Lisebelisoa tsa ho qeta holim'a metsi tse sebelisoang lesela la fiberglass pele ho roala ha PTFE li bohlokoa bakeng sa ts'ebetso ea ho qetela ea lesela la mocheso o phahameng oa PTFE. Organosilane coupling agents e theha marokho a limolek'hule pakeng tsa fiber ea inorganic glass le PTFE ea tlhaho, e matlafatsang matla a peel ho tloha ho <2 N/cm ho isa ho 4-8+ N/cm. Kalafo e nepahetseng e boetse e matlafatsa ho hanyetsa mocheso (260 ° C +), tshebetso ea dielectric, le lik'hemik'hale tse hanyetsanang le lik'hemik'hale. Lesela le sa phekoloeng le lebisa ho delamination, ho phatloha le bophelo bo khutšoanyane ba tšebeletso.

Boima ba lesela la fiberglass bo tiisa hore PTFE e sebetsa ka mocheso o phahameng oa mocheso. Boima bo phahameng bo eketsa matla a tsitsipano le boreleli bo holim'a metsi empa bo fokotsa matla a ho taboha (inverted U-curve), ho tenyetseha, le ho kenella ka hare. Tekano e nepahetseng e leka-lekanya ho kenella, ho hanyetsa meokho, ho tenyetseha le ho fella ka holimo. Boima bo tlase bo lumellana le ho kobeha ho matla; boima bo boholo bakeng sa ho se thunye le ho kenya letsoho.

PTFE substrate e hanela ho fafatsa letsoai ka tlhaho (ho monya metsi <0.01%). Leha ho le joalo, ts'ebetso ea theipi ka kakaretso e itšetlehile ka mofuta oa sekhomaretsi: silicone PSA e mamella maemo a leoatle (liteko tsa 500-1000h letsoai la spray,> 80% ho boloka lekhapetla); acrylic PSA e hloleha. Phekolo e nepahetseng ea holim'a metsi, kopo e se nang li-bubble, le ho tiisoa ka bohale ka silicone sealant ke tsa bohlokoa bakeng sa ho tšepahala ha nako e telele liforomong le likepeng tse lebōpong la leoatle.

Calendering - ho hatella lesela le koahetsoeng ke PTFE pakeng tsa lirolara tsa seipone tse futhumetseng ka 360-380 ° C - ho fetola ka mokhoa o makatsang sebopeho sa bokaholimo, thepa ea ho lokolla, ho se khonehe, le ts'ebetso ea mochini. E fokotsa boima ho tloha ho Ra 0.5-1.0 μm ho <0.05 μm, e tiisa li-pinholes, e ntlafatsa ho hanyetsa ho apara, empa e fokotsa matla a ho taboha le ho feto-fetoha ha maemo. E bohlokoa bakeng sa li-liner tse lokollang le ho kenya motlakase.

Fiberglass weave pattern - plain, twill, kapa satin - e ama haholo PTFE thepa ea lesela la mocheso o phahameng oa mocheso. Satin weave e fana ka matla a phahameng ka ho fetisisa a ho tabola (2-3x thota) le ho tenyetseha, e loketseng ho kobeha ho matla. Plain weave e fana ka botsitso bo botle ka ho fetesisa le ho khomarela lekhapetla, e loketseng lits'ebetso tse sa fetoheng. Twill e leka-lekanya thepa eohle bakeng sa tšebeliso e akaretsang.

Theipi ea fiberglass ea PTFE e hloka litifikeiti tse tharo tsa bohlokoa tsa polokeho: UL (polokeho ea motlakase le lelakabe), FDA (ho latela melao ea lijo), le ISO 9001:2015 (taolo ea boleng). Litheipi tse netefalitsoeng li fana ka ts'ebetso e ts'oanang, bophelo bo bolelele ba ts'ebeletso, le litšenyehelo tse tlase tsa beng ho sa tsotelehe litšenyehelo tse holimo tsa pele. Kamehla netefatsa litifikeiti ka kotloloho le mekhatlo e fanang ka thepa.

PTFE mabanta conveyor (Teflon mabanta) ntlafatsa mekhoa ea ho lokisa lijo ka melemo e mene ea bohlokoa: tshebetso e phahameng e sa thupeng (e fokotsa litšila le ho khomarela), mamello e pharaletseng ea mocheso (-100 ° C ho 260 ° C e nolofalletsa ho baka ho bata), ho hloekisa habonolo le ho hanyetsa likokoana-hloko (e se nang porous holim'a metsi, FDA e lumellanang le matla a nako e telele), le tšebeliso ea nako e telele ea matla a ho sebetsa. E loketse lintho tse besitsoeng, lijo tse hatselitsoeng, chokolete le lihlahisoa tse khomarelang.

Theipi ea mocheso o phahameng oa PTFE e sebelisoa likarolong tse tharo tsa ts'ebeliso ea bongaka: ts'ireletso ea thepa ea ho thibela likokoana-hloko (literei tsa autoclave, pakete ea mocheso), phekolo ea holim'a lisebelisoa (sekontiri se tlaase, motlakase), le lisebelisoa tse kenngoeng (li-vascular grafts, sutures). Biocompatibility e netefatsoa ka ISO 10993, mme FDA 21 CFR 177.1550 e theha polokeho ea thepa ea motheo.

Ho roala ho tšoana ha lesela la PTFE mocheso o phahameng ho khethoa ke lintlha tse 'nè: sebopeho sa ho roala (saese ea boholo ba 0.15-0.35 μm, viscosity, dikahare tse tiileng), mokhoa oa ho roala le oa sintering (ho roala ka lehare ho khethoa bakeng sa ho lumellana), boleng ba substrate (paterone ea weave, pele ho phekolo), le tikoloho ea tlhahiso (20-25% R <60%). Dip + blade e kopantseng ts'ebetso e leka-lekanya ho kenella le ho boreleli holim'a metsi.

Phekolo ea holim'a PTFE bakeng sa ho khomarela bonding e sebelisa mekhoa e 'meli e meholo: ho qhibiliha ha mocheso o phahameng (ho hanyetsa boemo ba leholimo bo phahameng, matla a 9.5 MPa a nang le coupling agent, empa e ntša likhase tse chefo) le sodium-naphthalene etching (5 MPa hang-hang adhesion, e moqotetsane 24-48 hora fensetere, litšila tse kotsi).
