I-PTFE, i-FEP kunye ne-PFA zezona ziyaziwa kakhulu kwaye ziqhelekileyo ii-fluoroplastics.Kodwa yintoni, ngokwenene, umahluko wabo?Fumanisa ukuba kutheni i-fluoropolymers zizinto ezikhethekileyo, kwaye yeyiphi i-fluoroplastic eyona ifanele isicelo sakho.
Iimpawu ezizodwa ze-fluoroplastics
IiFluoropolymers zonwabela iipropathi ezininzi ezizodwa ezizenza zilungele ukusetyenziswa kwezonyango, iimoto, umbane kunye nezicelo zasekhaya, phakathi kwabanye.
I-Fluoroplastics ineempawu ezilandelayo:
1.Ubushushu bokusebenza obuphezulu kakhulu
2.Uphawu lokungakhuni
3.Umgangatho ophantsi wokukhuhlana
4.Ukuchasana okuphezulu kakhulu kwiikhemikhali kunye ne-solvents
5.Ukumelana nombane okuphezulu kakhulu
IiFluoroplastics ezahlukeneyo zonwabela iiyantlukwano ezifihlakeleyo, kubandakanywa amaqondo obushushu ahlukeneyo okusebenza, kwaye zilungele izicelo ezahlukeneyo.Ukuba ikhethwe ngokuchanekileyo, i-fluoropolymers inokuhambisa ixabiso elihle kunye neenzuzo zokusebenza.
Iinzuzo ze-PTFE
PTFE, okanye iPolytetrafluoroethylene, nguyisemkhulu wazo zonke i-fluoroplastics.Ifunyanwe ngusosayensi uRoy J. Plunkett ngo-1938, i-PTFE iyona nto i-fluoropolymer engavamile kwaye ibonisa ukusebenza kakuhle ngokubhekiselele kwiqondo lokushisa, ukuchasana kweekhemikhali kunye neepropati ezingezizo.
Ukongeza ekonwabeni iipropathi ezizodwa ze-fluoroplastics, i-PTFE iyazohlula ngokuba nezi zibonelelo zilandelayo:
I-1.Ixabiso elingcono kakhulu: umlinganiselo wokusebenza
2.Ubushushu bokusebenza obuqhubekayo +260°C - Eli lelona qondo liphezulu lokusebenza kuyo nayiphi na i-fluoroplastic
3.Ukumelana nayo yonke imichiza
4.Ukungancamatheli kakhulu (nokuba unqinishe unokutyibilika kwi-PTFE)
5.Umbala oqaqambileyo
Eyona nto ingalunganga ye-PTFE kukuba ayinyibiliki xa ishushu kwaye ke kunzima ukuyiqhuba.Iindlela ezingaqhelekanga kakhulu ziyafuneka ukubumba, ukukhupha kunye nokutshisa le fluoropolymer.
Ngenxa yeepropati zayo ezizodwa, i-PTFE ilungele ukusetyenziswa kwi-insulation yombane kunye nokukhuselwa kwezinto zombane.
Singumenzi oqeqeshiweyo weumbhobho weptfe, ukuba unayo nayiphi na imibuzo, ungaqhagamshelana nathi!
Iinzuzo ze-FEP
I-FEP, okanye iFluoroethylenepropylene, yinguqulelo enyibilikayo enokunyibilika ye-PTFE.I-FEP ineempawu ezifanayo kakhulu ne-PTFE, kodwa inobushushu obusezantsi obuphezulu bokusebenza obuyi +200°C.Nangona kunjalo, i-FEP inokucutshungulwa ngokulula kwaye inokudityaniswa ngokulula kwaye iphinde ibunjwe ibe ziinkangeleko ezintsonkothileyo.
Kanye nokuba neempawu ezizodwa ze-fluoroplastics, i-FEP iyazonwabela ezi zibonelelo:
1. Ukuwelda kunye nokuphinda ukubumba amandla
2.Amaqondo obushushu okusebenza okusebenza -200 ° C ukuya +200 ° C - FEP ihlala iguquguquka kumaqondo obushushu cryogenic
3.Ukuchasana okupheleleyo kwiikhemikhali kunye ne-UV
4.I-Bio-iyahambelana
5. Umbala ocacileyo
Enkosi kwezi zibonelelo, ubushushu be-FEP bucutheka bunobushushu obuphantsi kwaye bunokucutheka ngokukhuselekileyo phezu kwemathiriyeli ebuthathaka kubushushu ngaphandle koloyiko lokubangela umonakalo.Ngenxa yoko, i-FEP ilungele ukufaka izixhobo zombane ezibuthathaka kunye nezixhobo.
Izibonelelo zePFA
I-PFA, okanye i-Perfluoralkoxy, yinguqulelo yobushushu obuphezulu be-FEP.I-PFA ineempawu ezifanayo kwi-FEP kodwa ingasetyenziselwa kumaqondo obushushu asebenzayo ukuya kuthi ga kwi-+260 ° C ngelixa isala i-nyibilika-iqhubekeke, ngenxa ye-viscosity ephantsi yokunyibilika kune-PTFE.
Ukongeza ekonwabeni iipropathi ezizodwa ze-fluoropolymers, iPFA iyazahlula ngokuba nezi zibonelelo zilandelayo:
Ubushushu bokusebenza obuqhubekayo +260°C - Eli lelona qondo liphezulu lokusebenza kuyo nayiphi na i-fluoroplastic
1.I-Welding kunye nokuphinda ukubumba amandla
2.Good permeability ukumelana
3.Ukumelana neekhemikhali ezigqwesileyo, nakwiqondo lokushisa eliphakamileyo
4.I-Bio-iyahambelana
5.Amabakala aphezulu okucoceka akhoyo
6.Umbala ocacileyo
Eyona nto ingalunganga ye-PFA kukuba ibiza kakhulu kune-PTFE kunye ne-FEP.
I-PFA ifanelekile kwizicelo ezifuna ibakala eliphezulu lokucoceka, ukuchasana kweekhemikhali okugqwesileyo kunye nobushushu obuphezulu bokusebenza.Le fluoroplastic isetyenziswa kakhulu kwiityhubhu zonyango, ukutshintshiselana kobushushu, iibhaskithi zesemi-conductor, iimpompo kunye nezinto zokufakelwa, kunye ne-valve liners.
