I-Urea Efakwe Umanyolo
I-Urea inephunga le-ammonia kanye nokunambitheka okunosawoti. Lapho izinga lokushisa lokushisa liphakeme kunendawo yalo yokuncibilika,
ichithwa ibe yi-biuret, ammonia ne-cynic acid. 1g encibilika emanzini angu-1mL, 10ml 95% ethanol, 1ml 95%
i-ethanol ebilayo, 20mL i-ethanol anhydrous, 6ml methanol kanye ne-2mL glycerol. Incibilika ku-hydrochloric egxilile
i-asidi, cishe engancibiliki ku-ether ne-chloroform. I-pH engu-10% yesisombululo esinamanzi ngu-7.23. Iyacasula.
Inombolo ye-CAS: 57-13-6
Ifomula yemolekyuli: H2NCONH2
Umbala: omhlophe
Ibanga: IBanga Lemboni
Ubukhulu: 1.335
Indawo yokuncibilika: 132.7°C
Ubumsulwa%: Ubuncane 99.5%
Igama: Carbamide
I-Ureaisetshenziselwa ukuhlaziya i-antimony ne-tin. Ukunqunywa kokuhola, i-calcium, ithusi, i-gallium, i-phosphorus, i-iodide kanye
i-nitrate. Ukunqunywa kwe-urea nitrogen yegazi, ngesisombululo esijwayelekile, ukunqunywa kwe-serum bilirubin. Ukuhlukaniswa kwe
ama-hydrocarbons. I-nitric oxide ne-nitrous acid esetshenziselwa ukubola i-nitrogen ekuhlaziyeni. Lungiselela i-medium. I-Folin
indlela yokunquma i-uric acid stabilizer, imvula elinganayo.
Izakhiwo ezingokoqobo: Okumhlophe okungeyona imisebe, okugeleza mahhala, akunazinto eziyingozi ezimboziwe, okuyindilinga & umfaniswano ngosayizi, 100% welashwa ngokumelene ne-caking.
Ukusetshenziswa: Isetshenziswa ngokuqondile njengomanyolo noma impahla eluhlaza kamanyolo we-NP/NPK. Ibuye ibe ngumthombo we-polywood, i-Adblue, iPlastiki, i-Resin, i-Pigment, isithasiselo sokuphakelayo kanye nemboni yezokwelapha.
Iphakheji: ngobuningi, esikhwameni esilukiwe esingu-50kg/1,000kg esifakwe isikhwama sepulasitiki sangaphakathi ngokwezicelo zamakhasimende.
1. Enye yezinzuzo eziyinhloko ze-urea ye-granular ukuncibilika kwayo okuphezulu emanzini kanye notshwala obuhlukahlukene, okwenza kube lula ukusebenzisa nokuqinisekisa ukutholwa okuphumelelayo kwezakhi zezitshalo.
2. Ukuguquguquka kwayo nokuhambisana nezindlela ezihlukene zokufaka isicelo ezifana nokusakaza, ukugqoka okuphezulu noma ukuvundisa kwenza kube yisinqumo sokuqala kubalimi abafuna ukuthuthukisa izindlela zokuphatha umanyolo.
3.ukwakheka kwamakhemikhali weurea granular, okuhlanganisa ukubola kwayo ibe yi-biuret, i-ammonia ne-cynic acid emazingeni okushisa aphakeme, igqamisa amandla ayo okukhululwa okulawulwayo kanye nemiphumela ehlala isikhathi eside ekudleni kwezitshalo. Lokhu kuyenza ibe ilungele ukuhlinzekwa komsoco okuqhubekayo phakathi nenkathi yokukhula, kunciphisa isidingo sokuphinda kufakwe izicelo njalo.
1. Kwezolimo, ukusetshenziswa kukamanyolo kubalulekile ukukhuthaza ukukhula kwezitshalo okunempilo nokwandisa isivuno sezitshalo.
2.I-Granular urea inokunambitheka okuhlukile kwe-ammonia kanye nosawoti futhi iwumanyolo ocebile nge-nitrogen odlala indima ebalulekile ekuthuthukiseni ukukhula kwezitshalo. Uma ifakwa enhlabathini, ingena ohlelweni lwe-hydrolysis, ikhipha ama-ammonium ion adonswa kalula yizimpande zezitshalo. Lokhu kwandisa ukutholwa kwe-nitrogen, ngaleyo ndlela kukhuthaze ukukhula nokuthuthuka kwezitshalo.
3.Kwezolimo, ukusetshenziswa kukamanyolo kubalulekile ukukhuthaza ukukhula kwezitshalo okunempilo nokwandisa isivuno sezitshalo.
