Stainless hlau hip implant, tom qab tau electropolished mus rau ib tug atomically smooth, corrosion- tiv thaiv daim iav tiav, yuav tsum tau rinsed nyob rau hauv kub, ultrapure dej. Qhov dej yaug zaum kawg no yog txheej txheem ntub dej kawg ua ntej cog cog, ntim, thiab kom tsis muaj menyuam. Txhua yam hlau ion paug tau qhia thaum lub sijhawm no tuaj yeem tso rau ntawm qhov chaw pristine, tsim cov kab mob me me uas yuav dhau los ua qhov chaw pib rau kev xeb lossis tshuaj lom neeg ib zaug cog. Yog li ntawd purity kiag li raug kho raws li ib tug tsis yog -negotiable yuav tsum tau.
HauvPTFE rhaub cov khoom siv kho mob electropolishing yaugsystems, thermal tswj thiab tshuaj inertness yuav tsum tau khaws cia ib txhij nyob rau theem siab tshaj ntawm cov txheej txheem huv.
Lub luag haujlwm ntawm Rhaub Dej Dej hauv Electropolishing Kab
Lub hom phiaj ntawm qhov kawg yaug theem
Tom qab electropolishing, implants khaws cia:
Residual acid electrolytes
Dissolved hlau ntsev
Organic polishing los ntawm - khoom
Cov dej kub deionized yog siv rau:
Tshem tawm cov tshuaj residue sai sai
Txhawb kev ziab kom zoo ib yam
Tiv thaiv kom tsis txhob muaj dej pom ntawm qhov chaw precision
Yaug qhov kub thiab txias yog feem ntau khaws cia ntawm60-80 degree, ua kom nrawm dua evaporation thiab txo qhov nro qhov cuam tshuam uas tuaj yeem tawm cov cim.
Dej Purity Requirements
Cov tshuab ntxhua khaub ncaws feem ntau ua haujlwm siv dej nrog:
Resistivity mus txog18 MΩ·cm
Tsis tshua muaj tag nrho cov organic carbon (TOC)
nruj ionic contamination txwv
Nyob rau theem purity no, txawm tias cov kab mob sib kis tau ua rau muaj kev pheej hmoo loj heev.
PTFE Rhaub raws li Kev Tiv Thaiv Kab Mob -Qhov Chaw Kub Kub Dawb
Tshuaj thiab Ionic Inertness
PTFE immersion rhaub yog xaiv vim:
PTFE sheath yog chemically inert rau ultrapure dej
Tsis muaj hlau ions raug tso rau hauv da dej yaug
Residual trace acids los ntawm cov txheej txheem dej ntws tsis ua rau lub tshuab cua sov
Qhov no ua kom cov dej purity yog khaws cia thoob plaws hauv lub voj voog cua sov.
Lub PTFE rhaub yog qhov kawg, tsis pom tus neeg saib xyuas ntawm kev cog cov atomic cleanliness, ntxiv tsis muaj dab tsi tab sis sov so rau qhov kawg, da dej ntshiab.
Kev Tiv Thaiv Kev Tiv Thaiv Qhov Ntog
Tsis zoo li cov khoom cua sov hlau, PTFE sheathed heaters tiv thaiv:
Hlau los yog npib tsib xee ion leaching
Deg staining ntawm electropolished implants
Tsim cov chaw hauv cheeb tsam corrosion pib
Txawm tias cov kab hlau rhuav tshem tuaj yeem cuam tshuam ntev - lub sij hawm cog kev ua haujlwm, ua rau kev xaiv cov khoom tseem ceeb.
Kev xav txog kev nyiam huv thiab huv huv
Crevice-Kev tsim kho dawb
Kev kho mob yaug tshuab xav tau cov cua sov tsim nrog:
Smooth sab nrauv
Tsawg kawg geometric qhov chaw tuag
Drainable installation orientation
Cov yam ntxwv no txo qhov kev pheej hmoo ntawm:
Bacterial biofilm tsim
Particle tsub zuj zuj
Tshuaj residue khaws cia
Resistance rau Scale thiab Biofilm Tsim
PTFE tsis yog - cov yam ntxwv stick muab qhov zoo ntxiv:
Txo cov ntxhia nplai adhesion
Tsawg qhov kev pheej hmoo ntawm microbial colonization
Yooj yim validation tu cycles
Qhov no txhawb nqa ntev - lub sij hawm ruaj khov ntawm siab - purity yaug ua haujlwm.
Cov txheej txheem ruaj khov thiab kev ua kom qhuav
Uniform Heat Distribution
Cov cua sov ruaj khov muab los ntawm PTFE immersion systems kom ntseeg tau tias:
Qhov ntsuas kub sib npaug ntawm lub tank ntim
Predictable evaporation tus nqi ntawm implant nto
Txo qhov tshwm sim ntawm qhov chaw ziab kom qhuav
Kev Tiv Thaiv Ntawm Dej Spot Tsim
Cov dej ntws tuaj yeem ua raws li:
Micro-scale deg nto discontinuities
Muaj peev xwm corrosion nucleation qhov chaw
Tshuaj pleev ib ce tsis xws luag hauv implant- qib tiav
Cov cua sov tswj kom txo qis cov kev pheej hmoo no los ntawm kev txhawb nqa kev ua kom qhuav sai thiab zoo ib yam.
Validation thiab Qualification Requirements
Ntxuav thiab Passivation Validation
Ua ntej xa mus rau hauv cov chaw tsim khoom kho mob, cov tshuab cua sov yuav tsum tau ua:
Cov txheej txheem tu cov ntaub ntawv
Tshuaj passivation pov thawj
Kev kuaj kab mob seem
Qhov no ua kom ntseeg tau tias lub rhaub nws tus kheej tsis qhia cov kab mob mus rau hauv cov txheej txheem validated kwj.
Kev txiav txim siab ua raws cai
Cov khoom siv kho mob tsim ib puag ncig feem ntau xav tau:
Traceable ntaub ntawv pov thawj
Txheej txheem validation cov ntaub ntawv
Ua raws li ISO cov qauv kev tsim khoom huv si
Cov cua sov ua ib feem ntawm cov cuab yeej siv tau siv tau, tsis yog cov khoom siv ib leeg.
System-Level Integration
Tank Design Compatibility
PTFE heaters feem ntau yog muab tso rau hauv:
Stainless hlau yaug tank
Recirculating pom loops
Ultrapure dej faib tshuab
Qhov system tsim kom ntseeg tau tias:
Nruam filtration ntawm cov dej yaug
ruaj khov kho qhov kub thiab txias
Tsawg ntws cuam tshuam nyob ib ncig ntawm implants
Xaus
Lub PTFE immersion rhaub yog ib qho tseem ceeb thiab tsis muaj kev cuam tshuam nyob rau hauv qhov kawg yaug theem ntawm cov cuab yeej kho mob electropolishing. Nws cov tshuaj inertness thiab xoom hlau ion tso tawm kom ntseeg tau tias ultrapure dej tswj nws txoj kev ncaj ncees thaum xa cov thermal zog yuav tsum tau ceev, qhov chaw -dawb qhuav ntawm siab - tus nqi cog.
HauvPTFE rhaub cov khoom siv kho mob electropolishing yaugdaim ntaub ntawv, lub rhaub dej purity yog txuas ncaj qha rau cov khoom ruaj ntseg thiab ntev -lub sij hawm biocompatibility.
Thaum kawg, kev nyab xeeb ntawm tus neeg mob tau ntau xyoo tom qab cog qoob loo yog cuam tshuam los ntawm microscopic purity ntawm cov dej kub yaug zaum kawg, qhia txog qhov kev ncaj ncees ntawm ib qho khoom siv cua sov ua rau muaj kev ntseeg siab ntawm lub neej - cov cuab yeej kho mob tseem ceeb.
