Isimiso Sokusebenza
Izinzwa ze-oxygen ezincibilikisiwe ze-polaragraphic zisebenza ngokusekelwe ezimisweni ze-electrochemical, ikakhulukazi zisebenzisa i-Clark electrode. Inzwa iqukethe i-cathode yegolide, i-anode yesiliva, kanye ne-electrolyte ethile, konke okuvalwe yi-membrane ekhethiwe evulekayo.
Ngesikhathi sokulinganisa, i-oxygen iyasabalala nge-membrane iye ku-sensor. Ku-cathode (i-electrode yegolide), i-oxygen iyancishiswa, kanti ku-anode (i-electrode yesiliva), kwenzeka i-oxidation. Le nqubo ikhiqiza ugesi wokusabalalisa olingana nokuhlushwa kwe-oxygen encibilikisiwe kusampula, okwenza kube nokulinganisa okunembile.
Izici Eziyinhloko
Izinzwa ze-oxygen ezincibilikisiwe ze-polaragraphic zamukelwa kabanzi ngenxa yezici zazo ezihlukile:
- Ukunemba Okuphezulu Nokuzwela:

Lokhu kubalulekile ezinhlelweni zokusebenza ezifana nokuqapha amanzi okuphakelwa kwebhoyila kanye nokuqapha amanzi ahlanzekile kakhulu e-semiconductor.
- Isikhathi Sokuphendula Esisheshayo:
- Ngokuvamile iphendula ngaphansi kwemizuzwana engama-60 (eminye imikhiqizo ifinyelela izikhathi zokuphendula zingakapheli imizuzwana eyi-15), ikhombisa ngokushesha izinguquko emazingeni e-oxygen ancibilikile.
- Izidingo Zokulungisa Eziphansi:
- Imiklamo yesimanje ayidingi ukushintshwa njalo kwe-electrolyte, okunciphisa izindleko zokugcinwa kwesikhathi eside kanye nemizamo. Kodwa-ke, ukulinganiswa ngezikhathi ezithile kanye nokufakwa kabusha kwe-membrane kusadingeka.
- Ukuqina Okuqinile kanye nekhono Lokulwa Nokuphazamiseka:
- I-membrane ekhethiwe evulekayo ihlukanisa ngempumelelo ukungcola kanye nezinto ezingcolisayo, iqinisekisa ukulinganiswa okuzinzile nokuthembekile.
- Isinxephezelo Sokushisa Okuzenzakalelayo:
- Iningi lezinzwa lifaka inzwa yokushisa eyakhelwe ngaphakathi ukuze kulungiswe amaphutha okulinganisa abangelwa ukushintshashintsha kwezinga lokushisa.
- Umklamo Ohlakaniphile Nohlanganisiwe:
- Izinzwa eziningi zihlonyiswe ngezixhumi zokuxhumana (isb., i-RS485) futhi zisekela amaphrothokholi ajwayelekile (isb., i-Modbus), okuvumela ukuhlanganiswa ezinhlelweni zokulawula ezenzakalelayo kanye namapulatifomu e-IoT okuqapha idatha ekude.
Izimo Zohlelo Lokusebenza
Izinzwa ze-oxygen ezincibilikisiwe ze-polaragraphic zisetshenziswa kabanzi emikhakheni eyahlukene:
- Izinqubo Zezimboni Nokwelashwa Kwamanzi:
- Ukuqapha Amanzi Okuphakelwa Kwebhoyila: Kubalulekile ezimbonini ezifana nokukhiqizwa kukagesi, amakhemikhali, kanye ne-metallurgy, lapho i-oxygen encibilikisiwe ngokweqile ingabangela ukugqwala okukhulu kwamapayipi ensimbi kanye nemishini.
- Ukwelashwa Nokugadwa Kokukhishwa Kwamanzi Angcolile: Amazinga e-oxygen ancibilikisiwe athinta ngqo umsebenzi wamagciwane ezinqubweni zokwelashwa kwamanzi angcolile kamasipala kanye nezimboni.
- Ukukhiqizwa Kwamanzi Okune-Semiconductor kanye Nokuhlanzeka Okukhulu: Izidingo zamanzi ahlanzekile kakhulu ekukhiqizweni kwe-elekthronikhi zidinga ukuqapha okunembile kwe-oxygen encibilikisiwe.
- Ukuqapha Imvelo kanye Nocwaningo Lwesayensi:
- Ukuqapha Ikhwalithi Yamanzi Angaphezulu, Umfula, kanye Nechibi: I-oxygen encibilikisiwe iyisibonakaliso esibalulekile samandla okuzihlanza kwamanzi kanye nempilo yemvelo.
- Ukufuya Izilwane Zasemanzini: Ukuqapha umoya-mpilo oncibilikisiwe ngesikhathi sangempela kusiza ekuvimbeleni ukuntuleka komoya-mpilo ezintweni eziphilayo zasemanzini, okuthuthukisa ukusebenza kahle kwezolimo.
- Izimboni ze-Biotechnology kanye nezeMithi:
- Ukuhlushwa kwe-oxygen encibilikisiwe kumele kulawulwe ngokunembile kuma-bioreactors (isb., ukuvutshelwa kanye nokukhula kwamaseli) ukuqinisekisa izimo zokukhula ezifanele zama-microorganisms noma amaseli.
- Imboni Yokudla Neziphuzo:
- Amazinga e-oxygen ancibilikisiwe angathinta ukunambitheka komkhiqizo, umbala, kanye nesikhathi sokuphelelwa yisikhathi, okwenza ukuqapha kubalulekile ngesikhathi sokukhiqiza.
Amazwe/Izifunda Ezisetshenziswa Ngokuvamile
Ukwamukelwa kwezinzwa ze-oxygen ezincibilikisiwe ze-polaragraphic kuhlobene kakhulu namazinga okukhula kwezimboni, imithethonqubo yezemvelo, kanye nentuthuko yezobuchwepheshe:
- I-America esenyakatho:
- I-United States neCanada ziphoqelela imithetho eqinile yokuvikela imvelo kanye nezindinganiso zekhwalithi yamanzi, okwenza lezi zinzwa zisetshenziswe kabanzi ezimbonini ezisezingeni eliphezulu njengamandla kagesi, amakhemikhali, kanye nemithi.
