Hais txog cov txheej txheem tshuaj lom neeg cov twj, lawv tau siv ntau dua thiab siv dav hauv kev tsim khoom, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj, cov txheej txheem tshuaj corrosion-resistant cov twj yog nce ua lub luag haujlwm tseem ceeb. Raws li ib txwm muaj, vim qhov tshwj xeeb ntawm ib puag ncig uas siv cov txheej txheem tshuaj, lawv feem ntau yog ua los ntawm hlau lossis fluoroF46. Rau cov hlau zoo tib yam, lawv cov qauv tsis tshua muaj kev cuam tshuam rau corrosion, thiab qhov chaw sab nraud xws li kub, av thiab huab cua Nws yuav ncaj qha ua rau hlau corrosion, yog li peb cov khoom siv rau cov txheej txheem tshuaj tiv thaiv corrosion-resistant yog stainless hlau thiab fluoroplastic F46.

Qhov nruab nrab haum rau cov txheej txheem tshuaj twj tso kua mis yog qhov yooj yim corrosive, thiab rau kev faib tawm ntawm corrosion, feem ntau muaj ob txoj kev faib tawm.

Lub tshuab yog cais, thiab lwm yam yog cais raws li qhov ua rau thiab cov tsos ntawm corrosion. Raws li cov txheej txheem ntawm corrosion, nws tuaj yeem muab faib ua electrochemical corrosion thiab tshuaj corrosion. Electrochemical corrosion feem ntau yog hais txog qhov tshwm sim ntawm corrosion tshwm sim los ntawm cov tshuaj tiv thaiv electrode nyob rau saum npoo ntawm cov khoom hlau tom qab nws los rau hauv kev sib cuag nrog cov tshuaj electrolyte. Cov tshuaj tiv thaiv no feem ntau yog cov tshuaj tiv thaiv redox, thiab cov ntsiab lus tseem ceeb yog cov av noo thiab kub ntawm ib puag ncig; Tshuaj corrosion yog hais txog cov tshuaj tiv thaiv muaj zog ntawm cov hlau nto thiab ib puag ncig nruab nrab, uas ua rau cov hlau puas rau qee yam. Lub ntsiab yog vim li cas rau qhov corrosion yog kub thiab qhuav ib puag ncig. Raws li cov tsos thiab ua rau corrosion, nws tuaj yeem muab faib ua corrosion corrosion, industrial atmospheric corrosion, kub oxidation corrosion thiab marine atmospheric corrosion.

Nyob rau hauv ib puag ncig uas muaj kuab paug loj heev, vim hais tias muaj ntau yam volatile yam xws li sulfide, carbon dioxide thiab hydroxide nyob rau hauv cov huab cua, thiab kuj muaj ib co muaj plua plav, cov no yog xov xwm uas yooj yim rau corrosion. Thaum cov xov xwm no nyob rau hauv ib qho chaw ntub dej, cov pa roj acid yuav ua ke nrog dej los tsim cov inorganic acids. Cov acids no muaj zog corrosive zog, yog li lawv yuav induce corrosion. Nyob rau hauv ib puag ncig ntawm kev lag luam cua, cov cuab yeej yog tshwm sim los ntawm kev sib xyaw ua ke ntawm electrochemical corrosion thiab ncaj qha tshuaj corrosion. Lub ntsiab lus ntawm txhua qhov corrosion yog qhov ua tau zoo ntawm cov txheej txheem oxidation uas cov hlau tsis muaj electrons los ua ions. Qhov sib txawv tseem ceeb ntawm electrochemical corrosion thiab industrial atmospheric corrosion yog qhov sib txawv ib puag ncig uas lawv tshwm sim.

Kev xeb ntawm cov khoom siv zoo sib xws nrog cov khoom siv ntawm cov khoom siv. Hauv kev xaiv cov khoom siv tshuaj, peb yuav tsum tsom mus rau qhov tshwm sim ntawm corrosion, ua tib zoo xaiv cov khoom tsim nyog, thiab xav txog cov khoom ntawm qhov nruab nrab, qhov kub thiab txias ntawm ib puag ncig thiab kev khiav hauj lwm siab, thiab lwm yam. chemical kev lag luam Cov kev xav tau ntawm cov khoom siv raw thiab cov qauv thiab hom khoom siv tsim. Kev tsim cov qauv yuav tsum tsom mus rau qhov yuav tsum tau ua thiab cov yam ntxwv ntawm kev ntxhov siab hauv kev tsim khoom thiab kev ua haujlwm ntawm cov cuab yeej siv tshuaj, thiab cov hauv qab no yuav tsum tau them nyiaj mloog rau hauv kev tsim: ua ntej, cov txheej txheem ntawm cov khoom yuav tsum tau ua raws li kev xeb. cov kev cai ntawm kev tsim cov khoom siv tshuaj lom neeg; thib ob Nws yog ib qho tsim nyog yuav tsum tau them sai sai rau kev ua haujlwm ruaj khov thiab du ntawm cov cuab yeej siv tshuaj, los tiv thaiv kev ncua ntawm corrosive media, kev faib tsis sib xws ntawm cov khoom siv hluav taws xob, qhov sib xyaw ntawm cov pa thiab cov khoom sib txuam ntawm corrosion; Thaum kawg, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo saib xyuas kev tiv thaiv sab nraud los tiv thaiv kev qaug zog corrosion los ntawm kev sib hloov kev ntxhov siab.
