Kev tswj hwm kev ua raws cai thiab cov ntaub ntawv rau Teflon (PTFE) cov khoom

Ua kom ntseeg tau tias kev ua raws cai thiab ua tiav cov ntaub ntawv rau Teflon (PTFE) cov khoom lag luam yog qhov tseem ceeb kom ua kom zoo tshaj plaws, kev nyab xeeb, thiab kev nkag mus rau hauv khw. Teflon, ua cov ntaub fluoropolymer, yog qhov nyuaj rau ntau txoj cai thiab cov lus pom zoo uas tswj hwm nws cov kev tsim khoom, kev siv, thiab kev tshaj tawm kev tsim nyog.

Ib qho ntawm cov txheej txheem tswj hwm tus lej tswj hwm cov khoom lag luam Teflon yog kev tso npe, kev tshuaj xyuas, kev tso cai, thiab txwv tsis pub siv tshuaj lom neeg (REACH) kev tswj hwm. Teflon thiab nws cov tshuaj tiv thaiv ua ntej yuav tsum tau sau npe zoo thiab tshuaj xyuas hauv qab REACH kom ua tau raws li European Union txoj cai tshuaj. Cov neeg tsim khoom thiab cov chaw muab khoom ntawm Teflon cov khoom lag luam yuav tsum tau ua raws li REACH cov ntawv sau npe thiab cov ntaub ntawv los qhia txog lawv txoj kev ua raws cai.

Ntxiv rau REACH, Teflon cov khoom lag luam tseem yuav muaj kev sib tw rau cov cai thiab cov cai tshwj xeeb rau kev lag luam lossis cov pob khoom uas lawv siv. Piv txwv li, nyob rau hauv cov zaub mov thiab dej haus kev lag luam, Teflon coatings thiab additives yuav tsum tau raws li qhov yuav tsum tau ntawm AmericaA Food and Drug Administration (FDA) rau cov pluas noj kov cov ntaub ntawv. Cov ntaub ntawv nthuav dav, xws li cov ntaub ntawv pov thawj, kev kuaj kev tsiv teb tsaws chaw, thiab cov lus tshaj tawm ua raws, yog qhov tseem ceeb los piav qhia txog kev ua raws li cov cai ntawm kev lag luam tshwj xeeb.

Tsis tas li ntawd, cov khoom siv Teflon siv rau hauv cov khoom siv kho mob, kev tsim tshuaj, lossis cov pob khoom kho mob sib txawv kuj tseem yuav xav ua raws li cov cai ntxiv, uas suav nrog AsmeskasA FDA cov cai tswj kev kho mob lossis European Medical Device Regulation (MDR). Cov ntaub ntawv ntxaws ntxaws, xws li kev tshawb fawb txog biocompatibility, kev ntsuam xyuas lub caij nyoog, thiab qhov tseeb ntawm lub tshuab tswj tau zoo tshaj plaws, yog qhov tseem ceeb los ua kom muaj qee yam kev tswj hwm kev ua raws li cov pob khoom touchy.

Cov ntaub ntawv tsim nyog thiab kev taug qab kuj tseem ceeb heev rau cov khoom muag Teflon. Cov neeg tsim khoom thiab cov neeg muab kev pabcuam yuav tsum khaws cov ntsiab lus tshwj xeeb ntawm cov txheej txheem tsim khoom, cov ntaub ntawv tsis huv, kev tswj xyuas zoo tshaj plaws, thiab cov ntaub ntawv tshwj xeeb. Cov ntaub ntawv no tej zaum yuav yog ib qho tseem ceeb nyob rau hauv lub sij hawm ntawm lub sij hawm ntawm ib qho khoom rov qab, yuav nug, los yog kev tswj xyuas los qhia txog kev ncaj ncees thiab zoo tshaj plaws ntawm cov khoom Teflon.
