Chemical Corrosion Resistance ya PTFE High-Temperature Fabric – Leswi Yi Tiyiselaka Na Leswi Yi Nga Tiyiseleki

Eka tifemeni ta tikhemikhali, tilayini ta electroplating ni ti- semiconductor fab, swifunengeto swa switirhisiwa ni mabandhi yo fambisa swi langutana ni nhlaselo lowu tshamaka wu ri kona hi tikhemikhali leti nga ni tihanyi. PTFE lapi ra mahiselo yale henhla (lapi ra fiberglass leri pfanganisiweke hi polytetrafluoroethylene) ritala ku boxiwile kahle hikokwalaho ka ku pfumala matimba ka rona ka ti khemikhali loku hlawulekeke. Kambe 'almost universal' resistance a hi 'universal' – swilo swi nga ri swingani leswi nga ni tihanyi swi nga yi hlasela, naswona mahiselo ya tlanga xiave xa nkoka.

Aokai PTFE yi ringetile lapi ra PTFE ku lwisana na madzana ya tikhemikhali. Nkongomiso lowu wu hlamusela leswi yi lwisanaka na swona, leswi faneleke ku papalatiwa, na ndlela leyi mahiselo ya khumbaka matirhelo ha yona.

Phurofayili ya Matirhelo Hinkwawo – Ku nga tirhi ka Tikhemikhali loku nga ekusuhi na Misava Hinkwayo

Lapi ra mahiselo yale henhla ra PTFE ri tinyungubyisa hi ku lwisana na ku bola ka tikhemikhali loku hlamarisaka hi ndlela yo hlawuleka, ku vekiwa exikarhi ka xiyimo xa le henhla xa switirhisiwa swa vunjhiniyara leswi tolovelekeke. Nhundzu leyi ya nkoka yisungula kusuka eka polytetrafluoroethylene coating yale handle, leyi vumbiwaka hi ti carbon-fluorine (CF) bonds to tiya leti lwisanaka na nhlaselo wa ti khemikhali.

Substrate ya fiberglass yale hansi ayi tirhi hi ti khemikhali – kambe loko ntsena PTFE coating yitshama yirikarhi yi onhaka, lapi ri tirha tani hi nchumu lowu nga kusuhi naku nga tirhi. Eka mahiselo ya nkarhi na nkarhi lawa ya tirhaka, lapi ra PTFE ritshama ritshamisekile swinene eka vunyingi bya ti acids to tiya, ti alkalis to tiya, ti organic solvents, na ti oxidizing agents.

Wide Range of Resistant Media – Leswi Lapi ra PTFE ri nga swi khomaka

Eka mahiselo ya nkarhi na nkarhi lawa ya tirhaka, swilo leswi switshama switshamisekile swinene eka vunyingi bya ti acids to tiya, ti alkalis to tiya, ti organic solvents, na ti oxidizing agents.

1. Ti- acid ta matimba

Sulphuric acid leyi hlanganisiweke, nitric acid, hydrochloric acid, phosphoric acid, na aqua regia (nkatsakanyo wa nitric na hydrochloric acids leyi n’okisaka nsuku) – PTFE yi tiyisela hinkwaswo. Ku hava ku onhaka loku pimiwaka loku humelelaka.

2. Ti alkali leti tiyeke

Sodium hydroxide (NaOH) na potassium hydroxide (KOH) solutions ayi na switandzhaku swo biha eka mahiselo ya kamara. Ku lwisana swi anama kuya eka tindzhawu totala ta alkaline.

3. Swintshuxo swa organic

PTFE ayi khuluki eka ti solvents hinkwato leti tivekaka. A yi nge pfimbi kumbe ku n’oka loko yi hlangana ni ti- ketone, ti- alcohol, ti- ether, ti- hydrocarbon, ti- solvent leti nga ni chlorinated kumbe ntlawa wun’wana ni wun’wana wa swintshuxo.

4. Swilo leswi endlaka leswaku ku va ni okisijini

Yikombisa ku tiyisela kahle swinene eka ti oxidizers ta matimba tofana na hydrogen peroxide (H2O2) na ti permanganates.

5. Swihlawulekisi leswi engetelekeke

• Hydrolysis-resistant – ayi khumbeki hi mati kumbe steam

• Ku tiyisela maxelo – UV na ku hlangana ehandle swivanga ku onhaka kutsongo

• Yi hlongola mafurha naswona yinga namarheli – matimba yale hansi yale henhla ya sivela ku namarhela

• Ku amukeriwa ka mati – kahle kahle zero (<0.01%) .

Swihlawulekisi – Tikhemikhali leti faneleke ku va na vuxiyaxiya eka tona

PTFE a yi lwisani na swona hinkwako. Yi endla nhluvuko na nhlayo yitsongo ya tikhemikhali leti tirhaka swinene ehansi ka swiyimo swo tika, leswi lavaka nyingiso wo hlawuleka hi nkarhi wa ku hlawuriwa ka swilo.

Aokai PTFE yi kandziyisa leswaku swihlawulekisi leswi a swi talanga kambe swa nkoka ku swi tiva:

H3: Tinsimbi ta alkali leti n’okiweke

Sodium (Na), potassium (K) na lithium (Li) leyi n’okiweke yi tshoveka swihlanganisi swa carbon-fluorine endzeni ka PTFE, leswi vangaka ku onhaka loku heleleke. Lowu i nsinya wa nawu endzhaku ka sodium-naphthalene etching eka vutshunguri bya le henhla bya PTFE.

H3: Ti compounds ta halogen leti tirhaka swinene ehansi ka mahiselo yale henhla na ntshikelelo wale henhla

• Kloroni ya trifluoride (ClF3) .

• Difluoride ya okisijini (OF2) .

• Gasi ya fluorine (F2) eka mahiselo yale henhla na ntshikelelo

Leswi swinga angula na kumbe hambi kuri ku hisa PTFE ehansi ka swiyimo swo tika swinene.

H3: Ku n’okisiwa ka ti alkali to tiya eka mahiselo yale henhla

Sodium hydroxide leyi n’okiweke (NaOH) kumbe potassium hydroxide (KOH) ehenhla ka kwalomu ka 300°C yi bola hi ku nonoka PTFE. Eka mahiselo ya kamara, a ku na vuyelo.

H3: Xitsundzuxo xa nkoka – ku onhaka ka ku peta swi paluxa fiberglass

Swipimelo leswinga laha henhla switirha ntsena eka xifunengeto xa PTFE xale henhla. Loko xifunengeto xi khwaxa, xi onhakile kumbe xi ri na ti pinholes, substrate ya fiberglass leyi nga ehansi yi ta va yi ri erivaleni. Fiberglass ayi na ku tiya ka kahle eka:

• Hydrofluoric acid (HF) – yi hatlisa ku n’okisa ti fibre ta nghilazi

• Ti alkali to hisa leti hlanganisiweke – ti hlasela nghilazi

Leswi hi swona swi endlaka leswaku ku hlayisa vutshembeki bya coating swiva swa nkoka swinene eka vukorhokeri bya ti khemikhali. Eka switirhisiwa leswi katsaka HF, languta filimi ya PTFE yo basa ematshan’wini ya sweswo.

Nkucetelo wa Mahiselo eka Ku Lwisana ka Tikhemikhali

Mahiselo ya tirha tani hi nchumu wa nkoka lowu lawulaka ku lwisana na ti khemikhali. Endzeni ka mahiselo ya yona ya nkarhi woleha ya vukorhokeri (hi ntolovelo -70°C kuya eka 260°C), kutshamiseka ka tikhemikhali ta PTFE kahlekahle aswi khumbekanga.

Hambiswiritano, mahiselo lawa yanga heriki lawa ya tlulaka 260°C yata:

• Hakatsongo-tsongo hunguta ku nga tirhi ka tikhemikhali ta PTFE

• Endla leswaku swilo leswi swi va ekhombyeni ro khukhuriwa hi swilo leswi hundzeletiweke leswi boxiweke laha henhla

• Hatlisisa ku onhaka ka mahiselo, ku endla tindhawu leti tsaneke laha nhlaselo wa tikhemikhali wu nga sungulaka kona

Data ya xikambelo xa Aokai PTFE: Eka 250°C leyi yaka emahlweni yi hlangana, lapi ra PTFE ri hlayisa >90% wa swivumbeko swa rona swo lwisana na tikhemikhali endzhaku ka masiku ya 200. Eka 280°C, matirhelo ya hunguteka swinene endzhaku ka mavhiki.

Eka switirhisiwa leswingana mahiselo yale henhla (>260°C) xikan’we naku hlangana na ti khemikhali, languta data ya xithekiniki kutani u endla swikambelo swokarhi swa matirhiselo.

Nkatsakanyo – Rini ku Hlawula Lapi ra PTFE eka Tindhawu ta Tikhemikhali

Aokai PTFE yi nyika malapi lawa ya funengetiweke hi PTFE eka tindzhawu leti lavaka tikhemikhali. Eka switirhisiwa leswi lavaka ku lwisana na HF kumbe ku tiyiseka lokukulu ka tikhemikhali, hi ringanyeta ku kamberiwa ehansi ka swiyimo swa xiviri swa ntirho kumbe ku tirhisa tigiredi ta filimi ya PTFE yo basa. Tihlanganise na hina hi tikhemikhali ta wena to karhi, mahiselo, na nkarhi wo hlangana na hina ku kuma xitsundzuxo.

Nhundzu leyi ya xithekiniki yi nyikiwa hi Jiangsu Aokai Thekinoloji ya Switirhisiwa Leswintshwa Co., Ltd.

Loko u lava swihlawulekisi leswi nga na vuxokoxoko, swiyimo swa xikombelo na swintshuxo leswi endleriweke photifoliyo ya hina ya swikumiwa leswi heleleke, ku katsa na malapi ya mahiselo ya le henhla ya PTFE, tithepi to namarhela ta mahiselo ya le henhla ya PTFE, mabandhi yo fambisa ya mesh ya PTFE, mabandhi ya muchini wo fusa lama nga riki na swirhabyani, lapi leri funengetiweke hi tlhelo rin’we ra PTFE, mabandhi yo fambisa lama nga hisiki na malapi ya fiberglass ya mahiselo ya le henhla, hi kombela u hi tihlanganisa hi tindlela leti landzelaka:

• Nkulukumba Guo: +86 18944819998

• Nkulukumba Liu: +86 13705266308

Hi seketela mimpimanyeto ya vukorhokeri ya vutshila na vutshembeki, naswona hi tinyiketerile hi ku hetiseka ku tisa swintshuxo swa hinkwaswo eka xin’we na nseketelo wa vukheta eka tikhayente hinkwato!
