Endlelo leri heleleke ra Vuhumelerisi bya Tiindasitiri ra PTFE Emulsion Impregnated Fiberglass Cloth

Jiangsu Aokai New Materials, muendli wa malapi ya mahiselo ya le henhla ya PTFE, u ku yisa eka endlelo leri heleleke.

PTFE lapi ra mahiselo yale henhla, hi tikhemikhali leri tivekaka tani hi polytetrafluoroethylene (PTFE) coated fiberglass cloth , i xitirhisiwa xo hlawuleka xa polymer composite. Ku endliwa ka yona ahi endlelo ro olova ro peta, kambe i endlelo ro rharhangana ra vutshunguri bya ku hisa na tikhemikhali. Ku humelerisa lapi ra xiyimo xale henhla ra PTFE ra mahiselo yale henhla, endlelo ro tika ra switeji swa mune ra laveka: ku lulamisiwa ka lapi ra base, ku lulamisiwa ka impregnation solution, core impregnation na sintering, na endzhaku ka vutshunguri.

Xiyenge xa ​​1: Ku tshunguriwa ka le mahlweni ka Lapi ra le Hansi

Xiyenge lexi xi boha matimba ya michini na vutshembeki bya xivumbeko xa lapi ro hetelela ra PTFE.

Thermal Cleaning (Dewaxing) Fiberglass yarn leyi tirhisiwaka ku luka lapi ra PTFE yina ti organic sizing agents hinkarhi wa vumaki. Loko swinga susiwi, switirhisiwa leswi swi sivela swinene ku namarhela ka swifunengeto swa PTFE leswi landzelaka. Hikokwalaho, goza rosungula iku phamela lapi ra base eka furnace ya mahiselo yale henhla (kwalomu ka 350°C) kuva yi hatlisa ku dewaxing ku tiyisisa ku basa ka fiberglass substrate.

Ku Cinciwa ka Vuandlalo Ku antswisa matimba ya bonding exikarhi ka fiberglass na PTFE coating resin, lapi ra le hansi ri tshunguriwa hi silane coupling agent. Goza leri ri tlakusa swinene matimba ya interlaminar peel naswona ri sivela delamination kumbe coating peeling eka xitirhisiwa lexi hetiweke.

Xiyenge xa ​​2: Ku lulamisiwa ka PTFE Impregnation Emulsion

Swihlawulekisi swa physical na ti khemikhali ta lapi rohetelela swikumiwa ngopfu eka xiteji lexi.

· Ku hlanganisiwa ka Emulsion Nchumu wo ka wu nga tirhisiwanga wa nkoka i ku hangalasiwa ka PTFE loku hlanganisiweke . Kuya hi swilaveko swohambana hambana swa matirhiselo — kufana na matirhelo yale henhla ya non-stick eka malapi yo baka swakudya kumbe ku tiya ka le henhla ka ku onhaka eka malapi yo humesa — ti fillers nati additives ti cheriwa kahle eka emulsion. Nkatsakanyo wa impregnation lowu endliweke wuna nkoka swinene eka ku hlamusela giredi ya lapi ra PTFE leri hetiweke.

Xiyenge xa ​​3: Ku cheriwa ka Core Impregnation na Sintering

Leri i endlelo ra nkoka leri nyikaka lapi ra PTFE matirhelo ya rona yo hlawuleka, hi ntolovelo ri katsa swirhendzevutani leswi phindha-phindhiweke.

Multiple Impregnations Ehansi ka vulawuri bya tension nkarhi hinkwawo, lapi ra base leri tshunguriweke ka ha ri emahlweni ri hundza hi ku phindha-phindha eka thangi ra dip leri taleke hi PTFE emulsion. Ku fikelela vukulu lebyi lavekaka na ku tsindziyela, layini ya vuhumelerisi yi amukela endlelo ra xirhendzevutani: impregnation → drying → sintering . Xirhendzevutani xin’wana na xin’wana xi engetela kahle ntiko wa xifunengeto.

Ku omisa Lapi leri cheriweke semi-finished ri hundza eka oven ya mahiselo yale hansi (kwalomu ka 100°C) kuva yi susa ndzhongho hiku olova. Ku lawula lokunga fanelangiki eka xiteji lexi hiku olova swivanga ti bubbles kumbe ti pinholes hinkarhi wa sintering, leswi onhaka swinene matirhelo ya insulation.

High-Temperature Sintering Leyi i mbilu ya maendlelo ya vumaki. Wet coating yi sintered eka kwalomu ka 380°C, leswi pfumelelaka ti PTFE particles kuva ti n’oka hiku hetiseka naku khuluka, leswi endlaka dense protective film. Vuswikoti bya lapi ra PTFE ku tiyisela vukorhokeri bya nkarhi woleha eka 260°C byi huma eka polymer chain recrystallization eka goza leri. Lapi leri nga sintered hiku hetiseka ritala ku pandzeka naku lahlekeriwa hi swivumbeko leswinga namarheli.

Xiyenge xa ​​4: Endzhaku ka Vutshunguri na Ku Kamberiwa ka Swikumiwa leswi Hetiweke

Endzhaku ko sintering, lapi ri hundza eka maendlelo man’wana yo hetisa.

Hot-Press Setting na Surface Treatment Malapi ya xiyimo xale henhla ya PTFE (kufana na lawa yanga eka conveyor belts) ya calendered hiku tirhisa ti hot rollers kuva yi flatten surface xikan’we naku hunguta ntshikelelo wale ndzeni. Eka malapi ya PTFE lawa ya tirhisiwaka eka ti high-frequency copper-clad laminates, vutshunguri byo hlawuleka bya corona byi tirhisiwa ku engetela ku khwaxa ka le henhla.

Endlelo ra Lamination Eka switirhisiwa swa xiyimo xale henhla swa filtration, leyara yo olova ya expanded polytetrafluoroethylene (ePTFE) microporous membrane yi laminated ehenhla ka misava, leswi endlaka leswaku kuva na composite filter medium leyingana vukorhokeri byale henhla bya filtration.

Aokai New Materials yi tirhisa ku kamberiwa loku tiyeke ka khwalithi. Swikumiwa swo hetelela swi kamberiwa hi ku tirhisa xikambelo xa grammage, xikambelo xa voltage ya le henhla, na xikambelo xa ku tsana. I switirhisiwa ntsena leswingana vukulu lebyi fanaka, leswinga riki na ti pinholes, naswona swilandzelelaka swilaveko swa voltage resistance leswi humesiwaka tani hi nhundzu leyi faneleke.

Rungula leri nga laha henhla ri nyikiwile hi Jiangsu Aokai New Materials Technology Co., Ltd.

Ku kuma swihlawulekisi leswi nga na vuxokoxoko, swiyimo swa xikombelo na swintshuxo leswi endleriweke ku tirhisiwa hi ku landza swilaveko swa nxaxamelo wa hina hinkwawo wa swikumiwa — ku katsa na malapi ya mahiselo ya le henhla ya PTFE, tithepi ta mahiselo ya le henhla ya PTFE, mabandhi ya mesh ya mahiselo ya le henhla ya PTFE, mabandhi lama nga na swirhabyani ya michini yo kandziyisa ya fusing, malapi ya PTFE ya tlhelo rin’we, mabandhi ya conveyor lama lwisanaka na mahiselo ya le henhla, fiberglass ya mahiselo ya le henhla malapi na swin’wana — hi kombela u hi tihlanganisa:
