Ndlela Yo Tiyisekisa Flatness ya PTFE High-Temperature Cloth Hi nkarhi wa Sintering

Sintering i goza ra nkoka laha ti particles ta PTFE ti n’okaka, ti khulukaka, naku hlangana eka filimi leyi yaka emahlweni. Kambe nakambe i xiteji lexi ku rhetela ku lahleka hi ku olova swinene. Ku tsana loku nga ringaniki, ku cinca ka mahiselo hi ku hatlisa kumbe ku nga tikhomi hi ndlela leyi ringaneke swi nga vanga swirhumbana leswi nga hundzukiki, matlhelo lama nga ni magandlati ni ku rhendzeleka loku nga lulamisiwiki endzhaku ka sweswo.

Nsinya wa nkoka wa ku hlayisa flatness i vulawuri lebyi kongomeke eka tension, temperature, na maendlelo ya restraint – leswi endlaka leswaku kuva na ku vumbiwa loku hlanganeke ka fiberglass substrate xikan’we na molten PTFE coating.

Aokai PTFE  (PTFE fiberglass cloth ) yi tumbuluxile maendlelo yo tiya ya sintering ku tiyisisa ku flatness leyi nga cincekiki. Nkongomiso lowu wu katsa ntlhanu wa tindzhawu ta nkoka ta vulawuri bya ku tiya loku tiyeke eka vuhumelerisi bya xitalo.

Ku Sivela Switirhisiwa – Muchini wa Stenter Wa Boha

Lexi i xitshunxo xa nkoka ku sivela ku hunguteka ka weft na wavy selvedges. Pin stenter (kumbe clip stenter) yifanele ku vekiwa endzeni ka sintering furnace.

1. Ku vumba hi ku tsemakanya

Ti pin plates ti tlhava makumu ya malapi. Hiku lulamisa ku anama ka track ya ti conveyor chains, ku tirhisiwa mild transverse tension – kumbe hi xiringaniso, ku anama ka lapi rosungula ku hlayisiwa kuva ku lwisana na thermal shrinkage stress ya substrate ehansi ka kuhisa lokukulu. Handle ka xipimelo lexi, ku anama ka lapi ka hunguteka naswona makumu ya va ni magandlati.

2. Vulawuri bya nkarhi wo leha

Ku hambana ka rivilo loku kongomeke exikarhi ka swirhendzevutani swa le mahlweni na swa le ndzhaku ku katsa na vulawuri bya ntshikelelo wa closed-loop swi tisa ntshikelelo wa le hansi swinene na lowu tiyeke wa longitudinal:

• Ku tsana ngopfu – swi pandzeka coating kutani swi hlohletela ku hunguteka ka post-cooling na warpage

• Ku pfumaleka ka tension – swivanga swirhumbana hiku leha (lapi 'bunches up') .

Profayile ya Mahiselo ya Sayense – Ku Hisisa hi Gradient na Ku Pfuxeta Hi Ku nonoka

Gradient curve ya ku hisa loku olovaka, ku n’oka loku heleleke, na ku kufumela hi ku nonoka swa laveka ku herisa thermal shock na stress-induced warpage.

1. Ndhawu yo kufumeta

Mahiselo ya tlakuka hiku nonoka ku rhendzela ndzhawu ya PTFE melting point (327°C) kuva yi ringanisela mahiselo yale ndzeni nale henhla ya lapi. Ku hisa ngopfu ka ndzhawu kumbe ku tlakuka ka mahiselo hiku hatlisa swi endla leswaku kuva na kuhunguteka lokunga ringaniki xikan’we naku pfimba ka nkarhi hinkwawo. Xikongomelo iku pfumelela kuhisa kuva ku nghena hindlela yin’we eka vukulu bya lapi loko kungase sungula ku n’oka hiku hetiseka.

2. Ndhawu yo khoma sintering

Mahiselo ya nkarhi hinkwawo ya hlayisiwa eka 380-400°C kuringana nkarhi lowu ringaneleke wotshama. Lexi:

• Ku n’okisa hi ku helela swiphemuphemu swa PTFE ku va filimi leyi yaka emahlweni

• Yi humesa ntshikelelo wa le ndzeni lowu saleke wa fiberglass ehansi ka xiyimo xa flat lexi siveleriweke

• Ku tiyisisa ku hlanganisiwa loku heleleke na ku tsindziyela

3. Cooling zone – yitala ku honisiwa, kambe ya nkoka swinene

Lexi i xiteji lexi warpage yi talaka ku humelela eka xona. Ku kufumela hiku nonoka swa laveka loko ku hlayisiwa stenter restraint kufikela loko mahiselo ya hunguteka ehansi ka PTFE crystallization point (kwalomu ka 310°C ).

Nawu wa nkoka: Ku kufumela ka moya hiku sindzisiwa hiku hatlisa swi endla leswaku kuva na kuhunguteka lokunga fambelaniki exikarhi ka coating na substrate – leswi endlaka leswaku kuva na persistent warping kumbe curling selvedges leyinga flattened endzhaku ka sweswo. Hlayisa lapi ri pfaleriwile kufikela loko PTFE yi crystallized hiku hetiseka naswona yi lotleriwa eka xivumbeko xa yona xohetelela.

Ku Endliwa ka Substrate Pretreatment na kufana ka ku peta

Ku phaphamala hinkarhi wa sintering swiya hi leswi humelelaka loko lapi ringa se nghena eka furnace.

1. Ku hungutiwa ka le mahlweni ka lapi ra le hansi

Loko kungase cheriwa PTFE, lapi ra fiberglass ri endla dewaxing ya mahiselo yale henhla xikan’we naku hungutiwa ka ha ri emahlweni ku susa ntshikelelo lowu saleke wa ku luka. Leswi swihunguta swinene secondary shrinkage hinkarhi wa sintering naswona swiveka masungulo ya superior flatness.

Aokai PTFE note: Handle ka pre-shrinking, fiberglass yita ringeta ku contract hi nkarhi wa sintering – ku lwisana na stenter restraint xikan’we naku vanga ku hangalasiwa ka ntshikelelo lokunga ringaniki.

2. Ku enta ka xifunengeto lexi fanaka

Leyara leyi cheriweke PTFE yifanele kuva na vukulu lebyi nga cincekiki eka lapi hinkwaro. Ku peta lokunga ringaniki swivanga nkarhi wohambana wa ku n’oka – tindzhawu to olova ti n’oka hiku hatlisa kutlula tindzhawu to tiya – leswi humesaka ti stress ripples leti fanaka na xivumbeko xa orange peel xikan’we naku onha flatness.

• Ku lawuriwa lokunene ka impregnation, ku peta blade ya dokodela, na maendlelo ya squeeze rolling i swa nkoka.

• Hambi kuri ku hambana lokuntsongo ka vukulu (0.01mm) swinga vanga swihoxo leswi vonakaka swale henhla.

Ti-Roller ta Nkongomiso wa ku Famba ka Moya na ku kongoma

1. Dizayini ya ku rhendzeleka ka moya wo hisa

Amukela top-and-bottom counter-blow kumbe uniform circulating hot air endzeni ka furnace ku papalata single-side strong airflow leyi hlaselaka hiku kongoma eka lapi – leswi endlaka leswaku kuva na swikoweto swa flutter. Nseketelo wa air cushion lowu tiyeke eka ti ovens letinga horizontal wu sivela ku rhetela ka lapi eka ti spans to leha leti lengalengaka.

2. Ku fana loku tiyeke ka swirhendzevutana

Ti guide rollers hinkwato na ti tension rollers tifanele ku hlayisa ultra-high parallelism naswona titshama ti basile handle ka masalela yo namarhela:

• Ku hambuka lokuntsongo ka malapi swi endla leswaku ku va na ku tsana loku nga ringaniki eka matlhelo hamambirhi na ku rhurhumela ka tlhelo rin’we

• Sisiteme yo lulamisa makumu ya otomatiki yi ta hlomisiwa

• Ku basisiwa nkarhi na nkarhi swi sivela ku hlengeletana ka namarheta leswi vangaka ku cinca ka tension ya ndzhawu yin’we

Nkatsakanyo – Fomula ya Xiphepherhele

Ku phaphamala loku hetisekeke a ku fikeleriwa hi matimba ya le handle yo tshikilela. Ematshan’wini ya sweswo, ehansi ka ku siveriwa ka planar loku kongomeke ka muchini wa stenter, mahiselo lawa ya fanaka na tension swi n’oka naswona swihlanganisa PTFE coating na fiberglass substrate eka xivumbeko xo olova, laha ntshikelelo hinkwawo lowu saleke wu humesiwaka hiku hetiseka hiku kufumela hakatsongotsongo.

Ku hambuka eka xihlanganisi xin’wana na xin’wana xa phurosese swita hetelela switikomba tani hi vuandlalo bya lapi lebyi nga ringaniki.

Aokai PTFE yi lawula ti parameters leti hinkwato ku tisa lapi ra PTFE leri tiyisisiweke ra flatness. Eka switirhisiwa leswi lavaka lapi ra ultra-flat (xikombiso, PCB laminating, solar laminators), hi nyika swihlawulekisi swa flatness yo tiya na maendlelo yo engetela ya flattening.

Vuxokoxoko bya xithekiniki lebyi nga laha henhla byi nyikiwa hi Jiangsu Aokai Switirhisiwa Leswintshwa Thekinoloji Co., Ltd.

Loko u lava ku dyondza swihlawulekisi leswi nga na vuxokoxoko, swiyimo swa xikombelo na swintshuxo leswi endleriweke layini ya hina ya swikumiwa leswi heleleke, ku katsa na lapi ra mahiselo ya le henhla ya PTFE, thepi yo namarhela ya mahiselo ya le henhla ya PTFE, bandi ra mesh ra mahiselo ya le henhla ya PTFE, bandi ro kandziyisa ku hisa leri nga na swirhabyani, lapi ra PTFE ra tlhelo rin’we, bandi ro fambisa leri nga tiyangiki eka mahiselo ya le henhla na fiberglass leyi nga tiyiseliki ku hisa lapi, hi kombela u hi tihlanganisa hi tichannel leti landzelaka:

• Nkulukumba Guo: +86 18944819998
