Kev ua tau zoo ntawm cov saw hlau tsis xeb hauv cov chaw ntub dej

Kev ua tau zoo ntawm cov saw hlau tsis xeb hauv cov chaw ntub dej
Hauv ntau yam kev siv hauv kev lag luam thiab kev lag luam, cov saw hlau yog cov khoom tseem ceeb rau kev sib kis thiab kev thauj mus los, thiab lawv cov kev ua tau zoo thiab kev ruaj khov yog qhov tseem ceeb heev. Cov saw hlau tsis xeb ua tau zoo hauv cov chaw ntub dej vim lawv cov khoom siv tshwj xeeb, ua rau lawv yog thawj qhov kev xaiv rau ntau qhov chaw ua haujlwm hnyav. Tsab xov xwm no yuav tshawb nrhiav tob txog kev ua tau zoo ntawm cov saw hlau tsis xeb hauv cov chaw ntub dej, suav nrog lawv qhov kev tiv thaiv corrosion, lub zog, thaj chaw siv, thiab kev txij nkawm.

1. Kev tiv thaiv xeb ntawm cov saw hlau tsis xeb
Cov khoom siv tseem ceeb ntawm cov saw hlau stainless hlau yog stainless hlau, uas feem ntau muaj cov ntsiab lus xws li chromium thiab nickel, uas ua rau stainless hlau tiv taus xeb zoo heev. Hauv qhov chaw ntub dej, cov saw hlau carbon yooj yim ua rau tshuaj lom neeg nrog dej thiab oxygen los ua xeb, ua rau cov saw hlau ua haujlwm tsis zoo lossis tawg. Cov saw hlau stainless hlau tuaj yeem tiv taus qhov xeb no, tswj kev ncaj ncees ntawm lawv qhov chaw thiab kev ruaj khov ntawm lawv cov kev ua tau zoo.

(I) Lub hauv paus ntsiab lus ntawm kev tiv thaiv corrosion
Qhov kev tiv thaiv xeb ntawm cov hlau tsis xeb feem ntau yog los ntawm cov zaj duab xis chromium oxide ntom ntom uas tsim rau ntawm nws qhov chaw. Cov zaj duab xis no tuaj yeem cais cov dej thiab cov pa oxygen thiab tiv thaiv kev ua kom tsis muaj zog ntxiv. Cov zaj duab xis no tuaj yeem ruaj khov txawm tias nyob hauv qhov chaw noo noo, yog li tiv thaiv cov saw hlau los ntawm kev xeb.

(II) Kev tiv thaiv corrosion ntawm cov khoom siv hlau tsis xeb sib txawv
Cov hlau tsis xeb muaj ntau yam khoom sib txawv, xws li 304, 316, 321, thiab lwm yam, thiab qhov tsis kam tiv thaiv corrosion ntawm txhua yam khoom sib txawv. 304 stainless hlau yog cov khoom siv feem ntau siv, nrog kev tiv thaiv corrosion zoo, haum rau feem ntau qhov chaw noo noo. 316 stainless hlau ua tau zoo dua hauv cov chaw muaj chloride ions, xws li cov chaw marine lossis cov chaw muaj ntsev. 321 stainless hlau muaj qhov tsis kam tiv thaiv oxidation kub zoo dua thiab haum rau cov chaw kub thiab noo noo.

II. Lub zog thiab kev tiv thaiv kev hnav ntawm cov saw hlau tsis xeb
Ntxiv rau qhov tiv taus xeb, cov saw hlau tsis xeb kuj muaj lub zog siab thiab tiv taus kev hnav zoo. Qhov no tso cai rau lawv kom tiv taus cov khoom loj thiab kev sib txhuam mus sij hawm ntev hauv cov chaw noo noo yam tsis yooj yim deforming lossis hnav tawm.

(Kuv) Lub zog siab
Lub zog ntawm cov saw hlau tsis xeb feem ntau yog los ntawm qhov nyuaj ntawm lawv cov khoom siv thiab cov thev naus laus zis ua haujlwm zoo. Piv txwv li, cov txheej txheem tsim cov khoom txias tuaj yeem ua rau ntau yam khoom ntawm cov saw hlau muaj lub zog thiab qhov nyuaj dua, yog li txhim kho lub zog tensile ntawm cov saw hlau. Qhov no ua rau cov saw hlau tsis xeb tuaj yeem tiv taus qhov nruj dua hauv qhov chaw noo noo thiab tsis yooj yim tawg.

(II) Hnav tsis kam
Qhov kev tiv thaiv kev hnav ntawm cov saw hlau stainless hlau feem ntau yog vim qhov tawv thiab du ntawm lawv cov nplaim. Ib qho nplaim siab tuaj yeem txo qhov kev sib txhuam thiab txo qhov kev hnav. Tsis tas li ntawd, cov saw hlau stainless hlau feem ntau raug kho qhov chaw thaum lub sijhawm tsim khoom, xws li kev txhuam lossis plating, kom txhim kho lawv qhov kev tiv thaiv kev hnav.

III. Kev siv cov saw hlau tsis xeb hauv cov chaw noo noo
Qhov ua kom tsis txhob xeb thiab muaj zog ntawm cov saw hlau tsis xeb ua rau lawv siv dav hauv ntau qhov chaw noo noo. Cov hauv qab no yog qee qhov chaw siv:

(I) Kev lag luam ua zaub mov
Hauv kev lag luam ua zaub mov, kev huv thiab kev huv yog qhov tseem ceeb heev. Cov saw hlau tsis xeb tsis yog tsuas yog tiv taus xeb xwb, tab sis kuj yooj yim ntxuav thiab tua kab mob, thiab ua tau raws li cov qauv kev huv ntawm zaub mov. Lawv siv dav hauv cov siv thauj khoom noj, cov kab ntxuav, cov khoom siv ntim khoom, thiab lwm yam. Piv txwv li, hauv cov kab ua nqaij, cov saw hlau tsis xeb tuaj yeem ua haujlwm tau ntev hauv qhov chaw noo thiab muaj cov tshuaj ntxuav tsis muaj xeb lossis ua rau zaub mov puas tsuaj.

(II) Kev lag luam tshuaj lom neeg
Ntau qhov chaw nyob hauv kev lag luam tshuaj lom neeg muaj cov tshuaj lom neeg heev, xws li cov kua qaub, alkalis, ntsev, thiab lwm yam. Cov saw hlau stainless tuaj yeem tiv taus kev yaig ntawm cov tshuaj no thiab tsim nyog rau kev xa thiab xa cov khoom siv tshuaj lom neeg. Piv txwv li, hauv lub cuab yeej sib xyaw ntawm lub tshuab tshuaj lom neeg, cov saw hlau stainless tuaj yeem ua haujlwm hauv qhov chaw noo noo thiab tshuaj lom neeg corrosive ntev, kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm cov khoom siv.

(III) Kev Tsim Kho Dej Hiav Txwv
Cov av noo siab thiab cov tshuaj tsuag ntsev hauv ib puag ncig marine ua rau cov khoom siv hlau xeb heev. Cov saw hlau stainless ua tau zoo hauv kev tsim kho marine thiab tsim nyog rau cov nkoj, cov khoom siv chaw nres nkoj, cov platforms offshore, thiab lwm yam. Piv txwv li, cov saw hlau stainless siv tau rau kev thauj khoom thiab tshem tawm ntawm cov chaw nres nkoj, thiab lawv tuaj yeem tswj tau qhov ua tau zoo txawm tias nyob hauv qab dej hiav txwv thiab cov tshuaj tsuag ntsev.

(IV) Kev Lag Luam Kho Dej
Cov saw hlau hauv cov chaw kho dej yuav tsum ua haujlwm hauv dej ntev, thiab cov saw hlau tsis xeb yog qhov kev xaiv zoo tshaj plaws. Lawv tsis yog tsuas yog tiv taus xeb xwb, tab sis kuj tseem tuaj yeem ua haujlwm hauv qab dej ntev, thiab tsim nyog rau cov khoom siv kho dej phwj tuaj, twj tso dej, cov tshuab lim dej, thiab lwm yam. Piv txwv li, hauv lub kaw lus xa cov sludge ntawm lub chaw kho dej phwj tuaj, cov saw hlau tsis xeb tuaj yeem tiv taus kev yaig ntawm cov tshuaj lom neeg thiab cov kab mob me me hauv cov dej phwj tuaj, ua kom ntseeg tau tias lub kaw lus ua haujlwm ruaj khov.

IV. Kev saib xyuas cov saw hlau tsis xeb hauv cov chaw noo noo
Txawm hais tias cov saw hlau tsis xeb muaj kev tiv thaiv corrosion zoo heev thiab muaj zog, lawv tseem xav tau kev saib xyuas kom zoo hauv cov chaw noo noo kom ntev lawv lub neej kev pabcuam thiab tswj kev ua tau zoo

(i) Kev ntxuav tas li
Nyob rau hauv ib puag ncig uas muaj av noo, qhov chaw ntawm cov saw hlau stainless hlau yuav muaj dej noo, plua plav thiab av qias neeg. Kev ntxuav tas li tuaj yeem tshem tawm cov khoom tsis huv no thiab tiv thaiv lawv kom tsis txhob muaj tshuaj lom neeg cuam tshuam nrog qhov chaw ntawm cov saw hlau. Thaum ntxuav, koj tuaj yeem siv daim ntaub mos mos thiab cov tshuaj ntxuav tsis muaj zog, thiab tsis txhob siv cov tshuaj ntxuav uas muaj kua qaub, alkali lossis chlorine kom tsis txhob ua rau cov zaj duab xis chromium oxide ntawm qhov chaw ntawm cov saw hlau puas tsuaj.

(ii) Kev Siv Roj
Kev siv roj nplua nyeem kom zoo yuav txo tau qhov sib txhuam ntawm cov saw hlau thiab txo qhov hnav. Hauv qhov chaw noo noo, koj yuav tsum xaiv cov roj nplua nyeem uas muaj kev ua haujlwm zoo tiv thaiv dej, xws li cov roj nplua nyeem kub siab lossis cov roj nplua nyeem qib zaub mov. Thaum siv roj nplua nyeem, xyuas kom tseeb tias txhua qhov ntawm cov saw hlau tau coated nrog roj nplua nyeem kom tsis txhob poob roj nplua nyeem.

(iii) Kev tshuaj xyuas thiab kev hloov pauv
Tshawb xyuas seb cov saw hlau tsis xeb puas thiab puas tsuaj tas li thiab hloov cov khoom puas tsuaj raws sijhawm. Thaum kuaj xyuas, xyuam xim rau qhov hnav ntawm cov koob, cov menyuam, cov phaj saw thiab lwm yam khoom ntawm cov saw, nrog rau qhov nruj ntawm cov saw. Yog tias pom tias cov saw hlau puas lossis puas lawm, yuav tsum hloov nws raws sijhawm kom ntseeg tau tias cov khoom siv ua haujlwm zoo.

V. Xaus Lus
Cov saw hlau tsis xeb ua tau zoo hauv qhov chaw noo noo thiab muaj kev tiv thaiv xeb zoo heev, muaj zog heev thiab tiv thaiv kev hnav zoo. Lawv siv dav hauv kev lag luam xws li kev ua zaub mov, kev lag luam tshuaj lom neeg, kev tsim kho dej hiav txwv thiab kev kho dej, thiab tuaj yeem ua tau raws li qhov xav tau ntawm ntau yam kev ua haujlwm hnyav. Los ntawm kev saib xyuas kom zoo, xws li kev ntxuav tas li, kev roj nplua nyeem thiab kev tshuaj xyuas, lub neej ua haujlwm ntawm cov saw hlau tsis xeb tuaj yeem ntev dua kom ntseeg tau tias cov khoom siv ua haujlwm ruaj khov. Yog li ntawd, cov saw hlau tsis xeb yog cov khoom xa thiab xa khoom zoo tshaj plaws hauv qhov chaw noo noo thiab tsim nyog rau kev txhawb nqa dav dav thiab siv hauv ntau yam kev siv cuam tshuam.
