ICarbon Dioxide (CO2)

Iiparamitha zobugcisa

Ikhabhon diokside, uhlobo lwekhompawundi yekhabhoni yeoksijini, kunye nefomula yemichiza ye-CO2, yigesi engenambala, engenavumba okanye engenambala nencasa emuncu kancinane kwisisombululo sayo esinamanzi phantsi kobushushu obuqhelekileyo kunye noxinzelelo. Kwakhona yigesi eqhelekileyo ye-greenhouse kunye necandelo lomoya. Enye (i-akhawunti ye-0.03% -0.04% yomthamo opheleleyo we-atmosphere). Ngokubhekiselele kwiimpawu zomzimba, i-carbon dioxide yigesi engenambala kwaye engenavumba kubushushu begumbi kunye noxinzelelo. Inoxinano oluphezulu kunomoya kwaye iyanyibilika kuninzi lwezinyibilikisi eziphilayo ezifana namanzi kunye neehydrocarbons. Ngokweempawu zemichiza, enye yeekhompawundi zekharbon dioksijini ye-carbon oxygen yinto engabonakaliyo. Ayisebenzi ngamachiza kwaye inozinzo oluphezulu lwe-thermal (kuphela i-1.8% yokubola kwi-2000 ° C). Ayinakutshisa, ngokuqhelekileyo ayikuxhasi ukutsha, kwaye ineasidi. Iioksidi zineempawu ezifanayo njengee-acidic oxides. Ngenxa yokuba zisabela ngamanzi ukuvelisa i-carbonic acid, ziyi-anhydrides ye-carbonic acid. Ngokuphathelele ubutyhefu bayo, uhlolisiso luye lwabonisa ukuba i<em>carbon dioxide ekwiqondo eliphantsi ayinayo ityhefu, ngoxa i<em>carbon dioxide eninzi kakhulu inokutyhefa izilwanyana. Ucoceko oluphezulu lwekhabhon diokside lusetyenziswa kakhulu kwishishini le-electronics, uphando lwezonyango kunye nokuxilongwa kweklinikhi, i-carbon dioxide lasers, igesi yokulinganisa izixhobo zokuvavanya kunye nokulungiselela enye igesi ekhethekileyo edibeneyo, kwaye isetyenziswe njengomlawuli kwi-polymerization ye-polyethylene. I-gaseous carbon dioxide isetyenziselwa iziselo ezithambileyo ze-carbonized, ulawulo lwe-pH kwiinkqubo zokunyanga amanzi, ukusetyenzwa kweekhemikhali, ukugcinwa kokutya, ukukhuselwa kwe-inert kwimichiza kunye nokulungiswa kokutya, igesi ye-welding, i-stimulant yokukhula kwezityalo, esetyenziselwa ukuqinisa i-molds kunye ne-cores kwaye isetyenziselwa ukuphosa izixhobo ze-Pneumatic. zikwasetyenziswa njengesinyibilikisi segesi yokuvala inzala (oko kukuthi, umxube we-ethylene oxide kunye nekharbon diokside isetyenziswa njengento yokuvala inzala, isibulali zinambuzane, kunye nefumigant. Isetyenziswa kakhulu ekubulaleni inzala kwizixhobo zonyango, ukupakisha izinto, impahla, uboya, izinto zokulala. , njl. , Ukubulala iintsholongwane kwisidlo samathambo, ukutshisa kwiindawo zokugcina iimpahla, iifektri, izinto zenkcubeko, iincwadi). Ulwelo lwekhabhon dayoksayidi lusetyenziswa njengesikhenkcisi, uvavanyo lobushushu obuphantsi lwenqwelomoya, imijukujelwa kunye namalungu e-elektroniki, ukuphucula ukubuyiswa komthombo we-oyile, ukupolisha irabha kunye nolawulo lokusabela kweekhemikhali, kwaye inokusetyenziswa njenge-arhente yokucima umlilo.

Isicelo:

①Ukusetyenziswa kwemizi-mveliso:

Ucoceko oluphezulu lwekhabhon diokside lusetyenziswa kakhulu kwishishini le-electronics, uphando lwezonyango kunye nokuxilongwa kweklinikhi, i-carbon dioxide lasers, igesi yokulinganisa izixhobo zokuvavanya kunye nokulungiselela enye igesi ekhethekileyo edibeneyo, kwaye isetyenziswe njengomlawuli kwi-polymerization ye-polyethylene.

②Ifriji kunye nokucima:

Ulwelo lwekhabhon dayoksayidi lusetyenziswa njengesikhenkcisi kwiimvavanyo zobushushu obuphantsi benqwelomoya, imijukujelwa kunye nezinto zombane, lunokusetyenziswa njengesixhobo sokucima umlilo.
