Swipfuno swa PTFE Coated Fiberglass Fabric tani hi Nchumu wo Pfala vs. Switirhisiwa swa Ndhavuko swo Pfala swa Mahiselo yale henhla (Asbestos, Graphite) .

Jiangsu Aokai New Materials Co., Ltd., muendli wa xiphurofexinali wa lapi ra fiberglass leri pfanganisiweke na PTFE, u hlamusela swipfuno hi ndlela leyi landzelaka:

I. Nsirhelelo wa Ntivo-mbango & Vuhlayiseki: Matimba lamakulu ya PTFE Coated Fiberglass Fabric

Lapi ra fiberglass leri pfanganisiweke na PTFE ri khome swipfuno leswikulu eka mbango compliance.A yi tirhi hi tikhemikhali, a yi na chefu, a yi nun’hweli naswona a yi humesi ntshuri wa fibre. Yi nga fikelela xitifikheti xa FDA xa ku hlangana na swakudya na ku landzelela swiletelo swa mbango swa RoHS 2.0. Hikwalaho ka xivangelo lexi, i nchumu lowu rhandzekaka lowu nga kanetiwiki wo pfalela eka switirhisiwa swa le kamareni ro basa eka ku lulamisiwa ka swakudya, switirhisiwa swa vutshunguri, switirhisiwa swa mirhi, na tiindasitiri tin’wana leti nga na nkoka wa vuhlayiseki. Ku endliwa ka yona, ku tirhisiwa ni ku lahliwa ka yona hinkwaswo swi hlayisekile eka vanhu ni le ka mbango.

Kuhambana swinene, ti fibre ta asbestos i carcinogen leyi tiyisisiweke ya Group 1, khombo leri dlayaka leri papalatiwaka hiku hetiseka hi lapi leri pfanganisiweke na PTFE.Hambi leswi graphite yingariki na chefu, ya brittle, ya tiya, naswona yitala ku tshoveka naku khuluka. Xivumbeko xa xiviri lexi olovaka, lexi tengeke xa lapi leri pfanganisiweke na PTFE xi tlakukile swinene eka tindzhawu letinga basa swinene.

II. Nxopaxopo wa ku Tiyisela Mahiselo: Ndhawu yo Tirha leyi kongomeke na Swipimelo

Lapi ra fiberglass leri pfanganisiweke na PTFE ri na swipimelo swa xithekiniki leswi nga erivaleni swa ku tiya ka mahiselo:

· Mahiselo ya ntirho lawa ya yaka emahlweni: -70°C kuya eka 360°C

· Ku tiya ka nkarhi wo koma eka mahiselo yale henhla ya ku khumbeka: kuya fika eka 400°C

Endzeni ka nxaxamelo lowu, yi hlayisa ku tshamiseka ka kahle swinene ka dimensional, kungari na ku lahlekeriwa lokukulu ka matimba kumbe carbonization.Eka switirhisiwa leswingana mahiselo ya nkarhi woleha lawa ya tiyeke ehansi ka 360°C, PTFE coated fabric i ndlela ya kahle swinene eka asbestos.

Xipimelo xa yona lexikulu i mpimo wa mahiselo yale henhla yale hansi swinene.Loko mahiselo yo tirha ya tlula 360°C ehansi ka ntshikelelo lowu yaka emahlweni, creep naku olova swita humelela.Loko ku pimanyisiwa na asbestos (ku lwisana na kuhisa kuya fika eka 550°C) na graphite (kufika eka 1600°C eka inert atmosphere), lapi leri funengetiweke hi PTFE ari ringanelanga  eka switirhisiwa swa ultra-high-temperature yotala swinene swofana na tinyangwa ta boiler, ti duct ta gasi ya flue ta mahiselo yale henhla, kumbe ku pakiwa ka valve ya mahiselo yale henhla.Ku hlawuriwa kufanele ku tiyisisa hiku hetiseka leswaku mahiselo ya vukorhokeri aya hundzi nhlayo ya wona ya ku cinca ka nghilazi.

III. Seal Performance & Chemical Inertness: Banga ra Matlhelo Mambirhi

Ehansi ka swiyimo leswi faneleke swa ntirho, lapi ra fiberglass leri pfanganisiweke na PTFE ri tisa ku pfariwa loku lavaka ku hetiseka performance.Yi na xivumbeko xa le hansi swinene xa surface friction coefficient (kwalomu ka 0.05–0.1) na swivumbeko swa kahle swinene leswi nga namarheli.Leswi swi vula leswaku a yi nge namarheli kumbe ku rhuketela swiphemu swa flange ya nsimbi hi nkarhi wa ku vekiwa, leswi endlaka leswaku ku hahlula swi olova swinene.

Xa nkoka swinene, yi lwisana na ku bola kusuka eka kwalomu ka ti acid hinkwato leti tiyeke, ti alkali to tiya na organic solvents.Eka tiphayiphi ta ntshikelelo wa le hansi leti khomaka swihalaki leswi onhaka swinene, i lapi leri pfanganisiweke na PTFE ntsena leri nga tiyisisaka hi nkarhi wun’we zero permeation na vutomi byo leha bya ntirho — vuyelo byo hlawuleka lebyi nga ringanisiwiki na asbestos kumbe graphite.

Hambiswiritano, swipimelo swa yona swo pfalela na swona i swa nkoka:Lapi leri pfanganisiweke na PTFE ri na swivumbeko swo biha swinene swa anti-creep na ku tiya ka ntshikelelo loku nga nyawuriki.Ehansi ka ku layicha ka boluti ya le henhla loku nga heriki (xikombiso, ku tlula 15 MPa), ri hundza eka ku khuluka ka pulasitiki hi ku nonoka, ku hunguta ntshikelelo wo pfalela naswona eku heteleleni ri vanga ku vupfa.Hikokwalaho, eka swiyimo swa mahiselo ya le henhla na ntshikelelo wa le henhla wa petrochemical refining scenarios, hi ntolovelo ayi koti ku siva ti flexible graphite composite gaskets hi resilience yale henhla.Ku tirhisiwa hiku sindzisiwa eka high-pressure steam sealing swinga endla leswaku seal yi tsandzeka hiku olova.

Ku Hlawula Swilo Mahetelelo

Switirhisiwa leswi tsakeriwaka eka lapi ra fiberglass leri pfanganisiweke na PTFE: Mahiselo yale hansi kuya eka yale xikarhi (<360°C), ntshikelelo wale xikarhi kuya eka ehansi, switirhisiwa leswinga onhaka swinene, swilaveko swa vuhlayiseki bya giredi ya swakudya/vutshunguri.

Switirhisiwa leswi faneleke ku papalatiwa: Ku tiya ka mahiselo yale henhla swinene (>360°C), swiyimo swa ntshikelelo wale henhla swinene, ku tata swivandla leswi lavaka ku tiyisela ka swilo swale henhla eka ku hakeriwa ka deformation.

Nkomiso

Lapi ra fiberglass leri pfanganisiweke na PTFE a hi nchumu wa swikongomelo hinkwaswo, kambe endzeni ka mahiselo na ntshikelelo wa rona lowu faneleke, ri tlula swinene asbestos ya ndhavuko na graphite eka matirhelo ya mbango na ku lwisana na ku bola.Ku twisisa swipimelo swa yona swa matirhelo i xilotlelo xo kurisa nkoka wa rona wo pfalela.

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

Ku kuma vuxokoxoko bya tipharamitha, swiyimo swa xikombelo na swintshuxo leswi endleriweke nxaxamelo wa hina hinkwawo wa swikumiwa — ku katsa na lapi ra fiberglass leri funengetiweke hi PTFE, thepi ya mahiselo ya le henhla ya PTFE, mabandhi yo fambisa ya mesh leyi pfulekeke ya PTFE, mabandhi ya muchini wo fuwa lama nga riki na swirhabyani, lapi ra PTFE ra tlhelo rin’we, mabandhi yo fambisa lama nga ni mahiselo ya le henhla lama tiyiselaka, na lapi ra fiberglass leri tiyiselaka ku hisa — hi kombela u tihlanganisa hina:
