Sulfur Dioxide (SO2)

Zosintha zaukadaulo

Sulfur dioxide (sulfure dioxide) ndi wofala kwambiri, wosavuta, komanso wokwiyitsa sulfure oxide wokhala ndi chilinganizo chamankhwala SO2.Sulfur dioxide ndi mpweya wopanda mtundu komanso wowonekera komanso wonunkhira bwino.Amasungunuka m'madzi, ethanol ndi ether, madzi a sulfure dioxide amakhala okhazikika, osagwira ntchito, osayaka, ndipo sapanga kusakaniza kophulika ndi mpweya.Sulfur dioxide ili ndi bleaching properties.Sulfur dioxide imagwiritsidwa ntchito kwambiri m'makampani kuyeretsa zamkati, ubweya, silika, zipewa zaudzu, ndi zina zambiri. Sulfur dioxide imathanso kulepheretsa kukula kwa nkhungu ndi mabakiteriya.Itha kugwiritsidwa ntchito ngati chosungira mumitundu yosiyanasiyana yazakudya monga zipatso zouma, masamba okazinga, ndi zinthu zanyama zokonzedwa (monga soseji ndi ma hamburger), koma ziyenera kutsatiridwa molingana ndi kuchuluka kwadziko komanso kugwiritsa ntchito Standard.Sulfur dioxide imagwiritsidwanso ntchito ngati organic zosungunulira ndi refrigerant, ndipo imagwiritsidwa ntchito kuyeretsa mafuta osiyanasiyana opaka mafuta;amagwiritsidwa ntchito popanga sulfure trioxide, sulfuric acid, sulfite, thiosulfate, komanso amagwiritsidwa ntchito ngati fumigant, preservative, mankhwala ophera tizilombo, ndi kuchepetsa wothandizira Etc.;amagwiritsidwa ntchito popanga sulfure komanso ngati mankhwala ophera tizilombo ndi fungicides.Njira zodzitetezera: kutsekedwa mwamphamvu, kupereka mpweya wokwanira wamba komanso mpweya wabwino.Ogwira ntchito ayenera kuphunzitsidwa mwapadera ndikutsata ndondomeko zoyendetsera ntchito.Ndikoyenera kuti ogwira ntchito azivala masks a gasi odzipangira okha (zophimba nkhope zonse), zovala zotetezera mpweya wa tepi, ndi magolovesi a labala.Khalani kutali ndi magwero a moto ndi kutentha, ndipo kusuta ndikoletsedwa kuntchito.Khalani kutali ndi zinthu zoyaka ndi zoyaka.Pewani mpweya kapena nthunzi kuti zisatayike mumlengalenga wapantchito.Pewani kukhudzana ndi zochepetsera.Kwezani pang'ono ndikutsitsa panthawi yamayendedwe kuti mupewe kuwonongeka kwa masilindala ndi zina.Zokhala ndi mitundu yofananira ndi kuchuluka kwa zida zozimitsa moto ndi zida zadzidzidzi zomwe zatuluka.Kusamala posungira: Sungani m'nyumba yosungiramo zinthu zoziziritsa kukhosi komanso mpweya wabwino.Khalani kutali ndi gwero la moto ndi kutentha.Kutentha kosungirako sikuyenera kupitirira 15°C.Iyenera kusungidwa mosiyana ndi zowotcha zosavuta (zoyaka), zochepetsera, ndi mankhwala odyedwa, ndikupewa kuzisakaniza.Malo osungiramo zinthu ayenera kukhala ndi zida zothandizira zadzidzidzi zomwe zatuluka.

Ntchito:

①Kalambulabwalo wa sulfuric acid:

Sulfur dioxide ndi yapakatikati popanga sulfuric acid, kusinthidwa kukhala sulfure trioxide, kenako kukhala oleum, yomwe imapangidwa kukhala sulfuric acid.

②Monga chochepetsera chosungira:

Sulfur dioxide nthawi zina imagwiritsidwa ntchito ngati chosungira ma apricots zouma, nkhuyu zouma, ndi zipatso zina zouma, imathandizanso kuchepetsa.

③Monga firiji:

Pokhala wofupikitsidwa mosavuta komanso kukhala ndi kutentha kwakukulu kwa nthunzi, sulfure dioxide ndi chinthu chopangira mafiriji.

Phukusi labwinobwino:

 Ubwino:

①Kupitilira zaka khumi pamsika;

② ISO wopanga satifiketi;

③Kutumiza mwachangu;

④Stable zopangira gwero;

⑤Dongosolo lowunikira pa intaneti pakuwongolera kwamtundu uliwonse;

⑥Kufunika kwakukulu komanso kusamala pogwira silinda musanadzaze;
