Galvanic corrosion tuaj yeem ua tau raug tiv thaiv los ntawm tus lej ntawm cov txheej txheem: Xaiv cov hlau/cov hlau nplaum kom ze ua ke raws li qhov ua tau hauv galvanic koob. Zam qhov chaw tsis zoo cuam tshuam los ntawm qhov anode me thiab cov cathode loj. Xim cov cathode (orboth) thiab khaws cov txheej txheej kom kho tau zoo ntawm theanode.
Kuj tseem paub yog, cov xim puas yuav tiv thaiv galvanic corrosion?
Xim muaj lub peev xwm los ua txoj haujlwm no hauv qee qhov xwm txheej. Xim muab barrier tiv thaiv tomaterials uas yuav kuj ua haujlwm kom txo qis rau anelectrolyte thiab ua kom nrawm dua xeb txheej txheem ntawm a galvanic cell.
Kuj Paub, dab tsi ua rau cov hlau tsis sib xws? Galvanic xeb yog ua nws tus kheej-induced tam sim no tsim los ntawm hluav taws xob muaj peev xwm ntawm ob cov hlau sib txawv nyob rau hauv kev sib cuag nrog ib tug electrolyte. Nws tuaj yeem tshwm sim thaum ob cov hlau sib txawv (xws li cov raj tooj liab thiab cov yeeb nkab hlau) tau txuas nrog thaum muaj cov electrolyte. Freshpotable dej yog ib qho tsis muaj zog electrolyte.
Hauv qhov no, yuav ua li cas galvanic corrosion tshwm sim?
Galvanic corrosion , tseem hu ua bimetallic xeb , yog txheej txheem electrochemical uas yog ib qho hlau corrodes nyob rau hauv kev nyiam rau lwm cov hlau uas nws yog nyob rau hauv kev sib cuag nrog ib tug electrolyte. Galvanic corrosion tshwm sim thaum twodissimilar hlau uas yog immersed nyob rau hauv ib tug conductive tov thiab yog txuas nrog hluav taws xob.
Koj yuav tiv thaiv kom tsis txhob xeb li cas?
Tiv thaiv tawm tsam kev txhim kho corrosion hauv cov khoom siv uas twb muaj lawm, nco ntsoov ntws tag thiab qhuav ib qho khoom muaj feem cuam tshuam nrog dej lossis lwm yam kev daws teeb meem thiab zam tsim kom tsis muaj mob uas tuaj yeem txhawb nqa xeb . Ntxiv thiab, nrhiav qhov uas twb muaj lawm qhov quav nyob rau hauv kev sib tshooj sib koom ua ke thiab siv txuas txuas txuas lossis muag khoom kom kaw qhov sib txawv.

Koj yuav txo qhov o hauv koj lub taub hau li cas?
Osmotherapy Osmotherapy yog txheej txheem txhais tau tias tshem tawm dej ntawm lub hlwb. Qhov no yog ua tiav siv cov tshuaj osmotic xws li mannitol, lossis cov ntsev ntsev ntau. Osmotic txoj kev kho kuj pab txhim kho ntshav khiav. Qhov no yuav pab txo qhov o thiab ICP hauv lub taub hau
Yuav txo qis co2 ntawm lub tshuab ua pa li cas?
Hypercapnia: Txhawm rau hloov kho CO2 cov ntsiab lus hauv ntshav ib tus xav tau hloov kho qhov pa tawm. Txhawm rau ua qhov no, qhov ntim dej lossis qhov ua pa yuav raug cuam tshuam nrog (T qis thiab P Tsawg hauv APRV). Tsa tus nqi lossis ntim dej, nrog rau nce T qis, yuav ua rau muaj cua nkag thiab txo CO2

Feem ntau dhau los, cov neeg mob kub siab saib ua ntej rau cov tshuaj tiv thaiv kab mob. Qes cov rog. Noj Me Me. Tsiv Tom Qab Noj Mov. Pw tsaug zog nce. Xav txog Koj Cov Tshuaj. Zom cov pos hniav. Ci Soda
Vim li cas galvanic corrosion tshwm sim?
Galvanic corrosion tshwm sim thaum ob lub dissimilarmetals raus rau hauv kev daws teeb meem thiab tau txuas nrog hluav taws xob. Ib qho hlau (cathode) raug tiv thaiv, hos lwm qhov (anode) yog corroded. Tus nqi ntawm kev tawm tsam ntawm anode tau nrawm dua, piv rau tus nqi thaum cov hlau raug sib cais
Yuav ua li cas yog tias GFR txo qis?
Yog tias GFR qis dhau, cov zom zaub mov hauv lub cev yuav tsis raug lim los ntawm cov ntshav mus rau hauv lub raum tubules. Yog tias GFR siab dhau, lub peev xwm nqus ntsev thiab dej los ntawm lub raum tubules dhau mus
