I-Carbon Dioxide (CO2)

Imingcele yezobuchwepheshe

I-Carbon dioxide, uhlobo lwenhlanganisela ye-carbon oxygen, enefomula yamakhemikhali ethi CO2, iyigesi engenambala, engenaphunga noma engenambala engenaphunga elimnandi elinokunambitheka okumuncu esixazululweni salo esimanzi ngaphansi kwezinga lokushisa elivamile nokucindezela. Kubuye kube yigesi evamile yokushisa kanye nengxenye yomoya. Okukodwa (okubalwa ku-0.03% -0.04% wesamba sengqikithi yomkhathi). Mayelana nezakhiwo ezibonakalayo, i-carbon dioxide iyigesi engenambala futhi engenaphunga ekamelweni lokushisa nokucindezela. Inokuminyana okuphezulu kunomoya futhi iyancibilika kuzincibilikisi eziningi eziphilayo njengamanzi nama-hydrocarbon. Ngokuphathelene nezakhiwo zamakhemikhali, enye ye-carbon dioxide carbon oxygen compounds iyinto engaphili. Ayisebenzi ngamakhemikhali futhi inokusimama okuphezulu kokushisa (kuphela u-1.8% wokubola ngo-2000°C). Ayikwazi ukushisa, ngokuvamile ayikusekeli ukuvutha, futhi ine-asidi. Ama-oksidi anezakhiwo ezifanayo nama-acidic oxides. Ngenxa yokuthi zisabela emanzini ukuze zikhiqize i-carbonic acid, ziyi-anhydrides ye-carbonic acid. Mayelana nobuthi bayo, ucwaningo luye lwabonisa ukuthi i-carbon dioxide ene-concentration ephansi ayinobuthi, kuyilapho i-carbon dioxide ene-concentration ephezulu ingaba nobuthi ezilwaneni. I-carbon dioxide ene-high-purity isetshenziswa kakhulu embonini ye-electronics, ucwaningo lwezokwelapha kanye nokuxilongwa komtholampilo, i-carbon dioxide lasers, igesi yokulinganisa izinsimbi zokuhlola kanye nokulungiswa kwamanye amagesi ahlanganisiwe akhethekile, futhi isetshenziswa njengomlawuli ku-polyethylene polymerization. I-gaseous carbon dioxide isetshenziselwa iziphuzo ezibandayo ezine-carbonized, ukulawula i-pH ezinqubweni zokwelashwa kwamanzi, ukucubungula amakhemikhali, ukulondolozwa kokudla, ukuvikelwa okungenayo kumakhemikhali nokudla, igesi yokushisela, isikhuthazi sokukhula kwezitshalo, sisetshenziselwa ukuqinisa isikhunta nama-cores futhi sisetshenziselwa ukusakaza imishini ye-Pneumatic. ziphinde zisetshenziswe njenge-diluent yegesi yokuvala inzalo (okungukuthi, ingxube ye-ethylene oxide ne-carbon dioxide isetshenziswa njengesibulala-magciwane, isibulala-zinambuzane, kanye i-fumigant Isetshenziswa kakhulu ekubulaleni inzalo ezintweni zikagesi zezokwelapha, izinto zokupakisha, izingubo zokugqoka, uboya, okokulala, njll. I-carbon dioxide ewuketshezi isetshenziswa njengesiqandisi, ukuhlola izinga lokushisa eliphansi kwendiza, imicibisholo nezingxenye ze-elekthronikhi, ukuthuthukisa ukutholakala komthombo kawoyela, ukupholishwa kwenjoloba nokulawula ukusabela kwamakhemikhali, futhi ingasetshenziswa njenge-ejenti yokucisha umlilo.

Isicelo:

① Ukusetshenziswa Kwemboni:

I-carbon dioxide ene-high-purity isetshenziswa kakhulu embonini ye-electronics, ucwaningo lwezokwelapha kanye nokuxilongwa komtholampilo, i-carbon dioxide lasers, igesi yokulinganisa izinsimbi zokuhlola kanye nokulungiswa kwamanye amagesi ahlanganisiwe akhethekile, futhi isetshenziswa njengomlawuli ku-polyethylene polymerization.

②Isiqandisi kanye nokucisha:

I-carbon dioxide ewuketshezi isetshenziswa njengesiqandisi sokuhlola izinga lokushisa eliphansi lendiza, imicibisholo nezingxenye ze-electronic, ingasetshenziswa futhi njenge-ejenti yokucisha umlilo.
