PTFE vs MPTFE (Modified PTFE)

PTFEthiab TFM yog siv rau hauv cov kab hauv cov ntawv thov kev tiv thaiv corrosion - tshwj xeeb tshaj yog cov organic tebchaw, acids, thiab ntsev - nrog rau qhov kub thiab txias thiab siab purity daim ntaub ntawv.Lawv ob leeg pom tus cwj pwm tsis yog lo, thiab muaj ntau yam zoo sib xws ntawm kev siv kub.Txawm li cas los xij, muaj qhov sib txawv tseem ceeb ntawm lawv, uas yog vim TFM muab cov yam ntxwv zoo tshaj plaws ntawm PTFE thiab PFA.TFM yog cov khoom siv hauv qab ntawm kev xaiv thaum koj xav tau cov pa roj tsawg tsawg, lub neej qaug zog ntev dua, thiab ua kom zoo dua.

Hloov kho PTFE yog ib qho tshuaj hloov kho ntawm PTFE uas muaj peev xwm tshiab ntxiv rau cov khoom ntiag tug raws li cov khoom siv nkauj xwb PTFE.

Hloov kho PTFE muaj cov yam ntxwv tshiab lossis txhim kho dua li tus qauv PTFE:

Ib feem ntawm qhov chaw yog smoother, thiab tsis ntxeem tau - cov khoom nyob twj ywm huv si vim lawv tsis tshua muaj cov kab mob tsis tshua muaj micro-void cov ntsiab lus yields txhim kho permeation resistanceLonger flex lub neej tshaj PTFEIncreased stiffness & txhim kho creep resistanceHigher dielectric zog yields superior high-voltage rwb thaiv tsevFusible / Weldable (Siv Ntau yam kev siv cua sov vuam nrog lub siab nruab nrab) Piv txwv ntawm Cov Thawv & Cov Tubes tsim siv APT's Modified PTFE Fusing & Machining Processes

PTFE stands rau Polytetrafluoroethylene, ib tug fluorocarbon thermoplastic uas tau pom dav siv nyob rau hauv engineering daim ntaub ntawv thiab paub zoo tshaj plaws rau muaj qhov qis tshaj coefficient ntawm kev sib txhuam ntawm tej khoom.Nws tseem hu ua polymer, Dyneon TM, 1,1,2,2-tetraflouroethene los yog 1,1,2,2-tetraflouroethylene.

Raws li twb tau hais tseg lawm, PTFE yog ib qho ntawm cov tshuaj lom neeg tsis muaj zog tshaj plaws muaj (Chemical Resistance Chart).Nws muaj qhov ntsuas kub tsis tu ncua ntawm -200 ° C txog 250 ° C thiab tiv taus dej nqus.Tsis tas li ntawd, nws muaj tus cwj pwm los tiv thaiv cov nplaum uas tiv thaiv cov khoom tsim tawm, ua rau nws yooj yim heev rau CIP (Clean In Place).Qhov tseeb, muaj ntau qib ntawm PTFE uas tau pom zoo los ntawm FDA.

Hloov kho PTFEyog tshuaj hu ua polytetrafluoroethylene, thiab los ntawm lub npe lag luam Polyflon.Nws yog ib qho kev sib xyaw ua ke ntawm cov khoom ntawm PTFE thiab PFA (Perfluoroalkoxy), uas paub txog nws cov khoom zoo tshaj plaws.

Zoo li PTFE, TFM yog tshuaj inert thiab muaj qhov zoo sib xws rau kev siv qhov kub thiab txias, nrog rau qhov zoo sib xws rau kev nqus dej.Nws tseem khaws tau ntau yam ntawm PTFE cov yam ntxwv tsis-stick.

TFM kuj tseem muaj lub caij nplooj ntoos hlav siab dua me ntsis, tab sis pom zoo kom qaug zog zoo dua thiab ua rau muaj kev ntxhov siab zoo dua.Tsis tas li ntawd, nws yooj yim dua rau vuam dua li PTFE thiab hnyav dua.TFM kuj tseem tiv taus ob qho tib si embrittlement thiab kev laus.

Ib yam uas ua rau TFM tshwj xeeb yog qhov ceev ntawm cov qauv molecular.Qhov no ua rau muaj qhov txo qis ntawm cov pa permeation rau tib lub thickness ntawm cov khoom thaum piv rau PTFE.Cov yam ntxwv no tseem ceeb heev thaum siv nyob rau hauv ib puag ncig corrosive heev.Nrog nws cov qauv ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom qauv tsim qauv, TFM kuj tseem muaj cov txheej txheem smoother ntawm PTFE.Tsis tas li, zoo li PTFE, muaj ntau qib ntawm TFM uas tau pom zoo los ntawm FDA.
