Thaum lub sij hawm tsim thiab tsim cov tshuab ntim khoom, xaiv cov khoom siv ncaj qha cuam tshuam rau cov cuab yeej kev ua tau zoo, lub neej ntev, thiab kev siv tau. Cov ntaub ntawv tsim nyog tsis yog tsuas yog txhim kho lub tshuab kev ntseeg siab xwb tab sis kuj txo cov nqi tu, ua kom cov txheej txheem tsim tau zoo thiab nyab xeeb. Yog li, kev xaiv cov khoom siv rau lub tshuab ntim khoom yuav tsum xav txog ntau yam, suav nrog kev tiv thaiv corrosion, lub zog, hnav tsis kam, kev nyiam huv, thiab tus nqi -kev ua tau zoo.
Ua ntej, kev tiv thaiv corrosion yog qhov tseem ceeb hauv kev xaiv cov khoom ntim khoom. Vim tias ntau cov khoom ntim khoom (xws li cov khoom noj, tshuaj, lossis cov khoom siv tshuaj) tuaj yeem muaj cov khoom corrosive, cov khoom siv sib txuas yuav tsum tau tsim los ntawm corrosion-cov ntaub ntawv uas tsis muaj zog xws li stainless hlau (tshwj xeeb yog qib 304 lossis 316L), engineering plastics (xws li polytetrafluoroethylene (PTFE)}}plated steel {-. Cov ntaub ntawv no muaj txiaj ntsig zoo tiv thaiv qhov chaw corrosive xws li acids, alkalis, thiab ntsev tsuag, ua kom cov cuab yeej siv lub neej ntev.
Thib ob, txhua yam muaj zog thiab hnav tsis kam cuam tshuam ncaj qha rau cov cuab yeej ruaj khov thiab kav ntev. Piv txwv li, lub zog, bearings, thiab kis tau tus mob feem ntau yog ua los ntawm high-lub zog alloy steel los yog tshav kub-kho cov pa roj carbon steel kom lawv tiv taus deformation thiab hnav nyob rau hauv siab loads. Rau cov khoom uas muaj kev sib txhuam tsis tu ncua, xws li conveyor siv rollers lossis seals, cov ntaub ntawv polymer (xws li polyurethane lossis nylon) tuaj yeem siv los txo qis hnav thiab txhim kho kev ua haujlwm zoo.
Tsis tas li ntawd, kev nyiam huv huv yog qhov tseem ceeb tshwj xeeb hauv cov khoom noj thiab tshuaj ntim tshuab. Cov khoom siv rau cov khoom siv no yuav tsum ua raws li FDA (US Food and Drug Administration) lossis EU cov qauv, kom ntseeg tau tias lawv tsis yog - tshuaj lom, tsis yog - paug, thiab yooj yim los ntxuav. Stainless hlau yog cov khoom siv zoo tshaj plaws rau cov ntawv thov no vim nws qhov chaw du, corrosion kuj, thiab siab -kub tsis kam. Cov txheej txheem vuam yuav tsum tau ceev faj kom tsis txhob muaj cov av seem nyob hauv cov ces kaum.
Thaum kawg, tus nqi -kev ua tau zoo kuj yog qhov tseem ceeb hauv kev xaiv cov khoom siv. Thaum siab - cov ntaub ntawv kawg (xws li cov khoom siv tshwj xeeb lossis cov yas tuaj txawv teb chaws) muaj kev ua tau zoo, lawv tuaj ntawm tus nqi siab dua, uas yuav tsum tau ntsuas raws li qhov xav tau tiag tiag. Piv txwv li, tsis yog- cov khoom tseem ceeb tuaj yeem siv tus nqi ntau dua -cov pa roj carbon steel lossis cov qauv yas, txo cov nqi tag nrho thaum ua kom muaj kev ua haujlwm.
Hauv cov ntsiab lus, kev xaiv cov khoom siv rau lub tshuab ntim khoom yuav tsum ua raws li cov txheej txheem tshwj xeeb, ntsuas kev tiv thaiv corrosion, lub zog, qauv kev nyiam huv, thiab tus nqi -kev ua tau zoo los xyuas kom muaj kev ua haujlwm tau zoo thiab ntev - kev ntseeg tau. Kev sib xyaw ua ke ntawm cov khoom muaj txiaj ntsig thiab sib npaug tsis yog tsuas yog txhim kho kev ua haujlwm ntawm lub tshuab, tab sis kuj tseem tsim cov nqi ntau dua rau cov tuam txhab.
