Lub hauv paus rau phau ntawv
Stainless hlau tau dav siv hauv ntau qhov kev lag luam vim nws txoj kev tiv thaiv zoo heev, lub zog, thiab kev ua kom zoo nkauj. Txawm li cas los xij, txawm tias stainless hlau tsis yog kiag li immune rau corrosion nyob rau qee yam. Passivation yog cov txheej txheem tseem ceeb uas tuaj yeem txhim kho txoj kev corrosion tsis kam ntawm stainless hlau, thiab stainless hlau passivation paste yog cov khoom siv uas siv rau lub hom phiaj no.
Nkag siab passivation
Passivation yog cov txheej txheem tshuaj lom neeg uas tshwm sim rau ntawm cov hlau, hauv cov hlau no, stainless hlau. Thaum stainless hlau yog nthuav tawm qee qhov chaw ib puag ncig, tshuaj lom neeg nyias, nyias, pom tsis tau, thiab cov txheej txheem oxide heev rau nws saum npoo. Qhov oxide txheej yog lub npe hu ua lub passive zaj duab xis. Cov yeeb yaj kiab passive ua raws li kev tiv thaiv kev tiv thaiv, tiv thaiv kev tiv thaiv kev ntxiv ntawm oxidation thiab corrosion ntawm cov hlau hauv qab. Nws yog ib qho tseem ceeb kom nco ntsoov tias cov yeeb yaj kiab passive yog kev kho tus kheej rau qee yam. Yog tias qhov saum npoo uas khawb lossis puas, cov hlau hauv qab tuaj yeem hnov mob nrog oxygen nyob hauv ib puag ncig kom hloov zaj duab xis passive.
Dab tsi yog stainless hlau passive muab tshuaj txhuam?
Stainless hlau passivation paste yog cov tsim cov tshuaj chemulated tsim tshwj xeeb los pab txhawb cov txheej txheem passive ntawm stainless hlau qhov chaw. Nws yog cov tshuaj txhuam zoo li cov khoom, uas ua rau nws yooj yim rau kev thov rau ntau cov qauv hlau, suav nrog cov uas muaj cov nyom ua rau thaj chaw. Tus muab tshuaj txhuam muaj cov tshuaj sib xyaw ua ke uas tau raug xaiv los txhawb qhov kev tsim ntawm lub nkuaj ruaj khov thiab niaj hnub ua si ntawm cov hlau stainless.
Cov Cheebtsam ntawm Stainless Hlau Passivation
Cov neeg sawv cev acidic: Ntau passive pastes muaj acidic Cheebtsam xws li nitric acid, citricor acid, lossis phosphoric acid. Cov kua qaub no ua lub luag haujlwm tseem ceeb hauv cov txheej txheem passivation.
Inhibitors: qee cov passes uas passes ua kom muaj inibitors. Cov no yog cov tshuaj lom neeg uas qeeb qeeb ntawm tus nqi ntawm corrosion lossis sab kev tshwm sim thaum lub sij hawm passivation txheej txheem. Inhibitors tuaj yeem pab kom ntseeg tau tias qhov kev sib tw hla dhau los hauv kev tswj hwm, tiv thaiv kev tiv thaiv ntau ntawm stainless - hlau nto.
Thickeners: muab cov khoom passivation nws muab tshuaj txhuam zoo li ib txwm zoo li ib txwm, thickeners tau ntxiv. Cov tuab tuab xws li cov tshuaj yeeb zoo xws li Bentonite av nplaum lossis qee cov polymers. Cov tuab yuav pab cov tshuaj txhuam kom ua raws li thaj chaw uas tsis muaj ntsej muag ntsug, tshwj xeeb yog nyob rau thaj chaw ntsug, thiab tiv thaiv nws los ntawm kev nqus lossis khiav tawm ua ntej cov kev sib tw dhau los ua tiav.
Cov ntawv thov ntawm stainless hlau passivation muab tshuaj txhuam
Kev lag luam thiab dej haus kev lag luam: Stainless hlau yog qhov chaw nyob hauv cov zaub mov thiab dej haus rau cov khoom siv xws li tso tsheb hlau luam, raj dej, thiab ua tshuab. Hla kev siv cov passi passe yog qhov tseem ceeb kom ntseeg tau tias cov kab hlau stainless hlau tsis muaj cov kab mob tsis huv thiab muaj kev ua kom haum corrosion. Qhov no yog qhov tseem ceeb li ib qho kev xeb lossis paug yuav cuam tshuam qhov ua tau zoo thiab kev nyab xeeb ntawm cov zaub mov thiab dej haus ua tiav. Piv txwv li, nyob rau hauv ib tug brewery, lub stainless hlau fermentation tso tsheb hlau luam los tiv thaiv kev tsim cov xeb lossis lwm yam kev paug uas tuaj yeem hloov cov saj thiab zoo ntawm npias.
Kev teb kho mob: Stainless hlau yog ib qho khoom siv hauv cov cuab yeej kho mob, xws li kev phais cov cuab yeej thiab kev pom. Hla ntawm cov cuab yeej siv uas siv passivation paste pab txhim kho lawv cov biocompatibility thiab corrosion tsis kam. Ib qho kev ua yeeb yaj kiab ruaj khov nyob rau saum npoo ntawm kev phais ntsuas lossis cog hniav txo txoj kev pheej hmoo ntawm cov hlau ions rau hauv lub cev, uas tuaj yeem ua rau muaj kev cuam tshuam. Tsis tas li ntawd, kev txhim kho corrosion tsis ntseeg tau ntev ntev ntawm cov cuab yeej hauv lub cev.
Aerospace kev lag luam: hauv kev lag luam AERPACACE, qhov twg cov khoom siv feem ntau raug rau cov chaw hnyav, cov hlau stainless tsis muaj kev tiv thaiv corrosion zoo heev. Thaub passivation yog siv los kho qhov chaw xws li lub dav hlau cav cov khoom siv, tsaws iav qhov chaw, thiab cov txheej txheem txheej txheem. Daim ntawv thov ntawm passivation paste pab tiv thaiv cov ntu ntawm corrosion, uas tuaj yeem ua rau muaj kev nyab xeeb thiab ua haujlwm ntawm lub dav hlau.
Cov ntawv thov architectural: Stainless hlau tau dav siv hauv architecture rau cov ntsiab lus zoo nkauj, tes ua, thiab facades. Hla kev siv passivation paste tuaj yeem txhim kho cov tsos thiab kev ruaj khov ntawm cov qauv no. Los ntawm kev sib sau ua yeeb yaj kiab tiv thaiv, cov stainless hlau chaw tsis tshua muaj xeb stills lossis discoloration, tswj lawv cov kev thov kom zoo nkauj dua sijhawm.
Cov txheej txheem ntawm kev siv Stainless Hlau Passivation
Npaj ua ntej: ua ntej thov cov passe passe, lub stainless hlau nto yuav tsum tau huv huv. Qhov no cuam tshuam nrog kev tshem tawm ib qho av, roj, roj, lossis lwm yam paug. Degaging cov neeg sawv cev lossis cov kuab tshuaj tuaj yeem siv los ntxuav cov nplaim dej. Cov qauv siv tshuab xws li cov tsis huv tawg lossis xaim txhuam hniav kuj tseem siv tau los tshem tawm cov kab mob hnyav me ntsis, uas tuaj yeem txhim kho cov nplaum ntawm passivation paste.
Lub sijhawm dhau los: Tom qab daim ntawv thov muab tso rau sab laug rau saum npoo rau lub sijhawm tshwj xeeb los tso cai rau cov tshuaj lom neeg. Lub sijhawm kev tawm tsam tuaj yeem sib txawv nyob ntawm qhov xwm txheej xws li cov hom stainless hlau, cov lus sib xyaw ntawm passivation paste, thiab qhov ntsuas kub. Feem ntau, lub sijhawm tshuaj tiv thaiv nyob ntawm 15 feeb txog ob peb teev. Nyob rau lub sijhawm no, cov tshuaj hauv cov tshuaj txhuam tawm nrog cov hlau stainless sab saum toj los ua zaj duab xis uas passive.
