Hauv chav ua haujlwm, chaw kho hniav, thiab cov khoom siv kho mob tsim cov chav huv huv, PTFE high-temperature daim kab xev
Ua tsaug rau nws cov tshuaj inertness, tsis tshua muaj kev sib txhuam, thiab thermal stability, PTFE yog ib qho ntawm feem ntau siv fluoropolymer hauv kev kho mob. Tab sis ua li cas koj thiaj paub tias PTFE daim kab xev twg tsim nyog rau kev siv kho mob twg? Cov lus teb yog nyob ntawm hom kev sib cuag (tus neeg mob hu ncaj qha vs. indirect), cov qauv kev tswj hwm (FDA, ISO 10993), thiab daim ntawv thov ib puag ncig.
Aokai PTFE tau muab PTFE cov ntaub ntawv rau kev kho mob rau xyoo. Tsab ntawv xov xwm no qhia txog cov ntawv thov kev kho mob los ntawm kev sib cuag, piav qhia txog cov qauv kev cai tseem ceeb, thiab muab cov kev taw qhia txog kev xaiv.

Regulatory Standards for Medical-Qib PTFE
1. FDA 21 CFR 177.1550 - Kev ua raws cai hauv paus
FDA 21 CFR 177.1550 yog lub hauv paus ntawm US Food and Drug Administration txoj cai rau fluoropolymer resins. Kev ua raws cai ua kom cov khoom siv PTFE muaj kev nyab xeeb rau kev rov siv dua hauv kev sib cuag nrog zaub mov - thiab los ntawm kev txuas ntxiv, yog ib qho qauv siv rau kev kho mob qib PTFE.
Qhov txawv tseem ceeb: FDA tsis pom zoo cov ntaub ntawv raw; nws pom zoo cov cuab yeej kho mob tiav. Thaum tus neeg muag khoom hais tias PTFE yog 'FDA pom zoo,' lawv feem ntau txhais tau hais tias cov khoom ua raws li 21 CFR 177.1550 - uas yog ib qho kev sib cuag zaub mov-. Rau cov khoom siv kho mob, qhov kev pom zoo zaum kawg yog nyob ntawm lub chaw tsim khoom siv cov khoom xa mus rau FDA.
2. ISO 10993 - Kev Ntsuas Biocompatibility
Rau daim ntawv thov kev sib cuag ncaj qha rau tus neeg mob, PTFE yuav tsum tau sim rau ISO 10993 series:
Kuaj
