej txheem zoo rau kev tiv thaiv kev xeb ntawm stainless hlau nyob rau hauv ib puag ncig marine tau tsim- epoxy hmoov txheej. Cov xim muaj xim tshiab yog hom xim tshiab uas yog kiag li dawb ntawm cov kuab tshuaj thiab muab txau rau hauv zaj duab xis hauv cov hmoov ntawv.
3. Kev tiv thaiv hluav taws xob
Cov tshuab hluav taws xob tiv thaiv txoj hauv kev tsuas yog muab nrog cov tiv thaiv kev tiv thaiv, kev tiv thaiv cathodic thiab kev tiv thaiv anode.
(1) Txoj hauv kev tiv thaiv kev tiv thaiv yog hais txog kev sib txuas nrog cov hlau nrog qis hluav taws xob muaj peev xwm thiab cov hlau tiv thaiv ua ke los ua cov roj teeb thawj. Cov hlau nrog cov qis dua qhov hluav taws xob muaj peev xwm yog yaj ua lub anode, thiab cov hlau tiv thaiv yog siv raws li cathode kom tsis txhob xeb.
(2) cov kev tiv thaiv kev tiv thaiv cathodic hais txog qhov sib ntxiv ntawm DC lub zog hluav taws xob, txuas cov hlau tiv thaiv mus rau qhov tsis zoo electrode li cathode, kom lub peev xwm ntawm kev tiv thaiv stainless hlau flange hlau tau kho tsis zoo los nkag rau thaj chaw tsis muaj xeb. ntawm daim duab E-pH daim duab; txuas cov hlau khib nyiab Mus rau qhov zoo electrode, raws li qhov anode ua cov khib nyiab hlau corrode thiab tiv thaiv cathode.
(3) Txoj kev tiv thaiv anode yog hais txog kev siv sab nraud DC lub zog hluav taws xob los txuas cov hlau tiv thaiv rau cov qhov khaus raws li qhov anode. Cov hluav taws xob muaj peev xwm txav tau rau hauv cov kev taw qhia zoo (piv txwv li, anode polarization) thiab nkag mus rau thaj chaw passivation ntawm E-pH daim duab los tiv thaiv cov hlau yog" passivated" thiab muaj kev tiv thaiv.
