Ha Yini Lapi Ra Mahiselo Ya Le Henhla Ra PTFE Ri Nga Tiyiseleli Langavi Eka Ndzilo Lowu Pfulekeke? Hi Yihi Ndlela Ya Yona Yo Sivela Langavi Hi Microscopic?

Jiangsu Aokai New Materials, muendli lonkulu wa malapi ya PTFE ya mahiselo yale henhla, wa hlamusela:

PTFE lapi ra mahiselo yale henhla rikota swinene eka malangavi eka ndzilo lowu pfulekeke, ngopfu ngopfu hikokwalaho ka xivumbeko xa molecular na thermal decomposition mechanism ya core material ya yona — polytetrafluoroethylene (PTFE). Ku sivela malangavi ya yona aswi titsheganga hi swisivela malangavi leswi engeteriweke kufana na switirhisiwa leswi tolovelekeke, kambe swisungula kusuka eka inertness ya yona ya ti khemikhali ya ntumbuluko xikan’we na mahanyelo yo hlawuleka ya ku bola.

Leswi swi nga twisisiwa ku suka eka swiyimo swinharhu:

1. Molecular yo tiya 'Armour': Eneji ya Bond ya le Henhla na Leyara yo Sirhelela

·  Swihlanganisi swo tiya swa khaboni-fluorine (C–F) : Timolekhuli ta PTFE ti vumbiwa hi nkolo wa khaboni chain lowu rhendzeriweke swinene hi tiatomo ta fluorine. C–F bond i yin’wana ya ti khemikhali leti tiyeke swinene leti tivekaka, laha kungana matimba ya bond ya kwalomu ka 485 kJ/mol. Eneji yale henhla swinene (mahiselo) ya laveka kuva yi tshoveka, ku endla layini yosungula ya nsirhelelo.

·  Vuyelo byo sirhelela bya tiatomo ta fluorine : Tiatomo letikulu ta fluorine leti nga na charge yo biha ti pakiwile hi ku enta, ti tirha tanihi xisirhelelo xo tiya lexi pfalaka hi ku helela nxaxamelo wa khaboni ya le ndzeni. Xisirhelelo lexi xi sivela ti khemikhali totala (kukatsa na oxygen) kuva tinga ngheni eka carbon chain naswona xi sivela swinene ti oxidation reactions leti lavekaka eka ku hisiwa.

2. Ku bola loku nga hisiki: Depolymerization Ematshan’wini yo Hisa

·  Chain scission before oxidation : Ehansi ka mahiselo yale henhla, swihlanganisi leswinga tsana swinene swa carbon-carbon (C–C) endzeni ka PTFE swi tshoveka loko C–F yinga se hlangana. Tikhetane ta timolekhuli ti sungula ku bola okisijini yi nga si hlanganyela eka ku angula.

·  Xiendliwa lexikulu i monomer : Loko yi tshoveka, PTFE ngopfu ngopfu yi hundza eka depolymerization , yi humesa ti tetrafluoroethylene (C2F4) monomers kusuka eka makumu ya ti chain. Nchumu lowu wu hundzuka musi ematshan’weni yo hisiwa hi matimba lama humesaka ku hisa lokukulu ni tigasi leti pfurhaka.

·  Gas-phase barrier effect : C2F4 Gasi kusuka eka depolymerization yi tsindziyerile kutlula moya naswona yitshama ekusuhi na le henhla, yi endla leyara ya gasi ya nkarhinyana leyi hungutaka nhlayo ya oxygen naswona yi ya emahlweni yi tshikelela ku hisa.

3. Ntirho wo Seketela wa Glass Fibre Substrate

Lapi ra mahiselo yale henhla ya PTFE i xivumbeko lexi endliweke hiku peta PTFE eka lapi ra fibre ya nghilazi. Fibre ya nghilazi hi yoxe i nchumu lowu nga pfurhiki lowu nga riki na ntumbuluko. Tanihi marhambu ya xivumbeko, switiyisisa leswaku hambi loko leyara ya PTFE yale henhla yi dyiwa hiku hetiseka ehansi ka kuhisa lokukulu, nchumu lowu awu n’oki kumbe ku thona kufana na pulasitiki yo basa, leswi hlayisaka vutshembeki bya xivumbeko xikan’we naku sivela ku hangalaka ka malangavi.

Swifanele ku kandziyisiwa leswaku PTFE ayi pfurhile malangavi , ayi pfurhi hiku hetiseka.Loko yi hisiwa ehenhla ka ndzhawu ya yona yo n’oka (327°C) naswona yi ya emahlweni, ya bola no humesa musi lowu nga na chefu. Hi ntolovelo yi tiyisela mahiselo ya nkarhi woleha kuya fika eka 260°C naswona yitshama yirikarhi yitshamiseka swa xinkarhana eka 300–360°C.

Ku bola eka ndzilo lowu pfulekeke : Loko wu hlangana hi ku kongoma eka ndzilo lowu pfulekeke (ehenhla swinene ka mahiselo ya wona ya ku bola), leyara ya PTFE ya bola, kambe endlelo leri ari humesi kuhisa loku ringaneleke kumbe swilo leswi pfurhaka kuva swikota ku kondletela ku hisa. Loko swi hlanganisiwa ni nseketelo wa fibre ya nghilazi, malangavi a ma nge hangalaki ma ya emahlweni.

Hi ku komisa, lapi ra mahiselo ya le henhla ya PTFE a ri pfurhi hikuva nchumu wa rona wa nkoka PTFE wu endleriwe hi timolekhuli ku lwisana na ku hisiwa .Swiboho swa tikhemikhali swa eneji ya le henhla, tindlela to hlawuleka to bola, na marhambu ya fibre ya nghilazi leyi nga pfurhiki loko swi hlanganisiwa swi vumba xisirhelelo xo tiya lexi nga pfurhiki ndzilo.

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 ku tirhisiwa ka nxaxamelo wa hina hinkwawo wa swikumiwa — 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 ya PTFE, bandi leri nga riki na swirhabyani ra michini yo boha, lapi ra PTFE ra tlhelo rin’we, bandhi ra conveyor leri tiyiselaka mahiselo ya le henhla, lapi ra fibre ra nghilazi leri tiyiselaka mahiselo ya le henhla na swin’wana leswi fambelanaka na swona products — hi kombela u hi tihlanganisa:
