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 okha, mphamvu zolimba zimatsika kufika ~ 25% yazoyambirira. Ndikoyenera kokha kwa malo a mlingo wochepa (chakudya / kulera kwachipatala <10 kGy). Pamakampani a nyukiliya kapena zoyenda mumlengalenga, gwiritsani ntchito polyimide kapena PEEK m'malo mwake.

Tepi ya PTFE yotentha kwambiri imafuna kusungidwa koyenera kuti ikhale yomatira, kusinthasintha, ndi kutulutsa ntchito. Zofunikira zazikulu ndi kuwongolera kutentha (10-30 ° C), chinyezi chochepera 60%, kupewa kuwala, kudzipatula kwamankhwala, kuyika molunjika, ndi mpweya wabwino. Tsatirani kasamalidwe ka FIFO ndikuwunika pafupipafupi.

Nkhaniyi ikufotokoza momwe mungapewere kuipitsidwa ndi kuwonongeka kwa ntchito pa mbali yosamatira ya PTFE tepi yotentha kwambiri panthawi yophimba. Njira zazikuluzikulu zikuphatikiza kuyang'anira magwero (kuchiza molondola pamwamba), kudzipatula pathupi (makanema oteteza, zodzigudubuza zopanda ndodo, zowumitsa zone), ndikuwongolera njira zoyengedwa.

Monga opanga oyambirira a PTFE matepi otentha kwambiri, Jiangsu Aokai New Materials apa akulongosola zotsatira za njira zoziziritsira ndi kuziziritsa pakuchita kwa matepi ochiritsidwa a PTFE. Makhalidwe a PTFE Crystallization Makhalidwe ndi Kuzizira kwa Rate RegulationThe PTFE su

Jiangsu Aokai New Materials, katswiri wopanga tepi yotentha kwambiri ya PTFE, amagawana nzeru zamaluso kwa inu.PTFE (Teflon) tepi yotentha kwambiri imatha kugwiritsidwa ntchito mosalekeza pa kutentha kwa -196℃ mpaka 260℃. Mu ntchito zambiri, kutentha kukana malire
