Tuubada PTFE ee Siman loo Isticmaalo ee Daawada | Tuubooyinka ay FDA ansixisay

Codsiyada Tuubada PTFE ee Smooth Bore ee Warshadaha Daawooyinka

Waaxda dawooyinka, waddo kasta oo dareere ah waa inay buuxisaa baahi aan gorgortan laga geli karin: nadiifnimo buuxda.

Marka injineeradu ay raadiyaan "tuubada PTFE ee loo isticmaalo daawada", shaandhada ugu horreysa ee ay mari karaan waa "oo ay FDA ogolaatay"Tuubada PTFE ee siman".

Shirkaddayadu waxay macaamiisha siinaysay xalal lagu kalsoonaan karo muddo labaatan sano ah. Annagoo adeegsanayna agab PTFE ah oo 100% bikro ah, waxaan soo saarnaa tuubooyin PTFE ah oo siman oo aan kaliya buuxinayn FDA 21 CFR 177.1550 laakiin sidoo kale bixiya waxqabad heer sare ah oo qiimo ahaan ixtiraamaya miisaaniyadaha raasamaalka ee maanta oo adag.

Maxay warshadaha dawooyinka u doortaanPTFE?

Polytetrafluoroethylene waa kiimiko ahaan aan ku habboonayn wax kasta oo dareere ah, aashito, saldhig, iyo walxo daawo oo firfircoon oo laga helo wax soo saarka daawada.

Si ka duwan beddelka elastomeric ama silicone, PTFE ma bararto, ma dildilaacdo, ama ma daadiso balaastikada marka la kulmo kiimikooyinka CIP/SIP ee daran sida sodium hypochlorite ama saabuunta pH-ga sare leh. Dusha sare ee gudaha ee aadka u siman (Ra ≤ 0.8 µm) waxay sii yareysaa isku-dhejinta badeecada iyo sameynta biofilm, iyadoo hubineysa daahirnimada dufcad-ilaa-dufcad waxayna si weyn u yareyneysaa waqtiga xaqiijinta ee hab-raacyada nadiifinta.

Daraasad Kiis:

Khadka Buuxinta Tallaalka Yurub

Bayoolajiyad heer dhexe ah oo ku taal Jarmalka ayaa lumisay ilaa 2% tallaalka mRNA ee qiimaha sare leh nuugista darbiga gudaha ee qallafsan ee khadadka wareejinta silikoon ee tidcan. Ka dib markii loo beddelay isku-xidhka tuubada PTFE ee FDA-shahaadaysan, khasaaraha badeecaddu wuxuu hoos uga dhacay 0.3% wareegyada xaqiijinta nadiifintana waxaa laga soo gaabiyey siddeed saacadood ilaa afar. Macaamiishu waxay soo sheegeen keyd sanadle ah oo ah €450,000 - oo ku filan in lagu caddeeyo dib-u-hagaajinta xariiqda buuxda rubuc gudaheed.

Daraasad Kiis: Warshadda Dahaarka Kiniiniga ee Hormoonka Mareykanka

CDMO oo fadhigeedu yahay Florida wuxuu u baahday khad wareejin dabacsan oo u adkaysan kara labada ganaax ee dahaarka ku salaysan acetone iyo wareegyada SIP ee 121 °C. Tuubooyinka tartanka leh ee leh daboolka fluoroelastomer ayaa fashilmay ka dib saddex bilood oo wareeg ah oo kuleyl ah. Tuubooyinkayaga siman ee PTFE, oo lagu tidcay bir aan miridh lahayn oo 316L ah si looga hortago qalooca, hadda waxay diiwaan galiyeen 24 bilood oo adeeg joogto ah iyada oo aan lumin sumcadda. Xaruntu waxay ku gudubtay baaritaan lama filaan ah oo FDA ah iyada oo aan wax indho-indhayn ah la xiriirin qaybaha marinnada dareeraha.

Gunaanad

Marka injineerada dawooyinka ay qeexaan "Tuubada PTFE ee siman ee dhalada ah"Waxay runtii codsanayaan saddex shay: halis wasakh ah oo aan lahayn, aqbalaad sharci oo aan kala go 'lahayn, iyo mas'uuliyad maaliyadeed. Labaatan sano oo xog ah oo goobta ah ayaa muujinaya in tuubadayada PTFE ee bikrada ah ee 100% bikrada ah ay bixiso saddexda - taasoo caddaynaysa in daahirnimada iyo dhaqaaluhu ay ku wada noolaan karaan isla qalabka.
