Xivumbeko xa xiphemu xo tsemakanya xa Lapi ra PTFE ra Mahiselo ya le Henhla: Xana Ku na Leyara ya ku Cinca Exikarhi ka PTFE Coating na Fiberglass Substrate?

Jiangsu Aokai New Materials, muendli wa xiphurofexinali wa lapi ra PTFE ra mahiselo ya le henhla, u ku tisela vutivi lebyi dzikeke. Tanihi xitirhisiwa xa xivumbeko xa matirhelo yale henhla, xivumbeko xa microscopic cross-sectional xa PTFE high-temperature cloth i swa nkoka swinene eka ku tiya ka yona ka mahiselo, ku tiya ka peel xikan’we naku olova. Eka maendlelo ya vuhumelerisi bya lapi ra mahiselo yale henhla ya PTFE, kuna leyara  ya nkoka ya ku cinca exikarhi ka PTFE coating na fiberglass substrate. Handle ka leyara leyi ya ku cinca, vutshembeki bya xivumbeko lebyi hlanganisiweke bya lapi ra mahiselo yale henhla ya PTFE a byi nge fikeleleki.

Hiku tirhisa cross-sectional microscopic analysis, leyara leyi ya ku cinca ayi vumbiwanga hi nchumu wun’we wa tikhemikhali, kambe i ndzhawu ya interfacial leyi hlanganisiweke leyi akiweke hiku tirhisa tindlela to tala to cinca physical na ti khemikhali. Ndlela yo vumbiwa na xivumbeko xa leyara ya ku cinca swi hlamuseriwile hi vuxokoxoko hi ndlela leyi landzelaka:

1. Leyara yo Boha ya Xiaki xa Xihlanganisi xa Silane

Fiberglass leyinga tshunguriwangiki ayi koti ku boha hiku kongoma na PTFE resin. Hikokwalaho, lapi ra fiberglass rifanele ku cinciwa hi ti silane coupling agents eka vuhumelerisi. Makumu yan’wana ya coupling agent ya endla ti khemikhali na mintlawa ya silanol (Si-OH) eka vuandlalo bya fiberglass, kasi makumu yan’wana yana mintlawa leyi tirhaka leyingana affinity yale henhla kumbe reactivity eka fluororesins. Ku tirha tani hi buloho ro hlanganisa ti khemikhali exikarhi ka fiberglass skeleton na PTFE coating, leyara leyi yinyika xisekelo xa tikhemikhali anchorage eka lamination ya xivumbeko hinkwaxo.

2. Leyara ya le Xikarhi ya Xinamarheti xa Hot-Melt

Eka ku langutiwa ka xiphemu xo tsemakanya xa lapi ra xiyimo xale henhla ra PTFE ra mahiselo yale henhla, gradient transition layer leyingana PFA (Perfluoroalkoxy alkane) kumbe FEP (Fluorinated Ethylene Propylene) yinga voniwa kahle exikarhi ka PTFE coating na fiberglass substrate. Hi nkarhi wa high-temperature sintering, ti meltable fluoroplastics leti ti tirha tani hi ti hot-melt adhesives tale ndzeni, ti nghena naku phutsela ti fiberglass bundles kuva ti endla xiphemu lexi yaka emahlweni. Leyara leyi yale xikarhi yi sivela kahle coating delamination ehansi ka swiyimo swo phindha-phindha swo gombonyoka na ku flexing.

3. Xihlanganisi xa Michini xo Hlanganisa

Lapi ra PTFE ra mahiselo yale henhla ri endliwa hiku tirhisa maendlelo yotala ya impregnation na coating. Hi microscope, PTFE emulsion yi nghena eka ti pores ta micron-sized leti vumbiweke hi warp na weft weaving ya malapi ya fiberglass. Endzhaku ka sintering naku horisiwa, resin ya PTFE leyi tiyeke yi endla xivumbeko xa michini xa three-dimensional anchoring na lapi ra fibre. Xivumbeko lexi xa ku hlanganisa xa xiviri xi tisa nseketelo wa michini lowu tshembekaka, ku tiyisisa ku tshamiseka ka tidimenxini na matirhelo ya anti-delamination eka vukorhokeri bya nkarhi wo leha.

4. Xihlanganisi xa Buffer ya Gradient

PTFE coating na fiberglass swina ti coefficients to hambana swinene ta thermal expansion, leswi hiku olova swi hlohletelaka ntshikelelo wale ndzeni ehansi ka swirhendzevutani swo hatlisa swo hisa na ku kufumela. Lapi ra premium PTFE ra mahiselo yale henhla ri amukela xivumbeko xa compositional gradient: ndzhawu leyi nga ekusuhi na fiberglass yi fuwile hi swinamarheti leswi nga hisiki na FEP, kasi ku basa ka PTFE ku tlakuka hakatsongotsongo kuya eka vuandlalo byale handle. Xivumbeko lexi xa gradient xi buffers thermal stress ehansi ka swiyimo swa mahiselo yale henhla naswona xi papalata ku pandzeka ka le henhla ka coating.

5. Xihlanganisi xa Vutshunguri bya le Mahlweni bya Substrate

Loko kungase akiwa ti transition layers letinga laha henhla, lapi ra fiberglass rifanele kuva ri endliwa high-temperature dewaxing xikan’we na desizing kuva ku susiwa switirhisiwa swo pimisa swiambalo na thyaka. Goza leri ra core pretreatment ri paluxa mintlawa ya silanol leyi tirhaka eka swiphemu swa fibre, leswi nyikaka interface leyi tengeke na leyi tirhaka hi tikhemikhali eka vutshunguri bya coupling lebyi landzelaka na ku nghena ka resin.

Xivumbeko xa xiphemu xo tsemakanya xa lapi ra mahiselo yale henhla ya PTFE xi vumba sisiteme leyi heleleke ya xivumbeko lexi kombisiweke hi ku hlanganisiwa loku tiyeke, ku nghena ka gradient na pure resin functional surface . Ku vuyeriwa eka swiphemu swa ku cinca leswi tirhaka swinene leswi hlanganisiweke hi ku pfaleka ka nyama na ku hlanganisiwa ka tikhemikhali, nchumu lowu wu hlayisa nhundzu ya kahle swinene yo humesa na ku lwisana na ku bola ka PTFE, loko wu ri karhi wu kuma matimba yo hlamarisa ya ku tsana na ku lwisana na ku karhala.

Leswi nga laha henhla swi nyikiwile hi Jiangsu Aokai New Material Technology Co., Ltd.

Hi nyika nxaxamelo lowu heleleke wa switirhisiwa ku katsa na lapi ra mahiselo ya le henhla ya PTFE, thepi ya mahiselo ya le henhla ya PTFE, bandi ra mesh ra mahiselo ya le henhla ra PTFE, bandi ra muchini ro hlanganisa leri nga riki na swirhabyani, lapi leri pfanganisiweke na PTFE ra tlhelo rin’we, bandi ro fambisa leri nga tiyangiki eka mahiselo ya le henhla na lapi ra fiberglass leri tiyiselaka mahiselo ya le henhla. Ku kuma vuxokoxoko bya tipharamitha ta swikumiwa, swintshuxo swa matirhiselo na vukorhokeri lebyi endleriweke wena, hi kombela u hi tihlanganisa:
