PTFE fiberglass daim kab xev yuav tsum muaj peb daim ntawv pov thawj kev nyab xeeb tseem ceeb: UL (kev nyab xeeb hluav taws xob thiab nplaim taws), FDA (kev sib cuag zaub mov), thiab ISO 9001: 2015 (kev tswj kom zoo). Cov ntaub ntawv pov thawj muaj kev ua tau zoo, kev ua haujlwm ntev dua, thiab txo tus nqi ntawm cov tswv cuab txawm tias tus nqi siab dua. Ib txwm txheeb xyuas cov ntawv pov thawj ncaj qha nrog lub cev tawm.

PTFE high-temperature daim kab xev yog siv nyob rau hauv peb cov ntaub ntawv kho mob tiers: sterilization cov cuab yeej tiv thaiv (autoclave trays, tshav kub-seal ntim), ntsuas nto kev kho mob (tsawg-kev sib txhuam txheej, hluav taws xob rwb thaiv tsev), thiab implantable devices (vascular grafts, sutures). Biocompatibility raug txheeb xyuas los ntawm ISO 10993, thiab FDA 21 CFR 177.1550 tsim cov khoom siv kev nyab xeeb.

PTFE high-temperature daim kab xev tsis zoo rau ionizing hluav taws xob. Thaum tsuas yog 1 kGy gamma raug, lub zog tensile poob rau ~ 25% ntawm thawj. Nws tsuas yog tsim nyog rau qhov chaw qis qis (khoom noj / kho mob kom tsis muaj menyuam <10 kGy). Rau kev lag luam nuclear lossis lub dav hlau, siv polyimide lossis PEEK hloov.

Rau PTFE high-temperature tapes nyob rau hauv lub sij hawm ntev immersion, PTFE substrate tseem chemically inert, tab sis cov nplaum txheej yog qhov tsis muaj zog. Dej tsis muaj zog silicone PSA; dej ntsev accelerates corrosion. Rau cov tshuaj phem, fluorosilicone los yog perfluoropolyether adhesives - los yog nplaum-dawb PTFE daim kab xev - yuav tsum tau. Peel lub zog poob mus txog 40% tom qab 48 teev hauv dej.

PTFE high-temperature daim kab xev siv nyob rau hauv daim ntawv thov kev sib cuag zaub mov yuav tsum nyob rau hauv cov kev txwv kub: ≤260 ° C rau kev siv tas mus li, ≤300 ° C rau luv peaks (feeb), thiab tsis txhob siab tshaj 327 ° C (decomposition). FDA thiab EU cov kev cai tsis qhia txog lub sijhawm txwv thoob ntiaj teb - lub sijhawm tiv thaiv kev nyab xeeb nyob ntawm qhov ntsuas kub thiab yuav tsum tau txheeb xyuas los ntawm kev kuaj kev tsiv teb tsaws simulating cov xwm txheej.

PTFE high-temperature daim kab xev yuav tsum tau cia kom zoo kom nws adhesion, yooj, thiab tso tawm kev ua tau zoo. Cov kev cai tseem ceeb suav nrog kev tswj qhov kub thiab txias (10-30 ° C), cov av noo qis dua 60%, kev zam lub teeb, kev cais tshuaj lom neeg, kev tso chaw ntsug, thiab qhov cua. Ua raws li FIFO kev tswj cov khoom muag thiab tshuaj xyuas tsis tu ncua.

Xaiv txoj cai PTFE high-temperature daim kab xev rau 3D tshuab luam ntawv kub txaj yuav tsum tau tsom rau plaub qhov tseem ceeb ntsuas: kub tsis kam (txog 260 ° C +), fiberglass-reinforced substrate (0.18mm zoo tagnrho), silicone nplaum nplaum nrog cov tsis-stick saum npoo, thiab kom dav / kam rau ua. Cov lus qhia no pab koj kom tsis txhob muaj kev sib tsoo, qhov seem, thiab luam tawm tsis ua haujlwm.

Cov iav hloov pauv kub (Tg) ntawm silicone siab-rhiab nplaum nplaum yog nyob ib ncig ntawm -120 ° C - qis dua li acrylic nplaum. Qhov no ultra-low Tg khaws PTFE high-temperature daim kab xev hloov tau yooj yim thiab nplaum txawm nyob rau ntawm -70 ° C, tiv thaiv nkig tawg thiab ua kom muaj kev ruaj ntseg adhesion hauv cov ntawv thov cryogenic.

PTFE high-temperature daim kab xev tuaj yeem tawg los yog tawg nyob rau hauv rov khoov thiab qhib tej yam kev mob. Kab lus no piav qhia yuav ua li cas tiv thaiv qhov no los ntawm kev xaiv cov substrate kom zoo (iav fiber ntau reinforced), pom thickness (0.18mm raws li tus qauv), silicone nplaum xaiv, thiab cov txheej txheem installation kom raug.

Kev xaiv ntawm cov ntawv tso tawm lossis zaj duab xis substrate thiab tso tawm tus neeg sawv cev ncaj qha cuam tshuam rau kev ruaj khov thiab kev ua haujlwm ntawm PTFE cov ntaub nplaum kub. Kab lus no sib piv PET vs. kraft daim ntawv substrates thiab silicone vs. fluorinated tso cov neeg ua haujlwm, pom zoo ua ke kom zoo rau xoom-residue tev thiab kev ntseeg tau ntev.
