Yuav ua li cas yog PTFE rhaub siv nyob rau hauv kub DI dej yaug Tank rau kev kho mob Device Cleaning?

Kev phais thiab cov cuab yeej siv tau raug ntxuav hauv dej kub deionised tom qab machining. Txhua qhov chaw uas sib cuag nrog cov dej no, thiab tshwj xeeb tshaj yog lub rhaub dej, yuav tsum tsis txhob tso ib yam dab tsi uas tuaj yeem nyob rau saum npoo ntawm lub cuab yeej, ua rau muaj kev cuam tshuam rau tus neeg mob lossis cuam tshuam rau kev tsis muaj menyuam. Rau PTFE rhaub siv nyob rau hauv DI dej yaug cov cuab yeej siv kho mob, lub rhaub purity yog ib qho teeb meem ntawm tus neeg mob kev nyab xeeb thiab kev ua raws cai.

Kub Deionised Dej Yaug rau Kev Kho Mob Khoom Siv Khoom
Rau kev tu zaum kawg hauv kev tsim khoom siv kho mob, cov tshuab ntxhua khaub ncaws siv lub tshuab ntxhua khaub ncaws lossis cov twj tso kua mis tshwj xeeb nrog cov dej deionised (DI) siv. Cov tshuab no feem ntau ua haujlwm ntawm qhov kub thiab txias hauv thaj tsam ntawm 70℃txog 90℃kom nce cov pa phem tshem tawm, txhim kho kev ua haujlwm kom qhuav thiab txo qis microbiological kev pheej hmoo ua ntej kom tsis muaj menyuam.

Ntawm qhov kub thiab txias, qhov zoo ntawm cov dej yog qhov tseem ceeb tshaj plaws. Txawm tias muaj kuab paug ionic tuaj yeem tso rau saum npoo ntawm cov khoom siv tom qab ziab thiab tuaj yeem cuam tshuam nrog biocompatibility lossis kev ua kom tsis muaj menyuam tom qab.

Yog li, cov cua kub cua kub dhau los ua ib qho tseem ceeb ntawm kev sib cuag hauv ib puag ncig tu.

Qhov tseem ceeb ntawm cov khoom siv cua sov hauv High Purity Rinse Systems
Hlau Ions Contamination Risks Tshem Tawm
Cov kab ntau ntawm cov hlau, chromium lossis npib tsib xee tuaj yeem raug tso tawm thaum lub sijhawm nrog cov dej kub DI thiab cov khoom siv hluav taws xob ib txwm muaj (xws li hom stainless hlau). Txawm hais tias cov qib no yuav qis heev, kev sib sau ua ke dhau sijhawm lossis nyob rau hauv cov xwm txheej thermal cycling tuaj yeem ua rau pom kev kis kab mob.

Cov ions zoo li no tuaj yeem tso rau ntawm cov khoom siv phais lossis cov khoom siv cog qoob loo thaum tu. Hauv qee qhov xwm txheej, cov khoom seem no tuaj yeem ua rau muaj kev txhim kho hauv cheeb tsam, muaj xim tsis zoo, lossis txo qhov kev ua tau zoo ntawm biocompatibility nyob rau hauv ntev - daim ntawv thov cog qoob loo.

Lub PTFE lub rhaub dej DI dej yaug cov cuab yeej kho mob txo qis qhov teeb meem no los ntawm kev tshem tawm cov hlau los ntawm cov cua kub ntub dej. PTFE yog ib qho chemically inert barrier uas tsis emit ions, hais los yog extractables rau hauv cov txheej txheem dej.

PTFE rhaub yog ib txwm huv si thiab nws lav qhov kev huv ntawm cov dej yaug yog khaws cia thoob plaws hauv kev ua haujlwm tas mus li.

Thermal Effectiveness ntawm Tswj Kev Kho Mob Tu Txheej Txheem
Cov khoom siv nyab xeeb txwv nrog cov cua sov ruaj khov
DI dej yaug tso tsheb hlau luam feem ntau yog nyob rau hauv 70-90℃ntau yam, uas yog zoo nyob rau hauv lub nruam kev pab cuam kub muaj peev xwm ntawm PTFE (nyob ib ncig ntawm 110 degree). Qhov no muab cov npoo kev nyab xeeb rau lub sij hawm ntev thermal stability.

Typically, heaters are designed with conservative watt density values ​​(typically<=1.5 W/cm 2 ) to prevent localised overheating and to maintain consistent heat dispersion in the tank. Kev khiav dej num kom zoo yog tswj xyuas kom tsis txhob muaj qhov kub thiab txias stratification thiab muab kev tu zoo rau txhua qhov chaw ntawm qhov ntsuas.

Kub homogeneity yog qhov tseem ceeb tshwj xeeb hauv kev siv tshuab ntxhua khaub ncaws uas yuav tsum tau rov ua dua thiab siv tau raws li kev tswj hwm.

Regulatory Aspects of Medical Device Cleaning Systems
3.2.4 Ua raws li cov ntaub ntawv tiv tauj
Tag nrho cov ntaub ntawv nyob rau hauv kev sib cuag nrog cov txheej txheem kua siv rau zaum kawg tu nyob rau hauv kev tsim cov khoom siv kho mob yuav tsum ua raws li cov kev cai nruj. Cov no suav nrog FDA cov qauv kev cai xws li 21 CFR rau cov khoom siv hauv kev tsim thiab ua cov khoom siv kho mob.

Nyob rau hauv cov ntaub ntawv no purity ntawm cov txheej txheem yog tsis xaiv. Kev kis kab mob ntawm theem kawg yaug nrog txhua yam khoom siv tuaj yeem cuam tshuam rau cov txiaj ntsig kev lees paub thiab cov ntawv pov thawj ntaus ntawv.

PTFE cov cua sov muaj ntau heev vim lawv muaj qhov ruaj khov, tsis muaj zog, tsis yog- paug cov cua sov uas ua tau raws li cov txheej txheem kev cai.

Kev Txhim Kho Kev Ua Haujlwm rau Kev Tu Nruam Cov Txheej Txheem Rov Ua Haujlwm Thermal Cycling Stability
Cov cuab yeej siv kho mob tu tshuab yog feem ntau ua haujlwm tas li hauv cov xwm txheej tsim khoom. Cov ntaub ntawv siv hauv cov ntawv thov no yuav tsum muaj sijhawm ntev - tshuaj lom neeg thiab thermal stability kom tiv taus cov cua sov rov ua dua thiab raug rau DI dej.

PTFE yuav tsis degrade raws li cov xwm txheej no, thiab yuav muab kev ua haujlwm zoo ib yam yam tsis muaj kev pheej hmoo ntawm kev sib kis lossis degradation. Cov qhov chaw tso cua sov tau khaws cia rau hauv qhov system tsim kom txo qis hauv cheeb tsam overheating lossis qhuav raug xwm txheej.

Xaus: Cov Cuab Yeej Huv Huv rau Bio-Ua raws cov txiaj ntsig
PTFE cua sov yog qhov tseem ceeb hauv cov khoom siv kho mob ntxuav cov dej kub DI dej yaug tshuab. Cov cua sov no tiv thaiv cov hlau ion tso tawm thiab xyuas kom ruaj khov thermal ua haujlwm ntawm 70-90℃los pab khaws cia qhov kawg huv huv thiab biocompatibility ntawm cov cuab yeej phais thiab cov khoom siv cog qoob loo.

Cov dej uas siv rau qhov kawg yaug theem ntawm kev tsim khoom siv kho mob yuav tsum yog cov ntshiab li cov cuab yeej kho mob nws tus kheej. Cov xwm txheej no ib txwm hais nrog PTFE cua sov thev naus laus zis thiab lav kev tswj hwm kev nyab xeeb thiab kev nyab xeeb ntawm tus neeg mob los ntawm kev sib kis - tsis pub muaj kev tswj hwm thermal.
