Fiberglass weave pattern - plain, twill, kapena satin - imakhudza kwambiri PTFE katundu wa nsalu yotentha kwambiri. Satin weave imapereka mphamvu zong'ambika kwambiri (2-3x plain) komanso kusinthasintha, koyenera kupindika mwamphamvu. Plain weave imapereka kukhazikika kwapamwamba kwambiri komanso kumamatira kwa peel, koyenera kugwiritsa ntchito static. Twill imalinganiza zinthu zonse kuti zigwiritsidwe ntchito.

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.

PTFE conveyor malamba (Teflon malamba) amawongolera mizere yopangira chakudya kudzera m'maubwino anayi ofunikira: magwiridwe antchito apamwamba (amachepetsa zinyalala ndi kumamatira), kulekerera kutentha kwakukulu (-100 ° C mpaka 260 ° C kumathandizira kuphika kuzizira), kuyeretsa kosavuta ndi kukana kwa bakiteriya (kupanda porous, FDA kutsata, kugwiritsa ntchito mphamvu kwanthawi yayitali), komanso kugwiritsa ntchito mphamvu kwanthawi yayitali. Zoyenera kuphika, zakudya zozizira, chokoleti, ndi zomata.

Tepi ya PTFE yotentha kwambiri imagwiritsidwa ntchito pamigawo itatu yamankhwala: chitetezo cha zida zotsekereza (mathirelo a autoclave, zotsekera zotsekera kutentha), chithandizo chapamwamba ch�zida (zotchingira zotsika kwambiri, zotchingira magetsi), n=2>. M'zida zamankhwala, ikugwiritsidwa ntchito muzinthu zoyikika chifukwa cha biocompatibility yake komanso kusachitapo kanthu. Kuthekera kwa nsaluyi pamakina operekera mankhwala akufufuzidwanso, kutengera mphamvu zake zowongolera. Mu biotechnology, malo okhala ndi PTFE akugwiritsidwa ntchito popanga ma cell culture, kupereka gawo loyenera la kukula kwa maselo ndi kuchulukana.

❖ kuyanika yunifolomu wa PTFE mkulu kutentha nsalu anatsimikiza ndi zinthu zinayi: ❖ kuyanika chiphunzitso (tinthu kukula 0.15-0.35 μm, mamasukidwe akayendedwe, okhutira olimba), ❖ kuyanika & sintering ndondomeko (tsamba ❖ kuyanika ankakonda kuti chifanane), gawo lapansi khalidwe (yokhotakhota chitsanzo, chisanadze mankhwala), ndi chilengedwe kupanga (20-25% R <60% <60). Dip + blade kuphatikiza njira yolowera ndi kusalala kwa pamwamba.

PTFE pamwamba mankhwala kwa kugwirizana adhesion amagwiritsa ntchito njira zikuluzikulu ziwiri: mkulu-kutentha kusungunuka (apamwamba nyengo kukana, 9.5 MPa mphamvu ndi coupling wothandizila, koma kutulutsa mpweya poizoni) ndi sodium-naphthalene etching (5 MPa mwamsanga adhesion, yopapatiza 24-48 ora zenera, zinyalala zoopsa). Sankhani potengera kuwongolera chilengedwe komanso nthawi yayitali vs.

Kuyeretsa ndi kukonza moyenera kumakulitsa moyo wa nsalu za PTFE zotentha kwambiri. Chotsani mukatha kugwiritsa ntchito komanso mukazizilitsa. Gwiritsani ntchito maburashi ofewa, zotsukira zopanda ndale, kapena mowa popaka madontho. Musagwiritse ntchito zidulo zolimba/ma alkali, bulichi, kapena zopalira zitsulo. Kupaka mafuta nthawi zonse kumachepetsa kuvala. Tsatirani malangizowa kuti mupewe kuwonongeka kwa zokutira.

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.

Kuyesa PTFE emulsion khalidwe kumafuna zizindikiro zisanu ndi chimodzi zofunika: okhutira olimba (60 ± 2% pa T/FSI 067-2021), pH (9.0-11.0), tinthu kukula kugawa (laser diffraction/DLS), mamasukidwe akayendedwe (12-30 mPa · s pa 25 ° C), bata (centrifugal, freeze-thaw, mawonekedwe). Bukhuli limafotokoza njira zoyeserera zoyeserera pagawo lililonse.

Kwa PTFE matepi otentha kwambiri pansi pa kumizidwa kwa nthawi yaitali, gawo lapansi la PTFE limakhalabe ndi mankhwala, koma zomatira ndi
