Izinguquko Ekumelaneni Nokugqwala kwe-PTFE Yendwangu Yezinga Lokushisa Ephakeme Kumidiya Ehlukene Yamakhemikhali (Ama-Oxidants Aqinile, Izincibilikisi Ze-Organic, njll.)

Ilethwa kuwe i-Jiangsu Aokai New Materials, umkhiqizi ochwepheshe we-PTFE izinga lokushisa eliphakeme lendwangu ye-PTFE.PTFE idume ngokuzinza kwamakhemikhali okuvelele, ephuma kusakhiwo samangqamuzana esiqinile sezinto zayo eziyinhloko — i-Polytetrafluoroethylene (PTFE). Uma ivezwe emithonjeni yamakhemikhali ehlukene, ukumelana nokugqwala kwayo kuhlala kungaguquki, kunezimo ezimbalwa kuphela ezihlukile ezidinga ukunakwa okukhethekile. Lesi sihloko sichaza kabanzi ngezinguquko zayo zokusebenza ezindaweni ezihlukahlukene zesevisi.

1. Ama-oxidants Aqinile: Indwangu ye-PTFE Yezinga Lokushisa Ephakeme Ihlala Ingangeni Ngamakhemikhali

Ezindaweni eziqinile ze-oxidizing, ukumelana nokugqwala kwendwangu ye-PTFE yokushisa okuphezulu akushintshi. Imelana nokuguguleka okuvela ezinhlobonhlobo zama-oxidants aqinile, okuhlanganisa i-potassium permanganate, i-hydrogen peroxide, i-sodium hypochlorite ne-potassium dichromate.Izuza ekwakhekeni kwayo kwamangqamuzana ezinzile kakhulu, indwangu ayikhiqizi ukusabela kwamakhemikhali, ukuvuvukala noma ukuwohloka lapho ithintana nama-oxidants angenhla. Ngakho-ke, lapho isetshenziswa ezinqubweni zamakhemikhali e-oxidation aqinile, amandla ayo angokomzimba kanye nezakhiwo ezingaphezulu zigcinwa kahle, ziletha ukwethembeka okuhle kakhulu kwesevisi yesikhathi eside.

2. I-Organic Solvents: Ukusebenza Okuphelele Kokumelana

Lapho icwiliswa kuzinyibilikisi eziphilayo, indwangu ye-PTFE yokushisa ephezulu igcina ukumelana nokugqwala okuzinzile. Ifaka ukungabi namakhemikhali okwedlulele ngokumelene notshwala (i-ethanol), ama-ketone (i-acetone), ama-hydrocarbon anephunga elimnandi (i-toluene, i-xylene), ama-halogenated hydrocarbon, uphethiloli, amafutha kanye nezinhlobonhlobo ze-resin coatings.

Idatha yokuhlola ibonisa ukuthi ngisho naku-300℃, ambalwa kuphela ama-alkane ane-perfluorinated abangela ukuhlakazeka kancane. Emazingeni okushisa asekamelweni, indwangu yokushisa ephezulu ye-PTFE ngeke incibilike noma ivuvuke kunoma iyiphi i-solvent ephilayo eyaziwayo.Uma isetshenziswa njengama-gaskets noma ama-conveyor belt substrates, imelana nokungena kanye nokulimala yimidiya ye-organic, inweba kakhulu impilo yesevisi yendawo yayo yokusebenza.

3. Ama-Acid, Ama-Alkali kanye Nosawoti: Ukuguquguquka Okugcwele Kwesimo

Ngokungeziwe kumidiya engenhla, indwangu yezinga lokushisa eliphezulu ye-PTFE ibonisa izinguquko zokusebenza ezinganakwa ku-asidi eqinile, i-alkali eqinile nezimo zikasawoti ophezulu.

Imelana nokucwiliswa isikhathi eside ku-concentrated sulfuric acid, nitric acid, hydrochloric acid, hydrofluoric acid ngisho ne-aqua regia. Akukho ukwehla kwesisindo okusobala noma ukwehla kokusebenza kwemishini okwenzekayo, ngisho nasekubiliseni ama-asidi aqinile. Iphinde imelane nokuhlakazeka kanye nokuwohloka kwamandla lapho kuvezwa izinga lokushisa eliphakeme lama-alkali aqinile njenge-sodium hydroxide ne-ammonia. Emanzini.Emoyeni egqwalayo okuhlanganisa amanzi olwandle, amanzi ane-brine, igesi ye-chlorine ne-sulphur dioxide, ihlale igcina izakhiwo zayo zasekuqaleni ezingeyona induku, ukumelana nesimo sezulu kanye nokufakwa kukagesi.

4. Okuhlukile Okukhethekile: Izimo Zokusebenza Ezidlulele Okufanele Zigwenywe

Nakuba indwangu yokushisa ephezulu ye-PTFE inobubanzi obubanzi bokumelana nokugqwala, inombolo encane yamakhemikhali akhethekile izokhubaza ukusebenza kwayo kokuvikela.

Okokuqala, ukuthintana nezinsimbi ze-alkali ezincibilikisiwe (njenge-sodium ne-potassium) kufanele kugwenywe, njengoba lezi zinto zizobhubhisa ukwakheka kwamaketanga wamangqamuzana.

Izinga lokushisa liphinde libe ngumkhawulo obalulekile: uma izinga lokushisa le-ambient lidlula u-400℃, i-PTFE iqala ukubola okushisayo futhi ikhiphe igesi enobuthi, okuholela ekulahlekeni kokubili ukumelana nokugqwala namandla emishini.

Isifinyezo

Kwabezindaba eziningi zamakhemikhali ezimboni, i-PTFE izinga lokushisa eliphezulu indwangu igcina ukuncipha kokusebenza okuncane. Ukubekezelela kwayo okuphakeme kuyenza ibe yimpahla efanelekile yokulwa nokugqwala, ukuvala uphawu nokukhulula Inqobo nje uma ukuthintana nezinsimbi ze-alkali ezincibilikisiwe kanye namazinga okushisa aphezulu kakhulu okubola kugwenywa, ukumelana kwayo nokugqwala okuhle kakhulu kungasetshenziswa ngokugcwele, kuvikele indawo yayo engenakubuyiseleka ezimeni ezinzima zokusebenza kwamakhemikhali.

Lokhu okuqukethwe kunikezwe i- Jiangsu Aokai New Material Technology Co., Ltd.

Sinikeza uhla oluphelele lwemikhiqizo: Indwangu yokushisa ephezulu ye-PTFE, itheyipu yokushisa ephezulu ye-PTFE, ibhande le-PTFE elinezikhala lokushisa eliphezulu, ibhande lomshini wokuhlanganisa elingenamthungo, indwangu eboshwe ohlangothini olulodwa lwe-PTFE, ibhande lokuhambisa elimelana nokushisa okuphezulu kanye nendwangu ye-fiberglass ekwazi ukumelana nokushisa okuphezulu.Ukuze uthole imingcele enemininingwane, izimo zohlelo lokusebenza nezixazululo ezenziwe ngokwezifiso, sicela usithinte:
