Inganyangeki Njani Kwimichiza Ilaphu le-PTFE Lobushushu obuphezulu?

Kwizityalo zemichiza, imigca ye-electroplating, kunye ne-semiconductor fabs, izixhobo zihlala zibonakaliswe kwii-acids ezinobundlobongela, i-alkali, kunye ne-solvents. Ukukhetha imathiriyeli efanelekileyo yokukhusela ichaphazela ngokuthe ngqo ukhuseleko kunye nobomi besixhobo.

I-PTFE (i-polytetrafluoroethylene) idla ngokubizwa ngokuba 'yinkosi yeplastiki' ngenxa yokungangeni kweekhemikhali okugqithisileyo. Kodwa 'inert' ayithethi 'ayinakoyiswa' – zeziphi iikhemikhali ezinokuyonakalisa ngokwenene? Ubushushu kunye nokugxila kuchaphazela njani ukusebenza kwayo?

Kwi-Aokai PTFE , sichithe iminyaka sivavanya Amalaphu agqunywe nge-PTFE ngokuchasene nemekobume yeekhemikhali zehlabathi yokwenyani. Eli nqaku labelana ngeziphumo zethu zokukunceda ukhethe ngobulumko.

Iikhemikhali Ukuba PTFE High-Ubushushu Ilaphu lixhathisa

1. Ii-Acids ezomeleleyo

Ilaphu le-PTFE linikezela ukuchasana okugqwesileyo:

• Iasidi yesulfuric (H₂SO₄)

• Iasidi yenitric (HNO₃)

• I-Hydrochloric acid (HCl)

• I-Phosphoric acid (H₃PO₄)

• Iiasidi ezine-oxidizing kakhulu njenge-aqua regia kunye ne-hydrofluoric acid (HF)

2. IiAlkalis Ezomeleleyo

Ukumelana nesodium hydroxide (NaOH), potassium hydroxide (KOH), amanzi ammonia (NH₃·H₂O), kunye nezinye izinto ezinamandla zealkaline.

3. Izinyibilikisi zeOrganic

Anert ngokwekhemikhali ngokuchasene nezinyibilikisi ezininzi eziphilayo, kubandakanya ialkoholi (methanol, ethanol), iiketones (iacetone, MEK), iihydrocarbons ezinuka kamnandi (benzene, toluene, xylene), kunye nepetroli.

4. Eminye imichiza

Igcina ukusebenza okuzinzileyo ngokuchasene ne-oxidants (umzekelo, i-hydrogen peroxide), iityuwa (i-sodium chloride, i-sodium sulfate), kunye neegesi ezidliwayo (i-chlorine, i-hydrogen sulfide).

Unyino – Iikhemikhali Ezonakalisa Ilaphu le-PTFE

Ngaphandle kokuchasana kweekhemikhali eziphezulu, i-PTFE i-high-temperature fabrics inemida phantsi kobushushu obuphezulu okanye iimeko eziphakamileyo. Iikhemikhali ezimbalwa ezithile zinokubangela umonakalo njengoko kudweliswe ngezantsi:

Ukongeza, ilaphu eligqunywe yi-PTFE ayikhuthazwa ukuba lisetyenziswe:

• I-Chlorine trifluoride (ClF₃) - ukuvutha okuzenzekelayo kunokwenzeka

• I-oxygen difluoride (OF₂) - ukusabela ngobundlobongela

• Ulwelo okanye igesi yefluorine (F₂) kumaqondo obushushu aphezulu - ihlasela i-PTFE

Imiba echaphazela ukunyangwa kwemichiza ye-PTFE iFabric Coated

Izinto ezininzi zichaphazela ukona kwe-corrosion yokwenyani ye- PTFE yobushushu obuphezulu kwilaphu kwizicelo zehlabathi lokwenyani:

• Ubushushu: Ukusebenza kweekhemikhali okuzinzileyo kugcinwa ngaphakathi -70 ° C ukuya kuma-260 ° C. Ukuxhathisa kuyehla ngokuchasene neekhemikhali ezithile kumaqondo obushushu aphezulu ngokugqithisileyo.

• Ugxininiso: Ukuntywiliselwa ixesha elide kumajelo eendaba ezonakalisayo kungonakalisa ukusebenza kwemathiriyeli. Uvavanyo lwendawo luyacetyiswa.

• Uxinzelelo lomatshini: I-corrosion yeekhemikhali edibeneyo kunye nokuxubana koomatshini kukhawuleza ukuguga. Ukukhusela i- PTFE yokwambathisa kwimikrwelo kubalulekile - xa yonakele, i-fiberglass engaphantsi iba sesichengeni.

• Ubungakanani bexesha: Ukumelana nokuchaphaza kwexesha elifutshane kwahlukile kuntywiliselo oluqhubekayo.

• Uxinzelelo: Uxinzelelo oluphezulu lunokunyanzela iikhemikhali kwi-microscopic pores okanye iziphene zokugquma.

Idatha yelebhu ye-Aokai PTFE ibonisa ukuba iqondo lobushushu-loxinaniso luhlala lujongelwa phantsi. Umzekelo, ilaphu le-PTFE elihlala iminyaka kwi-50% ye-asidi yesulfuric kwi-100 ° C inokubonisa ubumhlophe bomphezulu kwiinyanga kwi-200 ° C kunye noxinaniso olufanayo. Hlala usebenzisa umda wokhuseleko.

IsiShwankathelo – Ukumelana neMichiza ye-PTFE yeFabric yoBubushushu obuphezulu

Kwiindawo ezininzi zeekhemikhali zemizi-mveliso, ilaphu eligqunywe yi-PTFE libonelela ngokuthembekileyo, ukusebenza okuhlala ixesha elide. Nangona kunjalo, soloko uqinisekisa ukuhambelana phantsi kweemeko zokusebenza zangempela - ngakumbi ubushushu, ugxininiso, kunye noxinzelelo lomatshini.

Isishwankathelo , Ilaphu le-PTFE lobushushu obuphezulu libonelela ngokuxhathisa okubalaseleyo phantse kuzo zonke iiasidi, iialkali, kunye nezinyibilikisi zendalo ngaphakathi koluhlu oluqhelekileyo lokusebenza (-70 ° C ukuya kuma-260 ° C). Izinto ezingaphandle ezingundoqo zizinyithi zealkali ezinyibilikisiweyo kunye nee-agent ezinamandla zokuthambisa. Iiasidi ezitshisayo, ezigxininisiweyo ze-oxidizing nazo zifuna ukulumka ngakumbi.

Ngokwesiqhelo, ubushushu, ugxininiso, kunye noxinzelelo lomatshini zisebenza kunye ukuchaphazela ubomi bezinto eziphathekayo. Kwiimeko ezinzima, sincoma ukuvavanywa kwisayithi okanye ukusebenzisa i-30-40 ° C yokhuseleko lomda ongaphantsi kweqondo lokushisa eliphezulu.
