PTFE fiberglass tepi inoda zvitupa zvitatu zvakakosha zvekuchengetedza: UL (kuchengetedzwa kwemagetsi nemurazvo), FDA (kuenderana kwechikafu), uye ISO 9001: 2015 (mhando yekutonga). Matepi akasimbiswa anopa kuita kwakafanana, hupenyu hwesevhisi hurefu, uye mutengo wakaderera wevaridzi kunyangwe mutengo wepamberi wepamusoro. Gara uchisimbisa zvitupa zvakananga nemasangano anoburitsa.

PTFE conveyor belts (Teflon belts) inovandudza mitsara yekugadzira zvokudya kuburikidza nemabhenefiti mana anokosha: hukuru husina-tsvimbo (inoderedza marara uye kunamatira), kushivirira kwekushisa kwehupamhi (-100 ° C kusvika 260 ° C inogonesa kubheka kutonhora), kuchenesa nyore uye kupikisa kwebhakitiriya (isina-porous surface, FDA inowirirana, uye kushandiswa kwehupenyu kwenguva refu). Inokodzera zvakabikwa, chikafu chakaomeswa nechando, chokoreti, uye zvinonamira zvigadzirwa.

PTFE high-temperature tepi inoshandiswa pamativi matatu ekurapwa kwemishonga: kudzivirira midziyo yekudzivirira (autoclave trays, heat-seal packaging), chiridzwa chepamusoro kurapwa (low-friction coating, electrical insulation), uye midziyo inoisirwa (vascular grafts, sutures). Biocompatibility inosimbiswa kuburikidza neISO 10993, uye FDA 21 CFR 177.1550 inogadza hwaro hwekuchengetedza zvinhu.

Coating uniformity yePTFE high-temperature jira inotarirwa nezvinhu zvina: coating formulation (particle size 0.15-0.35 μm, viscosity, solid content), coating & sintering process (blade coating inosarudzwa kuti ifanane), substrate quality (weave pattern, pre-treatment), uye kugadzirwa nharaunda (20-25% R <60%). Dip + blade yakasanganiswa maitiro anoyera kupinda uye kutsetseka kwepamusoro.

PTFE pamusoro pekurapa kwekubatanidza adhesion inoshandisa nzira mbiri huru: kunyungudika kwepamusoro-kunyunguduka (yepamusoro-soro yemamiriro ekunze, 9.5 MPa simba rine coupling agent, asi inobudisa magasi ane chepfu) uye sodium-naphthalene etching (5 MPa pakarepo kunamatira, nhete 24-48 awa hwindo, tsvina ine ngozi). Sarudza zvichibva pakutonga kwezvakatipoteredza uye kwenguva yakareba vs.

Kuchenesa uye kugadzirisa kwakakodzera kunowedzera hupenyu hwePTFE yakakwirira-tembiricha machira. Kuchenesa mushure mekushandisa uye mushure mekutonhora. Shandisa mabhurashi akapfava, simbi dzisina divi, kana doro kuitira tsvina. Usamboshandisa akasimba acids/alkalis, bleach, kana metal scrapers. Yenguva dzose silicone mafuta lubrication inoderedza kupfeka. Tevedzera izvi zvinongedzo kuti udzivise kukuvara kwejasi.

PTFE high-temperature tepi ine kushomeka kwekudzivirira kune ionizing mwaranzi. Pakungoratidzwa kwe1 kGy gamma, simba rekusimba rinodonha kusvika ~ 25% yepakutanga. Inokodzera chete kune yakaderera-dose nharaunda (chikafu / chekurapa sterilization <10 kGy). Kune indasitiri yenyukireya kana spacecraft, shandisa polyimide kana PEEK pachinzvimbo.

Kuedza PTFE emulsion quality kunosanganisira zvitanhatu zvakakosha zviratidzo: yakasimba content (60±2% per T/FSI 067-2021), pH (9.0-11.0), particle size distribution (laser diffraction/DLS), viscosity (12-30 mPa·s pa 25°C), kugadzikana (centrifugal, freeze-rthaw). Iri gwara rinofukidza akajairwa bvunzo nzira kune yega yega parameter.

Kune PTFE yepamusoro-tembiricha matepi pasi pekunyudzwa kwenguva refu, iyo PTFE substrate inoramba iine chemikemikari inert, asi iyo yekunamatira layer ndiyo isina simba. Mvura inopedza silicone PSA; mvura yemunyu inokurumidza kuita ngura. Kune makemikari ane hukasha, fluorosilicone kana perfluoropolyether adhesives - kana adhesive-isina PTFE tepi - inodiwa. Peel simba kurasikirwa kusvika ku40% mushure memaawa makumi mana nemasere mumvura.

PTFE high-temperature tepi inoshandiswa mumapurogiramu ekutsvaga kwezvokudya inofanira kugara mukati memiganhu yakatsanangurwa yekushisa: ≤260 ° C kuti irambe ichishandiswa, ≤300 ° C kwepamusoro pepamusoro (maminitsi), uye isingambopfuuri 327 ° C (kuora). FDA neEU mirau haitsanangure nguva yakatarwa - nguva yakachengeteka yekubata inoenderana nekupisa uye inofanirwa kusimbiswa nemiedzo yekufambisa inoteedzera mamiriro chaiwo.
