I-EP PTFE Encapsulated O-Rings ihlanganisa ukumelana kwamakhemikhali ekugcineni kwe-FEP PTFE nekhono lokuminyanisa lerabha noma insimbi yasentwasahlobo.
Khetha ezinkethweni ezihlukene eziwumongo ukuze wanelise isicelo sakho.
Ukuqina kwe-FEP PTFE kungadinga ukwakheka kwendlala yangokwezifiso ukuze kwandiswe ukuvala ngokusebenzisa inani elifanele lamandla okucindezela ukuze kugcinwe uphawu ngaphandle kokucindezelwa ngokweqile okungafinyeza ukuphila kokuvala. I-FFKM kanye ne-Spring Energized Lip Seals ezinye izindlela.Amanye ama-diameter kanye nezingxenye eziphambanayo zincane kakhulu ukuthi zingakhiqizwa.
I-FFKM O-Rings kukhona nokunye.Uhlobo lwe-FEP i-PTFE Fluoropolymers (amapulasitiki okusebenza) anikeza ukumelana okuhle kakhulu kwamakhemikhali nezinga lokushisa, kodwa awanakho ukuqina kwama-elastomers (Fkm Rubber O Ring) okudingekayo ukuze kugcinwe uphawu lwekhwalithi. Izigxivizo ezihlanganisiwe nezinamandla zasentwasahlobo zihlanganisa izici ezingcono kakhulu zokuvala zamapulasitiki, ama-elastomers neziphethu zensimbi ukwandisa ukusebenza kwamakhemikhali nezinga lokushisa uma kuqhathaniswa nama-elastomer amaningi aqinile. Umkhawulo oyinhloko wokunciphisa ukuqina kwe-PTFE okungadinga ukwakheka kwendlala yangokwezifiso ukuze kwandiswe ukuvala ngokusebenzisa inani elifanele lamandla okucindezela ukuze kugcinwe uphawu ngaphandle kokucindezelwa ngokweqile okunganciphisa ukuphila kophawu. I-PFA yohlobo lwe-PTFE iyatholakala futhi ekwengezeni ukumelana nezinga lokushisa okuphezulu (kufika ku-+575° F ukuchayeka okufushane) kodwa ayisetshenziswa kakhulu ngenxa yokuncipha kokusebenza kokuvala.O-Ring ene-FEP PTFE ungqimba lwangaphandle oluhlanganisa umgogodla weSilicone. Igobolondo le-PTFE linikeza ukumelana okuhle kwamakhemikhali nokushisa ngenkathi i-I-Rubber Silicone Seal O Ringi-core inikeza ukuqina okudingekayo ukuze kuhlinzekwe ukuvala okusebenzayo. Okutholakala kalula yi-USA kanye nezigaba eziphambanayo zemethrikhi kanye namadayamitha angenamkhawulo. I-T1002 i-FEP ifakwe ku-Solid Silicone kuze kufike ku-+500o F kuye ngokusebenza. I-PFA thayipha i-PTFE T1027 ifika ku-+575o F kuye ngohlelo lokusebenza.
I-O-Ring enesendlalelo sangaphandle se-FEP PTFE esihlanganisa umongo we-Solid FKM (Viton). Igobolondo le-PTFE linikeza ukumelana okuhle kakhulu kwamakhemikhali nezinga lokushisa kuyilapho umnyombo we-FKM unikeza ukuqina okudingekayo ukuze kuhlinzekwe uphawu olusebenzayo. Umnyombo we-FKM uhlinzeka ngamakhemikhali athuthukisiwe ukumelana nesethi yokucindezelwa okuholela ekuphileni kokuvala isikhathi eside kwezinye izinhlelo zokusebenza. Icindezela kancane kune-Silicone engaholela ezinkingeni ezivuzayo kwezinye izinhlelo zokusebenza. Okutholakala kalula yi-USA kanye nezigaba eziphambanayo zemethrikhi kanye namadayamitha angenamkhawulo.
I-T1001 yi-FEP ehlanganiswe ne-Solid FKM (I-Viton Rubber noma Indandatho) kufika ku-+500oF kuye ngohlelo lokusebenza. Wonke usayizi Uyatholakala.
