Mokhoa o Felletseng oa Tlhahiso ea Liindasteri ea PTFE Emulsion Impregnated Fiberglass Lesela

Jiangsu Aokai New Materials, moetsi oa lesela la mocheso o phahameng oa PTFE, o u isa tšebetsong e felletseng.

Lesela la PTFE le nang le mocheso o phahameng oa mocheso, ka lik'hemik'hale tse tsejoang e le polytetrafluoroethylene (PTFE) e koahetsoeng ka lesela la fiberglass , ke sesebelisoa se ikhethang sa polymer composite. Tlhahiso ea eona hase mokhoa o bonolo oa ho roala, empa ke mokhoa o rarahaneng oa phekolo ea mocheso le lik'hemik'hale. Ho hlahisa lesela le phahameng la mocheso oa PTFE, ho hlokahala mokhoa o tiileng oa mekhahlelo e mene: ho lokisoa ha lesela la motheo, ho lokisoa ha tharollo ea ho kenya letsoho, ho kenngoa ha mantlha le ho sintering, le ka mor'a phekolo..

Mothati oa 1: Phekolo ea Pele ea Lesela la Base

Mokhahlelo ona o etsa qeto ea matla a mochine le botšepehi ba sebopeho sa lesela la ho qetela la PTFE.

Thermal Cleaning (Dewaxing) Khoele ea fiberglass e sebelisetsoang ho loha lesela la PTFE e na le lisebelisoa tsa organic sizeng nakong ea tlhahiso. Haeba e sa tlosoe, mahlahana ana a sitisa ka matla ho khomarela liphahlo tse latelang tsa PTFE. Ka hona, mohato oa pele ke ho fepa lesela la motheo ka sebōping sa mocheso o phahameng (hoo e ka bang 350 ° C) bakeng sa ho phalla ka potlako ho netefatsa bohloeki ba fiberglass substrate.

Phetoho ea Bokaholimo Ho ntlafatsa matla a tlamahano lipakeng tsa fiberglass le resin ea ho roala ea PTFE, lesela la motheo le alafshoa ka silane coupling agent. Mohato ona o ntlafatsa haholo matla a lekhapetla la interlaminar mme o thibela delamination kapa ho roala letlalo ka sehlahisoa se felileng.

Mothati oa 2: Tokisetso ea PTFE Impregnation Emulsion

Lintho tsa 'mele le tsa lik'hemik'hale tsa lesela la ho qetela li khethoa haholo sethaleng sena.

· Emulsion Mixing The mantlha e tala e concentrated PTFE hasana . Ho ea ka litlhoko tse fapaneng tsa kopo - joalo ka ts'ebetso e phahameng e se nang thupa bakeng sa masela a ho baka lijo kapa khanyetso e phahameng ea ho roala masela a ho lokolloa - li-fillers le li-additives li kenngoa hantle ka har'a emulsion. Tharollo e entsoeng ea ho inregnation e bohlokoa ho hlalosa boemo ba lesela le phethiloeng la PTFE.

Mothati oa 3: Ho Imahanngoa ha Maikutlo le ho Sintering

Ena ke ts'ebetso ea bohlokoa e fanang ka lesela la PTFE ts'ebetso ea lona e ikhethang, hangata e kenyelletsang lipotoloho tse pheta-phetoang.

Multiple Impregnations Tlas'a taolo ea tsitsipano e sa khaotseng, lesela la motheo le entsoeng esale pele le feta khafetsa ka tanka ea dip e tletseng PTFE emulsion. Ho finyella botenya le boima bo lakatsehang, mohala oa tlhahiso o nka mokhoa oa cyclic: impregnation → ho omisa → sintering . Potoloho e 'ngoe le e' ngoe ka nepo e eketsa boima ba ho roala.

Ho omisa Lesela le kentsoeng ka halofo le felileng le feta ka ontong ea mocheso o tlase (hoo e ka bang 100 ° C) ho tlosa mongobo ka bonolo. Taolo e sa nepahalang mothating ona e baka habonolo li-bubble kapa li-pinholes nakong ea sintering, e senyang ts'ebetso ea insulation ka botebo.

Sintering e Phahameng ea Mocheso Sena ke pelo ea ts'ebetso ea tlhahiso. Sekoaelo se metsi se silafatsoa hoo e ka bang 380 ° C, ho lumella likaroloana tsa PTFE ho qhibiliha ka ho feletseng le ho phalla, ho etsa filimi e sireletsang e teteaneng. Bokhoni ba lesela la PTFE ho mamella ts'ebeletso ea nako e telele ho 260 ° C bo tsoa ho polymer chain recrystallization mohatong ona. Lesela le sa phethoang le sa phethoang le atisa ho phunyeha le ho lahleheloa ke thepa e sa tsitsang.

Mothati oa 4: Tlhahlobo ea Ka mor'a Phekolo le Tlhahlobo e Feletseng ea Lihlahisoa

Ka mor'a ho sintering, lesela le tsoela pele ka mekhoa e meng ea ho qetela.

Li-Hot-Press Setting le Surface Treatment Masela a phahameng a PTFE (a kang a mabanta a conveyor) a khethiloe ka li-roller tse chesang ho batalatsa bokaholimo le ho imolla khatello ea maikutlo ka hare. Bakeng sa masela a PTFE a sebelisoang ka li-laminates tsa koporo tse phahameng-frequency, kalafo e khethehileng ea corona e sebelisoa ho eketsa bohlasoa bo holimo.

Ts'ebetso ea Lamination Bakeng sa lisebelisoa tse phahameng tsa ho hloekisa, lesela le tšesaane la polytetrafluoroethylene (ePTFE) le atolositsoeng la membrane ea microporous e laminated holim'a metsi, e leng se etsang hore ho be le mochine o kopanyang o nang le bokhoni bo phahameng ba ho hloekisa.

Aokai New Materials e sebelisa tlhahlobo e tiileng ea boleng. Lihlahisoa tsa ho qetela li lekoa ho sebelisoa tlhahlobo ea grammage, tester ea high-voltage, le tester tensile. Ke lihlahisoa feela tse nang le botenya bo tšoanang, tse se nang likoti, le tse tsamaellanang le litlhoko tsa ho hanyetsa motlakase li lokolloa e le thepa e tšoanelehang.

Lintlha tse kaholimo li fanoe ke Jiangsu Aokai New Materials Technology Co., Ltd.

Bakeng sa lintlha tse qaqileng, maemo a ts'ebeliso le litharollo tse ikhethileng tsa lihlahisoa tsa rona tse felletseng - ho kenyeletsoa masela a mocheso o phahameng oa PTFE, litheipi tsa PTFE tse nang le mocheso o phahameng oa mocheso, mabanta a marang-rang a mocheso o phahameng oa PTFE, mabanta a se nang seam bakeng sa mochini oa ho kopanya, masela a mahlakoreng a le mong a PTFE, masela a nang le mocheso o phahameng oa mocheso o phahameng, lesela le nang le mocheso o phahameng oa khalase le rona:
