Xana Lapi Ra PTFE Ra Mahiselo Ya Le Henhla Ri Tiyisela Ku Yini Hi Tikhemikhali?

Eka switirhisiwa swa tikhemikhali, tilayini ta electroplating ni ti- semiconductor fab, switirhisiwa swi tshama swi ri eku hlanganeni ni ti- acid leti nga ni tihanyi, ti- alkali ni swintshuxo. Ku hlawula switirhisiwa leswi faneleke swo sirhelela swi khumba vuhlayiseki na vutomi bya switirhisiwa hi ku kongoma.

PTFE (polytetrafluoroethylene) yitala ku vuriwa 'plastic king' hikokwalaho ka ku pfumala matimba ka yona ka ti khemikhali lokukulu. Kambe 'inert' a swi vuli 'invincible' – hi tihi tikhemikhali leti nga yi onhaka hakunene? Xana mahiselo ni ku dzikisa mianakanyo swi khumba njhani matirhelo ya yona?

Eka Aokai PTFE , hi hete malembe hi ri karhi hi ringeta Malapi lawa ya funengetiweke hi PTFE ku lwisana na tindzhawu ta xiviri ta tikhemikhali. Xihloko lexi xi avelana leswi hi swi kumeke leswaku xi ku pfuna ku hlawula hi vutlhari.

Tikhemikhali Leti Lapi Ra Mahiselo Ya Le Henhla Ya PTFE Ri Lwisanaka

1. Tiasidi ta Matimba

Lapi ra PTFE ri tisa ku tiya lokunene eka:

• Asidi ya sulphuric (H2SO4) .

• Asidi ya nitric (HNO3) .

• Asidi ya hayidirokhiloriki (HCl) .

• Asidi ya fosforiki (H3PO4) .

• Ti acid leti endlaka oxidizing swinene tofana na aqua regia na hydrofluoric acid (HF) .

2. Ti-Alkali leti tiyeke

Yi lwisana na sodium hydroxide (NaOH), potassium hydroxide (KOH), mati ya ammonia (NH3·H2O), na swin’wana swo tiya swa alkaline.

3. Switolwa swa Organic

A yi tirhi hi tikhemikhali eka swintshuxo swo tala swa organic, ku katsa na ti alcohol (methanol, ethanol), ti ketones (acetone, MEK), ti hydrocarbons to nun’hwela (benzene, toluene, xylene) na petirolo.

4. Tikhemikhali Tin’wana

Yi hlayisa matirhelo yo tiya eka ti oxidants (xikombiso, hydrogen peroxide), munyu (sodium chloride, sodium sulfate), na tigasi leti onhaka (chlorine, hydrogen sulfide).

Swipimelo – Tikhemikhali Leti Onhaka Lapi ra PTFE

Hambi leswi kungana ku tiya ka tikhemikhali ta xiyimo xale henhla, lapi ra PTFE ra mahiselo yale henhla rina swipimelo ehansi ka swiyimo swa mahiselo yale henhla swinene kumbe ya xiyimo xale henhla. Tikhemikhali ti nga ri tingani to karhi ti nga ha onha tanihilaha swi xaxametiweke hakona laha hansi:

Ku engetela kwalaho, lapi leri pfanganisiweke na PTFE a ri bumabumeriwi ku tirhisiwa na:

• Chlorine trifluoride (ClF3) – ku pfurha loku tiendlekelaka kunga humelela

• Oxygen difluoride (OF2) – ku cinca ka madzolonga

• Fluorine ya mati kumbe ya gasi (F2) eka mahiselo yale henhla – yi hlasela PTFE

Swilo leswi khumbaka ku tiya ka tikhemikhali ka PTFE Coated Fabric

Swilo swotala swi khumba ku tiya ka xiviri ka ku bola ka lapi ra mahiselo yale henhla ya PTFE eka switirhisiwa swa misava ya xiviri:

• Mahiselo: Ku tirha ka ti khemikhali loku tiyeke ku hlayisiwa endzeni ka -70°C kuya eka 260°C. Ku lwisana na switsotswana swihunguteka eka ti khemikhali tokarhi eka mahiselo yale henhla swinene.

• Ku hlanganisiwa: Ku nyuperisiwa nkarhi woleha eka switirhisiwa leswinga onhaka swinene swinga onha matirhelo ya swilo. Ku kamberiwa endhawini ya kona swa hlohleteriwa.

• Ntshikelelo wa michini: Ku hlanganisiwa ka ku bola ka tikhemikhali na ku hlangana ka michini swi hatlisisa ku dyuhala. Ku sirhelela PTFE coating eka ku khwaxa i swa nkoka – loko se yi onhakile, fiberglass leyi nga ehansi ka yona yi va ekhombyeni.

• Nkarhi wo hlangana: Ku lwisana na ku khuluka ka nkarhi wo koma swihambana na ku nyuperisiwa loku yaka emahlweni.

• Ntshikelelo: Ntshikelelo lowu tlakukeke wu nga sindzisa tikhemikhali ku nghena eka ti- microscopic pores kumbe swihoxo swa coating.

Data ya lab ya Aokai PTFE yi kombisa leswaku ku tirhisana ka temperature-concentration switala ku tekeriwa ehansi. Xikombiso, lapi ra PTFE leri tshamaka malembe eka 50% sulfuric acid eka 100°C ringa kombisa ku basa ka le henhla endzhaku ka tinhweti eka 200°C hi nhlayo leyi fanaka. Minkarhi hinkwayo tirhisa margin ya vuhlayiseki.

Nkatsakanyo – Ku Tiyisela ka Tikhemikhali ka Lapi ra Mahiselo ya le Henhla ya PTFE

Eka tindzhawu totala ta ti khemikhali ta ti indasitiri, lapi leri pfanganisiweke na PTFE rinyika matirhelo yo tshembheka, lawa ya tshamaka nkarhi woleha. Hambiswiritano, minkarhi hinkwayo tiyisisa ku fambisana ehansi ka swiyimo swa xiviri swa ntirho – ngopfu ngopfu mahiselo, ku hlangana, na ntshikelelo wa michini.

Hiku komisa , PTFE lapi ra mahiselo yale henhla rinyika ku tiya lokukulu eka kwalomu ka ti acid hinkwato, alkalis, na ti organic solvents endzeni ka ndzhawu ya rona ya ntolovelo yo tirha (-70°C kuya eka 260°C). Swihlawulekisi swa nkoka i tinsimbi ta alkali leti n’okiweke na switirhisiwa swo tiya swa fluorinating. Ti oxidizing acids to hisa, leti hlanganisiweke na tona ti lava vuxiyaxiya lebyi engetelekeke.

Hi ku tirhisa, mahiselo, ku dzikisa mianakanyo ni ntshikilelo wa michini swi tirhisana leswaku swi khumba vutomi bya swilo leswi vonakaka. Eka swiyimo swa nkoka, hi ringanyeta ku kamberiwa endhawini kumbe ku chela margin ya vuhlayiseki ya 30-40°C ehansi ka mahiselo yale henhla lawa ya ringanyetiweke.

Xana u lava mpfuno eka ndhawu yo karhi ya tikhemikhali? Xipano xa xithekiniki xa Aokai PTFE ’s xi hlengeletile datha ya ku bola ka madzana ya swihangalasamahungu. Tihlanganisi na hina ku kuma nkongomiso wo hlawula kumbe swintshuxo swa malapi lama pfanganisiweke na PTFE lama endleriweke wena.

Yi humesiwile hi Jiangsu Aokai Switirhisiwa Leswintshwa Thekinoloji Co., Ltd.

Ku kuma vuxokoxoko bya tipharamitha, swiyimo swa xikombelo, na swintshuxo leswi endleriweke ku tirhisiwa ka switirhisiwa swa nxaxamelo lowu heleleke ku katsa na lapi ra mahiselo ya le henhla ya PTFE, thepi ya mahiselo ya le henhla ya PTFE, bandi ra mesh ra PTFE, bandi ro hlanganisa leri nga na swirhabyani, lapi ra PTFE ra tlhelo rin’we, bandi ro fambisa leri lwisanaka na mahiselo ya le henhla na lapi ra fiberglass , hi kombela u ntshunxeka ku hi tihlanganisa:
