PTFE: bambo wa fluoroplastics
PTFE ndi chiyani?
Posachedwaolymer pawiri zopangidwa tetrafluoroethylene ndi polymerization, PTFE ali kwambiri kukhazikika mankhwalandikukana dzimbiri,ndipo wakhalachimodzi mwa zidandi zabwinocorrosion resistance.PTFE ikhozakutsutsapafupifupi onsemankhwala,kupatulachitsulo chosungunuka cha alkali, chlorine trifluoride, chlorine pentafluoride ndi chlorine yamadzi, zakhala chonchoamagwiritsidwa ntchito kwambiri muzosiyanasiyananthawito kukana asidi ndi zosungunulira organic.PTFE palokha si poizoni kwa anthu.
Makhalidwe apadera a PTFE
PTFE ndiye fluoropolymer yachilendo kwambiri ndipo imawonetsa magwiridwe antchito abwino kwambiri potengera kutentha, kukana kwamankhwala ndi zinthu zopanda ndodo.
● Zopanda ndalama;
● Cntchito mosalekezaat kutentha kwa +260 ° C;
● Low kukangana pamwamba;
● Very high magetsi kukana.
Mapulogalamu a PTFE
● Malinga ndiOpanga PTFE, PTFE ili ndi zotsatirazi zazikulu ntchito.
●Ekupirira ngakhale madera ovuta kwambiri ndipo ndi oyenera kugwiritsidwa ntchito pazinthu zambiri.
●Ikugwiritsidwa ntchito pakupanga zakudya ndi zakumwa,kuphatikizapozipangizo kuphika, conveyor lamba odzigudubuza, sanali ndodo pamwamba chimakwirira,ndikutentha kwa sensor casing.
●Pmakamaka zothandiza kupanga mkati ndi kunja zida zopulumutsa moyo.
●Pchabwino kwa kutchinjiriza kwamagetsi ndi kuteteza zida zamagetsi.
● Panganimankhwala osiyanasiyanain makampani a Chemical,mongagaskets,zomangira zotengera ndi akasinja mankhwala.
PTFE Yowonjezera: microporous fluoropolymer
Kodi PTFE yowonjezera ndi chiyani?
Expanded PTFE (ePTFE) ndi mtundu watsopano wa zinthu zachipatala za polima, zomwe zimapangidwa ndi polytetrafluoroethylene resin potambasula ndi njira zina zapadera zopangira.PTFE yoyera, yotanuka komanso yosinthika yokulirapo ili ndi mauna opangidwa kudzera mu kulumikizana kwa microfiber, ndipo ma microfibers amapanga pores osawerengeka, kotero kuti PTFE yokulitsidwa ikhoza kupindika mosasamala.Kugwirizana kwa magazi ake komanso kukana kukalamba kwachilengedwe kumalola kuti igwiritsidwe ntchito popanga mitsempha yamagazi, zotupa zamtima ndi zinthu zina zamankhwala ndikukhala cholowa m'malo mwachilengedwe chachilengedwe.Ndi biocompatibility yabwino ndi mawonekedwe apadera a microporous, ePTFE ndi yopanda poizoni, yopanda khansa, komanso yopanda allergenic, ndipo sichidzatulutsa zotsatira zina.Maselo amtundu wamunthu ndi mitsempha yamagazi amatha kukula kukhala ma micro-pores ake kenako ndikupanga kulumikizana kwa minofu ngati minofu ya autologous.
Zapadera za PTFE yokulitsidwa
PTFE Yowonjezera imagawana zinthu zofanana ndi PTFE.Zinthuzi ndi zopanda poizoni komanso zaukhondo, komanso zimapereka kutentha kogwira ntchito mpaka 260 ° C.Kuphatikiza apo, ePTFE imasangalala ndi zotsatirazikatundu.
● Kugonjetsedwa ndi mankhwala ndi mphamvu zambiri za mzere;
● Osagwiritsa ntchito mankhwala;
● Kusalowa madzi pakathamanga kwambiri;
● Low dielectric constant;
● Kukula kwabwino kwa radial ndi kukana kwa UV.
Mapulogalamu a ePTFE
1. Implants zachipatala
EPTFE ya inert yokhazikika ingagwiritsidwe ntchito m'njira zosiyanasiyana zochiritsira, kuphatikizapo mitsempha yamagazi ndi zigamba zotsitsimutsa minofu yofewa komanso opaleshoni yopangira opaleshoni ya mitsempha, mtima, mitsempha ndi mafupa, potero amapindula madokotala ndi odwala.TheMankhwala a ePTFE amatha kugwira ntchito mogwirizana ndi minofu ya thupi lawo ndikubwezeretsa ntchito yawo yanthawi zonse.
2. Fluorofiber
Expanded PTFEulusikukhalakulimba kwambiri, kuchepa pang'ono, kukana abrasion, komanso kukana kwambiri kwa UV,kutikutsimikizirandikukhazikika bwino ndi kukhulupirika m'malo ovuta kwambiri.Izimtundu waCHIKWANGWANI chimagwira ntchito mosiyanasiyana ndipo chimatha kulukidwa, kupota, kuluka kapena kusokedwa munsalu zosiyanasiyana, kuphatikizapo kupanikizana, ulusi wosoka, nsalu zomangira ndi floss yamano.
3. Gaskets ndi sealant
ePTFE ili ndi kukana kwambiri kwamankhwala ndi abrasion komanso kukana kwambiri kutentha kwambiri komanso kutsika, ndikupangitsa kuti ikhale yoyenera kunyamula ndi kusindikiza.ofmadzi a m'mafakitale.Ma gaskets ndi zinthu zosindikizira kuchokeraSuko, kuphatikizapo lathyathyathya, mikwingwirima yopyapyala ndi zosindikizira zopangidwa kumunda, zimapezeka pama flanges amtundu uliwonse kapena mawonekedwe.
