Fiberglass lesela thermal shrinkage ke sesosa se ka sehloohong sa PTFE tepi dimensional ho se tsitse. Ho PTFE sintering thempereichara (360-400 ° C), masala a loha khatello ea kelello e lokolloa. Haeba e sa thibeloe, lesela lea fokotseha; haeba e thibetsoe, khatello ea kelello e patehileng e koaletsoe, e bakang ho fokotseha ha morao nakong ea ho phekola ka sekhomaretsi (150-200 ° C) le ho futhumatsa ho qetela. Tharollo: sebelisa fiberglass e behiloeng pele ho mocheso e nang le <0.5% shrinkage ho 400 ° C, ho felisa khatello ea kelello e setseng pele u roala.

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.

Aokai PTFE e hlahisitse lethathamo la eona le felletseng la lihlahisoa 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.

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). Khetha ho latela taolo ea tikoloho le ts'ebetso ea nako e telele khahlano le nako e khuts'oane.

Testing PTFE emulsion boleng akarelletsa tse tšeletseng lintlha tse ka sehloohong: dikahare tiileng (60±2% ka T/FSI 067-2021), pH (9.0-11.0), phatsa boholo kabo (laser diffraction/DLS), viscosity (12-30 mPa·s ka 25°C), botsitso (centrifugal, freeze-thaw, ponahalo ea thaw. Tataiso ena e akaretsa mekhoa e tloaelehileng ea tlhahlobo bakeng sa paramethara ka 'ngoe.

Ho kenya tepi ea mocheso o phahameng oa PTFE ka tieo holim'a libaka tse kobehileng le tse sa tloaelehang ntle le li-bubble le bohale bo sothehileng, ho hlokahala ts'ebetso e tloaelehileng ea ts'ebetso, ho kenyelletsa le pretreatment e phethahetseng ea substrate, litsebo tsa kopo ea setsebi le mehato e nepahetseng ea thuso. Har'a bona, substrate pretreatment ke mohato oa bohlokoa ka ho fetisisa, o khethang hoo e ka bang 70% ea phello ea ho qetela ea ho khomarela.

Khahlanong le semelo sa melaoana e ntseng e eketseha ea tikoloho, PFOS/PFOA-free PTFE emulsion ke sehlahisoa se ntlafalitsoeng se ntlafalitsoeng ho nkela mekhoa ea setso e nang le polymerization ea PFOA. E boloka thepa ea mantlha ea PTFE ha e ntse e ntlafatsa haholo botsoalle ba tikoloho le polokeho ea bophelo bo botle.

Mocheso oa katoloso ea mocheso oa lesela la mocheso o phahameng oa PTFE hase boleng bo tsitsitseng. E lula e batla e le tlaase mocheso oa kamore ho ea ho 100 ° C (hoo e ka bang 0.5×10⁻⁵/°C), leha ho le joalo e nyoloha haholo tlas'a maemo a phahameng a mocheso.
