Gawo laling'ono la PTFE ndilosamva kupopera kwa mchere (mayamwidwe amadzi <0.01%). Komabe, ntchito ya tepi yonse imadalira mtundu womatira: silikoni PSA imalimbana ndi malo am'madzi (500-1000h mayeso opopera mchere,> 80% kusunga peel); acrylic PSA amalephera. Kusamalira bwino pamtunda, kugwiritsa ntchito zopanda thovu, ndi kusindikiza m'mphepete ndi silicone sealant ndizofunikira kuti mukhale odalirika kwa nthawi yayitali pamapulatifomu ndi zombo zapanyanja.

Tepi ya fiberglass ya PTFE imafuna ziphaso zitatu zazikulu zachitetezo: UL (chitetezo chamagetsi ndi moto), FDA (kutsata kukhudzana ndi chakudya), ndi ISO 9001:2015 (kasamalidwe kabwino). Matepi ovomerezeka amapereka magwiridwe antchito nthawi zonse, moyo wautali wautumiki, komanso kutsika mtengo kwa umwini ngakhale mtengo wake ukukwera. Nthawi zonse muzitsimikizira ziphaso mwachindunji ndi mabungwe omwe akupereka.

Tepi ya PTFE yotentha kwambiri imagwiritsidwa ntchito pamiyezo itatu yachipatala: chitetezo cha zida zotsekereza (mathirelo a autoclave, zotsekera zotsekera kutentha), chithandizo chapamwamba cha zida (zotchingira zotsika, zotchingira magetsi), ndi zida zotsekera (zolumikizira mitsempha, zolumikizira). Biocompatibility imatsimikiziridwa kudzera mu ISO 10993, ndipo FDA 21 CFR 177.1550 imakhazikitsa chitetezo chazinthu zoyambira.

Tepi yotentha kwambiri ya PTFE ili ndi kukana koyipa kwa radiation ya ionizing. Pamawonekedwe a 1 kGy a gamma, mphamvu zamphamvu zimatsika kufika ~ 25% yapachiyambi. Ndikoyenera kokha kwa malo otsika kwambiri (chakudya / kutseketsa kwachipatala <10 kGy). Pamakampani a nyukiliya kapena zoyenda zakuthambo, gwiritsani ntchito polyimide kapena PEEK m'malo mwake.

Kwa PTFE matepi otentha kwambiri pansi pa kumizidwa kwa nthawi yaitali, gawo lapansi la PTFE limakhalabe ndi mankhwala, koma zomatira ndizopanda mphamvu. Madzi amafooketsa silikoni PSA; madzi amchere amathandizira kuti dzimbiri. Pa mankhwala aukali, zomatira za fluorosilicone kapena perfluoropolyether - kapena tepi ya PTFE yopanda zomatira - ndiyofunika. Kutaya mphamvu kwa peel mpaka 40% pambuyo pa maola 48 m'madzi.

Tepi ya PTFE yotentha kwambiri yomwe imagwiritsidwa ntchito pokhudzana ndi chakudya iyenera kukhala mkati mwa malire omwe akufotokozedwa: ≤260 ° C kuti agwiritsidwe ntchito mosalekeza, ≤300 ° C kwa nsonga zazifupi (mphindi), ndipo osapitirira 327 ° C (kuwola). Malamulo a FDA ndi EU samatchula malire anthawi zonse - nthawi yolumikizana yotetezeka imadalira kutentha ndipo iyenera kutsimikiziridwa ndi mayeso osamukira kutengera momwe zinthu ziliri.

Tepi ya PTFE yotentha kwambiri imatha kusweka kapena kusweka pansi pa kupindika mobwerezabwereza ndi kutsegulira. Nkhaniyi ikufotokoza momwe mungapewere izi kudzera mu kusankha koyenera kwa gawo lapansi (magalasi owonjezera), makulidwe oyenera (0.18mm ngati muyezo), kusankha zomatira za silicone, ndi njira zoyenera zoyika.

Kusankhidwa kwa pepala lotulutsa kapena gawo laling'ono la filimu ndi wothandizira kumasula kumakhudza mwachindunji kukhazikika kwa kusungirako ndi kupukuta kwa PTFE tepi yotentha kwambiri. Nkhaniyi ikufanizira magawo a mapepala a PET vs kraft ndi silicone vs.

Matepi a PTFE omwe amawotcha kwambiri amagwiritsidwa ntchito kwambiri pakutchinjiriza magetsi, koma kuchuluka kwa ma frequency ndi ma voltage apamwamba kumabweretsa zoopsa zapadera: kuwonongeka kwamagetsi, kutulutsa pang'ono, kukalamba kwamafuta, kutayika kwa ma frequency apamwamba, komanso kukhudzidwa kwa chilengedwe. Nkhaniyi ikufotokoza ngozi iliyonse komanso mmene tingapewere.

Monga katswiri wopanga nsalu za PTFE zotentha kwambiri, Jiangsu Aokai New Materials amagawana nanu chidziwitso chofunikira pamakampani. Kuwombera m'mphepete ndi kugwa kwa matepi a PTFE kutentha kwakukulu sikumayambika kawirikawiri ndi chinthu chimodzi, koma chifukwa cha zotsatira zosakanikirana za kusankha kosayenera kwa tepi,
