Cov Khoom Siv-Qib Sib Piv: 304 Stainless-Steel piv rau 316L Stainless-Steel Dishwasher Cua sov-Element thiab Thermocouple-Sheath Adaptability
Kev xaiv cov khoom-qib ncaj qha txiav txim siab lub tshuab ntxuav tais diav-cov khoom siv los tiv thaiv corrosion nyob rau hauv cov dej-zoo thiab cov tshuaj ntxuav tais diav-chemistry. Qhov sib txawv muaj nyob nruab nrab ntawm 304 stainless-steel thiab hloov kho 316L stainless-steel hais txog chloride-ion-resistance, anti-pitting-corrosion muaj peev xwm thiab scale-adhesion nyiam. Cov khoom-qib variation indirectly influences thermocouple ntev-lub sij hawm ntsuas-stability thiab tag nrho-system kev pab cuam-lub neej expectancy. Rational khoom-qib xaiv sib npaug cov khoom siv-tsim nqi, corrosion-resistance kev ua tau zoo thiab kub-tswj-loop kev ntseeg tau.
304-qib stainless-steel sawv cev rau cov khoom siv tseem ceeb rau cov tshuab ntxhua khaub ncaws ua cua sov-cov ntsiab lus. Nyob rau hauv nruab nrab-zoo-dej-qhov chaw tej yam kev mob nrog tsawg-chloride-ion cov ntsiab lus, 304 stainless-steel muab kev ruaj ntseg tshuaj-tiv taus kev ua tau zoo. Nto smoothness restrains ib nrab ntxhia-scale adhesion. Kev sib xyaw ua qauv-qib thermocouple cov rooj sib txoos nrog 304-cov ntaub qhwv ua kom txaus siab rau feem ntau tsev neeg-lub tshuab ntxuav tais diav ua haujlwm-qhov yuav tsum tau ua. Tus nqi-kev ua tau zoo ua rau 304-qib cov khoom siv dav dav hauv cov khoom siv tshuab ntxhua khaub ncaws-cov khoom siv dav dav.
316L low-carbon molybdenum-muaj stainless-steel muab kev tiv thaiv zoo tiv thaiv chloride-ion-triggered pitting corrosion. Cov dej uas muaj cov tshuaj chloride ions, ntxiv rau cov tshuaj ntxuav tais diav uas muaj chlorine-detergent, tsim cov corrosive ib puag ncig uas 304-qib cov khoom tsim pitting-corrosion maj mam. Molybdenum-alloying element nyob rau hauv 316L cov khoom suppresses pit-initiation probability heev. Cov khoom siv hluav taws xob cua sov lub cev thiab cov thermocouple tiv thaiv-sheaths tsim los ntawm 316L cov ntaub ntawv txhawb nqa lub sijhawm ntev ntawm cov tshuaj chloride-muaj ntxhua khaub ncaws-nruab nrab. Surface-condition stability tswj kom zoo ib yam ntawm cov cua sov-hloov efficiency thiab txo cov thermocouple-probe-pab kis ceev.
Cov khoom-qib sib txawv manifests nyob rau hauv thermocouple-system ntev-ntev-precision tuav. Corrosion-induced deg roughness accelerates composite-deposit tsub zuj zuj ntawm cov cua kub thiab cov thermocouple-sheath nto. Smooth corrosion-resistant nto qeeb scale-thiab-residue-build-up ceev. Tsawg-contaminated sensor-sheath nto khaws cov thermocouple ntsuas-qhov tseeb rau lub sijhawm ua haujlwm ntev dua. Cov khoom siv-qib kev hloov kho ua rau muaj txiaj ntsig tsis ncaj rau thermal-control-loop stability.
Cov ntaub ntawv sib piv ntawm cov khoom siv-kev ua tau zoo yog qhia hauv cov lus hauv qab no:
| Khoom Qib | Chloride-Ion Corrosion Resistance | Surface Anti-Deposit Performance | Lub Sijhawm Tshav Kub-Hloov Hloov Kho Lub Sijhawm Ntev | Thermocouple-Sheath Matching-Drift Rate | Hom Daim Ntawv Thov Scenario |
|---|---|---|---|---|---|
| 304 Stainless hlau | Txais tau rau cov dej uas tsis muaj chloride-ion | Kev ua tau zoo hauv paus | 93.2% tuav tom qab 2000 cycles | 4.7% rau 1000 teev ua haujlwm | General-spec cov tshuab ntxuav tais diav hauv tsev |
| 316L Stainless hlau | Zoo heev anti-pitting-corrosion muaj peev xwm | Superior anti-deposit khoom | 97.8% tuav tom qab 2000 cycles | 1.6% rau 1000 teev ua haujlwm | Cov tshuab ntxhua khaub ncaws ua lag luam, cov dej-chloride-ion zoo hauv cheeb tsam |
Accelerated-aging-lab-testing qhia tau hais tias 316L-qib cov khoom txo cov cua kub-txheej txheem corrosion-txog-tsis ua hauj lwm qhov tshwm sim los ntawm 71% thiab slows thermocouple precision-drift tus nqi tseem ceeb nyob rau hauv hnyav-dej-zoo tej yam kev mob.
Cov txheej txheem kev xaiv cov khoom siv tau xaiv cov khoom siv cua sov-cov khoom siv substrate thiab cov khoom siv thermocouple-sheath raws li cov txiaj ntsig kev soj ntsuam dej hauv zos, cov yam ntxwv ntawm cov tshuaj detergent-formula thiab daim ntawv thov lub tshuab ntxuav tais diav. Hierarchical cov ntaub ntawv-qib sib npaug sib npaug cov khoom siv-tus nqi nkag thiab kev ntseeg siab ua haujlwm ntev.
