Isichumisi esiPrilled urea
I-Urea inevumba le-ammonia kunye nencasa enetyuwa. Xa ubushushu bokufudumala buphezulu kunendawo yokunyibilika kwayo,
ibolile ibe yi-biuret, i-ammonia kunye ne-cynic acid. I-1g enyibilikayo kwi-1mL yamanzi, i-10ml 95% ye-ethanol, i-1ml 95%
i-ethanol ebilayo, i-20mL i-ethanol ene-anhydrous, i-6ml ye-methanol kunye ne-2mL ye-glycerol. Inyibilika kwi-hydrochloric egxininisiweyo
iasidi, phantse enganyibilikiyo kwi-ether kunye nekloroform. I-pH ye-10% yesisombululo se-aqueous yi-7.23. Iyacaphukisa.

Ureaisetyenziselwa uhlalutyo lwe-antimony kunye ne-tin. Ukuzimisela kwelothe, i-calcium, ithusi, i-gallium, i-phosphorus, i-iodide kunye
nitrate. Ukuzimisela kwegazi urea nitrogen, kunye nesisombululo esisemgangathweni, ukuzimisela kwe-serum bilirubin. Ukwahlulwa kwe
iihydrocarbons. I-nitric oxide kunye ne-nitrous acid esetyenziselwa ukubola i-nitrogen kuhlalutyo. Lungisa i medium. I-Folin
indlela yokuqinisekiswa kwe-uric acid stabilizer, i-homogeneous precipitation.
IiPropathi zoMmandla:Azimhlophe nge-radioactive, zihamba simahla, azinazinto eziyingozi ezigqunyiweyo, ezingqukuva kunye nezifanayo ngokobungakanani, 100% iphathwe ngokuchasene ne-caking.
Ukusetyenziswa: Isetyenziswa ngokuthe ngqo njengesichumiso okanye imathiriyeli ekrwada ye-NP/NPK yesichumiso. Ikwangumthombo wepolywood, iAdblue, iPlastiki, iResin, iPigment, iFied additive and Medicine Industry.
Ukupakishwa: ngobuninzi, kwi-50kg/1,000kg yesingxobo elukiweyo efakwe ngaphakathi kweplastiki ngokwezicelo zabathengi.
1. Enye yeenzuzo eziphambili ze-granular urea yi-solubility yayo ephezulu emanzini kunye ne-alcohols ehlukeneyo, okwenza kube lula ukuyifaka kunye nokuqinisekisa ukuthathwa ngokufanelekileyo kwezondlo zizityalo.
2. Ukuguquguquka kwayo kunye nokuhambelana neendlela ezahlukeneyo zokufaka izicelo ezifana nosasazo, ukunxitywa okuphezulu okanye ukuchumisa kwenza kube lukhetho lokuqala kumafama ajonge ukukhulisa iindlela zokulawula izichumiso.
3.ukwakheka kweekhemikhali zeurea granular, kubandakanywa ukubola kwayo kwi-biuret, i-ammonia kunye ne-cyanic acid kumaqondo aphezulu aphezulu, igxininisa amandla ayo okukhutshwa okulawulwayo kunye nemiphumo ehlala ixesha elide kwisondlo sezityalo. Oku kuyenza ibe yinto efanelekileyo kunikezelo lwezondlo oluqhubekayo kulo lonke ixesha lokukhula, ukunciphisa imfuno yokuphinda kufakwe izicelo rhoqo.
1. Kwezolimo, ukusetyenziswa kwezichumisi kubalulekile ukukhuthaza ukukhula kwezityalo okunempilo kunye nokwandisa isivuno sezityalo.
2.Urea lweGranular ine-ammonia kunye nencasa enetyuwa eyahlukileyo kwaye sisichumiso esityebile ngenitrogen esidlala indima ebalulekileyo ekukhuthazeni ukukhula kwezityalo. Xa igalelwe emhlabeni, ingena kwinkqubo ye-hydrolysis, ikhupha i-ammonium ion ezifunxwa lula ziingcambu zezityalo. Oku kwandisa ukuthathwa kwenitrogen, ngokwenjenjalo kukhuthaza ukukhula nophuhliso lwezityalo.
3.Kwezolimo, ukusetyenziswa kwezichumisi kubalulekile ukukhuthaza ukukhula kwezityalo okunempilo kunye nokwandisa isivuno sezityalo.
