Corrosion Resistance Tsim thiab Kev Siv Cov Cuab Yeej Cuab Yeej Cuab Yeej hauv Cov Ib puag ncig hnyav

Hauv ntau qhov kev tsim khoom lag luam, cov tshuab cua sov yuav tsum tau ua haujlwm hauv qhov chaw hnyav xws li corrosion, av noo thiab kub, thiab corrosion kuj ntawm lub rhaub ncaj qha txiav txim siab nws lub neej kev pab cuam thiab kev nyab xeeb ntawm kev ua haujlwm. Ib puag ncig hnyav yuav ua rau muaj kev puas tsuaj rau cov cua sov thiab cov qauv sab hauv, ua rau lub rwb thaiv tsev tsis ua hauj lwm, to thiab txawm burnout, cuam tshuam rau kev ua haujlwm ntawm tag nrho cov cua sov. Raws li kev siv hauv kev lag luam, tsab xov xwm no tham txog kev tiv thaiv corrosion tsim ntawm lub tshuab cua sov thiab lawv daim ntawv thov nyob rau hauv ib puag ncig hnyav, muab cov ntaub ntawv siv rau kev xaiv cov cua sov tsim nyog hauv qhov chaw tshwj xeeb.
Hnyav kev lag luam ib puag ncig uas ua rau corrosion rau lub tshuab cua sov feem ntau suav nrog cov tshuaj cog corrosive gas ib puag ncig, marine humid ntsev tsuag ib puag ncig, zaub mov ua kua qaub thiab alkali ib puag ncig, thiab electroplating Rhiav ua kua corrosion ib puag ncig. Nyob rau hauv cov cheeb tsam no, zoo tib yam stainless hlau cartridge rhaub tau yooj yim corroded los ntawm acid, alkali, ntsev thiab lwm yam khoom, ua rau xeb, tawg thiab perforation ntawm lub sheath, thiab corrosive tshuaj nkag mus rau hauv lub sab hauv, ua rau lub coil tiv thaiv thiab rwb thaiv tsev txheej, ua rau lub rhaub tsis ua hauj lwm. Yog li ntawd, cov khoom siv hluav taws xob uas siv rau hauv qhov chaw hnyav yuav tsum tau txais cov qauv tsim kev tiv thaiv corrosion los txhim kho lawv cov kev hloov pauv ib puag ncig.
Lub hauv paus ntawm corrosion kuj tsim ntawm cartridge rhaub yog xaiv corrosion-cov ntaub ntawv tiv thaiv sheath. Qhov sib txawv corrosive ib puag ncig yuav tsum tau sib txawv cov ntaub ntawv: rau cov kua qaub thiab alkali corrosive gas ib puag ncig, 316 stainless hlau uas muaj zog corrosion kuj yog qhov zoo dua, uas muaj kev tiv thaiv zoo rau feem ntau cov tshuaj corrosive thiab tsis yooj yim rau xeb; Rau marine ntsev tsuag ib puag ncig nrog cov ntsiab lus chloride ion siab, Hastelloy alloy lossis titanium alloy sheath nrog cov ntsev tsuag zoo heev yuav tsum raug xaiv, uas tuaj yeem tiv taus cov tshuaj chloride ion corrosion thiab ntev kev pab cuam lub neej; rau cov kua qaub muaj zog thiab muaj zog alkali ua kua ib puag ncig, PTFE coated los yog ceramic sheath cartridge tso cua sov yog tsim nyog, nrog rau cov tshuaj zoo heev stability thiab tsis muaj cov tshuaj tiv thaiv nrog muaj zog corrosive xov xwm.
Sealing qauv tsim yog lwm lub ntsiab lus tseem ceeb ntawm kev tiv thaiv corrosion ntawm cartridge rhaub. Nyob rau hauv cov av ntub thiab ua kua-ib puag ncig, cov dej noo thiab cov kua corrosive yooj yim nkag mus rau hauv lub rhaub los ntawm cov hlau lead hlau qhov hluav taws xob thiab qhov kawg npog, ua rau cov rwb thaiv tsev sab hauv damp thiab corrosion. Yog li ntawd, corrosion-resistant cartridge heaters txais yuav ntau- txheej sealing tsim: cov hlau lead feem siv siab -kub resistant waterproof sealing kua nplaum, kawg cover yog welded thiab kaw nrog precision laser, thiab qhov sib txawv ntawm cov hlau lead hlau thiab lub sheath yog sau nrog corrosion- tiv thaiv sealing khoom, tag nrho thaiv qhov nkag ntawm noo noo thiab corrosive. Cov qauv kaw no tuaj yeem ua kom muaj qhov ziab ntawm lub rhaub dej hauv qhov chaw hnyav thiab tiv thaiv cov coil tiv thaiv thiab rwb thaiv tsev txheej los ntawm corrosion.
Cov khoom siv sab hauv los tiv thaiv- kev kho corrosion kuj tseem txhim khu kev tiv thaiv corrosion ntawm lub tshuab cua sov. Internal resistance coil siv npib tsib xee-chromium alloy nrog zoo corrosion kuj, tsis txhob oxidation thiab corrosion nyob rau hauv siab - kub thiab corrosive ib puag ncig; lub filling magnesium oxide txais siab -purity corrosion- qib resistant, tom qab kev kho tshwj xeeb ziab, tsis muaj ya raws thiab impurities, kom ntseeg tau zoo rwb thaiv tsev kev ua tau zoo thiab tshav kub hloov efficiency. Rau qhov tshwj xeeb muaj zog corrosion scenarios, cov qauv sab hauv kuj tuaj yeem kho nrog kev tiv thaiv -corrosion txheej los txhim kho kev tiv thaiv - muaj peev xwm corrosion.
Cov txheej txheem kho deg yog ib qho kev pab txhais tau tias txhawm rau txhim kho corrosion tsis kam ntawm cov cua sov cartridge. Rau cov hlau sheath heaters, passivation kev kho mob, electro- polishing los yog anti- corrosion txheej spraying tuaj yeem nqa tawm ntawm qhov chaw: passivation kev kho mob ua ib tug ntom oxide zaj duab xis nyob rau saum npoo ntawm stainless hlau, txhim khu nws corrosion kuj; electro- polishing ua rau lub tshuab cua sov kom du thiab huv si, txo cov adhesion ntawm cov khoom corrosive thiab yooj yim ntxuav; anti-corrosion txheej txau ua ib txheej tiv thaiv ntawm qhov chaw, cais lub rhaub los ntawm cov xov xwm corrosive. Cov txheej txheem kho saum npoo no tuaj yeem ua rau qeeb qeeb ntawm corrosion ntawm lub rhaub hauv qhov chaw hnyav.
Hauv cov cua sov ua ke nrog cov kav dej kub, qhov kev tiv thaiv corrosion tsim ntawm cov khoom siv cua sov yuav tsum tau muab sib xyaw nrog cov kav dej kub. Lub plhaub cua sov kuj tseem siv cov khoom siv corrosion- tiv taus, thiab kev sib txuas ntawm cov yeeb nkab cua sov evaporation seem thiab lub tshuab hluav taws xob lub tshuab hluav taws xob tau txais kev sib khi los tiv thaiv -corrosion tsim los tiv thaiv cov khoom corrosive los ntawm kev nkag mus rau qhov sib txawv. Cov cua kub sib xyaw ua ke ntawm corrosion-cov khoom siv hluav taws xob tiv thaiv cov cua sov thiab cov kav dej kub tuaj yeem paub txog cov cua sov hloov pauv hauv qhov chaw hnyav, ua kom muaj kev ruaj ntseg ntawm cov cua sov.
Hauv kev siv cov tswv yim, xaiv corrosion-cov khoom siv hluav taws xob tiv thaiv kab mob kuj yuav tsum tau xav txog qhov ntsuas kub thiab corrosion ntawm ib puag ncig. Rau siab - kub thiab muaj zog corrosion dual hnyav ib puag ncig, nws yog ib qho tsim nyog los xaiv cov ntaub ntawv uas muaj ob qho tib si kub tsis kam thiab corrosion kuj, xws li Incoloy alloy, kom tsis txhob muaj cov khoom degradation ntawm qhov kub thiab txias thiab tsis muaj corrosion kuj. Nyob rau tib lub sijhawm, ntxiv dag zog rau kev saib xyuas txhua hnub, tsis tu ncua ntxuav cov khoom corrosive uas txuas rau lub tshuab cua sov, xyuas cov sealing thiab sheath kev ncaj ncees, thiab hloov cov cua sov puas thaum lub sijhawm.
Kev txhim kho corrosion tsim ntawm lub tshuab cua sov yog tus yuam sij kom ntseeg tau tias lawv txoj haujlwm ruaj khov hauv qhov chaw hnyav. Kev tshawb fawb txog kev txhim kho corrosion- cov ntaub ntawv resistant, optimized sealing qauv thiab kev kho saum npoo tuaj yeem txhim kho cov kev tiv thaiv kev tiv thaiv -corrosion peev xwm ntawm cov cua sov, ua kom ntev kev pab cuam lub neej thiab txo nqi txij nkawm. Hauv tshuaj, dej hiav txwv, zaub mov thiab lwm yam kev lag luam nrog hnyav corrosive ib puag ncig, xaiv cov kev tshaj lij corrosion-cov khoom siv hluav taws xob tiv thaiv hluav taws xob yog qhov kev lees paub zoo rau kev ua haujlwm ntawm cov cua sov.
