Xaiv cov kua degreaser uas tsis muaj zog alkaline thiab tsis corrode txhuas. Lub degreaser yuav tsum zoo dua yog tsis muaj cov tshuaj inorganic, tshwj xeeb tshaj yog nws yuav tsum tsis txhob muaj cov khoom siv inorganic xws li sodium nitrite, sodium silicate, metasilicate, caustic soda, sodium fluoride, sodium chloride, lossis chromium -muaj oxidizers.
Xws li cov khoom tsis yog -ferrous hlau ntxuav, nruab nrab degreasers, thiab lwm yam.
Yuav ua li cas xaiv tus corrosion inhibitor tom qab degreasing
Txij li thaum txhuas yog cov khoom muag muag, ib kauj ruam degreasing tsis txaus los tshem tawm cov roj uas tau nkag mus rau hauv txhuas. Yog li ntawd, kev tiv thaiv kev tiv thaiv txhuas txhuas yuav tsum siv cov tshuaj passivating lossis oxidizing cov neeg ua haujlwm nrog lub peev xwm degreasing, uas tuaj yeem tshem tawm cov roj tag nrho thaum tsim cov yeeb yaj kiab tsis muaj xim.
Xws li txhuas degreasing passivators, chromium -dawb degreasing thiab oxidizing tov, thiab lwm yam.
Cov qauv dab tsi yuav tsum muaj rau txhuas corrosion-cov tshuaj tiv thaiv passivation kho mob?
① Muaj kev ua haujlwm ntawm kev tshem cov roj thiab roj.
② Nws yog cov khoom lag luam zoo ib puag ncig thiab yuav tsum tsis txhob muaj chromium ions lossis lwm yam hlau hnyav thiab muaj zog oxidizing cov neeg ua haujlwm xws li npib tsib xee, tooj liab, txhuas, nitric acid, thiab lwm yam.
③ Organic corrosion inhibitors uas cuam tshuam rau adhesion, xws li silicates, sodium benzoate, sodium nitrite, emulsified ciab, thiab emulsified roj, tsis tuaj yeem siv los tiv thaiv corrosion.
④ Cov txheej txheej zaj duab xis passivated yog cov yeeb yaj kiab tsis muaj xim thiab pob tshab, thiab nyob rau lub sijhawm xav tau, yuav tsum tsis muaj xeb dawb lossis xim dub xeb ntawm lub ntsej muag txhuas.
⑤ Cov tshuaj acidic uas ua rau muaj kev cuam tshuam hnyav nrog txhuas, xws li fluorides, siv tsis tau.
