Ndlela leyi Ku basa ka swilo leswi nga si swekiwaka ku khumbaka ha yona matirhelo ya lapi ra mahiselo ya le henhla ya PTFE

Lapi ra PTFE ra mahiselo yale henhla (PTFE-coated fiberglass) ri kahle ntsena kufana na switirhisiwa swoka swinga tirhisiwanga ku endla. Swiphemu swimbirhi swina nkoka: PTFE resin/emulsion (ku peta) na fiberglass substrate (ku tiyisisiwa). Thyaka eka xin’wana na xin’wana – ti ions ta nsimbi, ti polymers ta molecule yale hansi, ti residual sizing agents, kumbe alkali oxides – swinga vanga ku tsandzeka ka nkarhi: ku tshwuka, ku pandzeka, ku lahlekeriwa hi non-stick, delamination, kumbe ku tshoveka ka insulation.

Aokai PTFE yi tirhisa switirhisiwa swa vutengi bya le henhla na vulawuri byo tika bya maendlelo. Nkongomiso lowu wu hlamusela hilaha ku basa ku khumbaka mpimo wun’wana na wun’wana wa matirhelo na leswaku hikokwalaho ka yini swi ri swa nkoka eka switirhisiwa leswi lavaka.

PTFE Raw Material Purity – Hi wahi thyaka leri nga kona?

Thyaka leri tolovelekeke eka PTFE ri katsa:

• Ti monomers letinga endlangiki nchumu na ti polymers ta ntiko wa molecule yale hansi

• Swisunguri swa masalela na swihangalasi (xikombiso, PFOA) .

• Ti- ion ta nsimbi (nsimbi, koporo, sodiyamu) .

• Swipfuno swo lulamisa na swikumiwa swa le tlhelo

Ku basa kale henhla swiendla leswaku switirhisiwa swikota ku tisa matirhelo ekusuhi na swihlawulekisi leswinene.

1. Ku tiya ka ku hisa na ku tiya ka ku hisa

Ti ions ta nsimbi (iron, copper, sodium) ti tirha tani hi swihlohloteri swo tiya swa PTFE thermal degradation . Ehansi ka vukorhokeri bya nkarhi woleha ehenhla ka 260°C, hambi kuri thyaka ra trace metal ri hatlisisa ku tshoveka ka molecular chain, leswi vangaka ku tshoveka ka nkarhi na ku pandzeka. PTFE ya vutengi byale henhla yina mahiselo yale henhla ya ku bola ka mahiselo, yitshama yiri yo basa, naswona yi lwisana na ku tshwuka hindlela leyinene.

2. Ku tirha loku nga namarheli na khwalithi ya le henhla

Ti polymers ta molecule yale hansi xikan’we na switirhisiwa swa mafurha swi rhurhela eka coating surface hinkarhi wa high-temperature sintering, leswi endlaka ti precipitates.

• Nhundzu leyi onhakeke leyi nga namarheliki: Vuandlalo byi hundzuka bya tacky naswona byi tala ku namarhela eka switirhisiwa leswi lulamisiweke (swakudya, ti adhesive tapes).

• Khombo ra ku thyakisa: Eka switirhisiwa swa food-grade na swa vutshunguri, ti precipitates leti rhurheriweke tinga thyakisa switirhisiwa naswona ti tsandzeka swipimelo swa vuhlayiseki. Ku basa i xikombiso xa nkoka xa malapi ya PTFE lawa ya hlanganaka na swakudya.

3. Ku tirha ka ku pfaleriwa ka gezi

Ti ions ta thyaka (metal cations, halogen ions) ti tirha tani hi ti charge carriers, leswi hungutaka swinene volume resistivity xikan’we na breakdown voltage. Eka switirhisiwa swa high-insulation (xikombiso, electrical insulating gaskets), ku basa ka raw material swina nkoka swinene. Ti pores leti vangiwaka hi thyaka tinga tlhela ti endla leswaku kuva na ku humesiwa ka xiphemu.

4. Ku lwisana na tikhemikhali na ku hlangana

Thyaka leri n’okaka ri khuluka loko ri hlangana na ti khemikhali, leswi siyaka ti micro-pores endzeni ka xifunengeto. Swihoxo leswi swipfumelela gasi leyi bola na mati kuva swi nghena naku tshoveka eka fiberglass substrate, leswi onhaka matirhelo ya xisirhelelo xa lapi.

Ku basa ka Fiberglass Substrate – Timhaka ta Nhlayo ya Alkali

Fiberglass a hi silicon dioxide leyi tengeke. Xivumbeko xa yona xa tikhemikhali xi hlamusela ku tiya ka ku hisa, matimba ya michini, na ku boha na PTFE.

1. Nhlayo ya alkali metal oxide – xivangelo xa xiboho

Eka mahiselo yale henhla, ti alkali metal ions kusuka eka nghilazi ya vutengi byale hansi ati tsani ntsena lapi hi roxe kambe titlhela ti hlohletela ku onhaka ka PTFE coating , leswi hatlisisaka ku tsandzeka hinkwako. Ku engetela kwalano, nghilazi ya medium/high-alkali yi tswonga ndzhongho, leswi endlaka leswaku ku tiya ka insulation ku hunguteka swinene.

2. Switirhisiwa swo pima – thyaka rin’wana

Switirhisiwa swo pima (starch, PVA, oil) swi cheriwa hinkarhi wa fiberglass weaving kuva swisirhelela ti fibre. Loko yinga susiwi hiku hetiseka loko kungase endliwa PTFE coating, ti organics leti saleke ti carbonize, ti bola, naswona ti gasify hinkarhi wa sintering kwalomu ka 400°C.

• Swihoxo swale henhla: Ku cinca ka muhlovo wotshuka, swivati ​​swa ntima, swirhumbana – swihumelerisiwa swi tsandzeka ku kamberiwa ka xivumbeko.

• Weak interfacial bonding: Masalela ya carbon ya sivela ti khemikhali na physical anchoring exikarhi ka PTFE na fiberglass, leswi vangaka delamination, blistering, na peeling hi nkarhi wa vukorhokeri.

3. Ku lwisana na ku karhala hi ku olova

Micro air bubbles na thyaka ra crystalline endzeni ka ti fiberglass filaments swihunguta matimba ya tensile ya ti fibre ha yin’we yin’we. Ehansi ka ku gombonyoka loku phindha-phindhiweke, swihoxo leswi swi hundzuka tindzhawu ta stress concentration, leswi vangaka ku tshoveka ka fibre ka ha ri emahlweni naswona swi hunguta swinene ku olova na vutomi bya flex.

Nkatsakanyo – Vutengi byi veka Silingi ya Matirhelo

Ku basa ka switirhisiwa swoka swinga lulamisiwanga swi veka matirhelo ya xisekelo ya malapi ya mahiselo yale henhla ya PTFE:

• PTFE ya vutengi bya le henhla yi boha: mahiselo ya le henhla ya vukorhokeri (260°C+), ku tiya ka nkarhi wo leha loku nga namarheli, ku pfaleriwa ka gezi loku tshembekaka, na ku landzelela ku hlangana na swakudya.

• Fiberglass ya vutengi byale henhla leyinga riki na alkali (E-glass, Na2O <0.8%) xikan’we na switiyisekiso swaku susiwa ka vukulu hi vukheta: matimba ya substrate eka mahiselo yale henhla, ku tiya ka dimensional, na ku namarhela loku tiyeke ka coating handle ka delamination.

Ku pfumala ku basa loku ringaneleke eka xihlanganisi xin’wana na xin’wana swita endla leswaku kuva na ku tsandzeka ka nkarhi – ku tshwuka, ku delamination, ku onhaka ka insulation, na ku lahlekeriwa hi non-stick – ngopfu ngopfu ehansi ka swiyimo swo tika: mahiselo yale henhla ya nkarhi woleha, voltage yale henhla, kumbe swilaveko swo tika swa vuhlayiseki.

Aokai PTFE yi kuma ntsena emulsion ya PTFE ya vutengi bya le henhla (ion ya nsimbi yale hansi, oligomer yale hansi) na lapi ra fiberglass ra E-glass (leyi nga riki na alkali, leyi basisiweke hiku hisa hiku hetiseka). Hi nyika switifikheti swa swilo naswona hi nga seketela switirhisiwa swa giredi ya swakudya na swa le henhla swa insulation. Tihlanganisi na hina ku kuma vuxokoxoko bya swihlawulekisi.

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

Loko u lava ku dyondza swo tala hi vuxokoxoko bya swihlawulekisi, swiyimo swa xikombelo na swintshuxo leswi endleriweke 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 PTFE, mabandhi ya muchini wo boha lama nga na swirhabyani, lapi ra PTFE ra tlhelo rin’we, mabandhi ya conveyor lama nga tiyangiki na mahiselo ya le henhla na fiberglass leyi nga tiyangiki hi mahiselo ya le henhla malapi, hi kombela u hi tihlanganisa:

• Nkulukumba Guo: +86 18944819998

• Nkulukumba Liu: +86 13705266308

Minkarhi hinkwayo hi seketela filosofi ya vutshila na vutshembeki, naswona hi tiyimiserile ku ku nyika swintshuxo swa xiyimo xin’we na vukorhokeri lebyi ehleketiweke.
