Kuri PTFE kaseti yubushyuhe bukoreshwa mugukoresha abrasive kunyerera ya porogaramu, ibisanzwe bitari inkoni hamwe nubushyuhe ntibihagije. Ibipimo byingenzi byo gutoranya: Gutakaza ibibyimba (<15 mg / 1000 cycle), byuzuye byuzuye bya PTFE (karubone / grafite / MoS₂), amakuru ya PV ntarengwa, imbaraga zubutaka (≥200 N / cm), hamwe nuburinganire bwubuso (Ra 0.2-0.4 μm). Kurinda impande zose hamwe no guhuza byuzuye nibyingenzi kuramba.

Ibikoresho byo kurangiza bikoreshwa mubitambaro bya fiberglass mbere yo gutwikira PTFE nibyingenzi mubikorwa bya nyuma bya PTFE. Ibikoresho bifata organosilane birema ibiraro bya molekuline hagati ya fibre yikirahure idasanzwe na PTFE kama, bikongerera imbaraga ibishishwa kuva kuri <2 N / cm kugeza 4-8 + N / cm. Kuvura neza kandi byongera imbaraga zo kurwanya ubushyuhe (260 ° C +), imikorere ya dielectric, hamwe no kurwanya imiti. Imyenda itavuwe iganisha ku gusibanganya, kubyimba, no kubaho igihe gito.

Intambara hamwe nubudodo bwimyenda ya fiberglass igena imikorere ya PTFE yubushyuhe bwo hejuru. Ubucucike buri hejuru bwongera imbaraga zingirakamaro hamwe nubuso bworoshye ariko bigabanya imbaraga zamarira (inverted U-curve), guhinduka, no kwinjirira. Ubucucike bwiza buringaniza kwinjira, kurwanya amarira, guhinduka, no kurangiza hejuru. Ubucucike buke bukwiranye no kugonda; ubucucike bukabije kubutari inkoni.

PTFE substrate isanzwe irwanya umunyu (kwinjiza amazi <0.01%). Nyamara, muri rusange imikorere ya kaseti iterwa nubwoko bufatika: silicone PSA ihanganira ibidukikije byo mu nyanja (ibizamini byo gutera umunyu 500-1000h,> kubika 80%); acrylic PSA birananirana. Kuvura neza neza, kubusa kubusa, no gufunga impande hamwe na silicone kashe ni ingenzi kubwizerwa bwigihe kirekire kurubuga rwa interineti.

Calendering - gukanda umwenda ushyizweho na PTFE hagati yindorerwamo zishyushye zishyushye kuri 360-380 ° C - uhindura kuburyo bugaragara imiterere yimiterere, kurekura ibintu, kudahinduka, hamwe nubukanishi. Igabanya ubukana kuva kuri Ra 0.5-1.0 mkm kugeza kuri <0,05 mm, ifunga pinholes, itezimbere imyambarire, ariko igabanya imbaraga zamarira no guhinduka. Ibyingenzi kurekura imirongo hamwe no gukwirakwiza amashanyarazi.

Ububiko bwa fibre yububiko - busanzwe, twill, cyangwa satine - bigira ingaruka zikomeye kumiterere ya PTFE yubushyuhe bwo hejuru. Ububoshyi bwa Satin butanga imbaraga zo kurira cyane (2-3x igaragara) kandi byoroshye, nibyiza kugoreka imbaraga. Ububoshyi bwibibaya butanga icyerekezo cyiza kandi gihamye, gikwiranye na static progaramu. Twill iringaniza imitungo yose kugirango ikoreshwe muri rusange.

PTFE fiberglass kaseti isaba ibyemezo bitatu byingenzi byumutekano: UL (umutekano wamashanyarazi numuriro), FDA (kubahiriza ibiryo), na ISO 9001: 2015 (gucunga neza). Kaseti yemewe itanga imikorere ihamye, igihe kirekire cya serivisi, nigiciro gito cya nyirubwite nubwo igiciro kiri hejuru. Buri gihe ugenzure ibyemezo bitaziguye hamwe ninzego zitanga.

Imikandara ya PTFE (umukandara wa Teflon) itezimbere imirongo itunganya ibiryo binyuze mu nyungu enye zingenzi: imikorere isumba iyindi idafite inkoni (kugabanya imyanda no gufatana), kwihanganira ubushyuhe bwagutse (-100 ° C kugeza 260 ° C ituma guteka bikonjeshwa), gusukura byoroshye no kurwanya bagiteri (ubuso butari bubi, kubahiriza FDA), no kuzigama ibikorwa (gukoresha ingufu nke, ubuzima burebure). Bikwiranye nibicuruzwa bitetse, ibiryo bikonje, shokora, nibicuruzwa bifatanye.

PTFE yubushyuhe bwo hejuru ikoreshwa mubice bitatu byubuvuzi: kurinda ibikoresho byo kuboneza urubyaro (tray autoclave tray, gupakira ubushyuhe bwa kashe), kuvura ibikoresho byo hejuru (gutwika-friction nkeya, kubika amashanyarazi), hamwe nibikoresho byatewe (graft vasculaire, suture). Biocompatibilité igenzurwa hakoreshejwe ISO 10993, naho FDA 21 CFR 177.1550 ishyiraho umutekano wibikoresho fatizo.

Uburinganire bwimyenda ya PTFE yubushyuhe bwo hejuru bugenwa nimpamvu enye: gutondekanya (ingano ya 0.15-0.35 μ mm, viscosity, ibirimo bikomeye), gutwikira & gucumura (gutwikira icyuma gikundwa kuburinganire), ubuziranenge bwibisobanuro (kuboha, kubanza kubivura), hamwe nibidukikije (20-25 ° C, <60% RH). Dip + blade ikomatanyirijwe hamwe iringaniza kwinjira no kugaragara neza.
