1. Cov kev txhawj xeeb tseem ceeb hauv kev lag luam tshwj xeeb
Cov tshuaj tsis huv:
Cov xeb xeb (patina) tuaj yeem tso cov lus, pheej hmooCov khoom tsis huvHauv ib puag ncig tsis muaj menyuam (piv txwv li, zaub mov noj, chaw muag tshuaj).
Hlau oxide plua plavyog tsis tsim nyog hauv cov chav huv lossis cov chaw noj zaub mov.
Corrosion Kuj txwv:
Hos lub patina tiv taus atmospheric corrosion, nwstsis muaj txheej txheem passiveNtawm stainless hlau, ua rau nws muaj kev yooj yim rau:
Tshuaj Lom Zem(acids, tshuaj tua kab mob, ntxuav cov neeg sawv cev).
Ya raws-nplua nuj / tu zej zog(xws li, cov chaw ntxuav)).
2. Kev tswj hwm & cov teeb meem kev nyiam huv
Kev Lag Luam Khoom Noj (FDA / EC1935):
Yuav tsum tauCov tsis muaj-ntxeem tau(xws li, stainless hlau 316L).
Weathering hlau lub voj voog saum lub harbors cov kab mob thiab ua kom cov dej khov huv.
Khoom Siv Kho Mob (ISO 13485):
Xav taubiocompatibilitythiab corrosion tsis kam mus rau lub cev ntawm lub cev / sterilants (piv txwv li, autoclaving).
3. Lwm txoj hauv kev rau kev lag luam tshwj xeeb
| Qhov toob kas | Cov khoom nyiam | Qhov zoo tshaj A423 |
|---|---|---|
| Kev Ua Noj | Stainless hlau (304 / 316L) | Tsis-lom, yooj yim huv si, pov thawj. |
| Cov Khoom Siv Kho Mob | Titanium lossis 316L stainless | Biocompible, withstands rov ua kom tsis muaj menyuam. |
| Kev Siv Tshuaj | Fiberglass-txhawb cov plastics | Tsis muaj zog rau corrosion los ntawm acids / tshuaj ntxuav. |
4. Tshwj xeeb cov ntaub ntawv uas A423 tej zaum yuav siv
Cov Qauv Hu Cov Qauv:
Kev kos npe sab nraudlossisTxhawb Cov Kab TawHauv cov chaw (yog cais los ntawm kev tu cev ntawm kev huv).
Yuav tsum yogcoated / sealedTxhawm rau tiv thaiv xeb cov hmoov av (piv txwv li, lub tsev noj mov ua noj ua ke vov).
Tag
A423 Huab Cua Hlau yogTsis tsim nyog rau kev siv ncaj qhaHauv cov ntaub ntawv / cov ntawv thov kev kho mob vim kev tiv thaiv kev pheej hmoo thiab tsis tshua corrosion tsis kam. Xaiv RauStainless hlau, Titanium, lossis Coated CompositesHloov chaw. Rau cov luag haujlwm (piv txwv li, lub tsev thav duab), xyuas kom meejkev rho tawm los ntawm cov chaw rhiab.
