1.What cov nyhuv tsis tshua muaj kub muaj rau corrosion tsis kam?
Corrosive Nruab Nrab Lub Xeev: Dej yog yooj yim rau kev ua kom haum rau hauv dej khov los yog dej, kua oxygen ua kom tsawg, thiab cov hluav taws xob electrochemical tsawg zuj zus.
Txheej Txheej Txheej Hloov: feem ntau cov txheej txheem organic muaj txwv molecular, thiab yog tias muaj cov kab nrib pleb me me, qhov kub thiab txias tuaj yeem ua rau muaj kev nthuav dav.
Corrosion Kuj:
Lub sij hawm luv luv corrosion yog qhov zoo, lub substrate Rust tus nqi yog qeeb, thiab txoj kev pheej hmoo tseem ceeb yog tias txheej teeb tsa nws cov teeb meem vim tias brittle brittle.
Qhov sib txawv ntawm cov txiaj ntsig sib txawv: Tom qab lub voj voog khov-thau ntawm qib pe no 3n / cm ntawm chav nyob hauv qab 3n / cm, thiab kev pheej hmoo ntawm cov loj loj nthuav dav; Thaum lub sij hawm fluorocarbon txheej txheem muaj cov molecular saw rigidity thiab zoo fresh tiv taus los ntawm tsuas yog 10%, thiab tawg nthuav dav heev.
2.Yog li cas chav sov muaj nyob rau corrosion tsis kam?
Corrosive Nruab Nrab Lub Xeev: Cov dej muaj nyob hauv lub xeev ua kua, oxygen solubility yog ib nrab, thiab electrochemical corrosion cov yeeb yam xwm txheej.
Txheej Txheej Pauv Hloov: Cov Txheej Txheem Ruaj Ntseg Zoo Tshaj Plaws - Cov Khoom Siv Hluav Taws Xob
Corrosion Kuj:
Corrosion tsis kam yog qhov ruaj khov tshaj plaws thiab ua tau raws li lub neej tsim lub neej ntawm txheej nws tus kheej.
Corrosion yog feem ntau concementrated hauv txheej tsis xws luag, manifested raws li "pitting" hauv zos ", thiab kev nthuav dav yog qeeb heev.
3.Yog li cas ua kom sov siab dua muaj qhov kub thiab txias muaj rau ntawm corrosion tsis kam?
Corrosive Nruab Nrab Lub Xeev: Dej Evaporates sai sai, tab sis nyob rau hauv high agity, kua dej tseem muaj zog, thiab cov pa hluav taws xob corrosion yog 2-3 zaug ntawm qhov kub ib txwm; Nyob rau tib lub sijhawm, siab kub yuav ua kom nrawm dua qhov nkag ntawm ntsev.
Hloov pauv ntawm Txheej Txheem Txheej:
Lub thermal lus tsa suab ntawm cov molecular chart ntawm cov organic txheej intensifies. Yog hais tias tus ntoo khaub lig-txuas ceev yog tsawg, "Thermal oxidation-laus" yuav tshwm sim - txheej txheej hloov xim, hmoov, thiab cov khoom muaj sia tsawg zuj zus.
Cov nplaum ntawm cov txheej thiab cov txheej txheem yuav txo qis vim qhov sib txawv hauv kev nthuav dav cov coefficients, thiab txawm tias "blistering" yuav tshwm sim.
4.Yog dab tsi cov av noo muaj ntawm corrosion tsis kam?
Corrosive Nruab Nrab Lub Xeev: Muaj cov dej kua me me hauv huab cua, thiab nws yog qhov nyuaj rau tsim zaj duab xis txuas ntxiv. Oxygen thiab ntsev tsis tuaj yeem ua tau zoo, thiab kev tiv thaiv corrosion yog yuav luag tsis zoo.
Txheej Txheej Hloov: Cov txheej yuav txo qis me ntsis vim yog ziab, tab sis cov molecular saw stability tsis cuam tshuam, thiab cov khoom nplaum thiab cov teeb meem nyob twj ywm zoo.
Corrosion Kuj: Lub corrosion tsis kam yog qhov zoo tshaj plaws, thiab nws yog qhov xwm txheej nrog cov txheej txheem qeeb tshaj plaws hauv txhua lub xyoo rau kev xeb substrate kom nthuav dav.
Qhov kev pheej hmoo tsuas yog tias cov hmoov me me vim yog ntev ziab, uas feem ntau tshwm sim hauv cov khoom muaj huab cua nyob hauv qab.
5.Yog li cas cov nyhuv high vaum muaj rau corrosion tsis kam?
Corrosive Nruab Nrab Xeev: noo noo hauv huab cua tuaj yeem yooj yim ua cov xim txuas ntxiv rau ntawm cov txheej txheem dej txuas ntxiv, thiab tuaj yeem ua kom nrawm dua hluav taws xob ntawm lub substrate.
Txheej Txheej Hloov:
Dej yuav nkag mus rau hauv txheej. Yog tias tus ntoo khaub lig-txuas ntom ntom ntawm txheej yog tsawg, "o" yuav tshwm sim, ua rau muaj adhesion tsawg dua.
Cov av noo yuav ua kom nrawm dua cov txheej kub, txo cov molecular qhov hnyav ntawm cov qauv, thiab dheev txo cov khoom thaiv.
Corrosion Kuj:
Corrosion yog muaj kev cuam tshuam hauv "Txheej av ntub dej" thaj chaw siab pe hawm rau ntawm 6 lub hlis hauv 1 xyoos yog 20%; Thaum hdp lossis PVDF tsho hlau muaj siab sib txuas ntom ntom ntom ntom thiab muaj zog hydrolysis tsis kam, thiab thaj tsam xeb hauv 1 xyoos feem ntau tsawg dua 5%.
