Ethylene oxide & Carbon Dioxide Mixtures

Zosintha zaukadaulo

Ethylene oxide ndi imodzi mwama ethers osavuta a cyclic. Ndi gulu la heterocyclic. Njira yake yamakina ndi C2H4O. Ndi poizoni wa carcinogen komanso chinthu chofunikira kwambiri cha petrochemical. The mankhwala katundu wa ethylene okusayidi ndi yogwira. Imatha kukumana ndi mayamwidwe owonjezera owonjezera ndi mankhwala ambiri ndipo imatha kuchepetsa silver nitrate. N'zosavuta polymerize pambuyo pa kutentha ndipo akhoza kuwola pamaso pa zitsulo mchere kapena mpweya. Ethylene oxide ndi madzi opanda mtundu komanso owonekera potentha pang'ono, ndi mpweya wopanda mtundu wokhala ndi fungo loyipa la ether pakutentha koyenera. Kuthamanga kwa mpweya wa gasi ndi wokwera, kufika 141kPa pa 30 ° C. Kuthamanga kwa nthunzi kumeneku kumatsimikizira mphamvu ya epoxy Yamphamvu yolowera mkati mwa fumigation ya ethane ndi kupha tizilombo toyambitsa matenda. Ethylene oxide imakhala ndi bactericidal effect, siiwononga zitsulo, ilibe fungo lotsalira, ndipo imatha kupha mabakiteriya (ndi ma endospores ake), nkhungu ndi bowa, kotero ingagwiritsidwe ntchito kupha tizilombo ndi zinthu zina zomwe sizingathe kupirira kutentha kwa kutentha. . . Ethylene oxide ndi mankhwala ophera tizilombo m'badwo wachiwiri pambuyo pa formaldehyde. Akadali amodzi mwa mankhwala ozizira kwambiri opha tizilombo toyambitsa matenda. Ndiwonso matekinoloje anayi akuluakulu ochepetsa kutentha (kutsika kwa plasma, kutentha kwa formaldehyde nthunzi, ethylene oxide). , Glutaraldehyde) membala wofunikira kwambiri. Nthawi zambiri ntchito ethylene okusayidi-carbon dioxide (chiŵerengero cha awiri ndi 90:10) kapena ethylene okusayidi-dichlorodifluoromethane osakaniza, makamaka ntchito mankhwala zipatala ndi mwatsatanetsatane zida. Ethylene oxide ndi yoyaka komanso yophulika, ndipo mankhwala ake amagwira ntchito kwambiri. Ikhoza kukumana ndi zowonjezera zowonjezera zowonjezera ndi zowonjezera zambiri. Sikophweka kunyamula maulendo ataliatali, kotero ili ndi makhalidwe amphamvu achigawo. Kusamala posungira: Sungani m'nyumba yosungiramo zinthu zoziziritsa kukhosi komanso mpweya wabwino. Khalani kutali ndi gwero la moto ndi kutentha. Pewani kuwala. Kutentha kosungirako sikuyenera kupitirira 30°C. Iyenera kusungidwa mosiyana ndi zidulo, alkalis, mowa, ndi mankhwala odyedwa, ndipo pewani kusungidwa kosakanizidwa. Gwiritsani ntchito magetsi osaphulika komanso mpweya wabwino. Ndizoletsedwa kugwiritsa ntchito zida zamakina ndi zida zomwe zimakhala zosavuta kuphulika. Malo osungiramo zinthu ayenera kukhala ndi zida zothandizira zadzidzidzi zomwe zatuluka.

Ntchito:

①Kutsekera:

Ethylene oxide imakhala ndi bactericidal effect, siiwononga zitsulo, ilibe fungo lotsalira, ndipo imatha kupha mabakiteriya (ndi ma endospores ake), nkhungu ndi bowa, kotero ingagwiritsidwe ntchito kupha tizilombo ndi zinthu zina zomwe sizingathe kupirira kutentha kwa kutentha. .
