Hobaneng ha Lesela la Glass Fiber le Tlameha ho Dewaxing Pele le Emolloa ka PTFE Emulsion? Molao-motheo ke ofe?

Joaloka moetsi ea hloahloa oa masela a mocheso o phahameng oa PTFE, Aokai New Materials e etsa kalafo e phahameng ea mocheso holim'a lesela la fiber ea khalase. Pele ho inregnation le PTFE (Polytetrafluoroethylene) emulsion, khalase faeba lesela undergoes dewaxing le degumming ho tlosa sizing mahlahana (textile auxiliaries) holim 'a faeba. Lisebelisoa tsena li sebetsa bakeng sa ho kopanya, ho tlotsa le ho sireletsa nakong ea ho taka le ho loha. Leha ho le joalo, haeba li sa tlosoe, li tla senya haholo boleng ba motsoako oa PTFE le fiber ea khalase. Melao-motheo haholo-holo ke e latelang:

1. Tlosa Lintho tse Tlase tsa Matla a Bokaholimo 'me u Ntlafatse ho Metsisa

Parafine, oli e tlotsang le likarolo tse ling tsa lisebelisoa tsa boholo ke lintho tse matla tse tlase. Haeba e bolokoa, emulsion ea PTFE (e nang le tsitsipano e tlase empa e na le litlhoko tse thata) e ke ke ea ata ka ho lekana holim'a khalase ea fiber, e bakang likoli tse kang li-craters le mahlo a litlhapi. Ka ho hloekisa mocheso o phahameng oa mocheso kapa ho hloekisa ka solvent, litšila li tlosoa 'me matla a holim'a khalase a eketseha, e leng ho nolofalletsang ho kolobisa ka ho feletseng ka PTFE.

2. Thibela Carbonization le Delamination Nakong High-Mocheso Sintering

Thempereichara ea sintering ea PTFE e holimo ho 360–380°C. Masala a parafine kapa li-adhesives tsa epoxy holim'a fiber ea khalase li tla khabone ka mocheso o phahameng joalo, li hlahise likaroloana tse ntšo kapa khase. Sena ha se silafatse feela sebaka (se amang thepa ea dielectric ka li-laminates tsa koporo tse nang le maqhubu a phahameng-frequency) empa, ka ho teba, lesela la carbonized le etsa sebopeho se fokolang, se fokotsang matla a ho kopanya pakeng tsa PTFE le fiber ea khalase le ho baka delamination ea thepa e kopantsoeng.

3. Theha Phello e Matla ea 'Mechanical Anchoring'.

Ho hloekisa boleng ba boleng bo holimo (haholo-holo mocheso oa mocheso o phahameng) ho feta 'ho hloekisa' feela. Ha lintho tsa manyolo li tlosoa, bokaholimo ba fiber ea khalase bo tsitsitse hanyane ho etsa li-micropores kapa ho pepesa lihlopha tse ngata tsa silanol (-OH). Sena se etsa hore ho be le maemo a tlamang ka mor'a moo (mohlala, phenyl silane), e lumellang PTFE ho theha litlamo tsa lik'hemik'hale kapa lintlha tsa 'mele tse nang le fiber ea khalase ka li-coupling agents - ho fetola 'ho roala' habonolo hore e be 'bonding' e tiileng.

4. Qoba ho Senyeha ha Thepa ea Interfacial Dielectric

Lits'ebetsong tse phahameng tse kang li-laminates tse nang le li-frequency le li-laminates tse nang le koporo, tse setseng tsa polar (wax, gum) li eketsa haholo tahlehelo ea dielectric tlas'a mocheso o phahameng le maqhubu a phahameng. Dewaxing le degumming e netefatsa hore motsoako oa khalase oa fiber-PTFE o boloka tahlehelo ea dielectric e tlase haholo le tahlehelo ea dielectric.

Ka kakaretso, sepheo sa mantlha sa phekolo ena ke ho felisa likarolo tse fokolang tsa li-interface le ho etsa bonnete ba hore PTFE, thepa e tlaase ea matla a holim'a metsi, e finyella ho koloba ka mokhoa o phethahetseng le ho kopanya matla a phahameng holim'a fiber e hloekileng, e phahameng ea matla a matla a holim'a metsi.
