PTFE substrate inogara munyu pfapfaidzo inoshingirira (kunwa mvura <0.01%). Zvisinei, kushanda kwematepi kunoenderana nemhando yekunamatira: silicone PSA inomira munzvimbo dzegungwa (500-1000h salt spray test,> 80% peel retention); acrylic PSA inokundikana. Kurapwa kwakaringana kwepamusoro, kunyorera-isina bubble, uye kuvharika kwemupendero nesilicone sealant kwakakosha pakuvimbika kwenguva refu pamapuratifomu ekunze nemidziyo.

PTFE fiberglass tepi inoda zvitupa zvitatu zvakakosha zvekuchengetedza: UL (kuchengetedzwa kwemagetsi uye murazvo), FDA (chikafu chekubata kutevedza), 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 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.

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.

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 muzvikumbiro zvekusangana kwechikafu 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 yepasirese yenguva - yakachengeteka yekubata nguva inoenderana nekupisa uye inofanirwa kusimbiswa nemiedzo yekufambisa inoteedzera mamiriro chaiwo.

PTFE high-temperature tepi inogona kutsemuka kana kutsemuka pasi pekudzokorora kukotama uye kuvhura mamiriro. Ichi chinyorwa chinotsanangura maitiro ekudzivirira izvi kuburikidza neakakodzera substrate kusarudzwa (girazi fiber yakasimbiswa), yakakwana ukobvu (0.18mm seyakajairwa), silicone adhesive sarudzo, uye kwakaringana nzira dzekuisa.

Sarudzo yebepa rekuburitsa kana firimu substrate uye mumiriri wekuburitsa zvinokanganisa kugadzikana kwekuchengetedza uye peeling kuita kwePTFE yakakwirira-temperature tepi. Ichi chinyorwa chinofananidza PET vs. kraft paper substrates uye silicone vs. fluorinated release agents, inokurudzira kusanganiswa kwakanyatsonaka kwezero-residue peeling uye kuvimbika kwenguva refu.

PTFE high-temperature matepi anoshandiswa zvakanyanya pakuvhara magetsi, asi high-frequency uye high-voltage mamiriro ezvinhu anokonzera njodzi dzakasiyana: kuparara kwemagetsi, kupera zvishoma, kuchembera kwekushisa, kurasikirwa kwechiratidzo chepamusoro, uye kunzwisiswa kwezvakatipoteredza. Chinyorwa chino chinotsanangura njodzi yega yega uye nzira yekuinzvenga nayo.

Senyanzvi yekugadzira PTFE machira ekushisa kwepamusoro, Jiangsu Aokai New Materials anogovera ruzivo rwakakodzera indasitiri newe. Edge warping uye kudonha kubva kuPTFE yakakwirira tepi matepi haawanzo kukonzerwa nechinhu chimwe chete, asi mhedzisiro kubva kune yakasanganiswa mhedzisiro yekutadza kusarudzwa tepi,
