Puas saum npoo ntawm cov raj hlau stainless kuj xeb?

Dab tsi yog stainless hlau? Hauv ntau cov neeg to taub, "cov hlau tsis xeb" yog cov hlau uas tsis xeb, tab sis ntau tus neeg siv khoom ua xeb thaum xeb ua xeb (me ntsis) tshwm rau ntawm cov hlau tsis zoo. Yog vim li cas? Stainless hlau li qub muaj peev xwm tiv taus atmospheric oxidation-uas yog, stainless, tab sis kuj muaj lub peev xwm los txhim kho qhov nruab nrab uas muaj cov kua qaub, alkali, ntsev-uas yog, corrosion tiv thaiv. Txawm li cas los xij, qhov loj me ntawm nws txoj kev tiv thaiv kev hloov pauv nrog cov tshuaj lom neeg ntawm cov hlau nws tus kheej, lub xeev sib nrig, kev siv thiab hom kev tiv thaiv ib puag ncig. Xws li 304 steel yeeb nkab, nyob rau hauv qhov chaw qhuav thiab huv, nws muaj qhov zoo tshaj plaws los tiv thaiv xeb, tab sis thaum nws hloov mus rau thaj chaw hiav txwv, nws yuav ntev xeb hauv hiav txwv pos huab uas muaj ntsev ntau; thiab 316 steel yeeb nkab qhia tau zoo. Yog li ntawd, nws tsis yog txhua yam ntawm steel hlau, uas tiv taus xeb thiab xeb hauv ib puag ncig.
Stainless hlau valve ua raws li qhov tsis tshua muaj nyias, muaj zog, ntom thiab ruaj khov chromium-nplua nuj oxide zaj duab xis (tiv thaiv zaj duab xis) tsim rau nws saum npoo kom tiv thaiv qhov cuam tshuam thiab oxidation ntawm oxygen atoms los txuas ntxiv kom muaj peev xwm tiv thaiv xeb. Ib zaug vim qee qhov laj thawj, zaj yeeb yaj kiab no raug rhuav tshem mus tas li, cov pa atoms hauv huab cua lossis kua yuav txuas ntxiv mus rau sab hauv lossis cov hlau atoms hauv cov hlau yuav txuas ntxiv cais tawm, ua rau xoob hlau oxide, thiab cov hlau hlau yuav xeb tas li. Muaj ntau ntau yam kev puas tsuaj ntawm no zaj duab xis saum npoo av,
Muaj ob peb hom stainless hlau li qub uas muaj nyob rau hauv lub neej txhua hnub:
1. Sab saum npoo ntawm cov raj hlau txuas ua ke plua plav lossis lwm cov hlau txuas uas muaj lwm cov ntsiab lus hlau. Nyob rau hauv qhov huab cua noo, qhov hws ntawm qhov txuas thiab lub hlau tsis xeb txuas ob qho rau hauv lub roj teeb micro, uas pib pib kho cov tshuab hluav taws xob, cov yeeb yaj kiab tiv thaiv yuav puas, hu ua electrochemical corrosion.
2. Cov kua txiv cov organic (xws li melon thiab zaub, noodle kua zaub, hnoos qeev, thiab lwm yam) ua raws li cov nplaim hluav taws xob valve. Thaum muaj dej thiab oxygen, nws tsim cov organic acid, thiab cov organic acid yuav corrode hlau deg ntev ntev.
3. Sab saum npoo ntawm cov kav hlau tsis huv muaj cov kua qaub, alkali thiab ntsev dej cawv (xws li dej alkali thiab dej pob zeb sib xyaw rau ntawm phab ntsa kho kom zoo nkauj), ua rau xeb hauv zos.
4. Hauv cov huab cua tsis huv (xws li cov huab cua muaj ntau ntawm sulfides, carbon oxides, thiab nitrogen oxides), cov dej ua kua yuav ua rau sulfuric acid, nitric acid, thiab acetic acid kua cov pa, ua rau muaj tshuaj lom neeg xeb. Cov xwm txheej saum toj no tuaj yeem ua rau kev puas tsuaj ntawm stainless hlau saum npoo tiv thaiv zaj duab xis thiab ua rau xeb.
Yog li ntawd, txhawm rau kom ntseeg tau tias cov hlau saum npoo muaj qhov ci tas li thiab tsis xeb, peb pom zoo:
1. Lub ntsej muag ntawm cov khoom siv ntawm cov hlau tsis zoo nkauj yuav tsum tau muab ntxuav thiab txhuam kom tsis tu ncua kom tshem tau cov ntawv txuas thiab tshem tawm cov sab nraud uas ua rau kev hloov kho.

2. Lub 316 stainless hlau valve yuav tsum siv rau hauv thaj chaw dej hiav txwv. Cov ntaub ntawv 316 tuaj yeem tiv thaiv seawater corrosion.

3. Cov tshuaj lom neeg muaj pes tsawg leeg ntawm qee cov kav hlau stainless ntawm cov lag luam tsis tuaj yeem ua tau raws li cov qauv kev sib tw hauv tebchaws, thiab tsis tuaj yeem ua tau raws li cov cai ntawm 304 cov ntaub ntawv. Yog li ntawd, nws tseem yuav ua rau xeb, uas xav kom cov neeg siv yuav tsum ua tib zoo xaiv cov khoom lag luam los ntawm cov tuam txhab muaj npe zoo. Kev tsim kho thiab kev tsim kho cov ntsiab lus ntawm kev saib xyuas txhawm rau txhawm rau tiv thaiv qhov khawb thiab nplaum ntawm kev ua qias tuaj thaum lub sijhawm tsim kho, stainless hlau li qub tau tsim nyob rau hauv lub xeev zaj yeeb yaj kiab. Txawm li cas los xij, nrog kev txuas ntxiv ntawm lub sijhawm, qhov seem ntawm qhov muab tshuaj daws tau ua raws li kev siv lub sijhawm ntawm zaj duab xis. Tom qab hle zaj duab xis tom qab tsim, saum npoo yuav tsum tau ntxuav, thiab cov cuab yeej tshwj xeeb stainless hlau yuav tsum tau siv. Thaum tu cov cuab yeej nrog cov hlau dav dav, nws yuav tsum tau ntxuav kom huv si txhawm rau tiv thaiv kom tsis txhob muaj cov nplaum ntawm cov hlau tuaj. Cov. Kev saib xyuas yuav tsum tau saib xyuas kom tsis txhob tso cov tshuaj lom neeg lub zog loj thiab lub pob zeb ua kom zoo nkauj rau cov tshuaj kom hu rau cov hlau tsis huv. Yog tias lawv nyob rau hauv kev sib cuag, lawv yuav tsum tau ntxuav tam sim ntawd. Tom qab kev tsim kho tiav, siv cov tshuaj ntxuav tes tsis huv thiab dej kom ntxuav cov cement, ya tshauv, thiab lwm yam txuas nrog rau saum npoo.

Hauv txoj kev xaus, stainless hlau li qub yuav tsis muaj xeb-pov thawj, thiab tseem yuav xeb hauv qee yam. Peb yuav tsum nruab, tswj xyuas, thiab kho cov kav hlau stainless hauv qhov nruj raws li qhov yuav tsum tau ua, thiab sim tswj qhov tshwm sim ntawm xeb ntawm stainless hlau li qub hauv qee yam.
