Cov ntaub ntawv tshwj xeeb thiab txheej txheej ntawm cov hlab ntsha tiv thaiv corrosion tso cai rau lawv tiv taus cov kua qaub thiab corrosive cov yam ntxwv ntawm hydrogen chloride, ua rau lawv tsim nyog rau kev siv hauv cov kev xav tau roj no.
Corrosion-resistant micro cua sov raj tuaj yeem ua kom haum cov kua qaub, suav nrog nitric acid (HNO₃). Hauv cov chaw sim thiab cov chaw lag luam uas siv nitric acid rau kev siv xws li etching, hlau ntxuav, los yog tshuaj ntsuam xyuas, cov cua kub yuav siv tau los ua kom qhov kub ntawm cov kua qaub. Hauv chav kuaj hlau ua tiav, lub tshuab cua sov micro tuaj yeem siv los ua kom sov cov tshuaj nitric acid rau etching ntawm cov qauv hlau. Lub raj muaj kev tiv thaiv corrosion ua rau nws ua haujlwm zoo hauv qhov chaw acidic, muab cov cua sov tsim nyog rau cov txheej txheem etching yam tsis muaj kev puas tsuaj sai. Lub peev xwm los tiv thaiv cov teebmeem corrosive ntawm nitric acid tau lees tias lub raj cua sov tuaj yeem txhawb nqa nws txoj haujlwm nyob rau lub sijhawm, ua kom yooj yim rau kev sim thiab rov ua dua tshiab lossis kev lag luam.
Corrosion-resistant micro cua sov raj kuj tau sib xws nrog cov tshuaj alkaline. Sodium hydroxide (NaOH), uas yog cov alkaline sib xyaw ua ke, yog siv thoob plaws hauv ntau qhov chaw, suav nrog xab npum tsim thiab tswj dej khib nyiab. Hauv cov chaw tsim khoom siv xab npum, cov raj cua sov micro tuaj yeem siv los ua kom qhov kub ntawm cov tshuaj sodium hydroxide thaum lub sij hawm saponification txheej txheem. Cov raj yog tsim los tiv thaiv cov khoom corrosive ntawm cov tshuaj alkaline, lav cov cua sov uas muaj kev ntseeg siab thiab txhim kho kev tsim cov xab npum zoo. Lawv lub peev xwm rau acclimatise rau alkaline milieu ua kom yooj yim rau kev tswj hwm qhov kub thiab txias tseem ceeb rau cov txheej txheem tshuaj lom neeg koom nrog hauv kev tsim cov xab npum. Hauv cov chaw kho dej khib nyiab, sodium hydroxide tuaj yeem siv los tswj cov pH ntawm cov dej ntws tawm, thiab cov kav dej corrosion-resistant tuaj yeem muab cov cua sov tsim nyog rau ntau txoj kev kho mob yam tsis muaj kev puas tsuaj los ntawm cov kab mob alkaline. Lub peev xwm los hloov mus rau ntau yam kev daws teeb meem alkaline ua rau cov cua kub me me yog qhov tseem ceeb hauv ntau txoj kev lag luam.
Tsis tas li ntawd, corrosion-resistant micro cua sov raj muaj peev xwm tiv taus cov kuab tshuaj organic xws li ethanol thiab acetone. Hauv kev lag luam tshuaj thiab tshuaj lom neeg, cov kuab tshuaj no feem ntau siv rau kev rho tawm, ua kom huv, thiab cov txheej txheem sib xyaw. Cov raj cua sov muaj peev xwm ua kom cov kuab tshuaj organic mus rau qhov kub thiab txias rau cov txheej txheem no. Nyob rau hauv cov txheej txheem tshuaj extraction siv ethanol, lub micro cua sov raj enables meej thiab tswj cov cua sov, li no assured lub zoo extraction ntawm active Cheebtsam. Lub raj qhov kev tiv thaiv corrosion yog qhov tseem ceeb, vim qee cov kuab tshuaj organic tuaj yeem ua rau muaj kev cuam tshuam thiab tuaj yeem ua rau muaj kev xeb thaum lub sijhawm. Cov cuab yeej tshwj xeeb thiab cov ntaub ntawv ntawm cov hlab ntsha corrosion-resistant tso cai rau lawv ua rau cov tshuaj lom neeg zoo ntawm cov kuab tshuaj organic, ua kom muaj kev cia siab rau cua sov thiab txhim kho kev ua tau zoo ntawm ntau daim ntawv thov kev lag luam uas siv lawv.
Corrosion-resistant micro cua sov raj tuaj yeem ua kom haum rau ntau hom roj thiab kua, suav nrog sulfur dioxide, hydrogen chloride, acidic daws xws li nitric acid, alkaline tshuaj xws li sodium hydroxide, thiab cov kuab tshuaj organic xws li ethanol thiab acetone.
