I-PTFE vs MPTFE (i-PTFE elungisiweyo)

PTFEkunye ne-TFM zisetyenziselwa ukuvuthela kwizicelo zokumelana nokugqwala okugqithisileyo - ngokukodwa i-organic compounds, i-acids, kunye neetyuwa - kunye nobushushu obuphezulu kunye nezicelo zokucoceka okuphezulu.Bobabini babonisa ukuziphatha okungabambekiyo, kwaye banoluhlu olubanzi olufanayo lobushushu bokusebenzisa.Nangona kunjalo, kukho umahluko omkhulu phakathi kwabo, kuba i-TFM idibanisa ezona mpawu zibalaseleyo zazo zombini i-PTFE kunye ne-PFA.I-TFM yeyona nto ikhethwayo xa ufuna irhasi ephantsi kakhulu, ubomi obude bokudinwa, kunye nokugqitywa komphezulu ogudileyo.

I-PTFE elungisiweyo yinguqulelo eguqulwe ngokwekhemikhali ye-PTFE enesakhono ezitsha ukongeza kwiimpawu zepropathi ezihambelana nezinto ezinyulu ze-PTFE.

I-PTFE elungisiweyo inezi mpawu zintsha okanye ziphuculwe ngaphezulu kwe-PTFE eqhelekileyo:

Umphezulu wenxalenye ugudileyo, kwaye ungaphantsi kancinci - amalungu ahlala ecocekile kuba awafane abambe ungcoliseko Umgangatho osezantsi we-micro-void uvelisa ukuchaneka okuphuculweyo kwe-permeationUbomi obude obuguquguqukayo kune-PTFEUkonyuka kokuqina kunye nokuphucuka kokuxhathisa okurhubuluzayo Amandla edielectric aphezulu anika amandla ombane aphezulu ombane aphezuluFusible / Weldable (Isebenzisa iindlela ezahlukeneyo zokuwelda ubushushu kunye noxinzelelo oluphakathi)Imizekelo yeMigqomo & Iityhubhu ezenziwe kusetyenziswa i-APT's Modified PTFE Fusing & Machining Processes

I-PTFE imele i-Polytetrafluoroethylene, i-thermoplastic ye-fluorocarbon efumene usebenziso olubanzi kwizicelo zobunjineli kwaye yaziwa kakhulu ngokuba neyona coefficient isezantsi yokukhuhlana kwayo nayiphi na into eqinileyo.Ikwabizwa ngokuba yipolymer, Dyneon TM, 1,1,2,2-tetraflouroethene okanye 1,1,2,2-tetraflouroethylene.

Njengoko sele kukhankanyiwe, i-PTFE yenye yezona polymers ezingenazo iikhemikhali ezifumanekayo (iTshati yokuNxhathisa iChemical).Inokusebenzisa ubushushu obuqhubekekayo ukusuka ku -200°C ukuya kuma-250°C kwaye iyakwazi ukumelana nokufunxwa kwamanzi.Ukongeza, inokuziphatha okuchasene nokuncamathelisa okuchasene nokwakhiwa kwezinto eziqinileyo, okwenza kube lula kakhulu kwi-CIP (Coca endaweni).Enyanisweni, kukho amabanga ahlukeneyo e-PTFE avunyiweyo yi-FDA.

I-PTFE elungisiweyongokwekhemikhali kubhekiselwa kuyo njengepolytetrafluoroethylene, kunye negama lorhwebo iPolyflon.Yindibaniselwano enika umdla yeepropathi ze-PTFE kunye ne-PFA (Perfluoroalkoxy), eyaziwa ngeempawu zayo eziphezulu zoomatshini.

Njenge-PTFE, i-TFM ayisebenzi ngokwekhemikhali kwaye inoluhlu olufanayo lobushushu bokusetyenziswa okuqhubekayo, kunye nokumelana okufanayo nokufunxwa kwamanzi.Ikwagcina uninzi lweempawu ezinganamatheli ze-PTFE.

I-TFM ikwanomlinganiselo othe kratya wentlakohlaza, kodwa ngokuqaphelekayo iipropathi zokudinwa ngcono kwaye ibonisa ukuchacha koxinzelelo olungcono.Ukongeza, kulula ukuwelda kune-PTFE kwaye inobunzima obuncinci.I-TFM ikwaxhathisa kokubini i-embrittlement kunye nokuguga.

Enye into eyenza i-TFM ibe yodwa kukuxinana kwesakhiwo semolekyuli.Oku kubangela umlinganiselo ophantsi kakhulu wokungena kwegesi kubukhulu obufanayo bezinto xa kuthelekiswa ne-PTFE.Olu phawu lubaluleke kakhulu xa lusetyenziswa kwindawo enomhlwa kakhulu.Ngolwakhiwo olushinyeneyo lwemolekyuli, i-TFM ikwabonelela ngokugqityezelwa komphezulu ogudileyo loo PTFE.Kwakhona, njenge-PTFE, kukho amabanga awohlukeneyo e-TFM avunyiweyo yi-FDA.
