PTFE fiberglass tepi imafuna ziphaso zitatu zazikulu zachitetezo: UL (chitetezo chamagetsi ndi lawi lamoto), 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 pamigawo itatu yamankhwala: chitetezo cha zida zotsekereza (mathirelo a autoclave, zotsekera zotsekera kutentha), chithandizo chapamwamba cha zida (zotchingira zotsika kwambiri, zotchingira magetsi), ndi zida zotsekera (mitsempha ya 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 ndizofooka. 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 atchulidwa kutentha: ≤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.

Kusankha tepi yoyenera ya PTFE yotentha kwambiri ya 3D chosindikizira chotentha bedi kumafuna kuyang'ana pa zizindikiro zinayi zazikulu: kukana kutentha (mpaka 260 ° C+), fiberglass-reinforced substrate (0.18mm yabwino), zomatira za silicone zopanda ndodo pamwamba, ndi m'lifupi / kulolera koyenera. Bukuli limakuthandizani kuti mupewe kupotoza, kutsalira, ndi kulephera kusindikiza.

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.
