Anti-static PTFE lesela le fihlellwa ka mekhoa e 'meli e meholo: ho roala doping (ho kopanya li-fillers tse tsamaisang tse kang carbon black ho emulsion ea PTFE, ho etsa marang-rang a percolation nakong ea mahloriso a bohlokoa) le substrate weaving (ho kenya likhoele tsa conductive ka har'a lesela la fiberglass). Ho hanyetsa ha sefahleho ho laoloa ho 10⁵–10⁹ Ω. Molao-motheo: theha tsela ea conductive e ntšang litefello tse tsitsitseng hang-hang, ho thibela ho bokellana ho kotsi. Ho beha fatše hoa hlokahala bakeng sa ts'ebetso e sebetsang.

Li-thickeners tsa emulsion ea PTFE li sebetsa mesebetsi e mene ea bohlokoa: ho tsitsisa ho emisa (ho thibela ho lokisoa ha likaroloana tse teteaneng tsa PTFE), boits'oaro bo fokolang ba li-shear (viscosity e phahameng ha u phomotse, e tlaase tlas'a ho ferekanngoa bakeng sa ho roala habonolo), ho laola botebo ba ho kenella (ho laola ho kenngoa ha resin holim'a lesela la fiberglass), le ho tšoana ha filimi (e thibela ho phatloha nakong ea ho omisa). Tlhokahalo ea bohlokoa: li-thickeners li tlameha ho bola ka botlalo ho ~ 380 ° C mocheso oa sintering, li siee masala a molora ho boloka bohloeki ba ho roala le ho koala motlakase.

Lesela la PTFE le nang le mocheso o phahameng oa mocheso (PTFE-coated fiberglass) le fana ka khanyetso e ikhethang ea lik'hemik'hale, e mamellang concentrated acids (ho kenyeletsoa le aqua regia), li-alkali tse matla (mocheso oa kamore), li-solvents le li-oxidizing agents. Mekhelo: tšepe ea alkali e qhibilihisitsoeng le metsoako ea halogen ea mocheso o phahameng e hlasela PTFE. Tšenyo ea ho roala e pepesetsa fiberglass ho hydrofluoric acid le alkalis e chesang haholo. Mocheso o ka holimo ho 260 ° C o fokotsa ho hanyetsa. Bakeng sa libaka tse ngata tsa lik'hemik'hale, lesela la PTFE le lula le tsitsitse ebile le tšepahala.

Theipi ea PTFE ea mocheso o pharaletseng e hloka silicone PSA e bolokang ho khomarela ho tloha -70°C ho isa ho 260°C. Lintlha tse ka sehloohong tsa moralo: primer-anchored transition layer (thibela delamination), sea-island microstructure (MQ resin Islands + polysiloxane continuous phase), gradient crosslinking (high-density inner layer for creep resistance, low-density out layer for low-temp tack), le heat-stabilized fillers (cerium resistance oxide). Phenyl-modified siloxane likarolo li hatella mocheso o tlase oa crystallization, o nolofalletsang ho fetoha ha maemo ka tlase ho -100 ° C.

Aokai PTFE e hlahisitse lethathamo la eona la lihlahisoa tse felletseng ho APFE Shanghai 2026 (Booth 6T602, Hall 6). Lihlahisoa tse hlahisoang li kenyelletsa litheipi tsa PTFE tse matlafalitsoeng ka fiberglass, lifilimi tse hloekileng tsa PTFE, limaraka tse khahlanong le maemo, le mabanta a tsamaisang mocheso o phahameng - a koahelang phepelo ea lijo, PV lamination, libeteri tsa lithium, lisebelisoa tsa elektroniki le liphutheloana. Pontšo e tsoela pele ka June 26. Lihlahisoa tsohle li tšehetsa litlhaloso tsa tloaelo.

Matla a phahameng a PTFE lesela la mocheso o phahameng oa mocheso ke motsoako oa fiberglass e phahameng ea tenacity le PTFE coating. Lisebelisoa tsa bohlokoa tse tsamaisang indasteri (ho baka lijo, ho omisa masela, lipalangoang tsa PCB), ts'ireletso ea welding (sekoaelo sa mocheso-sealer, lithebe tsa spatter), ho theola le ho etsa mochini oa khatiso o chesang (ho bopa rabara, PV lamination), insulation ea motlakase (motor slot liners, wraps cable), membrane ea meralo (marulelo a lebala la lipapali, lilemo tse 30 tsa li-anti-corrosion) aerospace (likobo tsa mocheso), le lisebelisoa tse khethehileng (ho itšeha ka laser, khatiso ea 3D).

Ho omisa ke mohato oa bohlokoa oa tlhahiso ea lesela la mocheso o phahameng oa PTFE. Litšitiso tse tloaelehileng li kenyelletsa: ho petsoha (ho omisa ka potlako haholo, letlalo la letlalo), ho falla ha letlalo (likaroloana li falla holimo, tlamahano e fokolang ea ka hare), li-pinholes / li-blister (moea o koaletsoeng kapa mouoane), matheba a masoeu le ho chalking (ho falla ha surfactant kapa fusion e sa fellang), yellowing / coking (ho futhumala ho feteletseng ha li-additives), delamination (lekhapetla la lamunu), khatello ea kelello e feta (lekhapetla la lamunu). shrinkage), bokaholimo bo omileng empa kahare bo le metsi (ho holoha letlalo ho ts'oara mongobo), le mats'oafo a teteaneng (phello ea kofi). Litharollo li kenyelletsa lintlha tse laoloang tsa ho omisa, moea o nepahetseng, le pretreatment ea substrate.

Sebopeho sa sefahleho se sehiloeng sa tepi ea mocheso o phahameng oa PTFE se ama ka ho toba sekhomaretsi le ho phahamisa bohale nakong ea kopo. Ho petsoha ho fosahetseng (mahare a lerootho, angle e sa nepahalang) ho etsa likhoele tsa sekhomaretsi, ho tšesaane lera la sekhomaretsi, 'me ho pepese metsu ea khalase ea fiberglass - e lebisang ho putlama, ho fokola ho tlamahaneng le ho phahamisa mocheso kapa tsitsipano. Lifahleho tse sa tloaelehang tsa ho qetela (li-wavy, tse hlahelletseng) li baka khatello e sa lekaneng ea khatello, ho khanna sekhomaretsi nakong ea polokelo. Sefahleho se loketseng sa ho qetela se boreleli, se phunya, 'me ha se na tšenyo - se sebetsa joalo ka tiiso e notlelang sekhomaretsi le ho tiisa hore ho tlamahane ka botlalo.

PTFE emulsion impregnation ea fiberglass lesela hloka bathusi ba fapa-fapaneng ho finyella ho roala junifomo, ho khomarela ka matla, le bokaholimo bo se nang sekoli. Li-additives tsa bohlokoa li kenyelletsa: lisebelisoa tsa ho kolobisa (fokotsa tsitsipano ea holim'a metsi, ho ntlafatsa ho kenella ka hare), li-thickeners (taolo ea viscosity le boima ba ho roala), balaoli ba pH (ho tsitsisa emulsion ho pH 9-10), li-silane coupling agents (ho matlafatsa ho khomarela likhalase), lithuso tsa ho etsa filimi (PFA / FEP bakeng sa sintering), li-fillers tse sebetsang (ho thibela li-pifonholes le li-conductivity).
