Fiberglass weave qauv - dawb, twill, los yog satin - cuam tshuam rau PTFE siab-kub ntaub ntaub. Satin weave muaj lub zog tsim kua muag siab tshaj plaws (2-3x tiaj) thiab yooj, zoo tagnrho rau dynamic dabtsi yog khoov. Plain weave muab qhov zoo tshaj plaws kev ruaj ntseg thiab tev adhesion, haum rau kev siv zoo li qub. Twill sib npaug tag nrho cov khoom siv rau kev siv dav dav.

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 conveyor siv (Teflon txoj siv sia) txhim kho cov khoom noj khoom noj los ntawm plaub qhov txiaj ntsig tseem ceeb: kev ua haujlwm tsis zoo (txo cov khib nyiab thiab nplaum), qhov kub siab ntev (-100 ° C txog 260 ° C ua rau ci kom khov), yooj yim tu thiab cov kab mob tsis zoo (tsis muaj qhov ntxeem tau, FDA ua raws), thiab kev txuag kev ua haujlwm ntev (siv lub zog qis). Haum rau cov khoom ci, khoom noj khov, chocolate, thiab cov khoom nplaum.

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.

Txheej uniformity ntawm PTFE high-temperature npuag yog txiav txim los ntawm plaub yam: txheej formulation (particle loj 0.15-0.35 μm, viscosity, khoom cov ntsiab lus), txheej & sintering txheej txheem (hla txheej nyiam rau uniformity), substrate zoo (weave qauv, pre-kho), thiab ntau lawm ib puag ncig (<20-25 ° C), Dip + hniav ua ke txheej txheem sib npaug nkag mus thiab nto smoothness.

PTFE nto kev kho mob rau kev sib khi adhesion siv ob txoj hauv kev: kub-kub melting (zoo tshaj huab cua tsis kam, 9.5 MPa lub zog nrog coupling tus neeg sawv cev, tab sis tso tawm cov pa roj carbon monoxide) thiab sodium-naphthalene etching (5 MPa tam sim adhesion, nqaim 24-48 teev lub qhov rais, pov tseg txaus ntshai). Xaiv raws li kev tswj hwm ib puag ncig thiab lub sijhawm ntev vs.

Kev tu thiab tu kom zoo txuas ntxiv lub neej ntawm PTFE high-temperature ntaub. Ntxuav tom qab siv thiab tom qab txias. Siv cov txhuam hniav mos, cov tshuaj ntxuav tes tsis huv, lossis cawv rau cov stains. Tsis txhob siv cov kua qaub/alkalis, tshuaj dawb, lossis hlau scrapers. Tsis tu ncua silicone roj lubrication txo hnav. Ua raws li cov lus qhia no txhawm rau tiv thaiv cov txheej txheem puas tsuaj.

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.

Kev ntsuas PTFE emulsion zoo suav nrog rau qhov ntsuas tseem ceeb: cov ntsiab lus khoom (60 ± 2% ib T / FSI 067-2021), pH (9.0-11.0), particle loj tis (laser diffraction / DLS), viscosity (12-30 mPa·s ntawm 25 ° C), thermal stability (freezet-zoo li, centrifugal). Phau ntawv qhia no suav nrog cov qauv kev sim rau txhua qhov ntsuas.

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 adhesive-dawb PTFE daim kab xev - yuav tsum tau. Peel lub zog poob mus txog 40% tom qab 48 teev hauv dej.
