Mpweya wa carbon dioxide (CO2)

Zosintha zaukadaulo

Mpweya woipa wa carbon dioxide, wopangidwa ndi mpweya wa carbon oxygen, wokhala ndi mankhwala opangidwa ndi CO2, ndi mpweya wopanda mtundu, wopanda fungo kapena wopanda fungo wopanda utoto wokhala ndi kukoma kowawa pang'ono mu njira yake yamadzi pansi pa kutentha ndi kupanikizika. Komanso ndi wamba mpweya wowonjezera kutentha ndi chigawo chimodzi cha mpweya. Imodzi (yowerengera 0.03% -0.04% ya kuchuluka kwa mlengalenga). Pankhani ya zinthu zakuthupi, mpweya woipa ndi mpweya wopanda mtundu komanso wopanda fungo womwe umatentha kutentha komanso kupanikizika. Ili ndi kachulukidwe kakang'ono kuposa mpweya ndipo imasungunuka mu zosungunulira zambiri monga madzi ndi ma hydrocarbon. Pankhani ya mankhwala, imodzi mwa carbon dioxide carbon oxygen compounds ndi inorganic substance. Simagwiritsidwa ntchito ndi mankhwala ndipo imakhala ndi kukhazikika kwa kutentha kwambiri (kuwonongeka kwa 1.8% pa 2000 ° C). Sichingathe kuyaka, nthawi zambiri sichithandizira kuyaka, ndipo ndi acidic. Ma oxides ali ndi zinthu zofanana ndi ma acidic oxides. Chifukwa amachitira ndi madzi kuti apange carbonic acid, ndi anhydrides wa carbonic acid. Ponena za kawopsedwe kake, kafukufuku wasonyeza kuti mpweya wochepa wa carbon dioxide ulibe poizoni, pamene mpweya wochuluka wa carbon dioxide ukhoza kuwononga nyama. Mkulu-chiyero carbon dioxide zimagwiritsa ntchito mu makampani zamagetsi, kafukufuku zachipatala ndi matenda matenda, carbon dioxide lasers, calibration mpweya kwa zida kuyezetsa ndi yokonza mpweya wina wapadera wosanganiza, ndipo ntchito monga chowongolera polyethylene polymerization. Mpweya wa carbon dioxide umagwiritsidwa ntchito pa zakumwa zoziziritsa kukhosi, pH kulamulira mu njira zochizira madzi, kukonza mankhwala, kusunga chakudya, chitetezo cha inert mu mankhwala ndi chakudya, mpweya wowotcherera, chothandizira kukula kwa zomera, zomwe zimagwiritsidwa ntchito poyimitsa nkhungu ndi zipolopolo zomwe zimagwiritsidwa ntchito poponya zipangizo za pneumatic zimagwiritsidwanso ntchito ngati diluent kwa mpweya wochititsa chidwi (ie, osakaniza a ethylene ndi carbon dioxide ndi carbon dioxide ndi inctic oxide). Fumigant amagwiritsidwa ntchito kwambiri pochotsa zida zachipatala, zida zonyamula katundu, zovala, ubweya, zofunda, ndi zina zambiri. Zamadzimadzi carbon dioxide ntchito ngati refrigerant, otsika kutentha mayesero ndege, mivi ndi zigawo zikuluzikulu zamagetsi, kusintha mafuta bwino kuchira, kupukuta mphira ndi kulamulira zochita mankhwala, komanso angagwiritsidwe ntchito ngati wozimitsa moto wothandizila.

Ntchito:

①Kugwiritsa Ntchito Mafakitale:

Mkulu-chiyero carbon dioxide zimagwiritsa ntchito mu makampani zamagetsi, kafukufuku zachipatala ndi matenda matenda, carbon dioxide lasers, calibration mpweya kwa zida kuyezetsa ndi yokonza mpweya wina wapadera wosanganiza, ndipo ntchito monga chowongolera polyethylene polymerization.

②Refrigerant ndi kuzimitsa:

Mpweya wa carbon dioxide umagwiritsidwa ntchito ngati refrigerant yoyesera kutentha kwa ndege, mizinga ndi zipangizo zamagetsi, ingagwiritsidwenso ntchito ngati chozimitsa moto.
