Cov ntaub ntawv ua los ntawm nickel tswj tau qhov ruaj khov ntawm cov qauv thiab tiv taus xeb ntawm qhov kub siab uas cov hlau tsis xeb yuav qaug zog lossis oxidize.
Yog li ntawd, rau kev lim dej kub heev, nickel lossis cov hlau nplaum siab heev feem ntau yog qhov kev xaiv zoo tshaj plaws.
5. Kev tiv thaiv xeb cuam tshuam li cas rau kev ua haujlwm ntawm cov lim dej?
Kev tiv thaiv xeb ncaj qha cuam tshuam rau lub neej ntev, kev ntseeg tau, thiab kev lim dej zoo ntawm cov lim hlau uas muaj qhov ntxig.
Thaum cov khoom siv lim dej xeb:
•Cov qauv ntawm qhov hws yuav lwj
•Qhov tseeb ntawm kev lim dej tuaj yeem tsis ruaj khov
•Lub zog kho tshuab txo qis
•Kev pheej hmoo ntawm kev ua qias tuaj ntxiv
Piv txwv li, nyob rau hauv cov chaw muaj chloride ntau, SS304 yuav xeb dhau sijhawm, ua rau kev ua haujlwm txo qis.
SS316L, nrog kev tiv thaiv corrosion zoo dua, tswj cov yam ntxwv lim dej ruaj khov nyob rau hauv tib qho xwm txheej.
Kev xaiv cov khoom siv zoo ua kom muaj kev ua haujlwm zoo ib yam thiab txo cov zaus txij nkawm thiab cov nqi hloov pauv.
6. Cov khoom siv twg pheej yig dua: SS304, SS316L, lossis nickel?
Los ntawm qhov pom ntawm tus nqi:
•SS304 → pheej yig tshaj plaws
•SS316L → tus nqi nruab nrab (siab dua 304 vim muaj cov ntsiab lus molybdenum)
•Nickel → kim dua heev
SS304 zoo tagnrho rau cov ntawv thov uas muaj kev cuam tshuam nrog tus nqi nrog rau cov xwm txheej ua haujlwm tsis hnyav.
SS316L muab qhov sib npaug ntawm tus nqi thiab kev ua tau zoo, ua rau nws yog cov khoom siv dav tshaj plaws hauv kev lim dej kev lag luam.
Nickel, thaum muab kev ua tau zoo tshaj plaws hauv qhov chaw ib puag ncig hnyav, feem ntau tsuas yog siv thaum tsim nyog tiag tiag vim nws tus nqi siab.
Qhov kev daws teeb meem uas pheej yig tshaj plaws tsis yog cov khoom siv pheej yig tshaj plaws, tab sis yog cov uas ua tau raws li qhov yuav tsum tau ua yam tsis muaj kev qhia tshwj xeeb ntau dhau.
7. Cov khoom siv zoo tshaj plaws rau cov tshuab lim roj uas muaj cov khoom huv siab yog dab tsi?
Rau cov tshuab roj uas muaj purity siab, xws li cov uas siv rau hauv kev tsim khoom semiconductor lossis cov cuab yeej analytical,
SS316L feem ntau yog cov khoom siv nyiam.
Qhov no yog vim:
•Kev tiv thaiv xeb zoo heev
•Cov pa roj carbon tsawg (txo qhov kev pheej hmoo ntawm kev ua qias tuaj)
•Cov qauv pore ruaj khov
•Kev sib haum xeeb nrog ultra- ib puag ncig huv si
Hauv qee qhov kev siv ultra-high purity (UHP), kev kho kom zoo nkauj ntxiv xws li electropolishing yuav raug siv rau SS316L kom txhim kho kev huv thiab txo cov khoom me me.
Feem ntau tsis tas yuav siv nickel tshwj tsis yog tias lub kaw lus muaj qhov kub thiab txias heev lossis raug tshuaj lom neeg hnyav.
8. Qhov ruaj khov ntawm qhov loj ntawm cov qhov (pore size stability) puas txawv ntawm SS304, SS316L, thiab nickel?
Yog, qhov ruaj khov ntawm qhov loj ntawm cov qhov (pore size stability) yuav txawv nyob ntawm cov khoom siv, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej ua haujlwm hnyav.
Txawm hais tias tag nrho peb cov ntaub ntawv tuaj yeem tsim tau nrog cov qauv pore meej thiab sib xws, lawv qhov ruaj khov mus sij hawm ntev txawv:
•SS304- Tej zaum yuav muaj kev puas tsuaj hauv cov chaw corrosive
•SS316L- Muaj kev ruaj khov zoo dua ntawm cov qauv thiab tshuaj lom neeg
•Nickel- Tswj qhov pore kom ruaj khov txawm tias nyob hauv qhov kub thiab txias heev thiab kev ntxhov siab ntawm tshuaj lom neeg
Rau cov ntawv thov uas xav tau kev lim dej kom raug thiab ruaj khov mus sij hawm ntev, tshwj xeeb tshaj yog nyob rau hauv cov chaw muaj kev kub ntxhov, SS316L lossis nickel yog qhov zoo dua li SS304.
9. Kuv yuav xaiv cov khoom siv zoo li cas rau kuv daim ntawv thov lim dej?
Kev xaiv cov khoom siv zoo yuav tsum tau soj ntsuam ntau yam tseem ceeb:
•Kub ua haujlwm
•Kev raug tshuaj lom neeg (corrosive los yog tsis)
•Cov xwm txheej siab
•Lub neej xav tau
•Kev txwv nyiaj txiag
Cov lus qhia yooj yim rau kev xaiv:
•Cov mob me me → SS304
•Corrosive los yog siab- cov chaw noo noo → SS316L
•Kub heev lossis raug tshuaj lom neeg → Nickel lossis cov hlau sib xyaw ua ke
Hauv ntau qhov xwm txheej kev lag luam, SS316L muab qhov sib npaug zoo tshaj plaws ntawm kev ua tau zoo, kev ua haujlwm ntev, thiab tus nqi.
10. Cov lim dej stainless hlau puas siv tau rau hauv cov chaw muaj tshuaj lom neeg hnyav?
Cov lim dej hlau tsis xeb siv tau rau hauv cov chaw muaj tshuaj lom neeg hnyav, tab sis kev xaiv qib yog qhov tseem ceeb heev.
SS304 muaj kev tiv taus tsawg rau cov kua qaub thiab chlorides muaj zog thiab tej zaum yuav xeb dhau sijhawm. SS316L, nrog kev tiv taus xeb zoo dua, ua haujlwm tau zoo dua hauv cov xwm txheej zoo li no thiab siv dav hauv kev ua tshuaj lom neeg thiab kev siv tshuaj.
Txawm li cas los xij, nyob rau hauv ib puag ncig uas muaj zog heev uas muaj cov kua qaub, alkalis, lossis kub siab, txawm tias SS316L kuj yuav tsis txaus. Hauv cov xwm txheej zoo li no, nickel lossis cov hlau tshwj xeeb xws li Hastelloy yuav tsum tau ua.
Kev xaiv cov khoom siv kom zoo ua kom muaj kev nyab xeeb thiab kev ua haujlwm mus sij hawm ntev.
