Anti - Corrosion txij nkawm txoj kev rau phaj kub hloov chav nyob.
Vim tias lub chaw teeb hluav taws xob tsawg tsawg, cov pa hluav taws xob kom kub muaj teeb meem corrosion tom qab siv. Txhawm rau txhim kho tus nqi siv ntawm cov cuab yeej siv, anti - corrosion kuj yog ib qho ntawm cov haujlwm tseem ceeb.
TusCov Hluav Taws Xob Tshav Kub Kubyog kev sib pauv cua sov muaj kev sib pauv ntawm ntau lub phaj tshav kub sib hloov uas hloov cov dej kub los ntawm ib qho kua dej mus rau lwm qhov. Nws muaj cov kev sib pauv cua sov, txhua tus yog muaj li ntawm cov txheej txheem txhuas thiab kauv yas. Muaj qee qhov khoob ntawm cov phiaj txhuas thiab kauv cov kua, kom muaj kev sib xyaw ua ke ntawm cov neeg siv hluav taws xob muaj peev xwm ua tau raws li cov neeg siv khoom kom tau raws li cov kev xav tau sib txawv.
Lub corrosion siv nyob rau hauv lub txee cov dej txias yog suav nrog ntawm chromate, vim tias cov auromate ion nws tus kheej yog ib tug inhibitor ntawm cov txheej txheem anodic. Thaum muaj ib qho uas haum cathodic inhibitor, lawv hnov thiab sib txuas ua ke kom ua tiav peb arti- corrosion hom phiaj.
Chromate - {- polyphosphate yog siv rau kev tiv thaiv corrosion. Polyphosphate nws tus kheej muaj peev xwm ua rau muaj kev cuam tshuam corrosion thiab ntxuav cov hlau nto. Vim tias polyphosphate tuaj yeem hloov mus rau hauv orthophone tuaj yeem tsim cov calcium ions hauv dej, uas incripits lub ntsiab lus ntawm kev tiv thaiv corrosion.
Chromate -} zinc -} phosphate yog siv rau kev tiv thaiv corrosion. Lub hauv paus ntsiab lus ntawm kev siv sodium phosphate thiab polyphosphatphate zoo sib xws. Tus nqi ntawm cov phosphate application ib puag ncig yuav siab dua li polyphosphate. Phosphate tsuas yog tiv thaiv kev tsim cov nplai thiab tuaj yeem ua rau muaj ntsev calcium txawm tias hauv nruab nrab nrog tus nqi pH zoo li 9.
Chromate - zinc - hydrolyzed polyacrylamide yog siv rau kev tiv thaiv corrosion. Hydrolyzed polyacrylamide yog cationic copolymer uas muaj cov nyhuv divergent hauv dej thiab tuaj yeem inhibit nplai los ntawm tig mus rau hauv av.
Cathodic kev tiv thaiv thiab anodic tiv thaiv yog siv rau kev tiv thaiv corrosion. Cathodic kev tiv thaiv cuam tshuam nrog DC lub zog rau cov phaj cua sov ua kom kub tshuab hluav taws xob tshuab, tig mus rau hauv cathode, yog li muab kev tiv thaiv. Txawm li cas los xij, cov qauv no siv ntau npaum li cas ntawm lub zog thiab yog kim. Anodic kev tiv thaiv cuam tshuam nrog anode powered anode rau cov cua sov hloov pauv, uas tsim kom muaj kev sib tw ua yeeb yaj kiab ntawm cov hlau nto, kev ua tiav kev tiv thaiv corrosion.
Dab tsi yog anti - corrosion ntsuas?
Isti -} corrosion xim lossis anti- Corrosion txheej yuav tsum tau siv rau ntawm cov kav dej thiab cov thawv los tiv thaiv corrosion.
Siv anti - corrosion li qub thiab lwm yam anti - corrosion khoom los tiv thaiv corrosion.
Siv corrosion -} Cov ntaub ntawv resistant los tsim cov kav dej thiab cov thawv los tiv thaiv corrosion.
Txhim kho qhov kub thiab txias rau soj ntsuam qhov kub ntawm lubChav Ua Haujlwm Cua Sovlos tiv thaiv corrosion.
Nruab ib qho kev siv dej tsis siv neeg tshem tawm cov av hauv chav ua pa hluav taws xob kom tiv thaiv corrosion.
Nquag ntsuam xyuas lub chav ua pa hluav taws xob kom kuaj seb puas muaj kev tiv thaiv cov anti - corrosion ntsuas yog ua tau los tiv thaiv corrosion.
